Researchers pin down long-elusive protein that's essential to 'life as we know it'
A team of researchers is being recognized for devising a new way to study a human protein that long has evaded close scrutiny by scientists investigating its role in the...
Giant river fish faces extinction
The arapaima, a giant Amazon river fish that can grow longer and heavier than a human adult, is at risk of extinction, according to a new study. Overfishing and errors in classification...
Virus may chauffeur useful 'packages' into plants
This time of year, the word "virus" conjures up a bedridden stint with coughs and chills -- something everyone goes to great lengths to avoid. But a new study shows...
Thai hill farmers help preserve genetic diversity of rice
Rice is one of the most important crops worldwide, as it feeds over half of the world's population. Domesticated rice is an important supply of the world's rice. However, these...
CSHL team determines how precursors of gene-regulating small RNAs are sorted by cellular machinery
A team of scientists at Cold Spring Harbor Laboratory (CSHL) has determined a hierarchical set of criteria that explain how the molecular precursors of gene-regulating small RNAs are sorted by...
MyoD helps stem cells proliferate in response to muscle injury
The master regulator of muscle differentiation, MyoD, functions early in myogenesis to help stem cells proliferate in response to muscle injury, according to researchers at Case Western Reserve University. The...
Five lung function genes found
An international team has discovered five common genetic variations that affect lung function and can lead to disease.
Photographed: Ratchet-Like Cell Mechanism that Pulls Wounds Shut
Closing Time: In this micrograph of dorsal closure in a fruit-fly embryo, the protein actin is marked red, prominent around the gap in the epithelial cells. The microtubules that give shape to...
Fossil reveals whale's origin
An Australian fossil has unlocked the secrets of whale evolution and provides new support for one of Charles Darwin's theories.
Demonstration of pH-regulating protein
Researchers have identified the protein mechanism that senses bicarbonate fluctuations and adjusts blood pH levels. Scientists have now achieved the first demonstration of the process in a whole animal. The...
Roe of marine animals is best natural source of omega-3
The roe of hake, lumpsucker and salmon is the best dietary source of omega-3, according to a new study. The scientists analyzed the eggs, or roe, of 15 marine animals,...
Biosensors offer brain insights
Scientists have developed biological cells that can give new insight into the chemistry of the brain.

Three new alkaloids found in winter snowdrop plants
Scientists have identified 17 bioactive compounds in winter snowdrops, the earliest flowering plants in Europe. Out of the alkaloids identified, three are new to science and belong to a group...
How ubiquitin chains are added to cell-cycle proteins: May lead to targeted cancer therapies
Researchers have been able to view in detail, and for the first time, the previously mysterious process by which long chains of a protein called ubiquitin are added by enzymes...
Brooding fishes take up nutrients from their own children
In the pipefish, the male cares for the offspring. Apart from the ones he sucks the life out of. Researchers have just discovery filial cannibalism in the pipefish.
Scientists say dolphins should be treated as 'non-human persons'
Dolphins have been declared the world’s second most intelligent creatures after humans, with scientists suggesting they are so bright that they should be treated as “non-human persons”.

Molecular anchor links the two inheritable diseases Fanconi anemia and Bloom's syndrome
A new study establishes a molecular link that bridges two rare inherited disorders and explains why these diseases result in genetic instability. The research may lead to a better understanding...
Scientists identify DNA that regulates antibody production
Performance enhancers are the currency of a competitive society. But there's one that we have always had: For millions of years, segments of our DNA have improved the performance of...
Two proteins act as molecular tailors in DNA repair
Every day tiny segments of our DNA are chipped or fragmented or get stuck together when they should really be pulled apart. But what our genome necessarily lacks in stability...
