Researchers have developed a biocompatible ink for 3-D printing using living bacteria

A group of ETH researchers has now introduced a new 3D printing platform that works using living matter. The researchers developed a bacteria-containing ink that makes it possible to print mini biochemical factories with certain properties, depending on which species of bacteria the scientists put in the ink.

Scientists find four big insights into HIV/AIDS that provide hope for finding a vaccine

The sub-Saharan African Network for TB/HIV Research Excellence has been at the forefront of this research and has provided some important insights into how the virus spreads as well as the immune mechanisms that enable some people to control the virus without antiretroviral drugs.

Scientists have developed a baldness treatment that helps grow new follicles

Scientists have found a protein that controls the hair growth and developed a new substance that promotes hair regeneration by controlling the function of the protein. They expect that the newly developed substance will contribute to the development of a drug that not only treats hair loss but also regenerate damaged skin tissues.

Scientists engineered a drug delivery device that can treat glaucoma directly inside the eye

Glaucoma, which affects over 60 million people worldwide, can seem easy to treat: medicated eye drops can be used to ease the buildup of fluid in the eye that underlies the condition. If glaucoma is caught early, eye drops can prevent irreversible blindness.

Researchers developed the first in vivo test that can locate tumours within the body

Researchers refine and run the first in vivo tests that use fluorescent nanotube-based probes to locate specific tumors in the body. The ability to pinpoint them with submillimeter accuracy could improve early detection and treatment of ovarian cancer.

New microscopy technique allows direct tracking of fatty acids after they’ve been absorbed into living cells

Researchers have developed a new microscopy technique that allows for the direct tracking of fatty acids after they’ve been absorbed into living cells. What they found using this technique could have a significant impact on both the understanding and treatment of obesity, diabetes and cardiovascular disease.

Scientists discovered that fish oil component preconditions vision cells to survive future injury

Scientists discovered that a component of fish oil not only protects cells critical to vision from potentially lethal initial insults, but also from those that occur in the future. The study showed that the omega-3 fatty acid, DHA, and its derivatives ‘precondition’ photoreceptor and retinal pigment epithelial (RPE) cells to survive.
