New research led by Oregon Health & Science University reveals a promising approach to developing a universal influenza vaccine—a so-called "one and done" vaccine that confers lifetime immunity against an evolving virus. The study, published today in the journal Nature Communications, tested an OHSU-developed vaccine platform against the virus considered most likely to trigger the [...]
One study will investigate the alterations in brain activity at the cellular level caused by psilocybin, the psychoactive substance found in “magic mushrooms.” How do neurons respond to the effects of magic mushrooms? What occurs in the brain during the perception of motion, or the recognition of grain patterns in wood? How does our [...]
Research indicates a significant reduction in long COVID risk, largely due to vaccination and the virus’s evolution. The study analyzes data from over 441,000 veterans, showing lower rates of long COVID among vaccinated individuals compared to their unvaccinated counterparts across different COVID-19 variants. Decreased Long COVID Risk and the Role of Vaccination The risk of developing long [...]
A new method enables precise nanofabrication inside silicon using spatial light modulation and laser pulses, creating advanced nanostructures for potential use in electronics and photonics. Silicon, the cornerstone of modern electronics, photovoltaics, and photonics, has traditionally been limited to surface-level nanofabrication due to the challenges posed by existing lithographic techniques. Available methods either fail [...]
The element actinium was first discovered at the turn of the 20th century, but even now, nearly 125 years later, researchers still don't have a good grasp on the metal's chemistry. That's because actinium is only available in extremely small amounts and working with the radioactive material requires special facilities. But to improve emerging [...]
A team of researchers from the Institute for Bioengineering of Catalonia (IBEC) has developed light-activated derivatives of the anti-epileptic drug carbamazepine to treat neuropathic pain. Light can be harnessed to target drugs to specific body areas using photopharmacology. This technique modifies the drug’s chemical structure by incorporating a light-sensitive molecular switch, like azobenzene. As [...]
Scientists are developing a process inspired by nature that efficiently recovers europium from old fluorescent lamps. The approach could lead to the long-awaited recycling of rare earth metals. A small molecule that naturally serves as a binding site for metals in enzymes also proves useful for separating certain rare earth metals from each other. [...]
A new study suggests a framework for “Child Safe AI” in response to recent incidents showing that many children perceive chatbots as quasi-human and reliable. A study has indicated that AI chatbots often exhibit an “empathy gap,” potentially causing distress or harm to young users. This highlights the pressing need for the development of [...]
Up to 3% of people with diabetes have an allergic reaction to insulin. A team at Forschungszentrum Jülich has now studied a method that could be used to deliver the active substance into the body in a masked form—in the form of tiny nanoparticles. The insulin is only released in the target organ when [...]
Researchers at Karolinska Institutet in Sweden have developed nanorobots that kill cancer cells in mice. The robot's weapon is hidden in a nanostructure and is exposed only in the tumor microenvironment, sparing healthy cells. The study is published in the journal Nature Nanotechnology. The research group at Karolinska Institutet has previously developed structures that can organize so-called [...]
