Artificial

Tiny robots could serve useful functions, but shrinking actuators has proven challenging. Now researchers at the University of Wollongong have made artificial muscles that surpass your puny natural ones, inspired by the “supercoiling” of DNA strands.

A newfound understanding around the intricate architecture of lobster underbellies has provided MIT engineers with a model for a tough and stretchy new hydrogel, which features great durability and resistance to tearing.

It may be a bit gross, but mucus plays a key role in our bodies. Now, an MIT team has managed to create an artificial version of the stuff, and shown that it’s an effective antimicrobial – even more so than real mucus.

Heart failure often requires a transplant of the whole organ. Now scientists at EPFL have developed an artificial aorta that can help pump blood, taking some of the pressure off the heart to reduce or even eliminate the need for a transplant.

Parkinson’s disease is characterized by clumps of misfolded proteins accumulating and killing brain cells. Johns Hopkins researchers have developed an artificial enzyme that may stop these clumps from spreading, providing a new potential treatment.

Spanish researchers have created a new potential treatment for age-related macular degeneration, which is currently untreatable – a biohybrid artificial retina, made of silk and loaded with new human cells that can integrate and repair the damage.

Scientists have successfully bridged the gap between organic and artificial. A team has created biohybrid synapses that let living cells communicate with electronic systems, not with electrical signals but with neurotransmitters like dopamine.

The human eye is incredibly complex, so it's very hard to reverse engineer. Now researchers have unveiled the world’s first 3D artificial eye, which can not only outperform other devices but has the potential to see better than the real thing.

Researchers have created synthetic red blood cells that have all of the useful properties of the real thing, plus a few new tricks. These new cells could be put to work carrying oxygen or drugs through the body, sensing toxins, and other tasks.

Photosynthesis is one of nature’s most useful chemical reactions, so scientists often try to mimic it. Researchers have now developed a new way to make hybrid synthetic-living cells that can use photosynthesis to clear carbon dioxide from the air.

Researchers at Rice University have built a simple new solar-powered device that can create hydrogen for fuel by splitting water. It's similar to other “artificial leaf” designs but the team says it’s self-sufficient and relatively cheap to produce.

The body protects itself from invading viruses and bacteria using antibodies, but when a new threat emerges it takes time for the body to produce new ones. A new system from Berkeley Lab should speed up the discovery of new artificial antibodies.
