Pulling the tablecloth out from under essential metabolism

Plants & Animals - 星期二, 06/27/2017 - 00:46
Most organisms share the biosynthetic pathways for making crucial nutrients because it is is dangerous to tinker with them. But now a collaborative team of scientists has caught plants in the process of altering where and how cells make an essential amino acid.

Cloning thousands of genes for massive protein libraries

Plants & Animals - 星期二, 06/27/2017 - 00:46
Discovering the function of a gene requires cloning a DNA sequence and expressing it. Until now, this was performed on a one-gene-at-a-time basis, causing a bottleneck. Scientists have invented a technology to clone thousands of genes simultaneously and create massive libraries of proteins from DNA samples, potentially ushering in a new era of functional genomics.

Peanut family secret for making chemical building blocks revealed

Plants & Animals - 星期二, 06/27/2017 - 00:45
The peanut and its kin -- legumes -- have not one, but two ways to make the amino acid tyrosine. That might seem small, but why this plant family has a unique way to make such an important chemical building block is a mystery that extends back to the 1960s.

New tool to identify and control neurons

Plants & Animals - 星期二, 06/27/2017 - 00:45
One of the big challenges in the neuroscience field is to understand how connections and communications trigger our behavior. Researchers have now developed a tool to identify and control neurons. The new technique, called Calcium and Light-Induced Gene Handling Toolkit or 'Cal-Light,' allows researchers to observe and manipulate the neural activities underlying behavior with never-before-seen specificity, hopefully allowing researchers to identify causality between neuronal activity and behavior.

Biodiversity loss from deep-sea mining will be unavoidable

Earth & Climate - 星期二, 06/27/2017 - 00:45
Biodiversity losses from deep-sea mining are unavoidable and possibly irrevocable, an international team of scientists, economists and lawyers argue. They say the International Seabed Authority, which is responsible for regulating undersea mining in areas outside national jurisdictions, must recognize the risk and communicate it clearly to member states and the public to spur discussions as to whether deep-seabed mining should proceed, and if so, what safeguards are needed to minimize biodiversity loss.

Vinegar: A cheap and simple way to help plants fight drought

Earth & Climate - 星期二, 06/27/2017 - 00:45
Researchers have discovered a new, yet simple, way to increase drought tolerance in a wide range of plants. The study reports a newly discovered biological pathway that is activated in times of drought. By working out the details of this pathway, scientists were able to induce greater tolerance for drought-like conditions simply by growing plants in vinegar.

Monitoring changes in wetland extent can help predict the rate of climate change

Earth & Climate - 星期二, 06/27/2017 - 00:45
Monitoring changes to the amount of wetlands in regions where permafrost is thawing should be at the forefront of efforts to predict future rates of climate change, new research shows.

New mechanism for bacterial division discovered in some bacteria

Plants & Animals - 星期二, 06/27/2017 - 00:45
Scientists show how some pathogenic bacteria -- such as the mycobacteria that cause tuberculosis -- use a previously unknown mechanism to coordinate their division. The discovery could help develop new ways to fight them.

How sex 'blindspot' could misdirect medical research

Plants & Animals - 星期二, 06/27/2017 - 00:45
The sex of animals frequently has an effect in biomedical research and therefore should be considered in the study of science, report scientists. In the largest study of its kind, researchers found that the differences between male and female mice had an effect that could impact research results in more than half of their studies.

Characterizing the mouse genome reveals new gene functions and their role in human disease

Plants & Animals - 星期二, 06/27/2017 - 00:44
The first results from a functional genetic catalogue of the laboratory mouse has been shared with the biomedical research community, revealing new insights into a range of rare diseases and the possibility of accelerating development of new treatments and precision medicine.

Previously unknown extinction of marine megafauna discovered

Plants & Animals - 星期二, 06/27/2017 - 00:44
Over two million years ago, a third of the largest marine animals like sharks, whales, sea birds and sea turtles disappeared. This previously unknown extinction event not only had a considerable impact on the earth's historical biodiversity but also on the functioning of ecosystems.

Microplastics sloughed from synthetic fabrics in the washing machine

Earth & Climate - 星期二, 06/27/2017 - 00:43
Billions of pieces of plastic are floating in the oceans. Their effects are also sufficiently well-known: marine animals swallow them or get tangled up in them, which can cause them to die in agony. On the other hand, we know less about the consequences of the smallest pieces of plastic, known as microplastics. Researchers have now started to investigate how microplastics are generated and where they actually come from.
