Scientists make quantum time flow backward in stunning physics breakthrough
Researchers have developed quantum control techniques that manipulate the direction of time's arrow within quantum systems, effectively making them appear to run in reverse. The method works by precisely managing quantum measurements to reshape how time flows through a system β and even extract usable energy from the measurement process itself. The advance opens new pathways for quantum computing, quantum batteries, and a broader class of technologies that exploit the strange mechanics of the quantum world.

Rescue mission launches to save NASA telescope that's falling back to Earth
A private spacecraft has launched on a mission to intercept and reboost a failing NASA telescope before it re-enters Earth's atmosphere. The three-armed vehicle, designed specifically for the task, represents a critical test of in-space servicing technology. The outcome could set a precedent for how agencies salvage aging orbital assets rather than letting them burn up or crash.

This spray-on powder can stop life-threatening bleeding in 1 second
Researchers at KAIST have developed a spray-on powder that halts severe bleeding in approximately one second by forming an instant gel barrier over the wound. Unlike conventional hemostatic products, it works on deep and irregular injuries while remaining stable after years of storage in extreme conditions. Designed initially for battlefield use, the technology has broad potential for emergency medicine across disaster zones, ambulances, and hospitals.

Coral loss may erase up to $3 billion in HawaiΚ»i reef recreation by 2100
HawaiΚ»i stands to lose up to $3 billion in reef-related recreation value by 2100 as climate change continues to degrade coral ecosystems, according to new research in Ecological Economics. The economic blow won't be distributed evenly β lower-income and disadvantaged communities are projected to bear a disproportionate share of the losses. The findings underscore that coral decline is not just an environmental crisis but a compounding equity issue with lasting economic consequences.

Scientists discover a protein switch that burns fat and blocks new fat cells
Researchers have identified a protein called "Mitch" that acts as a key regulator of fat storage and energy metabolism β and switching it off could be a powerful weapon against obesity. Disabling the protein in human cells triggered increased fat burning, higher energy expenditure, and suppressed the formation of new fat cells. The discovery builds on earlier findings in mice and opens a credible new avenue for developing obesity treatments that target metabolism at the cellular level.
