Mangroves and saltmarshes sequester large amounts of carbon, mitigating the greenhouse effect. New research shows that these environments are perhaps twice as effective as previously thought.

Computer scientists found that email notifications to update passwords potentially yielded diminishing returns after three messages. They also found that a prompt to update passwords while users were trying to log in was effective for those who had ignored email reminders. Researchers also found that users whose jobs didn't require much computer use struggled the most with the update.

Scientists have developed a new approach to machine learning -- a form of artificial intelligence -- to identify drugs that help minimize harmful scarring after a heart attack or other injuries.

Engineers have demonstrated a system they've dubbed 'MadRadar' for fooling automotive radar sensors into believing almost anything is possible. The technology can hide the approach of an existing car, create a phantom car where none exists or even trick the radar into thinking a real car has quickly deviated from its actual course. And it can achieve this feat in the blink of an eye without having any prior knowledge about the specific settings of the victim's radar, making it the most troublesome threat to radar security to date.

Floating macroalgal acts as a raft that provides habitat for a diverse array of juvenile oceanic fish a new study has found. The study conducted in the Ningaloo Coast World Heritage Area, Western Australia, revealed that fish were more abundant around macroalgal rafts than in open water, with eleven species of juvenile fishes associated with Sargassum rafts, and one species of both juveniles and adults.

As sea otters recolonize a California estuary, they are restoring its degraded geology by keeping populations of overgrazing marsh crabs in check, a new study shows. The crabs' appetite for plant roots, and their tunneling behavior had caused many of the estuary's marshes and creekbanks to erode and collapse in the otters' absence. Today, erosion has slowed by up to 90% in areas with large otter populations and marshes and streambeds are restabilizing.

To find poison ivy before it finds you, scientists have published a new study in which they show how they used artificial intelligence to confirm that an app can identify poison ivy. The app is not yet commercially available, nor is there a timetable for it to be available.

An international team has developed a new method to make and manipulate a widely studied class of high-temperature superconductors. This technique should pave the way for the creation of unusual forms of superconductivity in previously unattainable materials.

Scientists have developed a green antibiotic alternative to treat the deadly pathogen Streptococcus iniae in hybrid striped bass, the fourth most farmed finfish in the United States, according to a recent study.

New research finds that individual behavioural flexibility and not evolutionary selection is driving the northward shift of Balearic shearwaters. The findings were revealed through a decade-long study which tagged individual birds. The results indicate that individual animals may have greater behavioural flexibility to respond to climate change impacts than previously thought.

Artificial intelligence using neural networks performs calculations digitally with the help of microelectronic chips. Physicists have now created a type of neural network that works not with electricity but with so-called active colloidal particles.The researchers describe how these microparticles can be used as a physical system for artificial intelligence and the prediction of time series.

An interdisciplinary team of researchers has developed a soft implantable device with dozens of sensors that can record single-neuron activity in the brain stably for months.

Seagrasses provide the foundation of one of the most highly biodiverse, yet vulnerable, coastal marine ecosystems globally. They arose in three independent lineages from their freshwater ancestors some 100 million years ago and are the only fully submerged, marine flowering plants. Moving to such a radically different environment is a rare evolutionary event and definitely not easy. How did they do it? New reference quality genomes provide important clues with relevance to their conservation and biotechnological application.

People who were more skeptical of human-caused climate change or the Black Lives Matter movement who took part in conversation with a popular AI chatbot were disappointed with the experience but left the conversation more supportive of the scientific consensus on climate change or BLM. This is according to researchers studying how these chatbots handle interactions from people with different cultural backgrounds.

Model predictions showed a rapid increase in microplastic accumulation and contamination across the penguins' prey organisms resulting in Galapagos penguin showing the highest level of microplastics per biomass, followed by barracuda, anchovy, sardine, herring, and predatory zooplankton.

New research revealed a daily pattern wherein humpback whales move their singing away from shore throughout the day and return to the nearshore in the evening.
