Light pollution drives increased risk of West Nile virus

Florida has experienced a relatively mild winter, which typically translates to more mosquitoes in the summer and more birds on which they can feast. If history repeats itself, it's likely there will be an uptick in West Nile virus cases this year, especially in the outer fringes of the suburbs where much of the nighttime illumination emanates from the skyglow of nearby cities.

Neglected species: 'Living fossil' sturgeon on the brink of extinction

Depending on your political affiliation, the words "Sturgeon in peril" may fill you with delight, despair or indifference. For those of us at Fauna & Flora International (FFI), however, this kind of headline is already old news.

Stranded endangered false killer whale divulges a dietary first

Researchers found something unexpected inside a rare false killer whale that stranded dead on Maui in February 2021, and it could ultimately help the endangered species. The whale was an insular false killer whale, the most critically endangered species of dolphins and whales in Hawaiian waters. While investigating it's cause of death, the University of Hawaiʻi Marine Mammal Health and Stranding Lab found the remains of octopuses in its stomach, which was previously an unknown part of the species' diet.

Scientists study potential volcanic impacts on future global land monsoon precipitation changes

Scientists have found global precipitation significantly decreased in the year following large volcanic eruptions, as evidenced by paleoclimate reconstructions and historical observations. Decreased precipitation is a robust post-volcano eruption signal in the monsoon climate, and scientists want to explore volcanos' roles in future climate. However, major volcanic eruptions are generally not included in current model projection scenarios because they are inherently unpredictable events.

Research reveals mechanism of salinity tolerance in Italian ryegrass

Italian ryegrass (Lolium multiflorum) is a widely cultivated forage with excellent quality, high yield, good palatability and rich nutritional value. However, its growth is inhibited by salt tress, which is a major growth limiting factor.

Landsat satellite data warns of harmful algal blooms

Come summer, Utahns will flock to the state's lakes and reservoirs to boat, swim and picnic along the shore. And every week, if not every day, scientists like Kate Fickas of Utah State University in Logan will use satellite images and other data to monitor recreation sites to check for rapid growth of algae into a bloom, and make sure the water is safe for people and pets.

Keeping track of spacecraft as Earth's water alters its spin

Mass is constantly being redistributed around our planet, as Earth's atmosphere, oceans and other bodies of water on and under the surface melt, shift and stir. This mass redistribution alters Earth's center of gravity, which in turn speeds up and slows down the planet's spin—and so the length of the day—as well as changing the orientation of its spin axis. These changes to Earth's spin and orientation occur over relatively short timescales of days and weeks, and threaten communication between ground stations and missions in orbit and across the solar system.

Nanobiomaterial boosts neuronal growth in mice with spinal cord injuries

Researchers from the Department of Orthopedics of Tongji Hospital at Tongji University in Shanghai have successfully used a nanobiomaterial called layered double hydroxide (LDH) to inhibit the inflammatory environment surrounding spinal cord injuries in mice, accelerating regeneration of neurons and reconstruction of the neural circuit in the spine. The researchers were also able to identify the underlying genetic mechanism by which LDH works. This understanding should allow further modification of the therapy which, in combination with other elements, could finally produce a comprehensive, clinically applicable system for spinal cord injury relief in humans.

Algorithms inspired by social networks reveal lifecycle of substorms, a key element of space weather

Space weather often manifests as substorms, where a beautiful auroral display such as the Northern Lights is accompanied by an electrical current in space which has effects at earth that can interfere with and damage power distribution and electrical systems. Now, the lifecycle of these auroral substorms has been revealed using social media-inspired mathematical tools to analyse space weather observations across the Earth's surface.
