The ALPHA experiment at CERN last year reported trapping 38 antihydrogen atoms for 0.1 seconds each.

Columbia Engineering team makes major step in improving forecasts of weather extremes
Columbia Engineering, Geophysical Fluid Dynamics Laboratory and Rutgers University researchers have demonstrated that high evaporation increases the probability of afternoon rainfall in eastern US and Mexico.

Pregnant women can prevent excess weight gain with simple steps, study finds
A new study reports that a low-cost healthy lifestyle program, including self-weighing weekly or monthly, by pregnant women with pre-existing overweight can prevent them from gaining too much weight during early pregnancy.

Stem cell treatment may offer option for broken bones that don't heal
Researchers at the University of North Carolina at Chapel Hill School of Medicine have shown in an animal study that transplantation of adult stem cells enriched with a bone-regenerating hormone can help mend bone fractures that are not healing properly.

Stem cell treatment may become option to treat nonhealing bone fractures
Stem cell therapy enriched with a bone-regenerating hormone, insulin-like growth factor-I (IGF-I), can help mend broken bones in fractures that are not healing normally, a new animal study finds.

PARTNER shows similar 1-year survival for catheter-based AVR and open AVR in high-risk patients
Less invasive catheter-based aortic valve replacement and open valve-replacement surgery have a similar one-year survival for patients at high risk for surgery.

Astrophysicists use X-ray fingerprints to study eating habits of giant black holes
By studying the X-rays emitted when superheated gases plunge into distant and massive black holes, astrophysicists at the Georgia Institute of Technology have provided an important test of a long-standing theory that describes the extreme physics occurring when matter spirals into these massive objects.

11-year study reveals risk of major birth defects associated with 4 common epilepsy drugs at different doses
Use of four of the most commonly prescribed seizure-control drugs at the beginning of pregnancy is associated with a dose-dependent increased risk of major birth defects.

New solar system formation models indicate that Jupiter's foray robbed Mars of mass
Planetary scientists have long wondered why Mars is only about half the size and one-tenth the mass of Earth.

Cut down on 'carbs' to reduce body fat, study authors say
A modest reduction in consumption of carbohydrate foods may promote loss of deep belly fat, even with little or no change in weight, a new study finds.

Upping the anti
The ALPHA experiment at CERN, including key Canadian contributors, reports that it has succeeded in storing antimatter atoms for over 16 minutes.

Indiana University neuroscientists map a new target to wipe pain away
Researchers at the Indiana University School of Medicine have discovered a peptide that short circuits a pathway for chronic pain.

Anti-obesity vaccine reduces food consumption in animals
A new therapeutic vaccine to treat obesity by suppressing the appetite-stimulating hormone ghrelin decreases food intake and increases calorie burning in mice, a new study finds.

Early light refines the brain's circuitry for vision
Creatures are not born hardwired to see. Instead, they depend on electrical activity in the retina to refine the complex circuits that process visual information.

Mayo Clinic: Flaxseed no cure for hot flashes during breast cancer or menopause
Flaxseed provides no benefit in easing hot flashes among breast cancer patients and postmenopausal women, according to a Mayo Clinic and North Central Cancer Treatment Group study.

ALPHA stores antimatter atoms for over a quarter of an hour -- and still counting
Lawrence Berkeley National Laboratory physicists are key members of the international ALPHA Collaboration at CERN in Geneva, which has succeeded in storing a total of 309 antihydrogen atoms, some for as long as 1,000 seconds (almost 17 minutes) or even longer -- more than enough time to perform meaningful scientific experiments on confined anti-atoms.

Genetics of melanoma chemoresistance
Malignant melanoma is a highly aggressive and notoriously chemoresistant form of cancer.

New generation asthma drug could improve metabolism
Formoterol, a new generation asthma medication, shows great promise for improving fat and protein metabolism, say Australian researchers, who have tested this effect in a small sample of men.

Huge ancient language dictionary finished after 90 years
An ambitious project to identify, explain and provide citations for the words written in cuneiform on clay tablets and carved in stone by Babylonians, Assyrians and others in Mesopotamia between 2500 B.C. and A.D.

Group led by Hebrew University professor chosen as Israeli Center for Research Excellence
A research group led by a professor from the Hebrew University of Jerusalem Faculty of Medicine was announced this week as one of the first three centers chosen to be established in a new public initiative in Israel called the Centers for Research Excellence, known in brief as I-Core.

Weight loss after gastric bypass surgery reduces expression of Alzheimer's genes
Obesity is a risk factor for Alzheimer's disease, but weight loss due to bariatric surgery may reduce the risk of this common dementia, a new study suggests.

Athletic girls more likely to have impaired bone structure if menstrual cycle stops
Young female athletes who have stopped menstruating have a weakening in the quality of their bone structure that may predispose them to breaking a bone, despite getting plenty of weight-bearing exercise, a new study finds.

Targeted cancer therapy kills prostate tumor cells
A new targeted therapy for prostate cancer halts tumor growth in animals with advanced prostate cancer that is resistant to hormone therapy, a new study finds.

Hormone test predicts ovarian function after chemotherapy for breast cancer
A test that shows how many eggs a woman has in her ovaries may help young women with breast cancer know what their reproductive function will be after chemotherapy, a new study finds.

Elderly may be more likely to die if they have subclinical hyperthyroidism
A common hormone abnormality in older adults -- a mild form of overactive thyroid called subclinical hyperthyroidism -- is linked to a much higher risk of dying, a new study finds.

Carbon release to atmosphere 10 times faster than in the past
The rate of release of carbon into the atmosphere today is nearly 10 times as fast as during the Paleocene-Eocene Thermal Maximum (PETM), 55.9 million years ago, the best analog we have for current global warming, according to an international team of geologists.

Scientists use super microscope to pinpoint body's immunity 'switch'
Using the only microscope of its kind in Australia, medical scientists have been able for the first time to see the inner workings of T-cells, the front-line troops that alert our immune system to go on the defensive against germs and other invaders in our bloodstream.
