Brown plans extensive changes for school funding in 2013

SACRAMENTO — Gov. Jerry Brown will push this year to upend the way schools are funded in California, hoping to shift more money to poorer districts and end requirements that billions of dollars be spent on particular programs.

Brown said he wants more of the state's dollars to benefit low-income and non-English-speaking students, who typically are more expensive to educate.

"The reality is, in some places students don't enjoy the same opportunities that people have in other places," the governor said in an interview. "This is a way to balance some of life's chances."

He would also scale back — and possibly eliminate — dozens of rules that districts must abide by to receive billions in state dollars. Some of those requirements, such as a mandate to limit class size, have been suspended amid Sacramento's recurrent budget problems but are set to resume by 2015.

Brown and his aides are keeping most details under wraps. But advisers say his proposals, part of the budget blueprint to be unveiled early this month, will amount to the most extensive changes in decades in the relationship between school districts and state government.

His intentions are already raising concerns among school administrators, district officials and labor unions. The governor postponed earlier plans to push for the changes when the discord threatened to distract from his campaign for higher taxes. Voters approved the tax hikes in November, averting billions of dollars in education cuts.

Now, the transformation of school funding is at the top of his agenda. He says his goal is more local control.

"What the state has done for 40 years is develop one new program after another to compensate for underperforming" schools, he said. "What we have now is command and control issuing from headquarters in Sacramento."

Scores of programs set up by state mandate — for smaller classes, bilingual education and summer school, for example — have their own pots of money sent from Sacramento to pay for them. ¿The Public Policy Institute of California found that nearly 40% of every dollar sent to schools from both the state and federal governments is earmarked for such a purpose.

The programs vary in size and scope: $4.5 million to meet the needs of Native American students, $10 million to improve school Internet access, more than $618 million set aside for school buses, etc.

According to Brown's Department of Finance, 56 such programs received a total of $11.8 billion in state funds last year. ¿The result, the governor says, is a bloated school bureaucracy that takes money away from core instruction.

"You have to have administrators at the state level, district level and at the school level who are engaged in making sure this money is used for what it's supposed to be used for," Brown said. "This constant articulation of rules is a world unto itself that is not directly supporting the teacher in the classroom."

But many of the programs are popular with parents and various interest groups and have staunch defenders in the Capitol. They say lifting restrictions on how schools spend their money could hurt struggling students.

In recent years, state lawmakers have offered districts some flexibility to cope with rounds of budget cuts. The results, some say, have not always been good, leading to larger classes and sharp reductions in programs for adults trying to earn a high school degree.

Since 2008, the average class size in kindergarten through third grade has grown from 20 to 23, among the largest in the nation, according to a study from the Public Policy Institute of California. During the same period, the average class size elsewhere in the country remained at around 15 students.

In addition, "since schools have been given greater flexibility, adult education ... has been decimated throughout the state," said Jeff Freitas, secretary-treasurer of the California Federation of Teachers. "You can't just give the locals carte blanche with the money."

Shifting money to poorer schools at the expense of wealthier ones is also certain to stir protest.

Under a similar proposal the governor floated last year, the Department of Finance estimated that Compton Unified schools would see an uptick of more than $4,700 per pupil by the 2017-18 school year. Manhattan Beach Unified would get a per-student increase of just $681.

Those who have met with Brown's top education aides expect the governor to propose a similar formula in January, asking districts to account for the expenditures to make sure the funds serve higher-needs students.

Adonai Smith, a lobbyist for the Assn. of California School Administrators, said his members would not support a plan that amounts to a "redistribution of resources."

The governor says that even if funding is tweaked to favor more poor students and English learners, all schools will receive more money now that state revenue is on the uptick.

"I want to align more closely the money schools receive with the problems that teachers encounter," Brown said. "When somebody's teaching in Compton, it's a much bigger challenge than teaching in Beverly Hills."

Divers Could Become Real-Life Aquamen if This Pentagon Project Works

Even casual divers know that diving too deep, or surfacing too quickly, can cause a host of complications from sickness to seizures and even sudden death. Now the Pentagon’s scientists want to build gear that can turn commandos into Aquaman, allowing them to plunge into the deeps without having to worry as much about getting ill. (Orange and green tights sold separately.)

