As we learn more about how the coronavirus spreads between people, there’s more evidence to suggest that most infections are transmitted by a select few individuals we call “superspreaders.” Here’s what a superspreader is, the role these people play in transmitting the virus, and what we’re trying to do about it. What is a superspreader? The word is a generic term for...
The COVID-19 pandemic has underscored the critical need for robust scientific evidence to support policy decisions, such as around the effectiveness of various social distancing measures and the safety of drug therapies. Yet this need arises at a time of growing misinformation and poorly vetted facts repeated by influential sources. To address this gap, a group of scientists led by Kai Ruggeri, a...
Engineers from Duke University have developed a comprehensive new model of deep-seated landslides and demonstrated that it can accurately recreate the dynamics of historic and current landslides that occur under various conditions.
Northwestern University synthetic biologists have developed a new rapid-prototyping system to accelerate the design of biological systems, reducing the time to produce sustainable biomanufacturing products from months to weeks.
A recently published nationwide study by two University of South Florida professors indicates that blacks are five times more likely and Latinos four times more likely to fear police brutality than whites.
While humans have three color cones in the retina sensitive to red, green and blue light, birds have a fourth color cone that can detect ultraviolet light. A research team trained wild hummingbirds to perform a series of experiments that revealed that the tiny birds also see combination colors like ultraviolet+green and ultraviolet+red.
Engineers have developed a comprehensive model of deep-seated landslides and demonstrated that it can accurately recreate the dynamics of historic and current landslides occurring under varying conditions. The model points to the temperature of a thin layer of clay at the base of the landslide as critical to the potential for sudden cataclysmic failure. The approach is currently monitoring a...
New research by University of Delaware doctoral student Zhangxian Ouyang and oceanographer Wei-Jun Cai, and an international team of researchers, demonstrates that rapid warming and sea-ice loss have induced major changes in the western Arctic Ocean.
NASA's Curiosity Mars rover occasionally stops to stargaze. Recently, it captured a shot of Earth and Venus in the Red Planet's night sky.
Imagine Earth completely covered in ice. While it's hard to picture all of today's oceans and land masses obscured with glaciers, such an ice-covered version of the planet was not so far-fetched millions of years ago.
In one of the largest educational field experiments ever conducted, researchers found that promising interventions to help students complete online courses were not effective on a massive scale -- suggesting that targeted solutions are needed to help students in different circumstances or locations.
A new cell-free platform rapidly identifies optimal enzyme combinations for sustainable fuels and materials.
Ice melts in the Arctic Ocean were thought to be drawing large amounts of carbon dioxide out of the atmosphere, acting as a carbon sink and helping to mitigate greenhouse gases. But new research shows that may not be the case in all areas, particularly in the Canada Basin, where the carbon sink is shrinking, inhibiting the ocean's ability to absorb carbon dioxide from the atmosphere into the deep...
Radiation found by a group of scientists known as the "Ring of Five" has been shown to have come from a Russian nuclear...
When we cut our fingers, blood rushes out of the wound to close it. However, the vegetable we just wanted to slice and dice, would have reacted completely differently to this injury. Scientists at the Institute of Science and Technology Austria (IST Austria) investigated how plant cells heal wounds. In their results, published in PNAS on June 15, the researchers discovered that the hormone auxin...
In one of the largest educational field experiments ever conducted, a team co-led by a Cornell researcher found that promising interventions to help students complete online courses were not effective on a massive scale—suggesting that targeted solutions are needed to help students in different circumstances or locations.
Water and its interactions with other substances are essential to human life. However, understanding the structure of liquid water and its hydrogen-bonding networks has been a challenge.
To find food, dazzle mates, escape predators and navigate diverse terrain, birds rely on their excellent color vision.
Picture 500 million cars stacked in rows. That's how much carbon—about 1,000 petagrams, or one billion metric tons—is locked away in Arctic permafrost.
Throughout history, portraits featuring the human profile have evolved to reflect changing cultural norms. A new study led by Helena Miton, a Santa Fe Institute Omidyar Fellow, and co-authored by Dan Sperber of Central European University and Mikołaj Hernik, of UiT the Artic University of Norway, shows that human cognition plays a critical role in the evolution of human portraiture.
The COVID-19 pandemic threatens the survival of organizations nationwide that provide critical outdoor environmental and science education to K-12 students, with an alarming 63% of such groups uncertain about their ability to ever reopen their doors, according to a study released this week by the Lawrence Hall of Science at the University of California, Berkeley.
Many of us have seen informational posters at parks or aquariums specifying how long plastics bags, bottles, and other products last in the environment. They're a good reminder to not litter, but where does the information on the lifetime expectancy of plastic goods come from, and how reliable is it?
Scientists at the National Institute of Standards and Technology (NIST) and the Massachusetts Institute of Technology (MIT) have demonstrated a potentially new way to make switches inside a computer's processing chips, enabling them to use less energy and radiate less heat.
An animation of four days of imagery from NASA's Terra satellite showed the progression and landfall of Tropical Storm Nuri.
