A new look at color displays

Researchers have developed a method that may lead to new types of displays based on structural colors. The discovery opens the way to cheap and energy-efficient color displays and electronic labels.

Predicting the future of cod

Until now, fisheries have set catch levels a year in advance. Long-term influences such as changes in water temperatures are not taken into account. Researchers have now developed a computational model that can estimate the future of cod a full ten years in advance - taking into both account fishing and climate. The fishing industry has a completely new planning tool at its disposal.

Fighting COVID with COVID

Researchers design a new COVID-19 therapy that uses a defective version of the SARS-CoV-2 virus to drive the disease-causing version to extinction.

Keeping bacteria under lock and key

A chemical and biomolecular engineer with biosecurity expertise in teaching cells to create and harness chemical building blocks not found in nature. New research describes progress on the stability of a biocontainment strategy that uses a microbe's dependence on a synthetic nutrient to keep it contained.

Ultrathin semiconductors electrically connected to superconductors

Researchers have equipped an ultrathin semiconductor with superconducting contacts. These extremely thin materials with novel electronic and optical properties could pave the way for previously unimagined applications. Combined with superconductors, they are expected to give rise to new quantum phenomena and find use in quantum technology.

Lab analysis finds near-meat and meat not nutritionally equivalent

A research team's deeper examination of the nutritional content of plant-based meat alternatives, using metabolomics, shows they're as different as plants and animals. Beef contained 22 metabolites that the plant substitute did not. The plant-based substitute contained 31 metabolites that meat did not. The greatest distinctions occurred in amino acids, dipeptides, vitamins, phenols, and types of...

Source of remarkable memory of 'superagers' revealed

'Superagers' who performed a challenging memory task in an MRI scanner were able to learn and recall new information as well as 25-year-old participants. Neurons in the visual cortex of brains of superaging older adults retain their selective and efficient ability to process visual stimuli and create a distinct memory of the images. In the future, interventions to train specific areas of the brain...

Bacterial survival kit to endure in soil

Soil bacteria have amazing strategies to attain energy in order to withstand stressful times. Researchers investigated how acidobacteria, which are widespread in soils, can survive under adverse conditions.

New nanotech will enable a 'healthy' electric current production inside the human body, researchers report

Researchers have developed an innovative material that is eco-friendly, completely biological and non-toxic, and causes no harm to the body's tissues. The material is as strong as titanium and extremely flexible. The new development will allow for the charging of pacemakers using only the heartbeat, eliminating the need for batteries. The new material will make it possible to produce green energy...

The evolution of vinegar flies is based on the variation of male sex pheromones

By analyzing the genomes of 99 species of vinegar flies and evaluating their chemical odor profiles and sexual behaviors, researchers show that sex pheromones and the corresponding olfactory channels in the insect brain evolve rapidly and independently. The new study is a valuable basis for understanding how pheromone production, their perception and processing in the brain, and ultimately the...

New species of pseudo-horses living 37 million years ago

Scientists have described two new species of palaeotheriidae mammals that inhabited the subtropical landscape of Zambrana (Álava) about 37 million years ago. Their atypical dental features could point to a difference in environmental conditions between the Iberian and Central European areas.

Making computer servers worldwide more climate friendly

An elegant new algorithm can significantly reduce the resource consumption of the world's computer servers. Computer servers are as taxing on the climate as global air traffic combined, thereby making the green transition in IT an urgent matter. The researchers expect major IT companies to deploy the algorithm immediately.
