A Proof of Concept Attempt to Assess the Impact of First Generation Senolytic Drugs by Looking at Past Usage

Senolytic drugs are those capable of selectively destroying senescent cells. A range of such therapies are at various stages of development, including those that have reached initial human clinical trials. Senescent cell accumulation is an important cause of degenerative aging, and the removal of such cells via senolytic treatments has […]

Axin for a friend: Protein could hold the key to longer, healthier life

Axin is a VIP – a Very Important Protein. It’s essential to the development of an embryo. It’s a key player in allowing the body’s cells to divide without going haywire and forming a tumour. It regulates the body’s production of lipids, or fats, which can affect aging. Essentially, it […]

A pursuit of better testing to sort out the complexities of ADHD

The introduction of computer simulation to the identification of symptoms in children with attention-deficit/hyperactivity disorder (ADHD) has potential to provide an additional objective tool to gauge the presence and severity of behavioural problems, Ohio State University researchers suggest in a new publication. Most mental health disorders are diagnosed and treated based […]

Study links metabolic syndrome to higher cardiovascular risk in patients with psoriasis

Psoriasis, a chronic inflammatory skin disease, has long been known to increase the risk of cardiovascular disease, which includes heart attack and stroke. Now, researchers have identified a key culprit: the presence of metabolic syndrome (MetSyn), a condition that includes obesity, diabetes, high cholesterol, and hypertension, and is highly prevalent […]

AI-powered microscope could check cancer margins in minutes

When surgeons remove cancer, one of the first questions is, “Did they get it all?” Researchers from Rice University and the University of Texas MD Anderson Cancer Center have created a new microscope that can quickly and inexpensively image large tissue sections, potentially during surgery, to find the answer. The […]

Blood Pressure Drug may be Key to Increasing Lifespan, New Study Shows

Metolazone, a drug used to treat hypertension, activates a mitochondrial stress response that prolongs lifespan in the roundworm Caenorhabditis elegans A stress response of mitochondria, the part of our cells that produce energy to power bodily functions, is important to a longer life. A team of scientists from Osaka City […]

Light flips genetic switch in bacteria inside transparent worms

Baylor College of Medicine researcher Meng Wang had already shown that bacteria that make a metabolite called colanic acid (CA) could extend the lifespan of worms in her lab by as much as 50%, but her collaboration with Rice University synthetic biologist Jeffrey Tabor is providing tools to answer the bigger question of how […]

High levels of dementia found in the Torres Strait

James Cook University’s Professor Edward Strivens and Associate Professor Sarah Russell from JCU’s Healthy Ageing Research Team have found were part of a group that examined 276 Torres Strait residents aged between 45 and 93. The study took in all 18 island and 5 mainland communities in the Torres Strait […]

Artificial intelligence may diagnose the leading cause of blindness much earlier

Artificial intelligence is able to analyze vast amounts of information very quickly and efficiently. And, therefore, unsurprisingly it is very useful in medicine. Scientists from UCL and the Western Eye Hospital have now developed a new eye test, which takes advantage of AI technology to predict wet age-related macular degeneration […]

Testosterone therapy may help preventing type 2 diabetes

Type 2 diabetes is oftentimes called a lifestyle disease, because it is associated with obesity, poor levels of physical activity and a terrible diet. It can be prevented through lifestyle changes, but what are other options? A team of scientists led by the University of Adelaide conducted a 2 year […]

Scientists discover how our brains track where we and others go

For the first time, scientists have recorded how our brains navigate physical space and keep track of others’ location. Researchers used a special backpack to wirelessly monitor the brain waves of epilepsy patients as each one walked around an empty room hunting for a hidden, two-foot spot. In an article […]

Scientists at TAU develop new gene therapy for deafness

A new study from Tel Aviv University (TAU) presents an innovative treatment for deafness, based on the delivery of genetic material into the cells of the inner ear. The genetic material “replaces” the genetic defect and enables the cells to continue functioning normally. The scientists were able to prevent the gradual deterioration […]

Ketamine: New use for an old drug

Researchers at three Canadian universities find the key to unlocking the antidepressant effect of ketamine in the brain. A group of proteins called 4E-BPs involved in memory formation are key to unlocking the antidepressant effect of ketamine in the brain, according to a new study by researchers from three Canadian […]

Decoding our immune response is nothing but a genetic ‘turn off’

How genes get ‘switched on’ has fascinated scientists for decades, but equally important questions about how they are ‘turned off’ have been largely overlooked. As the messengers carrying instructions from DNA for the creation of proteins, the formation and decay of cellular RNAs is critical to maintaining cell stability and […]

Spatial maps give new view of gut microbiome

What microbes are in your gut, and where? Cornell researchers developed an imaging tool to create intricate spatial maps of the locations and identities of hundreds of different microbial species, such as those that make up the gut microbiome. The tool will help scientists understand how complex communities of microorganisms […]

Sex peptide causes female fruit fly’s gut to grow

Scientists have known that females of many species eat more to meet the demands of reproduction, and that females undergo widespread physiological and behavioral changes after mating. The mechanisms of these changes, however, are not well understood. A new study of the common fruit fly (Drosophila melanogaster) has identified a […]

What social distancing does to a brain

Have you recently wondered how social-distancing and self-isolation may be affecting your brain? An international research team led by Erin Schuman from the Max Planck Institute for Brain Research discovered a brain molecule that functions as a “thermometer” for the presence of others in an animal’s environment. Zebrafish “feel” the […]
