Phys.org / Warm Jupiter exoplanet transiting a sun-like star discovered
An international team of astronomers reports the discovery of a new exoplanet orbiting a sunlike star as part of the Next Generation Transit Survey (NGTS). The newfound alien world, designated NGTS-39 b, is a Jupiter-sized ...
Phys.org / Bacteria turn dissolved uranium into stable compound in 130 days, study finds
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), together with Wismut GmbH and scientists from the University of Granada in Spain, have demonstrated for the first time that bacteria can convert uranium dissolved ...
Phys.org / Capturing the cosmic 'drift' before a star is born
Stars like our sun are formed from the collapse of stellar objects called prestellar cores, cold and dense concentrations of gas and dust held together by gravity. While many questions remain about the exact mechanisms of ...
Phys.org / Researchers link the mass extinction of once-dominant marine groups to intolerable heat, diminished oxygen in oceans
A new Stanford-led study offers the clearest picture yet of how some ocean life survived our planet's biggest mass extinction while most animals did not. About 252 million years ago, 96% of marine species and 70% of land ...
Phys.org / Physical laws explain why most flies evolved similar flight, with mosquitoes as outliers
A new study in PLOS Biology of 133 species of flies, mosquitoes and their relatives shows that most species fly in surprisingly similar ways. Physical and aerodynamic laws shape the evolution of their flight behavior more ...
Phys.org / Could exoplanets locked in eternal day and endless night support life?
Ever so slightly bigger than Earth, the exoplanet LHS 3844b orbits its parent star, LHS 3844, a red dwarf 48.5 light-years from our solar system. Its rotational speed mirrors its orbital speed. The result? One side of LHS ...
Phys.org / Ancient DNA challenges family assumptions in medieval Scandinavian graves
When archaeologists find adults and children buried together in medieval graves, it is often assumed that they were members of the same family. A new study from Stockholm University in Science Advances suggests otherwise.
Phys.org / Math reveals how honeybee hives balance the 'daring few, patient many' strategy
How do bees make group decisions without a leader? Math experts have determined that the best strategy is for a few to assume the risk of foraging under all conditions while the majority stay safely back and forage only when ...
Phys.org / Researchers find simple solution for extending the lifespan of LEDs made from glowing quantum dots
A new study led by MIT researchers could drive the development of more energy-efficient digital displays—such as flat-screen TVs, augmented and virtual reality headsets, smartphone screens, medical imaging devices and even ...
Phys.org / NASA space telescope maps magnetic fields of 'Lighthouse' pulsar
For the first time, scientists have used NASA's IXPE (Imaging X-ray Polarimetry Explorer) to directly measure the magnetic fields of PSR J1101−6101, a pulsar located within what is often referred to as the Lighthouse Nebula. ...
Phys.org / Giant kangaroos survived until 6,500 years ago on the New Guinea coast
Roughly 50,000 years ago, a kangaroo unlike any alive today lived in the mountain rainforests of New Guinea.
Phys.org / New model maps solar storms across 1 million miles around Earth
A team at the Applied Physics Lab is working to understand the complex science behind predicting invisible threats that can quickly cripple electric grid infrastructure on Earth.
