Shuffling quantum objects is much stranger than shuffling classical ones Andriy Onufriyenko/Getty Images Quantum computers can produce randomness much more easily than previously thought, a surprising discovery that shows we still have much to learn about how the strange realm of quantum physics intersects with computation. Randomness is a key component of many computational tasks…
Proof That Adult Brains Make New Neurons Settles Scientific Controversy Adult brains grow new neurons, and scientists have finally pinpointed where they come from By Nora Bradford edited by Allison Parshall Neural precursor cells (green) are have been difficult to identify in human brians.

People with type 1 diabetes can’t produce enough insulin to regulate their blood sugar Halfpoint Images/Getty Images Researchers have 3D printed devices made of insulin-producing cells. These devices could enable a long-term treatment for type 1 diabetes that would let people produce their own insulin – without requiring invasive surgery. Because people with type 1…
4,800-Year-Old Teeth Yield First Human Genome from Ancient Egypt Forty years after the first effort to extract mummy DNA, researchers have finally generated a full genome sequence from an ancient Egyptian, who lived when the earliest pyramids were built By Ewen Callaway & Nature magazine The Ancient Egyptian Old Kingdom (2686–2125 B.C.) produced many lasting…
Evidence is mounting that a microbe called Methanobrevibacter smithii is involved in colorectal cancer KATERYNA KON/SCIENCE PHOTO LIBRARY/Alamy Mysterious ancient microorganisms that are neither bacteria nor viruses seem to play a role in colorectal cancer. This supports the idea that such microbes, which were thought to be harmless, could actually be involved in human disease….
For only the third time in history, astronomers have detected a new interstellar visitor — an object from another star — blitzing into our solar system. First named A11pl3Z and now designated as 3I/ATLAS , the comet was spotted by a survey telescope in Chile on July 1 and confirmed by the International Astronomical Union’s…

The Matarrubilla stone at Valencina in Spain was transported more than 5300 years ago L. García Sanjuán A 2-tonne megalith in southern Spain was transported to its present location by a hitherto-unknown group of ancient seafarers over 5300 years ago. The Matarrubilla stone is a solid slab of gypsum about 1.7 metres long by 1.2…
Two studies fill in gaps about the cosmos’s ordinary matter. One maps it all, even the “missing matter.” The other details one of its hiding spots.
