Exploring the final frontier: Disease proposed as major barrier to Mars and beyond
New research published in the Journal of Leukocyte Biology suggests that prolific virulence and growth of bacteria, coupled with reduced production of antibodies could limit future space travel. view more (2009-10-30)
Trees facilitate wildfires as a way to protect their habitat
Fire is often thought of something that trees should be protected from, but a new study suggests that some trees may themselves contribute to the likelihood of wildfires in order to promote their own abundance at the expense of their competitors. view more (2009-10-29)
Oxidized form of a common vitamin may bring relief for ulcerative colitis
New research published in the Journal of Leukocyte Biology finds retinoic acid may alleviate ulcerative colitis and similar irritable bowel diseases. view more (2009-10-01)
Shedding light on cancer cells
Scientists label cells with coloured or glowing chemicals to observe how basic cellular activities differ between healthy and cancerous cells. Existing techniques for labelling cells are either too slow or too toxic to perform on live cells. view more (2009-09-25)
Scandinavians are descended from Stone Age immigrants
Today's Scandinavians are not descended from the people who came to Scandinavia at the conclusion of the last ice age but, apparently, from a population that arrived later, concurrently with the introduction of agriculture. view more (2009-09-25)
National new biology initiative offers potential for 'remarkable and far-reaching benefits'
A report released today by the National Research Council calls on the United States to launch a new multiagency, multiyear, and multidisciplinary initiative to capitalize on the extraordinary advances recently made in biology and to accelerate new breakthroughs that could solve some of society's most pressing problems -- particularly in the areas... view more...

Prodrug could help curb skin toxicity related to EGFR-inhibiting cancer drugs
There may be a way around the harsh skin toxicity associated with a widely used cancer drug, according to a study published online this week in Cancer Biology and Therapy by researchers from City of Hope and the Kimmel Cancer at Jefferson. view more (2009-09-02)
U of T scientists identify gene that has enabled water striders to glide across water
Water striders, the familiar semi-aquatic bugs gliding across the lake at the cottage, have a novel body form that allows them to walk on water. view more (2009-08-14)
Launch of the first standard graphical notation for biology
Researchers at the European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI) and their colleagues in 30 labs worldwide have released a new set of standards for graphically representing biological information - the biology equivalent of the circuit diagram in electronics. view more (2009-08-12)
Joint research into an enzyme that causes genetic diseases
Researchers from CIC bioGUNE's Structural Biology Unit and Columbia University (New York) have conducted a joint research project, published in the prestigious scientific journal Structure, to gain in-depth knowledge of the structure of pyruvate carboxylase when it is in solution (in the "natural" state). view more (2009-08-06)
Scientists isolate protein that may be 'boon' to medicine
Scientists at UC Santa Barbara have isolated a unique protein that appears to have a dual function and could lead to a "boon in medicine." view more (2009-08-05)
Algebra adds value to mathematical biology education
As mathematics continues to become an increasingly important component in undergraduate biology programs, a more comprehensive understanding of the use of algebraic models is needed by the next generation of biologists to facilitate new advances in the life sciences, according to researchers at Sweet Briar College and the Virginia Bioinformatics... view more...

Got zinc? New zinc research suggests novel therapeutic targets
Everyone knows that vitamins "from A to zinc" are important for good health. Now, a new research study in the August 2009 print issue of the Journal of Leukocyte Biology suggests that zinc may be pointing the way to new therapeutic targets for fighting infections. view more (2009-07-31)
Genetically engineered bacteria compute the route
US researchers have created 'bacterial computers' with the potential to solve complicated mathematics problems. view more (2009-07-24)
International research team seeks to unravel flatworm regeneration
Planarian flatworms are only a few millimeters up to a few centimeters in length, live in freshwater and are the object of intense research, because they possess the extraordinary ability to regenerate lost tissue with the help of their stem cells (neoblasts) and even grow an entirely new worm out of minute amputated body parts. view more (2009-07-21)
Hormone clue to root growth
Plant roots provide the crops we eat with water, nutrients and anchorage. Understanding how roots grow and how hormones control that growth is crucial to improving crop yields, which will be necessary to address food security and produce better biofuels. view more (2009-07-08)
Discovery of the cell's water gate may lead to new cancer drugs
The flow of water into and out from the cell may play a crucial role in several types of cancer. Scientists at the University of Gothenburg have now found the gate that regulates the flow of water into yeast cells. view more (2009-06-17)
Cancer: The cost of being smarter than chimps?
Are the cognitively superior brains of humans, in part, responsible for our higher rates of cancer? That's a question that has nagged at John McDonald, chair of Georgia Tech's School of Biology and chief research scientist at the Ovarian Cancer Institute, for a while. view more (2009-06-10)
How an enzyme tells stem cells which way to divide
Driving Miranda, a protein in fruit flies crucial to switch a stem cell's fate, is not as complex as biologists thought, according to University of Oregon biochemists. They've found that one enzyme (aPKC) stands alone and acts as a traffic cop that directs which roads daughter cells will take. view more (2009-05-14)
Just in time for spring: Scientists find the cellular on and off switch for allergies and asthma
If you're one of the millions who dread the spring allergy season, things are looking up. view more (2009-04-30)
