The poison frog that fooled scientists for decades
Researchers discovered that a poison frog species described decades ago was based on a mix-up involving the wrong museum specimen. The frog tied to the official species name turned out to be brown, not the colorful animal shown in the original photo. After tracing old records and images, scientists corrected the error and reclassified the frog as part of an already-known species. The case underscores how vital museum collections are—and how even small mistakes can ripple through science for years.View the full article

SETI watched a pulsar flicker for months and found space keeps shifting
A distant pulsar’s radio signal flickers as it passes through space, much like stars twinkle in Earth’s atmosphere. By monitoring this effect for 10 months, researchers watched the pattern slowly evolve as gas, Earth, and the pulsar all moved. Those changes create minuscule delays in the signal, but measuring them helps keep pulsars incredibly precise. The findings also aid SETI scientists in spotting signals that truly come from beyond Earth.View the full article

Scientists create robots smaller than a grain of salt that can think
Researchers have created microscopic robots so small they’re barely visible, yet smart enough to sense, decide, and move completely on their own. Powered by light and equipped with tiny computers, the robots swim by manipulating electric fields rather than using moving parts. They can detect temperature changes, follow programmed paths, and even work together in groups. The breakthrough marks the first truly autonomous robots at this microscopic scale.View the full article

Scientists discover “migrions,” a viral shortcut that supercharges infection
Scientists have uncovered a surprising viral shortcut that turns moving cells into delivery vehicles for infection. Instead of spreading one virus at a time, infected cells bundle viral material into large structures called Migrions and pass them directly to new cells. This collective delivery jump-starts viral replication and boosts disease severity. The finding reveals a migration-based route of viral spread that defies classic models of infection.View the full article

Think you make 200 food choices a day? Think again
The idea that we make over 200 unconscious food choices a day has been repeated for years, but new research shows the number is more illusion than insight. The famous figure comes from a counting method that unintentionally exaggerates how many decisions people really make. Researchers warn that framing eating as mostly “mindless” can undermine confidence and self-control. A more realistic view focuses on meaningful choices—and practical strategies that make healthy decisions easier.View the full article
