A team from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in Baltimore has broken new ground in understanding quantum noise — a major source of error in quantum computing. Their findings, published in Physical Review Letters, address a critical challenge that must be solved to develop useful quantum computers.

Children who count on their fingers between ages 4 and 6 1/2 have better addition skills by age 7 than those who don’t use their fingers, suggesting that finger counting is an important stepping stone to higher math skills, according to research published by the American Psychological Association.

Shanghai Ranking by Research Fields for 2025: The Hebrew University ranks among the world’s top 50 in four fields, including Public Administration, which jumped dozens of places to reach 23rd worldwide—higher than Harvard.

A novel study empirically linking a standardized measure of community resilience in more than 3,100 U.S. counties to cognitive, mental, and physical health outcomes shows that counties with fewer healthcare resources, limited digital tools, and weaker support systems exhibit poorer overall health among their residents. The article appearing in the American Journal of Preventive Medicine, published by Elsevier, indicates that resilience can be measured, strengthened, and designed into our systems of care using modifiable tools like healthcare access, support networks, and technology.

Young people who play video games with “gambling-like” elements – such as buying loot boxes or in-game items – are more likely to go on to gamble with real money.
