One and done: Researchers urge testing eyewitness memory only once
Psychological scientists and criminologists say our system of jurisprudence needs a simple no-cost reform — switch to testing eyewitnesses for their memory of suspects only once.
It takes cellular teamwork to heal the intestine
A meticulous single-cell analytical approach to study the repair process of rotavirus-caused injury in an animal model revealed that the damaged epithelium contains a variety of cell types involved in repairing it through broad coordinated responses th…
History of insect invasions offer insight into the future
Results from a recently published study suggest that efforts to reduce biological hitchhiking on live plant imports, often referred to as ‘biosecurity,’ are working. However, more than a century of invasion by Hemiptera insects also suggests that incre…
Closer look at unexamined interactions could improve drug purification process
Research explores the fundamentals of how different molecules interact with various surfaces during the purification process.
A new dimension in magnetism and superconductivity launched
An international team of scientists has launched a new paradigm in magnetism and superconductivity, putting effects of curvature, topology, and 3D geometry into the spotlight of next-decade research.
Laboratory will illuminate formation, composition, activity of comets
Researchers have developed a laboratory to simulate comets in space-like conditions. The goal of the Comet Physics Laboratory is to understand the internal structure of comets, as well as how their constituent materials form and react. Many of the lab’…
Mapping annual wildfire probabilities across California
Researchers have uncovered new insights into the dynamics that underlie the probabilities of wildfire across the state of California.
Study links gene to cognitive resilience in the elderly
Researchers have discovered that environmental enrichment appears to activate a protein called MEF2, which controls a genetic program in the brain that promotes resilience to cognitive decline.
Autonomous robotic rover helps scientists with long-term monitoring of deep-sea carbon cycle and climate change
For the past seven years, an autonomous robotic rover, Benthic Rover II, has been continuously operational 225 kilometers off the coast of central California and 4,000 meters below the ocean’s surface. This innovative mobile laboratory has further reve…
Combining two ‘old therapies’ packs a powerful punch against pediatric brain tumors
Copper has been clinically improving the lives of people since about 1500 BCE, when an Egyptian physician first recorded its use as a treatment for inflammation. Some 35 centuries later, researchers have provided solid evidence that the first metal use…
1,000 years of glacial ice reveal ‘prosperity and peril’ in Europe
Europe’s past prosperity and failure, driven by climate changes, has been revealed using thousand-year-old pollen, spores and charcoal particles fossilized in glacial ice. This first analysis of microfossils preserved in European glaciers unveils earli…
Can eating alone be bad for your heart?
As women age, their risk of cardiovascular disease (CVD) exceeds men’s largely because of decreased levels of estrogen that regulate vascular function. As a result, much research is focused on various risk factors. A new study suggests that eating alon…
A quick, high-yield synthesis of molnupiravir, an investigational COVID antiviral pill
Molnupiravir is an investigational oral antiviral being developed for the treatment of COVID-19, and has been submitted for review by the U.S. Food and Drug Administration. Researchers now report that they have engineered enzymes to help manufacture th…
