Researchers have developed a hair-thin battery that can power robots no larger than the dot at the end of this sentence. The zinc-air battery captures oxygen from its surroundings and oxidizes miniscule amounts of zinc, a reaction that can create up to 1 volt. This energy can then power things like sensors or a tiny … Read more
Data from India’s recent Chandrayaan-3 mission supports the idea that an ocean of molten rock once covered the moon. Scientists from the mission have published their new findings in the journal Nature. On August 23 2023, a lander called Vikram successfully touched down on the lunar surface. Controllers then deployed a rover called Pragyan, which … Read more
Memories evolve throughout our lifetimes, changing as we learn and experience new things and as we recall a memory repeatedly. And then, memories degrade as we age. Previously, scientists thought that this malleability was the result of changes in the brain cells that originally encoded the memory, and they believed these cells stored just one … Read more
Researchers have made a breakthrough in the race to save the world’s bananas from a devastating disease that could wipe them out, according to a new study. The bananas we eat, called Cavendish bananas, are threatened by a plant-killing disease called fusarium wilt. This disease has already wiped out other banana varieties, and it devastated … Read more
The human body does not age at a constant rate throughout adulthood — instead, it accelerates dramatically around ages 44 and 60, a new study finds. The new research, published Aug. 14 in the journal Nature Aging,involved measuring more than 11,000 molecules in the adult body over time, and it revealed that 81% of them … Read more
Considered one of the most famous Neolithic monuments in England, this table-shaped dolmen consists of nine upright large stones that are topped by one massive capstone weighing approximately 28 tons (25 metric tons), according to English Heritage, a charity organization that oversees hundreds of historic sites in England. As early as the 13th century, people … Read more
Earth’s days once got more than two hours longer, thanks to the moon drifting thousands of miles farther away in its orbit over two periods, researchers have discovered. The extra hours of sunlight, in turn, may have led to oxygenation events that ushered in a period when life’s complexity exploded, the study researchers say. “Daylength … Read more
he world’s oceans are home to microscopic organisms invisible to the human eye. The tiny creatures, known as “prokaryotes”, comprise 30% of life in the world’s oceans. These organisms play an important role in keeping the oceans in balance. But new research by myself and colleagues shows this balance is at risk. We found prokaryotes … Read more
Researchers plan to accelerate the development of artificial general intelligence (AGI) with a worldwide network of extremely powerful computers — starting with a new supercomputer that came online in September. Artificial intelligence (AI) spans technologies including machine learning and generative AI systems like GPT-4. The latter offer predictive reasoning based on training from a large … Read more
Mars is a planet of vast contrasts — huge volcanoes, deep canyons, and craters that may or may not host running water. It will be an amazing location for future tourists to explore, once we put the first Red Planet colonies into motion. The landing sites for these future missions will likely need to be … Read more
