A new take on the abilities of hydrogen binding energy for use in single atom catalysts

A new study emphasizes the importance of pushing metal site design limits to optimize hydrogen evolution reaction in single atom catalysts. Researchers found that hydrogen binding energy calculation can serve as a good predictor of activity, and neighboring nitrogen atoms can host catalytic activity to negate poisoning effects.

Breaking the American climate silence

A study published in PLOS Climate found that Americans are more likely to discuss climate change with family and friends if they feel worried or perceive society as supportive of pro-climate behaviors. Perceived social norms emerged as the strongest predictor, followed by worry, exposure to media coverage, and perceived risk.

Does your brain know you want to move before you know it yourself?

A team of researchers, led by Jean-Paul Noel, has discovered that the brain's motor area largely coincides with the onset of intention. The study used a brain-machine interface to separate intentions from actions in a paralyzed participant, revealing a compressed temporal binding between intention and action.

Curiosity rover finds large carbon deposits on Mars

The discovery of large carbon deposits in Gale Crater suggests that ancient Mars had a CO2-rich atmosphere, which supported liquid water and potentially life. Scientists are now trying to determine how much of this CO2 was sequestered, and whether it impacted Mars' ability to stay warm.

Tying light from lasers into stable “optical knots”

Engineers at Duke University have demonstrated a method to create stable optical knots using laser beams, which could be used to transmit encoded information or measure turbulence in pockets of air. The team found that by adding more squiggles to the knot's features, they could make it stable for longer and resist degradation.

ELVIS has entered orbit: Pioneering imaging system to enhance space biology and life detection beyond earth

The Extant Life Volumetric Imaging System (ELVIS) will test a new holographic microscope on the International Space Station to analyze the adaptability and resilience of microorganisms. The system aims to reveal how life might persist on distant moons and planets, significantly enhancing our search for life outside Earth.

Nature publication explains mechanisms of mRNA-based therapeutics in study from Polish researchers

Researchers from the International Institute of Molecular and Cell Biology in Warsaw discovered a crucial role of enzyme TENT5A in extending poly(A) tails of therapeutic mRNA molecules, making them more stable and effective. Macrophages play a key role in vaccine effectiveness, capturing and neutralizing 'intruders' after administration.

Simulating protein structures involved in memory formation

Researchers developed a computational model that reproduces intricate protein structures at postsynaptic densities, crucial sites for learning and memory. The model reveals details on how these proteins organize into unique structures through liquid-liquid phase separation, enabling sustained activation of downstream signaling pathways.

“Ban-the-Box” policy did not effectively help job applicants with criminal records in one analysis

A new analysis of job applicant data from a large employer found that Ban-the-Box policies had little impact on employment rates for individuals with criminal records. Despite initial hopes that these policies would improve job prospects, the study suggests that any benefits may be reversed during subsequent candidate assessment.
