Innovation promises to prevent power pole-top fires      (via sciencedaily.com)     Original source 

Engineers in Australia have found a new way to make power-pole insulators resistant to fire and electrical sparking, promising to prevent dangerous pole-top fires and reduce blackouts. Pole-top fires pose significant challenges to power providers and communities worldwide. In March, pole-top fires cut power from 40,000 homes and businesses in Perth, Australia. The 2020 Royal Commission into National Natural Disaster Arrangements found that power outages experienced by 280,000 customers from various energy providers during Black Summer fires in Australia were mainly triggered by events involving insulators and poles.

Fading lights: Multiple threats to North America's firefly populations      (via sciencedaily.com)     Original source 

Scientists have applied a data-driven approach to understanding firefly population dynamics on a continental scale. Key findings from this new study indicate that fireflies, part of the beetle order, are sensitive to various environmental factors, from short-term weather conditions to longer climatic trends, including the number of growing-degree days related to temperature accumulations.

Long snouts protect foxes when diving headfirst in snow      (via sciencedaily.com)     Original source 

When hunting for mice in winter, red and arctic fox are known to plunge headfirst at speeds of 2-4 meters per second, but their sharp noses reduce the impact force in snow and protect them from injury, according to a new study.

Physicists show that light can generate electricity even in translucent materials      (via sciencedaily.com)     Original source 

Some materials are transparent to light of a certain frequency. When such light is shone on them, electrical currents can still be generated, contrary to previous assumptions. Scientists have managed to prove this.

Fixin' to be flexitarian: Scrap fish and invasive species can liven up vegetables      (via sciencedaily.com)     Original source 

Greening the way we eat needn't mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to 'boring' vegetables. A gastrophysicist puts mathematical equations to work in calculating the umami potential of everything from seaweed and shrimp paste to mussels and mackerel.

Test reveals mice think like babies      (via sciencedaily.com)     Original source 

Are mice clever enough to be strategic? A neuroscientist who studies learning in humans and animals, and who has long worked with mice, wondered why rodents often performed poorly in tests when they knew how to perform well. With a simple experiment, and by acting as 'a little bit of a mouse psychologist,' he and his team figured it out.

Could fishponds help with Hawaii's food sustainability?      (via sciencedaily.com)     Original source 

Indigenous aquaculture systems in Hawaii, known as loko i'a or fishponds, can increase the amount of fish and fisheries harvested both inside and outside of the pond. Today, aquaculture supplies less than 1% of Hawaii's 70 million pounds of locally available seafood, but revitalization of loko i'a has the potential to significantly increase locally available seafood.

Robotic nerve 'cuffs' could help treat a range of neurological conditions      (via sciencedaily.com)     Original source 

Researchers have developed tiny, flexible devices that can wrap around individual nerve fibers without damaging them. The researchers combined flexible electronics and soft robotics techniques to develop the devices, which could be used for the diagnosis and treatment of a range of disorders, including epilepsy and chronic pain, or the control of prosthetic limbs.

How electric vehicle drivers can escape range anxiety      (via sciencedaily.com)     Original source 

Two of the biggest challenges faced by new and potential electric vehicle (EV) drivers are range anxiety and speed of charging, but these shouldn't have to be challenges at all. Researchers discovered that a change in refueling mindset, rather than improving the size or performance of the battery, could be the answer to these concerns.

Unveiling the lionfish invasion in the Mediterranean Sea      (via sciencedaily.com)     Original source 

Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.
