Are humans naturally violent? New research challenges long-held assumptions‎

New research from the University of Lincoln, UK, is challenging a common assumption about the evolutionary origins of human violence, suggesting that everyday aggression does not inevitably lead to lethal conflict. The study, published in the journal Evolution Letters, finds that mild aggression and lethal violence appear to have evolved along different pathways, offering new insight into one of the most enduring debates about human nature.

Women assistant principals average 13.2 teaching years before first principal bid‎

During Women's History Month, University of Delaware Associate Professor Lauren P. Bailes is taking a closer look at why males continue to outnumber females in school leadership roles, despite equivalent years of experience. "To our knowledge, this is the first study that examines assistant principals' applications when they are still part of the pool, before the hiring process has taken place," said Bailes, who studies educational leadership in UD's College of Education and Human Development (CEHD).

How DICER cuts microRNAs with single-nucleotide precision‎

A research team from The Hong Kong University of Science and Technology (HKUST) has made an advance in understanding the molecular machinery of RNA silencing. The team uncovered how the human enzyme DICER achieves highly precise processing of microRNAs (miRNAs), advancing gene regulation research and offering new insights into the mechanisms underlying cancer, immune disorders, and genetic diseases.

JWST probes emerging young star clusters in nearby spiral galaxy NGC 628‎

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby spiral galaxy known as NGC 628. Results of the observational campaign, published March 10 on the arXiv pre-print server, shed more light on the population of emerging young star clusters in this galaxy.

Musk's Twitter takeover highlights danger of owner-dominated social media platforms‎

A new study has suggested that the transformation of Twitter into X under Elon Musk marks the rise of a new, illiberal regime of governing social media platforms, which can be controlled by one person and used to push their own political agenda. Alongside researchers from the WZB Berlin Social Science Center and the Weizenbaum Institute, Dr. João C. Magalhães of The University of Manchester studied more than 1,500 events to track how the platform has changed since Musk acquired it.

Why drawing eyes on food packaging could stop seagulls stealing your chips‎

The increasingly urban lifestyles of seagulls in the UK and around Europe has made them experts at grabbing food from unsuspecting outdoor diners. Herring gulls in particular are gaining a reputation for food theft in seaside towns like Falmouth in Cornwall, where I live.

Dishwashing with side effects: Kitchen sponges release microplastics‎

Kitchen sponges are considered a potential, yet largely understudied, source of microplastics in households. A study in Environmental Advances investigated how many microplastic particles are released from kitchen sponges during use and what environmental impacts result. The paper is titled "From sink to sea: Microplastic release from kitchen sponges and potential environmental effects."
