'Test-to-stay' can safely keep kids in school after COVID exposure
Children and staff who repeatedly test negative for COVID-19 after contact with someone who has the illness can safely remain in school if universal masking programs are in place, according to a new study. The finding of the "test to stay" report from the ABC Science Collaborative at Duke University provides a safe alternative to quarantining people who have been exposed to COVID-19 and enables s

Internet history: North America's first website turns 30 years old
December marks the 30-year anniversary of the first website in North America. As the World Wide Web was poised to begin its transformation of modern communications—and, well, life as we know it —a group of staff at the Department of Energy's SLAC National Accelerator Lab at Stanford University saw an opportunity to vastly improve the exchange of information within large, international physics col

Best PS5 Headsets for Intense Gaming Sessions in 2022
Sony's fifth-generation PlayStation makes the ones that came before it look practically primitive by comparison. PS5 graphics, speed, and sound offer limitless, next-gen gameplay. That is, if you can even get your mitts on one. Still, those who own one can set their watches to the cinematic-quality of games that made PlayStation a household name when it launched in the US in 1995. However, when i

The Cost of Lab-Grown Chicken Dropped by More Than Half This Year
This year saw significant rises in consumer prices across all sorts of goods, one of them being food. Amid supply chain complications, labor shortages, and plant closures, meat prices shot up, in some cases to double what they'd been a year prior. Chicken was no exception, with consumers and restaurants paying up to 125 percent more than the typical baseline price. There may soon be an unexpected

Natural antiparasitic processes hinder anisakis infection in fish
The publishing of several articles that reveal the vulnerability of farmed fish to the anisakis parasite has prompted the research group in Marine Zoology of the University of Valencia to experimentally assess the infective susceptibility of fish. The results from the ANITEST project, which just ended, show that in the improbable case that the parasite reaches farms, fish are not very susceptible

From the archive: Carlo Rovelli on how to understand the quantum world (part two)
From electrons behaving as both particles and waves to a cat in a box that's both dead and alive, the consequences of quantum physics are decidedly weird. So strange, that over a century since its conception, scientists are still arguing about the best way to understand the theory. In the second of two episodes, Ian Sample sits down with the physicist Carlo Rovelli to discuss his ideas for explain

How can the US improve COVID-19 testing?
The US is still on its heels when it comes to COVID-19 testing. Will mailing free at-home tests make a difference? An immunologist has some answers.

Depression stigma drops for first time in US
Stigma toward people with depression has dropped significantly for the first time since national data have been tracked in the United States, a new study shows. Stigma levels for other mental illnesses, however, have remained stagnant and, in some cases, have increased. The findings can help shape treatment of those with mental illness and have an impact on anti-stigma programs and policies to he

These Were the Most-Read Singularity Hub Stories of 2021
If 2020 was all about the pandemic, 2021 was supposed to be about things getting back on track. Let's just say it was a mixed bag. Along with a slower-than-hoped rollout of vaccines, the virus has had some evolutionary tricks up its sleeve too. Even so, while the world stood still last year, fixated on Covid-19, our collective gaze widened again in 2021. Perhaps it's no surprise that breakthrough

Scarcity may not drive demand for vaccines
Results from experiments asking people about COVID-19 vaccines challenge the traditional view of product scarcity driving demand. Anyone who has taken an economics class probably remembers learning about scarcity. The concept of demand outpacing supply applies to the toilet paper shortage at the onset of the COVID-19 pandemic and helps explain how a spike in home-improvement projects last year co

How the Extinction of Ice Age Mammals May Have Forced Us to Invent Civilization
Why did we take so long to invent civilization? Modern Homo sapiens first evolved roughly 250,000 to 350,000 years ago. But initial steps towards civilization—harvesting, then domestication of crop plants—began only around 10,000 years ago , with the first civilizations appearing 6,400 years ago . For 95 percent of our species' history, we didn't farm, create large settlements, or form complex po

For Mental Health, Cognitive Triangle Assumptions limits CBT
HF The cognitive triangle which CBT is based says thoughts — feelings — behavior. This has been useful against cognitive distortion with cognitive reframing. CBT's focus includes dealing with thoughts, not insisting on how they became thoughts, or where they go. This exclusion of the sections of thoughts and assumptions about feelings limits the reach of CBT. If thoughts come about something or a

The strategy of plants: It's all about balancing traits
Just like every other organism on Earth, plants' ultimate goal is to survive and reproduce. In order to achieve this, they must make trade-offs between where and how to allocate their finite set of resources. Whether they put their resources and energy into their growth, reproduction or maintenance, is all part of their so-called plant strategy. With a new framework, Ph.D. candidate Jianhong Zhou

Building an American political consensus behind environmental sustainability
When environmental protection was a barely noticed issue on the political agenda, it was able to achieve massive support from the American public.

Tree growth response to soil nutrients and neighborhood crowding varies between mycorrhizal types
Tree growth is an important part of forest dynamics, the symbiosis between trees and mycorrhizal fungi (e.g., arbuscular mycorrhizal (AM), ectomycorrhizal (EM) and dual-mycorrhizal (AEM)) can improve species ability to absorb nutrients and adapt to the local environment, which ultimately results in the difference of species response to biotic and abiotic factors.