According to a list of research proposals from the U.S. military’s blue-sky researchers at Darpa, the agency is seeking “integrated microsystems” to detect and control “warfighter physiology for military diver operations.” Essentially it comes down to hooking divers up to sensors that can read both their bio-physical signs and the presence of gases like nitric oxide, which help prevent decompression sickness, commonly known as “the bends.” If those levels dip too low, the Darpa devices will send small amounts of the gases into divers’ lungs to help keep them swimming.

The agency doesn’t specify what exactly the machine will look like, as it’s still in the research stage, but the plan is to make it portable enough for a diver to carry, of course. Darpa also wants the gear for bomb-disposal units and “expanded special operations.”

For an understandable reason. Decompression sickness can be extremely painful, and potentially lethal to divers in both the civilian world and the military. When underwater, a diver breathing compressed air out of a tank normally absorbs the air into fatty body tissues instead of breathing it all out, which is normally safe. But ascending to the surface too fast after a deep dive can cause those gases to form into bubbles inside the body — imagine yourself as the equivalent of a soda bottle, shaken really fast. That causes the body’s nervous system to go haywire and the joints to freeze up as if they were paralyzed. And that’s in addition to oxygen toxicity, nitrogen narcosis and a nasty problem called high-pressure nervous syndrome. None of these things are very pleasant, let alone for those who make a career deactivating underwater mines.

To avoid these problems, Navy divers are trained in “breathing static gas mixtures at prescribed pressures and durations,” according to the Darpa solicitation, as well as training in practical measures to avoid them, like divers would normally do. But to go further, Darpa’s plan is to use sensors to read “pressure-related physiologic conditions” and provide “constant physiological feedback.”

Then, the system will administer small amounts of nitric oxide into the diver’s lungs, which may reduce the bubbles that cause the bends. To clear up any confusion, nitric oxide — which helps our cells communicate with each other – is a different chemical than nitrous oxide, which is popularly known as a dental anesthetic. Darpa has also experimented with nitric oxide to see if it can prevent hypoxia in aircraft pilots.

Darpa also wants the gear to include a tiny gas chromatograph, which is used to analyze the gases, and another tool called CMUTs, or “capacitive micro-machined ultrasonic transducer arrays.” Basically, handheld ultrasound probes used by doctors to monitor body organs. But Darpa hopes the CMUTs can detect when bubbles form inside the body.

Finally, the agency wants the system to be built tough, and protect a diver during an “extreme combat dive profile.” This means the gear will have to work with a diver while jumping out of an airplane at six miles up, free-falling to the ocean before deploying a parachute, and diving down to 200 feet below the surface. Once the diver is underwater, they’ll need to be able to stay down for at least two hours, then surface, and dive again, although at a higher depth and for shorter periods of time. Not only that, but the system will have to protect the diver after he or she is picked up in an “unpressurized aircraft” like a helicopter. The reason that’s important? Taking to the air after diving can lead to decompression sickness even if you were safe coming out of the water, since the diver’s body is now reacting to an environment with plunging air pressure.

But there are also some civilian applications, and Darpa wants the gear to work with “exploration and extraction of undersea oil, gas, and minerals.” So super-powered oil divers searching for resources — in addition to bomb-disposal experts and special operations troops? Alright then. But it’s not certain whether the Aquaman would approve, being an environmentalist and all.

LA photographer killed while shooting Bieber’s car

LOS ANGELES (AP) — Police say a paparazzo was hit by a car and killed after taking photos of Justin Bieber‘s white Ferrari on a Los Angeles street.

Los Angeles police Officer James Stoughton says the photographer, who was not identified, died at a hospital shortly after the crash Tuesday evening. Stoughton says Bieber was not in the Ferrari at the time.

The sports car was parked on the side of Sepulveda Boulevard near Getty Center Drive after a traffic stop. The photographer was struck as he walked across the boulevard after taking pictures.

Stoughton says no charges are expected to be filed against the motorist who hit the man.

A call to a spokesperson for the singer was not immediately returned Tuesday night.

Scant Proof Is Found to Back Up Claims by Energy Drinks

Energy drinks are the fastest-growing part of the beverage industry, with sales in the United States reaching more than $10 billion in 2012 — more than Americans spent on iced tea or sports beverages like Gatorade.

Their rising popularity represents a generational shift in what people drink, and reflects a successful campaign to convince consumers, particularly teenagers, that the drinks provide a mental and physical edge.

