Phys.org / Strontium optical clock accurate to within 1 second over 30 billion years
Researchers from the University of Science and Technology of China have achieved a major breakthrough in optical clock technology, developing a strontium optical lattice clock with stability and uncertainty both surpassing ...
Tech Xplore / Improving AI models' ability to explain their predictions
In high-stakes settings like medical diagnostics, users often want to know what led a computer vision model to make a certain prediction, so they can determine whether to trust its output. Concept bottleneck modeling is one ...
Phys.org / Silicone wristbands can help scientists track people's exposure to pollutants like 'forever chemicals'
Every morning, people fasten their watch, slip on a bracelet and head out the door without thinking much about what they might encounter along the way. The air they breathe, the dust on their hands and the surfaces they touch ...
Medical Xpress / Biomimetic platform developed to enhance CAR T cell therapy against leukemia
Chimeric antigen receptor T (CAR T) cell therapy represents a milestone in leukemia treatment. CAR T works by genetically engineering a chimeric antigen receptor on the surface of the patient's T cells to target specific ...
Phys.org / Study finds teens spend nearly a third of the school day on smartphones: Frequent checking linked to poorer attention
A new study from researchers at University of North Carolina at Chapel Hill finds that middle and high school students spend nearly one-third of the school day on their smartphones, checking them dozens of times, often for ...
Medical Xpress / Policy change tied to higher kidney transplant rates for Black patients
A new national study evaluating a landmark U.S. transplant policy change finds that efforts to correct the harms of race-based kidney function equations are associated with increased kidney transplantation rates among Black ...
Tech Xplore / New 'negative light' technology hides data transfers in plain sight
Engineers at UNSW Sydney and Monash have developed an innovative way of sending hidden information that's hard to intercept. Using a phenomenon known as "negative luminescence," the system works by making signals blend perfectly ...
Medical Xpress / Immune cells play key role in regulating eye pressure linked to glaucoma, research reveals
When the eye's drainage system clogs, pressure builds up and causes damage. The pressure can lead to glaucoma and vision loss. New research, published in the journal Immunity, reveals that a specialized set of immune cells ...
Phys.org / 'Peculiar' crocodile ancestor started life on four legs before learning to walk on two
A "peculiar" ancient relative of the crocodile which experts believe began life on four legs before, in adulthood, it learned how to walk on just two has been revealed in a new study. Named Sonselasuchus cedrus, this archaic ...
Tech Xplore / AI fake-news detectors may look accurate but fail in real use, study finds
A dubious link from a friend. A headline too sensational to be true. A video that seems fake but you can't be sure. As online misinformation grows harder to detect, new artificial-intelligence tools promise to help us separate ...
Tech Xplore / Deep AI training gets more stable by predicting its own errors
Artificial intelligence now plays Go, paints pictures, and even converses like a human. However, there remains a decisive difference: AI requires far more electricity than the human brain to operate. Scientists have long ...
Medical Xpress / New 3D material enables brain cells to communicate
Until now, conventional 3D cell cultures have often been either too rigid or too unstable to realistically reproduce the complex interactions between brain cells. Researchers at Kiel University (CAU) have now developed a ...
