Children and young people who are overweight or obese are at significantly higher risk of iron deficiency, according to a study by nutritional scientists.
Researchers applied artificial intelligence (AI) to a technique that produces high-resolution images of cells in the eye. They report that with AI, imaging is 100 times faster and improves image contrast 3.5-fold. The advance, they say, will provide researchers with a better tool to evaluate age-related macular degeneration (AMD) and other retinal diseases.
Researchers have discovered the connection between aldehydes, organic compounds produced by cells as part of metabolic processes, and rapid aging. Their findings indicate a potential treatment for diseases that lead to accelerated aging as well as a means to counteract aging in healthy people by controlling exposure to aldehyde-inducing substances including alcohol, pollution, and smoke.
The path to quantum supremacy is made challenging by the issues associated with scaling up the number of qubits. One key problem is the way that qubits are measured. A research group introduces a new approach that tackles these challenges head-on using nanobolometers instead of traditional, bulky parametric amplifiers.
Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth -- and it could help assess which other planets can develop life, ranging from plants to animals and humans.
Researchers have developed a digital display screen where the LEDs themselves react to touch, light, fingerprints and the user's pulse, among other things. Their results could be the start of a whole new generation of displays for phones, computers and tablets.
Scientists have identified sugar abnormalities in the blood that may promote biological aging and inflammation in people living with HIV.
Chemists show that a machine-based method prevents widespread 'bias' in chemical publications.
Researchers decode repair mechanism during transcription of genetic information.
When scuba divers need to say 'I'm okay' or 'Shark!' to their dive partners, they use hand signals to communicate visually. But sometimes these movements are difficult to see. Now, researchers have constructed a waterproof 'e-glove' that wirelessly transmits hand gestures made underwater to a computer that translates them into messages. The new technology could someday help divers communicate better with each other and with boat crews on the surface.
Forensic and environmental experts have teamed up to develop a new scientific method to pinpoint microplastic pollution 'hotspots' in open waters.
Over 200 million people around the world experience peripheral artery disease (PAD) -- a condition caused by the narrowing of the blood vessels from the heart to the lower limbs that leads to pain when walking -- and for roughly 1-in-10 this advances to chronic limb-threatening ischemia (CLTI), an advanced form of PAD. Those with CLTI often suffer severe pain even at rest, caused by fatty plaque buildup obstructing blood flow, typically to the leg or foot.
A large randomized trial shows that a new three-step prostate cancer screening method can find a considerable number of aggressive cancers. Population-level screening programs have not been launched in most countries.
A survey of orchid bees in the Brazilian Amazon state of Rond nia, carried out in the 1990s, is shedding new light the impact of deforestation on the scent-collecting pollinators, which some view as bellwethers of biodiversity in the neotropics.
A new review of research evidence has explored the key differences in how women and men sleep, variations in their body clocks, and how this affects their metabolism.
As the centennial of the Scopes Monkey Trial of 1925 approaches, a new study illustrates that the attitudes of Americans in Generation X toward evolution shifted as they aged.
A noninvasive brain stimulation treatment improved depression and anxiety symptoms among older adults in a new study.
One of the molecules responsible for triggering the inflammation that causes allergic respiratory diseases, such as asthma and allergic rhinitis, has just been discovered. This molecule, from the alarmin family, represents a therapeutic target of major interest for the treatment of allergic diseases.
A study has analyzed the impact of the rise in sea surface temperature on macroalgae communities over the last four decades. Points at various depths were investigated in a location off the coast of Biscay, and an increasing scarcity was observed in the number of cold-affinity structuring species, while small warm-affinity ones have proliferated. The researchers are warning that some ecological functions are in jeopardy as a result.
Researchers showed that AI assistance potentially could improve breast-cancer screening by reducing the number of false positives without missing true positives.
