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 ...
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 / 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 / One-atom substitution successfully tunes molecular heat transport for the first time
Control of heat transport in nanostructures is of central importance for numerous modern technologies—from high-performance computer chips that need to be cooled to energy converters—and is a highly active area of research. ...
Phys.org / This tiny organism simply loves corners, using geometry to sense its world
A surprising observation in the lab has revealed a remarkable ability in Stentor coeruleus, a single-celled organism about one millimeter long. Sometimes nicknamed the "platypus" of microorganisms for its trumpet-like shape, ...
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 / 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 ...
Phys.org / A global carbon credit program risks rewarding the wrong behavior
A United Nations-backed framework for protecting tropical forests could allow governments to collect income from carbon credits without advancing forest conservation. The weakness lies in how the program calculates baselines, ...
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 / Gravity from positivity: Single massive spin-3/2 particle makes gravity logically inevitable, study claims
Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists in nature. Two principles ...
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 ...
