Blood

An infusion of blood from young mice has led to cognitive improvements in older mice (Phot...

A literal infusion of some "young blood" has the ability to turn back the clock and restore the mental capabilities of old mice, according to a study conducted by researchers at the Stanford University School of Medicine. If similar results are seen in humans, the simple technique could lead to new treatments for forms of dementia, such as Alzheimer's disease.  Read More

Research suggests a blood test to detect depression is possible (Photo: Shutterstock)

At present, reaching a diagnosis for depression typically involves interviews with the patient, resulting in a drawn out and costly process. Some recent research efforts have sought to address this, such as a diagnostic technique that measures electrical activity in the brain to more quickly detect mental illness. Now a team of Austrian researchers has demonstrated a link between levels of serotonin in the blood and the depression network in the brain, meaning that diagnosing depression could soon become a much more efficient undertaking.  Read More

In the not-too-distant future, blood made with lab-grown red blood cells could be readily ...

According to the World Health Organization, approximately 107 million blood donations are collected globally every year. Nonetheless, blood is often in short supply – particularly in developing nations. Despite new safeguards, there's also still the risk of incompatibility, or of infections being transmitted from donors to recipients. Charitable organization the Wellcome Trust hopes to address these problems, by developing the ability to manufacture blood outside of the body. Last week, it announced that test subjects should begin receiving transfusions of blood made with lab-grown red blood cells by late 2016.  Read More

The final Hemosep, developed using 3D-printed prototype parts

During surgery, patients' blood is often "spilt." Such blood can be returned to the body, so long as it has been properly processed to ensure that it is not tainted. The Brightwave Hemosep autotransfusion machine can do this – and its prototyping costs have been cut by 96 percent via 3D printing.  Read More

A link found between breathing patterns and altitude sickness symptoms could lead to a tre...

Headaches, nausea, weakness and dizziness, combined with a feeling that you just can’t get enough oxygen with each breath are just some of the signs of altitude sickness. Researchers have now found a link between the abnormal breathing patterns experienced while sleeping at altitude and the symptoms of altitude sickness, particularly headaches. The finding suggests that finding a way to breath normally while sleeping could provide a way to combat such symptoms.  Read More

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
