A centromere is a specialized location in the DNA that functions as the control center of cell division and is maintained, unchanged, across generations of cells. It is characterized by a special protein, called centromeric protein A (CENP-A), which marks the centromere and mobilizes other players necessary for cell division. Read more ›

Fatty liver disease is a growing global health concern. Proglucagon-derived peptides (PGDPs), including glucagon, GLP-1, and GLP-2, are known to regulate lipid metabolism in the liver. However, the mechanism underlying this remains unelucidated. Now, researchers have investigated the role of PGDPs, including glucagon, GLP-1, and GLP-2, in fat accumulation in the liver using GCGKO mice deficient in these peptides. Read more ›

Over the past decade, decreasing vaccination rates now threaten the huge beneficial impacts of vaccinations in the U.S. and globally. Researchers discuss the multifactorial barriers including increasing vaccine hesitancy and new clinical and public health challenges in vaccinations of U.S. adults. Read more ›

Researchers studied the fate of the material produced by Posidonia seagrass meadows. This study, carried out in the Mediterranean Sea at STARESO, shows that the dead leaves of what is commonly known as Neptune grass accumulate in shallow areas, where they break down like a compost, remineralizing the organic matter. This has a previously underestimated effect on carbon fluxes in the Mediterranean coastal environments. Surprisingly, alongside this CO2 emission, oxygen... Read more ›

Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe was only 700 million years old. This is surprising since, according to our current understanding of galaxy formation, such early galaxies are expected to appear more chaotic. Read more ›

Researchers have made the surprising discovery that one species of comb jelly (Mnemiopsis leidyi) can fuse, such that two individuals readily turn into one following an injury. Afterwards, they rapidly synchronize their muscle contractions and merge digestive tracts to share food. Read more ›

Doctors have long believed the cancer drug 5-fluorouracil works by damaging the building blocks of DNA, but researchers have now found that in certain cancers, it kills cells by interfering with RNA synthesis. The findings could help researchers design better drug combinations for colon and gastrointestinal cancers. Read more ›

A blood test, performed when metastatic prostate cancer is first diagnosed, can predict which patients are likely to respond to treatment and survive the longest. It can help providers decide which patients should receive standard treatment versus who might stand to benefit from riskier, more aggressive new drug trials. Read more ›

Researchers found that the possibility of parental disclosure through online patient portals led older adolescents to hesitate in sharing complete health information with doctors, putting them at risk of missed diagnoses and treatments. The paper noted that confidentiality concerns were increased among females and those who are sexual and gender minorities. Read more ›

The study concludes that among older adults, voice recorders are effective at capturing the circumstances and context in which they lost their balance and potentially fell, without relying on recall later. Read more ›
