8+ mon, 1+ day ago   (720+ words) Blood vessels, neurons, and tree branches often form junctions that look irregular, yet they follow a shared geometric rule. Using three-dimensional scans from six kinds of organisms, researchers in New York linked those shapes to surface costs. Branching tubes and…...

1+ week, 17+ hour ago   (690+ words) In 1959, engineers at a U.S. Army laboratory built a device that amplified and routed signals using nothing but jets of air. More than six decades later, that half-forgotten technology is driving a quiet revolution in robotics. A team at King’s College…...

6+ mon, 2+ week ago   (822+ words) Scientists have found traces of a tough material that once formed the outer shells of ancient sea creatures called trilobites, preserved inside fossils that are more than 500 million years old. The discovery shows that parts of living organisms can last…...

7+ mon, 4+ day ago   (808+ words) Large, accessible coal deposits have emerged as a decisive prerequisite for extraterrestrial technological civilizations on exoplanets capable of becoming detectable beyond their home worlds. That finding reframes cosmic silence as a geological outcome, not simply a question of biology or…...

8+ mon, 3+ week ago   (849+ words) Nighttime is when cameras struggle, but a sensing method called HADAR, short for heat assisted detection and ranging, lets machines see detail in darkness. In tests it recovered texture, distance, and material information at night with accuracy similar to stereo…...

9+ mon, 2+ week ago   (902+ words) A new artificial intelligence system takes on one of science’s toughest questions: did this chemistry originate from life or not? Built by researchers at Georgia Tech and NASA’s Goddard Space Flight Center, the technology studies meteorites and Earth soils for…...

2+ mon, 4+ day ago   (763+ words) The search for life beyond Earth has always been full of surprises. Strange radio signals have sparked excitement. Odd gases on distant worlds have raised questions. Even ordinary objects have been mistaken for UFOs. Time and again, scientists have had…...

11+ mon, 4+ day ago   (832+ words) A new study looked at how word meanings shift and asked who actually changes their language when that happens. It found that adults of all ages tend to move together, with only a small delay between younger and older speakers....

1+ mon, 6+ day ago   (965+ words) Tool use gives some animals access to foods that teeth, fingers, or claws cannot easily open. Yet using a tool is only part of the challenge because the animal must also choose an object with the right qualities for the…...
