Drug from genetically engineered goats a first

You've heard of making cheese from goats' milk, but prescription drugs? In what would be a scientific first, an anti-clotting drug made from the milk of genetically engineered goats moved closer to government approval Wednesday after experts at the Food and Drug Administration reported that the medication works and its safety is acceptable.

This undated handout illustration provided by The Johns Hopkins University shows the massive 30-foot wingspan of the toothless pteranodon, left, was surpassed by that of Hatzegopteryx, right, at 40 feet or more. Pterosaurs, sometimes weighed more than 500 pounds, and yet they soared above the other dinosaurs. Experts couldn't figure out how  because no bird can get that big could get off the ground. A new study has figured out how they did it: By leaping into the air from all fours - unlike any other flyers in history (except the vampire bats).

How big Jurassic flying reptiles got off ground

The Jurassic version of jumbo jets - huge flying creatures weighing hundreds of pounds - is a mystery of dinosaur-era flight: How did something so big get off the ground? A Johns Hopkins University biologist thinks he has figured out the answer.

In this photo provided by the University of North Carolina at Chapel Hill School of Medicine, Shannon Eubanks, left, her new baby Kathleen Conley Eubanks, and husband Gaston Eubanks share a moment in the hospital in Chapel Hill, N.C. Tuesday Jan. 6, 2009. Eubanks waited until she reached the 39th week of her pregnancy to schedule a Caesarean section to deliver her daughter. A study in the Jan. 8 issue of the New England Journal of Medicine shows that babies have fewer health problems if planned C-sections are done during the week before the due date.

C-sections best for baby when close to due date

Babies do better after a scheduled Caesarean section if they're born no sooner than seven days before their due date, a new large study of U.S. births shows. Those delivered earlier had more complications, including breathing problems, even though they were full term, the researchers reported in Thursday's New England Journal of Medicine. Even just a few days made a difference, they said.

Mississippi has highest teen birth rate, CDC says

Mississippi now has the nation's highest teen birth rate, displacing Texas and New Mexico for that lamentable title, a new federal report says. Mississippi's rate was more than 60 percent higher than the national average in 2006, according to new state statistics released Wednesday by the U.S. Centers for Disease Control and Prevention. The teen birth rate for that year in Texas and New Mexico was more than 50 percent higher.

Sharon Pederson poses for a photograph at a friend's house in Petaluma, Calif., Monday, Jan. 5, 2009. Pederson is a study subject who got deep brain stimulation, or DBS, surgery for her Parkinson's disease. In DBS, a surgeon implants electrodes in the brain which are then connected to a pacemaker-like device that can be adjusted and turned off and on. The device sends tiny electrical pulses to the brain, disabling overactive nerve cells.

Brain pacemaker helps Parkinson's, but with risks

Parkinson's sufferers who had electrodes implanted in their brains improved substantially more than those who took only medicine, according to the biggest test yet of deep brain stimulation. The study, which followed patients for six months, offers the most hopeful news to date for Parkinson's sufferers. The new technique reduced tremors, rigidity and flailing of the limbs and allowed people to move freely for nearly five extra hours a day.

A new study published in the Dec. 29, 2008 issue of Marine Mammal Science says pygmy killer whales living off Hawaii stay close to the islands, and don't swim out to the open ocean.  Scientists estimate there are less than 200 individual pygmy killer whales in Hawaiian waters.  The small numbers make the population more vulnerable to harmful human behavior than other whale populations.

Study: Hawaii's pygmy killer whales stay close

Smoking ban leads to major drop in heart attacks

A smoking ban in one Colorado city led to a dramatic drop in heart attack hospitalizations within three years, a sign of just how serious a health threat secondhand smoke is, government researchers said Wednesday. The study, the longest-running of its kind, showed the rate of hospitalized cases dropped 41 percent in the three years after the ban of workplace smoking in Pueblo, Colo., took effect. There was no such drop in two neighboring areas, and researchers believe it's a clear sign the ban was responsible.

New NASA report details final minutes of Columbia

When the first of many loud alarms sounded on the space shuttle Columbia, the seven astronauts had about a minute to live, though they didn't know it. The pilot, William McCool, pushed several buttons trying to right the ship as it tumbled out of control. He didn't know it was futile. Most of the crew were following NASA procedures, spending more time preparing the shuttle than themselves for the return to Earth.

Columbia was destroyed on February 1, 2003, on its return to Earth because of a hole in its wing that allowed in superhot atmospheric gases. The hole was caused by a piece of foam insulation that struck the spacecraft days earlier when it was launched.

Scientists eye unusual swarm of Yellowstone quakes
