Videos: Rare Glimpses of Amazing Birds-of-Paradise Courtship Rituals

Birds of paradise have evolved into very conspicuous animals with orange, red and turquoise plumage and ornate wire-like feathers that have captured the imagination of scientists and bird enthusiasts alike.

Their showy features are a delight to behold, but they would also make them an easy target for hungry cats and other predatory mammals -- if there were any around. The absence of such predators is precisely what allowed these otherwise impractical species to evolve.

"There was an evolutionary opportunity to develop that kind of extravagance," ornithologist Ed Scholes of the Cornell Lab of Ornithology said. "They're a quirk of geography."

More than 20 years ago, wildlife photographer Tim Laman saw his first birds of paradise, the Standardwing and the Red Bird of Paradise, while traveling in Indonesia. He started imagining a project to photograph every species of these birds in their natural habitats of New Guinea and parts of Australia.

"It was one of the dream assignments on my list," said Laman, who's also a rainforest biologist with a Ph.D. from Harvard.

Laman, whose work often focuses on conservation, finally pitched the project to National Geographic in 2003. He teamed up with Scholes, and during the next three years the pair made five trips to New Guinea and managed to photograph about half of the 39 species of birds of paradise.

After eight years, Laman and Scholes completed their mission of photographing all of the bird-of-paradise species, including the ballerina-like bronze parotia, which only recently was recognized as the 39th species.

The project took Laman and Scholes through more than 200 flights, 18 expeditions and thousands of hours spent hiding in blinds as high as 50 meters above ground. They set up a battery-powered jungle ethernet and remote-controlled cameras hooked up to laptops to take the nearly 40,000 photographs that comprise the Birds of Paradise Project.

Here is a selection of some of the best videos and photos from their avian adventures.

Goldie’s birds-of-paradise live on two or three islands on the western edge of Papua New Guinea.

Males coordinate their displays and their calls sound almost like an intense duet, says Scholes.

Australian DJs break silence over UK royal prank tragedy

CANBERRA (Reuters) – Two Australian radio announcers who made a prank call to a British hospital treating Prince William‘s pregnant wife Kate broke a three-day silence on Monday to speak of their distress at the apparent suicide of the nurse who took their call.

The 2DayFM Sydney-based announcers, Mel Greig and Michael Christian, said the tragedy had left them “shattered, gutted, heartbroken”.

Greig and fellow presenter and prank mastermind Christian have been in hiding since nurse Jacintha Saldanha‘s death and the subsequent social media outrage at their prank.

Their show, “Hot 30,” has been terminated, the station’s parent company, Southern Cross Austereo (SCA), said in a statement on Monday. SCA also announced a company-wide suspension of prank calls.

Greig told Australian television her first thought when told of Saldanha‘s death was for her family.

“Unfortunately I remember that moment very well, because I haven’t stopped thinking about it since it happened,” she said, amid tears and her voice quavering with emotion. “I remember my first question was ‘was she a mother?’”

“I’ve wanted to just reach out to them and just give them a big hug and say sorry. I hope they’re okay, I really do. I hope they get through this,” said a black-clad Greig when asked about mother of two Saldanha’s children, left grieving their mother’s death with their father Ben Barboza.

Saldanha, 46, was found dead in staff accommodation near London’s King Edward VII hospital on Friday after putting the hoax call through to a colleague who unwittingly disclosed details of Kate’s morning sickness to 2DayFM’s presenters.

British Prime Minister David Cameron said news of the Saldanha’s death was “shocking”.

“I just feel incredibly sorry for her and her family. It’s an absolute tragedy this has happened, and I’m sure everyone will want to reflect on how it was allowed to happen,” he said.

The hospital at which Saldanha worked told the BBC it had not disciplined her for taking the prank call. Police said a post-mortem examination would be conducted on Tuesday.

FIRESTORM

A recording of the call, broadcast repeatedly by the station, rapidly became an internet hit and was reprinted as a transcript in many newspapers.

But news of Saldanha’s death sparked the Internet firestorm, with vitriolic comments towards the DJs on Facebook and Twitter.

Christian said his only wish was that Saldanha’s grief-stricken family received proper support.

“I hope that they get the love, the support, the care that they need, you know,” said Christian, who like Greig struggled to talk about the tragedy.

Both Greig, 30, and Christian were relatively new to the station, with Greig joining in March and Christian having been in the job only a few days before the prank call after a career in regional radio.

