A loss of salt and body fluid can stimulate kidney regeneration and repair in mice, according to a new study. This innate regenerative response relies on a small population of kidney cells in a region known as the macula densa (MD), which senses salt and exerts control over filtration, hormone secretion, and other key functions of this vital organ.

Researchers have sent data at a record rate of 402 terabits per second using commercially available optical fiber. This beats their previous record, announced in March 2024, of 301 terabits or 301,000,000 megabits per second using a single, standard optical fiber.

A new computational microscopy technique solves for true high-resolution images without the guesswork that has limited the precision of other techniques.

Researchers have developed a python-tooth-inspired device as a supplement to current rotator cuff suture repair, and found that it nearly doubled repair strength. Their biomimetic approach following the design of python teeth helps to reattach tendons to bone more securely. The device not only augments the strength of the repair but can also be customized to the patient.

Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard was discovered.

A recent discovery by NASA's James Webb Space Telescope (JWST) confirmed that luminous, very red objects previously detected in the early universe upend conventional thinking about the origins and evolution of galaxies and their supermassive black holes.

A team of researchers has developed a soft, stretchy electronic device capable of simulating the feeling of pressure or vibration when worn on the skin. This device represents a step towards creating haptic technologies that can reproduce a more varied and realistic range of touch sensations for applications such as virtual reality, medical prosthetics and wearable technology.

Researchers have reported finding major differences between postmortem and living prefrontal cortex brain tissues as they relate to one of the most abundant RNA modifications in the brain, known as adenosine-to-inosine (A-to-I) editing.

Researchers developed a new wireless receiver that can block strong interference signals at the earliest opportunity, which could improve the performance of a mobile device.

The Coral Triangle, also known as the Indo-Australian Archipelago, is renowned for having the greatest marine biodiversity on our planet. Despite its importance, the detailed evolutionary history of this biodiversity hotspot has remained largely a mystery. An international research team has now shed light on this history, reconstructing how biodiversity in the region has developed over the past 40 million years.

A research team has shown that exposure to air pollution during childhood is directly associated with bronchitis symptoms as an adult. To date, many investigations have established air pollution exposure while young is consistently associated with lung problems during childhood -- and childhood lung problems are consistently associated with lung issues as an adult.

A new study explores waste management systems and reveals that achieving zero waste leakage by 2030 is unlikely, potentially jeopardizing related Sustainable Development Goals. The authors emphasize the need for global cooperation, particularly across four regions, to responsibly manage waste disposal.

Researchers have found that artificial intelligence models that are most accurate at predicting race and gender from X-ray images also show the biggest 'fairness gaps' -- that is, discrepancies in their ability to accurately diagnose images of people of different races or genders.

Atmospheric scientists predict that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be spurred by carbon emissions that influence the formation of the intertropical convergence zones that are essentially atmospheric engines that drive about a third of the world's precipitation.

A recent study shows that people are commonly given misleading information about depression. According to the researchers, the inaccurate information makes it harder for people to understand the causes of their distress.

Computer scientists have written a network flow algorithm that computes almost as fast as is mathematically possible. This algorithm computes the maximum traffic flow with minimum transport costs for any type of network. It thus solves a key question in theoretical computer science. The superfast algorithm also lays the foundation for efficiently computing very large and dynamically changing networks in the future.

Bringing a puppy home is usually a happy event, but sometimes the life change that comes with it can provoke significant negative emotions. Researchers found that almost half of dog owners experience anxiety, weariness or frustration during their dog's puppyhood stage.

A new study tracked a cohort of testicular cancer survivors who received cisplatin-based chemotherapy for an average of 14 years, revealing that 78% experience significant difficulties in everyday listening situations, negatively impacting their quality of life.

The new research suggests answers to why children with relapsing Crohn's endure repeated bouts even after appearing to recover. Doctors may be able to target this underlying cause to better treat Crohn's -- or even cure it.

A new study has produced supranormal hearing in mice, while also supporting a hypothesis on the cause of hidden hearing loss in people.
