Don't move a mussel (or a clam, or a snail)

A new study estimates that the global management of freshwater mussels, clams, and other clinging animals costs $277 million U.S. dollars annually due to their economic impact on shipping, power generation, and water treatment. Biofoulers are filter-feeders that readily colonize pipes and channel walls, causing extensive coverage and o...

First UK study of ketamine for people with severe depression

Researchers at Oxford Health NHS Foundation Trust and the University of Oxford conducted a UK study on the use of ketamine intravenous infusions in people with treatment-resistant depression. The study found that 29% of patients experienced benefit that lasted at least three weeks, while 15% took over 2 months to relapse.

New general concept for the treatment of cancer

Researchers at Karolinska Institutet have identified a new way of treating cancer by inhibiting the MTH1 enzyme, which cancer cells require for survival. This approach differs from previous treatments that target specific genetic defects and offers a potential breakthrough in fighting the disease.

Age-related decline in sleep quality might be reversible

Scientists discovered that age-related sleep decline can be prevented and might even be reversible by targeting the IIS signalling pathway. Administering therapeutic agents improved sleep quality even in old flies, suggesting a potential approach to improve sleep quality in humans.

Dog watch

Researchers found that dogs' attentiveness peaks in mid-adulthood and decreases with age, with adolescent dogs exhibiting the steepest learning curve. This study provides insights into canine cognitive development and its potential applications in understanding human psychological diseases such as ADHD and Alzheimer's.

Got acne? There's an app for that!

The app uses data from peer-reviewed research studies to show people if there is scientific evidence linking acne to foods like chocolate, fat, sugar and whey protein. Research displayed in the app shows that dairy, whey protein, omega-6 fatty acids and foods high in sugar are associated with acne.

Screening for liver cancer in patients with cirrhosis

A systematic review of 47 studies found that surveillance screening for hepatocellular carcinoma (HCC) in cirrhosis patients led to earlier detection, curative treatment, and longer survival. The pooled 3-year survival rate among screened patients was 50.8%, compared to 27.9% among unscreened patients.

Universal syllables

A new study by SISSA researchers found that newborns' brains react differently to words starting with common and uncommon sounds, supporting the idea of universal language preferences. This suggests a possible biological basis for language acquisition, shaping the sound of words from birth.

Study finds link between child's obesity and cognitive function

A new study by University of Illinois researchers finds that obese children are slower to recognize and correct errors, affecting brain activity. Healthy-weight children outperform their obese peers in this critical cognitive task, highlighting the physiological differences between weight status and brain function.

Could depression be treated with Botox?

A new study published in the Journal of Psychiatric Research found that patients injected with Botox showed substantial improvement in their depressive symptoms. The study included 74 depressed subjects who received either Botox or a placebo and showed a 47% decrease in depressive symptoms after six weeks.

Well-rested flies

Scientists at the Max Planck Institute found that inhibiting insulin/IGF signalling improves sleep quality in fruit flies and reverses age-related sleep deterioration. The study suggests a potential link between aging humans' sleep problems and the insulin/IGF pathway.

Pause the paunch and halt the hair loss

Scientists have discovered that changes in the hair growth cycle affect fluctuations in the thickness of underlying fat tissue, allowing skin to regulate fat production. This breakthrough could lead to topical creams that 'pause' fat cell growth, treating obesity and hair loss.
