Researchers discover ancient origins of tuberculosis-causing bacteria
Researchers have long considered tuberculosis, a bacterial respiratory disease that kills 3 million people each year, a relatively recent human affliction. view more (2005-08-19)
Why wind turbines can mean death for bats
Power-generating wind turbines have long been recognized as a potentially life-threatening hazard for birds. But at most wind facilities, bats actually die in much greater numbers. view more (2008-08-26)
Salmon farms kill wild fish, study shows
New research confirms that sea lice from fish farms kill wild salmon. Up to 95 per cent of the wild juvenile salmon that migrate past fish farms die as a result of sea lice infestation from the farms. view more (2006-10-03)
Immigrant Sun: Our star could be far from where it started in Milky Way
A long-standing scientific belief holds that stars tend to hang out in the same general part of a galaxy where they originally formed. Some astrophysicists have recently questioned whether that is true, and now new simulations show that, at least in galaxies similar to our own Milky Way, stars such as the sun can migrate great distances. view more (2008-09-16)
Cellular cues identified for stroke recovery
When a stroke strikes, the supply of blood to the part of the brain affected is interrupted, starving it of oxygen. Brain cells can be seriously damaged or die, impairing local brain function. view more (2006-12-26)
REFUGEE SERIES - 50 YEARS ON (pp 1384, 1425-37, 1454)
Half a century after the adoption of the 1951 Convention relating to the Status of Refugees, THE LANCET is this week publishing a series of thought-provoking articles concerning the health and human rights of the world's population of displaced people. The series of essays discusses a wide range of refugee issues in both less-developed and... view more... (2001-05-03)
Acute pancreatitis and cholangitis: a complication caused by a migrated gastrostomy tube
Percutaneous endoscopic gastrostomy (PEG) is generally considered to be safe with a low rate of serious complications. However, dislocation of a gastrostomy tube can lead to serious complications. view more (2007-10-25)
A new tribe at the BA festival
A new tribe is emerging from Mexico's scorched earth. A team of geoarchaeologists working on a programme investigating human evolution have found skeletal remains in the desert of the Baja California Peninsula that give rise to new theories on the colonisation of the Americas. view more (2004-09-03)

Manatee Traveler in Northeastern Waters not Chessie
A West Indian manatee has been sighted in various waters of the northeastern United States in the last 5-6 weeks. It took in the sights along the Hudson River traveling up into Harlem, visited Cape Cod, Mass., and was most recently sighted in Warwick, Rhode Island, in Greenwich Bay. view more (2006-08-24)
Johns Hopkins scientists map brain area that may aid hunt for human brain stem cells
A study led by a Johns Hopkins neurosurgeon has provided the first comprehensive map of a part of the adult human brain containing astrocytes, cells known to produce growth factors critical to the regeneration of damaged neural tissue and that potentially serve as brain stem cells. view more (2006-02-17)
NASA study links Earth impacts to human-caused climate change
A new NASA-led study shows human-caused climate change has made an impact on a wide range of Earth's natural systems, including permafrost thawing, plants blooming earlier across Europe, and lakes declining in productivity in Africa. view more (2008-05-15)
Migration and Aids: social control, a brake on the spread of HIV in Senegal?
Ever since Aids appeared, migration has been thought to be a driving force behind the epidemic. The disease is often represented either as an "imported pathology", migrants being the disease (or at least risk), carriers or as a "pathology of adaptation". Migrants, mainly young men who move around to find work, are subjected to... view more... (2005-01-25)
Primate Bushmeat : Populations exposed to Simian Immunodeficiency Viruses
Both HIV-1 and HIV-2 are of zoonotic origin , and the closest simian relatives of HIV-1 and HIV-2 have been found in the common chimpanzee (Pan troglodytes) and the sooty mangabey (Cercocebus atys) respectively. Given that humans come in frequent contact with primates in many parts of subsaharan Africa, particularly through hunting and handling... view more... (2002-03-22)
LSUHSC research describes function of key protein in cancer spread
Research led by David Worthylake, PhD, Assistant Professor of Biochemistry and Molecular Biology at LSU Health Sciences Center New Orleans, may help lay the groundwork for the development of a compound to prevent the spread of cancer. view more (2009-05-22)
Artificial night lighting jeopardises the survival of sea life
Artificial night lighting can jeopardise the survival of sea turtles by obliterating environmental cues. Writing in the August issue of Biologist, Mike Salmon, of Florida Atlantic University, USA, explains how artificial coastal lighting disturbs female sea turtles' navigation to nest beaches and disorientates their hatchlings so that many fail to... view more...

A wandering eye
Eyes are among the earliest recognisable structures in an embryo; they start off as bulges on the sides of tube-shaped tissue that will eventually become the brain. view more (2006-08-25)
Scattered nature of Wisconsin's woodlands could complicate forests' response to climate change
If a warmer Wisconsin climate causes some northern tree species to disappear in the future, it's easy to imagine that southern species will just expand their range northward as soon as the conditions suit them. view more (2008-07-16)
Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
Populations of several European passerines that winter south of the Sahara have undergone a marked decline. The causes of negative population trends are largely unknown, but ecological conditions during winter in Africa may have carry-over effects during northward spring migration and reproduction. In the January issue of Ecology Letters, Saino,... view more... (2003-12-10)
