Back in 2012, we heard about tiny biped "biobot" robots that used actual muscle tissue to walk. Well, the descendants of those bots are now equipped with LEDs, which allow them to be remotely steered in a practical fashion.

What was once thought to be just one star is actually two. What's more, the two stars are so close that they've broken a record for being the tightest ultracool binary system ever observed, revolving around each other in less than an Earth day.

Ordinarily, pacemakers correct irregular heartbeats by delivering an electric shock to the entire heart – which can be painful. An experimental new one takes a different approach, and it does so by encompassing the heart with light-emitting "petals."

Scientists studying the brains of so-called “SuperAgers” have discovered a set of significantly enlarged neurons associated with memory that also appeared more resistant to characteristics of Alzheimer’s disease.

In a new study, chemists claim to have found an Achilles’ heel to the ultra-stable molecules of toxic PFAS "forever chemicals." Using a relatively simple chemical reaction, the team could “decapitate” some kinds of PFAS into benign end products.

A new study on fruit flies may help explain why siestas came to be such an important habit in many cultures, revealing a type of brain thermometer that kicks sleep-promoting cells into action as the mercury starts to climb.

Nobody wants to suffer physical pain if they don't have to, yet they also don't want to risk developing an addiction to pain-killing opioids. That's where a new drug-free implant comes in, as it reduces pain by cooling nerves.

Last year, scientists at Northwestern University announced a transient pacemaker that dissolves when no longer needed. They've now improved the device, and incorporated it into a linked suite of wearable sensors.

Researchers at Northwestern University in Illinois have demonstrated the world's smallest remote-controlled walking robot. These tiny machines can bend, twist, crawl, walk, turn and jump without hydraulics or electricity, using shape-memory alloys.

Scientists studying the mechanisms behind deafness have pinpointed a single gene they described as a type of master switch for cell differentiation, opening up exciting new possibilities around restoration of hearing.

Researchers have found sleeping in a moderately lit room can potentially harm a person’s cardiometabolic health. The study saw one night of sleep in a room with moderate light increased nighttime heart rates and spiked insulin resistance in the morning.

Researchers have uncovered a mechanism they say contributes to the age-related accumulation of iron in the brain. The study bolsters the hypothesis that reducing brain iron levels could combat neurodegenerative diseases such as Alzheimer’s.
