Nanocapsules enable cell-inspired metabolic reactions

Scientists at the University of Basel created bio-catalytic capsules capable of producing glucose-6-phosphate, a key metabolite involved in carbohydrate degradation and energy storage. The nanocapsules, measuring less than 200 nanometers, can be taken up by cells and may pave the way for new disease treatments.

PET imaging tracks Zika virus infection, disease progression in mouse model

Researchers used PET imaging to study brain inflammation following Zika virus infection in mice, finding a 2- to 6-fold increase in global brain neuroinflammation over time. The technology allows for longitudinal studies of the same animal during the course of the infection, providing enhanced information about disease progression.

Wait-and-see strategy pays off, incentives needed for risk takers

A recent study by University of Illinois economist Hope Michelson found that wait-and-see strategies among farmers in Nicaragua can lead to increased participation in supply chains. The study suggests that incentives may be necessary to encourage risk-takers to join the market, as early adopters bear initial costs and benefits.

Colder and colder

Researchers at the Weizmann Institute of Science have created a novel method for cooling ions using electrostatic fields, allowing them to reach temperatures near absolute zero. This breakthrough enables the study of large biological molecules and nanoparticles, with potential applications in medicine and materials science.

American oaks share a common northern ancestor

Researchers have solved the mystery of the geographic origins of American oaks by finding that red and white oaks diverged simultaneously from a single species 45 million years ago. This common ancestor gave rise to two distinct lineages, which then radiated into different ecological spaces across North America.

Color naming across languages

Researchers analyzed color-naming data from 110 languages and found that warm colors like red, yellow, and orange are generally easier to communicate than cool colors like blue and green. The study suggests that differences in color categorization may reflect cultural differences in color usefulness.

Dogs' social skills linked to oxytocin sensitivity

A new study from Linköping University finds that dogs' willingness to collaborate with humans is linked to genetic variations in the oxytocin receptor gene. The researchers discovered a possible explanation for why dogs differ in their ability to work together, which may have contributed to human selection during domestication.
