Worm 'cell death' discovery could lead to new drugs for deadly parasite

Researchers from the Walter and Eliza Hall Institute have identified a 'programmed cell death' pathway in parasitic worms that could one day lead to new treatments for schistosomiasis. The discovery was made by studying programmed cell death in human cells, where the team found similarities with the process in fluke worms.

High social status makes people more trusting, study finds

Researchers found that high-status individuals tend to trust others more in initial encounters due to positive expectations of others' motives. In a workplace setting, this means that bosses may be more trusting during initial encounters with employees.

A labor saving way to monitor vast rangelands

USDA researchers explore the use of unmanned aerial vehicles (UAVs) to monitor changing land-use patterns in western rangelands.

Doctor experience matters in carotid artery procedures

A study published in the Journal of the American Medical Association found that older patients who underwent carotid artery stenting from lesser experienced physicians had a higher risk of death within 30 days. The study analyzed Medicare data and found that doctors with less than six procedures per year performed worse outcomes.

Saw palmetto no benefit as prostate remedy

A new study published in the Journal of the American Medical Association found that saw palmetto extract did not relieve symptoms of an enlarged prostate, even at high doses. The research involved over 300 men with moderate symptoms and took a placebo or saw palmetto for nearly 17 months.

Central Asia's hidden burden of neglected tropical diseases

The region's high rates of parasitic infection are nearly 20 years after the collapse of the Soviet Union, particularly among economically disadvantaged groups. Soil-transmitted helminth infections have been linked to developmental delays and decreased economic productivity in countries like Uzbekistan.

Cell dysfunction linked to obesity and metabolic disorders

Scientists at Karolinska Institutet found that fat cells in overweight people have a higher capacity for storing fats but a lower capacity for ridding themselves of them. This can lead to an accumulation of triglycerides and cholesterol in the blood, increasing the risk of metabolic diseases.

Researchers uncover gene associated with blood cancers

A genomic study identified the SF3B1 gene as frequently mutated in myelodysplasia, a precursor to leukaemia. The mutation is associated with ring sideroblasts and anaemia, leading to more straightforward diagnosis through a single blood test.

A treatment for one form of albinism?

Researchers have found that treating mice with OCA-1B, a form of oculocutaneous albinism, with nitisinone improves eye and skin pigmentation. The study suggests that nitisinone could potentially ameliorate vision loss in patients with OCA-1B.

Glow-in-the-dark millipede says 'stay away'
