Live updates: US shoots down “high-altitude object” over Alaska

President Joe Biden gave the order to shoot the object down this morning, according to John Kirby, National Security Council coordinator for strategic communications. Biden was first briefed Thursday night “as soon as the Pentagon had enough information,” he added. Kirby explained that the object did not appear to be…

Deep-sea black carbon comes from hydrothermal vents

Hydrothermal vents have been identified as a previously undiscovered source of dissolved black carbon in the oceans, furthering the understanding of the role of oceans as a carbon sink. The ocean is one of the largest dynamic carbon sinks in the world, and is susceptible to increased carbon emissions from…

Researchers build more detailed picture of the movement of Greenland Ice Sheet

Researchers have found that the movement of glaciers in Greenland is more complex than previously thought, with deformation in regions of warmer ice containing small amounts of water accounting for motion that had often been assumed to be caused by sliding where the ice meets the bedrock beneath. The international…

CAR-T cell cancer immunotherapy gets personal: Fine-tuning stimulation doses to deficiencies in patient-specific CAR-T cells, using artificial antigen-presenting scaffolds, enables manufacturing of more potent CAR-T cell products

New adoptive T cell therapies — in which T cells, the immune system’s natural hunters patrolling the body for foreign adversaries, are retrieved from cancer-riddled patients, super-charged and amplified outside the body, and then infused back into the same patient — are changing the prospects of cancer patients. Since 2017,…

Salt cuts off the energy supply to immune regulators

Regulatory T cells ensure that immune responses happen in a controlled way. But eating too much salt weakens these cells’ energy supply, thus rendering them dysfunctional for a while. This may have implications for autoimmunity, an international team — including Dominik Müller — reports in Cell Metabolism. Eating too much…

Cockatoos know to bring along multiple tools when they fish for cashews

Goffin’s cockatoos have been added to the short list of non-human animals that use and transport toolsets. In a study publishing in the journal Current Biology on February 10, researchers show that the cockatoos carry multiple tools to their worksite when the job calls for it. This behavior has only…

Mushrooms magnify memory by boosting nerve growth

Researchers from The University of Queensland have discovered the active compound from an edible mushroom that boosts nerve growth and enhances memory. Professor Frederic Meunier from the Queensland Brain Institute said the team had identified new active compounds from the mushroom, Hericium erinaceus. Researchers have discovered lion’s mane mushrooms improve…

How protein-rich droplets form

Terahertz spectroscopy maps spontaneous formation of protein-rich droplets that may lead to neurodegenerative diseases. Using a new method “Terahertz (THz) calorimetry,” a research team from the Cluster of Excellence Ruhr Explores Solvation (RESOLV) in Bochum was successful in shedding new light on the spontaneous phase separation into a protein-rich and…

Scientists discover a rare neurological disease involving cellular recycling: New disease could provide insights into how the cell’s recycling system contributes to a healthy brain

Scientists from NIH’s National Human Genome Research Institute (NHGRI) and Undiagnosed Diseases Program (UDP) identified three children with the condition, two siblings and an unrelated child. The three children all had issues with motor coordination and speech, and one child had abnormalities in the cerebellum, the part of the brain…

How does biodiversity change globally? Detecting accurate trends may be currently unfeasible: Study finds that current monitoring data may be far too incomplete and deficient to provide a precise global picture of local biodiversity richness trends

Existing data are too biased to provide a reliable picture of the global average of local species richness trends. This is the conclusion of an international research team led by the German Centre for Integrative Biodiversity Research (iDiv) and the Martin Luther University Halle-Wittenberg (MLU). The authors recommend prioritising local…

Review strengthens evidence that repetitive head impacts can cause CTE

During the past 17 years, there has been a remarkable increase in scientific research concerning chronic traumatic encephalopathy (CTE) with researchers at the BU CTE Center at the forefront. While some sports organizations like the National Hockey League and World Rugby still claim their sports do not cause CTE, a…

The dark side of the sports betting boom | CNN Business

New York CNN  —  The sports gambling gold rush is coming at a high cost. In 2018, the Supreme Court struck down a federal ban on commercial sports betting in most of the country. Thirty-three states have made sports gambling legal in the wake of the decision. Now, on Super…
