Insulin can increase mosquitoes’ immunity to West Nile virus

A discovery has the potential to inhibit the spread of West Nile virus as well as Zika and dengue viruses. The researchers demonstrated that mammalian insulin activated an antiviral immunity pathway in mosquitoes, increasing the insects’ ability to suppress the viruses. Since mosquito bites are the most common way humans are infected with West Nile, stopping the virus among the insects would protect human health.

System by which plants have formed secondary buds since ancient times illuminated

A collaborative research group has succeeded in identifying an important transcription factor, GCAM1, which allows liverwort plants to asexually reproduce through creating clonal progenies (vegetative reproduction). Furthermore, this transcription factor was revealed to have the same origin as those which regulate secondary bud formation in angiosperms. It is hoped that these discoveries will lead to the development of technologies to increase the cultivation rate of a variety of plants in agriculture and horticulture.

Europe’s lax speed limits once appeared irrevocable. Global warming and pollution are changing that. – Washington Post

Rutte was widely considered to be a pro-motorist leader. But in May, the country’s top court ruled that the Netherlands was violating European Union law and needed to drastically curb nitrogen pollution and nitrogen oxide emissions — a source of…

How to take care of newborn puppies

If you have newborn puppies either in your home or on the way, you’re likely “nesting,” getting ready for the tiny, squeaking balls of fur. Where will they sleep? How often will they eat? Will they need blankets? How will…

Visualizing heat flow in bamboo could help design more energy-efficient and fire-safe buildings

Modified natural materials will be an essential component of a sustainable future, but first a detailed understanding of their properties is needed. The way heat flows across bamboo cell walls has been mapped using advanced scanning thermal microscopy, providing a new understanding of how variations in thermal conductivity are linked to the bamboo’s elegant structure. The findings will guide the development of more energy-efficient and fire-safe buildings, made from natural materials, in the future.

Hubble captures a dozen galaxy doppelgangers

The distant galaxy in this image is nicknamed the Sunburst Arc. It’s been lensed into multiple images by a massive, intervening galaxy cluster. A recent study revealed that the 4 bright arcs in this Hubble image contain 12 images – cosmic doppelgangers – of this very distant galaxy.

Astronomers catch a record-setting X-ray burst

The sudden spike of X-rays released as much energy in 20 seconds as our sun does in nearly 10 days. Turns out it was a massive thermonuclear flash on a pulsar, the crushed remains of a star that exploded as a supernova long ago.
