Finds at Schöningen show wood was crucial raw material 300,000 years ago      (via sciencedaily.com)     Original source 

During archaeological excavations in the Schoningen open-cast coal mine in 1994, the discovery of the oldest, remarkably well-preserved hunting weapons known to humanity caused an international sensation. Spears and a double-pointed throwing stick were found lying between animal bones about ten meters below the surface in deposits at a former lakeshore. In the years that followed, extensive excavations have gradually yielded numerous wooden objects from a layer dating from the end of a warm interglacial period 300,000 years ago. The findings suggested a hunting ground on the lakeshore.

Researchers envision sci-fi worlds involving changes to atmospheric water cycle      (via sciencedaily.com)     Original source 

Human activity is changing the way water flows between the Earth and atmosphere in complex ways and with likely long-lasting consequences that are hard to picture. Researchers enlisted water scientists from around the globe to write story-based scenarios about the possible futures humanity is facing but perhaps can't quite comprehend yet. The results are part of a creative pathway to understand atmospheric water research with an eye towards the potential economic and policy issues that may be just beyond the horizon.

NASA's Webb probes an extreme starburst galaxy      (via sciencedaily.com)     Original source 

A team of astronomers has used NASA's James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size but hosts a frenzy of star formation activity. For comparison, M82 is sprouting new stars 10 times faster than the Milky Way galaxy.

Intelligent liquid      (via sciencedaily.com)     Original source 

Researchers have developed a programmable meta-fluid with tunable springiness, optical properties, viscosity and even the ability to transition between a Newtonian and non-Newtonian fluid. The first-of-its-kind meta-fluid uses a suspension of small, elastomer spheres -- between 50 to 500 microns -- that buckle under pressure, radically changing the characteristics of the fluid. The meta-fluid could be used in everything from hydraulic actuators to program robots, to intelligent shock absorbers that can dissipate energy depending on the intensity of the impact, to optical devices that can transition from clear to opaque.

First results from BREAD experiment demonstrate a new approach to searching for dark matter      (via sciencedaily.com)     Original source 

One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it s no minor thing currently, scientists think it makes up about 85% of all the mass in the universe.

Elastocaloric cooling: Refrigerator cools by flexing artificial muscles      (via sciencedaily.com)     Original source 

There is room for just one small bottle in the world's first refrigerator that is cooled with artificial muscles made of nitinol, a nickel-titanium alloy. But the mini-prototype is groundbreaking: it shows that elastocalorics is becoming a viable solution for practical applications. This climate-friendly cooling and heating technology is far more energy-efficient and sustainable than current methods.

AI writing, illustration emits hundreds of times less carbon than humans, study finds      (via sciencedaily.com)     Original source 

A group of scholars calculated the amount of energy used by AI tools for the tasks of writing and illustrating and compared it to the average amount of energy humans use for the same processes. Their results showed artificial intelligence results in hundreds of times less carbon emissions than humans. This does not mean, however, that AI can or should replace humans in those tasks, simply that its energy usage is less. The better approach is a partnership between humans and AI, the authors write.

Engineers 'symphonize' cleaner ammonia production      (via sciencedaily.com)     Original source 

Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the high temperatures and energy needed to manufacture it. But by improving on a well-known electrochemical reaction and orchestrating a 'symphony' of lithium, nitrogen and hydrogen atoms, engineers have developed a new ammonia production process that meets several green targets.

Ancient DNA reveals the appearance of a 6th century Chinese emperor      (via sciencedaily.com)     Original source 

What did an ancient Chinese emperor from 1,500 years ago look like? A team of researchers reconstructed the face of Chinese Emperor Wu of Northern Zhou using DNA extracted from his remains. The study suggests the emperor's death at the age of 36 might be linked to a stroke. It also sheds light on the origin and migration patterns of a nomadic empire that once ruled parts of northeastern Asia.