Greig said she did not think their prank would work.

“We thought a hundred people before us would’ve tried it. We thought it was such a silly idea and the accents were terrible and not for a second did we expect to speak to Kate, let alone have a conversation with anyone at the hospital. We wanted to be hung up on,” she said.

Christian drew headlines only two weeks before the royal prank call by angering fellow passengers with a harmonica playing stunt aboard pop star Rihanna’s private jet.

SCA, 2Day’s parent company, has received more than 1,000 complaints from Australians over the actions of the popular presenters, who have both been taken off air during an broadcasting watchdog investigation.

“SCA and the hosts of the radio program have also decided that they will not return to the airwaves until further notice,” SCA said in a statement.

Shares in SCA fell 5 percent on Monday after two major Australian companies pulled their advertising with the radio station in protest and other advertising was suspended.

The station said it had tried to contact hospital staff five times over the recordings.

“It is absolutely true to say that we actually did attempt to contact those people on multiple occasions,” said SCA chief executive Rhys Holleran.

“No one could have reasonably foreseen what has happened. I can only say the prank call is not unusual around the world,” he said.

The fallout from the radio stunt has brought back memories in Britain of the death of William’s mother Diana in a Paris car crash in 1997 and threatens to cast a pall over the birth of his and Kate’s first child.

Australia’s Communications Minister Stephen Conroy sought to deflect calls for more media regulation, telling journalists that a looming investigation by Australia’s independent regulator should be allowed to happen without political interference.

A Breakthrough Against Leukemia Using Altered T-Cells

PHILIPSBURG, Pa. — Emma Whitehead has been bounding around the house lately, practicing somersaults and rugby-style tumbles that make her parents wince.

It is hard to believe, but last spring Emma, then 6, was near death from leukemia. She had relapsed twice after chemotherapy, and doctors had run out of options.

Desperate to save her, her parents sought an experimental treatment at the Children’s Hospital of Philadelphia, one that had never before been tried in a child, or in anyone with the type of leukemia Emma had. The experiment, in April, used a disabled form of the virus that causes AIDS to reprogram Emma’s immune system genetically to kill cancer cells.

The treatment very nearly killed her. But she emerged from it cancer-free, and about seven months later is still in complete remission. She is the first child and one of the first humans ever in whom new techniques have achieved a long-sought goal — giving a patient’s own immune system the lasting ability to fight cancer.

Emma had been ill with acute lymphoblastic leukemia since 2010, when she was 5, said her parents, Kari and Tom. She is their only child.

She is among just a dozen patients with advanced leukemia to have received the experimental treatment, which was developed at the University of Pennsylvania. Similar approaches are also being tried at other centers, including the National Cancer Institute and Memorial Sloan-Kettering Cancer Center in New York.

“Our goal is to have a cure, but we can’t say that word,” said Dr. Carl June, who leads the research team at the University of Pennsylvania. He hopes the new treatment will eventually replace bone-marrow transplantation, an even more arduous, risky and expensive procedure that is now the last hope when other treatments fail in leukemia and related diseases.

Three adults with chronic leukemia treated at the University of Pennsylvania have also had complete remissions, with no signs of disease; two of them have been well for more than two years, said Dr. David Porter. Four adults improved but did not have full remissions, and one was treated too recently to evaluate. A child improved and then relapsed. In two adults, the treatment did not work at all. The Pennsylvania researchers were presenting their results on Sunday and Monday in Atlanta at a meeting of the American Society of Hematology.

Despite the mixed results, cancer experts not involved with the research say it has tremendous promise, because even in this early phase of testing it has worked in seemingly hopeless cases. “I think this is a major breakthrough,” said Dr. Ivan Borrello, a cancer expert and associate professor of medicine at the Johns Hopkins University School of Medicine.

Dr. John Wagner, the director of pediatric blood and marrow transplantation at the University of Minnesota, called the Pennsylvania results “phenomenal” and said they were “what we’ve all been working and hoping for but not seeing to this extent.”

A major drug company, Novartis, is betting on the Pennsylvania team and has committed $20 million to building a research center on the university’s campus to bring the treatment to market.

Hervé Hoppenot, the president of Novartis Oncology, called the research “fantastic” and said it had the potential — if the early results held up — to revolutionize the treatment of leukemia and related blood cancers. Researchers say the same approach, reprogramming the patient’s immune system, may also eventually be used against tumors like breast and prostate cancer.

