Stress may protect—at least in bacteria

Antibiotics harm bacteria and stress them. Trimethoprim (TMP), an antibiotic, inhibits the growth of the bacterium Escherichia coli and induces a stress response. This response also protects the bacterium from subsequent deadly damage from acid. Show More Summary

Purging the body of 'retired' cells could reverse ageing, study shows

Findings raise possibility that a future therapy that rids the body of senescent cells might protect against the ravages of old age Purging retired cells from the body has been shown to undo the ravages of old age in a study that raises the prospect of new life-extending treatments.

Dairy farmers should rethink a cow's curfew, says UBC researchers

(University of British Columbia) Dairy cows housed indoors want to break curfew and roam free, suggests new research from the University of British Columbia, published today in Scientific Reports.

How chewing like a cow helped early mammals thrive

(University of Chicago Medical Center) In a paper published March 21, 2017, in Scientific Reports, David Grossnickle, a graduate student in the Committee on Evolutionary Biology at the University of Chicago, proposes that mammal teeth,...Show More Summary

SPICY: Discovery of new ginger species spices up African wildlife surveys

(Wildlife Conservation Society) Scientists from WCS have discovered a new species of wild ginger, spicing up a wave of recent wildlife discoveries in the Kabobo Massif -- a rugged, mountainous region in Democratic Republic of Congo.

New stem cell method produces millions of human brain and muscle cells in days

(Wellcome Trust Sanger Institute) Wellcome Trust Sanger Institute scientists and their collaborators at the University of Cambridge have created a new technique that simplifies the production of human brain and muscle cells -- allowing millions of functional cells to be generated in just a few days.

New tools to study the origin of embryonic stem cells

Researchers at Karolinska Institutet have identified cell surface markers specific for the very earliest stem cells in the human embryo. These cells are thought to possess great potential for replacing damaged tissue but until now have been difficult to distinguish from classical embryonic stem cells. The study is published in the prestigious journal Cell Stem Cell.

Research shows that circular RNAs, until now considered non-coding, can encode for proteins

A group of scientists in Israel and Germany, led by Prof. Sebastian Kadener from the Hebrew University of Jerusalem, have discovered a protein-encoding function for circular RNA. This kind of RNA molecule is highly active in brain cells and could play an important role in neurodegenerative diseases.

Membrane lipids hop in and out of rafts in the blink of an eye

Researchers in Japan, India and France have found that molecules move into and out of a specialized region of the cell membrane, called the 'raft domain', at unexpectedly fast rates. The discovery was made possible by developing fluorescent...Show More Summary

Diabetes damages small coronary blood vessels and thus increases the risk of heart attacks

(Technical University of Munich (TUM)) Diabetics have a significantly higher risk of suffering a heart attack. A research team at the Technical University of Munich (TUM) has now identified one of the causes: Diabetes is associated with the loss of small blood vessels around the heart. Show More Summary

The Anthropocene: Scientists respond to criticisms of a new geological epoch

(University of Leicester) 'Irreversible' changes to the Earth provide striking evidence of new epoch, University of Leicester experts suggest.

Membrane lipids hop in and out of rafts in the blink of an eye

(Kyoto University) New fluorescent lipids demonstrate how specialized regions in the cell membrane function.

Corals die as global warming collides with local weather in the South China Sea

(Woods Hole Oceanographic Institution) In the South China Sea, a 2°C rise in the sea surface temperature in June 2015 was amplified to produce a 6°C rise on Dongsha Atoll, a shallow coral reef ecosystem, killing approximately 40 percent of the resident coral community within weeks, according to a study published in Scientific Reports this week.

Livestock grazing effects on sage-grouse

(US Geological Survey) Effects of livestock grazing on greater sage-grouse populations can be positive or negative depending on the amount of grazing and when grazing occurs, according to research published today in Ecological Applications.

Research shows some viruses can infect even after major mutations

Portland State University researchers have found that only about half the genes in a specific virus affecting single cell organisms is needed to infect a host. This means the virus can undergo major mutations without losing its ability to survive and infect.

Non-breeding ravens live in highly dynamic social groups

Ravens have impressive cognitive skills when interacting with conspecifics – comparable to many primates, whose social intelligence has been related to their life in groups. An international collaboration of researchers led by Thomas...Show More Summary

Single nucleotide change responsible for allowing H7N9 flu to jump from birds to humans found

(Phys.org)—A team of researchers affiliated with several institutions in Hong Kong and mainland China has isolated a change in a single nucleotide that is responsible for allowing the H7N9 flu virus to replicate in both birds and humans. Show More Summary

Study reveals mass extinction event 35 million years ago

Australian National University biologists have found the first evidence of mass extinction of Australian animals caused by a dramatic drop in global temperatures 35 million years ago.

New tools to increase the accuracy of biodiversity monitoring

An EU funded project, has created a range of tools to give a more accurate picture of current biodiversity, aiding efforts for sustainable governance of natural resources.

A new web of life

For the first time biologists have made a full family tree of the world's spiders, giving us knowledge about venoms that can be useful in medicine. And we might be able to develop silk just as good as the spider's.
