Scientists map structure of potent antibody against coronavirus

Science Daily - 28/10/2020
Scientists have shown that a potent antibody from a COVID-19 survivor interferes with a key feature on the surface of the coronavirus's distinctive spikes and induces critical pieces of those spikes to break off in the process.

Beaches can survive sea-level rises as long as they have space to move

Science Daily - 27/10/2020
An international team of coastal scientists has dismissed suggestions that half the world's beaches could become extinct over the course of the 21st century.

Tailoring 2D materials to improve electronic and optical devices

Science Daily - 27/10/2020
New possibilities for future developments in electronic and optical devices have been unlocked by recent advancements in two-dimensional (2D) materials.

Scientists use clues in the human genome to discover new inflammatory syndrome

Science Daily - 27/10/2020
Researchers have discovered a new inflammatory disorder called vacuoles, E1 enzyme, X-linked, autoinflammatory and somatic syndrome (VEXAS), which is caused by mutations in the UBA1 gene. VEXAS causes symptoms that included blood clots in veins, recurrent fevers, pulmonary abnormalities and vacuoles (unusual cavity-like structures) in myeloid cells.

How to design organic solar cell materials

Science Daily - 27/10/2020
Scientists have recently scrutinized organic solar cells and derived design rules for light-absorbing dyes that can help to make these cells more efficient, while tailoring the absorption spectrum of the cells to the needs of the chosen application.

Empathy may be in the eye of the beholder

Science Daily - 27/10/2020
Do we always want people to show empathy? Not so, said researchers. A recently published article suggests that although empathy is often portrayed as a virtue, people who express empathy are not necessarily viewed favorably.

Cancer treatment without side effects?

Science Daily - 27/10/2020
Treating cancer without debilitating side effects has long been the holy grail of oncologists, and researchers may have found it.

Antarctica yields oldest fossils of giant birds with 21-foot wingspans

Science Daily - 27/10/2020
Some of the largest birds in history, called pelagornithids, arose a few million years after the mass extinction that killed off the dinosaurs and patrolled the oceans with giant wingspans for some 60 million years. A team of paleontologists has found two fossils -- each from individual pelagornithids with wingspans of 20 feet or more -- that show this gigantism arose at least 50 million years ago and lasted at least 10 million years.

Photovoltaics industry can help meet Paris agreement targets

Science Daily - 27/10/2020
To meet the Paris Agreement's goal of preventing Earth's average temperature from rising more than 2 degrees Celsius above preindustrial level, one of the best options for the energy economy will involve a shift to 100% renewable energy using solar energy and other clean energy sources. Researchers describe a model developed to predict what is necessary for the solar industry to meet Paris Agreement targets.

Promising strategies for durable perovskite solar cells

Science Daily - 27/10/2020
Perovskite materials are increasingly popular as the active layer in solar cells, but internal forces in these materials cause distortions in their crystal structures, reducing symmetry and contributing to their intrinsic instability. Researchers examined the mechanisms at play, as well as several degradation factors that influence the performance of perovskite photovoltaics. They clarified the factors influencing the degradation and they summarized some feasible approaches for durable perovskite photovoltaics.

'Fast' MRI detects breast cancers that 3-D mammograms may miss

Science Daily - 27/10/2020
In a retrospective study of asymptomatic patients, all of whom had a negative 3-D mammogram within the previous 11 months, abbreviated MRI detected roughly 27 cancers per 1,000 women screened.

What do breast cancer cells feel inside the tumor?

Science Daily - 27/10/2020
Using a new technique, a team of researchers has found tiny and previously undetectable 'hot spots' of extremely high stiffness inside aggressive and invasive breast cancer tumors. Their findings suggest, for the first time, that only very tiny regions of a tumor need to stiffen for metastasis to take place. Though still in its infancy, the researchers believe that their technique may prove useful in detecting and mapping the progression of aggressive cancers.

Aerosol microdroplets inefficient carriers of COVID-19 virus

Science Daily - 27/10/2020
Aerosol microdroplets do not appear to be extremely efficient at spreading the virus that leads to COVID-19. While the lingering microdroplets are certainly not risk-free, due to their small size they contain less virus than the larger droplets that are produced when someone coughs, speaks, or sneezes directly on us, said researchers.

Random effects key to containing epidemics

Science Daily - 27/10/2020
Scientists have discovered why dividing a large population into multiple subpopulations that do not intermix can help contain outbreaks without imposing contact restrictions within those local communities.

Black Hispanic individuals hardest hit by COVID-19

Science Daily - 27/10/2020
A new study shows the disproportionate impact of COVID-19 on Hispanic groups within the United States, with the most severe outcomes, including death and intensive care, among Hispanic Black individuals.

Proton regulator of essential cancer microRNA

Science Daily - 27/10/2020
New findings unveil that a 'hidden' layer of regulation by which the intrinsic dynamic ensemble of miRNA processing intermediates can direct the outcome of important biological processes in response to environmental and cellular stimuli in the absence of protein factors. If these processes go awry, then disease could result. Understanding the roles of miRNAs in disease is a needed step in finding new routes to better therapeutics.

Death rates among people with severe COVID-19 drop by a half in England

Science Daily - 27/10/2020
Death rates from people with severe COVID-19 in hospital have dropped to around a half of the rate at the peak of the pandemic, new research has revealed.

Gran Telescopio Canarias finds the farthest black hole that belongs to a rare family of galaxies

Science Daily - 27/10/2020
Astronomers have identified one of the rarest known classes of gamma-ray emitting galaxies, called BL Lacertae, within the first 2 billion years of the age of the universe.

Galaxies in the infant universe were surprisingly mature

Science Daily - 27/10/2020
ALMA telescope conducts largest survey yet of distant galaxies in the early universe.

Drug resistance linked to antibiotic use and patient transfers in hospitals

Science Daily - 27/10/2020
Understanding the role of antibiotic use patterns and patient transfers in the emergence of drug-resistant microbes is essential to crafting effective prevention strategies, suggests a new study.
