Flowering plants speed post-surgery recovery
Contact with nature has long been suspected to increase positive feelings, reduce stress, and provide distraction from the pain associated with recovery from surgery. Now, research has confirmed the beneficial effects of plants and flowers for patients recovering from abdominal surgery. view more (2008-12-29)
First large-scale HIV vaccine trial in South Africa opens
A large-scale clinical trial of a candidate HIV vaccine—which previously showed promise in smaller studies in the United States and elsewhere—has now opened in South Africa. view more (2007-02-09)
Metal Fibers Baked To Make Filters
In automotive catalytic converters and industrial exhaust gas filters, porous materials play a crucial role: they filter and break down hot waste gases. It is now possible to process virtually all metal alloys into fibers which can be used to make open-pored sintered materials. The requirements to be met by a coffee filter are simple: it must... view more... (2004-07-08)
Age-related difficulty recognizing words predicted by brain differences
Older adults may have difficulty understanding speech because of age-related changes in brain tissue, according to new research in the May 13 issue of The Journal of Neuroscience. view more (2009-05-13)
Study finds that even aloof husbands have lower testosterone levels than unmarried men
A fascinating new study is the first outside of North America to observe lower testosterone levels among married men. view more (2007-10-10)
Arctic pollution's surprising history
Scientists know that air pollution particles from mid-latitude cities migrate to the Arctic and form an ugly haze, but a new University of Utah study finds surprising evidence that polar explorers saw the same phenomenon as early as 1870. view more (2008-03-19)
Super sensitive gas detector goes down the nanotubes
When cells are under stress, they blow off steam by releasing minute amounts of nitrogen oxides and other toxic gases. view more (2009-01-14)
Researchers at University of Pennsylvania develop method for mass production of nanogap electrodes
Researchers at the University of Pennsylvania have developed a reliable, reproducible method for parallel fabrication of multiple nanogap electrodes, a development crucial to the creation of mass-produced nanoscale electronics. view more (2007-08-17)
Researchers find brain cell transplants help repair neural damage
A Swiss research team has found that using an animal's own brain cells (autologous transplant) to replace degenerated neurons in select brain areas of donor primates with simulated but asymptomatic Parkinson's disease and previously in a motor cortex lesion model, provides a degree of brain protection and may be useful in repairing brain lesions... view more...

Species unique to tidal marshes face threats
Tidal marshes cover only about 45,000 square kilometers worldwide-about the area of Denmark. In comparison with other habitats, tidal marshes support few nonaquatic vertebrate species, but their unique characteristics have led to the evolution of species and subspecies that are endemic (found nowhere else). view more (2006-08-01)
Study shows that prenatal exposure to alcohol may cause visual problems in infants
Fetal alcohol syndrome (FAS), a disorder that is indicated by distinct facial characteristics, growth retardation, and poor intellectual and attentional function, can occur when mothers drink alcohol heavily during pregnancy. view more (2005-10-20)
Turning huge data volumes into images
The first thing that a CAT scan of the human heart produces is simply data. Together with graphics hardware, the image processing software then constructs a picture that can be displayed on the computer. It's only natural that medical personnel, and even materials researchers, desire the most detailed images possible. But this always means... view more... (2003-02-20)
High-resolution CT scan modeling for creating facial implants aids in facial reconstruction surgery
A preliminary study suggests that high-resolution computed tomography (CT) modeling allows surgeons to custom-design acrylic implants prior to reconstructive surgery for patients with severe defects in their faces and eye cavities. view more (2006-11-21)
Galaxies are born inside dark matter clumps, Cornell study of Spitzer Space Telescope data shows
Try mixing caramel into vanilla ice cream - you will always end up with globs and swirls of caramel. Scientists are finding that galaxies may distribute themselves in similar ways throughout the universe and in places where there is lots of so-called dark matter. view more (2006-04-20)
Mapping the cosmic web of dark matter
What is Dark Matter and where is it found? These are two of the major mysteries in current studies of the Universe. Although the nature of this invisible material remains elusive, astronomers are beginning to produce detailed maps of the Cosmos, showing its location in relation to the ordinary matter that we can see in telescopes. One of the... view more... (2002-04-03)
Migrating songbirds learn survival tips on the fly
Migrating songbirds take their survival cues from local winged residents when flying through unfamiliar territory, a new Queen's University-led study shows. view more (2008-06-26)
Vision problems prompt older drivers to put down the keys
With 30 million drivers in the US aged 65 and over, we count on older Americans to recognize when they can no longer drive safely and decide that it's time to stay off the road. A new study finds that a decrease in vision function is a key factor in bringing about this decision. view more (2009-01-07)
Novel connection found between biological clock and cancer
Dartmouth Medical School geneticists have discovered that DNA damage resets the cellular circadian clock, suggesting links among circadian timing, the cycle of cell division, and the propensity for cancer. view more (2006-06-30)
New monkey discovered in Brazil
The Wildlife Conservation Society (WCS) announced today the discovery of a new monkey in a remote region of the Amazon in Brazil. view more (2009-07-08)
