Chilly times for Chinese dinosaurs: Abundance of feathered dinosaurs during temperate climate with harsh winters Posted: 11 Mar 2011 02:31 PM PST Dinosaurs did not always enjoy mild climates. New findings show that during part of the Early Cretaceous, north-east China had a temperate climate with harsh winters. They explain the abundance of feathered dinosaurs in fossil deposits of that period.

Radiation expert discusses Japan nuclear power plant concerns Posted: 11 Mar 2011 02:11 PM PST Following Friday's massive 8.9-magnitude earthquake that caused tsunamis and rocked the island nation of Japan, Japanese government officials announced a nuclear emergency after the quake caused a reactor cooling system malfunction at Fukushima No. 1 Nuclear Power Plant.

Near-real-time map of Japan quake aftershocks Posted: 11 Mar 2011 02:05 PM PST Researchers have created a near-real-time map of the aftershocks occurring globally following the 8.9 magnitude earthquake that rocked Japan Friday.

West Coast tsunami warnings shouldn’t lull Oregonians to sleep, expert says Posted: 11 Mar 2011 01:58 PM PST The massive earthquake that rocked Japan on March 11 and generated a tsunami that inundated coastal cities at that island nation triggered alerts around the world. The Oregon coast was no exception.

Pacific Northwest faces nearly identical risks to Japanese quake Posted: 11 Mar 2011 01:57 PM PST It's being called one of the largest recorded earthquakes in world history. Japan today is struggling with the aftermath of a massive 8.9 earthquake on a subduction zone, a short distance offshore, which unleashed a devastating tsunami that killed hundreds and has turned large parts of cities into rubble. The disaster is also a "wake up call" for the Pacific Northwest, a noted geologist says.

Mouse nose nerve cells mature after birth, allowing bonding, recognition with mother Posted: 11 Mar 2011 01:52 PM PST For rodent pups, bonding with mom isn't hard-wired in the womb. It develops over the first few weeks of life, which is achieved by their maturing sense of smell, possibly allowing these mammals a survival advantage by learning to identify mother, siblings, and home. Blending electrophysiological, biochemical and behavioral experiments, researchers demonstrated that neurons in the noses of mice mature after birth.

DCIS patients who get invasive breast cancer have higher mortality, study finds Posted: 11 Mar 2011 01:52 PM PST Women with ductal carcinoma in situ -- DCIS -- who later develop invasive breast cancer in the same breast are at higher risk of dying from breast cancer than those who do not develop invasive disease, according to a new study.

Giftedness linked to prenatal exposure of higher levels of testosterone Posted: 11 Mar 2011 12:35 PM PST A longstanding debate as to whether genius is a byproduct of good genes or good environment has an upstart challenger that may take the discussion in an entirely new direction. One researcher says being bright may be due to an excess level of a natural hormone.

How breast cell communities organize into breast tissue Posted: 11 Mar 2011 12:35 PM PST A new study has shown how communities of different types of breast cells self-organize into breast tissue. This work helps explain how the processes of stem cell differentiation and tissue architecture maintenance are coordinated, and might lead to a better understanding of what goes wrong in cancer.

Keys to long life? Not what you might expect Posted: 11 Mar 2011 12:35 PM PST Cheer up. Stop worrying. Don't work so hard. Good advice for a long life? In a groundbreaking study of personality as a predictor of longevity, researchers found just the opposite.

Dawn mission gets Vesta asteroid target practice Posted: 11 Mar 2011 11:08 AM PST In the lead-up to orbiting the second most massive body in the asteroid belt this coming July, planners of NASA's Dawn mission to the giant asteroid Vesta and scientists have been practicing mapping Vesta's surface, producing still images and a rotating animation that includes the scientists' best guess to date of what the surface might look like.

NASA study goes to Earth's core for climate insights Posted: 11 Mar 2011 11:07 AM PST The latest evidence of the dominant role humans play in changing Earth's climate comes not from observations of Earth's ocean, atmosphere or land surface, but from deep within its molten core.

NASA's Prolific Mars Reconnaissance Orbiter reaches five-year mark Posted: 11 Mar 2011 11:04 AM PST NASA's versatile Mars Reconnaissance Orbiter, which began orbiting Mars five years ago, has radically expanded our knowledge of the Red Planet and is now working overtime.

