Polarized light pollution leads animals astray
Human-made light sources can alter natural light cycles, causing animals that rely on light cues to make mistakes when moving through their environment.   view more (2009-01-07)

Biomedical researchers create artificial human bone marrow in a test tube
Artificial bone marrow that can continuously make red and white blood cells has been created in a University of Michigan lab.    view more (2008-12-23)

Model unravels rules that govern how genes are switched on and off
For years, scientists have struggled to decipher the genetic instruction book that details where and when the 20,000 genes in a human cell will be turned on or off. Different genes operate in each cell type at different times, and this careful orchestration is what ultimately distinguishes a brain... view more (2008-12-05)

Light pollution offers new global measure of coral reef health
We've all seen the satellite images of Earth at night--the bright blobs and shining webs that tell the story of humanity's endless sprawl.   view more (2008-11-25)

First live rhinoceros birth from frozen-thawed semen
There may be less than 20,000 rhinoceros in the world, with one species perhaps already extinct and another with possibly only four animals remaining in the wild.   view more (2008-11-13)

NC State finds new nanomaterial could be breakthrough for implantable medical devices
A team of researchers led by North Carolina State University has made a breakthrough that could lead to new dialysis devices and a host of other revolutionary medical implants.   view more (2008-11-11)

Extreme weather postpones the flowering time of plants
Extreme weather events have a greater effect on flora than previously presumed. A one-month drought postpones the time of flowering of grassland and heathland plants in Central Europe by an average of 4 days.   view more (2008-11-06)

A double-barreled immune cell approach for neuroblastoma
Adding an artificial tumor-specific receptor to immune system cells called T-lymphocytes that target a particular virus extended and improved the cells' ability to fight a form of childhood cancer called neuroblastoma, said researchers form Baylor College of Medicine and Texas Children's Hospital... view more (2008-11-03)

Scientists identify cell changes leading to impaired 'artificial kidney' function
Molecular targets identified by a Spanish research team may hold the key to freedom for some sufferers of kidney disease. A new study published in Disease Models & Mechanisms (DMM), dmm.biologists.org, reveals the cellular signals which cause one treatment for kidney failure to lose its... view more (2008-10-28)

Sensitive laser instrument could aid search for life on Mars
Minuscule traces of cells can be detected in a mineral likely present on Mars, a new study shows. The results, obtained using a technique developed at the U.S. Department of Energy's Idaho National Laboratory, could help mission scientists choose Martian surface samples with the most promise for... view more (2008-10-16)

Researchers design artificial cells that could power medical implants
Researchers at Yale University have created a blueprint for artificial cells that are more powerful and efficient than the natural cells they mimic and could one day be used to power tiny medical implants.   view more (2008-10-09)

Surface tension drives segregation within cell mixtures
What does a mixture of two different kinds of cells have in common with a mixture of oil and water? The same basic force causes both mixtures to separate into two distinct regions.   view more (2008-10-07)

Models of eel cells suggest electrifying possibilities
Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper by researchers at Yale University and the National Institute of Standards and Technology (NIST) takes it to a cellular level.   view more (2008-10-03)

Singing to females makes male birds' brains happy
The melodious singing of birds has been long appreciated by humans, and has often been thought to reflect a particularly positive emotional state of the singer.   view more (2008-10-03)

MIT paves way to 'artificial nose'
MIT biological engineers have found a way to mass-produce smell receptors in the laboratory, an advance that paves the way for "artificial noses" to be created and used in a variety of settings.   view more (2008-09-30)

Black-footed ferrets sired by males that died 8 years ago
Two black-footed ferrets at the Smithsonian's National Zoo have each given birth to a kit that was sired by males who died in 1999 and 2000   view more (2008-09-03)

Stanford's 'autonomous' helicopters teach themselves to fly
Stanford computer scientists have developed an artificial intelligence system that enables robotic helicopters to teach themselves to fly difficult stunts by watching other helicopters perform the same maneuvers.    view more (2008-09-03)

Biophysical method may help to recover hearing
Scientists based in Switzerland and South Africa have created a biophysical methodology that may help to overcome hearing deficits, and potentially remedy even substantial hearing loss. The authors propose a method of retuning functioning regions of the ear to recognize frequencies originally... view more (2008-08-29)

DOE official cites need for major breakthroughs to cope with climate change
Meeting the world's growing energy needs while responding to global warming during the 21st Century will be one of the biggest challenges humanity has ever faced, Raymond L. Orbach, Ph.D., the U.S. Department of Energy's Under Secretary for Science, says in the latest podcast in the American... view more (2008-08-27)

Future for clean energy lies in 'big bang' of evolution
Amid mounting agreement that future clean, "carbon-neutral", energy will rely on efficient conversion of the sun's light energy into fuels and electric power, attention is focusing on one of the most ancient groups of organism, the cyanobacteria.   view more (2008-08-25)

Drinking water in Gaza Strip contaminated with high levels of nitrate
Palestinian and German scientists have recommended to the authorities in the Gaza Strip that they take immediate measures to combat excessive nitrate levels in the drinking water.   view more (2008-08-15)

Licking your wounds: Scientists isolate compound in human saliva that speeds wound healing
A report by scientists from The Netherlands published online in The FASEB Journal (http://www.fasebj.org) identifies a compound in human saliva that greatly speeds wound healing.   view more (2008-07-24)

Bovine tuberculosis in wildlife threatens endangered lynx and cattle health
In an epidemiological survey of Spain's Doñana National Park, the findings of which are published on July 23 in the journal PLoS ONE, Christian Gortázar and colleagues studied the prevalence of bovine tuberculosis (bovine TB) infection among populations of wild boar, red deer and... view more (2008-07-23)

Bees go 'off-color' when they are sickly
Bumble-bees go 'off colour' and can't remember which flowers have the most nectar when they are feeling under the weather, a new study from the University of Leicester reveals.   view more (2008-07-16)
