Another mutated version of the coronavirus has popped up in New York City, and experts reacted to the the news with a mixture of caution and concern.

Monarch butterflies down 26% in Mexico wintering grounds

The number of monarch butterflies that showed up at their winter resting grounds in central Mexico decreased by about 26% this year, and four times as many trees were lost to illegal logging, drought and other causes, making 2020 a bad year for the butterflies.

Facebook signs pay deals with 3 Australian news publishers

Facebook announced on Friday preliminary agreements with three Australian publishers, a day after the Parliament passed a law that would make the digital giants pay for news.

When devastation strikes the oceans, sharks can hold the key to recovery

A world without sharks is a world less resilient to extreme climate events, scientists say.

Risk communication experts analyze visual responses to tornado warning graphics

According to the National Weather Service, the average lead time for a tornado warning is now up to 13 minutes nationally, a significant improvement from the 1980s when the average was just five minutes.

First complete coronavirus model shows cooperation

The COVID-19 virus holds some mysteries. Scientists remain in the dark on aspects of how it fuses and enters the host cell; how it assembles itself; and how it buds off the host cell.

Social dilemma follows 2018 eruption of Kilauea volcano

The unprecedented cost of the 2018 Kilauea eruption in Hawai'i reflects the intersection of distinct physical and social phenomena: infrequent, highly destructive eruptions, and atypically high population growth, according to a new study published in Nature Communications and led by University of Hawai'i at Mānoa researchers.

Scientists use Doppler to peer inside cells

Doppler radar improves lives by peeking inside air masses to predict the weather. A Purdue University team is using similar technology to look inside living cells, introducing a method to detect pathogens and treat infections in ways that scientists never have before.

Landmark study details sequencing of 64 full human genomes to better capture genetic diversity

Researchers at the University of Maryland School of Medicine (UMSOM) co-authored a study, published today in the journal Science, that details the sequencing of 64 full human genomes. This reference data includes individuals from around the world and better captures the genetic diversity of the human species. Among other applications, the work will enable population-specific studies on genetic predispositions to human diseases as well as the discovery of more complex forms of genetic variation.

Nuclear physicists on the hunt for squeezed protons

While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights into the particles that build our universe.

Identifying patient-specific differences to treat HCM with precision medicine

Hypertrophic cardiomyopathy (HCM) is a cardiovascular disease characterized by thickening of the left ventricle, otherwise known as the main squeezing chamber of the heart. HCM is best known for causing sudden death in athletes but can occur in persons of any age, often without symptoms. While frequently discussed in the context of genetics, most patients with HCM do not have a known genetic variant. Investigators from Brigham and Women's Hospital uncovered a means to study the complexity of this disease beyond the identification of individual genes. This new approach offers a path toward treating HCM using individualized medicine. In a recent study, investigators analyzed the role protein-protein interactions (PPIs) play in differentiating individual cases of HCM. Their results are published in Nature Communications.

Urban Americans more likely to follow covid-19 prevention behaviors than rural Americans

Timothy Callaghan, Ph.D., and Alva Ferdinand, DrPH, JD, from the Southwest Rural Health Research Center at Texas A&M University School of Public Health, joined colleagues in the first national study of how often people in urban and rural areas in the United States follow COVID-19 guidelines. These include public health best practices like wearing masks in public, sanitizing homes and work areas, maintaining physical distancing, working from home and avoiding dining in restaurants or bars.

Imaging space debris in high resolution

Litter is not only a problem on Earth. According to NASA, there are currently millions of pieces of space junk in the range of altitudes from 200 to 2,000 kilometers above the Earth's surface, which is known as low Earth orbit (LEO). Most of the junk is comprised of objects created by humans, like pieces of old spacecraft or defunct satellites. This space debris can reach speeds of up to 18,000 miles per hour, posing a major danger to the 2,612 satellites that currently operate at LEO. Without effective tools for tracking space debris, parts of LEO may even become too hazardous for satellites.

Study highlights need for improving methane emission database

A University of Oklahoma-led study published in 2020 revealed that both area and plant growth of paddy rice is significantly related to the spatial-temporal dynamics of atmospheric methane concentration in monsoon Asia, where 87% of the world's paddy rice fields are situated. Now, the same international research team has released a follow-up discussion paper in the journal Nature Communications. In this paper, the team identifies the limits and insufficiency of the major greenhouse emission database (EDGAR) in estimating paddy rice methane emissions.

New sustainable building simulation method points to the future of design

A team from Cornell University's Environmental Systems Lab, led by recent graduate Allison Bernett, has put forth a new framework for injecting as much information as possible into the pre-design and early design phases of a project, potentially saving architects and design teams time and money down the road.

Study uncovers flaws in process for maintaining state voter rolls

States regularly use administrative records, such as motor-vehicle data, in determining whether people have moved to prune their voter rolls. A Yale-led study of this process in Wisconsin shows that a significant percentage of registered voters are incorrectly identified as having changed addresses, potentially endangering their right to vote.

Embed germ defence behaviours at home to reduce virus spread now and in the future

Whilst the nation has taken to washing its hands regularly since the start of the pandemic, other individual behaviours, such as cleaning and disinfecting surfaces or social distancing within the home, have proved harder to stick, say the researchers behind the behaviour change website 'Germ Defence'.

Survey reveals hidden health and wellness benefits of COVID-19 pandemic

A study by physiology researchers at The University of Texas at El Paso found that El Paso's stay-at-home ordinance due to the COVID-19 pandemic had positive effects on the health and well-being of the region's residents.

Huge gaps in UK regulation exist following transition from EU, new academic report finds

The UK is still not in a position to assume responsibility for regulation in several critical policy areas including trade, crime and the environment, a new academic report—UK regulation after Brexit—has found.

Improving water quality could help conserve insectivorous birds

A new study shows that a widespread decline in abundance of emergent insects—whose immature stages develop in lakes and streams while the adults live on land—can help to explain the alarming decline in abundance and diversity of aerial insectivorous birds (i.e. preying on flying insects) across the USA. In turn, the decline in emergent insects appears to be driven by human disturbance and pollution of water bodies, especially in streams. This study, published in Frontiers in Ecology and Evolution, is one of the first to find evidence for a causal link between the decline of insectivorous birds, the decline of emergent aquatic insects, and poor water quality.
