DNA is often referred to as the blueprint for life, however scientists have for the first time discovered a microbe that uses two different translations of the DNA code at random. This unexpected finding breaks what was thought to be a universal rule, since the proteins from this microbe cannot be fully predicted from the DNA sequence.
Male mice grow ovaries instead of testes if they are missing a small region of DNA that doesn't contain any genes -- a finding that could help explain disorders of sex development in humans, at least half of which have an unknown genetic cause.
The world's system for allocating fish stocks is being outpaced by the movement of fish species in response to climate change, according to a study undertaken by an international team of marine ecologists, fisheries and social scientists, and lawyers.
Researchers have found a way to predict whether someone exposed to the flu virus is likely to become ill. They used a computational approach to pinpoint a blood-based genetic biomarker to determine an individual's susceptibility to the disease.
Scientists have reviewed decades of satellite measurements to reveal how and why Antarctica's glaciers, ice shelves and sea ice are changing. Their report explains how ice shelf thinning and collapse have triggered an increase in the continent's contribution to sea level rise.
Ice losses from Antarctica have increased global sea levels by 7.6 mm since 1992, with two fifths of this rise (3.0 mm) coming in the last five years alone. The findings are from a major climate assessment known as the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE). It is the most complete picture of Antarctic ice sheet change to date -- 84 scientists from 44 international organizations combined 24 satellite surveys to produce the assessment.
During the history of the Earth, there were many mass extinctions, when huge numbers of species died out. They are usually easy to identify because of the sudden extinctions, followed by a gap, and then the recovery of life.
Anders Behring Breivik, serving 21 years for killing 77 people in bomb, shooting rampage, said prison isolation violated his rights
