UV imaging can be used to diagnose skin conditions or detect faults in electrical systems. […]
[ad_1] By Leah Crane Astronomers may have caught a glimpse of the universe’s gravitational wave backgroundTonia Klein / NANOGrav Everything in the universe is constantly being stretched and squeezed by gravitational waves, ripples in space-time caused by the movements of massive objects. Now, astronomers may have caught the first hints of the sea of gravitational […]

[ad_1] By Leah Crane Astronomers have spotted the most distant quasar ever seenNOIRLab/NSF/AURA/J. da Silva Astronomers have discovered the most distant quasar we’ve ever seen. At about 13 billion light years away from Earth, it is showing us how the first supermassive black holes affected their galaxies. Quasars are extremely bright objects at the centres […]
[ad_1] By Christa Lesté-Lasserre Body language might change depending on whether when we tell the truth or lie Getty Images/Image Source When telling a lie, people may imitate the body language of the person they are lying to without realising they are doing it. The discovery might eventually lead to a new form of lie […]
[ad_1] By Ibrahim Sawal A houseflyPaul Farnfield / Alamy Some flies have specialised hindwings to help them take off faster, making them harder to swat. Many flies can be notoriously hard to catch. They manage to dodge incoming hazards by taking off from a standing position in a fraction of a second. They primarily use […]
[ad_1] A Duke-led team of scientists has developed a bio-compatible surgical patch that releases non-opioid painkillers directly to the site of a wound for days and then dissolves away. The polymer patch provides a controlled release of a drug that blocks the enzyme COX-2 (cyclooxygenase-2,) which drives pain and inflammation. The study appears Jan. 10, […]
[ad_1] Scientists crafting a nickel-based catalyst used in making hydrogen fuel built it one atomic layer at a time to gain full control over its chemical properties. But the finished material didn’t behave as they expected: As one version of the catalyst went about its work, the top-most layer of atoms rearranged to form a […]
