Bad cholesterol: Genes make the difference
No matter what people's lifestyles, genes play an overriding role in cholesterol response, according to a new study of identical male twins -- one of each pair a long distance runner, the other a comparative couch potato -- conducted by researchers at the Department of Energy's Lawrence Berkeley National Laboratory and the Children's Hospital Oakland (California) Research Institute.

Scientists get a real 'rise' out of breakthroughs in how we understand changes in sea level
For the first time, researchers have the tools and expertise to understand the rate at which sea level is changing and the mechanisms that drive that change.

Mood lighting: Penn researchers determine role of serotonin in modulating circadian rhythm
Researchers at the University of Pennsylvania School of Medicine have determined how serotonin decreases the body's sensitivity to light and that exposure to constant darkness leads to a decrease in serotonin levels in the brain of fruit flies.

Álvaro Corral, a physicist at the Universitat Autònoma de Barcelona, has discovered that the structure of the time interval between successive earthquakes is similar to the spatial structure of physics systems in the

New study: Many local health directors unsure of authority to curtail smoking
Local health department directors across North Carolina are confused about state laws covering whether their facilities can be made smoke-free, but still strongly support such policies, according to a new University of North Carolina at Chapel Hill study.

Availability of vascular surgeons impacts amputation rate
Patients with peripheral arterial disease (PAD) are more likely to have a foot or leg amputated if they live in a region that has few vascular surgeons, according to a Rice University/Baylor College of Medicine study published in the July issue of the Journal of Vascular Surgery.

UIC researchers show how cancer-preventing foods work
Researchers at the University of Illinois at Chicago are unraveling the biochemical mechanism by which functional foods combat cancer.

Forecasters at the National Oceanic and Atmospheric Administration are predicting at least seven Atlantic hurricanes this year, with as many as five matching Ivan's destructive force.

African grey parrot is first bird to comprehend numerical concept akin to zero
A Brandeis Univesity researcher has shown that an African grey parrot with a walnut-sized brain understands a zero-like concept -- an abstract notion that humans don't typically understand until age 3 or 4, and that can significantly challenge learning-disabled children.

The Academy of Natural Sciences probes what's eating historic USS Monitor
The ironclad Civil War battleship USS Monitor rests in 240 feet of water off the North Carolina coast, but its ultimate fate may hinge on work done in a lab on the Benjamin Franklin Parkway.

Postpartum treatment key for depression: U of T study
The key to preventing postpartum depression may be individual support provided after birth by a health professional and tailored to a mother's needs, says a University of Toronto researcher.

NASA offers a real-time 3-D look at the inside of hurricanes
Seeing how rain falls from top to bottom and how heavy the rain falls throughout parts of a tropical cyclone is very important to hurricane forecasters.

USP Annual Scientific Meeting
The topics for this year's USP Annual Scientific Meeting include analytical validation and verification of compendial methods; biologics and biotechnology derived therapies; dietary supplements; excipients; making USP-NF work for you; and exhibit program and poster sessions.

For asthmatics and for anyone with respiratory problems, air pollution can significantly impair simple everyday activities.

New model for studying species distributions and the mid-domain effect developed
In order to address the current criticism of biodiversity gradients, new models are required that make explicit biological assumptions about how species' distributional limits are determined.

APS physics tip sheet #49
Highlights in this issue include a better time machine design; shaking to reduce friction; crack propagation in thin sheets; and the horizontal Brazil nut effect.

Early prostate cancer screening may reduce mortality rate
Early screening of prostate cancer in asymptomatic men may reduce their risk of death from metastatic prostate cancer by as much as 35 per cent, researchers from the University of Toronto have found.
