For migrating sparrows, kids have a compass, but adults have the map
Even bird brains can get to know an entire continent -- but it takes them a year of migration to do so, suggests a Princeton research team. view more (2007-11-06)
Molecules can block breast cancer's ability to spread
Researchers have identified a specific group of microRNA molecules that are responsible for controlling genes that cause breast cancer metastasis. view more (2008-01-10)
Study shows how the zebrafish gets his stripe
Scientists have discovered how the zebrafish (Danio rerio) develops one of its four stripes of pigment cells. view more (2007-09-26)
A molecule that protects from neuronal disorders
Many neuronal disorders, including epilepsy, schizophrenia and lissencephaly - a form of mental retardation -, result from abnormal migration of nerve cells during the development of the brain. view more (2007-09-17)
Why do birds migrate?
Why do some birds fly thousands of miles back and forth between breeding and non-breeding areas every year whereas others never travel at all? view more (2007-03-02)
Stanford study uses genetic evidence to trace ancient African migration
Stanford University researchers peering at history's footprints on human DNA have found new evidence for how prehistoric people shared knowledge that advanced civilization. view more (2008-08-05)
Y chromosome study sheds light on Athapaskan migration to southwest US
A large-scale genetic study of native North Americans offers new insights into the migration of a small group of Athapaskan natives from their subarctic home in northwest North America to the southwestern United States. The migration, which left no known archaeological trace, is believed to have occurred about 500 years ago. view more (2008-07-16)
Everybody wins from short term eastern European migration
Despite current concerns in the UK about working conditions and breaches of safety standards in agriculture involving eastern European migrants, there is conclusive evidence that others in different occupations are benefiting from short term employment opportunities. As part of research funded by the Economic and Social Research Council, almost... view more... (2005-03-23)
Ultrasound affects embryonic mouse brain development
The prolonged and frequent use of ultrasound on pregnant mice causes brain abnormalities in the developing mouse fetus. view more (2006-08-08)
Texas A&M scientists say early Americans arrived earlier
A team led by two Texas A&M University anthropologists now believes the first Americans came to this country 1,000 to 2,000 years earlier than the 13,500 years ago previously thought, which could shift historic timelines. view more (2008-03-24)
Out of Africa-Bacteria, as well
When man made his way out of Africa some 60,000 years ago to populate the world, he was not alone: He was accompanied by the bacterium Helicobacter pylori, which causes gastritis in many people today. view more (2007-02-15)
Pig study forces rethink of Pacific colonisation
A survey of wild and domestic pigs has caused archaeologists to reconsider both the origins of the first Pacific colonists and the migration routes humans travelled to reach the remote Pacific. view more (2007-03-13)
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)
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)
Signatures of the first stars
A primitive star with extremely low iron content has been discovered by an international research team from Sweden, Japan, Germany, USA, Australia and Great Britain. The results are published in Nature online this week. view more (2005-04-15)
Light guides flight of migratory birds
Songbirds use multiple sources of directional cues to guide their seasonal migrations, including the Sun, star patterns, the earth's magnetic field, and sky polarized light patterns. view more (2006-08-11)
Researchers find new way to block destructive rush of immune cells
Researchers have found a way to selectively block the ability of white blood cells to "crawl" toward the sites of injury and infection when such mobility drives disease, according to a study published today in The Journal of Experimental Medicine. view more (2008-01-14)
Neurons find their place in the developing nervous system with the help of a sticky molecule
The brain, that exquisite network of billions of communicating cells, starts to take form with the genesis of nerve cells. Most newborn nerve cells, also called neurons, must travel from their birthplace to the position they will occupy in the adult brain. view more (2006-04-26)
Jefferson scientists show protein key to bladder cancer spread, potential drug target
By demonstrating that a protein - a growth factor called proepithelin - plays a crucial role in the spread of bladder cancer, scientists at Jefferson Medical College and Jefferson's Kimmel Cancer Center may have identified a potential target for drugs. view more (2006-07-17)
Tropical winter habitat drives natal dispersal of young migratory birds
A new study by scientists at the Migratory Bird Center at the Smithsonian's National Zoo shows that the factors determining where birds settle and nest in the first breeding season depends on the habitat they used during their first winter in the tropics. view more (2008-02-19)
