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

Scientists turn blood into nerve cells in pursuit of better pain relief

As it stands, there's not a whole lot we know about pain. Where a tissue or blood sample can be drawn and studied, our nervous system comprising different kinds of cells running signals through complex piping around the body presents a difficult task for scientific research. But a new study details a technique that turns blood cells into different nerve cells, promising to improve our understanding of why things itch or burn. By extension, it is hoped that it could lead to new forms of pain relief that do away with unwanted side effects such as sleepiness or loss of concentration.Read More

Enzyme could make any type of donated blood safe for anyone to receive

When it comes to donated blood, type O is special. It can be given to anyone, regardless of their blood type. By contrast, type A can only go to A or AB patients, and B can only go to B or AB patients. Additionally, type O patients can only receive O. Thanks to new research, however, it may soon be possible to give anyone whatever type of blood happens to be available, with no ill effects. Read More

New sampling device promises to make blood tests needle-free

Though the pain they cause is minor and fleeting, a lot of people still find something pretty unsettling about needles. When it comes to conducting a routine blood test, US-based company Tasso Inc. believes that these unpleasant pricks can be removed from the equation completely. Its ping pong ball-sized HemoLink blood sampler can be operated by the patient at home, and needs only to be placed against the skin of the arm or abdomen for two minutes to do its job.Read More
