Human and chimpanzee genes differ by a mere 1.2 per cent, which is insufficient to explain the differences between the two species. About 30 years ago, Mary-Claire King and Alan Wilson had proposed it is not genes but their expression that differentiates us from primates. Now, Matthew Rockman of Duke …
scientists have raised concern over India lacking a programme to regularly monitor harmful algal blooms (habs), which may lead to massive fish kills and even threaten public health. Though non-toxic blooms have been commonly reported from Indian waters, the cases of hab s have been on the rise since 1981. …
With President Abdul Kalam flagging off a centre for stem cells research at the Christian Medical College yesterday, the renowned college and hospital in Vellore, 200 km from Chennai, will join intensive global research in stem cell applications. Located in the CMC campus, the Centre for Stem Cell Research, to …
The world's oceans contain many more types of microorganisms than had been thought, scientists report. "Microbiologists have formally described 5,000 microbial species. This study shows we have barely scratched the surface," said Mitchell Sogin of the Marine Biological Laboratory at Woods Hole, Massachusetts.
Environmental factors can lead to genetic mutation by generating new gene alleles (either of a pair of genes). The new allele may improve its suitability (of propagation in subsequent generations) within the organism and increases its frequency, or decrease its suitability and finally disappear. Such interactions of genes with environment …
thevisual system of bees is more sophisticated than believed, claims a study conducted at the University College London (ucl) that showed the insects solved complicated colour puzzles. The study sheds light on how brain resolves one of the most difficult challenges of vision: recognising different surfaces under different colours of …
Everything seemed so bright for pioneering South Korean stem cell scientist Hwang Woo-suk just a few weeks ago after two major breakthroughs this year. Now the man who made world headlines by cloning a dog faces a swirl of allegations over the ethics of his team's work. The Seoul National …

a 3.8 metre-long female great white shark has completed the first documented round-trip ocean crossing by a shark. It travelled from South Africa across the Indian Ocean to Australia
Hungry or full, fat or thin: it is mostly a matter of hormones, dozens of them, carrying messages between the digestive tract, the fat cells and the brain. Eat. Don't eat. Burn calories. Store fat. Researchers at Stanford University are reporting that they have found a previously unknown member of …
As a precursor to the Biotechnology Policy, the Government on Thursday announced its intention to work closely with the private sector for stem cell research. It will fund private sector to scale-up development of stem cells to be used by medical colleges for therapeutic treatment. The immediate focus is on …
The inspiration behind Mark Twain's fable, "The Celebrated Jumping Frog of Calaveras County', may be facing a serious threat to its existence. A federal judge in San Francisco has asked the US Environmental Protection Agency (EPA) to investigate if 66 pesticides commonly used in agriculture are endangering the California red-legged …
When a sperm joins an egg fertilization takes place. The product of this union is the embryo. Stem cells are cells found in the embryo, which are capable of reproducing any cell type. (pluripotency). In the human, there are about 200 such cell types. Stem cells are also found in …
The New York Stock Exchange told a US Senate committee that it is still reviewing the application of an animal-testing company whose listing was postponed last month, minutes before it was slated to start trading. Richard P. Bernard, general counsel for the NYSE, apologized to Life Sciences Research Inc. for …
A major scientific step in the field of genetics is set to speed up the search for the causes of common illnesses ranging from heart disease and cancer to Alzheimer's and asthma, researchers said. They have completed a map that charts patterns of human genetic variation in the world population, …
US Federal regulators have approved what would be the first transplant of fetal stem cells into human brains, a procedure that if successful could open the door to treating a host of neural disorders. The transplant recipients will be children who suffer from a rare, fatal genetic disorder. The Food …
The government launched on wednesday a stem cell hub headed by scientist Hwang Woo-suk to preserve the nation's pioneering role in stem cell technology for treatment of diseases. The World Stem Cell Hub, set up at Seoul National University Hospital, will distribute stem cells to other laboratories across the globe …
With stem cell therapy providing a cure for various disordrs, at least 150 couples in Chennai have opted over the last six months to bank their childrens' cord stem cells in the city's only private umbilical bank, Life cell. They see it as a biological insurance for their offisprings' future, …
Scientists have devised a new technique to derive embryonic stem cells in mice, which avoids the destruction of the embryo, a development that could shift the grounds of the longstanding political debate about human stem cell research. Until now the only way of deriving human embryonic stem cells has been …
In experiments with mice, two separate groups of scientists have found ways to derive embryonic stem cells without destroying viable embryos. If these techniques can be replicated in humans, they may help ease ethical and political concerns over stem-cell use. "The hope is that these will be a platform for …
