Is there anybody out there?
Is there anybody out there? Probably not, according to a scientist from the University of East Anglia. A mathematical model produced by Prof Andrew Watson suggests that the odds of finding new life on other Earth-like planets are low, given the time it has taken for beings such as humans to evolve and the remaining life span of Earth. view more (2008-04-17)
Geologists point to outer space as source of the Earth's mineral riches
According to a new study by geologists at the University of Toronto and the University of Maryland, the wealth of some minerals that lie in the rock beneath the Earth's surface may be extraterrestrial in origin. view more (2009-10-19)
Study points to molecular origin of neurodegenerative disorders, including Huntington's disease
New research from the University of North Carolina at Chapel Hill School of Medicine points to the possible molecular origin of at least nine human diseases of nervous system degeneration. view more (2005-09-26)
Sell-by date "arbitrary" on some food packaging
New research on untreated green olives has found that products with a stated shelf-life of 2-3 years can be 'unacceptable' long before their sell-by date. The study, published in the Journal of the Science of Food and Agriculture, looked at the growing trend towards using polyethylene pouches which are vacuum-packed, filled with brine or packed in... view more...

Should we help to create disabled babies?
Should genetic tests be offered to couples seeking to have a child to allow them to select for disability? Many would see deliberately creating disabled babies as the most perverse manifestation of creating designer babies but, in this week's BMJ, Julian Savulescu argues that there may be good reasons for acceding to such requests. We offer... view more... (2002-10-02)
Asian families in obesity probe
Researchers at the University of Leicester have launched one of the biggest studies into childhood obesity in the UK, funded by the British Heart Foundation. The key aim of the £100,000 two-year project is to determine the prevalence of health diet and physical activity behaviour in children of South Asian origin and to evaluate an action... view more...

Individuals whose mothers drink three or more glasses of alcohol at any one occasion in early pregnancy have an increased risk of developing alcohol disorders by 21 years of age. view more (2006-09-05)
How left-handed amino acids got ahead: a demonstration of the evolution of biological homochirality in the lab
A chemical reaction that demonstrates how key molecules in the biological world might have come to be predominately left or right handed has been reported by scientists at Imperial College London. Ever since discovering that the building blocks of the biological world, such as amino acids and sugars, are distinctively left or right handed -... view more... (2004-06-21)
Life Lessons: Where Psychology Stands on Living Well
Unfortunately for us, there is no formula for fulfillment or guide to life satisfaction; however, humans have turned to philosophy, religion and science time and again for answers to our existential questions. view more (2009-07-23)
Stress Is Founded To Be Associated With Hyperprolactinemia
A group of Italian investigators headed by Nicoletta Sonino (University of Padova) has performed the first controlled investigation on the relationship between stressful life events and an endocrine disease characterized by increased prolactin levels (hyperprolactinemia). Little is known about the relationship between recent life events and onset... view more... (2004-07-20)
Cassini 'CAT Scan' maps clumps in Saturn's rings, says UCF researcher, team
Saturn's largest and most densely packed ring is composed of dense clumps of particles separated by nearly empty gaps, according to new findings from NASA's Cassini spacecraft. view more (2007-05-23)
Scripps scientists develop first examples of RNA that replicates itself indefinitely
Findings could inform biochemical questions about how life began. Now, a pair of Scripps Research Institute scientists has taken a significant step toward answering that question. The scientists have synthesized for the first time RNA enzymes that can replicate themselves without the help of any proteins or other cellular components, and the... view more... (2009-01-12)
Embryonic heart exhibits impressive regenerative capacity
A new study demonstrates that the embryonic mouse heart has an astounding capacity to regenerate, a phenomenon previously observed only in non-mammalian species. view more (2008-10-14)
Essential Hope for Multiple Sclerosis
New research by psychologists reveals the positive effects of aromatherapy on the quality of life for Multiple Sclerosis (MS) sufferers.

Dingo's Mother A Chinese Domesticated Dog
The Australian dingo descends from domesticated dogs that people from Southeast Asia brought with them to Australia some 5,000 years ago. Genetic studies indicate that it is probably a matter of a single occasion and a very small number of dogs. The story begins when a few domestic dogs originally originating from East Asia, jump ashore from a... view more... (2004-08-06)
Penn Veterinary Researchers Identify a Critical Growth Factor That Stimulates Sperm Stem Cells to Thrive
Researchers at the University of Pennsylvania School of Veterinary Medicine and Pennsylvania State University have identified for the first time a specific "niche factor" in the mouse testes called colony stimulating factor 1, Csf1, that has a direct effect on sperm stem cell self-renewal. view more (2009-03-09)
Clues To Supernova Origin Found In Dusty Stellar Wind
Scientists from Imperial College London have detected a dusty wind emitted by a star that, at the end of its life, turned into a white dwarf and then exploded as a supernova. This is the first time that a wind from this type of supernova precursor has been observed and it is also the first time that associated dust has been detected. The... view more... (2005-03-30)
The Immune System In Autism
Autism suffers present a widespread range of antibodies against brain tissue and one protein in particular seems to be the major target of these antibodies claim a group of scientists in the July issue of the Journal of Neuroimmunology. The researchers also show that these antibodies are not genetically determined, as parents of affected... view more... (2004-07-23)
