Farmed fish with parasites: impact on wild fish stocks
'Fish farming is often proposed as a solution to diminishing stocks of wild fish. Sadly, many parasites are threatening the future of aquaculture' [by depleting fish stocks], write Jo Cable and Phil Harris, of Cardiff and Nottingham Universities, in the August issue of Biologist. A wide range of invertebrates can live on, or in fish before they... view more... (2003-08-01)
Desertification: UN experts prescribe global policy overhaul to avoid looming mass migrations
Desertification, exacerbated by climate change, represents "the greatest environmental challenge of our times" and governments must overhaul policy approaches to the issue or face mass migrations of people driven from degraded homelands within a single generation, warns a new analysis from the United Nations University. view more (2007-06-28)
Team tracks antibiotic resistance from swine farms to groundwater
The routine use of antibiotics in swine production can have unintended consequences, with antibiotic resistance genes sometimes leaking from waste lagoons into groundwater. view more (2007-08-22)
Researchers block immune cell rush behind deadly sepsis
Researchers have found a way to block the ability of white blood cells to sprint toward the sites of infection when such speed worsens the damage done by sepsis, the often fatal, whole-body bacterial infection, according to a study published today in the journal Blood. view more (2009-02-25)
History of human cannibalism eats away at researchers
In a new study published by the journal Genome Research, a team of scientists reports that 'mad cow'-like diseases have not been a major force in human history, nor have been cannibalistic rituals that are known to be associated with disease transmission. view more (2006-01-04)
Older men more likely than women to die after pneumonia
Differing biological response to infection between men and women may explain higher death rates among older men who are hospitalized with community-acquired pneumonia (CAP). view more (2009-04-30)
Novel discovery of DCDC2 gene associated with dyslexia
Pediatric researchers at Yale School of Medicine have identified a gene on human chromosome 6 called DCDC2, which is linked to dyslexia, a reading disability affecting millions of children and adults. view more (2005-10-31)
Human culture subject to natural selection, Stanford study shows
The process of natural selection can act on human culture as well as on genes, a new study finds. view more (2008-02-19)
Gene study shows three distinct groups of chimpanzees
The largest study to date of genetic variation among chimpanzees has found that the traditional, geography-based sorting of chimps into three populations—western, central and eastern—is underpinned by significant genetic differences, two to three times greater than the variation between the most different human populations. view more (2007-04-23)
Newly identified biomarker detects and regulates spread of brain tumors
Researchers at Emory University's Winship Cancer Institute have identified a novel biomarker for brain tumors and have uncovered a potential role the marker may play when the tumor spreads or comes back after treatment. view more (2006-11-13)
Model identifies genes that induce normal skin cells to become abnormal
Northwestern University researchers have developed a novel, three-dimensional model that allows scientists to observe how interacting with the microenvironment of metastatic melanoma cells induces normal skin cells to become similar to aggressive cancer cells that migrate and spread throughout the body. view more (2005-11-15)
Ancient DNA traces the woolly mammoth's disappearance
Some ancient-DNA evidence has offered new clues to a very cold case: the disappearance of the last woolly mammoths, one of the most iconic of all Ice Age giants, according to a June 7th report published online in Current Biology, a publication of Cell Press. view more (2007-06-08)
EMBO supports restart of six female scientists at the bench
The first six fellows to benefit from the European Molecular Biology Organization's (EMBO) new restart fellowship scheme are preparing to start work in their laboratories. The selected researchers come from Germany, Hungary, the UK and Italy. They will restart their research careers on full-time EMBO fellowships that cover a two-year period.... view more...

Researchers find earliest evidence for modern human behavior in South Africa
Evidence of early humans living on the coast in South Africa, harvesting food from the sea, employing complex bladelet tools and using red pigments in symbolic behavior 164,000 years ago, far earlier than previously documented, is being reported in the Oct. 18 issue of the journal Nature. view more (2007-10-18)
UBC study establishes formula for predicting climate change impact on salmon stocks
University of British Columbia researchers have found a way to accurately predict the impact of climate change on imperilled Pacific salmon stocks that could result in better management strategies. view more (2008-11-13)
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)
Scientists determine geese involved in Hudson River plane crash were migratory
Scientists at the Smithsonian Institution examined the feather remains from the Jan. 15 US Airways Flight 1549 bird strike to determine not only the species, but also that the Canada geese involved were from a migratory, rather than resident, population. view more (2009-06-09)
Molecule prompts damaged heart cells to repair themselves after a heart attack
A protein that the heart produces during its early development reactivates the embryonic coronary developmental program and initiates migration of heart cells and blood vessel growth after a heart attack, researchers at UT Southwestern Medical Center have found. view more (2009-04-13)
Mountain caribou's ancient ancestry revealed
The declining mountain caribou populations of Canada's southern Rockies are a more distinct breed than scientists previously believed, according to a new study by University of Calgary researchers that is shedding light on the ancient ancestry of the mountain-dwelling herbivores. view more (2009-01-29)
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)
