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.
Researchers have developed a technique to connect lab-grown neural 'organoids' (three-dimensional developmental brain-like structures grown from human stem cells) using axonal bundles, similar to the connections between regions in the human brain. This technique allows brain networks to be better represented experimentally in the lab, and will improve understanding and studies of network-related brain disorders.
In a new breakthrough that could revolutionise medical and material engineering, scientists have developed a first-of-its-kind molecular device that controls the release of multiple small molecules using force.
The man behind the poorly named “God particle” shunned fame, shared credit on his most important work, and may not have made it in 21st century academia
Engineered bacteria can produce a plastic modifier that makes renewably sourced plastic more processable, more fracture resistant and highly biodegradable even in sea water. The development provides a platform for the industrial-scale, tunable production of a material that holds great potential for turning the plastic industry green.
Those who availed telemedicine saved 1,666 km of travel on average and lowered carbon dioxide emissions by 176.6 kg over three months
New research shows that people recognize more of their biases in algorithms' decisions than they do in their own -- even when those decisions are the same.
In a study that spans more than a decade, researchers have looked at generations of families in a specific population to reveal the role newly inherited DNA variants play on recessive disease traits, and in the process, they have created a population specific database revealing unique DNA information unseen in larger cohorts.
The bitter taste of certain drugs is a barrier to taking some medications as prescribed, especially for people who are particularly sensitive to bitter taste. A team found that the diabetes drug rosiglitazone could partially block the bitter taste of some especially bad-tasting medications. The hope is that repurposed drugs could be added in small doses to other medicines to make them less bitter and taste better, thereby encouraging compliance with bitter drug regimens.
Wirelessly connected devices perform an expanding array of applications, such as monitoring the condition of machinery and remote sensing in agricultural settings. These applications hold much potential for improving the efficiency, but how do you power these devices where reliable electrical sources are not available? Research points to a possible solution in the form of a novel type of battery.
