DNA breakthrough detects genetic diversity of invasive fish: Research
Updated : 2 years, 6 months ago IST
Ecologists have proven that the genetic material that species shed into their environments can reveal not only the presence of the species but also a wide range of information about the genetics of whole populations — information that may assist scientists to trace the source of a new invasi

Study reveals how immune system trip wire that detects COVID-19
Updated : 2 years, 9 months ago IST
Inflammasomes are part of a complex network of molecular sensors that our bodies utilise to detect infection. However, immunologists have been intrigued by the processes behind these sensors, which activate responses to dangers such as invading infections.

Older trees accrue more mutations than their younger ones: Study
Updated : 2 years, 9 months ago IST
Older, long-lived trees are thought to contribute more to the creation and maintenance of genetic diversity than young, short-lived trees, according to research on the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate.

Study: Blending pairing of alleles has moulded human ancestry
Updated : 2 years, 9 months ago IST
Complex patterns of migration, isolation, and admixture--a phrase used to describe the exchange of genes between members of various populations--have characterised human history. As a result of the mixing of genetic lineages during admixture, populations' genetic diversity increases. Ancient

Research claims prehistoric human migration in Southeast Asia driven by se
Updated : 3 years ago IST
An interdisciplinary team of scientists at Nanyang Technological University, Singapore (NTU, Singapore) found that rapid sea-level rise prompted early settlers in Southeast Asia to migrate during the prehistoric period, increasing the genetic diversity of the region today.

Modern bread wheat originated around 10,000 years ago: Study
Updated : 6 years, 10 months ago IST
Washington D.C. [USA], May 5 (ANI): After mapping the genome of wheat, scientists have reconstructed its breeding history. They examined the genetic diversity of wheat varieties and discovered which cereals our ancestors cultivated, where today's wheat comes from, and what the Cold War ha
