Twin Brain Enzymes With Opposite Jobs: MNK1 and MNK2 Diverge at the Synapse

MNK1 and MNK2 look nearly identical and belong to the same enzyme family, yet mice missing one behave very differently from mice missing the other. The distinction narrows to synapses - the contact points between neurons - where the molecular differences between the two kinases are far more pronounced than in whole-brain samples.

Solar Weather Forecasting Gets a Weeks-Long Early Warning System

Scientists at Southwest Research Institute and NSF's National Center for Atmospheric Research have built PINNBARDS, an AI-driven tool that reconstructs subsurface solar magnetic states from surface data. The approach could extend space weather forecasting from hours to weeks, protecting GPS systems, power grids, and astronauts.

The Neurons That Tell Your Muscles to Keep Getting Stronger

Jackson Laboratory and University of Pennsylvania researchers identified a set of hypothalamus neurons expressing steroidogenic factor-1 (SF1) that activate for about an hour after exercise. Without them, mice showed zero endurance improvement after three weeks of training. Artificially activating the neurons post-exercise produced gains beyond normal. The study was published in Neuron.

One in Five TAVI Patients Can Go Home the Same Day as Their Heart Valve Procedure

A retrospective analysis of 790 TAVI procedures at James Cook University Hospital found that 160 of 279 eligible patients (57.3%) were successfully discharged the same day. Among all TAVI patients, about one in five left the same day. Thirty-day mortality (1.8% vs 0.8%) and readmission rates (4.4% vs 9.2%) did not differ significantly from those who stayed overnight.

How We Found the Missing 70% of Glucose That Disappears at High Altitude

When PET/CT scans couldn't account for 70% of improved glucose clearance in hypoxic mice, Gladstone Institutes researchers traced the missing sugar to an unexpected source: red blood cells programmed in hypoxic bone marrow to carry more glucose transporters and burn glucose faster to produce an oxygen-releasing molecule.

Red Blood Cells Are Pulling Sugar from Your Blood - and Nobody Noticed Until Now

Gladstone Institutes researchers identified red blood cells as a major hidden sink for blood glucose during low-oxygen conditions, explaining why high-altitude populations have lower diabetes rates. In mouse models, a drug called HypoxyStat that mimics tissue hypoxia completely reversed high blood sugar - working through a mechanism distinct from existing diabetes medications.

Columbia Engineers Redesign the Electrolyte to Make Anode-Free Batteries Viable

Columbia Engineering researchers developed a gel polymer electrolyte with a salt-phobic polymer network that reorganizes lithium ion solvation at the nanoscale. Anode-free pouch cells using the material retained over 80% capacity after hundreds of demanding cycles and survived aggressive drilling without thermal runaway - a failure mode that destroys conventional liquid electrolyte cells.

A Rocket Stage Burns Up and Leaves Lithium Pollution 95 Kilometers Above Earth

A lidar station in northern Germany detected a lithium plume at 94-97 km altitude in February 2025 that was 10 times the baseline concentration. Atmospheric modeling traced the source to a Falcon 9 upper stage re-entering over the Atlantic, marking the first direct detection of upper-atmospheric pollution from space debris re-entry, published in Communications Earth and Environment.

A New Immune Clock That Separates Cell Aging from Body Aging

Researchers at the Buck Institute and UC Southern California developed Tictock, a single-cell clock that measures aging within specific T-cell types rather than mixed cell populations. Applied to COVID-19 and HIV patients, it revealed that both infections accelerate aging inside naive CD8 T cells even as overall cell proportions diverge.

Prenatal Immune Stress Raises Adult Alcohol Misuse Risk - and Antioxidants May Help

Washington State University researchers found in an animal model that prenatal immune activation - simulating maternal infection during pregnancy - increased alcohol consumption and preference in adult offspring. Treating pregnant animals with vitamin C reduced but did not eliminate this increased risk, suggesting a possible preventive strategy worth investigating in human studies.
