MIT scientists build a tiny robot that swims using living muscle cells

MIT engineers have built a paper-thin swimming robot powered by living muscle cells that respond to flashes of light, allowing it to swim and steer through water. The breakthrough could pave the way for tiny, self-healing biological robots capable of exploring fragile environments that ordinary machines cannot safely navigate.

Scientists build a nuclear clock that could make atomic clocks obsolete

Scientists in Vienna have achieved a major breakthrough in timekeeping by creating the world’s first self-stabilizing nuclear clock, a technology that could eventually surpass even the most precise atomic clocks. Instead of relying on electrons in atoms, the clock uses the tiny nuclei of thorium atoms, which are far less sensitive to outside disturbances.

NASA is searching for hidden caves to build its first Moon base

NASA is preparing for humanity’s first Moon base with three investigations that will hunt for underground shelters, uncover hidden ice, and track dangerous conditions on the lunar surface. The findings could reveal how astronauts can survive and thrive on the Moon while laying the groundwork for future journeys to Mars.

Leucine does more than build muscle. It powers up your cells

The essential amino acid leucine can boost cellular energy production by protecting key proteins on mitochondria from being destroyed. The discovery reveals a new connection between nutrition and metabolism that could eventually lead to new approaches for metabolic disorders and cancer.

Creatine may help build muscle even without exercise, researchers find

Creatine helped middle-aged adults gain muscle and strength even without a structured workout program in a new 12-week study. When combined with exercise and a calorie-reduced diet, it produced even greater strength gains while helping participants add lean tissue and lose fat. Researchers say the results strengthen the case for creatine as a potentially useful tool for maintaining muscle with age.

Safeguards 'build a moat' around US AI firms, prevent open-source models from advancing, expert says

US President Donald Trump on Tuesday said the tech executives gathered at the White House to discuss regulating AI had signed a "morally binding" commitment to build adequate safeguards on the fast-moving technology. Speaking with FRANCE 24's Monte Francis, Harrison Rolfes, Senior Research Analyst at PitchBook, says that the push for safeguards "prevents open-source models from taking over the competition as well as new incumbents from coming in with a new frontier model", explaining that the measures "build a moat" around US AI firms.