To perform the treatment, doctors remove millions of the patient’s T-cells — a type of white blood cell — and insert new genes that enable the T-cells to kill cancer cells. The technique employs a disabled form of H.I.V. because it is very good at carrying genetic material into T-cells. The new genes program the T-cells to attack B-cells, a normal part of the immune system that turn malignant in leukemia.

The altered T-cells — called chimeric antigen receptor cells — are then dripped back into the patient’s veins, and if all goes well they multiply and start destroying the cancer.

The T-cells home in on a protein called CD-19 that is found on the surface of most B-cells, whether they are healthy or malignant.

A sign that the treatment is working is that the patient becomes terribly ill, with raging fevers and chills — a reaction that oncologists call “shake and bake,” Dr. June said. Its medical name is cytokine-release syndrome, or cytokine storm, referring to the natural chemicals that pour out of cells in the immune system as they are being activated, causing fevers and other symptoms. The storm can also flood the lungs and cause perilous drops in blood pressure — effects that nearly killed Emma.

Steroids sometimes ease the reaction, but they did not help Emma. Her temperature hit 105. She wound up on a ventilator, unconscious and swollen almost beyond recognition, surrounded by friends and family who had come to say goodbye.

But at the 11th hour, a battery of blood tests gave the researchers a clue as to what might help save Emma: her level of one of the cytokines, interleukin-6 or IL-6, had shot up a thousandfold. Doctors had never seen such a spike before and thought it might be what was making her so sick.

Dr. June knew that a drug could lower IL-6 — his daughter takes it for rheumatoid arthritis. It had never been used for a crisis like Emma’s, but there was little to lose. Her oncologist, Dr. Stephan A. Grupp, ordered the drug. The response, he said, was “amazing.”

Within hours, Emma began to stabilize. She woke up a week later, on May 2, the day she turned 7; the intensive-care staff sang “Happy Birthday.”

Since then, the research team has used the same drug, tocilizumab, in several other patients.

In patients with lasting remissions after the treatment, the altered T-cells persist in the bloodstream, though in smaller numbers than when they were fighting the disease. Some patients have had the cells for years.

Dr. Michel Sadelain, who conducts similar studies at the Sloan-Kettering Institute, said: “These T-cells are living drugs. With a pill, you take it, it’s eliminated from your body and you have to take it again.” But T-cells, he said, “could potentially be given only once, maybe only once or twice or three times.”

The Pennsylvania researchers said they were surprised to find any big drug company interested in their work, because a new batch of T-cells must be created for each patient — a far cry from the familiar commercial strategy of developing products like Viagra or cholesterol medicines, in which millions of people take the same drug.

Advertising: In Beyoncé Deal, Pepsi Focuses on Collaboration

Beyoncé at a Pepsi photo shoot in October. The images will appear early next year as life-size cardboard cutouts in stores.

FOR its campaign with Beyoncé next year, Pepsi doesn’t just want to sign up the telegenic pop star for another TV commercial. It also wants to get into the Beyoncé business.

In an expansion of the recent marketing experiments that have brought PepsiCo ever closer to the music industry, the company has embarked on a hybrid project with Beyoncé that will include standard advertising like commercials as well as a multimillion-dollar fund to support the singer’s chosen creative projects.

“Pepsi embraces creativity and understands that artists evolve,” Beyoncé said in a statement. “As a businesswoman, this allows me to work with a lifestyle brand with no compromise and without sacrificing my creativity.”

The campaign will coincide with a blitz of promotion for her next album, which has no title or release date so far but is expected in 2013. Sometime after she performs at the Super Bowl halftime show on Feb. 3 (also sponsored by Pepsi), Beyoncé will appear in a new TV ad — her fifth for the soft drink since 2002 — and her face will be on a limited-edition line of soda cans.

The less conventional aspects of the deal are meant as collaborative projects that indulge Beyoncé’s creative whims, and might well have no explicit connection to Pepsi products. They are still at the brainstorm stage, but could include live events, videos, “a cool photo shoot” or almost anything else, said Lee Anne Callahan-Longo, the general manager of Parkwood Entertainment, Beyoncé’s company.

For Pepsi, the goal is to enhance its reputation with consumers by acting as something of an artistic patron instead of simply paying for celebrity endorsements.

