The alkalinity-climate feedback. This schematic illustration shows how changes in upper-ocean density stratification and the ocean carbon cycle respond to increased atmospheric CO2 and feedback on one another to produce an amplified response on multi-century timescales. A vertical red arrow indicates an increase in that variable, while a vertical dark blue arrow indicates a decrease. Credit: Geophysical Research Letters (2023). DOI: 10.1029/2022GL101954…

Scientists have identified the exact point at which healthy brain proteins are shocked into the tangled mess that is commonly associated with Alzheimer's disease.Researchers at the University of California Santa Barbara (UCSB) are hopeful that the new laboratory technique behind the discovery can be used to directly study the 'never-before-seen' early stages of many neurodegenerative diseases.Tau proteins are abundant in the human brain. At first, these proteins look like tiny pieces of string inside neurons. As they…

Deforestation in the Amazon is nearing the point of no return, and if this ecosystem falls, it could flip from a vast carbon sink to a gushing carbon tap. Already, some climate scientists suspect the rainforest is spewing more carbon than it's absorbing.If the Amazon crosses a critical threshold of self-resilience, a new study suggests the disaster could set off a domino effect, knocking over tipping points elsewhere in the world, too, abruptly accelerating environmental crises and causing irreparable damage to the…

LG has been forced to recall four models of 86-inch TVs because the included support legs (aka “stands”) have become unstable in a number of incidents, leading to tip-overs. Thankfully, no injuries have been reported in any of the 12 reported cases, however, these TVs weigh around 100 pounds — enough to create “entrapment hazards that can result in injuries or death to children and others,” according to a recall alert from the U.S. Consumer Product Safety Commission (CPSC). An LG 86 Inch Class NANO75 UQA series LED…

Rodti MacLeary started a Mastodon instance, mas.to, in 2019. By early November 2022, it had amassed around 35,000 users.

The influx of users is propelled by each haphazard policy update Musk professes from his own Twitter account. Last week, Twitter’s billionaire owner suspended several high-profile…
