New research on the fruit-fly brain points to a possible mechanism by which temperature influences the body clock, as per researchers from Queen Mary, University of London. Eventhough much is known about how light affects the body clock - also known at the circadian clock - it is not well understood which cells or organs sense daily temperature changes or how temperature signals reach the part of the brain that contains the circadian clock……..

When Charles Darwin published The Origin of Species 150 years ago, he deliberately avoided the subject of the origin of life. This, coupled with the mention of the ‘Creator’ in the last paragraph of the book, led us to believe he was not willing to commit on the matter. An international team, led by Juli Peret of the Cavanilles Institute in Valencia, now refutes that idea and shows that the British naturalist did explain in other documents how our first ancestors could have come into being……..

An Australian method for assessing the environmental impact of marine fisheries has caught the eye of fishery management agencies worldwide. Aspects of the ‘ecological risk evaluation’ (ERA) method have been adopted in the US, Canada, Ecuador, and the Western and Central Pacific, and by the international eco-labelling organisation the Marine Stewardship Council……..

Vertebrates have in common a skeleton made of segments, the vertebrae. During development of the embryo, each segment is added in a time dependent manner, from the head-end to the tail-end: the first segments to be added become the vertebrae of the neck, later segments become the vertebrae with ribs and the last ones the vertebra located in the tail (in the case of a mouse, for example). In this process, it is crucial that, on the one hand, each segment, as it matures, becomes the correct type of vertebra and, on the other, that the number of vertebrae in the skeleton, and therefore the size of the spine, are minutely controlled……..

The remarkable eyes of a marine crustacean could inspire the next generation of DVD and CD players, as per a newly released study from the University of Bristol published recently in Nature Photonics The mantis shrimps in the study are found on the Great Barrier Reef in Australia and have the most complex vision systems known to science. They can see in twelve colours (humans see in only three) and can distinguish between different forms of polarized light……..

ATLANTA Did you know that millions of tons of fruits and vegetables in the United States end up in the trash can before being eaten, as per the U.S. Department of Agriculture? A Georgia State University professor has developed an innovative new way to keep produce and flowers fresh for longer periods of time……..

An international team of scientists from the United States, Korea, and France has sequenced and analyzed the genomes of two important laboratory strains of E. coli bacteria, one used to study evolution and the other to produce proteins for basic research or practical applications. The findings will help guide future research and will also open a window to a deeper understanding of classical research that is the foundation of our understanding of basic molecular biology and genetics……..

Logged rainforests can support as much plant, animal and insect life as virgin forest within 15 years if properly managed, research at the University of Leeds has found. Because trees in tropical climates soak up large amounts of carbon dioxide, restoring logged forest through planting new trees could also be used in carbon trading, as per Dr David Edwards, from University’s Faculty of Biological Sciences……..

A 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research advances, scientists said. Charles Darwin’s seminal Origin of Species first laid out the case for evolution exactly 150 years ago. Now, MSU professor Richard Lenski and his colleagues document the process in their analysis of 40,000 generations of bacteria, published this week in the international science journal Nature…….

Pairing a new approach to prepare ancient DNA with a new scientific technique developed specifically to genotype a cow, an MU animal scientist, along with a team of international researchers, created a very accurate and widespread “family tree” for cows and other ruminants, going back as far as 29 million years. This genetic information could allow researchers to understand the evolution of cattle, ruminants and other animals. This same technique also could be used to verify ancient relatives to humans, help farmers develop healthier and more efficient cattle, and assist researchers who are studying human diseases, as per the research, which is being published in this week’s edition of the Proceedings of the National Academy of Sciences (PNAS)……..
