With a new surgical intervention and neuroprosthetic interface, researchers restored a natural walking gait in people with amputations below the knee. Seven patients were able to walk faster, avoid obstacles, and climb stairs more naturally than people with a traditional amputation.
Computer scientists have invented a camera mechanism that improves how robots see and react to the world around them. Inspired by how the human eye works, their innovative camera system mimics the tiny involuntary movements used by the eye to maintain clear and stable vision over time.
To advance soft robotics, skin-integrated electronics and biomedical devices, researchers have developed a 3D-printed material that is soft and stretchable -- traits needed for matching the properties of tissues and organs -- and that self-assembles. Their approach employs a process that eliminates many drawbacks of previous fabrication methods, such as less conductivity or device failure, the team said.
Astronomers have discovered the first millisecond pulsar in the stellar cluster Glimpse-CO1.
Increased atmospheric moisture may alter critical weather patterns over Africa, making it more difficult for the predecessors of many Atlantic hurricanes to form, according to a new study.
Shrinking glaciers expose new land in the Arctic, creating unique ecosystems. Researchers studied how microbes colonize these barren landscapes. The study reveals a crucial role for specific fungal species in capturing and storing carbon in the newly formed soil. These findings suggest fungi are essential for future carbon storage in the Arctic as glaciers continue to recede.
Scientists found the choroid plexus and cerebrospinal fluid play a key role in maintaining a pool of newly born neurons to repair the adult brain after injury.
Pioneering AI-powered research on butterflies has probed the under-studied evolution of females and adds to a debate between Charles Darwin and Alfred Russel Wallace.
Archaeologists face a major challenge when they intend to acquire information about buildings or facilities of which only ruins remain. This was a particular challenge for the remnants of the Roman water mills in Barbegal in Southern France, dating back to the 2nd century CE. This unique industrial complex consisted of 16 water wheels placed in parallel rows. Little could at first be deduced about the site from these now scant ruins -- except that the wheels were supplied by an aqueduct that brought water from the surrounding hills. Researchers have now unraveled the history of the mill complex using calcium carbonate deposits that are now stored in the Archaeological Museum of Arles. These deposits had formed towards the end of the roughly 100-year operational life of the Barbegal water mills on the sides and base of the wooden supply system that conveyed the water to the wheels.
Short-lived neural connections in the mouse brain help prime sensory circuits, forever affecting the mouse's sense of touch. Neuroscientists have discovered that a receptor protein named mGluR1 helps regulate the timing of these temporary connections. Their findings may help reveal the origins of various neurodevelopmental disorders and new ways of treating them.
A team of researchers have identified unexpected ways coral reef fish living in the warmest waters on earth, in the Arabian Gulf, have adapted to survive extreme temperatures.
Researchers have developed a lightweight fluidic engine to power muscle-mimicking soft robots for use in assistive devices. What sets the new engine apart is its ability to generate significant force without being tethered to an external power source.
A study provides new clues in the understanding of how antibiotic resistance spreads. The study shows how an enzyme breaks down the bacteria's protective outer layer, the cell wall, and thus facilitates the transfer of genes for resistance to antibiotics.
Multiple myeloma is one of the most common forms of cancer of the immune cells in the bone marrow. It is considered incurable. Even when patients respond to treatment at first, the cancer comes back. To be able to intervene faster and on a more targeted basis, researchers completed a comprehensive study of this disease at the molecular level.
A research team has bridged a knowledge gap in atomic-scale heat motion. This new understanding holds promise for enhancing materials to advance an emerging technology called solid-state cooling.
Researchers have figured out how to turn ordinary white fat cells, which store calories, into beige fat cells that burn calories to maintain body temperature.
GPS tracking collars have revealed how newly reintroduced eastern quolls are settling in at Mulligans Flat Woodland Sanctuary in Canberra, with quolls who were born at the sanctuary accepting their new neighbors with open paws.
Researchers have discovered another factor that affects the composition of the gut microbiome: time of day.
Genes can indirectly influence the age at which girls have their first period by accelerating weight gain in childhood, a known risk factor for early puberty. Other genes can directly affect age of puberty, some with profound effects.
Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
