Two new species of large predatory dinosaur discovered on Isle of Wight, UK
A new study led by palaeontologists at the University of Southampton suggests that bones found on the Isle of Wight belong to two new species of spinosaurid, a group of predatory theropod dinosaurs closely related to the giant Spinosaurus. Their unusual, crocodile-like skulls helped the group expand their diets, allowing them hunt prey on both […]
Elephants benefit from having older siblings, especially sisters
A study of semi-captive Asian elephants in Myanmar has found that calves benefit from having older sisters more than older brothers. The findings are published in the British Ecological Society’s Journal of Animal Ecology. Researchers at universities in Finland, the UK and Myanmar have found that Asian elephant siblings influence younger offspring from early through […]
AI’s Help in Colonoscopy Led to Fewer Missed Adenomas
An artificial intelligence-based system missed fewer adenomas and found more first-pass adenomas per colonoscopy than high-definition white light (HDWL) colonoscopies, a multicenter randomized trial found. In an analysis of 223 patients, the adenoma miss rate among those who initially underwent a computer aided detection (CADe) colonoscopy was significantly lower than those who initially underwent HDWL […]
COVID-19 antibodies persist, reduce reinfection risk for up to six months, study finds: The antibodies’ ability to neutralize COVID-19 did not differ significantly over the six-month period.
A Michigan Medicine study found that most patients with mild COVID-19 infections produce antibodies that persist and protect them from reinfection for up to six months. Researchers analyzed nearly 130 subjects with PCR-confirmed COVID-19 illness between three and six months after initial infection. Three patients were hospitalized while the rest were treated as outpatients and […]
Link between ADHD and dementia across generations
A large study at Karolinska Institutet in Sweden has found a link between ADHD and dementia across generations. The study, published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, shows that parents and grandparents of individuals with ADHD were at higher risk of dementia than those with children and grandchildren without ADHD. “The […]
Improving strength, stretchiness and adhesion in hydrogels for wound healing: Scientists use the adhesive capabilities of mussels as a model for optimizing hydrogels’ mechanical properties
Hydrogels are everywhere. They are water-loving polymers which can absorb and retain water and can be found in such everyday consumer products such as soft contact lenses, disposable diapers, certain foods, and even in agricultural applications. They are also extremely useful in several medical applications due to their high degree of biocompatibility and their ability […]
How microbes can exacerbate cognitive decline
Recent research has found that changes in the gut microbiota — the trillions of bacteria and other microbes that live in the intestines — can alter the brain and behavior. Now, a study led by scientists at UCLA could elucidate how and why that phenomenon occurs. In the experiment, which was conducted with mice, researchers […]
Growing evidence of vitamin K benefits for heart health
New Edith Cowan University (ECU) research has found that people who eat a diet rich in vitamin K have up to a 34 percent lower risk of atherosclerosis-related cardiovascular disease (conditions affecting the heart or blood vessels). Researchers examined data from more than 50,000 people taking part in the Danish Diet, Cancer, and Health study […]
No more finger pricks: A continuous glucose monitor benefits patients with diabetes in more ways than one
A 15-center study of 175 patients with poorly controlled type 2 diabetes in JAMA found that continuous glucose monitoring, compared to blood glucose meter monitoring, or finger pricking, significantly decreased their hemoglobin A1C over eight months (-1.1% versus -0.16%, respectively.) Although the benefits of continuous glucose monitoring for patients with diabetes has been demonstrated before, […]
Eating disorder behaviors alter reward response in brain: Changes can affect food intake control circuitry and cause disorders to progress
Researchers have found that eating disorder behaviors, such as binge-eating, alter the brain’s reward response process and food intake control circuitry, which can reinforce these behaviors. Understanding how eating disorder behaviors and neurobiology interact can shed light on why these disorders often become chronic and could aid in the future development of treatments. The study, […]