“Consumers are seeking a much greater authenticity in marketing from the brands they love,” said Brad Jakeman, president of PepsiCo’s global beverage group. “It’s caused a shift in the way we think about deals with artists, from a transactional deal to a mutually beneficial collaboration.”

The multiyear campaign is estimated at $50 million, the bulk of it for media placements and promotions around the world, and the remainder split roughly equally between Beyoncé’s fee and what Pepsi calls a creative content development fund.

•

According to the tracking firm Kantar Media, PepsiCo and its archrival the Coca-Cola Company each spent about $148 million in the United States to advertise their soft drink brands in the first six months of 2012, across all measured forms of media, like television, print, digital and radio.

Over the last decade many consumer brands have been taking more active roles with artists, particularly in pop music. Converse, Red Bull and Toyota’s Scion line, for example, have become as familiar in the music business as any label or concert promoter by paying to help create and promulgate music.

Bands always risk fan disapproval when shaking hands with big corporations. But with record company budgets diminished, Madison Avenue money is often seen as essential. PepsiCo has been part of this trend through Green Label Sound, a label financed through its Mountain Dew drink, which over the last four years has paid to release free music by under-the-radar groups like Matt & Kim and the Cool Kids.

“We recognize that there have been massive disruptions in music industry: lower investment in artist development, fewer points of distribution, financial constraints,” said Frank Cooper, a top marketing executive in PepsiCo’s beverage division who has been a force for such projects. “We look at those disruptions as opportunities for Pepsi.”

These deals are not limited to music. In 2010, Jay-Z (Beyoncé’s husband) teamed with Microsoft to promote his memoir, “Decoded.” According to a case study led by Anita Elberse, a Harvard Business School professor, the publisher could contribute only $50,000 for marketing, but Microsoft paid $2 million for an elaborate scavenger hunt that promoted the book as well as its new search engine, Bing.

3 killed, 4 wounded in Tulare County shooting

Three people were fatally shot and four others wounded, including two young children, Saturday night on the Tule River Reservation in Tulare County, authorities said.

The suspect, who fled with his two young daughters, was later shot by sheriff’s deputies and taken into custody, according to the Tulare County Sheriff’s Department. The two girls, who were among those shot, were rescued.

The incident began about 7:45 p.m. when the Sheriff’s Department received a 911 call about shots fired in the 100 block of Chimney Road of the Tule River Indian Reservation about 60 miles northeast of Bakersfield, according to a Sheriff’s Department statement.

In a trailer on the property, deputies discovered an adult male and an adult female who had been fatally shot, authorities said. A male juvenile who suffered a gunshot wound was transported to a hospital. 

At a shed on the property, deputies found another male victim who had been fatally shot, authorities said.

The suspect, identified as Hector Celaya, 31, of the Tule River Indian Reservation, fled the scene in a Jeep Cherokee with his two daughters, Alyssa, 8, and Linea, 5, authorities said. An Amber Alert was issued around 11 p.m.

Detectives used Celaya’s cellphone to locate him.

A deputy spotted the vehicle and after failing to make a traffic stop, a slow-speed pursuit began, authorities said.

The suspect eventually stopped and fired his weapon at deputies, who returned fire and struck the suspect twice, seriously wounding him, authorities said.

New Crowdfunding Site Seeks to Protect Backers of Industrial Design

Entrepreneur Jamie Siminoff wants to build more credibility into crowdfunding — so he’s launching a new platform that takes responsibility for ensuring the viability of new projects.

The crowdfunding process, pioneered by sites like Kickstarter, has had its share of huge successes, as well as failures. The problem, says Siminoff, is that when a venture fails, the funders are left holding the bag. That’s all well and good if you were investing in an artist’s crazy project. It’s much more of a problem if you thought you were pre-ordering a nearly finished gadget.

The biggest culprit for these kinds of issues are physical products. Witness the anger unleashed when Kickstarter darling Pebble announced a further delay alongside underwhelming color choices.

This kind of issue is why Kickstarter recently made some changes, undertaking a combination of education and rule revision. They reminded consumers that Kickstarter is not a store while requiring that all projects disclose risks and challenges, as well as forbidding renderings and concept videos in hardware products.

Siminoff’s answer is Christie Street, a crowdfunding site devoted exclusively to physical products. The promise of Christie Street is that it will vet the projects that it launches carefully, and provide guarantees of progress along the way. The idea is that these protections will make consumers feel safer about the products they’re backing. “We built something that we felt we needed,” he says.

