Phys.org / Cosmologists collaborate to sharpen measurements of the Hubble constant
Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in Astronomy & Astrophysics, ...
Phys.org / Ytterbium atomic clock could open a new window on fundamental physics
For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ytterbium to create a new type of atomic clock that is both highly precise and extremely sensitive to ...
Phys.org / Engineered tobacco plant can produce five psychedelics, including psilocybin and DMT
Compounds in psychedelic drugs like DMT, psilocybin, and psilocin are naturally produced in certain plants, fungi, and animals, and have a long history of use in spiritual and therapeutic contexts. Now, a considerable amount ...
Phys.org / Scientists study radiation limits for safer seafood shipping
Scientists at Florida International University have identified a promising way to safely ship fish long distances without losing vital vitamin D, using a method already widely applied to preserve other foods—gamma irradiation.
Phys.org / How the octopus uses its 'taste by touch' sensory system to feel out potential mates
A new study by Harvard biologists reveals how octopuses feel their way to potential mates with a "taste by touch" sensory system and can even couple at arm's length without actually seeing each other. In a study featured ...
Phys.org / Cell lineage tracing reveals early‑segregated germline in plants
August Weismann's germ plasm theory of the late 19th century posited that only germ cells, e.g., sperm and egg cells in animals or pollen and ovule cells in plants, transmit genetic information to the next generation, and ...
Phys.org / Dalí's 'sublime' amber medium may explain unusual aging in a museum masterpiece
As part of the FED-tWIN Face-to-Face project, a multidisciplinary team bringing together the European Centre of Archaeometry (University of Liège, ULiège), the Royal Museums of Fine Arts of Belgium (RMFAB), CNRS-Sorbonne ...
Phys.org / Platform for precise cellular control uses non-genetic DNA decoupled from genetic information
Stepping away from its billions-of-years-old role as a genetic blueprint, DNA is now embarking on a new journey as an active field agent within cells. This research by a team led by Professor Jongmin Kim and Ph.D. candidate ...
Phys.org / Ghostly particles: Dark radiation may have masqueraded as neutrinos
New research suggests that neutrinos in the early universe may have transformed into a previously unknown form of radiation. A study from Washington University in St. Louis offers a new way to explain certain puzzling observations ...
Phys.org / Engineered E. coli dependency may help contain microbes to defined areas
Take a typical fish out of the water and it won't live long. It gets the oxygen it needs from the water it swims in. In a similar way, scientists are exploring dependency as a method of controlling what microbes can do and ...
Dialog / New 2D material demonstrates capability for ultrathin waveplates
Polarization has always been a core property of light that is essential for a broad range of everyday applications, including displays (LED, LCD, 3D Cinematics), photography, as well as satellite and antenna technologies. ...
Phys.org / Artemis II to test new models that predict solar particle storms up to a day ahead
During the Artemis II mission launched Wednesday, NASA will test out a pair of new solar radiation forecasts, developed at University of Michigan Engineering, designed to protect astronauts venturing away from Earth. The ...
