Mar 31st, 2025 - A team of Tel Aviv University researchers from the field of prehistoric archaeology has proposed an innovative hypothesis regarding an intriguing question: Why did ancient humans bring their young children to cave-painting sites—deep underground—through dark, meandering, hazardous passages? The researchers explain, "Next to many cave paintings, there is clear evidence of the presence of children as young as two years old. So far, most hypotheses have focused on the educational aspect—learning the community's traditions and customs. However, we believe that children also ... [Read More]

Mar 31st, 2025 - The private Fram2 mission is launching later today, sending a crew of amateurs to an unprecedented polar orbit—a frontier never before explored by astronauts. Launching rockets from the ground is one thing, but deciding on a route to follow around Earth is a different story. Earth has a set of specific orbits, and space missions travel around the planet on an orbital road of their choice. But not all orbits are created equal—some are less traveled than others. SpaceX's upcoming private mission will venture out to a polar orbit around Earth. Fram2, named in honor of the original ... [Read More]

Mar 31st, 2025 - Researchers are always developing better battery technologies, hoping to find ones that last a long time and never need to be recharged—and this month, we have yet another exciting breakthrough. South Korean scientists from the Daegu Gyeongbuk Institute of Science & Technology recently presented a prototype battery that works according to the betavoltaic principle. As the researchers explain: Amazon's Spring Sale is now until March 31, 2025! We're rounding up the best deals across all sorts of tech, including storage, laptops, hubs & more. "Nuclear batteries generate power by ... [Read More]

Mar 31st, 2025 - One of the most powerful objects in the universe is a radio quasar – a spinning black hole spraying out highly energetic particles. Come too close to one, and you'd get sucked in by its gravitational pull, or burn up from the intense heat surrounding it. But ironically, studying black holes and their jets can give researchers insight into where potentially habitable worlds might be in the universe. As an astrophysicist , I've spent two decades modeling how black holes spin, how that creates jets, and how they affect the environment of space around them. What are black holes? Black ...

Mar 30th, 2025 - As construction finishes on China's High Energy Photon Source, scientists are lining up to use it to further their research Reading Time: 2 minutes About 50km (30 miles) north of Beijing's city centre, construction is wrapping up on what is expected to be the world's brightest X-ray light source, slated to switch on later this year to power research in fields ranging from materials science to biomedicine and physics . The High Energy Photon Source (HEPS) will generate beams that are a trillion times brighter in terms of photon density than the surface of the sun , thanks to their extreme ... [Read More]

Mar 30th, 2025 - NASA's Curiosity rover has made another remarkable discovery on Mars – the largest organic compounds ever detected on the Red Planet. These molecules , discovered in a rock sample drilled in 2013, offer fresh insights into the potential of Mars to support life. The findings suggest that Mars might have hosted more advanced prebiotic chemistry than scientists had assumed. Inside Curiosity's onboard mini-lab called SAM, scientists identified three organic molecules: decane, undecane, and dodecane. These compounds contain 10, 11, and 12 carbon atoms, respectively. The researchers believe ... [Read More]

Mar 30th, 2025 - In a world chasing cleaner energy, a group of physicists may have uncovered a surprising new way to make power: by tapping into the Earth's own rotation. That's right, researchers at Princeton University have finally shown that passive electricity generation might be more than just theory. This new experiment, recently highlighted in Physical Review Research , demonstrates that a specially designed device can produce a continuous, measurable voltage—powered entirely by the planet's spin through its magnetic field. The concept sounds simple: a conductor moving through a magnetic field ... [Read More]
