Bloodstream

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.

A new therapy designed at Penn State has turned one of cancer's tactics against it. The team camouflaged a cancer-killing drug using cells from the tumor itself, allowing them to sneak medicine past the tumor’s defenses like a nanoscale Trojan horse and deliver a killing blow from the inside.

A new breakthrough at the University of Colorado is the latest advance in the burgeoning realm of anti-aging science, demonstrating how a chemically altered nutritional supplement may well reverse aging of the blood vessels, in turn giving cardiovascular health a vital boost. ​

​Major internal bleeding is a very serious condition that requires immediate attention, and it's difficult to treat non-surgically. Scientists from Russia's ITMO University are working on an effective means of doing so, however, in the form of injectable magnetic nanoparticles.

​Using principles similar to those deployed in large hydroelectric power plants, a team of Chinese researchers has developed a tiny nanogenerator that can potentially sit inside a vein and generate electricity from blood rushing through it.

According to the CDC, every year 60,000-100,000 people die in the US alone from blood clots formed from conditions known as deep vein thrombosis or pulmonary embolisms. Now, a new patch developed by researchers in North Carolina could help battle these life-threateners in a novel way.

Science fiction is fast becoming reality, with scientists in South Korea developing an astonishingly fast-moving remote-controlled microrobot designed to travel through the human bloodstream to deliver treatment directly to the organs that need it.
