The science community should withdraw from involvement in international tests such as PISA because they have forced schools to adopt "narrow" curricula and pedagogies, a study says.
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.
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.
Move over, murder hornets. There's a new bee killer in town.
New research from the University of Virginia School of Medicine reveals how plants create the load-bearing structures that let them grow—much like how building crews frame a house.
For the first time in nearly 50 years, California condors have been spotted at Sequoia National Park, wildlife officials announced.
A new study by the Marine Laboratory at the University of Guam may help researchers predict coral bleaching months earlier than current tools, and, for the first time, may help predict invasion events of coral-eating crown-of-thorns starfish. The study was published on May 8 in Scientific Reports.
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...

Biologists have traced the stability of plant mitochondrial genomes to a particular gene - MSH1 - that plants have but animals don't. Their experiments could lend insight into why animal mitochondrial genomes tend to mutate.
Warmer than average sea surface temperatures in the tropical North Atlantic Ocean so far in 2020 have set the stage for an active hurricane season and elevated the risk of fires in the southern Amazon, according to scientists at NASA and the University of California, Irvine.
The discovery unveils the molecular machinery that plants use to weave cellulose chains into cable-like structures called 'microfibrils.'
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...
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.
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.
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...
Researchers are developing an A.I. platform that provides users with access to the information and insights hidden inside federal court records, regardless of their data and analytic skills.
Scientists have digitally 'dissected', for the first time, the most primitive jawed fish fossils with teeth found near Prague more than 100 years ago. The results show that their teeth have surprisingly modern features.
Researchers have found a significant increase in patients experiencing stress cardiomyopathy, also known as broken heart syndrome, during the COVID-19 pandemic.
Researchers propose a decentralized, global wildlife biosurveillance system to identify -- before the next pandemic emerges -- animal viruses that have the potential to cause human disease.
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.
A new study of 2,500 Dutch children is the first to explore the relationship between brain volume and different doses of radiofrequency electromagnetic fields.
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...
Women who deliver their first child by cesarean section (C-section) are less likely to conceive a second child than those who deliver vaginally, despite being just as likely to plan a subsequent pregnancy, according to researchers. The team followed more than 2,000 women for three years after they delivered their first child.
Researchers find that the benefits of inhalers for asthma sufferers outweigh the risks of contracting coronavirus, following concerns raised after WHO warned that steroids could reduce immunity.
