- Atom-thin tech replaces silicon in the world’s first 2D computeram 12. Juni 2025 um 7:17
In a bold challenge to silicon s long-held dominance in electronics, Penn State researchers have built the world s first working CMOS computer entirely from atom-thin 2D materials. Using molybdenum disulfide and tungsten diselenide, they fabricated over 2,000 transistors capable of executing logic operations on a computer free of traditional silicon. While still in early stages, this breakthrough hints at an exciting future of slimmer, faster, and dramatically more energy-efficient electronics powered by materials just one atom thick.
- Smart nanoparticles launch genetic attack on lung cancer and cystic fibrosisam 12. Juni 2025 um 7:16
A scientific team has unlocked a new way to treat serious lung conditions by using specially designed nanoparticles to deliver genetic therapies straight to lung cells. This innovation could transform care for patients with cystic fibrosis or lung cancer. With a powerful combination of gene editing and RNA delivery, the system has already shown promise in animal trials. The streamlined approach not only enhances precision but also avoids harmful side effects, making it a bold leap forward in respiratory medicine.
- Pincer plot twist: How female earwigs evolved deadly claws for love and waram 12. Juni 2025 um 4:12
Female earwigs may be evolving exaggerated weaponry just like males. A study from Toho University found that female forceps, once assumed to be passive tools, show the same kind of outsized growth linked to sexual selection as the male's iconic pincers. This means that female earwigs might be fighting for mates too specifically for access to non-aggressive males challenging long-standing assumptions in evolutionary biology.
- Scientists found the brain glitch that makes you think you’re still hungryam 11. Juni 2025 um 12:41
A team of scientists has identified specialized neurons in the brain that store "meal memories" detailed recollections of when and what we eat. These engrams, found in the ventral hippocampus, help regulate eating behavior by communicating with hunger-related areas of the brain. When these memory traces are impaired due to distraction, brain injury, or memory disorders individuals are more likely to overeat because they can't recall recent meals. The research not only uncovers a critical neural mechanism but also suggests new strategies for treating obesity by enhancing memory around food consumption.
- This "Healthy" Fat May Secretly Be Fueling Obesityam 11. Juni 2025 um 12:41
A popular fat found in olive oil may not be as innocent as it seems. Scientists discovered that oleic acid, a major component of many high-fat foods, uniquely spurs the growth of new fat cells by manipulating specific proteins in the body. Unlike other fats, it boosts the number of "fat cell soldiers," setting the stage for obesity and possibly chronic diseases. This unexpected twist reveals that the type of fat we eat, not just how much, may play a crucial role in our health.