The drinks are now under scrutiny by the Food and Drug Administration after reports of deaths and serious injuries that may be linked to their high caffeine levels. But however that review ends, one thing is clear, interviews with researchers and a review of scientific studies show: the energy drink industry is based on a brew of ingredients that, apart from caffeine, have little, if any benefit for consumers.

“If you had a cup of coffee you are going to affect metabolism in the same way,” said Dr. Robert W. Pettitt, an associate professor at Minnesota State University in Mankato, who has studied the drinks.

Energy drink companies have promoted their products not as caffeine-fueled concoctions but as specially engineered blends that provide something more. For example, producers claim that “Red Bull gives you wings,” that Rockstar Energy is “scientifically formulated” and Monster Energy is a “killer energy brew.” Representative Edward J. Markey of Massachusetts, a Democrat, has asked the government to investigate the industry’s marketing claims.

Promoting a message beyond caffeine has enabled the beverage makers to charge premium prices. A 16-ounce energy drink that sells for $2.99 a can contains about the same amount of caffeine as a tablet of NoDoz that costs 30 cents. Even Starbucks coffee is cheap by comparison; a 12-ounce cup that costs $1.85 has even more caffeine.

As with earlier elixirs, a dearth of evidence underlies such claims. Only a few human studies of energy drinks or the ingredients in them have been performed and they point to a similar conclusion, researchers say — that the beverages are mainly about caffeine.

Caffeine is called the world’s most widely used drug. A stimulant, it increases alertness, awareness and, if taken at the right time, improves athletic performance, studies show. Energy drink users feel its kick faster because the beverages are typically swallowed quickly or are sold as concentrates.

“These are caffeine delivery systems,” said Dr. Roland Griffiths, a researcher at Johns Hopkins University who has studied energy drinks. “They don’t want to say this is equivalent to a NoDoz because that is not a very sexy sales message.”

A scientist at the University of Wisconsin became puzzled as he researched an ingredient used in energy drinks like Red Bull, 5-Hour Energy and Monster Energy. The researcher, Dr. Craig A. Goodman, could not find any trials in humans of the additive, a substance with the tongue-twisting name of glucuronolactone that is related to glucose, a sugar. But Dr. Goodman, who had studied other energy drink ingredients, eventually found two 40-year-old studies from Japan that had examined it.

In the experiments, scientists injected large doses of the substance into laboratory rats. Afterward, the rats swam better. “I have no idea what it does in energy drinks,” Dr. Goodman said.

Energy drink manufacturers say it is their proprietary formulas, rather than specific ingredients, that provide users with physical and mental benefits. But that has not prevented them from implying otherwise.

Consider the case of taurine, an additive used in most energy products.

On its Web site, the producer of Red Bull, for example, states that “more than 2,500 reports have been published about taurine and its physiological effects,” including acting as a “detoxifying agent.” In addition, that company, Red Bull of Austria, points to a 2009 safety study by a European regulatory group that gave it a clean bill of health.

But Red Bull’s Web site does not mention reports by that same group, the European Food Safety Authority, which concluded that claims about the benefits in energy drinks lacked scientific support. Based on those findings, the European Commission has refused to approve claims that taurine helps maintain mental function and heart health and reduces muscle fatigue.

Taurine, an amino acidlike substance that got its name because it was first found in the bile of bulls, does play a role in bodily functions, and recent research suggests it might help prevent heart attacks in women with high cholesterol. However, most people get more than adequate amounts from foods like meat, experts said. And researchers added that those with heart problems who may need supplements would find far better sources than energy drinks.

Used to Hardship, Latvia Accepts Austerity, and Its Pain Eases

RIGA, Latvia — When a credit-fueled economic boom turned to bust in this tiny Baltic nation in 2008, Didzis Krumins, who ran a small architectural company, fired his staff one by one and then shut down the business. He watched in dismay as Latvia’s misery deepened under a harsh austerity drive that scythed wages, jobs and state financing for schools and hospitals.

But instead of taking to the streets to protest the cuts, Mr. Krumins, whose newborn child, in the meantime, needed major surgery, bought a tractor and began hauling wood to heating plants that needed fuel. Then, as Latvia’s economy began to pull out of its nose-dive, he returned to architecture and today employs 15 people — five more than he had before. “We have a different mentality here,” he said.

