Scientists discover protein that extends life

Scientists at the Massachusetts Institute of Technology (MIT) have discovered a protein that extends life by as much as 50 per cent. The protein is released in the body during times of famine, according to research published today in the journal Nature.

Group defence

ever wondered why people have different blood groups? A study shows that blood groups evolved to confer upon humanity defence against viral and bacterial diseases. Humans either have blood group a, b, ab or o. Each type occurs at different frequencies across the world. Robert Seymour and his colleagues from …

Group sues over embryo diagnosis ban

Maternity clinic doctors and their clients sued the Japan Society of Obstetrics and Gynecology for curbing the controversial preimplantation diagnosis of embryos to prevent transmission of genetic diseases. The plaintiffs said the restrictions run counter to the Constitution's guarantee of the right to bear children and pursue happiness. They want …

Coming of age: baby born from 21-year-old frozen sperm

The birth of a baby boy, created using sperm frozen for a world-record 21 years, offers new hope to thousands of young people who may lose their fertility after cancer treatment, doctors said. The child, born in 2002, could have been conceived in the year that Pol Pot's regime fell …

U.S. slipping behind in stem cell research

Although the first human embryonic stem cell line was created in the United States, the majority of new embryonic cell lines

A new centre for genomic research

The frist public-private partnership genomic application research facility has been set up at Okhla in South Delhi. The research and development facility can be used as a shared resource for all the research centres in the country.

1,800 new species found

Genome experts who took on a patch of ocean for a mass gene-sequencing project said they had discovered at least 1,800 new species of microbes and changed some of their fundamental ideas about ocean biology.

Brain changes in gay sheep

Researchers who found homosexual rams in a herd of sheep said they had found changes in the brains of the 'gay' animals.

Antifreeze protein protects flounder in icy seas

Scientists in Canada have discovered a new antifreeze protein that enables the winter flounder to survive in freezing polar oceans. Thirty years ago researchers identified an antifreeze protein (AFP) known as type 1 in flounder which protected the fish down to a temperature of -1.5 degrees Centigrade. But it didn't …

UK may give nod to cloned embryo

A plan to create the first cloned human embryo in Britain by the end of the year is expected to receive the go-ahead within weeks following a licence application from a team of medical researchers at Newcastle University. Scientists insisted on Friday that the aim of the research is to …

Birth of a new generation: Five cell donor babies in US

Building on the high-tech science that lets couples choose their babies' sex or screen for genetic disorders, researchers are reporting the birth of five children from embryos created in a lab so they could serve as cell donors to seriously ill siblings. Scientists at Chicago's Reproductive Genetics Institute say this …

Three cloned babies born: Italian Doc

Maverick Italian fertility doctor Severino Antinori said that three babies had been born from cloned embryos in reproduction experiments. In May 2002, he had said three women were pregnant with clones. In November of the same year, he said a woman pregnant with a cloned embryo was due to give …

Home Office `running scared` on horse cloning

A leading reproductive scientist claims the government is running scared of animal rights campaigners after blocking efforts to clone horses. Twink Allen, director of the Equine Fertility Unit in Newmarket and professor of equine reproduction at Cambridge University, applied to implant cloned embryos into female horses three years ago, but …

Parents with sick kids turning to siblings` stem cells

Couples who need a stem cell donor for a child desperately ill with leukemia or anemia are turning to reproductive genetics clinics to help them conceive one, says a report Wednesday about the controversial approach. Some ethicists have expressed concern about using technology to create children who would be tissue …

Electric shock: Copper power drives all life processes

The human cell is literally wired with copper to deliver the electrical power that drive all life processes, new research has shown. A University of Leicester research team has investigated the processes by which electricity is generated within the body - by analysing how copper is distributed in the human …

The generation gap

researchers from the us-based Purdue University have discovered a paradox that could crop up if genetically modified (gm) fish are released into the wild. While gm fish are bigger and have more success at attracting mates, they produce offspring that are less likely to reach to adulthood, the researcher found. …

Radical theory

four billion years ago, the Moon orbited much closer to the Earth than it does now, causing massive tides to flow every few hours. These tides could have led to the evolution of early dna-like molecules. Richard Lathe of the uk-based organisation Pieta Research has recently propounded this hypothesis in …

Cancer fighter

scientists have finally established how a cell molecule combats unhealthy functioning of the human body with the help of the gene silencing process. During the process, functioning of genes in specific cells can be suppressed with the help of ribonucleic acid (rna)

Study finds signs of life in ancient lava

Tiny, bacteria-like organisms made their home in hardened lava some 3.5 billion years ago, scientists reported last week in a finding that pushes the limits of when life is known to have started on Earth. The microbes, known as archaea, dug into volcanic rock to form long tubes. A team …

Mice born in Japan from female genes

Scientista in Japan have demonstrated for the first time how mammals can reproduce without a male, leading to the birth of apparently healthy baby mice by mixing two sets of female genes inside an egg. Experts said that it will be a long time before men are relegated to the …
