Scientists discover bizarre new fish off Brazil's Bahia coastSeptember 22nd, 2009 WASHINGTON - Scientists have discovered a previously unknown species off Brazil's Bahia coast, which is more than six feet long, has small teeth, and has no scales covering its gelatinous body. According to a report in National Geographic News, the fish that has a long tail, was found floating in the sea by researchers from the TAMAR Project, a sea turtle conservation project.
Drug-free cannabis plant comes closer to realitySeptember 16th, 2009 WASHINGTON - Scientists have come closer to engineering drug-free cannabis plant after identifying genes that produce psychoactive substance in marijuana. University of Minnesota researchers have identified genes producing tetrahydrocannabinol (THC), the psychoactive substance in marijuana, which could lead to new and better drugs for pain, nausea and other conditions.
Scientists isolate genes that imbue us with uniquely human traitsSeptember 2nd, 2009 WASHINGTON - Humans and chimpanzees are genetically very similar yet clearly distinct in many ways. Scientists have isolated genes that evolved in humans after branching off from other primates, making us uniquely human.
What makes us uniquely humanSeptember 2nd, 2009 WASHINGTON - In a remarkable piece of detective work, scientists working at Trinity College Dublin have discovered three genes that are unique to humans. In the study published online in Genome Research, boffins have made a crucial discovery of genes that have evolved in humans after branching off from other primates.
'Robofish' take to the water to monitor environmental contaminantsAugust 31st, 2009 WASHINGTON - MIT (Massachusetts Institute of Technology) scientists in the US have developed a school of small robotic fish, which are equipped with sensors to monitor oil spills or other environmental contaminants. According to a report in Discovery News, the robofish, made with only handful of parts and a blend of polymers, can wiggle their way through water like trout and tuna.
New, improved zebrafish cloning method may further human health researchAugust 31st, 2009 LONDON - In what may eventually prove very useful in human health research, scientists at Michigan State University have come up with a more efficient method to clone zebra fish. What makes this work an important achievement is the fact that zebra fish, which have served as an excellent model for understanding normal development and birth defects for more than 20 years, are quickly becoming the animal of choice for many researchers.
Cleaner fish wear 'uniforms' to signal their professions to clientsAugust 21st, 2009 WASHINGTON - A new study has determined that like police and nurses, cleaner fish on coral reefs wear 'uniforms', which are basically colors and body patterns, to signal their "professions" - a tactic that also helps the fish avoid being eaten by their clients. Several species of small reef fish are known to invite larger fish to stop by "cleaning stations," where the cleaners groom their customers and pick them free of parasites.
Fish fear divers and snorkelers who try to count them for censusJuly 21st, 2009 WASHINGTON - A new research by scientists from the University of Victoria has shown that fish avoid the divers and snorkelers who try to count them, and that is why using snorkelers and SCUBA divers may misrepresent the number of fish. Not all types of fish are equally frightened by the divers, and Faculty of 1000 member Helen Yap, who recommended the study, explains that therefore "such methods may not provide an accurate picture of the actual diversity and abundance of fish communities."
Counting coral reef fish informs researchers about local ecological changes.
Male sex chromosome on way to extinctionJuly 17th, 2009 WASHINGTON - The sex chromosome that only males carry is deteriorating and could disappear within a few million years. A pair of Penn State University (PSU) scientists discovered that the male Y chromosome evolved at a much more rapid pace than X chromosome, which both males and females carry.
Male sex chromosome facing extinction due to rapid evolutionJuly 17th, 2009 WASHINGTON - A new research has revealed that the sex chromosome that only males carry is deteriorating and could disappear within a few million years. Scientists at Penn State University (PSU) found that the male Y chromosome evolved at a much more rapid pace than X chromosome, which both males and females carry.
Rock-solid self-confidence is in the genesJuly 2nd, 2009 LONDON - If you always attributed a rock-solid self-confidence to upbringing and other environmental factors then better think again, for an unshakeable self belief is in the genes, according to a new study. The psychiatrists behind the study say that the ability to perform under pressure is more than a state of mind, and that some people are just born with it.
Farmed fish may transmit mad cow diseaseJune 17th, 2009 WASHINGTON - Farmed fish, if fed by-products rendered from cows, could transmit Creutzfeldt Jakob disease-commonly known as mad cow disease. Questioning the safety of eating farmed fish, Dr.
The biological basis for the 8-hour work-shiftApril 24th, 2009 WASHINGTON - Your usual nine to five office shift has a biological reason behind it, and now scientists have found that some genes in the body are switched on once every 12 or 8 hours, which in turn keeps us actively involved in the work, according to a new study. The findings by researchers at the University of Pennsylvania School of Medicine and the Salk Institute for Biological Studies indicated that shorter cycles of the circadian rhythm are also biologically encoded.
Genes that protect against aging identifiedApril 21st, 2009 WASHINGTON - University of Liverpool researchers have developed a novel method to help scientists identify genes that can help protect the body during the ageing process. The team developed a method of analysing genes in multiple ageing tissue types in both animals and humans.
Genes linked to spinal disc degeneration identifiedMarch 14th, 2009 WASHINGTON - Researchers from University of Alberta have identified certain genes responsible for spinal disc degeneration. Michele Crites-Battie and Tapio Videman, in the Faculty of Rehabilitation Medicine, have discovered eight genes linked to lumbar disc degeneration.
