AI is detecting tumors more often and earlier in the Dutch breast cancer screening program. Those tumors can then be treated at an earlier stage. This has been demonstrated by researchers led by Radboud university medical center in a study published in The Lancet Digital Health. The use of AI could reduce workload and save [...]
A week of lavender-scented nights helped brain surgery patients sleep more deeply, shorten delirium, and feel calmer, pointing to a simple, natural aid for post-surgery care. A randomized controlled trial investigating the therapeutic impact of lavender essential oil aromatherapy on various postoperative measures revealed improved objective sleep quality (notably on the fourth day). It [...]
Scientists have engineered dual-membrane nanoparticles that home in on heart tissue after a heart attack, delivering regenerative molecules while evading the body’s immune defences. Myocardial infarction, better known as a heart attack, is a leading cause of death worldwide. After an injury like this, the heart struggles to regenerate to its previous health. Current [...]
Scientists have identified a natural compound combination that reverses aging-related brain cell decline and removes harmful Alzheimer’s-linked proteins. The treatment, combining nicotinamide (vitamin B3) and the green tea antioxidant epigallocatechin gallate, restores guanosine triphosphate (GTP) levels—critical for neuronal energy and protein cleanup. In aged neurons, the restored energy boosted protein clearance, reduced oxidative stress, [...]
Researchers have developed an eco-friendly method to produce silver nanoparticles from the roots of Martynia annua, showing strong antioxidant and anti-diabetic potential while avoiding the toxic by-products of conventional synthesis. Silver nanoparticles are particularly popular in research because of their high surface area-to-volume ratio, which boosts their reactivity and biological performance. However, producing these tiny particles is energy-intensive, uses [...]
A Copenhagen team has unlocked a clever “backdoor” into studying rare quantum states once thought beyond reach. Scientists at the Niels Bohr Institute, University of Copenhagen, have discovered a new approach for investigating rare quantum states that occur within superconducting vortices. These states were first proposed in the 1960s, but confirming their existence has [...]
A team of researchers has developed a novel water filtration system that combines nanotechnology with 3D printing, aiming to create a low-cost, sustainable solution for greywater treatment. As reported in Micro & Nano Letters, the study demonstrates this with a honeycomb-structured filter made from 3D-printed recycled nylon, coated with titanium dioxide (TiO2) nanoparticles. Nanomaterials such as TiO2 are often studied in water [...]
A new COVID variant is climbing the ranks in the U.S., becoming the third-most common strain of the summer. Variant XFG, colloquially known as "Stratus," was first detected in Southeast Asia in January but accounted for less than about 0% of cases in the United States until May. By late June, it was estimated [...]
Key Questions Answered Q: What did researchers discover about the serotonin 5-HT1A receptor? A: They mapped how it activates different brain signaling pathways, offering insight into how mood and emotion are regulated at the molecular level. Q: Why does this matter for antidepressants and antipsychotics? A: Understanding this receptor’s precise behavior can help design faster-acting [...]
Light can behave in very unexpected ways when you squeeze it into small spaces. In a paper in the journal Science, Mark Brongersma, a professor of materials science and engineering at Stanford University, and doctoral candidate Skyler Selvin describe the novel way they have used sound to manipulate [...]