Latvia, feted by fans of austerity as the country-that-can and an example for countries like Greece that can’t, has provided a rare boost to champions of the proposition that pain pays.

Hardship has long been common here — and still is. But in just four years, the country has gone from the European Union’s worst economic disaster zone to a model of what the International Monetary Fund hails as the healing properties of deep budget cuts. Latvia’s economy, after shriveling by more than 20 percent from its peak, grew by about 5 percent last year, making it the best performer in the 27-nation European Union. Its budget deficit is down sharply and exports are soaring.

“We are here to celebrate your achievements,” Christine Lagarde, the chief of the International Monetary Fund, told a conference in Riga, the capital, this past summer. The fund, which along with the European Union financed a bailout of 7.5 billion euros for the country at the end of 2008, is “proud to have been part of Latvia’s success story,” she said.

When Latvia’s economy first crumbled, it wrestled with many of the same problems faced since by other troubled European nations: a growing hole in government finances, a banking crisis, falling competitiveness and big debts — though most of these were private rather than public as in Greece.

Now its abrupt turn for the better has put a spotlight on a ticklish question for those who look to orthodox economics for a solution to Europe’s wider economic woes: Instead of obeying any universal laws of economic gravity, do different people respond differently to the same forces?

Latvian businessmen applaud the government’s approach but doubt it would work elsewhere.

“Economics is not a science. Most of it is in people’s heads,” said Normunds Bergs, chief executive of SAF Tehnika, a manufacturer that cut management salaries by 30 percent. “Science says that water starts to boil at 100 degrees Celsius; there is no such predictability in economics.”

In Greece and Spain, cuts in salaries, jobs and state services have pushed tempers beyond the boiling point, with angry citizens staging frequent protests and strikes. Britain, Portugal, Italy and also Latvia’s neighbor Lithuania, meanwhile, have bubbled with discontent over austerity.

But in Latvia, where the government laid off a third of its civil servants, slashed wages for the rest and sharply reduced support for hospitals, people mostly accepted the bitter medicine. Prime Minister Valdis Dombrovskis, who presided over the austerity, was re-elected, not thrown out of office, as many of his counterparts elsewhere have been.

The cuts calmed fears on financial markets that the country was about to go bankrupt, and this meant that the government and private companies could again get the loans they needed to stay afloat. At the same time, private businesses followed the government in slashing wages, which made the country’s labor force more competitive by reducing the prices of its goods. As exports grew, companies began to rehire workers.

Economic gains have still left 30.9 percent of Latvia’s population “severely materially deprived,” according to 2011 data released in December by Eurostat, the European Union’s statistics agency, second only to Bulgaria. Unemployment has fallen from more than 20 percent in early 2010, but was still 14.2 percent in the third quarter of 2012, according to Eurostat, and closer to 17 percent if “discouraged workers” are included. This is far below the more than 25 percent jobless rate in Greece and Spain but a serious problem nonetheless.

This article has been revised to reflect the following correction:

Correction: January 2, 2013

An earlier version of this article misstated the amount of a bailout given to Latvia in 2008. It was 7.5 billion euros, not $7.5 billion.

Ruling over bumper-car injury supports amusement park

SAN FRANCISCO — The California Supreme Court, protecting providers of risky recreational activities from lawsuits, decided Monday that bumper car riders may not sue amusement parks over injuries stemming from the inherent nature of the attraction.

The 6-1 decision may be cited to curb liability for a wide variety of activities — such as jet skiing, ice skating and even participating in a fitness class, lawyers in the case said.

"This is a victory for anyone who likes fun and risk activities," said Jeffrey M. Lenkov, an attorney for Great America, which won the case.

But Mark D. Rosenberg, who represented a woman injured in a bumper car at the Bay Area amusement park, said the decision was bad for consumers.

"Patrons are less safe today than they were yesterday," Rosenberg said.

The ruling came in a lawsuit by Smriti Nalwa, who fractured her wrist in 2005 while riding in a bumper car with her 9-year-old son and being involved in a head-on collision. Rosenberg said Great America had told ride operators not to allow head-on collisions, but failed to ask patrons to avoid them.

The court said Nalwa's injury was caused by a collision with another bumper car, a normal part of the ride. To reduce all risk of injury, the ride would have to be scrapped or completely reconfigured, the court said.

