Scientists have found that a process in cells may limit infectivity of SARS-CoV-2, and that mutations in the alpha and delta variants overcome this effect, potentially boosting the virus's ability to spread.
New data shows how inflammatory reactions can be resolved by changes to the metabolism of macrophages. Danger signals released by damaged cells during inflammation play a role during this process. 'Rewiring' the mitochondria in the macrophages protects them against overloading and can thus improve the way in which parts of damaged cells are eliminated and resolve the inflammatory reaction.

New discoveries are constantly reshaping and enriching the story of our pastThe novelist and philosopher Iris Murdoch once wrote that the study of early Greek history “sets a special challenge to the disciplined mind. It is a game with very few pieces, where the skill of the player lies in complicating the rules.” The same could be said of the study of Britain’s Roman period, a long, often...
In October, the major employment indicators for people with disabilities reached their highest recorded levels since September 2008, when reporting for this cohort was begun by the Bureau of Labor Statistics (BLS), according to today's National Trends in Disability Employment—Monthly Update (nTIDE), issued by Kessler Foundation and the University of New Hampshire's Institute on Disability...
Jewelers, geologists, and microscopists agree: diamonds are forever. Researchers at the University of Illinois Urbana-Champaign are using microscopic nanodiamonds to calibrate and assess the performance of high-powered microscopes. Their longevity and durability make the tiny "first-aid kits" more than up to the task.
Princeton researchers have solved a 54-year-old puzzle about why certain fluids strangely slow down under pressure when flowing through porous materials, such as soils and sedimentary rocks. The findings could help improve many important processes in energy, environmental and industrial sectors, from oil recovery to groundwater remediation.
With the eyes of the world on the United Nations COP26 climate summit in Glasgow, Scotland, strategies for decarbonizing energy infrastructure are a trending topic. Yet critics of renewables question the dependability of systems that rely on intermittent resources.
An international research team has demonstrated a completely novel state of matter in a metal. It is created by the combination of four electrons-until now, only electron pairs were known. This discovery could lead to a new type of superconductivity, an entirely new research direction, and revolutionary technologies such as quantum sensors.
It is essential for cells to control precisely which of the many genes of their genetic material they use. This is done in so-called transcription factories, molecular clusters in the nucleus. Researchers have now found that the formation of transcription factories resembles the condensation of liquids. Their findings will improve the understanding of causes of diseases and advance the development...
A new study has identified an RNA molecule that suppresses prostate tumors. The scientists found that prostate cancers develop ways to shut down this RNA molecule to allow themselves to grow. According to the new research -- conducted in mice implanted with human prostate tumor samples -- restoring this so-called long noncoding RNA could be a new strategy to treat prostate cancer that has...
In a new study, researchers compared domesticated rice to its wild counterparts to understand the differences in their photosynthetic capabilities. The results can help improve future rice productivity.
Researchers have discovered a novel way to manipulate defects in semiconductors. The study holds promising opportunities for novel forms of precision sensing, or the transfer of quantum information between physically separate qubits, as well as for improving the fundamental understanding of charge transport in semiconductors.
Researchers have discovered a new approach for using visible-light to structurally modify bioactive molecules in chemical reactions, providing a possible sustainable alternative to traditional methods that could be used in the design and production of new medicines.

For a century and a half, melting snow and ice have been the most recognizable visual evidence of climate change. You can see it in the Arctic Ocean, where the first ice-free summer in two and a half million years is predicted by 2035; in the Alps, where half of the range’s iconic glacial ice…
When was the last time an asteroid hit Earth? Small asteroids and other tiny particles bombard our planet daily, but almost all of them burn up safely in the atmosphere. Bigger impacts are extremely rare, but scientists like Marina Brozovic are keeping their eyes on the sky.

A new study strengthens the case that climate change has been the main cause of the growing amount of land in the western U.S. destroyed by large wildfires. And researchers say the trend is likely to worsen.
With the United Nations climate conference in Glasgow, the world is focused on the consequences of a climate crisis and how we can still change course. Yet while climate-driven migration has been deemed a major threat in public discourse and academic research, comprehensive studies that take into account both environmental and social factors globally have been scarce. Now, with the help of machine...
When listening closely, the melodies of human languages and animal vocalizations are very similar. However, it is not yet fully resolved if similar patterns in languages and animal vocalizations also have similar meanings. Researchers of the University of Vienna present a new method to decode the meaning of animal vocalizations: the comparison of their melodies with human languages. The proposal...
A new article co-authored by King's academic Professor Andrew Blick argues that—while there is no doubt that the circumstances of the pandemic called for exceptional safeguarding measures—established contingencies legislation would have served as a better framework.
Ultra-diffuse galaxies (UDGs) have very low luminosities, comparatively few stars, and little star-formation activity as compared with normal galaxies of similar sizes. Commonly found in galaxy clusters, UDGs come in a wide range of sizes and shapes, many of them being round and smooth like dwarf elliptical galaxies, others showing distorted shapes from having experienced tidal disruptions; some...
Recently, researchers developed high-performance solar thermal copper sulfide photothermal ink and photothermal film, marking big progress in the field of Plasmonic Solar photothermal Materials.
A NASA sounding rocket will observe a nearby star to learn how starlight affects the atmospheres of exoplanets—key information in the hunt for life outside our solar system.
As forests age, differences in species functional traits become more important and reliable in predicting forest productivity, according to an international study led by Prof. Ma Keping at the Institute of Botany of the Chinese Academy of Sciences (IBCAS).
Treating diseases such as Alzheimer's or Parkinson's is a challenge because drugs have to be able to cross the blood–brain barrier. As a result, the doses administered must be high and only a small fraction reaches the brain, which can lead to significant systemic side effects. To solve this issue, the postdoctoral researcher Jean-Michel Rabanel, under the supervison of Professor Charles...
Keen to do your bit for the environment? Cut back on sweets, pastries, fried foods and processed meat. According to a new study published this month, reducing these foods in our diet is not only better for our health but also the planet.
Pseudobulbs, which are somewhat enlarged or thickened succulent stems, are common in epiphytic orchids. Nitrogen can be transported from old to young pseudobulbs and between leaves and pseudobulbs.
If fulfilled, climate pledges made in the last six years have a much better chance of reaching globally agreed temperature goals.
Research by scientists from UCLA and Lawrence Livermore National Laboratory strengthens the case that climate change has been the main cause of the growing amount of land in the western U.S. that has been destroyed by large wildfires over the past two decades.
Eighty-seven percent of all researchers have a (very) positive attitude about open science. Young scientists are even more enthusiastic with a percentage of 94 percent. But researchers are still coming across obstacles when it comes to practical implementation. This has emerged from a poll commissioned by NWO among researchers from all disciplines.
Need another reason to cut back on sugary foods and drinks, apart from an expanding waistline? They're not helping the environment, contributing to a higher cropland, water scarcity and ecological footprint, according to a new review.
New research shows the lifelong toll that adverse events in childhood can take on your health.
Scientists have created a new technology that rapidly detects the SARS-CoV-2 virus. The new SENSR was developed using CRISPR gene-editing technology as a rapid diagnostic that eventually could be used in homes, airports and other locations.
The largest protein in the human body, titin, enables elastic movements of our muscles, including the heart. Mutations in the titin gene (TTN) that impair this function and lead to heart muscle disease. The pathomechanisms behind this -- i.e. why TTN mutations trigger disease -- were unclear until now. A team of experts has now investigated these pathomechanisms in more detail and has gained...
