Worrying rise in deaths from alcoholic liver disease
Deaths from alcoholic liver disease have increased in the West Midlands in the past decade, reflecting a nationwide trend, according to researchers in this week's BMJ. The study was set in three boroughs in the West Midlands with a total population of 837,000. Death rates were obtained from the Office for National Statistics. Deaths from primary... view more...

5th annual Keys bonefish population census results announced
Results are in from last year's fifth annual Bonefish Population Census in the Florida Keys and the bonefish population has remained fairly steady from 2006, however, the number of volunteers participating in the annual event continues to grow. view more (2008-02-26)
Rodent size linked to human population and climate change
You probably hadn't noticed -- but the head shape and overall size of rodents has been changing over the past century. A University of Illinois at Chicago ecologist has tied these changes to human population density and climate change. view more (2009-07-31)
MU Researchers to Study the Status of Black Bears in Missouri
Researchers at the University of Missouri-Columbia are studying the status of black bears in Missouri. Black bears were abundant in the state during the 18th and 19th centuries, but have been considered almost extinct in Missouri since the late 19th century. view more (2007-06-14)
Scientists show that streams are critical to preservation of oceanic coastal zones
The plight of the world's oceans is dire, according to recent studies, through insults from human-derived activities depopulating and damaging reefs, altering coastlines, and creating pollutants, such as nitrogen runoff from terrestrial watersheds. view more (2008-03-13)

Balancing Use to Fill Today`s Gaps and Meet Tomorrow`s Needs: Water for People, Food and Environment Stockholm Water Symposium in August is last major global water forum before UN development summit in South Africa
To feed the planet`s 8 billion inhabitants in 2025, the world will need as much extra water simply for food production as is currently in use for - but not yet satisfying - our drinking, sanitation, industrial and irrigation needs. From where will this new water come? That question will be explored August 12 - 15 by attendees at the 2002... view more... (2002-08-06)
Unemployment always comes home
High unemployment rates have become one of the major economic concerns of most developed governments in the world. The automation of production processes, the relocation of Western companies in developing countries and the international crisis are giving rise to permanent high unemployment levels that seem immune to any economic policy measure... view more...

What Goes On Underneath Your Feet?
It is generally assumed that heat from Earth's core and mantle, due to the low thermal conductivity of the latter, is transferred to the outer part mainly by convection. This implies swirling movement of an immense amount of hot material, which is behind the dynamics of Earth's interior. Understanding the details of this is of great interest since... view more...

Viagra passes initial safety test, but more research is needed
A study in this week’s BMJ finds no evidence for a higher incidence of fatal heart attack or ischaemic heart disease among English men taking sildenafil (Viagra). Although reassuring, further evidence is needed to confirm these findings, report the authors. Users of sildenafil were identified from NHS prescriptions in England. Simple... view more...

Teenage Boys Exposed To Environmental Pollutants Less Likely To Produce Male Children (p143)
A research letter in this week's issue of THE LANCET provides further evidence that adolescent boys exposed to organic pollutants are less likely to father a male child in adulthood. Investigators from the National Cheng Kung University Medical College, Taiwan, and the London School of Hygiene and Tropical Medicine, UK, studied the sex of over... view more... (2002-07-10)
Changing the rings: a key finding for magnetics design
Researchers at the National Institute of Standards and Technology's Center for Nanoscale Science and Technology (CNST) have done the first theoretical determination of the dominant damping mechanism that settles down excited magnetic states-"ringing" in physics parlance-in some key metals. view more (2007-08-06)
Larger blood reserves needed for ageing population
Larger reserves of blood will be needed as the population ages, predict researchers in this week's BMJ. They recorded the use of nearly 10,000 units of red blood cells from all NHS hospital blood banks in the north of England. More than half (52%) of all units were given to medical patients, 41% to surgical patients, and 6% to obstetric and... view more... (2002-10-09)
Scientists present the largest-to-date genetic snapshot of Iceland 1,000 years ago
Scientists at deCODE genetics have completed the largest study of ancient DNA from a single population ever undertaken. Analyzing mitochondrial DNA, which is passed from mother to offspring, from 68 skeletal remains, the study provides a detailed look at how a contemporary population differs from that of its ancestors. view more (2009-01-16)
New Honorary Fellows at the Institute of Physics
Dr Clive Foxell, Professor Klaus von Klitzing, Lord Robert May and Professor Joe Vinen have been awarded Honorary Fellowships at the Institute of Physics in recognition of their outstanding contributions to physics. Dr Clive Foxell has given exceptional service to the Institute of Physics and the physics community. He was President of the... view more... (2002-09-30)
There's a speed limit to the pace of evolution, Penn biologists say
Researchers at the University of Pennsylvania have developed a theoretical model that informs the understanding of evolution and determines how quickly an organism will evolve using a catalogue of "evolutionary speed limits." view more (2009-11-03)
£100 Million For World Leading New Science Project
The UK's world-beating neutron centre at the Rutherford Appleton Laboratory, near Didcot, is to get one of the largest ever awards of Government funding for a single science project, Science Minister Lord Sainsbury announced today. The DTI is giving over £100 million to fund a brand new wing at the ISIS neutron laboratory. This expansion... view more... (2003-04-08)
Schizophrenia risk highest in small ethnic groups
The rate of schizophrenia among people from non-white ethnic groups rises as the proportion of these groups fall in the local population, finds a study in this week's BMJ. view more (2001-12-05)
Novel laboratory model reveals clues to how blood starts clotting
Researchers at the University of Chicago have crafted a simple model for predicting when and where hemostasis - the technical term for blood clotting - will occur. view more (2006-10-27)
Born to lose: How birth weight affects adult health and success
Birth weight has significant and lasting effects, a new study finds. Weighing less than 5.5 pounds at birth increases the probability of dropping out of high school by one-third, reduces yearly earnings by about 15 percent and burdens people in their 30s and 40s with the health of someone who is 12 years older. view more (2007-06-06)
