A person who owns a car or who has a college education may be less vulnerable to COVID-19, according to an analysis of cases in Tehran, Iran, one of the early epicenters of the pandemic. While such variables do not inherently lower a person's risk, they do indicate an infrastructure of protection that persists despite how densely populated a person's district might be.
Using mathematical modeling, researchers considered a time very early in evolution when primordial species reproduced using external fertilization. In the model, bigger reproductive cells, or gametes, presented a competitive edge because they could hold more nutrients for a potential zygote. Smaller gametes, however, required fewer resources to make, which put less stress on the parent. Organisms evolved to specialize in large or small gametes, precursors to eggs and sperm.
A Clemson University physicist and collaborators from China and Denmark have created a new and potentially paradigm-shifting high-performance thermoelectric compound.
South Korea's Ulsan National Institute of Science and Technology (UNIST) has proposed a satellite-aided drought monitoring method that can adequately represent the complex drought conditions into a single integrated drought index.
Researchers at The University of South Australia's Future Industries Institute have developed technology that could eliminate water stress for millions of people, including those living in many of the planet's most vulnerable and disadvantaged communities.
A single footprint left by a cat-sized dinosaur around 100 million years ago has been discovered in China by an international team of palaeontologists.
Researchers at Duke University have developed a method that uses machine learning, satellite imagery and weather data to autonomously find hotspots of heavy air pollution, city block by city block. The technique could be a boon for finding and mitigating sources of hazardous aerosols, studying the effects of air pollution on human health, and making better informed, socially just public policy decisions.
Reliance on petroleum fuels and raging wildfires: Two separate, large-scale challenges that could be addressed by one scientific breakthrough. Researchers from two national laboratories have collaborated to develop a streamlined and efficient process for converting woody plant matter like forest overgrowth and agricultural waste - material that is currently burned either intentionally or unintentionally - into liquid biofuel.
In order to get a sense of what our future may hold, scientists have been looking to the deep past. Now, new research from the University of Massachusetts Amherst, which combines climate, ice sheet and vegetation model simulations with a suite of different climatic and geologic scenarios, opens the clearest window yet into the deep history of the Antarctic ice sheet and what our planetary future might hold.
A new study builds on previous research found educating kids about the environment was linked to greater concern in their parents. Now, they have evidence kids can have an impact outside of their homes, too.
