Permanent Twitter ban of extremist influencers can detoxify social media

A Rutgers-led study found that banning right-wing extremists from Twitter significantly reduces the spread of anti-social ideas and conspiracy theories. Removing these individuals from social media platforms leads to a nearly 92% decline in tweets referencing them, as well as a 90% decrease in new users tweeting about them.

TEDDY study compares characteristics of children diagnosed with type 1 diabetes before and after age 6

The study analyzed data from 8,502 genetically high-risk children and found that half developed type 1 diabetes before age 6, while the other half developed it between ages 6 and 12. The findings suggest a different form of type 1 diabetes emerges in children as they grow older.

The next big thing: How do scientists bring hydrogen fuel cells from laboratory to public life?

Researchers at USTC have successfully synthesized small-sized Pt intermetallic nanoparticle catalysts with ultralow Pt loading and high mass activity. These catalysts exhibited excellent electrocatalytic performance for oxygen reduction reaction in proton-exchange membrane fuel cells, potentially decreasing the cost of fuel cells.

Measuring financial and digital literacy in vulnerable populations

A new approach to measuring financial and digital literacy is proposed by a team of researchers led by Angela Lyons. The study finds that while promoting literacy is important, it may not be enough to ensure resilience, particularly for vulnerable groups such as women and those living in poverty.
