Self-restrained genes enable evolutionary novelty

Changes in the genes that control development can potentially make large contributions to evolution by generating new morphologies in plants and animals. However, because developmental genes frequently influence many different processes, changes to their expression carry a risk of “collateral damage”. Scientists at the Max Planck Institute for Plant Breeding Research in Cologne, and collaborators, … Read more

American University researchers sequence genome of the ‘devil worm’

When scientists discovered a worm deep in an aquifer nearly one mile underground, they hailed it as the discovery of the deepest-living animal ever found. Now American University researchers, reporting in Nature Communications, have sequenced the genome of the unique animal, referred to as the ‘Devil Worm’ for its ability to survive in harsh, subsurface conditions. … Read more

Scientists first to develop rapid cell division in marine sponges

Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture and toxicology. Cell lines have been established for many organisms, including freshwater and terrestrial invertebrates. Despite many efforts over multiple decades, there are still no cell lines for marine invertebrates including marine sponges, … Read more

Underwater robotic gliders provide key tool to measure ocean sound levels

At a time when ocean noise is receiving increased global attention, researchers at Oregon State University and NOAA have developed an effective method to use an underwater robotic glider to measure sound levels over broad areas of the sea. “Healthy marine ecosystems need to have noise levels within particular ranges,” said Joe Haxel, an assistant … Read more

Western-led research team extends life of rechargeable batteries

Researchers from Western University, using the Canadian Light Source (CLS) at the University of Saskatchewan, found that adding a carbon-based layer to lithium-ion rechargeable batteries extends their life up to 50 per cent. The finding, recently published in the journal ACS Applied Materials and Interfaces, tackles a problem many consumers face: rechargeable batteries gradually hold … Read more

Melting Mongolian ice patches may threaten reindeer pastoralism, archaeological artifacts

Northern Mongolian “eternal ice” is melting for the first time in memory, threatening the traditional reindeer-herding lifestyle and exposing fragile cultural artifacts to the elements, according to a study published November 20, 2019 in the open-access journal PLOS ONE by William Taylor from the Max Planck Institute, Germany, and the University of Colorado-Boulder, USA, and colleagues. The … Read more

An ancient snake’s cheekbone sheds light on evolution of modern snake skulls

New research from a collaboration between Argentinian and University of Alberta palaeontologists adds a new piece to the puzzle of snake evolution. The researchers examined a strikingly well-preserved fossil of the rear-limbed snake Najash rionegrina, found in Argentina. The study shows that nearly 100 million years ago, these legged snakes still had a cheekbone – … Read more

3D maps of gene activity

A three-dimensional computer model enables scientists to quickly determine which genes are active in which cells, and their precise location within an organ. A team led by Nikolaus Rajewsky, Berlin, and Nir Friedman, Jerusalem, has published the new method and their insights based on this in Nature. Professor Nikolaus Rajewsky is a visionary: He wants … Read more
