Significant increase in short-duration extreme precipitation over mountainous areas in China seen under global warming

A new study led by Prof. Xiaopeng Cui from the Institute of Atmospheric Physics at the Chinese Academy of Sciences, in collaboration with experts from the National Meteorological Center of China, has uncovered a startling trend of increased short-duration extreme precipitation over mountainous regions in Southwest China. These findings shed light on the pressing issue of climate change and its...

Northern peatlands in Finland are still expanding, finds study

According to a new study published in Global Change Biology, the area of northern peatlands has grown in recent centuries. Previously, it was thought that the lateral expansion of peatlands in Fennoscandia has halted or significantly slowed, as the flat areas susceptible to peat formation have already turned into peatland.

Study analyzes differences in canine teeth between European and African populations

The Dental Anthropology Group at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) has published a study in the journal Anthropological Science, in collaboration with the University of Bordeaux (France) and the University of Pretoria (South Africa), which analyzes the differences between the canines of European and African individuals.

Construction on NASA mission to map 450 million galaxies is under way

NASA's SPHEREx space telescope is beginning to look much like it will when it arrives in Earth orbit and starts mapping the entire sky. Short for Specto-Photometer for the History of the universe, Epoch of Reionization, and Ices Explorer, SPHEREx resembles a bullhorn, albeit one that will stand almost 8.5 feet tall (2.6 meters) and stretch nearly 10.5 feet (3.2 meters) wide. Giving the observatory...

How wealthy countries' research skews our knowledge of plants

More extreme weather and large variations in temperature and precipitation: Climate change affects not only humans and animals but also plants. They, too, face significant challenges, and there is increasing interest in creating climate models to calculate how the world´s plants will respond to a changing climate.

Endangered thick-billed parrots at risk of losing unprotected Sierra Madre forest habitats to logging, deforestation

A binational team of scientists, using creativity and innovation, adorned dozens of endangered thick-billed parrots with tiny solar-powered satellite transmitters to track and reveal their winter migratory nesting sites in the remote treetops of the Sierra Madre Occidental ranges. Their research reveals new critical habitat, 80% of which has no formal protection.

Scientists flag conflicts of interest ahead of UN plastic and chemical talks

An international group of 35 scientists is calling out conflicts of interest plaguing global plastic treaty negotiations and that have interfered with timely action on other health and environmental issues. They urge the implementation of strict guidelines to prevent the same problems from affecting the UN's upcoming Science Policy Panel on chemicals. Their concerns and recommendations are...

Water on asteroid Ryugu's parent found to have shaped distribution of its elements

A large international team of space scientists, geochemists, and engineers, has found that water that existed on the parent of Ryugu had an impact on the distribution of elements on the asteroid. In their paper published in the journal Science Advances, the group describes how they compared two isotopes of both chromium and titanium and what the differences they found told them about Ryugu's...

Researchers develop cheap and efficient ethanol catalyst from laser-melted nanoparticles

Ethanol fuel cells are regarded as promising sources of green electricity. However, expensive platinum catalysts are used in their production. Research on laser melting of suspensions carried out at the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow, has led researchers to materials that catalyze ethanol with a similar—and potentially even greater—efficiency to...

Study examines link between underwater landslides and tsunamis

Scientists have calculated a way to determine the speed of past underwater landslides. To do so, researchers from The Ohio State University studied the remains of an underwater landslide just off the coast of Oregon—dubbed the 44-N Slide—that is part of the Cascadia Subduction Zone (CSZ).

Biobased mulch spray curbs weeds in vegetable crops

Biobased sprayable mulch (BSM) films are a potential alternative to herbicides, polyethylene plastic mulch film, and hand weeding for specialty crops. Researchers at the American Society for Horticultural Science have developed a series of BSM films using locally available biomaterials and tested their effects on weeds and crop yield during a total of seven greenhouse or field trials between 2017...

Study reveals bacterial protein capable of keeping human cells healthy

Researchers at the University of São Paulo (USP) in Brazil, partnering with colleagues in Australia, have identified a novel bacterial protein that can keep human cells healthy even when the cells have a heavy bacterial burden. The discovery could lead to new treatments for a wide array of diseases relating to mitochondrial dysfunction, such as cancer and auto-immune disorders. Mitochondria are...

Pushing the limits of gas sensing technology

The world has become increasingly industrialized over the past few centuries, bringing all sorts of technology and conveniences to the masses. However, workers in industrial environments are often at risk of exposure to many dangerous gases, such as nitrogen dioxide (NO2). Inhaling this gas can lead to serious respiratory diseases like asthma and bronchitis, and severely compromise the health of...