"A small degree of risk inevitably accompanies the thrill of speeding through curves and loops, defying gravity or, in bumper cars, engaging in the mock violence of low-speed collisions," Justice Kathryn Mickle Werdegar wrote for the majority. "Those who voluntarily join in these activities also voluntarily take on their minor inherent risks."

Monday's decision extended a legal doctrine that has limited liability for risky sports, such as football, to now include recreational activities.

"Where the doctrine applies to a recreational activity," Werdegar wrote, "operators, instructors and participants …owe other participants only the duty not to act so as to increase the risk of injury over that inherent in the activity."

Amusement parks will continue to be required to use the utmost care on thrill rides such as roller coasters, where riders surrender control to the operator. But on attractions where riders have some control, the parks can be held liable only if their conduct unreasonably raised the dangers.

"Low-speed collisions between the padded, independently operated cars are inherent in — are the whole point of — a bumper car ride," Werdegar wrote.

Parks that fail to provide routine safety measures such as seat belts, adequate bumpers and speed controls might be held liable for an injury, but operators should not be expected to restrict where a bumper car is bumped, the court said.

The justices noted that the state inspected the Great America rides annually, and the maintenance and safety staff checked on the bumper cars the day Nalwa broke her wrist. The ride was functioning normally.

Reports showed that bumper car riders at the park suffered 55 injuries — including bruises, cuts, scrapes and strains — in 2004 and 2005, but Nalwa's injury was the only fracture. Nalwa said her wrist snapped when she tried to brace herself by putting her hand on the dashboard.

Rosenberg said the injury stemmed from the head-on collision. He said the company had configured bumper rides in other parks to avoid such collisions and made the Santa Clara ride uni-directional after the lawsuit was filed.

Justice Joyce L. Kennard dissented, complaining that the decision would saddle trial judges "with the unenviable task of determining the risks of harm that are inherent in a particular recreational activity."

"Whether the plaintiff knowingly assumed the risk of injury no longer matters," Kennard said.

The Future Is Now: What We Imagined for 2013 — 10 Years Ago

Predicting the future is hard, but that doesn’t stop us from trying. We’re Wired, after all.

Ten years ago, we boldly declared that we’d be living with phones on our wrists, data-driven goggles on our eyes and gadgets that would safety-test our food for us. Turns out, a lot of the things Sonia Zjawinski conceptualized in our “Living in 2013” feature way back in 2003 were remarkably close to what we’ve seen. We even got the iPhone right (sort of).

And so, as we look back on life in 2013 circa 2003, we’re going to spin it forward once again to tell you what life will be like in 2023.

Predicted for 2003 (above):

Apple redefined the desktop, laptop, and MP3 player. The next insanely great thing: an LCD arm cuff that includes a PDA, wireless Internet, a mini iPod, and, of course, a phone. The iPhone bracelet's motion sensor allows you to scroll through apps and files with the flick of a wrist, its clasp holds a digicam for use during video calls, and its wireless ear clip lets you listen and speak to callers. And everything can be done via voice recognition or touchscreen. Talk about the right call. Illustration: Kenn Brown.

Delivered in 2013:

Hey, it turns out, Apple gave us an iPhone after all! We got the name right, and even seemed to know about FaceTime. But the form factor details? Not so much. While you can wear an iPod nano as a watch, or make a call with your iPhone, if you want the watch-plus-phone combination that we teased you with 10 years ago, for now you'll need to pick up a secondary gadget that can transmit to your phone, like this Pebble. Photo: Ariel Zambelich/Wired.

Looking ahead to 2023:

Here's the thing, the screen on a watch is simply too small to display lots of data. And as an input device? Forget it. Yet keeping your phone out of sight means you often can't interact with your data on the go. The obvious answer is a variable size display. Samsung has already demonstrated a pretty convincing foldable OLED display prototype. Given 10 more years, we can easily see one screen serving multiple purposes by taking on multiple form factors, depending on whether you wanted to simply glance at it to read a message, or unfold it to write your reply.

Concern over Oscar voting extends deadline

LOS ANGELES (AP) — Growing concern that problems with the new electronic Oscar voting system could lead to record-low turnout has prompted the motion picture academy to extend the deadline for members to vote for Oscar nominations.

