Can online games be an effective intervention to help adolescents reduce substance abuse?

Computers and Math from Science Daily Feed - Wed, 03/19/2025 - 11:32am
For adolescents struggling with substance abuse, traditional in-person interventions such as counseling are not always effective, and rural areas often lack access to these services. A researcher is thinking outside the box, aiming to help game designers develop fun, digital games that make ditching bad habits easier by meeting adolescents where they already are: online.

EPA regulations cut power sector emissions but miss opportunities for deeper reductions

Matter and energy from Science Daily Feed - Wed, 03/19/2025 - 11:30am
Regulations finalized by the Environmental Protection Agency in 2024 could cut emissions from the power sector by 51% over 2022 levels, compared to only 26% without the rules, according to a new analysis. The study helps identify the likely effects of current regulations, highlights the impact of potential repeal on U.S. emissions, and quantifies the overall efficiency of emissions reductions achieved by the current rules.

Squirrel-inspired leaping robot can stick a landing on a branch

Matter and energy from Science Daily Feed - Wed, 03/19/2025 - 11:28am
A leaping robot could have application in search and rescue, construction, even forest monitoring. But how do you design a robot to stick a landing on a branch or pipe? Biologists worked with robot designers to discover how squirrels do it, and used what they learned to design a one-legged robot with the balancing ability and leg biomechanics to correct for over- and undershooting and land successfully on a narrow perch.

Webb Directly Observers Giant Planets, Sensing Carbon Dioxide in their Atmospheres

Universe Today Feed - Wed, 03/19/2025 - 10:16am

The James Webb Space Telescope (JWST) has achieved groundbreaking discoveries in the field of exoplanet studies. In particular, it has made strides in the analysis of their atmospheres by studying light from the parent star as it travels through the gas surrounding the planets. JWST has recently bucked the trend and observed a some gas giant planets in the system HR 8799 and detected the presence of carbon dioxide in their atmospheres, suggesting there are similarities between the formation of this system and our own.