Christie Street, named for the New Jersey road where Edison’s workshop was located, will require that all funders go through an auditing process before they are allowed to go live. Siminoff says that the idea will be to check for basic viability, a kind of sanity test.

“You look at the chips they say they want to use, the size of components that will need to fit in, and so on,” he says, “You check that things conform to what’s available on the market.” From there, they also perform third-party audits of the places where the product will be manufactured, and look at things like production cost and likely shipping time, to ensure that all of this seems realistic.

It’s an all-or-nothing audit. Either the new project meets Christie Street’s approval or it doesn’t. “Our feeling is that the customer that’s buying doesn’t have the sophistication to make the right decision [about whether a design's production targets are reliable],” says Siminoff, “The only way is create a place where you can trust to buy.”

Even after the initial approval, Christie Street stays involved in the project. Successfully funded projects get their money in stages, with Christie Street holding the rest in escrow. Inventors get one-third of the money on funding, one-third of the money once they have a production-ready prototype, and the final one-third when they have a golden prototype, which means they are ready for full manufacturing.

If at any time along the way the project fails, Christie Street will can the project and refund the remaining money to investors.

What constitutes failure? Siminoff ticks off four conditions.

First, the inventor could for whatever reason announce that they couldn’t finish.

Second, if the project ends up more than six months late. “This forces people to be more careful with their delivery dates,” says Siminoff.

Third, if the product falls short of what was promised. “If the pre-production sample is more than 15 percent worse than what was promised, we will not allowed you to manufacture the product,” says Siminoff. (For example, if you promised me 512GB and only delivered 256.)

Last, says Siminoff there are other nuances that they’ll have to work out as the site develops. For example, if a product ends up requiring significant redesign, then Christie Street might end up withholding funds. “Design is a tougher one to quantify,” he says, “but it’s important that the design overall fits what was promised to the customer.”

For the extra cautious, Christie Street goes even further than the refund of remaining money. For 10 percent of their pledge value, backers can insure their entire pledge. If the project goes wrong they’ll get all of it back. Combine that with a pledge from inventors that the product will retail for at least 10 percent more than the pledge amount, and you can either take a 10 percent discount for some additional risk or pay full retail, with a money-back guarantee.

In effect, Christie Street is navigating a space between crowfunding sites like Kickstarter and Indiegogo, which expect backers to handle a lot of their own due diligence while allowing the inventors to be entrepreneurs, and crowdsourcing design sites like Quirky, which handles all of the business elements in-house.

Christie Street is an effort at drawing the lines of trust in a new way, one tied directly to the realities of post-industrial product design. Rather than a blanket ban on renderings and early designs, or a Wild West ‘anything goes’ approach, they instead seeks to tame the parts where production can go really wrong, in the devilish details of prototyping and manufacturing. It leaves questions of whether or not the thing is cool to the wisdom of the crowds, while taking on the question of whether or not the thing is possible.

This is obviously a lot more intervention between middleman and inventor than you’d see on a site like Indigegogo or Kickstarter. Siminoff says that they can still take the same 5 percent cut as their competitors because physical products tend to be involved higher dollar-value projects from the start. “If all goes well, we’ll be doing 10 to 15 live projects a months a year from now,” he says, “We think we can be profitable in the product world.”

“We’re not trying to make it where inventors are just be a name on a product,” says Siminoff, “We still want them to be entrepreneur and build this thing. We just want to make sure that they don’t fail in a way that hurts the customer.”

Cablevision to raise Internet prices by $5 a month

(Reuters) – Cablevision Systems Corp, the New York-based cable operator, said on Thursday it would raise its Internet prices by $ 5 in January, representing an average hike of 3.2 percent for customers’ total monthly bills.

The company said in a statement that prices for its video and phone services will not be affected and that prices for promotional packages, which generally last one year, will not rise.

But all customers who have Internet service as part of their video or phone package will see prices rise.

Cablevision said it had not raised Internet prices in a decade. It raised video prices in 2011, which saw customer bills rise by 2.88 percent on average.

The company said it has invested $ 140 million in improving its Internet network, deployed more than 50,000 WiFi “hotspots,” and puts no usage caps on its service, unlike some cable competitors.

