Researchers conduct comprehensive review on preparation of MOF-based flame retardants via coordination bond cleavage

Since the first report of metal-organic framework (MOF)-based flame retardants in 2017, this research area has exploded. However, improving the flame-retardant efficiency of MOFs and expanding their application areas remain critical challenges. The physicochemical properties of MOFs are closely dependent on their topology, pore characteristics, and chemical composition, which can be modulated by...

Study finds anti-piracy messages backfire, especially for men

Threatening messages aimed to prevent digital piracy have the opposite effect if you're a man, a new study from the University of Portsmouth has found. According to the research, women tend to respond positively to this kind of messaging, but men typically increase their piracy behaviors by 18%.

More frequent extreme droughts result in significant crop losses, say researchers

Climate change has resulted in increasingly extreme weather events worldwide. NIBIO research scientist Pål Thorvaldsen is among the many scientists who participated in a large international drought experiment initiated by the University of Michigan, U.S. He explains that climate change may lead to more frequent occurrences of short-term extreme drought.

Physicists develop new solar cell design for better efficiency

Physicists at Paderborn University have used complex computer simulations to develop a new design for significantly more efficient solar cells than previously available. A thin layer of organic material, known as tetracene, is responsible for the increase in efficiency. The results have now been published in Physical Review Letters.

Proposed megafacility to breed monkeys in U.S. dismays activists and neighbors but excites scientists

Bainbridge, a rural town in southwestern Georgia with a population of 14,000, could soon become home to 30,000 additional residents: cynomolgus macaques. A new company called Safer Human Medicine (SHM) has announced plans to build an 80-hectare facility that would sell monkeys to universities, contract research organizations, and pharmaceutical companies that perform research on the...

Developing doubly sustainable quantum computers

In the future, the use of quantum computers could make a significant contribution to promoting greater sustainability in global developments. This was shown in a white paper, which was recently presented at the UN Climate Change Conference in Dubai and included contributions from the HPCQS consortium.

Artificial reefs help preserve coral reefs by shifting divers away from the natural ones, says study

Divers are essentially tourists who love coral reefs and invest a lot of time and effort in watching them. Unfortunately, divers also cause damage to corals, often unintentionally, by disturbing and resuspending sand, touching them, hitting them with their equipment, and scaring fish away. Artificial reefs have been proposed as a means of diverting diving pressure from the natural reef to...

Nature's checkup: Surveying biodiversity with environmental DNA sequencing

A thousand kilometers south of Tokyo, far into the largest ocean on Earth, lies a chain of small, volcanic islands—the Ogasawara Islands. Nature has been able to develop on its own terms here, far from both humans and the warm Kuroshio current, which acts like a shuttle, moving marine species from Taiwan, over the Ryukyu Islands, and up the Pacific coast of mainland Japan.

Examining a century of change in a New York City urban forest

There haven't been many long-term studies on urban forests, but data collected from the Thain Family Forest, which the New York Botanical Garden (NYBG) has been stewarding for more than a century, has provided an opportunity for scientists from The Forest School at YSE to study a century of changes of its composition.

Generating 'buzz' about new products can influence their success

The way companies announce new products or build up hype can often influence their success once those new products hit the market, according to new research from Binghamton University, State University of New York. Whether it's an upcoming blockbuster movie or a new rollout from major companies like Coca-Cola or Apple, the new research shows how companies might use this type of preannouncement...

Bat 'nightclubs' may be the key to solving the next pandemic

Bats carry some of the deadliest zoonotic diseases that can infect both humans and animals, such as Ebola and COVID-19. In a recently-published article in the journal Cell Genomics, a Texas A&M research team has revealed that some species of bats are protected against the viruses they carry because they commonly exchange immune genes during seasonal mating swarms.

Unlocking the energetic secrets of collective animal movement: How group behavior reduces energy costs in fish

Many animals, including apex predators, move in groups. We know this collective behavior is fundamental to the animal's ability to move in complex environments, but less is known about what drives the behavior because many factors underlie its evolution. Scientists wonder, though, if all these animals share a fundamental drive, such as for mating, safety, or perhaps even to save energy.
