Experiment hopes to shine intense light on hydrogen fuel production. Nearly 150 powerful lamps that together produce light more intense than natural sunlight are the focus of the Synlight experiment in Germany that scientists hope can help create hydrogen […]

Special genes help tardigrades survive desiccation . The sturdy tardigrade, or water bear, can survive desiccation for years, pulling itself into its exoskeleton and rolling up into a ball. Unique genes create tardigrade-specific intrinsically disordered proteins that protect the water […]

Creation of synthetic yeast genome nearly completed. Scientists are close to creating synthetic yeast and could have it completed by the end of this year. The artificial genome has been completely designed and is about one-third complete, and once […]

DNA-based computer could solve problems faster. A theoretical DNA-based computer called a nondeterministic universal Turing machine could work out difficult problems faster than both conventional and quantum computers. The machine works by endlessly rearranging DNA via gene editing. New […]

Human gene expression still influenced by Neanderthal DNA. Neanderthal DNA is still influencing the expression of human genes, affecting such things as the development of illnesses, height and immune systems. “Strikingly, we find that Neanderthal sequences present in living […]

Signs of organic material spotted on Ceres . Evidence of the building blocks of life has been found on the dwarf planet Ceres. NASA’s Dawn spacecraft has detected signs of organic molecules around the Ernutet crater. Los Angeles Times. Radio […]

Thickness of Mercury’s mysterious water ice deposits measured. Water ice on Mercury is about 50 meters thick on average, but there is some flexibility in that number and exactly where that water came from remains a mystery. Researchers used […]

New species of ghost shark with buckteeth found . A new species of bucktoothed ghost shark has been described in Zootaxa. Hydrolagus erithacus is dark-colored, has a large head with big teeth and measures about 3 feet, or about 1 […]

Hydrogen transformed into metal under extremely high pressures . Hydrogen has been pressed into a metallic form using extremely high pressures. Researchers squeezed the hydrogen between two diamonds in a special apparatus. The New York Times. Chimera embryos developed in […]

Massive crack in Antarctic ice shelf grows . The giant crack in the Larsen C Ice Shelf in Antarctica is continuing to grow, threatening to soon break off a large iceberg. The crack has grown about 6.2 miles, or about […]
