Researchers demonstrate the contribution of climate change to the spatial expansion of West Nile virus in Europe, a virus that constitutes a new public health threat in the continent. Their findings highlight a notable increase in the area ecologically suitable for the virus circulation since the beginning of last century and an increase in the human population at risk of exposure, due in part to climate change.

While pesticides protect crops from hungry animals, pesky insects, or even microbial infections, they also impact other vital organisms, including bees and earthworms. And today, research reveals that worms are affected by the relatively small amounts of chemicals that can leach out of pesticide-treated seeds. Exposure to nonlethal amounts of these insecticides and fungicides resulted in poor weight gain and mitochondrial DNA (mtDNA) damage in the worms.

From lab-grown chicken to cricket-derived protein, these innovative alternatives offer hope for a planet struggling with the environmental and ethical impacts of industrial agriculture. Now, scientists add a new recipe to the list -- cultured beef rice -- by growing animal muscle and fat cells inside rice grains. The method results in a nutritious and flavorful hybrid food that, once commercialized, could offer a more affordable protein alternative with a smaller carbon footprint.

Researchers have succeeded in biomanufacturing from chemically synthesized sugar for the first time in the world. With refinement of this technology, one can envision a future society in which the sugar required for biomanufacturing can be obtained 'anytime, anywhere, and at high rate'. In the future, biomanufacturing using chemically synthesized sugar is expected to be a game changer in the biotechnology field -- including the production of biochemicals, biofuels, and food, where sugar is an essential raw material -- ultimately leading to the creation of a new bio-industry.

Researchers have unveiled a groundbreaking discovery shedding light on the intricate play between legume plants and nitrogen-fixing bacteria. Their study details the crucial role played by phosphorylation in driving the formation of symbiotic organs, known as nodules, on plant roots. The long-term goal is to enable symbiosis in root nodules in important crops such as barley, maize and rice to avoid the use of chemical fertilizers.

Astronomers have uncovered evidence of how the enigmatic gap in the size distribution of exoplanets at around two Earth radii emerges. Their computer simulations demonstrate that the migration of icy, so-called sub-Neptunes into the inner regions of their planetary systems could account for this phenomenon. As they draw closer to the central star, evaporating water ice forms an atmosphere that makes the planets appear larger than in their frozen state. Simultaneously, smaller rocky planets gradually lose a portion of their original gaseous envelope, causing their measured radius to shrink over time.

Researchers report the results of the first ever genome-wide association study (GWAS) of a biosafety level 4 (BSL-4) virus. The team found two key human genetic factors that could help explain why some people develop severe Lassa fever, and a set of LARGE1 variants linked to a reduced chance of getting Lassa fever. The work could lay the foundation for better treatments for Lassa fever and other similar diseases. The scientists are already working on a similar genetics study of Ebola susceptibility.

Researchers have shed new light on the ancient relationship between moss and fungi. They discovered that intricate moss-fungi interactions often depended on a third variable -- the presence of endobacteria within the fungi themselves.
