New photonic tools for medical imaging can be used to understand the nonlinear behavior of laser light in human blood for theranostic applications. When light enters biological fluids it is quickly scattered, however, some ...
A team of researchers with the Yellowstone Wolf Project at the Yellowstone Center for Resources, in Yellowstone National Park, in Wyoming, has found that wolves in the park who become infected with Toxoplasma gondii, a common ...
Astronauts are at higher risk for developing mutations—possibly linked to spaceflight—that can increase the risk of developing cancer and heart disease during their lifetimes, according to a first-of-its kind study from ...

A hefty set of tusks is usually an advantage for elephants, allowing them to dig for water, strip bark for food and joust with other elephants. But during episodes of intense ivory poaching, those big incisors become a liability.

A team of researchers from institutions across China has developed a new type of dialyser —one capable of capturing up to 97 percent of bacteria present in a blood sample. In their paper published in the journal Nature ...
Cells secrete nanoscale packets called exosomes that carry important messages from one part of the body to another. Scientists from MIT and other institutions have now devised a way to intercept these messages, which could ...

In medicine venipuncture or venepuncture is the process of obtaining intravenous access for the purpose of intravenous therapy or obtaining a sample of venous blood. This procedure will be performed by medical practitioners, some EMTs, paramedics, phlebotomists and other nursing staff.
Blood is most commonly obtained from the median cubital vein, on the anterior forearm (the side within the fold of the elbow). This vein lies close to the surface of the skin, and there is not a large nerve supply.
Minute quantities of blood may be taken by fingersticks sampling and collected from infants by means of a heel stick or from scalp veins with a butterfly needle.
Phlebotomy (incision into a vein) is also the treatment of certain diseases such as hemochromatosis and primary and secondary polycythemia.
