Blood

Some are born with three arteries in their forearm, and a new study is suggesting more and more people are holding onto this temporary embryonic artery into adulthood, which the researchers believe could be natural selection at work.

Scientists in China and Switzerland have teamed up to produce an implantable medical device that mimics the primary function of blood vessels, but goes a number of steps further than its natural counterparts.

Preliminary research has discovered several blood-based biomarkers which can specifically indicate stroke damage to brain tissue. The goal of the research is to develop a simple blood test to rapidly detect whether a patient is suffering a minor stroke.

A team of researchers from Massachusetts General Hospital, trawling through hospital admission data, may have found a simple blood-based biomarker that can help doctors assess those patients most at risk of suffering the worst effects of COVID-19.

A blood test that reveals the severity of brain injuries in hours through a key biomarker was recently approved for clinical use, but researchers are now setting their sights on a point-of-care solution that can deliver results within 15 minutes.

New research is suggesting a simple saliva test can detect the presence of a protein biomarker known to signal the occurrence of a heart attack in just 10 minutes, potentially accelerating the speed at which patients can be diagnosed and treated.

An international team of researchers has used machine learning to produce a novel blood test that can predict a young person’s risk of developing a psychotic disorder, such as schizophrenia, years before the condition develops.

A new study, led by researchers from University College London, is offering some of the first robust evidence showing how CBD, a key compound in cannabis, increases cerebral blood flow in memory processing regions of the brain such as the hippocampus.

Treatments for blood clots in the body naturally come with a risk of excessive bleeding from an injury. But a new synthetic blood thinner bypasses this side effect, fighting thrombosis while still allowing blood to clot normally in a wound.

First responders don’t have the same tools that emergency rooms do. Now, Harvard scientists have developed a new blood-clotting material that’s portable and easy to store, potentially helping injured patients survive long enough to reach a hospital.

In people with liver disease or other metabolic disorders, blood ammonia levels can quickly climb to dangerous levels. And unfortunately, checking those levels is not a fast and easy process. A newly developed device, however, could change that.

A new cancer-detecting blood test has been found to catch five common types of cancer up to four years before any other conventional diagnostic tool, but further verification is needed before the test is clinically available.