But next week’s highly anticipated announcements looming, the extension is only for a day, until Friday. The Academy of Motion Picture Arts and Sciences said Monday any votes received after the new deadline will not be counted.

“By extending the voting deadline we are providing every opportunity available to make the transition to online balloting as smooth as possible,” said the academy’s chief operating officer, Ric Robertson, in a statement. “We’re grateful to our global membership for joining us in this process.”

Reports of difficulty accessing the Oscars’ first-ever online voting system and fears that it could be hacked have raised questions about balloting for the 85th annual contest. Earlier this year, the academy and its longtime accountants, PricewaterhouseCoopers, partnered with the electronic voting firm Everyone Counts Inc. to develop the system.

“There’s considerable concern from many members that voter participation will be at record lows this year because the people who wanted to take a chance on this new cutting-edge system are either giving up on it or worried they won’t be able to cast their votes,” said Scott Feinberg, awards analyst and blogger for The Hollywood Reporter.

In the past, Oscar voting has been compiled strictly through paper ballots sent through the mail. The new system allows members to choose between voting online or sticking with a traditional mail-in ballot.

Morgan Spurlock, the documentary filmmaker whose 2004 film “Super Size Me” was nominated for best documentary, posted on Twitter last week that he wasn’t able to log on to vote electronically and his ballot was instead mailed to him.

“The password they sent didn’t work for my log-in — and they couldn’t email me a new log-in, only snail mail,” tweeted the 42-year-old director.

The academy said it has made several voting resources available to members, including assisted voting stations in Los Angeles, New York and London, and a 24-hour support line.

A spokesman for Everyone Counts didn’t immediately respond to a request seeking comment.

Besides online voting, a retooled nomination period could also affect the competition.

Organizers moved up the unveiling of the Oscar nominations to Jan. 10. That change puts the announcement three days before Hollywood‘s second-biggest awards ceremony, the Hollywood Foreign Press Association‘s Golden Globes, which are scheduled for Jan. 13.

Oscar overseers originally said the switcheroo would give the academy’s nearly 6,000 members more time to see nominated films before the Feb. 24 awards ceremony, but Feinberg of The Hollywood Reporter noted that the change gave voters less time to see potential contenders during the first phase of voting, when members decide on nominees.

“If the turnout is lower among older members, more traditional Oscar contenders will probably receive fewer votes, and otherwise edgier films that appeal more to younger people could fare better,” said Feinberg. “Because of the way that best-picture voting works, it could increase the chances of a movie like ‘The Master’ or ‘Moonrise Kingdom’ getting in.”

Ultimately, because of the inherent secrecy involved in selecting Oscar winners, Feinberg said it will be impossible to know what affects — if any — this year’s voting changes have on the ceremony, where as many as 10 films could be vying for the best-picture award.

In Theory: Pill Could Join Arsenal Against Bedbugs

THE HYPOTHESIS

A common deworming drug can be used to kill bedbugs.

THE INVESTIGATOR

Dr. Johnathan M. Sheele, Eastern Virginia Medical School

It was a visit to a cousin in New York City two years ago that inspired Thang D. Tran, a medical student at Eastern Virginia Medical School, to volunteer to become a human booby trap in the war on bedbugs.

“She told me everyone in New York was scared of bedbugs,” he said of his cousin. So when Dr. Johnathan M. Sheele, an emergency medicine specialist at his school, asked for volunteers to test a new way of killing the pests, Mr. Tran raised his arm. Soon, it was covered with itchy welts.

Dr. Sheele’s study, released at a tropical medicine convention in November, unveiled a possible new superweapon against Cimex lectularius: a deworming pill.

You take the pill and go to bed — perchance even to sleep, if you can sleep knowing how patiently bedbugs wait in your walls or mattress, sniffing for the sweet stream of your exhaled carbon dioxide and for your warm skin to grow still. You let them bite you. And then — in a few days — they die.

The technique is known as xenointoxication, which sounds like intergalactic beer pong but in medical pathology is Greek for “poisoning the guest.” In Dr. Sheele’s study, over 60 percent of the bedbugs died after volunteers like Mr. Tran took a single pill. Bigger or more regular doses might improve the lethality.

And it’s not as if the drug is rare and dangerous. It’s already in thousands of American households: ivermectin, the active ingredient in the beef-flavored Heartgard Chewables that kill heartworm in dogs.

