Researchers take 'significant leap forward' with quantum simulation of molecular electron transfer

Researchers have made a meaningful advance in the simulation of molecular electron transfer -- a fundamental process underpinning countless physical, chemical and biological processes. The study details the use of a trapped-ion quantum simulator to model electron transfer dynamics with unprecedented tunability, unlocking new opportunities for scientific exploration in fields ranging from molecular electronics to photosynthesis.

Researchers discover replication hubs for human norovirus

Combining bioinformatics and experimetal approaches, researchers have discovered replication hubs for human norovirus, the leading cause of viral gastroenteritis accounting for an estimated 685 million cases and approximately 212,000 deaths globally per year. The findings could lead to designing antiviral drugs to prevent, control or treat these serious infections.

Paving the way for the future of energy storage with solid-state batteries

Advances in solid-state battery research are paving the way for safer, longer-lasting energy storage solutions. A recent review highlights breakthroughs in inorganic solid electrolytes and their role in improving battery performance. The study also addresses key challenges, such as interfacial compatibility, while proposing innovative strategies for next-generation battery technologies.

Dark energy 'doesn't exist' so can't be pushing 'lumpy' Universe apart

One of the biggest mysteries in science -- dark energy -- doesn't actually exist, according to researchers looking to solve the riddle of how the Universe is expanding. For the past 100 years, physicists have generally assumed that the cosmos is growing equally in all directions. They employed the concept of dark energy as a placeholder to explain unknown physics they couldn't understand, but the contentious theory has always had its problems. Now a team of physicists and astronomers are challenging the status quo, using improved analysis of supernovae light curves to show that the Universe is expanding in a more varied, 'lumpier' way.

Poor vascular health accelerates brain aging

Using an AI tool, researchers have analyzed brain images from 70-year-olds and estimated their brains' biological age. They found that factors detrimental to vascular health, such as inflammation and high glucose levels, are associated with an older-looking brain, while healthy lifestyles were linked to brains with a younger appearance.

Dripstones offer insights into climate dynamics in Europe

Investigations into precipitation patterns in eastern Central Europe since the end of the last ice age have shown that dynamic processes in atmospheric circulation, such as the North Atlantic jet stream, influence regional changes in precipitation. The researchers analyzed dripstones from caves in Romania, which act as a natural climate archive that allows conclusions to be drawn about precipitation variability over a period of approximately 20,000 years.
