Bloodstream

In new research, the presence of a blood-based sugar molecule helped predict the onset of Alzheimer's up to a decade before symptoms appeared. The protocol could join others in spotting the condition early and slowing its progression.

Detecting circulating tumor cells among healthy blood cells is notoriously hard. Now an easy-to-use device can ID even a small number of cancer cells, potentially providing a huge breakthrough in non-invasive early detection, monitoring and treatment.

Researchers at the University of New South Wales have demonstrated how a microfluidic device that mimics the embryonic heart can produce blood stem cell precursors, which could let blood stem cells be manufactured on demand.

Everyone responds to general anesthetics differently, which can make administering the correct dose tricky. A new device is designed to help, by continuously monitoring anesthetic levels in patients' bloodstreams during surgical procedures.

Continuous blood monitoring would be a transformative advance for doctors and a new study brings that reality closer. New research describes a device that can detect real-time changes in blood levels of any molecule a doctor would need to monitor.

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.

Triglycerides are a form of fat that circulates through the bloodstream, and high levels can lead to obesity and related illnesses. Now, researchers have found a way to efficiently produce a protein that clears these fats from the bloodstream.

Researchers have discovered a new component in blood that has never been detected there before. Mitochondria are normally found inside cells, but the team has now discovered them floating around on their own in the bloodstream.

​A new study has found that four active ingredients in sunscreen can leech into a person's bloodstream at levels high enough to warrant further toxicology testing. Cancer experts say it’s unclear whether these chemical concentrations are dangerous to humans.​

A compelling new study from an international team of researchers has described a novel protein that could be a useful blood-based biomarker to monitor the progression of Alzheimer's disease over a decade before any clinical symptoms appear.

New research has revealed a promising new candidate to help smokers kick their damaging addiction. An enzyme has been engineered that can gobble up nicotine in the bloodstream before it reaches the brain, with the compound proving to be incredibly successful in early animal tests.

A fascinating cancer detection technique has been developed by scientists at Stanford University. The process involves a small magnetic wire being inserted into a vein where it attracts free-floating tumor cells in the blood.
