The future of tropical forests
Deforestation and habitat loss are expected to lead to an extinction crisis among tropical forest species. Humans in rural settings contribute most to deforestation of extant tropical forests.   view more (2006-04-07)

Improving quality of life for indigenous peoples
Further efforts are needed to improve the health and wellbeing of indigenous peoples in developed countries all over the world, according to a report published today in the online open access journal, BMC International Health and Human Rights. The study points to a worrying lack of progress for the... view more (2007-12-20)

Viral marker of human migration suspect
A benign virus previously used as a marker in tracing human migration may be unreliable.   view more (2006-10-25)

Improved estimates of population extinction risk (Harding and McNamara)
An important application of theoretical ecology is in estimation of species extinction risk. Extinction models guide the selection of management regimes for endangered species. Two vital parameters in these models are the mean population growth rate and its variance. However, empirical data on... view more (2003-12-10)

Fly population set to double with global warming
A leading biological scientist from the University of Southampton is warning of massive increases in the UK's fly population if temperatures continue to rise.   view more (2004-09-27)

Mean Population Size Increases with Diversity
A long-standing debate in ecology has been the effect of diversity on the temporal stability of biological systems. Ecological theory predicts that the stability of populations should decline as community diversity increases, in part, because population size is assumed to decline with community... view more (2003-01-28)

Risk threshold of daily alcohol intake and drinking duration in liver injury?
Alcoholic threshold effect rather than a dose-response effect on mortality from alcohol-related liver injury. Alcohol intake, rather than the type of alcoholic beverage, was more significant to liver injury.   view more (2008-05-21)

Carnivore extinction risk determined more by biology than human population density, says study
Carnivores around the world are more at risk of extinction due to their own intrinsic biological attributes than from an increasing human population with whom they share their space, say scientists in a study published this week. Researchers looking at all 280 carnivore species around the world... view more (2004-07-15)

HUMAN RIGHTS - ANGOLA'S SUFFERING BEHIND A PRETENCE OF NORMALITY (p 2093)
The Angolan government must commit to rebuilding the country's health-care infrastructure for its population that has been war-torn for a quarter of a century and facing increasing medical needs, concludes a human rights article in this week's issue of THE LANCET. Nathan Ford and colleagues from... view more (2000-12-13)

Twins have lower risk of suicide than general population
Twins have a lower risk of suicide compared with the general population, concludes a study in this week’s BMJ.   view more (2003-08-12)

Researchers make progress in studying genetic traits of India-born populations
Despite the fact that the people of India constitute more than one-sixth of the world's entire population, they have been underrepresented in studies related to genetic diseases.   view more (2006-12-26)

DNA research flies high with Seychelles kestrel
A new research project at the University of Kent is looking for genetic evidence of a historical population bottleneck in the Seychelles kestrel by analysing DNA extracted from museum specimens estimated to be 100-150 years old. Dr Jim Groombridge, Lecturer in Biodiversity Conservation at the... view more (2004-06-01)

U of MN researchers identify new cord blood stem cell
Researchers at the University of Minnesota Medical School have discovered a new population of cells in human umbilical cord blood that have properties of primitive stem cells.   view more (2006-02-14)

Bar flies: fruit flies help unravel the genetics of alcohol sensitivity
Research published in the online open access journal Genome Biology this week has identified a number of genes that are associated with sensitivity to alcohol in fruit flies (Drosophila melanogaster).   view more (2007-10-31)

Yale biologists 'trick' viruses into extinction
While human changes to the environment cause conservation biologists to worry about species extinction, Yale biologists are reversing the logic by trying to trap viruses in habitats that force their extinction, according to a report in Ecology Letters.   view more (2007-02-13)

DNA analysis reveals rapid population shift among Pleistocene cave bears
Studying DNA obtained from teeth of ancient cave bears, researchers have been able to identify a shift in a particular population of the bears inhabiting a European valley in the late Pleistocene era.   view more (2007-02-20)

Detecting transmissibility of avian influenza virus in human households
Recent outbreaks of emerging diseases such as SARS and H5N1 avian influenza have underlined the fact that animal pathogens may acquire the ability to spread efficiently in humans - but as yet have not.   view more (2007-07-26)

Fighting for their attention
Mating strategies are straightforward in bottlenose dolphins, or are they? Much of the work carried on male-female relationships in that species to date show that males tend to coerce females who are left with little choice about with whom to mate.   view more (2007-04-04)

Spread of endogenous retrovirus K is similar in the DNA of humans and rhesus monkeys
According to paleontologic and molecular studies, the chimpanzee (Pan troglodytes) is the closer relative to the humans (Homo sapiens) and that both lineages had a common ancestor at 5 to 7 million years ago.   view more (2007-10-10)

Titanic survivors lived no longer than general population
In the closing song of the 1997 film Titanic, the heroine tells us that her heart "must go on and on" but a study in this week's Christmas issue of the BMJ shows that Titanic survivors lived no longer than the general population.   view more (2003-12-17)

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)

The song doesn't remain the same in fragmented bird populations
The song of passerine birds is a conspicuous and exaggerated display shaped by sexual selection in the context of male-male competition or mate attraction. At the level of the individual, song is considered an indicator of male 'quality'.   view more (2008-03-19)

Bushmeat poses threat of simian retrovirus transmission to humans (pp 911, 932)
Epidemiological research from central Africa in this week's issue of THE LANCET highlights how a new form of retrovirus - simian foamy virus (SFV) - can be transferred from primates to humans as a result of hunting for bush meat. Although the effect of simian foamy viruses on human health is not... view more (2004-03-17)

UK Study Suggests Possible Link Between Colorectal Cancer And Human Growth Hormone Therapy (p 273)
Authors of an observational study in this week's issue of THE LANCET highlight a possible link between human growth hormone therapy and an increased risk of colorectal cancer. The investigators comment that further evidence is required before firm conclusions can be made, and stress that there is... view more (2002-07-24)

New population of Iberian lynx raises hope, says World Wildlife Fund
Spanish authorities have announced they have discovered a previously unknown population of Iberian lynx, triggering hope for one of the world's most endangered cat species, said World Wildlife Fund today.   view more (2007-10-24)
