Tiny hologram inside a fiber lets scientists control light with incredible precision
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…
Scientists just created spacetime crystals made of knotted light
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…
Seven-week wait for some red flag patients
Some patients who have been red flagged for breast cancer assessments are waiting up to seven weeks to be seen in Northern Ireland. The target set by Northern Ireland’s devolved Department of Health – which oversees five health and social care trusts – is 14 days. BBC News NI understands that several breast cancer consultants…
Interesting Technique to Launch a Shellcode
In most attack scenarios, attackers have to perform a crucial operation: to load a shellcode in memory and execute it. This is often performed in a three-step process: Some memory must be allocated and flagged as “executable” with VirtualAlloc() (and sometimes combined with VirtualProtect()) The shellcode (often deobfuscated) is copied into this newly…
Potter wasp ‘riding a broomstick’ wows photography judges
Maddie Molloy BBC Climate & Science Bidyut Kalita This image titled “Special Delivery” was highly commended in the Behaviour: Invertebrates category. 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 pulls off Starship rocket launch in stunning comeback
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…

Scientists finally pinpoint Jupiter’s birth using “molten rock raindrops”
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…
Thylacine’s genome provides clues about why it went extinct
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…
How to write an effective prompt
Earlier today, we launched a state-of-the-art image generation and editing model, available in the Gemini app, AI Studio and Vertex AI. This update introduces significant advancements in character consistency; precise, conversational editing; and the ability to combine photos into a completely new creation. To help you get the most out of this update, here are…
