The first MiG-29KUB carrier-based fighter developed for the Indian Navy took off at the Russian Zhukovsky aircraft test centre on January 22.

Demand from rich Chinese for Indian tiger pelts and parts used in traditional medicine fuels poaching and may lead to the extinction of the species in the wild, conservationists have warned.

Trade of tiger pelts from India into Chinese-ruled Tibet was flourishing despite laws banning the move, a report released in New Delhi by two conservation groups said Wednesday.

The Wildlife Protection Agency and Environment Investigation Agency estimate only 1,500 to 2,000 wild Royal Bengal Tigers are left in India.

The first public revelation of the earliest continuous Semitic text ever deciphered has taken place at the Hebrew University of Jerusalem.

If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke.

Why are males larger than females in some animal species (such as most mammals), females larger than males in others (such as most insects), and why are the sexes alike in yet other species (such as several birds)? Further, how is such sexual size dimorphism achieved when it exists? If males and females grow at the same rate, then the larger sex has to extend its growth period. Alternatively, the larger sex can grow faster.

Smooth as silk. Warm as wool; ______ as wheat gluten. Marketing specialists may be challenged to fill in that blank in the future, now that scientists in Nebraska report the first successful production of high-quality fibers from wheat gluten, that grain's major protein.

While robots have moved from the realm of science fiction to a myriad of real-life uses, the potential of the "hard-bodied" robots of the 21st century remains limited by their stiff construction and lack of flexibility. A group of researchers at Tufts University has launched a multidisciplinary initiative focused on the science and engineering of a new class of robots that are completely soft-bodied. These devices will make possible advances in such far flung arenas as medicine and space exploration.

On Saturday, Hubble's main camera, the Advanced Camera for Surveys (ACS), stopped working. Until a solution, at least in part, can be found, Hubble will be returned to work with the remaining instruments.
