Komodo dragon genome reveals clues about its evolution

The Komodo dragons are the largest lizards in the world. These predators weighing up to 200 pounds can detect their prey from up to 7.5 miles away. And although they are cold-blooded, they can ramp up their metabolism to ...

Claw-like nanowires filter bacteria from blood

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 ...

Blood testing via sound waves may replace some tissue biopsies

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 ...

Researchers find ancient DNA preserved in modern-day humans

Residents of the remote equatorial islands of Melanesia share fragments of genetic code with two extinct human species. That's the key finding of a new study published March 17 in the journal Science.

New microchip sorts white blood cells from whole blood

Early in 2012, MIT scientists reported on the development of a postage stamp-sized microchip capable of sorting cells through a technique, known as cell rolling, that mimics a natural mechanism in the body. The device successfully ...

Researchers devise a new way to plot circadian clock

(Phys.org)—Everyone has an internal clock, that mysterious process which controls sleeping and hunger patterns, but now researchers are finding out that because the internal clock also controls metabolism, it would be helpful ...

Venipuncture

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.
