Why the harsh Snowball Earth kick-started our earliest multicellular ancestors

Leave a Comment / News / By

Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human society. A new article shows how specific physical conditions — especially ocean viscosity and resource deprivation — during the global glaciation period known …

Public perception of scientists’ credibility slips

Leave a Comment / Technology / By

New analyses find that public perceptions of scientists’ credibility — measured as their competence, trustworthiness, and the extent to which they are perceived to share an individual’s values — remain high, but their perceived competence and trustworthiness eroded somewhat between 2023 and 2024. The research also found that public perceptions of scientists working in artificial …

Cheaper, more convenient method to detect asbestos

Leave a Comment / Technology / By

Transmission electron microscopy (TEM) has long been the gold standard for detecting asbestos fibers in air samples drawn at construction sites. But researchers have found that a cheaper, less labor-intensive method, scanning electron microscopy (SEM), can work just as well in most cases. The new finding could help reduce the estimated $3 billion spent on …

Watching others’ biased behavior unconsciously creates prejudice

Leave a Comment / News / By

We unconsciously form prejudice toward groups when we see biased people interact with members of a group. That is according to new research by psychologists, who show for the first time that observational learning is an important mechanism of prejudice formation. ​We unconsciously form prejudice toward groups when we see biased people interact with members …

Safer, swifter, smaller scar: New brain surgery approach targets difficult tumors at skull base

Leave a Comment / News / By

A medical team has developed a minimally invasive neurosurgical technique using an endoscope for the removal of tumors in the base of the skull. The results compare favorably with the conventional microscopic approach, with the added benefit of shorter operative times, less blood loss, and smaller craniotomies. ​A medical team has developed a minimally invasive …
