| Fully 3D-printed, flexible OLED display Posted: 07 Jan 2022 01:46 PM PST Researchers used a customized printer to fully 3D print a flexible organic light-emitting diode (OLED) display. The discovery could result in low-cost OLED displays in the future that could be widely produced using 3D printers by anyone at home, instead of by technicians in expensive microfabrication facilities. |
| Eccentric exoplanet discovered Posted: 07 Jan 2022 09:14 AM PST An international research team has discovered a sub-Neptune exoplanet orbiting a red dwarf star. |
| California mice eat monarch butterflies Posted: 06 Jan 2022 11:37 AM PST At the largest winter monarch aggregation in central Mexico, scientists have observed that rodents attack monarchs that fall to the ground. Biologists have now discovered that the western harvest mouse also eats grounded monarchs. Documenting this new feeding behavior is a reminder of little we know about the interactions that may be lost as insect populations decline. |
| Superbug MRSA arose in hedgehogs long before clinical use of antibiotics Posted: 05 Jan 2022 08:14 AM PST Scientists have found evidence that a type of the antibiotic resistant superbug MRSA arose in nature long before the use of antibiotics in humans and livestock, which has traditionally been blamed for its emergence. Hedgehogs carry a fungus and a bacteria on their skin, and the two are locked in a battle for survival. The fungus secretes antibiotics to kill the bacteria, but in response the bacteria has evolved antibiotic resistance -- becoming Methicillin-resistant Staphylococcus aureus, or MRSA. Up to 60% of hedgehogs carry a type of MRSA called mecC-MRSA, which causes 1 in 200 of all MRSA infections in humans. Natural biological processes, not antibiotic use, drove the initial emergence of this superbug on hedgehogs around 200 years ago. |
| 'Nano-chocolates' that store hydrogen Posted: 27 Dec 2021 12:43 PM PST An innovative approach could turn nanoparticles into simple storage devices for hydrogen. The concept uses nanoparticles made of the precious metal palladium. |
