A medication commonly taken for Type II diabetes, which is being found in freshwater systems worldwide, has been shown to cause intersex in fish -male fish that produce eggs.
France said Friday it has approved increased fishing of tiger and bull sharks in the marine reserve of its African island territory of Reunion after a teenage surf star was killed.
A new hybrid plant used in anti-malarial drug production, developed by scientists at the University of York’s Centre for Novel Agricultural Products (CNAP), is now registered as a new variety in China.
A team of Belgian philosophers and plant biotechnologists have turned to cognitive science to explain why opposition to genetically modified organisms (GMOs) has become so widespread, despite positive contributions GM crops have made to sustainable agr…
Functional analysis of a cell, which is the fundamental unit of life, is important for gaining new insights into medical and pharmaceutical fields. For efficiently studying cell functions, it is essential to reconstruct cellular microenvironments by pa…
Researchers have discovered that a cascade activation of several molecules triggered by the ATM protein regulates DNA repair during the production of spermatocytes by meiosis, the cell division process which yields spermatozoa.
The European Union has authorized the use of more genetically modified food and feed amid a row over whether EU member states should be able to independently ban certain GM products.
WAMSI is making big data a key point in its Blueprint for Marine Science 2050, an initiative that will benefit researchers, governments, industry and the environment.
A team at the Institut de Génétique et de Biologie Moléculaire et Cellulaire (IGBMC – CNRS/Université de Strasbourg/Inserm) has evidenced, at the atomic scale, the three-dimensional structure of the complete human ribosome and the detailed interactions that occur within it. These findings, obtained using a technology that is unique in France, open the way to further exploring some of the adverse effects of antibiotics, and, in the longer term, to the treatment of diseases related to ribosomal dysfunctions and the deregulation of protein synthesis. This work is published in Nature on 22 April 2015.
For decades scientists have been looking closely at how our cells make proteins. But the inverse is equally important: how cells kill them.
Once upon a time, scientists thought RNA polymerase—the molecule that kicks off protein synthesis by transcribing DNA into RNA—worked like a wind-up toy: Set it down at a start site in our DNA and it would whir steadily along, reeling off an RNA copy, until it reached the stop site.
The establishment of symbiotic systems requires one organism to live in or on a host. For some North American amphibians, these symbionts are algae and they associate with their aquatic egg masses. Researchers have begun to speculate that these smaller…
Thai wildlife officials began a headcount Friday of nearly 150 tigers kept by monks at a temple which has become the centre of a dispute over the welfare of the animals.
A new study of the complex interplay between organisms and their environment shows that biodiversity—the variety of organisms living on Earth—is even more important to the healthy functioning of ecosystems than previously thought.
There was a time when Khorn Savai avoided caterpillars, convinced they would make her ill. Now she actively seeks them out.
Think Jaws meets a kangaroo, with maybe a touch of cute kitten, and you’ve got the aptly named pocket shark—the newest and rarest species found off the U.S. coast.
Many loggerhead sea turtles that nest in Dry Tortugas National Park head to rich feeding sites in the Bahamas after nesting, a discovery that may help those working to protect this threatened species.
New genetic data suggest the red lionfish invasion in the Caribbean Basin and Western Atlantic started in multiple locations, not just one as previously believed, according to a new study led by the U.S. Geological Survey.
