Dialog / Dark energy flips its sign, but the Hubble tension refuses to budge
For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the Supernova Cosmology Project, led by Saul Perlmutter, and the High-Z Supernova Search Team, led by ...
Phys.org / Visible light triggers three-step cascade to make 3D drug-like molecules
A team led by chemist Frank Glorius, a professor at the Institute of Organic Chemistry at the University of Münster, has developed a new light-driven reaction sequence. In this triple catalysis, one reaction step triggers ...
Phys.org / China takes a page from SpaceX and recaptures the first stage of a rocket to reuse it
China successfully recaptured the first stage of a rocket after a launch on Friday in a breakthrough for the country's space program, state media said.
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 / 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 / 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 / Does multitasking ability really differ by sex? Not in the way you'd think
Research simulates real-life multitasking performance to assess potential differences between men and women. When coordinating five different tasks, men ignored the conversational task more than twice as often as women, while ...
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 / 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 / New 3D COF structure could help tune porous materials for batteries and cleanup
A research team synthesized and determined the structure of a borate-linked 3D crystalline covalent organic framework, TCTP-COF, via electron diffraction for the first time. These findings will help scientists determine the ...
Medical Xpress / Brain glutamate changes could link cannabis use to a higher risk of psychosis
Cannabis, commonly known as marijuana, is a plant that contains psychoactive compounds that can temporarily alter people's brain activity and perceptions. While the consumption of this plant for medical or recreational purposes ...
Medical Xpress / This unusual epigenetic modifier promotes certain cancers but suppresses others
The epigenetic modifier MLL4 has an unassuming name—the 4, for instance, indicates it's just one in a family of such modifiers. But MLL4 is quite special: In a specific type of leukemia, it drives disease progression, while ...
