Persistent intense grief linked to higher healthcare use and mortality

Grief after the loss of a loved one is a natural response – an inevitable part of living and loving. But in a minority of the bereaved, grief is so overwhelming that it can lead to physical and mental illnes, even if they don't necessarily qualify for a diagnosis with the mental health condition 'prolonged grief disorder'.

Decoding DNA packing: Understanding nucleosomes' role in cellular efficiency

Each cell in our bodies carries about two meters of DNA in its nucleus, packed into a tiny volume of just a few hundred cubic micrometers-about a millionth of a milliliter. The cell manages this by winding the strings of DNA around protein spools. The protein-DNA complexes are called nucleosomes, and they ensure that DNA is safely stored.

Global vaccination effort saved 2.5 million lives from SARS-CoV-2

Thanks to vaccinations against SARS-CoV-2 in the period 2020-2024 2.533 million deaths were prevented at global level, one death was avoided for every 5,400 doses of vaccine administered. The 82% of the lives saved by vaccines involved people vaccinated before encountering the virus, 57% during the Omicron period, and 90% involved people aged 60 years and older. In all, vaccines have saved 14.8 million years of life (one year of life saved for 900 doses of vaccine administered).

Study finds past H1N1 exposure shields animals from deadly H5N1

Preexisting immunity to the 2009 H1N1 influenza virus provided near-complete protection against severe H5N1 disease and transmission in ferrets, even after high-dose exposure. In contrast, H3N2 immunity alone offered only partial, inconsistent protection.

Which GLP-1 meds have the most side effects? Study of 60,000 Facebook posts gives answers

Researchers analyzed nearly 60,000 public Facebook posts to identify real-world adverse events linked to GLP-1 receptor agonist (GLP-1 RA) medications. Gastrointestinal symptoms were most common, while mental health concerns and tirzepatide-specific side effects were also flagged.

Experts say you don’t need 10,000 steps, here’s the new magic number

A major systematic review finds that walking just 7,000 steps per day, rather than the traditional 10,000, can significantly reduce the risk of mortality, cardiovascular disease, dementia, and more. The analysis, published in The Lancet Public Health, provides an evidence-based and achievable target for adult health.

Uncovering origins of autism, depression, Parkinson's in fetal brain

The origin of some neuropsychiatric diseases, such as autism, bipolar disorder, or depression, and certain neurodegenerative diseases, Alzheimer's and Parkinson's, can be found in very early stages of brain formation in the fetus. That is, earlier than previously recognized, according to a study by the Hospital del Mar Research Institute and Yale University, published in Nature Communications.