(For humans, the brand name is Stromectol, and it is available by prescription only, usually for travelers who pick up worms overseas, or toddlers who get them from playing in sandboxes used by dogs.)

Ivermectin is also very safe. Millions of doses have been given to African children to kill the worms that cause river blindness. Many Papua New Guineans get double doses to kill scabies. One early study of the drug found that up to 10 times the normal dose was safe.

Ivermectin attacks a type of “gated chloride channel” in the nerves of insects that does not exist in mammals.

Dr. Sheele is not advising bedbug-tormented Americans to start eating Fido’s worm tablets. With only four volunteers, his study was tiny and preliminary, he emphasized. Neither the Food and Drug Administration nor any medical society has approved using ivermectin this way, and no one yet knows what the ideal antibedbug dose is.

But ivermectin experts say his idea isn’t crazy.

“Maybe partially crazy,” said Dr. Peter J. Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine. “But not entirely crazy.”

Dr. Hotez’s hesitation is mostly that bedbugs, unlike body lice and worms, do not cause disease, so xenointoxication seems heavy-handed.

But many Americans, including many New Yorkers, are so terrified of the bugs that they have spent thousands of dollars fighting them, so ivermectin could be cost-effective.

Brian D. Foy, a virologist at Colorado State University’s veterinary school, has shown that it also kills mosquitoes, and so could be used against malaria. His initial reaction to using it against bedbugs was that he thought it would be easier to clean one’s house and throw out one’s mattress.

“But maybe that’s just my ignorance about bedbugs,” he admitted. “We don’t have them out here in Colorado.”

(Local news reports do not back him up on that.)

“Needless to say,” he correctly pointed out, “this isn’t going to solve the problem of bedbugs in hotel rooms.”

Dr. Sheele speculated that ivermectin might be best used in combination with current measures like pesticides, desiccant powders, mattress covers, heat treatment, steaming and vacuuming. While it might not work alone, it could give exterminators a head start.

Dr. Frank O. Richards Jr., a parasitologist at the Carter Center in Atlanta who has spent years running programs in Africa and Asia that give out ivermectin donated by Merck to fight river blindness, said he was “excited to see how this plays out.” Americans might be initially squeamish about deworming pills, he said, but the country does have “a lot of worried rich people who don’t like bug bites.”

He has tracked women in his river-blindness programs who took ivermectin before realizing they were pregnant, he said, “and all their babies were cool.”Nonetheless, he said, even though one 2002 study found a huge dose to be safe, which theoretically means that multiple small ones also would be, “as a physician, I’d be very concerned about an off-label use like that.”

“If I gave that out, and something happened,” he continued, “I would not have a leg to stand on in court.”

Because each bug feeds only occasionally, he said, “I don’t buy that a week would do the trick. I think you’re going to need two, three, four weeks. And that’s concerning. We don’t have any toxicity data like that.”

Like Dr. Sheele, he favors more testing of multiple doses.

Ivermectin is not cheap. In the United States, a typical adult dose of Stromectol is about $40, and no generic version is sold legally. A year’s supply of Heartgard for a big dog can cost more than $100.

But, Dr. Sheele said, that pales beside the price of multiple visits by a team of exterminators.

He got interested in bedbugs, he said, because they plagued so many of his Norfolk, Va., emergency room patients.

“I even had one patient come in with a baggie full of them,” he said. “As a physician, there’s nothing you can do for them except give them Benadryl and steroids for the itching.”

He knew about ivermectin’s power to kill skin parasites because he had done a fellowship in international emergency medicine, he said.

His school provided financing but was nervous about letting him officially import bedbugs to campus, so he had to borrow the lab of a tick researcher at Old Dominion University. (Mr. Tran remembers it as humid and redolent of lab rats.)

Eastern Virginia Medical School also wanted animal studies before he recruited medical students, so he dosed mice first; in that case, 86 percent of the bedbugs died.

Now he hopes to find support for a full-fledged clinical trial.

And he is working on a new project: If xenointoxication kills bedbugs, he surmised, how about ticks?

The parasite-host relationship isn’t as predictable as it is between bedbugs and their dinner. But the stakes are higher, since ticks carry serious diseases like Lyme and babesiosis.

