We're off then: the evolution of bat migration
Not just birds, but also a few species of bats face a long journey every year. Researchers at Princeton University in the U.S. and at the Max Planck Institute for Ornithology in Radolfzell, Germany studied the migratory behaviour of the largest extant family of bats, the so-called "Vespertilionidae" with the help of mathematical models. view more (2009-11-24)
New discovery about the formation of new brain cells
The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells. view more (2009-11-24)
Anisakiasis hazard varies depending on the origin of the fish, according to a study
A research team of the University of Granada (Spain) has confirmed a higher presence of the parasite Anisakis spp in anchovies of the Atlantic South East coast and the Mediterranean North West coast, and they insist on freezing or cooking fish before consuming it. view more (2009-11-11)
Probiotic Found to Be Effective Treatment for Colitis In Mice
The probiotic, Bacillus polyfermenticus, can help mice recover from colitis, a new study has found. view more (2009-10-26)
Self-sacrifice among strangers has more to do with nurture than nature
Socially learned behavior and belief are much better candidates than genetics to explain the self-sacrificing behavior we see among strangers in societies, from soldiers to blood donors to those who contribute to food banks. view more (2009-10-13)
Panama butterfly migrations linked to El Niño, climate change
A high-speed chase across the Panama Canal in a Boston Whaler may sound like the beginning of another James Bond film-but the protagonist of this story brandishes a butterfly net and studies the effects of climate change on insect migrations at the Smithsonian Tropical Research Institute. view more (2009-10-06)
Juvenile bluefin tunas can dive to depths of more than 1000 meters
A bluefin tuna, tagged by AZTI-Tecnalia in August 2008, 15 miles to the north of Donostia-San Sebastián, was caught on 15 August of this year by a pleasure craft 88 miles north of Bakio. view more (2009-09-30)
Yale engineers track bacteria's kayak paddle-like motion for first time
Yale engineers have for the first time observed and tracked E. coli bacteria moving in a liquid medium with a motion similar to that of a kayak paddle. view more (2009-09-28)
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)
Salmon migration mystery explored on Idaho's Clearwater River
Temperature differences and slow-moving water at the confluence of the Clearwater and Snake rivers in Idaho might delay the migration of threatened juvenile salmon and allow them to grow larger before reaching the Pacific Ocean. view more (2009-09-18)
Reactive Oxygen's Role in Metastasis
Researchers at the Burnham Institute for Medical Research (Burnham) have discovered that reactive oxygen species, such as superoxide and hydrogen peroxide, play a key role in forming invadopodia, cellular protrusions implicated in cancer cell migration and tumor metastasis. view more (2009-09-16)
Making more efficient fuel cells
Bacteria that generate significant amounts of electricity could be used in microbial fuel cells to provide power in remote environments or to convert waste to electricity. view more (2009-09-08)
Researchers restore missing protein in rare genetic brain disorder
UCSF researchers have successfully used protease inhibitors to restore to normal levels a key protein involved in early brain development. Reduced levels of that protein have been shown to cause the rare brain disorder lissencephaly, which is characterized by brain malformations, seizures, severe mental retardation and very early death in human... view more...

NIH researchers identify key factor that stimulates brain cancer cells to spread
Researchers funded by the National Institutes of Health have found that the activity of a protein in brain cells helps stimulate the spread of an aggressive brain cancer called glioblastoma multiforme (GBM). view more (2009-08-19)
Computer scientists scale 'layer 2' data center networks to 100,000 ports and beyond
University of California, San Diego computer scientists have created software that they hope will lead to data centers that logically function as single, plug-and-play networks that will scale to the massive scale of modern data center networks. view more (2009-08-18)
Protein That Promotes Cancer Cell Growth Identified
Scientists at Burnham Institute for Medical Research (Burnham) have found that the Caspase-8 protein, long known to play a major role in promoting programmed cell death (apoptosis), helps relay signals that can cause cancer cells to proliferate, migrate and invade surrounding tissues. view more (2009-07-27)
The benefit of migration
Immigrants from the eight Central and Eastern European countries that joined the European Union in May 2004 are less likely to be claiming welfare benefits and less likely to be living in social housing than people born in the UK, according to a new paper from UCL. view more (2009-07-23)
A genetic basis for schizophrenia
Schizophrenia is a severely debilitating psychiatric disease that is thought to have its roots in the development of the nervous system; however, major breakthroughs linking its genetics to diagnosis, prognosis and treatment are still unrealized. view more (2009-07-22)
1 gene that contributes to breast cancer's aggressive behavior identified
Aggressive forms of cancer are often driven by the abnormal over-expression of cancer-promoting genes, also known as oncogenes. view more (2009-07-21)
St. Jude scientists discover a new mechanism controlling neuronal migration
The molecular machinery that helps brain cells migrate to their correct place in the developing brain has been identified by scientists at St. Jude Children's Research Hospital. view more (2009-07-16)
