Using additive manufacturing to detect counterfeit parts
Researchers have developed a method of imprinting a hidden magnetic tag, encoded with authentication information, within manufactured hardware during the part fabrication process. The revolutionary process holds the potential to expose counterfeit good…
Rwandan tree carbon stock mapped from above
Researchers have developed accurate nation-wide mapping of the carbon content of trees based on aerial images.
Scientists enhance recyclability of post-consumer plastic
Scientists have developed a new method for recycling high-density polyethylene (HDPE).
Researchers show a new way to induce useful defects using invisible material properties
Much of modern electronic and computing technology is based on one idea: add chemical impurities, or defects, to semiconductors to change their ability to conduct electricity. These altered materials are then combined in different ways to produce the d…
When grandpa can’t hear words at a noisy holiday gathering, too many brain cells may be firing at once
Looking for answers about how the brain works amid age-related hearing loss, researchers say they found that old mice were less capable than young mice of ‘turning off’ certain actively firing brain cells in the midst of ambient noise. The result, they…
Current Antarctic conservation efforts are insufficient to avoid biodiversity declines, study shows
Existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are likely for 65% of the continent’s plants and wildlife by the year 2100, according to a new study.
Shrinking hydrogels enlarge nanofabrication options
Researchers have developed a strategy for creating ultrahigh-resolution, complex 3D nanostructures out of various materials.
Glassfrogs achieve transparency by packing red blood cells into mirror-coated liver
New research shows that glassfrogs — known for their highly transparent undersides and muscles — perform their ‘disappearing acts’ by stowing away nearly all of their red blood cells into their uniquely reflective livers. The work could lead to new a…
Can the AI driving ChatGPT help to detect early signs of Alzheimer’s disease?
The artificial intelligence algorithms behind the chatbot program ChatGPT — which has drawn attention for its ability to generate humanlike written responses to some of the most creative queries — might one day be able to help doctors detect Alzheime…
Hawai’i earthquake swarm caused by magma moving through ‘sills’
A machine-learning algorithm reveals the shape of massive subterranean structures linking active volcanoes.
