SpaceSep 21, 2023The commanding general of the U.S. Space Force says the service is revising a commercial space strategy to offer more specific guidance on what commercial capabilities are needed, particularly in space domain awareness.
SpaceSep 21, 2023Scientists in China have synthesized spider silk from genetically modified silkworms, producing fibers six times tougher than the Kevlar used in bulletproof vests.
BiologySep 21, 2023Ahead of World Rivers Day (24 September), new research by the University of Oxford reveals that sewage discharge into rivers has a greater impact on water quality, and the animals and plants that live in rivers, than surrounding land use. The findings have been published in the journals Global Change Biology and Ecological Solutions and Evidence.
BiologySep 21, 2023Researchers have coaxed human stem cells to form early-stage human kidneys in pigs—the first time a human organ has been produced in another animal. The advance, stem cell researchers say, could bring pig-grown human organs closer to reality, offering a new solution for the many people on waitlists for transplants.
BiologySep 21, 2023Vaccines rile up the immune system against pathogen invaders. But in autoimmune diseases, the immune system becomes the enemy. Scientists have now figured out a way to tamp down this self-destructive response in mice by attaching sugars to molecules that provoke immune cells. This “inverse vaccine,” reported this month in Nature Biomedical Engineering, could potentially lead to new ways to combat autoimmune diseases such as multiple sclerosis (MS) and lupus.
BiologySep 21, 2023Spider silk is stretchy, strong, and tough. But genetically engineering a more cooperative organism to produce it has proved elusive. Now, researchers have used gene editing to make silkworms that can spin spider fibers tougher than the Kevlar used in bulletproof vests.
BiologySep 21, 2023Government policies to fight climate change are discouraging oil companies from investing heavily in new production even as they turn in record profits - a dynamic that could spell tight supply and high prices as clean energy alternatives seek to fill the void.
EnergySep 21, 2023Oil prices fell in early Asian trade on Thursday, after posting the largest fall in a month in the previous session, as U.S. interest rate hike expectations offset the impact of drawdowns in U.S. crude stockpiles.
