Keeping the beat

The National Institutes of Health (NIH) has renewed funding for the University of Pittsburgh's Cardiovascular Bioengineering Training Program, which educates students in cardiovascular research and prepares them for careers in basic and translational cardiovascular research. The program focuses on three areas: understanding native and ...

Snakebites cost Sri Lanka more than $10 million

A new study found that snakebites in rural Sri Lanka result in significant economic losses for individuals and the healthcare system. The annual costs are estimated at over $10 million, with victims experiencing median out-of-pocket costs of $11.82 and a loss of income of up to $33.21.

How much does dementia risk increase after traumatic brain injury?

A retrospective cohort study of over 40,000 TBI patients found a significant increase in dementia risk after moderate-to-severe traumatic brain injury. Those with mild TBI had a 1.6% diagnosis rate, while those with moderate-to-severe TBI had a 3.5% diagnosis rate, highlighting the increased risk in middle-aged individuals.

Pipetting in space

Astronauts are exposed to DNA damage due to zero gravity and cosmic radiation; an automated diagnostic procedure is being adapted for use in space, promising constant conditions for each sample. The device could also be used to evaluate the effects of radiotherapy.

Penn collaboration produces surprising insights into the properties of butterfly wings

Researchers at the University of Pennsylvania have made surprising discoveries about the properties of butterfly wings, shedding light on their structural origins. The study reveals that the whiteness on male butterflies' wings changes depending on the angle, and that this phenomenon is crucial for signaling and mating purposes.

Cancer researchers overestimate reproducibility of preclinical studies

A survey of experts and novices found that cancer scientists overestimated the replicability of high-profile preclinical studies. In reality, none of the six completed studies by the Reproducibility Project: Cancer Biology reproduced the original results. Training might help overcome cognitive biases in interpreting scientific reports.

Human genes for coronary artery disease make them more prolific parents

A genetic study suggests that human genes for coronary artery disease contribute to greater numbers of children, providing an evolutionary trade-off between early-life reproductive benefits and later-life disease costs. The study uses genome-wide scans and lifetime reproductive data to identify genetic variation linked to the disease.

Bacterial superantigens turn our immune cells to the dark side

Researchers found that mucosa-associated invariant T (MAIT) cells can mount a rapid and robust inflammatory response to bacterial superantigens, contributing to severe organ damage or death. The overzealous response leads to exhaustion of MAIT cells, resulting in immunosuppression and increased susceptibility to secondary infections.

What makes a movement feel strenuous?

A study published in PLOS Biology found that duration, biomechanics, and force influence the subjective effort associated with arm movements, while movement amplitudes have no effect. The researchers also discovered a link between brain functions involved in decision-making and movement execution.
