5 things to know about Kash Patel

TheHill.com 

President-elect Trump on Saturday nominated longtime ally Kash Patel to lead the FBI, tapping a figure who has pledged to reform the bureau. In doing so, Trump signaled his plan to remove FBI Director Christopher Way, whom Trump nominated to a 10-year term in 2017. Patel held numerous national security roles during the first Trump administration but...

The affordable housing shortage is reshaping parts of rural America

Flipboard.com 

A surge in home prices over the past several years is pushing homebuyers further out from city centers with big implications for America's small towns. When Suzanne D’Amico moved from Dallas an hour north to Celina, Texas, there was one grocery store, longhorn cattle down the road and no lights on …



Ultrafast dissociation of molecules studied at BESSY II

Sciencedaily.com 

An international team has tracked at BESSY II how heavy molecules -- in this case bromochloromethane -- disintegrate into smaller fragments when they absorb X-ray light. Using a newly developed analytical method, they were able to visualize the ultrafast dynamics of this process. In this process, the X-ray photons trigger a 'molecular catapult effect': light atomic groups are ejected first, similar to projectiles fired from a catapult, while the heavier atoms -- bromine and chlorine -- separate more slowly.

Revisiting vitamin D guidelines

Sciencedaily.com 

In June of 2024, the Endocrine Society, influenced by a substantial body of research conducted in recent years, published new clinical practice guidelines for the testing and supplementation of Vitamin D for the prevention of disease. These new recommendations included limiting vitamin D supplementation beyond the daily recommended intake to specific risk groups and advised against routine 25-hydroxyvitamin D [25(OH)D] testing in healthy individuals.

Temporary tattoo printed directly on the scalp offers easy, hair-friendly solution for measuring brainwaves

Sciencedaily.com 

Scientists have invented a liquid ink that doctors can print onto a patient's scalp to measure brain activity. The technology offers a promising alternative to the cumbersome process currently used for monitoring brainwaves and diagnosing neurological conditions. It also has the potential to enhance non-invasive brain-computer interface applications.

Ketone bodies: More than energy, they are powerful signaling metabolites that clean up damaged proteins

Sciencedaily.com 

Ketone bodies are not just about energy. These metabolites are powerful signaling molecules that have profound effects on the proteome and protein quality control in the brain. Scientists, working in mouse models of Alzheimer's disease and aging, and in the nematode C. elegans, reveal the ketone body -hydroxybutyrate interacts directly with misfolded proteins, altering their solubility and structure so they can be cleared from the brain through the process of autophagy. The work hints at a tantalizing... Читать дальше...

Hidden DNA in plants reveals secrets of photosynthesis

Phys.org 

Scientists have uncovered genetic variation in the unexplored DNA of the photosynthetic and energy factories of Arabidopsis plants, which plays a crucial role in the efficiency of photosynthesis in plants. These insights—published Nov. 27 in the Proceedings of the National Academy of Sciences—pave the way for more productive, climate-resilient crops that could contribute to sustainable global food security.
