A tiny chip with a unique surface can accurately detect the blood biomarkers of a heart attack within minutes, a fraction of the time taken by current methods, even if they’re at very low concentrations. The researchers behind the device see it being used as an at-home diagnostic tool.Continue ReadingCategory: ScienceTags: Biomarkers, Heart attack, Chip, metasurface, Johns Hopkins University

Microscopic pirates attack with cellular cannons and grappling hooks
Posted by ArielTechGeek 20 days ago (https://newatlas.com)
Microscopic battles rage around, on and in us at all times, and the microbial combatants use far more exciting weapons than we might realize. Scientists have now observed a bacterium that attacks like a pirate ship, ensnaring its prey with grappling hooks and firing “cannons” that blow it open.Continue ReadingCategory: Biology, ScienceTags: Bacteria, Cells, ETH Zurich
Video: Orca makes first-known solo attack on a great white shark
Posted by ArielTechGeek 247 days ago (https://newatlas.com)
For the first time ever, a lone orca has been observed killing and eating a great white shark. Although orcas were already known to hunt great whites in packs or pairs, one had never been seen going solo before. The finding suggests the emergence of a new hunting strategy.Continue ReadingCategory: Biology, ScienceTags: Sharks, Ecology, Behavior
Standard blood testing may provide warning of impending heart attack
Posted by ArielTechGeek 267 days ago (https://newatlas.com)
It can be hard to motivate yourself to take preventative measures against heart attack, if you don't know if you're even at risk of having one. According to new research, however, a standard blood test can now provide that information.Continue ReadingCategory: Health & Wellbeing, LifestyleTags: Uppsala University, Heart attack, Blood

Machine learning algorithm a fast, accurate way of diagnosing heart attack
Posted by ArielTechGeek 541 days ago (https://newatlas.com)
Heart attack symptoms are sometimes similar to non-heart-related conditions, making diagnosis tricky. UK researchers have turned to machine learning to provide doctors with a fast and accurate way of diagnosing heart attacks that has the potential to shorten the time needed to make a diagnosis and provide more efficient and effective treatment to patients.Continue ReadingCategory: Health & We
Long-term beta-blockers after heart attack offer no cardiovascular benefits
Posted by ArielTechGeek 554 days ago (https://newatlas.com)
Beta-blockers are prescribed as a matter of course to people following a heart attack, but a new study, the largest of its kind, has found that for people who have not experienced cardiac complications, taking beta-blockers for more than a year after a heart attack does not improve cardiovascular outcomes. The results may lead to a reassessment of the use of this commonly prescribed class of drug
Technique reverses heart attack damage by reprogramming scar cells
Posted by ArielTechGeek 565 days ago (https://newatlas.com)
For all they do for us, our hearts aren't very good at repairing themselves. So when a person suffers a heart attack, their blood pump is left with a large amount of scar tissue, which can impede the organ's flexibility and thereby its function. Inspired by the way young hearts heal themselves, researchers have now found a way to transmute scar tissue into healthy tissue in mice, thereby walking
Chronic inflammation discovery may turn the tide on heart attack, stroke
Posted by ArielTechGeek 573 days ago (https://newatlas.com)
We’re all familiar with acute inflammation – the redness, pain and bruising around injuries that alerts the immune system to the damage it needs to heal. However, if this response becomes prolonged, chronic inflammation can then see healthy tissue attacked and the risk of serious illness becomes increasingly greater.Continue ReadingCategory: Medical, ScienceTags: Heart attack, Cardiovascular, Str
