Imagine being able to look inside a single cancer cell and see how it communicates with its neighbors. Scientists are celebrating a new technique that lets them study the fatty contents of cancer cells, one by one.
Two independent research teams have successfully regenerated mouse brain circuits in mice using neurons grown from rat stem cells. Both studies, published April 25 in the journal Cell, offer valuable insights into how brain tissue forms and present new opportunities for restoring lost brain function due to disease and aging.
Prof. Zhang Ying's group from the Institute of Physics of the Chinese Academy of Sciences (CAS), in collaboration with domestic universities and the Los Alamos National Laboratory in the United States, has experimentally observed current-driven antiskyrmion sliding.
On Earth Day, the National Weather Service and the Centers for Disease Control and Prevention teamed up to announce a new heat risk system to better communicate the severity of hot weather. The color-coded system added magenta, a fifth-tier of heat severity, beyond red, to communicate extreme heat “rare and/or long-duration extreme heat with little to no overnight relief,” according to the Associated Press. The new risk system also projects out extreme weather in a seven-day forecast, allowing...
Carbon dots (CDs) are an intriguing class of nanomaterials that have attracted a great deal of attention in recent years. These carbon-based materials possess excellent fluorescence properties, making them highly appealing for a wide range of applications.
How do you feel about eating blue wheat?
A new study has revealed for the first time the vital role carbon dioxide (CO2) plays in determining the lifespan of airborne viruses—namely SARS-CoV-2, the virus that causes COVID-19. It clearly showed keeping CO2 levels in check helps to reduce virus survival, and therefore the risk of infection.
A team led by atmospheric scientists at the U.S. Department of Energy's Brookhaven National Laboratory has demonstrated the first-ever remote observations of the fine-scale structure at the base of clouds. The results, just published in npj Climate and Atmospheric Science, show that the air-cloud interface is not a perfect boundary but rather is a transition zone where aerosol particles suspended in Earth's atmosphere give rise to the droplets that ultimately form clouds.
Scientists at KAIST have come up with a new fast-charging battery made with sodium.
In a new study published in Nature Chemistry, UNC-Chapel Hill researcher Ronit Freeman and her colleagues describe the steps they took to manipulate DNA and proteins—essential building blocks of life—to create cells that look and act like cells from the body. This accomplishment, a first in the field, has implications for efforts in regenerative medicine, drug delivery systems, and diagnostic tools.
