Study: Europeans to suffer more ragweed with global warming
WASHINGTON (AP) — Global warming will bring much more sneezing and wheezing to Europe by mid-century, a new study says.
Sudden Infant Deaths Linked to Elevation
Babies who live at high elevations, those above 8,000 feet (2,438 meters), may face a slightly increased risk of Sudden Infant Death Syndrome, or SIDS, new research finds. "The absolute risk [of SIDS] remains very low, and … this is in no way a call to abandon residence [in] or visits to high-altitude" locations, said study researcher Dr. David Katz, a cardiologist at the University of Colorado Denver. But the research does suggest that low oxygen levels might play a role in SIDS — and that finding could hint at the cause of tragic, unexplained infant deaths.
How Does Salmonella Get into Sushi?
Raw tuna is the suspected source of a new outbreak of Salmonella, but how does tuna become contaminated with the bacteria in the first place? Experts say that the Salmonella probably wasn't living on the fish itself, but rather the tuna became contaminated at some point when the food was being handled. So far, at least 53 people in nine states have been sickened with a rare strain of Salmonella called Paratyphi B, according to the Centers for Disease Control and Prevention.
Memorial Day Meals: Expert Tips for Packing a Healthy Picnic
Memorial Day is considered the unofficial start of summer and perhaps the unofficial start of the outdoor eating season. Picnics are appealing, especially to people in colder climates who don't get many chances to eat outside in nice weather and enjoy a slow, relaxing meal, and they could also bring back childhood memories, said Sara Haas, a dietitian and chef in Chicago and a spokeswoman for the Academy of Nutrition and Dietetics. So pack up the red-checkered tablecloth, coolers and picnic basket, and bring along family and friends.
See Jupiter and the Moon in Night Sky Spectacle Tonight
There, about half way up from the south-southwest horizon to the overhead point, you’ll see an eye-catching sight for the Memorial Day weekend: Jupiter and the moon in a celestial display. Tonight, a rather wide crescent moon, 34-percent illuminated will be visible against the darkening sky and hovering about 3 degrees almost directly above this lunar sliver will be a brilliant silvery white "star." But this isn't a star, but the planet identified with the supreme sky-god, Jupiter. To judge how far apart Jupiter and the moon will appear in the sky, remember that your clenched fist, correctly held, will measure 10 degrees of the night sky.
Squid 'Sees' with Its Skin (No Eyes Needed)
Squid, cuttlefish and octopuses are masters of camouflage, capable of changing their skin colors and patterns in the blink of an eye. Two new studies, published this week in the Journal of Experimental Biology, find that cephalopod skin is chock-full of light-sensing cells typically found in eyes that help them "see." The cells likely send signals to alter skin coloration without involving the central nervous system, the researchers said. "It may be that the patterning is just generated directly on the spot, just by the cells," said Tom Cronin, a biologist at the University of Maryland and an author of one of the studies.
What Are Those Bright Spots on Ceres? Go Vote!
The puzzling white spots on the surface of the dwarf planet Ceres are definitely reflecting sunlight, scientists said, but the cause of the marks remains a mystery. The newest batch of images from the Dawn spacecraft, which began orbiting Ceres on March 6, was released May 15. With the release of these new images, NASA has asked the public to submit a guess for what is creating the spots: volcanos, geysers, rocks, ice, salt deposits, or "other." As of this writing, 37 percent of people who took NASA's poll for what the white spots might be said "other." Alien colonies, perhaps?
Prosecutors: Professor offered China data on US-made device

SpaceX capsule splashes down in Pacific with space station cargo
By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - A Space Exploration Technologies Dragon cargo capsule made a parachute splashdown into the Pacific Ocean on Thursday, wrapping up a five-week stay at the International Space Station. The capsule blasted off on April 14 aboard a Falcon 9 rocket from Cape Canaveral Air Force Station in Florida and arrived at the orbiting outpost three days later with more than 4,300 pounds (1,950 kg) of food, supplies and science experiments for the live-aboard crew. It was repacked with 3,100 pounds of science samples and other equipment and released back into orbit at 7:04 a.m. EDT (1104 GMT) on Thursday for a return trip to Earth, a NASA TV broadcast showed.
