Plant study hints evolution may be predictable
Updated : 3 years, 3 months ago IST
Evolution has long been viewed as a rather random process, with the traits of species shaped by chance mutations and environmental events and therefore largely unpredictable.

Venom in snakes and salivary protein in mammals share a common origin: Stu
Updated : 3 years, 3 months ago IST
Snakes, some lizards and even a few mammals can have a venomous bite. Although these lineages split more than 300 million years ago, their venoms have evolved from the same ancestral salivary protein, reported scientists today in BMC Biology.

Human evolution wasn't just sheet music, but how it was played: Research
Updated : 3 years, 3 months ago IST
A team of Duke researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.

Sea trial shows 'SharkGuard' reduces bycatch of endangered sharks
Updated : 3 years, 3 months ago IST
For sharks living in the open ocean, longline fishing is the number-one threat, with an estimated 20 million pelagic sharks caught annually by fishers looking for tuna and other desired species. Now, a new study reported in Current Biology on November 21 shows that a new technology, known as

Study: CAR T cell therapy reaches beyond cancer
Updated : 3 years, 3 months ago IST
Engineered immune cells, known as CAR T cells, have shown the world what personalized immunotherapies can do to fight blood cancers. Now, investigators have reported highly promising early results for CAR T therapy in a small set of patients with the autoimmune disease lupus. Penn Medicine C

Genetic links between traits often overstated: Research
Updated : 3 years, 4 months ago IST
Genetic correlation estimates typically assume that mating is random. But in the real world, partners tend to pair up because of many shared interests and social structures.

Study finds that children learn more quickly than adults
Updated : 3 years, 4 months ago IST
If you've ever had the feeling that your elementary school kids were "smarter" than you or at least capable of picking up new information and skills faster, a new study in Current Biology on November 15 suggests you're absolutely right.

Researchers identify protein that contributes to tau neurotoxicity in Alzh
Updated : 3 years, 4 months ago IST
Researchers from Indiana University School of Medicine have identified a protein that interacts and enhances the spread of neurotoxic species of tau which is primarily found in neurons that appear abnormal in the brains of Alzheimer's disease patients.

Researchers discover how cancer cells 'decide' to grow, spread
Updated : 3 years, 4 months ago IST
A recent study has found that membrane voltage being higher than in healthy cells it also fluctuates over time - with breast cancer cells behaving much like neurons.

Study suggests fish's quirky behaviour helps them estimate swimming direct
Updated : 3 years, 4 months ago IST
According to new simulations, fish glance down when swimming because the stable riverbed underneath them provides more trustworthy information about their swimming direction and speed.
