This month, a group of stroke survivors in British Columbia will test a new technology designed to aid their recovery, and ultimately restore use of their limbs and hands. Participants will wear a new groundbreaking 'smart glove' capable of tracking their hand and finger movements during rehabilitation exercises.

'Soft robots,' medical devices and implants, and next-generation drug delivery methods could soon be guided with magnetism -- thanks to a metal-free magnetic gel developed by researchers. Carbon-based, magnetic molecules are chemically bonded to the molecular network of a gel, creating a flexible, long-lived magnet for soft robotics.

Research has determined key factors that impact biodiversity among spiders and insects in urban areas. The response of specific groups varied significantly, surprising the researchers. The study findings can help urban planners, landscapers, builders and homeowners make choices that increase biodiversity. Dozens of species previously unknown to science came to light through the study.

Some invasive plants can form persistent banks of seeds that remain under the soil for years, and this makes their eradication practically impossible. Over time, this invisible population of large quantities of living, buried plants -- in seed form -- will reoccupy ecosystems and displace the typical flora of the natural environment.

Beaches and dunes globally squeezed by roads and buildings. Beaches and dunes are becoming increasingly trapped between rising sea levels and infrastructure. Researchers found that today, when dropped on a random beach anywhere in the world, you only need to walk 390 meters (on average) to find the nearest road or building. And while that short walking distance may seem convenient if you want a day at the beach, it's bad news for our protection against rising sea levels, drinking water supplies and biodiversity.

Research using thermal imaging of numbats in Western Australia has found that during hot weather the endangered animals are limited to as little as ten minutes of activity in the sun before they overheat to a body temperature of greater than 40 C.

Scientists developed a soft fluidic switch using an ionic polymer artificial muscle that runs with ultra-low power to lift objects 34 times greater than its weight. Its light weight and small size make it applicable to various industrial fields such as soft electronics, smart textiles, and biomedical devices by controlling fluid flow with high precision, even in narrow spaces.

A new study shows how state-of-the-art methods and perspectives from archaeology, history, and palaeoecology are shedding new light on 5,500 years of urban life.

Record heat across the world profoundly impacted the global water cycle in 2023, contributing to severe storms, floods, megadroughts and bushfires, new research shows.

A new wave of communication technology is quickly approaching and researchers are now investigating ways to configure next-generation mobile networks.

An international group of researchers finds that conserving about half of global land area could maintain nearly all of nature's contributions to people and still meet biodiversity targets for tens of thousands of species. But the same priority areas are at risk of conflict with human development with only 18% of that land area protected.

Peatlands are affected more by drought than expected. This is concerning, as these ecosystems are an important ally in the fight against climate change. Following long periods of drought, peat is able to absorb little to no extra carbon (CO2). Increasing biodiversity also does little to make peat more drought-resilient.

Combining a biological heart and a silicone robotic pump, researchers created a biorobotic heart that beats like a real one, with a focus on a valve on the left side of the heart. The heart valve simulator can mimic the structure, function, and motion of a healthy or diseased heart, allowing surgeons and researchers to demonstrate various interventions while collecting real-time data.

Researchers have found almost identical patterns of tree diversity across the world's tropical forests. The study of over one million trees across 1,568 locations found that just 2.2% of tree species make up 50% of the total number of trees in tropical forests across Africa, the Amazon, and Southeast Asia. Each continent consists of the same proportion of a few common species and many rare species.

The red-swamp crayfish Procambarus clarkii is a highly invasive species native to American freshwaters but has also invaded many freshwater ecosystems around the world. Now, researchers conducted a comparative analysis to compare reproductive characteristics of American crayfish with Japanese crayfish. They identified morphological characteristics which can aid in distinguishing the invasive properties of crayfish at the peak of their reproductive form, ultimately assisting in their effective population control.

Robots and autonomous vehicles can use 3D point clouds from LiDAR sensors and camera images to perform 3D object detection. However, current techniques that combine both types of data struggle to accurately detect small objects. Now, researchers have developed DPPFA Net, an innovative network that overcomes challenges related to occlusion and noise introduced by adverse weather. Their findings will pave the way for more perceptive and capable autonomous systems.

A new study describes nine new species of carnivorous land snails, all of which are so small they could fit together on a U.S. nickel. They present a rare opportunity to study a group that in many other places is disappearing fast. Worldwide, mollusks account for more than 50% of all recorded extinctions since the year 1500, and many of these were land snails from Pacific islands.

An international team of scientists has used a novel 500-year dataset to frame a 'restorative' pathway through which humanity can avoid the worst ecological and social outcomes of climate change.

Researchers have developed a new soft robot design that engages in three simultaneous behaviors: rolling forward, spinning like a record, and following a path that orbits around a central point. The device, which operates without human or computer control, holds promise for developing soft robotic devices that can be used to navigate and map unknown environments.

Frequent visits to oil palm plantations are leading to a sharp increase in mortality rates among infant southern pig-tailed macaques (Macaca nemestrina) in the wild, according to a new study. In addition to increased risk from predators and human encounters, exposure to harmful agricultural chemicals in this environment may negatively affect infant development.
