Today's Science Highlights: From Brain Aging to Mars Sample Return

Brain Changes Around 50 Linked to Alzheimer's Risk

Scientists have discovered that the brain's memory center undergoes a significant immune cell transformation beginning around age 50, with protective cells being replaced by inflammatory ones—a change that may help explain the link between normal aging and Alzheimer's disease.

Earth's Molten Core Reverses Direction

Satellite measurements have revealed a surprising reversal in the movement of Earth's liquid iron core beneath the Pacific, signaling a significant change in the deep-Earth processes that sustain our planet's magnetic field.

mRNA Flu Vaccine Shows Promise

Moderna's mFlusiva mRNA flu vaccine demonstrates stronger and more durable immune responses compared to traditional flu shots, and shows greater efficacy at preventing infection, according to recent data.

China Plans Only Mars Sample Receiving Lab

China has announced plans to build the only Mars sample receiving laboratory on Earth, positioning itself to handle Martian material as NASA's own sample return mission remains in flux due to budget constraints.

NASA Repurposes Gateway Elements for Moon Base

NASA and Northrop Grumman are repurposing elements originally designed for the lunar Gateway outpost to support upcoming Moon base demonstration missions, marking a strategic shift in how hardware developed for orbital infrastructure can be utilized for surface operations.

Court Blocks Trump Administration's Wind Project Suspension, Rules It Violates Law

A federal court has issued a ruling against the Trump administration's hold on wind energy projects, determining that the blanket suspension clearly violates established law. The decision represents a legal checkpoint on executive actions targeting the wind power sector. The court's ruling focused on whether the

UCLA Researchers Demonstrate Wave-Like Heat Conduction at Room Temperature

Heat conduction is typically a diffuse process—thermal energy spreads outward in all directions from a hot source, much like ink spreading through water. Now, researchers at UCLA have demonstrated a fundamentally different behavior: directing heat through a crystal in concentrated, beam-like rays, at room temperature. The team showed that

Europe Advances IRIS² Satellite Network Plans

The European Union has finalized plans for IRIS² (Infrastructure for Resilience, Interconnection & Security by Satellite), its ambitious satellite broadband network intended to serve as a European alternative to commercial megaconstellations. The program aims to provide secure, high-speed satellite communications across the EU and potentially beyond. By developing its own
