NUS Medicine researchers use nutritional supplement to shrink breast cancer tumors

Researchers at NUS Medicine have successfully used a plant-derived nutrient supplement to shrink breast cancer tumors in preclinical models. The treatment, which uses nanotechnology to convert the natural component into chemotherapy only at the tumor site, shows promise for reducing side effects and increasing patient lifespan.

Weddell seal moms sacrifice their diving capacity to provide iron to their pups: Climate change could make seals more vulnerable

Researchers found that Weddell seal moms limit their own diving and underwater foraging capabilities to provide iron to their pups during lactation. This sacrificial behavior may make the seals more vulnerable to climate regime shifts that could decouple the seasonal pulse of productivity in the Antarctic environment.

Cancer research repurposed to expose age-related blood diseases

Scientists at IRB Barcelona develop a new approach to pinpointing the genes driving clonal hematopoiesis, a biological process linked to ageing and increased risk of blood malignancies. By adapting cancer genomics tools, researchers aim to improve early detection and monitoring of this condition.

Children with rare genetic disorders more likely to be diagnosed with developmental, behavioural and mental health problems

Children with rare genetic disorders are more likely to be diagnosed with developmental, behavioural and mental health problems. A study of 2,800 young people found that those with intellectual disabilities were almost 30 times as likely to be autistic and over 13 times more likely to have ADHD.

Research brief: Studying outcomes of visceral artery pseudoaneurysm in necrotizing pancreatitis

Researchers found that visceral artery pseudoaneurysms in necrotizing pancreatitis are associated with significant morbidity and mortality. The study also highlighted the importance of early detection and treatment, as delayed diagnosis can lead to increased complications and mortality.

Why are some birds more intelligent than others?

A recent study by McGill University researchers found that birds with higher numbers of neurons in the pallium, a brain region involved in memory and learning, are also more innovative. Longer development times in the nest may play a crucial role in the evolution of intelligence.

Microscopic blood vessel disease in the brain’s white matter associated with worse cognition in Alzheimer’s

Researchers found that microscopic blood vessel disease in the brain's white matter is associated with worse cognitive function and memory deficits in individuals with Alzheimer's. Lifestyle changes such as reducing hypertension, obesity, diabetes, and inactivity may help prevent or slow disease progression.

New study used marine monitor radar system to monitor California marine protected areas

Researchers used marine monitor radar system to track vessel activity near California's marine protected areas. The study found that 40% more boat activity occurred in the vicinity of MPAs compared to surrounding areas, suggesting fishers are aware of MPA boundaries and cluster just outside them for better fishing opportunities.

It’s raining PFAS

The levels of per- and polyfluoroalkyl substances (PFAS) in environmental media have dramatically decreased over the last 20 years due to new insights into their toxicity. However, due to the global spread of PFAS, environmental media everywhere will now exceed guidelines designed to protect human health.

Weed zapping

Researchers found that electrocution treatments can eliminate up to 97% of late-season, herbicide-resistant waterhemp plants. The treatments also reduced weed seed viability by 54-80%, with some studies showing yield losses of 11-26%.

New dog food? Study shows Fido's gut bacteria could turn over within a week

A new study from the University of Illinois found that dog gut bacteria can change rapidly after introducing a new diet, with microbial turnover occurring in under a week. The research also confirmed previous findings on the health benefits of high-fiber diets over high-fat and high-protein diets.

Could acupuncture help ward off diabetes?

A new study from Edith Cowan University found that acupuncture therapy significantly improved fasting plasma glucose, two-hour plasma glucose, and glycated haemoglobin levels in people with prediabetes. The therapy also showed a greater decline in the incidence of prediabetes without adverse reactions.

Comparison of two nano rulers

Scientists at University Hospital Bonn compared PELDOR and FRET spectroscopy methods to measure distances in protein molecules. While most results were comparable, inconsistencies were found in two cases, highlighting the importance of re-measurement with another nano ruler.
