Globally every year, obese people waste billions on food products that 'imply' that they aid weight loss, but are totally ineffective, says a nutritional expert on British Medical Journal (www.bmj.com) today. 

Professor Lean from the University of Glasgow, is hopeful that a new European Union (EU) Directive on Unfair Commercial Practices, adopted this year in UK, will finally protect vulnerable consumers who are tricked into to buying useless food products or supplements in attempts to combat their disease. 

Unlike medicines, food products that are marketed for health reasons are not subject to the same stringent research trials and control, and consumers are often misled. 

Take out carbon credit politics and misplaced technical concerns, says the World Agroforestry Center , and existing technology that could effectively monitor carbon storage in developing country landscapes could save more carbon than closing 1,400 coal-burning power plants.

No one needs to tell Disney, who brought the likes of Herbie the Love Bug and Lightning McQueen to the big screen, that cars have personalities.   A study co-authored by a Florida State University researcher says it has confirmed through a complex statistical analysis that many people see human facial features in the front end of automobiles and ascribe various personality traits to cars -- a modern experience driven by our prehistoric psyches.

Researchers, product designers and, of course, filmmakers have long toyed with the idea that cars have faces, but this study is the first to investigate the phenomenon systematically. The study will be published in the December issue of the journal Human Nature.

Media coverage of clinical trials does not contain the elements readers require to make informed decisions. A comparison of the coverage received by pharmaceutical and herbal remedy trials, reported in BMC Medicine, has revealed that it is rarely possible for the lay public to assess the credibility of the described research.

Bone growth is controlled in the gut through serotonin, the same naturally present chemical used by the brain to influence mood, appetite and sleep, according to a new discovery from researchers at Columbia University Medical Center. Until now, the skeleton was thought to control bone growth, and serotonin was primarily known as a neurotransmitter acting in the brain. This new insight could transform how osteoporosis is treated in the future by giving doctors a way to increase bone mass, not just slow its loss. Findings are reported in the Nov. 26, 2008 issue of Cell.

Enormous cave bears, Ursus spelaeus, that once inhabited a large swathe of Europe, from Spain to the Urals, died out 27,800 years ago, around 13 millennia earlier than was previously believed, scientists have reported.  

Despite over 200 years of scientific study – beginning in 1794 when a young anatomist, J. Rosenmüller, first described bones from the Zoolithenhöhle in Bavaria as belonging to a new extinct species, which he called cave bear – the timing and cause of its extinction remain controversial.

I’ve recently touched on the delicate topic of human nature. Now it's the turn of the even more inflammatory subject of race. The occasion is provided by a short commentary in Science (1), reporting on a meeting of the National Human Genome Research Institute (NHGRI). The reason that meeting was contentious is because of increasingly common research on differences in the genetic susceptibility to diseases among human populations, where “population” is often a thinly veiled synonym for race.

Every type of disease has a specific treatment program. We have drugs to treat symptoms of countless illnesses and maladies, but viral infections continue to elude treatment. While we have vaccines to prevent initial infection of some viruses and other medications to treat problematic symptoms, there is little one can do to prevent a virus from replicating and causing disease. Viral infections can be lethal and without treatment options, we are left with our own natural defenses to fight off viral invaders. This is about to change.

Scientists have detected an organic sugar molecule that is directly linked to the origin of life, in a region of our galaxy where habitable planets could exist.  The international team of researchers, including a researcher at University College London (UCL), used the IRAM radio telescope in France to detect the molecule in a massive star forming region of space, some 26000 light years from Earth.
 

The Secretariat of the Joint United Nations Programme on HIV/AIDS (UNAIDS) has lost valuable ground by ignoring for years the contribution of long-term concurrent relationships to Africa's AIDS epidemic, claims says Helen Epstein, an independent consultant on public health in developing countries, ahead of World AIDS Day on British Medical Journal (www.bmj.com) today.