Canaccord Genuity analyst Tom Eagan downgraded his Cablevision rating from “buy” to “hold” on November 27 and said that Cablevision would lose customers if it were to decide to raise prices not long after Superstorm Sandy.

“Given the massive service outages among its subscribers (after Sandy), we don’t believe the company can raise rates … without incurring material customer churn,” Eagan said.

The cable provider, which is controlled by the Dolan family, said in early November that costs from Sandy, which knocked out service for as many as half its customers, would be substantially higher than its $ 16 million bill from Hurricane Irene in 2011.

Like bigger operators Comcast and Time Warner Cable, Cablevision has been losing customers to rivals such as satellite television provider DirecTV and telephone operator Verizon Communications.

Cablevision shares closed up 2.6 percent, at $ 14.16, on Thursday.

New Taxes to Take Effect to Fund Health Care Law

WASHINGTON — For more than a year, politicians have been fighting over whether to raise taxes on high-income people. They rarely mention that affluent Americans will soon be hit with new taxes adopted as part of the 2010 health care law.

The new levies, which take effect in January, include an increase in the payroll tax on wages and a tax on investment income, including interest, dividends and capital gains. The Obama administration proposed rules to enforce both last week.

Affluent people are much more likely than low-income people to have health insurance, and now they will, in effect, help pay for coverage for many lower-income families. Among the most affluent fifth of households, those affected will see tax increases averaging $6,000 next year, economists estimate.

To help finance Medicare, employees and employers each now pay a hospital insurance tax equal to 1.45 percent on all wages. Starting in January, the health care law will require workers to pay an additional tax equal to 0.9 percent of any wages over $200,000 for single taxpayers and $250,000 for married couples filing jointly.

The new taxes on wages and investment income are expected to raise $318 billion over 10 years, or about half of all the new revenue collected under the health care law.

Ruth M. Wimer, a tax lawyer at McDermott Will & Emery, said the taxes came with “a shockingly inequitable marriage penalty.” If a single man and a single woman each earn $200,000, she said, neither would owe any additional Medicare payroll tax. But, she said, if they are married, they would owe $1,350. The extra tax is 0.9 percent of their earnings over the $250,000 threshold.

Since the creation of Social Security in the 1930s, payroll taxes have been levied on the wages of each worker as an individual. The new Medicare payroll is different. It will be imposed on the combined earnings of a married couple.

Employers are required to withhold Social Security and Medicare payroll taxes from wages paid to employees. But employers do not necessarily know how much a worker’s spouse earns and may not withhold enough to cover a couple’s Medicare tax liability. Indeed, the new rules say employers may disregard a spouse’s earnings in calculating how much to withhold.

Workers may thus owe more than the amounts withheld by their employers and may have to make up the difference when they file tax returns in April 2014. If they expect to owe additional tax, the government says, they should make estimated tax payments, starting in April 2013, or ask their employers to increase the amount withheld from each paycheck.

In the Affordable Care Act, the new tax on investment income is called an “unearned income Medicare contribution.” However, the law does not provide for the money to be deposited in a specific trust fund. It is added to the government’s general tax revenues and can be used for education, law enforcement, farm subsidies or other purposes.

Donald B. Marron Jr., the director of the Tax Policy Center, a joint venture of the Urban Institute and the Brookings Institution, said the burden of this tax would be borne by the most affluent taxpayers, with about 85 percent of the revenue coming from 1 percent of taxpayers. By contrast, the biggest potential beneficiaries of the law include people with modest incomes who will receive Medicaid coverage or federal subsidies to buy private insurance.

Wealthy people and their tax advisers are already looking for ways to minimize the impact of the investment tax — for example, by selling stocks and bonds this year to avoid the higher tax rates in 2013.

The new 3.8 percent tax applies to the net investment income of certain high-income taxpayers, those with modified adjusted gross incomes above $200,000 for single taxpayers and $250,000 for couples filing jointly.

David J. Kautter, the director of the Kogod Tax Center at American University, offered this example. In 2013, John earns $160,000, and his wife, Jane, earns $200,000. They have some investments, earn $5,000 in dividends and sell some long-held stock for a gain of $40,000, so their investment income is $45,000. They owe 3.8 percent of that amount, or $1,710, in the new investment tax. And they owe $990 in additional payroll tax.

