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
Post-apocalyptic star systems could reveal the fate of our own. The post The Stars Foretell Our Doom appeared first on Nautilus .
A winning photograph shows millions of Monarchs dripping from Mexico’s fir trees in winter. The post The Haunted Forest of Butterflies appeared first on Nautilus .
This year’s first presidential debate between President Joe Biden and former president Donald Trump featured clashes over insulin costs, inflation, abortion, immigration, and January 6
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
With lunar exploration ramping up, NASA has been tasked with defining a time zone for the moon. New calculations show that time is ever so slightly faster on the lunar surface, which can affect navigation
Fifty years after scientists identified the cause of Pierce's disease, which damages vineyards, there still isn't a cure.
A team of researchers led by an archaeologist at the University of Sydney are the first to suggest that eyed needles were a new technological innovation used to adorn clothing for social and cultural purposes, marking the major shift from clothes as protection to clothes as an
NASA's Mars InSight Lander may be resting on the Red Planet in retirement, but data from the robotic explorer is still leading to seismic discoveries on Earth.
An asteroid will whiz harmlessly past Earth this weekend. With the right equipment and timing, you just might spot it.
Two major US healthcare organisations have offered contradictory advice about the use of weight loss drugs in adolescents with obesity, underscoring just how little we know about the effects of these medications
Flooding from a similar earthquake today could threaten about 170 million people in India and Bangladesh who live in low-lying regions nearby.
This study is reported by Shisheng Chen's group at the National Key Laboratory of Wheat Improvement, Peking University Institute of Advanced Agricultural Sciences. Plant architecture has significant impact on plant development and productivity, and thus has been extensively
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
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
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
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
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
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
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
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
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.
