Scientists took a rare chance to prove we can quantify biodiversity by 'testing the water'

While extraction of DNA from water samples provides a convenient and non-invasive way to study aquatic biodiversity, reliable evidence that this approach is accurate enough to estimate the number of fish per species and their biomass in natural habitats, is still lacking. A new study, published in the open-access, peer-reviewed journal Metabarcoding and Metagenomics, demonstrates the high...

Thermal stability analysis technique for EV batteries to detect risk of fire or explosion

Recently, there have been a number of electric vehicle (EV) battery fire incidents. Unlike the batteries used in small mobile devices, such as smartphones, the battery pack of an EV is composed of hundreds of battery cells, and any instability can cause major casualties and property damage. Amid various efforts to pinpoint the cause of battery fires, Korean researchers have developed a new...


A new era is dawning in diagnosing sexually transmitted infections in men

Researchers and doctors from the University of Tartu and Tartu University Hospital evaluated the use of a novel revolutionary method, flow cytometry, for diagnosing urethritis in Estonian men. The study published in PLOS ONE confirmed the efficiency of the method and showed that most often urethritis was due to chlamydia. Gonorrhoea caused the strongest urethral inflammation.

A new view of how the brain decides to make an effort

Nature Human Behavior published the research by scientists at Emory University. It gives the first detailed view of ventral striatum activity during three phases of effort-based decision-making -- the anticipation of initiating an effort, the actual execution of the effort and the reward, or outcome, of the effort.

A plant immune receptor: It takes four to tango

A collaborative study on a plant intracellular immune receptor from researchers at the Max Planck Institute for Plant Breeding Research (MPIPZ) not only shows how an important resistance protein is activated during pathogen infection but also reveals some common operational principles with immunity proteins from humans.

Ancient migration was choice, not chance

The degree of intentionality behind ancient ocean migrations, such as that to the Ryukyu Islands between Taiwan and mainland Japan, has been widely debated. Researchers used satellite-tracked buoys to simulate ancient wayward drifters and found that the vast majority failed to make the contested crossing. They concluded that Paleolithic people 35,000-30,000 years ago must therefore have made the...

Can we make bones heal faster?

A new paper in Science Advances describes for the first time how minerals come together at the molecular level to form bones and other hard tissues, like teeth and enamel.

Clinical trial results address concerns about pharmacogenetic testing

Researchers conducted a randomized controlled trial of pharmacogenetic testing related to cholesterol-lowering medications called statins.After one year, the cholesterol levels in the group who received their pharmacogenetic results were not higher than those in the group who did not receive their results, and they were not less likely to receive medical care meeting recommended guidelines.

Cluster of Alaskan islands could be single, interconnected giant volcano

small group of volcanic islands in Alaska's Aleutian chain might be part of a single, undiscovered giant volcano, say scientists presenting the findings Monday, 7 December at AGU's Fall Meeting 2020. If the researchers' suspicions are correct, the newfound volcanic caldera would belong to the same category of volcanoes as the Yellowstone Caldera and other volcanoes that have had super-eruptions...

Coasts drown as coral reefs collapse under warming and acidification

The coastal protection coral reefs currently provide will start eroding by the end of the century, as the world continues to warm and the oceans acidify. The rate of erosion of calcium carbonate on coral reefs will overtake the rate of accretion on the majority of present-day reefs by the end of the century.
