Astronomers develop sky model to help ultralong-wavelength observations
The radio sky at frequencies below ~30 MHz, particularly below ~10 MHz, is still largely unknown. Due to the absorption and distortion by the ionosphere, it is quite difficult to receive radio signal of such ultra-long wavelength by telescopes on Ear.....»»

Toxic fireproof chemicals can be absorbed through touch, 3D-printed skin model shows
Cancer-causing flame retardants found in everyday things like plastics, furniture, fabrics and electronics can be sucked up by the skin and absorbed into the bloodstream in 24 hours, scientists have found......»»
Capturing DNA origami folding with a new dynamic model
Most people are familiar with the DNA double-helix. Its twisted ladder shape forms because the long pieces of DNA that make up our genome are exactly complementary—every adenine paired to a thymine, and every cytosine paired to a guanine. Sequences.....»»

The Atlas Robot Is Dead. Long Live the Atlas Robot
Before the dear old model could even power down, Boston Dynamics unleashed a stronger new Atlas robot that can move in ways us puny humans never can......»»
New model finds previous cell division calculations ignore drivers at the molecular scale
When a single bacterial cell divides into two during periods of rapid growth, it doesn't split in half once it reaches a predetermined size. Instead, data has shown, a cell will divide once it has added a certain amount of mass......»»
Report: iPhone 17 Plus to feature a smaller screen than current ‘Plus’ phones
In a new report today, analyst Ross Young says that Apple has an interesting twist planned for next year’s iPhone 17 lineup. According to Young, the iPhone 17 Plus will actually feature a smaller screen than the ‘Plus’ model does now. more.....»»
Generative AI model shows fake news has more impact when released at a steady pace without interruption
It's not at all clear that disinformation has, to date, swung an election that would otherwise have gone another way. But there is a strong sense that it has had a significant impact, nonetheless......»»
Computer model suggests frozen cells could be used to save northern white rhino from extinction
A team of geneticists and computer scientists from the San Diego Zoo Wildlife Alliance, Cornell University and the University of California, Santa Cruz, has created a computer model that shows it should be possible to save the northern white rhino fr.....»»
James Webb Space Telescope data pinpoint possible aurorae on a cold brown dwarf
Using new observations from the James Webb Space Telescope (JWST), astronomers have discovered methane emission on a brown dwarf, an unexpected finding for such a cold and isolated world. Published in the journal Nature, the findings suggest that thi.....»»
Astronomers discover the most metal-poor extreme helium star
Using the Southern African Large Telescope (SALT), astronomers have performed high-resolution observations of a recently detected extreme helium star designated EC 19529–4430. It turned out that EC 19529–4430 is the most metal deficient among the.....»»
NASA observations find what helps heat roots of "moss" on sun
Did you know the sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere "moss." This moss, which was first identified in 1999 by NASA's TRACE mi.....»»
Researchers propose new formation model for massive hot subdwarfs
In a new study published in the The Astrophysical Journal, Dr. Li Zhenwei and his collaborators from Yunnan Observatories of the Chinese Academy of Sciences (CAS), and Dr. Zhang Yangyang from the Zhoukou Normal University, proposed a new formation mo.....»»
