RNA blood test detects, classifies and pinpoints location of cancer

In an effort to find an accurate and easy method of detecting and locating cancers, negating the need for invasive cell tissue sampling, researchers from Umeå University in Sweden have developed a new blood test that looks at blood platelets in just a single drop of blood to identify cancer. Results of the method are very promising, with a 96 percent identification accuracy.

Hydrogel infused with snake venom stops bleeding within seconds

Major, uncontrolled blood loss can have major ramifications everywhere from the battlefield to the operating theatre. While blood-clotting medications can be used to stem the flow, often their purpose is thwarted by conflicting anti-coagulating drugs that thin the blood instead. But now scientists have developed a promising new hydrogel infused with snake venom that is drawn to the wound and shuts down bleeding in a matter of seconds.Read More

Leukometer promises needle-free monitoring of the immune system

Keeping track of white blood cell levels in chemotherapy patients is an involved but crucially important task. The treatment can lead to suppression of the immune system, a decline in white blood cell count, which in turn can give rise to infections and other serious complications. As things stand, patients are subjected to regular blood tests as a means of keeping an eye on things, but an international team of scientists has a less invasive alternative in the works. With the ability to tally up white blood cells through the skin in real time, the new testing device can simply be stuck onto a fingertip to help clinicians tailor personalized and more timely treatments.Read More

Tiny particles propel themselves upstream to stop severe internal bleeding

Though materials have been developed that clot blood in order to slow bleeding, when the bleeding is internal things get a little more complicated. The flow of blood makes it difficult to deliver these agents upstream to the site of the injury, but now a team of Canadian researchers says it may have a solution. It has developed a micro-sized particle that produces gas to propel itself against the tide.Read More

Whale protein puts researchers on path to developing synthetic blood

Researchers at Rice University have discovered that a protein found in whale meat may hold the key to developing synthetic blood. The protein, called myoglobin, allows marine mammals to remain submerged at great depths for up to two hours and has an ultra-stable structure that could one day allow for the manufacturing of a blood substitute using bacteria as biofactories.Read More

Moxy Sensor monitors muscle blood oxygen levels while you workout

Dizziness and severe shortage of breath is a pretty sure sign of overexertion, but sometimes you won't know you've pushed yourself too far until you're hunched over the park bench gasping for air. The stick-on Moxy Monitor is designed to give athletes a window into how their body is performing during a workout, by tracking blood oxygen levels in their muscles in real time and displaying this along with other fitness data in third party apps and devices.Read More

New blood clot-busting nanocapsule promises immediate care for heart attacks

When blood clots form in the aftermath of a heart attack or stroke, medications can be deployed to break them apart, but delivery is tricky. Getting the medicine to the clot takes some guesswork and there's no guarantee it will arrive in the right dosage, with complications like hemorrhaging a real possibility. A team of Australian scientists has developed a new approach that sees the drugs carried safely inside a nanocapsule, opening up the treatment to more patients and lessening the chance of side effects.Read More

Nicotine-gobbling enzyme could help smokers quit

Nicotine replacement therapy, such as pills, gum and patches, can make the road to quitting smoking a little less rocky, but these aren't always effective and a tremendous amount of discipline still plays the major role. A team of US-based researchers has now uncovered an enzyme found in nature they say could greatly improve on the effectiveness of smoking cessation aids, by devouring nicotine in smokers before it can deliver its "reward" to the brain.Read More

Study successfully uses drones to transport blood samples

We’ve already heard about drones being used to deliver pharmaceuticals to patients in remote locations, but scientists from Johns Hopkins University and Uganda’s Makerere University are now looking at the other end of the picture – using them to deliver remotely-located patients’ blood samples to labs in larger centers. According to a proof-of-concept study conducted by the researchers, the little unmanned aircraft should be able to do the job just fine.Read More

Laser device may soon non-invasively monitor diabetics' glucose levels

In order to monitor their blood glucose levels, diabetics typically have to perform painful and inconvenient finger-prick blood tests – in some cases, several times a day. Using an implantable glucose-monitoring sensor is one alternative, although it must be surgically installed and subsequently removed for replacement. Another option may be on the way, however, in the form of a device that simply shines a laser on the user's finger.Read More
