Published Complex tree canopies help forests recover from moderate-severity disturbances



Extreme events wipe out entire forests, dramatically eliminating complex ecosystems as well as local communities. Researchers have become quite familiar with such attention-grabbing events over the years. They know less, however, about the more common moderate-severity disturbances, such as relatively small fires, ice storms, and outbreaks of pests or pathogens.
Published GPT-3 transforms chemical research



Scientists demonstrate how GPT-3 can transform chemical analysis, making it faster and more user-friendly.
Published Apex predators not a quick fix for restoring ecosystems



An experiment spanning more than two decades has found that removal of apex predators from an ecosystem can create lasting changes that are not reversed after they return -- at least, not for a very long time. The study challenges the commonly held belief that the reintroduction of wolves to Yellowstone National Park restored an ecosystem degraded by their absence.
Published One person can supervise 'swarm' of 100 unmanned autonomous vehicles



Research involving has shown that a 'swarm' of more than 100 autonomous ground and aerial robots can be supervised by one person without subjecting the individual to an undue workload.
Published Small but mighty -- study highlights the abundance and importance of the ocean's tiniest inhabitants



New research sheds light on tiny plankton, which measure less than 0.02mm in diameter but can make up more than 70% of the plankton biomass found in the ocean.
Published How food availability could catalyze cultural transmission in wild orangutans



The proverb "necessity is the mother of invention" has been used to describe the source from which our cultural evolution springs. After all, need in times of scarcity has forced humans to continually invent new technologies that have driven the remarkable cumulative culture of our species. But an invention only becomes cultural if it is learned and spread by many individuals. In other words, the invention must be socially transmitted. But what are the forces that drive social transmission?
Published Scammed! Animals 'led by the nose' to leave plants alone



Fake news works for wallabies and elephants. Herbivores can cause substantial damage to crops or endangered or protected plants, with traditional methods to deter foraging lethal, expensive or ineffective. Biologists are now using aromas from plants naturally repellent with remarkable success to deter the animals.
Published Discovery of a third RNA virus linage in extreme environments Jan 17, 2024



A research group has discovered a novel RNA viral genome from microbes inhabiting a high-temperature acidic hot spring. Their study shows that RNA viruses can live in high-temperature environments (70-80 degrees Celsius), where no RNA viruses have been observed before. In addition to the two known RNA virus kingdoms, a third kingdom may exist.
Published Engineers unveil new patch that can help people control robotic exoskeletons



A new patch uses tiny needles to measure electrical signals in the human body with incredible accuracy, even when these devices are stretched or twisted.
Published Artificial muscles -- lighter, safer, more robust



Researchers have developed artificial muscles that are lighter, safer and more robust than their predecessors. The newly developed actuators have a novel type of shell structure and use a high-permittivity ferroelectric material that can store relatively large amounts of electrical energy. They therefore work with relatively low electrical voltage, are waterproof, more robust and safer to touch.
Published Sweat-resistant wearable robot sensor



A joint research team has developed a stretchable and adhesive microneedle sensor that can be attached to the skin and stably measure high-quality electrophysiological signals for a long period of time.
Published New research shows how pollutants from aerosols and river run-off are changing the marine phosphorus cycle in coastal seas



New research sheds light on how pollutants from aerosols and river run-off are impacting coastal seas. The research identified an 'Anthropogenic Nitrogen Pump' which changes the phosphorus cycle and therefore likely coastal biodiversity and associated ecosystem services.
Published Researchers propose AI-guided system for robotic inspection of buildings, roads and bridges



Our built environment is aging and failing faster than we can maintain it. Recent building collapses and structural failures of roads and bridges are indicators of a problem that's likely to get worse, according to experts, because it's just not possible to inspect every crack, creak and crumble to parse dangerous signs of failure from normal wear and tear. In hopes of playing catch-up, researchers are trying to give robotic assistants the tools to help inspectors with the job.
Published Rising sea levels could lead to more methane emitted from wetlands



A Bay Area wetlands ecosystem that was expected to serve as a carbon sink is emitting surprisingly high levels of methane, a potent greenhouse gas. The study suggests factors governing carbon cycles in these habitats are even more complex than we thought.
Published Robot trained to read braille at twice the speed of humans



Researchers have developed a robotic sensor that incorporates artificial intelligence techniques to read braille at speeds roughly double that of most human readers.
Published Utilizing active microparticles for artificial intelligence



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.
Published How waves and mixing drive coastal upwelling systems



Large coastal upwelling systems along the eastern margins of the Atlantic and Pacific Oceans are among the most biologically productive and biodiverse regions of the world's oceans. Typically, the strength and timing of upwelling in such systems are linked to the prevailing winds. Interestingly, in some tropical regions, high levels of productivity occur even when the upwelling favorable winds are weak.
Published Scientists design a two-legged robot powered by muscle tissue



Compared to robots, human bodies are flexible, capable of fine movements, and can convert energy efficiently into movement. Drawing inspiration from human gait, researchers from Japan crafted a two-legged biohybrid robot by combining muscle tissues and artificial materials. This method allows the robot to walk and pivot.
Published Autonomous synthesis robot uses AI to speed up chemical discovery



Chemists have developed an autonomous chemical synthesis robot with an integrated AI-driven machine learning unit. Dubbed 'RoboChem', the benchtop device can outperform a human chemist in terms of speed and accuracy while also displaying a high level of ingenuity. As the first of its kind, it could significantly accelerate chemical discovery of molecules for pharmaceutical and many other applications.
Published Diverse forests are best at standing up to storms



European forests with a greater diversity of tree species are more resilient to storms, according to new research.
