GlyNAC improves biomarkers in humans and extends lifespan in rodents

Antioxidants proved a bust for life extension almost 25 years ago, but glutathione stands out as an exception. We lose glutathione as we age, and supplementing to increase glutathione levels has multiple benefits, possibly on lifespan. Glutathione is manufactured in the body via an ancient mechanism taking as input cysteine, glutamic acid, and glycine. Supplementing N-Acetyl […]

Drug discovery AI that developed new nerve agents raises difficult questions

Scientific research is generally carried out with the best of intentions – whether it’s to improve health, provide cleaner energy, or increase understanding about the world around us. But what if your work could be intentionally misused to cause harm? This question was brought into sharp focus by researchers working at a drug discovery company […]

Hubble spots farthest star ever seen

NASA’s Hubble Space Telescope has established an extraordinary new benchmark: detecting the light of a star that existed within the first billion years after the universe’s birth in the big bang – the farthest individual star ever seen to date. The find is a huge leap further back in time from the previous single-star record holder; […]

Plasmonic catalyst smashes record for reducing vital chemical feedstock

A method to reduce nitroarenes to amines – a key process in the chemical industry that normally requires extreme conditions and toxic reagents – has been demonstrated under ambient conditions using visible light. The process, which uses the earth-abundant plasmonic photocatalyst copper iron sulfide to supply hot electrons and holes, achieves a cost-normalised production rate […]

Surprising way to make walking easier

Findings by researchers at the University of Nebraska at Omaha (UNO) describe a novel way to reduce the energy people spend to walk, as much as by half, which could have applications for therapy received by patients with impaired walking abilities. The study, published in the prestigious journal Science Robotics, was led by Philippe Malcolm, Ph.D., […]

Audio files are being used as digital drugs

A binaural beat is an illusionary tone created by the brain when presenting two tones separately to each ear that slightly differ in their frequency. It’s claimed binaural beats can have a psychoactive effect on the brain, although there’s limited research on their efficacy and safety. Now a new study published in Drug and Alcohol Review has […]

Anti-cancer ‘dream cream’ shrinks oral tumors

Modern medicine offers “peel and stick” solutions like nicotine or contraceptive patches that you can put right on your skin without needing to visit a doctor for an injection or procedure. Now, researchers have found that applying a topical ointment containing anti-tumor factor can increase the effectiveness of cancer treatment. In a study that will […]

Inflammation linked to neuropsychiatric illness

A potential link between inflammation and the structure of specific regions of the brain has been identified by researchers at the University of Birmingham. The study, published today (30 March 2022) in JAMA Psychiatry, may be particularly relevant for neurodevelopmental psychiatric disorders including autism spectrum and schizophrenia. Researchers say the findings could open up a […]

Where we grow up influences our sense of direction

The streets, alleys, paths and parks of our childhood leave a strong mark on us, with heretofore unsuspected benefits. A research team led by scientists from the Laboratoire d’Informatique en Image et Systèmes d’Information (LIRIS, CNRS/INSA Lyon/Université Claude Bernard Lyon 1) and the Institute of Behavioural Neurosciences at University College London has found that where […]

For those thinking about plastic surgery, selfies give a distorted view

If you’re like a lot of people, an unflattering view on a smartphone “selfie” might start you thinking about rhinoplasty or other cosmetic surgery procedures. But that smartphone shot isn’t giving you the true picture, as selfies introduce measurable distortions in the size and perception of facial features, reports a study in the April issue […]
