Scientists Overturn 20 Years of Textbook Biology With Stunning Discovery About Cell Division

Scientists have uncovered an unexpected function for a crucial protein involved in cell division. Reported in two consecutive publications, the finding challenges long-accepted models and standard descriptions found in biology textbooks. Researchers at the Ruđer Bošković Institute (RBI) in Zagreb

Nighttime phone use linked to higher levels of suicidal thoughts in high-risk adults

Patterns of smartphone use and their impact on mental health are being extensively studied due to the growing dependence of the device in people’s lives.

A recent study tracked late-night smartphone usage in 79 adults with recent suicidal thoughts for 28 days. People using phones late between 11 p.m. and 1 a.m. showed a higher risk of suicidal thoughts the next day, whereas those who actively used the keyboard beyond midnight hours showed a lower risk.

The findings are published in JAMA Network Open.

Oxygen deprivation drives dysfunctional neutrophil immunity

Low oxygen levels in the blood can alter the genetic makeup of key immune cells, weakening the body’s ability to fight infection, new research shows.

Scientists found that oxygen deprivation – known as hypoxia – changes the genetic material of immune cells called neutrophils, reducing their capacity to destroy harmful microbes.

The team discovered that low oxygen appears to leave a lasting mark on the bone marrow cells that produce neutrophils, meaning the impact can persist after oxygen levels return to normal.
