Researchers have captured what they believe is the first ever video of a shark or any large marine animal being struck by a boat.

A prototype device harvests drinking water from the atmosphere, even in arid places.

Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.

Faced with the world's impending freshwater scarcity, researchers turned to solar steam generators, which are emerging as a promising device for seawater desalination. The team sought design inspiration from trees and harnessed the potential of 3D printing. They present technology for producing efficient SSGs for desalination and introduces a novel method for printing functional nanocomposites for multi-jet fusion. Their SSGs were inspired by plant transpiration and are composed of miniature tree-shaped microstructures, forming an efficient, heat-distributing forest.

Aluminum scandium nitride thin films could pave the way for the next generation of ferroelectric memory devices, according to a new study. Compared to existing ferroelectric materials, these films maintain their ferroelectric properties and crystal structure even after heat treatment at temperatures up to 600 C in both hydrogen and argon atmospheres. This high stability makes them ideal for high-temperature manufacturing processes under the H2-included atmosphere used in fabricating advanced memory devices.

An international team of researchers has embedded gold nanorods in hydrogels that can be processed through 3D printing to create structures that contract when exposed to light -- and expand again when the light is removed. Because this expansion and contraction can be performed repeatedly, the 3D-printed structures can serve as remotely controlled actuators.

Some species of fish can evolve their egg-laying habits in response to predators in the area in order to survive, according to new research.

People's moral values could limit their uptake of lab-grown meat, a study suggests. People who say living a natural life is morally important to them are more likely to reject lab-grown meat -- also known as cultured or cultivated meat -- than those who do not, research shows.

A pioneering study has unveiled the first paired observations of sexual behavior and vocalizations in wild leopard seals. The study on the mysterious leopard seal represents a major advance in understanding the behavior of one of the most difficult apex predators to study on Earth.

Cut marks on fossils could be evidence of humans exploiting large mammals in Argentina more than 20,000 years ago, according to a new study.

The most threatened reef fishes are also the most overlooked by scientists and the general public. Scientists measured the level of human interest in 2,408 species of marine reef fish and found that the attention of the scientific community is attracted by the commercial value more than the ecological value of the fishes. The public, on the other hand, is primarily influenced by the aesthetic characteristics of certain species, such as the red lionfish (Pterois volitans) and the mandarinfish (Synchiropus splendidus).

Researchers engineered a new technique to identify at the nanoscale level what components are overheating in electronics and causing their performance to fail.

Researchers have analysed data from 127 studies to reveal 'thresholds' for when logged rainforests lose the ability to sustain themselves. The results could widen the scope of which forests are considered 'worth' conserving, but also show how much logging degrades forests beyond the point of no return.

Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers have now discovered that certain human flu viruses and avian flu viruses can also use a second entry pathway, a protein complex of the immune system, to infect cells. This ability helps the viruses infect different species -- and potentially jump between animals and humans.

Industrialized farming is often thought to reduce the risk of zoonotic diseases because of better control, biosecurity and separation of livestock. A new study examines the effect of social and economic factors -- which are often overlooked in traditional assessments.

Carbon capture is a promising approach for mitigating carbon dioxide (CO2) emissions. Different materials have been used to capture CO2 from industrial exhaust gases. Scientists developed hybrid CO2 capture materials containing sodium carbonate and nanocarbon prepared at different temperatures, tested their performance, and identified the optimal calcination temperature condition. They found that the hybrid material exhibits and maintains high CO2 capture capacity for multiple regeneration cycles at a lower temperature, making it cost- and energy-effective.

Although there is a large body of research on pests evolving tolerances for the pesticides meant to destroy them, there have been considerably fewer studies on how non-target animals in these ecosystems may do the same.

A study helps explain why dairy cows infected by highly pathogenic avian influenza are shedding the virus in their milk. Their findings could help develop biosecurity measures aimed at slowing the spread of the illness.

An invasive fungus that colonizes the skin of hibernating bats with deadly consequences is a stealthy invader that uses multiple strategies to slip into the small mammals' skin cells and quietly manipulate them to aid its own survival. The fungus, which causes the disease white-nose syndrome, has devastated several North American species over the last 18 years.
