A new study has revealed an association between favorable survival outcomes for melanoma patients and the presence of higher populations of tissue-resident memory T cells (TRM). Data obtained from this study could be used not only for a TRM-based machine learning model with predictive powers for melanoma prognosis but could also elucidate the role TRM...

When adults became angry after remembering past experiences, the function of cells lining the blood vessels was negatively impaired, which may restrict blood flow, according to a new study. Previous research has found that this may increase the risk of heart disease and stroke. In this study, episodes of anxiety and sadness did not trigger the same...

Scientists report that a gene previously implicated in the development of atherosclerotic lesions in coronary arteries could be key to understanding why many people don't benefit from the most used therapy for neovascular age-related macular degeneration (AMD), a leading cause of blindness.

Researchers are on a mission to kill drug-resistant bacteria, and a new study has identified a therapy that can penetrate the slime that such infections use to protect themselves from antibiotics.Researchers have shown that an antimicrobial peptide from cows has potential for treating incurable infections from the bacterium Klebsiella pneumoniae. The...

A new device for taking blood samples uses microneedles and a suction cup instead of a large needle. People with a phobia of needles stand to benefit. More blood can be obtained than with the classic finger prick, making diagnostic measurements more reliable. Because the device can be produced at low cost, it is also suitable for developing countries.

Recent reports of NASA's James Webb Space Telescope finding signs of life on a distant planet understandably sparked excitement. A new study challenges this finding, but also outlines how the telescope might verify the presence of the life-produced gas.
