Researchers have developed a technique that allows stem cells to be created from less than...

Harvesting samples for producing stem cells can be rather painful. Techniques can involve collecting large amounts of blood, bone marrow or skin scrapes. The reality is intrusive measures such as these can be very off-putting. But what if it was as simple as a finger-prick? Such a DIY approach, which is so easy it can be done at home or in the field without medical staff, has been developed by researchers at Singapore's A*STAR Institute of Molecular and Cell Biology (IMCB).  Read More

A blood test could help reduce the risk of long-term damage for participants of contact sp...

It wasn't so long ago that shaking off a knock to the head and getting back on the field was seen as a sign of toughness for sportspeople. But in recent years, increased awareness of the potential for long-term damage has put the seriousness of concussion in the spotlight. Researchers at Sahlgrenska Academy in Sweden have now developed a blood test that reveals the severity of a concussion and when it is safe for a player to return to the game.  Read More

The optical device uses a laser to determine how quickly a person's blood will clot  (Imag...

Not everyone's blood clots at the same rate. While that might seem like simply an interesting bit of trivia, it's anything but trivial to doctors performing operations or emergency procedures, who need to know what might be required in the way of transfusions or anticoagulant drugs. Now, an optical device can provide them with that information within minutes.  Read More

The researchers used three specially developed inks that borrow biological properties from...

The notion of 3D printed biological tissue holds all kinds of possibilities for drug testing and the reparation of damaged cells, though replicating the complexities of human tissue in a lab presents some very big challenges. A new bioprinting method developed by researchers from the Wyss Institute for Biologically Inspired Engineering at Harvard University has enabled the creation of tissue constructs with small blood vessels and multiple cell types, marking important progress toward the printing of living tissue.  Read More

Polymers similar to the proteins found in this Arctic cod could dramatically improve the c...

How is it possible that cold-blooded fish such as cod can live in Arctic waters without just freezing solid? As it turns out, they've got proteins in their bloodstream that act as a sort of antifreeze. British scientists have now copied the fashion in which those proteins work, to create a process by which donated human blood could be frozen for storage, then quickly made available for transfusion.  Read More

Although a lot of people are concerned about monitoring their cholesterol levels, probably not many of those people want to head off to a clinic or use an expensive, complicated device to get those levels tested every few days. Soon, however, they may not have to. Scientists from Cornell University have developed a gadget called the smartCARD, that allows users to easily check their own cholesterol using their iPhone.  Read More

The active cannula goes to work on a simulated blood clot

Intracerebral hemorrhaging is what occurs when a blood vessel in the brain bursts, and the blood which subsequently leaks out of that vessel forms a clot that places pressure on the surrounding brain tissue. It’s not that uncommon of an occurrence, it’s difficult to treat, and is fatal in about 40 percent of cases. Help may be on the way, however. A team from Nashville’s Vanderbilt University has created a robotic device that is designed to remove those clots, in a safe and minimally-invasive fashion.  Read More

Qardio's QardioCore monitors EKG, physical activity, heart rate and skin temperature

Thanks to the miniaturization of electronics and wireless technology, detailed cardiovascular monitoring no longer requires a visit to the doctor's clinic or a hospital. A new wave of cardiovascular monitoring devices can be carried or worn by patients as they go about their daily routine, with the collected data able to be transmitted wirelessly to healthcare professionals and family members. Healthcare company Qardio has unveiled two such devices that allow patients suffering, or at risk of developing cardiovascular conditions, to better monitor their health.  Read More

Abnormal lymphocyte being attacked by macrophages (upper right), which lead to enhanced gr...

If a locked door must be opened, explosives can be used, but normally it is better to use a key. The conventional treatments for cancer, surgery, radiation, and chemotherapy, have a range of terrible side effects that resemble the use of explosives in search of health. Now a key has been found to treat various forms of leukemia and lymphoma with only very minor side effects. The drug ibrutinib has proven sufficiently safe and effective in early clinical tests by physicians at Ohio State University that it has been given breakthrough drug status by the FDA.  Read More

A glowing Japanese freshwater eel – it's more than just tasty

Just about any sushi-lover knows what unagi is – it’s eel, or more specifically, the Japanese freshwater eel Anguilla japonica. What those people might not know, however, is that the eel glows green in the dark. Now, it looks like the protein that allows the fish to do so could also help doctors to assess human liver function.  Read More
