ShinyShiny Health Round Up: NHS uses AI to spot future heart attacks
The NHS is using artificial intelligence to treat patients at risk of a heart attack, years before they strike. CaRi-Heart can spot minor problems undetected by routine scans, Oxford University researchers say, identifying inflammation and scarring in the lining of blood vessels that supply the heart. The tool is being rolled out at 15 hospitals…
10 miniature medical miracles: tiny tech that could change our lives #HealthandFitnessWeek
Smartphones might be getting bigger, but smart medicine is only getting smaller and more sophisticated. From microchips that can diagnose diseases or control our fertility to scientific breakthroughs too tiny to see without a microscope, there's an increasing number of impressive miniature medical miracles in development that have the potential to revolutionise healthcare in the…
DNA can ‘glue’ 3D printed organs together
Scientists in the U.S have found that strands of DNA molecules can stick together 3D printed materials that could be used to make lab-grown organs and tissue. Andrew Ellington and colleagues from the University of Texas published their results in the American Chemical Society journal Biomaterials Science & Engineering. They found that coating polystyrene or…
Google’s new pill will search your body for cancer
In case you weren’t sure how serious Google were about world domination search, now they want to take their algorithms inside your body, too. Don’t worry, though: they come in peace. In fact, they only want to help you feel better and continue to use Google products live longer. Today, Google’s experimental division Google X…
This tiny gold device makes cancer treatment safer
Scientists have developed a tiny new device that can monitor the safety and effectiveness of cancer treatment. It measures the amount of methotrexate, a common medication, in the blood. Methotrexate works by blocking an enzyme that causes cancer cells to grow but in large doses it can be toxic, killing off healthy cells as well.…
A new gold patch could replace heart transplants
Scientists have developed a new patch that could remove the need for heart transplants. Because heart muscles contain few stem cells and heart cells are unable to reproduce, there’s no way for the heart to repair itself, for example after a heart attack. But Dr Tal Dvir and his graduate student Michal Shevach from Tel…
Could swallowing small needles replace injections?
Researchers in the U.S have invented a new acrylic capsule for delivering drugs straight into the digestive tract. It’s two centimetres long, one centimetre in diameter, has a space inside for medication and, oh yes, is covered in needles. When it’s swallowed, it releases the drug into the stomach lining. As horrifying as swallowing needles…
Researchers have made the world’s biggest DNA origami
And you thought being able to fold a single sheet of paper into a crane was impressive. Scientists from North Carolina State University, Duke University and the University of Copenhagen have taken origami to the next level with the creation of the world’s biggest DNA origami. And not just to impress us with their skills:…
This new electronic skin can detect breast cancer
Scientists have developed an electronic skin that is better at detecting breast cancer in the early stages than either a doctor's exam or mammogram. While mammograms can discover cancer in younger women, they're less likely to be effective than in women over 50, because younger women's breast tissue is more dense. Ultrasounds are helpful but…
3D printers can make medication implants now
Scientists from Louisiana Tech University have pioneered a new way to deliver medication using a standard 3D printer. As Science Daily reports, the research team, which was made up of staff and doctoral students from the biomedical engineering and nanosystems engineering courses, designed extruders (the nozzle that pushes out the end product) suitable for medical-grade…
