Hybrid learning, where children alternate days learning at home and days in school, offers a significant reduction in the spread of COVID-19, a new study shows. However, total closure in favor of remote learning offers little additional advantage over the hybrid option. The study helps quantify the effectiveness of one of the most commonly-debated mitigation measures taken across the country as c

What is the future of Black Twitter under Elon Musk?
 
Black Twitter, a subset of the platform distinguished by its hashtag, has been supporting and driving causes in the U.S.—including the Black Lives Matter movement—for more than a decade. But the future of the online community is in doubt now that Elon Musk has bought Twitter, says Meredith Clark, an associate professor and founding director of the Center for Communication, Media Innovation and Soc

New findings about the bacteria that causes listeriosis
 
Listeriosis is a zoonotic disease of food origin that can cause, both in the human species and in animals, symptoms of gastroenteritis, meningitis, bacteremia and miscarriages. The pathogen that causes this infection is the Listeria bacteria.

Team discovers new way astrocytes and neurons communicate
 
Researchers have discovered a previously unknown function performed by cells called astrocytes, which comprise nearly half of all cells in the brain. The discovery in mice of a new function for astrocytes opens a new direction for neuroscience research that might one day lead to treatments for disorders such as epilepsy, Alzheimer's, and traumatic brain injury, scientists say. It comes down to ho

Why Indigenous forest guardianship is crucial to climate action | Nonette Royo
 
Indigenous communities have looked after their ancestral forests for millennia, cultivating immense amounts of knowledge on how to protect, nourish and heal these vital environments. Today, 470 million Indigenous people care for and manage 80 percent of the world's biodiversity — yet their legal rights to these lands are inexplicit and subject to exploitation by illegal loggers, miners and compan

In India, Digital Snooping on Sanitation Workers
 
Many sanitation workers in India must wear GPS trackers, and some say taking off the device incurs a fine of half a day's salary, around $4. Workers also have to take the devices home, and worry about privacy leaks and the inability to turn off the trackers and cameras — even when they are in the bathroom.

High-performance cavity-enhanced quantum memory with warm atomic cell
 
Nature Communications, Published online: 02 May 2022; doi:10.1038/s41467-022-30077-1 Quantum memories usually suffer from a trade-off between efficiency and excess noise. Here, by exploiting the time-reversal approach for improving modes matching, the authors show a warm-atomic-cell-based cavity-enhanced memory with 67% efficiency and noise level close to quantum noise limit.
