POSTECH, Samsung SDI, Northwestern University, and Chung-Ang University improved the battery durability and energy density with nano spring coating.

Coinciding with International School Meals Day (13 March), a new case study from one of Nairobi’s largest informal settlements shows that introducing biodiversity - including often overlooked indigenous foods - into school lunches can offer benefits both for nutrition and cost-saving.

A new analysis reveals complex linkages among the United Nations’ (UN’s) 17 Sustainable Development Goals—which include such objectives as gender equality and quality education—and finds that no country is on track to meet all 17 goals by the target year of 2030. Alberto García-Rodríguez of Universidad Nacional Autónoma de México and colleagues present these findings in the open-access journal PLOS One on March 12, 2025.

Experimentalist governance, which learns from practice itself, and valuing local communities and traditional knowledge are the strengths of the project, which reconciles environmental conservation with job creation and income generation.

Miniaturized pumps and valves that rely on the motion of dielectric elastomeric silicone films are being created in Saarland, Germany. Not only are these devices lightweight, compact and energy-efficient, but they also work without the need for compressed air, motors or lubricants. They are cleanroom-compatible and can be continuously controlled while operating. The research team led by Professors Stefan Seelecke and Paul Motzki from Saarland University will be exhibiting a prototype film-based vacuum pump at this year’s Hannover Messe from 31 March to 4 April. Their lightweight, low-energy technology is able to pull a vacuum down to 300 millibars of pressure (30% of standard atmospheric pressure). Saarland Innovation Stand, Hall 2, Stand B10
