By analyzing decades of war death statistics, researchers found large civil wars tend to cool off over time, but wars between nations show a persistent risk of ratcheting up in size. 

University of Georgia researchers developed a new high-resolution light-sheet imaging system that is fast enough to document seizures in 3D in real-time.

The study was conducted by researchers from Southwest Petroleum University, Tongwei Solar (Chengdu) Ltd., the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, and collaborating institutions in China. Published (DOI: 10.1016/j.esen.2026.100065) online on May 9, 2026, in eScience Energy, the research evaluated 2T perovskite/silicon tandem solar cells under globally varying spectral conditions and developed a practical framework to assess outdoor spectral mismatch, annual energy yield, and the levelized cost of electricity (LCOE) across representative PV deployment climates and operating environments worldwide.

A team led by Wuhan University of Technology, with collaborators from Xi'an Jiaotong University, published (DOI: 10.1016/j.esen.2026.100070) the study online on May 20, 2026, in eScience Energy. The researchers investigated how c-axis dimension tailoring affects stress evolution in layered P2-type Na_0.75Ni_0.25Mn_0.75O₂ cathodes, showing that thinner grains can reduce strain build-up, improve stress dissipation, prevent internal cracking, and extend sodium-ion battery cycling stability.

Shoppers who use trolleys embedded with digital screens to assist trips to the supermarket spend up to a third more than those who do not, according to new research by Bayes Business School (City St George’s, University of London).