The new tax on unearned income would come on top of other tax increases that might occur automatically next year if President Obama and Congress cannot reach an agreement in talks on the federal deficit and debt. If Congress does nothing, the tax rate on long-term capital gains, now 15 percent, will rise to 20 percent in January. Dividends will be treated as ordinary income and taxed at a maximum rate of 39.6 percent, up from the current 15 percent rate for most dividends.

Under another provision of the health care law, consumers may find it more difficult to obtain a tax break for medical expenses.

Taxpayers now can take an itemized deduction for unreimbursed medical expenses, to the extent that they exceed 7.5 percent of adjusted gross income. The health care law will increase the threshold for most taxpayers to 10 percent next year. The increase is delayed to 2017 for people 65 and older.

In addition, workers face a new $2,500 limit on the amount they can contribute to flexible spending accounts used to pay medical expenses. Such accounts can benefit workers by allowing them to pay out-of-pocket expenses with pretax money.

Taken together, this provision and the change in the medical expense deduction are expected to raise more than $40 billion of revenue over 10 years.

Changes to Agriculture Highlight Cuba’s Problems

HAVANA — Cuba’s liveliest experiment with capitalism unfolds every night in a dirt lot on the edge of the capital, where Truman-era trucks lugging fresh produce meet up with hundreds of buyers on creaking bicycle carts clutching wads of cash.

“This place, it feeds all of Havana,” said Misael Toledo, 37, who owns three small food stores in the city. “Before, you could only buy or sell in the markets of Fidel.”

The agriculture exchange, which sprang up last year after the Cuban government legalized a broader range of small businesses, is a vivid sign of both how much the country has changed, and of all the political and practical limitations that continue to hold it back.

President Raúl Castro has made agriculture priority No. 1 in his attempt to remake the country. He used his first major presidential address in 2007 to zero in on farming, describing weeds conquering fallow fields and the need to ensure that “anyone who wants can drink a glass of milk.”

No other industry has seen as much liberalization, with a steady rollout of incentives for farmers. And Mr. Castro has been explicit about his reasoning: increasing efficiency and food production to replace imports that cost Cuba hundreds of millions of dollars a year is a matter “of national security.”

Yet at this point, by most measures, the project has failed. Because of waste, poor management, policy constraints, transportation limits, theft and other problems, overall efficiency has dropped: many Cubans are actually seeing less food at private markets. That is the case despite an increase in the number of farmers and production gains for certain items. A recent study from the University of Havana showed that market prices jumped by nearly 20 percent in 2011 alone. And food imports increased to an estimated $1.7 billion last year, up from $1.4 billion in 2006.

“It’s the first instance of Cuba’s leader not being able to get done what he said he would,” said Jorge I. Domínguez, vice provost for international affairs at Harvard, who left Cuba as a boy. “The published statistical results are really very discouraging.”

A major cause: poor transportation, as trucks are in short supply, and the aging ones that exist often break down.

In 2009, hundreds of tons of tomatoes, part of a bumper crop that year, rotted because of a lack of transportation by the government agency charged with bringing food to processing centers.

“It’s worse when it rains,” said Javier González, 27, a farmer in Artemisa Province who described often seeing crops wilt and rot because they were not picked up.

Behind him were the 33 fertile, rent-free acres he had been granted as part of a program Mr. Castro introduced in 2008 to encourage rural residents to work the land. After clearing it himself and planting a variety of crops, Mr. Gonzalez said, he was doing relatively well and earned more last year than his father, who is a doctor, did.

But Cuba’s inefficiencies gnawed at him. Smart, strong, and ambitious, he had expansion plans in mind, even as in his hand he held a wrench. He was repairing a tractor part meant to be grading land. It was broken. Again.

The 1980s Soviet model tractor he bought from another farmer was as about good as it gets in Cuba. The Cuban government maintains a monopoly on selling anything new, and there simply is not enough of anything — fertilizer, or sometimes even machetes — to go around.

Government economists are aware of the problem. “If you give people land and no resources, it doesn’t matter what happens on the land,” said Joaquin Infante of the Havana-based Cuban National Association of Economists.

But Mr. Castro has refused to allow what many farmers and experts see as an obvious solution to the shortages of transportation and equipment: Let people import supplies on their own. “It’s about control,” said Philip Peters, a Cuba analyst with the Lexington Institute, a Virginia-based research group.

Other analysts agree, noting that though the agricultural reforms have gone farther than other changes — like those that allow for self-employment — they remain constrained by politics.

