Size of brain structure could signal vulnerability to anxiety disorders
The size of a particular structure in the brain may be associated with the ability to recover emotionally from traumatic events. A new study by researchers from Massachusetts General Hospital (MGH) finds that an area called the ventromedial prefrontal cortex is thicker in volunteers who appear... view more (2005-07-12)

Global task force to save the albatross wins backing of The Prince of Wales
The Prince of Wales and record-breaking sailor, Ellen MacArthur, are together to trumpet global efforts to save one of the world's most endangered yet iconic birds.   view more (2005-04-26)

New global bird map suggests 'hotspots' not a simple key to conservation
The first full map of where the world's birds live reveals their diversity 'hotspots' and will help to focus conservation efforts, according to research published in Nature today (18 August).   view more (2005-08-18)

All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon... view more (2003-05-22)

Global warming increases species extinctions worldwide
Global warming has already caused extinctions in the most sensitive habitats and will continue to cause more species to go extinct over the next 50 to 100 years, confirms the most comprehensive study since 2003 on the effects of climate change on wild species worldwide by a University of Texas at... view more (2006-11-15)

New modeling study forecasts disappearance of existing climate zones
A new climate modeling study forecasts the complete disappearance of several existing climates in tropical highlands and regions near the poles, while large swaths of the tropics and subtropics may develop new climates unlike any seen today.   view more (2007-03-28)

Why does species diversity vary so much?
The diversity of life varies predictably with climate and is greatest where it is warm and wet (the humid tropics). But the question "why" has puzzled biologists for over a century. In the December issue of Ecology Letters, Currie and colleagues examine three hypotheses about the origin... view more (2005-01-11)

New 150 Million-Year-Old Crab Species Discovered
Researchers from Kent State University and the University of Bucharest, Romania, have discovered a new primitive crab species Cycloprosopon dobrogea in eastern Romania. Previously unexamined, these ancient crabs from the Prosopidae family existed more than 150 million years ago during the Jurassic... view more (2007-10-18)

Brown tree snake could mean Guam will lose more than its birds
In the last 60 years, brown tree snakes have become the embodiment of the bad things that can happen when invasive species are introduced in places where they have few predators. Unchecked for many years, the snakes caused the extinction of nearly every native bird species on the Pacific island of... view more (2008-08-11)

The spread of our species
In a major new development in human evolutionary studies, researchers from the University of Cambridge argue that the dispersal of modern humans from Africa to South Asia may have occurred as recently as 70,000 years ago.   view more (2005-11-07)

Global warming capable of sparking mass species extinctions
The Earth could see massive waves of species extinctions around the world if global warming continues unabated, according to a new study published in the scientific journal Conservation Biology.   view more (2006-04-12)

Study shows big game hunters, not climate change, killed off sloths
Prehistoric big game hunters and not the last ice age are the likely culprits in the extinction of giant ground sloths and other North American great mammals such as mammoths, mastodons and saber-toothed tigers, says a University of Florida researcher.   view more (2005-08-04)

FSU scientist warns North Atlantic right whale facing extinction
The North Atlantic right whale's future looks grim if the current mortality rates continue, according to Florida State University assistant professor of oceanography Douglas Nowacek and a group of fellow scientists from across the nation.   view more (2005-07-25)

New study explores patterns in species diversity and genetic diversity
As scientists, conservationists, and policy-makers wrestle with how to balance development with maintaining biodiversity, it's important to understand what controls patterns of biodiversity and how the biodiversity of a system will respond to different environmental scenarios.   view more (2005-07-27)

Insect attack may have finished off dinosaurs
Asteroid impacts or massive volcanic flows might have occurred around the time dinosaurs became extinct, but a new book argues that the mightiest creatures the world has ever known may have been brought down by a tiny, much less dramatic force - biting, disease-carrying insects.   view more (2008-01-03)

Extinction threat growing for mankind's closest relatives
Mankind's closest relatives - the world's monkeys, apes and other primates - are disappearing from the face of the Earth, with some literally being eaten into extinction.   view more (2008-08-05)

Refining the date of the K/T boundary and the dinosaur extinction
Scientists at the University of California, Berkeley, and the Berkeley Geochronology Center have pinpointed the date of the dinosaurs' extinction more precisely than ever thanks to refinements to a common technique for dating rocks and fossils.   view more (2008-04-25)

Smithsonian perspective: Biodiversity in a warmer world
Will climate change exceed life's ability to respond? Biodiversity in a Warmer World, published in the Oct. 10, 2008 issue of the journal, Science, illustrates that cross-disciplinary research fostered by the Smithsonian Tropical Research Institute in Panama clearly informs this urgent debate.   view more (2008-10-10)

Is the Sagittarius dwarf galaxy a debris of the Large Magellanic Cloud?
The Sagittarius dwarf galaxy is our nearest neighbor. Yet it has been discovered only recently, in 1994, being hidden by the stars and dust in our own Galaxy, the Milky Way. It is however possible today to better know this companion galaxy, thanks to variable stars, the RR Lyrae, in which Sgr-dw is... view more (2002-02-25)

Alien predators are more dangerous than native predators
Introduced predators such as foxes and cats are twice as deadly as native predators to Australia's unique native animals, a new study has found.   view more (2007-03-14)

New study reveals large scale conservation essential
Scientists were surprised with findings of a recent study that reveals many animal species believed to persist in small contained areas actually need broad, landscape level conservation to survive.   view more (2008-06-10)

Bison reintroduction to Central Russia
Russian scientists are investigating the opportunity to bring wisents (Bison bonasus) back to the forests of Central Russia. Their effort has been funded by the Russian Foundation for Basic Research and the Federal Target Scientific and Technical Program called "Conservation of Rare... view more (2004-05-17)

Species Have Come and Gone at Different Rates than Previously Believed
Diversity among the ancestors of such marine creatures as clams, sand dollars and lobsters showed only a modest rise beginning 144 million years ago with no clear trend afterwards, according to an international team of researchers. This contradicts previous work showing dramatic increases beginning... view more (2008-07-07)

Are men in danger of extinction?
Despite having had most of the social determinants of health in their favour, men have higher mortality rates for all 15 leading causes of death and have a life expectancy about seven years shorter than women's. An editorial in this week's BMJ asks are men in danger of extinction? Men's reluctance... view more (2001-10-31)

New space telescope aims to seek out and record explosive gamma ray bursts.
A state of the art space telescope built by scientists at UCL will make its way to the Goddard Space Flight Centre in Maryland, USA on a mission to unravel the mysteries of the universes gamma rays. The telescope - called UVOT - will be one of three telescopes on a special NASA orbiting space... view more (2002-05-31)
