How warm weather or bright lights can influence tree greening

Lin Meng has been named the grand prize winner of this year's Science & SciLifeLab Prize for Young Scientists for research she conducted on how both global warming and bright city lights can impact phenology in trees (when they begin to grow leaves in the spring). In her paper published in the journal Science, Meng outlines her study of satellite data showing green areas in cities along with...

US to restrict travel from southern Africa over Omicron Covid variant fears

WHO names variant found in Belgium and Israel Omicron White House adviser Fauci: no indication variant is in USBioNTech says vaccine can be tweaked in 100 days if neededJoe Biden’s chief medical adviser, Anthony Fauci, said on Friday there was “no indication” the new “Omicron” coronavirus variant discovered in southern Africa had reached the US.Nonetheless, the the Biden administration...

Researchers hope to breed Great Barrier Reef corals more resilient to extreme heat events – video

Researchers from the Australian Institute of Marine Science are hoping to breed corals that are more resilient to extreme heat events. The researchers collected hundreds of coral samples from the northern part of the Great Barrier Reef that have survived three mass bleaching events since 2016. The samples have to be collected before they spawn which occurs only once a year, several days after a...

COVID-19: The coronavirus's tangled strands of RNA could offer new ways to treat people who get infected

To the untrained eye, the loops, kinks and folds in the single strand of RNA that makes up the coronavirus genome look like a jumble of spaghetti or tangled yarn. But to researchers like Amanda Hargrove, a chemistry professor at Duke University, the complex shapes that RNA takes on as it folds upon itself could have untapped therapeutic potential in the fight against COVID-19.

The Guardian view on the Omicron variant: caution needed | Editorial

We do not yet know how much of a threat it poses, but the pandemic has already shown it is better to act earlyCoronavirus – latest updatesSee all our coronavirus coverageHearts are sinking. Many had hoped the worst of the pandemic was over, enjoying a return to quasi-normality despite warnings that this winter could prove punishing. Now Covid cases are surging across Europe; rates are rising in...

Researchers reconstruct historical non-growing-season precipitation in southeastern Tibetan Plateau

A joint research team led by researchers from the Xinjiang Institute of Ecology and Geography (XIEG) and the Research Center for Eco-Environmental Sciences (RCEES) of the Chinese Academy of Sciences has reconstructed the historical non-growing-season (from November of the previous year to February of the current year) precipitation in the southeastern Tibetan Plateau using tree rings.

Scientists fling model stars at a virtual black hole to see who survives

Watch as eight stars skirt a black hole 1 million times the mass of the Sun in these supercomputer simulations. As they approach, all are stretched and deformed by the black hole's gravity. Some are completely pulled apart into a long stream of gas, a cataclysmic phenomenon called a tidal disruption event. Others are only partially disrupted, retaining some of their mass and returning to their...

Study finds a growing appreciation of the benefits provided by hoofed animals

The benefits to humans most commonly associated with wild ungulates—such as deer, hippos, wild boar, or giraffes—are hunting (and the food-source it represents for many communities) and their aesthetic value. This is one of the conclusions of a scientific literature review led by researchers from the Ecology Area of the Miguel Hernández University of Elche (MHU), in which scientists from the...

Quantifying phosphorus needs of smallholder farms in tropical regions

Smallholder farms in tropical regions can double their crop production by 2030 compared to 2015, finds a study to which José Mogollón (Institute of Environmental Sciences) contributed. But to achieve this, the farmers must increase the input of phosphorus beyond what is currently foreseen. The study is published in Nature Sustainability.

Study links increasing air pollution to the rise of a type of lung cancer

An international team of scientists, led by Nanyang Technological University, Singapore (NTU Singapore), has linked increased air pollution to an uptick in cases of lung adenocarcinoma (LADC) worldwide. The same study also concluded an overall lower consumption of tobacco worldwide is statistically linked to less people contracting lung squamous cell carcinoma (LSCC).

New research reveals the mechanism of ion transport in aqueous lithium ion batteries

Lithium-ion batteries are notorious for being a fire hazard due to their flammable organic electrolytes. As such, there has been much effort to utilize water-based electrolytes as a safer alternative. However, this is hampered by the problem of water molecules undergoing electrolysis into hydrogen and oxygen within the battery, which causes various problems such as poor efficiency, short device...

Successful fertilization requires careful coordination of chromosomes

RIKEN researchers have shown how the genomic sorting that occurs during fertilization—the incorporation of genomic material from both parents and the elimination of excess maternal DNA from the egg—takes place in mice. If the same process occurs in humans, the finding could help to improve some assisted reproductive technologies.

Creating coherent device motion based on coordinated microscopic movements

Thanks to work by scientists from the RIKEN Center for Emergent Matter Science and collaborators, scientists are closer to creating devices that can use microscopic movements in a coordinated way to create coherent motion on a macroscopic scale. This replicates the way living organisms move in a different way from manmade mechanical devices.

Biologists reveal how obesity damages the skeletal muscle metabolism

A decline in metabolism and endurance of skeletal muscle is commonly observed in obese patients, but the underlying mechanism is not well-understood. A research team led by Dr. Chi Bun Chan, Assistant Professor from School of Biological Sciences, Faculty of Science, the University of Hong Kong (HKU), uncovers a new mechanism to explain how obesity jeopardizes the functions of skeletal muscle and...

The study of the microbiome enables new strategies for healthy and climate-resilient crops

Agriculture is facing enormous challenges worldwide due to global changes caused by human activities. Drought, severe weather events, record temperatures and emerging pathogens threaten the world's food supply. For this reason we need to make our crops more robust without further polluting the environment. Microbiome research and management offer great potential to achieve these goals. A new study...

A study reveals the presence of murine coronavirus in Canary Islands mice population

A study published in Frontiers in Veterinary Science reveals the presence of murine coronavirus—the murine hepatitis virus or M-CoV—in mice of the Canary archipelago (Spain) that could have reached the islands by maritime transport from the European continent. This is the first ecoepidemiological study to examine the presence of coronaviruses that circulate in mice and rats of the natural and...

Gliricidia intercropping in Zambia shows promising results

The species Gliricidiasepium is a deciduous tree, cultivated and used for a variety of purposes in tropical regions. In Zambia, it is used for timber, firewood, medicine, charcoal, living fences, and plantation shading. Additionally, both soil health and crop nutrition can be improved by the incorporation of the leguminous tree's leaf biomass.
