Healthy plant-based diets better for the environment than less healthy plant-based diets
Healthier plant-based dietary patterns were associated with better environmental health, while less healthy plant-based dietary patterns, which are higher in foods like refined grains and sugar-sweetened beverages, required more cropland and fertilizer…
Thirsty wheat needed new water management strategy in ancient China
Research shows that a practice of purposeful water management, or irrigation, was adopted in northern China about 4,000 years ago as part of an effort to grow new grains that had been introduced from southwest Asia. But the story gets more complex from…
Chronic jet lag discovered in people living with HIV
People living with HIV have a significantly delayed internal body clock, consistent with the symptoms of jet lag, according to new findings.
A dual boost for optical delay scanning
Various applications of pulsed laser sources rely on the ability to produce a series of pulse pairs with a stepwise increasing delay between them. Implementing such optical delay scanning with high precision is demanding, in particular for long delays….
A supernova in distant space allows us to understand the origin of the elements in the universe
A supernova is a stellar explosion, which occurs when the lives of some really massive stars come to an end. In this violent epilogue, the star expels the material from its outer layers by means of a shock wave, allowing us to see the various elements …
Nanotechnology platform enables immune conversion of cancer cells, sensitizing them to immunotherapy
A team of researchers has developed a nanotechnology platform that can change the way the immune system sees solid tumor cells, making them more receptive to immunotherapy. The preclinical findings suggest this adaptable immune conversion approach has …
New technology creates carbon neutral chemicals out of thin air
It is possible to capture carbon dioxide (CO2) from the surrounding atmosphere and repurpose it into useful chemicals usually made from fossil fuels, according to a new study.
Why older people are more susceptible to the flu
An inflammatory lipid appears to reduce the number of macrophages inside the lungs with age.
Picking the fastest progressing patients to speed Parkinson’s disease clinical trials
A team has developed a new tool that can predict how Parkinson’s disease patients will fare over the course of a year based on their genetics, brain scans and physical examinations.
Experimental cancer vaccine shows promise in animal studies
An experimental therapeutic cancer vaccine induced two distinct and desirable immune system responses that led to significant tumor regression in mice, report investigators.