“It could be interesting for people who have to spend a lot of time in the woods — like soldiers,” he said.

Meanwhile, Mr. Tran and An Teng, another medical student and study participant, are enjoying their new notoriety.

“My friends were completely grossed out that I let myself be bitten,” said Mr. Tran, whose rash from the bites lasted for a month. “But working on something so relevant to society caught my attention.”

Senate Passes Tax Increases on Wealthy Americans

Senator Mitch McConnell, the Republican leader, departed early Tuesday after the vote.

WASHINGTON – The Senate, in a pre-dawn vote two hours after the deadline passed to avert automatic tax increases, overwhelmingly approved legislation Tuesday that would allow tax rates to rise only on affluent Americans while temporarily suspending sweeping, across-the-board spending cuts.

The deal, worked out in furious negotiations between Vice President Joseph R. Biden Jr. and the Republican Senate leader, Mitch McConnell, passed 89-8, with just three Democrats and five Republicans voting no. Although it lost the support of some of the Senate’s most conservative members, the broad coalition that pushed the accord across the finish line could portend swift House passage as early as New Year’s Day.

Quick passage before the markets reopen Wednesday would likely negate any economic damage from Tuesday’s breach of the so-called “fiscal cliff” and largely spare the nation’s economy from the one-two punch of large tax increases and across-the-board military and domestic spending cuts in the New Year.

“This shouldn’t be the model for how to do things around here,” Senator McConnell said just after 1:30 a.m. “But I think we can say we’ve done some good for the country.”

“You surely shouldn’t predict how the House is going to vote,” Mr. Biden said late New Year’s Eve after meeting with leery Senate Democrats to sell the accord. “But I feel very, very good.”

The eight senators who voted no included Marco Rubio, Republican of Florida and a potential presidential candidate in 2016, two of the Senate’s most ardent small-government Republicans, Rand Paul of Kentucky and Mike Lee of Utah, and Senator Charles E. Grassley, who as a former Finance Committee chairman helped secure passage of the Bush-era tax cuts, then opposed making almost all of them permanent on Tuesday. Two moderate Democrats, Tom Carper of Delaware and Michael Bennet of Colorado, also voted no, as did the liberal Democrat Tom Harkin, who said the White House had given away too much in the compromise. Senator Richard Shelby, Republican of Alabama, also voted no.

The House Speaker, John A. Boehner, and the Republican House leadership said the House would “honor its commitment to consider the Senate agreement.” But, they added, “decisions about whether the House will seek to accept or promptly amend the measure will not be made until House members – and the American people – have been able to review the legislation.”

Even with that cautious assessment, Republican House aides said a vote Tuesday is possible.

Under the agreement, tax rates would jump to 39.6 percent from 35 percent for individual incomes over $400,000 and couples over $450,000, while tax deductions and credits would start phasing out on incomes as low as $250,000, a clear victory for President Obama, who ran for re-election vowing to impose taxes on the wealthy.

Just after the vote, Mr. Obama called for quick House passage of the legislation.

“While neither Democrats nor Republicans got everything they wanted, this agreement is the right thing to do for our country and the House should pass it without delay,” he said.

 Democrats also secured a full year’s extension of unemployment insurance without strings attached and without offsetting spending cuts, a $30 billion cost. But the two-percentage point cut to the payroll tax that the president secured in late 2010 lapsed at midnight and will not be renewed.

In one final piece of the puzzle, negotiators agreed to put off $110 billion in across-the-board cuts to military and domestic programs for two months while broader deficit reduction talks continue. Those cuts begin to go into force on Wednesday, and that deadline, too, might be missed before Congress approves the legislation.

To secure votes, Senator Harry Reid, the Senate Democratic leader, also told Democrats the legislation would cancel a pending congressional pay raise — putting opponents in the politically difficult position of supporting a raise — - and extend an expiring dairy policy that would have seen the price of milk double in some parts of the country.

The nature of the deal ensured that the running war between the White House and Congressional Republicans on spending and taxes would continue at least until the spring. Treasury Secretary Timothy F. Geithner formally notified Congress that the government reached its statutory borrowing limit on New Year’s Eve. Through some creative accounting tricks, the Treasury Department can put off action for perhaps two months, but Congress must act to keep the government from defaulting just when the “pause” on pending cuts is up. Then in late March, a law financing the government expires.
