Blood

Blood samples taken from Russian cosmonauts before and after long stints on the ISS have revealed elevations of biomarkers that could indicate brain damage, adding to a growing body of research highlighting the deleterious effects of space travel.

We currently rear animals for meat and dairy, cut down forests for wood, harvest organs from the deceased and mine the earth for diamonds. But what if all these things, and more, could be grown in a lab?

It’s hard to get medical adhesives to stick when blood is making everything wet. Now, MIT researchers have developed a new surgical glue that can halt bleeding within 30 seconds, inspired by the super-strong underwater adhesive used by barnacles.

​When it comes to frivolous gadgets, fidget spinners would seem to be one of the most … well, frivolous. Recently, however, scientists from National Taiwan University discovered that the devices could be used for blood sample analysis in impoverished regions.

Zipline is looking to build on its success in Rwanda, today announcing plans to expand its blood-by-drone delivery service to Tanzania. The venture is billed as the world's largest drone delivery service, and will bring medical supplies to over one thousand health facilities around the nation.

Moscow-based media artist Dmitry Morozov's wacky art/music projects include the electropollock painting machine, the volnovod cable twister and the pyrite sun player. For his latest creation, he's built a synthesized sound maker powered by his blood. Lots and lots of blood.​

​​When a medical implant is rejected by the body, blood platelets adhere to the device, forming a clot that encapsulates it. Engineers at Colorado State University, however, have developed blood-repellent titanium that could be used to build such implants.​

​Many of us have played with whirligigs as kids, but now these playthings made of buttons and twine are getting a new life as medical lab tools.

The main issue of lithium-air batteries is lack of efficiency and lithium peroxide build up. But now a team at Yale has used a molecule found in blood as a catalyst, which not only improved the lithium-oxygen function, but may help reduce biowaste.

The stick-on Moxy Monitor is designed to give athletes a window into how their body is performing during a workout by tracking blood oxygen levels in the muscles in real time and displaying this along with other fitness data in third party apps and devices.

During surgery, patients' blood is often "spilt." Such blood can be returned to the body, so long as it has been properly processed to ensure that it is not tainted. The Brightwave Hemosep autotransfusion machine can do this – and its prototyping costs have been cut by 96 percent via 3D printing.

British architecture school graduate Jack Munro has found a way to make a building material using one of the few materials from cattle that currently goes to waste – blood.
