Proton exchange membrane fuel cells (PEMFCs), often referred to as “hydrogen power banks,” are clean energy devices that generate electricity from hydrogen and oxygen with only water as a byproduct. Characterized by high efficiency, rapid start-up, and zero emissions, they hold great promise in transportation, portable electronics, and stationary power generation. Unfortunately, PEMFCs currently rely…

Precise control of light focus is essential for applications ranging from microscopy and laser surgery to quantum optics and telecommunications. However, existing solutions often rely on large, complex external components that limit integration and speed. In a new study published in Light: Science & Applications, researchers led by Professor Markus A. Schmidt from the Leibniz…

An internationally joint research group between Singapore and Japan has unveiled a blueprint for arranging exotic, knot-like patterns of light into repeatable crystals that extend across both space and time. The work lays out how to build and control “hopfion” lattices using structured beams at two different colors, pointing to future systems for dense, robust…

At first glance, the potter wasp appears to be riding a broomstick. But this industrious insect isn’t flying back to stir its witch’s cauldron, or playing Quidditch. It’s carrying a caterpillar – prey to…

SpaceX has pulled off a successful test flight of its newest generation rocket Starship, reversing a trend of disappointing failures. The world’s largest and most powerful rocket blasted off from Texas just after 18:30 local time (23:30 BST) for a nail-biting 60-minute flight. Parts of the engine appeared to explode at one stage, and flaps…

Four and a half billion years ago Jupiter rapidly grew to its massive size. Its powerful gravitational pull disrupted the orbits of small rocky and icy bodies similar to modern asteroids and comets, called planetesimals. This caused them to smash into each other at such high speeds that the rocks and dust they contained melted…

Thylacines were once found throughout Australia and New Guinea Robert Nickelsberg/Getty Images The loss of crucial genes over millions of years before the arrival of humans in Australia may have left thylacines more vulnerable to extinction. The thylacine, or Tasmanian tiger (Thylacinus cynocephalus) was the last survivor of a family of marsupials known as Thylacinidae…
