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

21 December 2024 at 00:10
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.

Breakthrough new material brings affordable, sustainable future within grasp

21 December 2024 at 00:10
Researchers have developed a new material for sodium-ion batteries, sodium vanadium phosphate, that delivers higher voltage and greater energy capacity than previous sodium-based materials. This breakthrough could make sodium-ion batteries a more efficient and affordable alternative to lithium-ion, using a more abundant and cost-effective resource.

Researchers discover replication hubs for human norovirus

20 December 2024 at 20:35
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

20 December 2024 at 18:32
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.

A tropical disease in Switzerland: Call for coordinated action on Chagas disease

20 December 2024 at 18:30
Researchers conducted a comprehensive review of Chagas disease in Switzerland. Although typically found in Latin America, Chagas disease affects between 2,000 and 4,000 people in Switzerland. The review underscores the need for improved screening and healthcare strategies to eliminate Chagas disease in Switzerland.

Water and gruel -- not bread: Discovering the diet of early Neolithic farmers in Scandinavia

20 December 2024 at 18:30
At a Neolithic settlement on the Danish island Funen dating back 5,500 years, archaeologists have discovered both grinding stones and grains from early cereals. However, new research reveals that the inhabitants did not use the stones to grind the cereal grains. Instead of making bread, they likely prepared porridge or gruel from the grains.

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

20 December 2024 at 18:30
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

20 December 2024 at 18:29
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

20 December 2024 at 18:28
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.
