Engineers have developed a pioneering prosthetic hand that can grip plush toys, water bottles, and other everyday objects like a human, carefully conforming and adjusting its grasp to avoid damaging or mishandling whatever it holds.

Working at nanoscale dimensions, billionths of a meter in size, a team of scientists revealed a new way to measure high-speed fluctuations in magnetic materials. Knowledge obtained by these new measurements could be used to advance technologies ranging from traditional computing to the emerging field of quantum computing.

Theoretical physicists reveal that room-temperature superconductivity is possible within the laws of our Universe, linked to fundamental constants like electron mass and Planck constant. Discovery could revolutionize energy, quantum computing, and medical tech by enabling superconductors to work at ambient conditions. Research explores how varying fundamental constants could alter superconductivity limits, offering a glimpse into the delicate balance of our Universe.

Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of researchers presents a novel machine learning method that can analyze gravitational waves emitted by neutron star collisions almost instantaneously -- even before the merger is fully observed. A neural network processes the data and enables a fast search for visible light and other electromagnetic signals emitted during the collisions. This new method could be instrumental in preparing the field for the next generation of observatories.

Scientists encased nanodiamonds in tiny moving droplets of water to improve quantum sensing. The new technique lets researchers detect trace amounts of certain ions and molecules, and could someday find applications in environmental monitoring, medicine, bioengineering, and more.

Researchers are working to move cold atom quantum experiments and applications from the laboratory tabletop to chip-based systems.

Soilless growing systems inside greenhouses, known as controlled environment agriculture, promise to advance the year-round production of high-quality specialty crops, according to an interdisciplinary research team. But to be competitive and sustainable, this advanced farming method will require the development and implementation of precision agriculture techniques. To meet that demand, the team developed an automated crop-monitoring system capable of providing continuous and frequent data about plant growth and needs, allowing for informed crop management.

Researchers have demonstrated that multicolored stickers applied to stop or speed limit signs on the roadside can 'confuse' self-driving vehicles, causing unpredictable and possibly hazardous operations.

The puzzle of predicting how three gravitationally bound bodies move in space has challenged mathematicians for centuries, and has most recently been popularized in the novel and television show '3 Body Problem.' There's no problem, however, with what a team of researchers say is likely a stable trio of icy space rocks in the solar system's Kuiper Belt.

Technology is changing how physicians think about assessing patients and, in turn, how patients expect to be able to measure their own health. Apps designed for smartphones and wearable devices can provide unique insights into users' brain health. It is estimated that 55 million individuals worldwide suffer from some form of dementia. Alzheimer's disease and related dementias being the leading causes, with numbers expected to triple by 2050.

Researchers have created a system to help beekeepers monitor and analyze the health of their beehives and take corrective actions to prevent colony collapse -- when a majority of the worker bees abandon the colony and its queen. Beehives use thermoregulation to ensure the hive temperature stays between 33 and 36 degrees Celsius, about 91 to 97 degrees Fahrenheit. For example, bees might cluster to create insulation when it's cold or fan their wings when it's hot. But when beehives experience external stressors, such as pesticides or unexpected weather events, they lose the ability to regulate the hive temperature.

A team unveils a versatile large language model to enhance perioperative care.

A research team is studying whether artificial intelligence (AI) could play a supportive role in the evaluation of respiratory disease in pigs.

A research team has recently developed a groundbreaking neuromorphic exposure control (NEC) system that revolutionizes machine vision under extreme lighting variations. This biologically inspired system mimics human peripheral vision to achieve unprecedented speed and robustness in dynamic perception environments.

Engineers have developed a new computational approach to accurately model and predict the properties of a class of magnetic molecules called chiral helimagnets. Their work could accelerate the discovery of new materials for spintronics technologies.

Everyday smartwatches are extremely accurate in detecting viral infection long before symptoms appear -- now, research shows how they could help stop a pandemic before it even begins.

For decades, scientists have relied on electrodes and dyes to track the electrical activity of living cells. Now, engineers have discovered that quantum materials just a single atom thick can do the job with high speed and resolution -- using only light.

Glaucoma is called the 'silent thief of sight' as many don't notice until significant, irreversible vision loss has already occurred. A revolutionary early screening tool using AI may stop this thief dead in its tracks.

Distressing news and traumatic stories can cause stress and anxiety -- not only in humans, but these stories can also affect AI language models, such as ChatGPT. Researchers have now shown that these models, like humans, respond to therapy: an elevated 'anxiety level' in GPT-4 can be 'calmed down' using mindfulness-based relaxation techniques.

Novel technology intends to redefine the virtual reality experience by expanding to incorporate a new sensory connection: taste.
