Activity of fuel cell catalysts doubled

Researchers at TUM have developed platinum nanoparticles that double the performance of current fuel cells. The particles are about one nanometer big and contain approximately 40 platinum atoms, resulting in high mass activity. This breakthrough could lead to widespread adoption of fuel cells in electric cars.

New study unravels protection mechanism in bacteria

A recent study by the University of Birmingham has identified a key pathway involved in protecting bacteria against antibiotics. The researchers discovered that phospholipids are transported towards the outer membrane through a series of proteins, which could lead to the development of new antibiotic treatments.

Taking to the treadmill can ease period pain

A new study published in Contemporary Clinical Trials found that treadmill exercise reduced period pain by 6% after four weeks and 22% after seven months. Women who participated in the supervised aerobic training regime also reported improved quality of life and daily functioning, but not increased sleep quality.

Diet quality may affect risk of frailty in older adults

A study published in the Journal of the American Geriatric Society found that poorer overall diet quality was associated with a higher incidence of frailty in older adults. Improving diet quality may help lower the risk of frailty, with good-quality diets shown to have a significantly lower risk compared to poor- and medium-quality diets.

Super-resolution microscopy illuminates associations between chromosomes

Scientists have used super-resolution microscopy to identify physical connections between five human chromosomes, revealing a shared sequence encoding ribosomal DNA that holds the chromosomes together. The findings suggest that these inter-chromosomal linkages are pervasive in healthy and diseased tissue, and may play a role in chromos...

Tweeting while watching TV diminishes enjoyment

A new study from the University of Connecticut found that tweeting while watching TV decreases viewers' ability to become immersed in the narrative. College students who engaged in media multitasking reported lower levels of transportation into the content and intensified emotions compared to those consuming only one medium.

Higher risk of stillbirth in longer pregnancies, study finds

A meta-analysis of 15 million pregnancies found that the longer a pregnancy continues past 37 weeks gestation, the higher the risk of stillbirth. The risk increased with advancing gestation, with a 64% increase in stillbirths between 40-41 weeks and 3.18 stillbirths per 1000 pregnancies at 42 weeks.
