Graphene may be versatile, but there’s one thing it’s not all that good at – dispersing in water. Now, researchers at Umeå University have found a relatively simple way to do it. Graphene oxide is a different form of the material that can make for stable water dispersion, which can then be used as a kind of graphene paint.

Graphene is essentially a two-dimensional sheet of carbon atoms, arranged in a hexagonal pattern. This deceptively simple material has a range of useful properties – it’s incredibly lightweight, thin and flexible, but still strong. It’s also an excellent conductor of electricity and heat, so it’s turning up in everything from electronics to water filters to clothing.

Ideally, one useful way to get graphene into the right configurations could invol...

A team of Clemson University College of Science researchers, in collaboration with international colleagues, has reported the first definitive detection of a relativistic jet emerging from two colliding galaxies — in essence, the first photographic proof that merging galaxies can produce jets of charged particles that travel at nearly the speed of light.

Furthermore, scientists had previously discovered that these jets could be found in elliptical-shaped galaxies, which can be formed in the merging of two spiral galaxies...

Scientists have developed a precise, nanotechnology-based treatment to alleviate the pain and fertility problems associated with endometriosis, a common gynecological condition in women of childbearing age.

Research led by Oleh Taratula of the Oregon State University College of Pharmacy and Ov Slayden of the Oregon National Primate Research Center at Oregon Health & Science University used photo-responsive nanoparticles loaded with dye to find and remove the lesions associated with the disorder.

The endometrium is the innermost layer of the uterus, and endometriosis occurs when endometrium-like tissue forms lesions outside of the uterine cavity—usually involving the ovaries, the fallopian tubes and the tissue lining the pelvis.

On rare occasions, en...

Tiny biohybrid robots on the micrometer scale can swim through the body and deliver drugs to tumors or provide other cargo-carrying functions. The natural environmental sensing tendencies of bacteria mean they can navigate toward certain chemicals or be remotely controlled using magnetic or sound signals.

To be successful, these tiny biological robots must consist of materials that can pass clearance through the body’s immune res...