Color view from orbit shows Mars rover beside crater Posted: 11 Mar 2011 11:03 AM PST NASA's Mars Exploration Rover Opportunity has nearly completed its three-month examination of a crater informally named "Santa Maria," but before the rover resumes its overland trek, an orbiting camera has provided a color image of Opportunity beside Santa Maria.

A blood test for lung cancer? Posted: 11 Mar 2011 10:19 AM PST Researchers have discovered genes that increase not only one's risk of lung cancer, but perhaps one's urge to smoke as well. Now these researchers are working on developing a blood test for lung cancer.

Low cost solar cells: New European record in efficiency Posted: 11 Mar 2011 10:17 AM PST Scientists have developed an improved preparation process for kesterite solar cells, which resulted in a new European record efficiency of 6.1 percent.

Pushing HIV out the door: How host factors aid in the release of HIV particles Posted: 11 Mar 2011 10:17 AM PST New research shows how host enzymes contribute to the release of HIV particles from infected cells. With the aid of their new microscopy technique, they now aim to analyze the entire life cycle of the virus in unprecedented detail.

New view of human nerve cells opens door to potential drug targets Posted: 11 Mar 2011 10:17 AM PST Scientists have found a way to uncover potential drug targets that have so far remained hidden from researchers' view. By applying the new method to a type of nerve cell critical to regulating body temperature, the authors found more than 400 "receptors" (structures that bind other molecules, triggering some effect on the cell) responding to neurotransmitters, hormones, and other chemical signals. This represents 20 to 30 times more receptors than previous studies had identified.

Geologists in the UK trace readings from Japan earthquake Posted: 11 Mar 2011 10:17 AM PST Geologists in the UK have recorded the impact of today's major earthquake, off the coast of Japan, using sophisticated equipment. The magnitude 8.9 quake east of Honshu on March 11, 2011 was recorded on a SEIS-UK seismometer. It shows three traces that measure movement of Earth's surface in the vertical, north-south and east-west direction. SEIS-UK is part of the Natural Environment Research Council's Geophysical Equipment Facility.

Speed demon star creates a shock Posted: 11 Mar 2011 10:16 AM PST Just as some drivers obey the speed limit while others treat every road as if it were the Autobahn, some stars move through space faster than others. NASA's Wide-field Infrared Survey Explorer, or WISE, captured a new image of the star Alpha Camelopardalis speeding through the sky like a motorcyclist zipping through rush-hour traffic.

Thrill-seeking females work hard for their next fix, rat study suggests Posted: 11 Mar 2011 09:21 AM PST It seems that women become addicted to cocaine more easily than men and find it harder to give up. New research reinforces this position by showing that the motivation of female rats to work for cocaine is much higher than males.

Predicting future appearance: New computer-based technique ages photographic images of people's faces Posted: 11 Mar 2011 09:20 AM PST A graduate student has designed a promising computer program that could serve as a new tool in missing-child investigations and matters of national security. Khoa Luu has developed a more effective computer-based technique to age photographic images of people's faces -- an advance that could help to identify missing kids and criminals on the lam.

Seventy percent of prostate cancer patients on androgen-deprivation therapy gain significant weight in first year Posted: 11 Mar 2011 09:20 AM PST Seventy percent men who received androgen-deprivation therapy (ADT) after surgery to remove their prostate gland gained significant weight in the first year, putting on an average of 4.2 kilograms, a new study finds.

Contrary to popular belief, not all cases of chronic pancreatitis are alcohol-induced Posted: 11 Mar 2011 09:20 AM PST The relative rate of alcohol-related chronic pancreatitis is lower when compared to other causes, according to a new study. Patients with no identifiable cause for their disease as well as those with non-alcohol-related causes represent an unexpectedly large subgroup, particularly among women.

Nanoscale whiskers from sea creatures could grow human muscle tissue Posted: 11 Mar 2011 09:18 AM PST Minute whiskers of nanoscale dimensions taken from sea creatures could hold the key to creating working human muscle tissue, researchers say.

Monitoring blood for 'microparticles' useful in identifying earliest signs of emphysema Posted: 11 Mar 2011 09:18 AM PST Monitoring blood for tiny particles released by cells lining the lungs may help clinicians diagnose emphysema in its earliest stages, according to researchers. The particles, called endothelial microparticles, are shed during the disease process as tiny blood vessels in the lungs, called pulmonary capillaries, are injured and die.
