Bats offer clues to treating COVID-19

Bats are often considered patient zero for many deadly viruses affecting humans, including Ebola, rabies, and, most recently, the SARS-CoV-2 strain of virus that causes coronavirus.

Study looks at life inside and outside of seafloor hydrocarbon seeps

Microbial cells are found in abundance in marine sediments beneath the ocean and make up a significant amount of the total microbial biomass on the planet. Microbes found deeper in the ocean, such as in hydrocarbon seeps, are usually believed to have slow population turnover rates and low amounts of available energy, where the further down a microbe is found, the less energy it has available.

Covid-19 cases tied to fraternity parties disrupt UC Berkeley’s reopening plans

Forty-seven cases make it ‘harder to imagine bringing our campus community back’ as planned, university saysPlans for the fall semester at the University of California, Berkeley, are in question after 47 new Covid-19 cases tied to fraternity parties emerged in the past week. University officials warn the outbreak could jeopardize the ability to move forward with in-person classes in the months...

Study identifies unique cells that may drive lung fibrosis

This is one of the first comprehensive looks at lung cells using a technology called single-cell RNA sequencing. Instead of examining a mash-up of many cells from a tissue sample, single-cell sequencing allowed researchers in this study to closely examine the individual cells that make up the lungs; to identify their function, and ultimately understand the molecular changes that may be driving the...

Ways to keep buildings cool with improved super white paints

Materials scientists have demonstrated ways to make super white paint that reflects as much as 98% of incoming heat from the sun. The advance shows practical pathways for designing paints that, if used on rooftops and other parts of a building, could significantly reduce cooling costs, beyond what standard white 'cool-roof' paints can achieve.

Safer CRISPR gene editing with fewer off-target hits

The CRISPR system is a powerful tool for the targeted editing of genomes, with significant therapeutic potential, but runs the risk of inappropriately editing ''off-target'' sites. However, a new study shows that mutating the enzyme at the heart of the CRISPR gene editing system can improve its fidelity.

Scientists urge caution, further assessment of ecological impacts above deep sea mining

A new study argues that deep-sea mining poses significant risks, not only to the area immediately surrounding mining operations but also to the water hundreds to thousands of feet above the seafloor, threatening vast midwater ecosystems. Further, the scientists suggest how these risks could be evaluated more comprehensively to enable society and managers to decide if and how deep-sea mining should...

A 'regime shift' is happening in the Arctic Ocean

Scientists find the growth of phytoplankton in the Arctic Ocean has increased 57 percent over just two decades, enhancing its ability to soak up carbon dioxide. While once linked to melting sea ice, the increase is now propelled by rising concentrations of tiny algae.

Why stakeholders in 'wind energy vs biological conservation' conflict have low mutual trust

Each year, wind turbines are responsible for the death of hundreds of thousands of airborne animals such as bats. To find a constructive way out of this ''green-green'' dilemma, companies building and running wind turbines might have to work together with environmental experts and conservationists. Yet lack of trust between them can hinder effective collaboration. Scientists show: shared values...