“The government is not ready to let go,” said Ted Henken, a Latin American studies professor at Baruch College. “They are sending the message that they want to let go, or are trying to let go, but what they have is still a mechanism of control.”

For many farmers, that explains why land leases last for 10 years with a chance to renew, not indefinitely or the 99 years offered to foreign developers. It is also why many farmers say they will not build homes on the land they lease, despite a concession this year to allow doing so.

Surgeon infected patients during heart procedure, Cedars-Sinai admits

A heart surgeon at Cedars-Sinai Medical Center unwittingly infected five patients during valve replacement surgeries earlier this year, causing four of the patients to need a second operation.

The infections occurred after tiny tears in the latex surgical gloves routinely worn by the doctor allowed bacteria from a skin inflammation on his hand to pass into the patients' hearts, according to the hospital. The patients survived the second operation and are still recovering, hospital officials said.

The outbreak led to investigations by the hospital and both the L.A. County and California departments of public health. The federal Centers for Disease Control and Prevention was also consulted.

Hospital officials called it a "very unusual occurrence" probably caused by an unfortunate confluence of events: the nature of the surgery, the microscopic rips in the gloves and the surgeon's skin condition. Valve replacement requires the surgeon to use thick sutures and tie more than 100 knots, which can cause extra stress on the gloves, they said.

Nevertheless, the hospital's goal is to have zero infections, said Harry Sax, vice chairman of the hospital's department of surgery. "Any hospital-acquired infection is unacceptable," he said.

The infections raise questions about what health conditions should prevent a surgeon from operating and how to get the best protection from surgical gloves. Surgeons with open sores or known infections aren't supposed to operate, but there is no national standard on what to do if they have skin inflammation, said Rekha Murthy, medical director of the hospital's epidemiology department. She added that there were also no national standards on types of gloves used, whether to wear double gloves or how many times surgeons should change those gloves during a procedure.

Healthcare-acquired infections are very common throughout the United States. Each year, infections cause 99,000 deaths in the country, including about 12,000 in California. Hospitals in the state are required to report certain infections to the California Department of Public Health. That reporting makes the public more aware of the quality of care provided at local hospitals and is an important tool for reducing infections, said Debby Rogers, deputy director of the department's Center for Health Care Quality.

Cedars-Sinai has low rates for hospital-acquired infections compared with the state and national average but has not performed as well on other surgical quality measures recently, according to the Leapfrog Group, an employer-backed nonprofit focused on healthcare quality. The organization gave the hospital a C rating last month on its national report card, down from an A in June, though it was not related to the infection outbreak.

"Clearly this hospital is making attempts to reduce infections, but they have more work to do," said Leah Binder, Leapfrog's chief executive.

Cedars-Sinai Medical Center conducts about 360 valve replacement surgeries each year and said infections occur in fewer than 1% of its cases — lower than the national average.

The hospital learned about the problem in June after three patients who had undergone valve replacement surgery showed signs of infection. Doctors diagnosed the patients with an infection called endocarditis. Concerned there might be a connection among the cases, epidemiologists analyzed the bacteria, staphylococcus epidermidis, and determined that it was an identical strain and therefore must have come from a single source. "It led to the question of gee, I wonder where it came from?" Murthy said.

Epidemiologists homed in on the surgeon with the skin inflammation. The bacteria matched, and then they made a surprising discovery: microscopic tears in the gloves typically worn by surgeons after performing valve replacement surgery. The surgeon, whose name was not released, was not allowed to operate again until he healed. He is still a member of the medical staff but no longer performs surgeries at the hospital.

The hospital soon found the same infection in two more patients. Officials also reached out to 67 patients who had heart valve replacements with the same surgeon but didn't find any other cases. One of the five infected patients was treated with antibiotics, and the other four had new valve replacement surgeries. Sax said the hospital apologized to the patients and has continued to monitor their health. The hospital has also covered the cost of their care, including follow-up treatment and all the related surgeries.

All surgeons doing valve replacements are now required to change gloves more frequently, officials said. Some surgeons are wearing double gloves during the operations, Sax said.

Following the outbreak, Cedars-Sinai did the proper follow-up to ensure the safety of their patients, said Dawn Terashita, a medical epidemiologist with L.A. County, who was notified in September. What occurred at Cedars-Sinai was an unintentional consequence of the surgery, she said.

"There is no way to keep a room entirely sterile and all the people in it sterile," she said. "You will always have risk of infection."
