University at Buffalo researchers have developed 3-D printed dentures filled with antifungal medication to better treat oral fungal infections.

Researchers in Japan have built a new optical device no bigger than the edge of a coin. The device includes a photovoltaic cell that is powered by infrared light and emits blue light. Using infrared light allows the device to be implanted several centimeters deep into the body, while the emission of blue light can be used for optogenetic control of brain patterns.

A team of researchers from the University of Toronto has applied a hacker mentality to developing a portable, reconfigurable lab-on-a-chip diagnostic platform and field-tested the system in remote Kenya. Their validated platform can gauge the level of immunity to vaccine-preventable diseases among vulnerable populations.

A team from Northwestern University and University of Florida has developed a new type of electron microscope that takes dynamic, multi-frame videos of nanoparticles as they form, allowing researchers to view how specimens change in space and time.

When humans get bacterial infections, we reach for antibiotics to make us feel better faster. It's the same with many economically important crops. For decades, farmers have been spraying streptomycin on apple and pear trees to kill the bacteria that cause fire blight, a serious disease that costs over $100 million annually in the United States alone.

A cross-like shape helps the electrodes of implantable neurostimulation devices to deliver more charge to specific areas of the nervous system, possibly prolonging device life span, says research published in March in Nature Scientific Reports.

Physicists at MIPT and their British and Russian colleagues revealed the mechanisms leading to photocurrent in graphene under terahertz radiation. The paper published in Applied Physics Letters not only puts a period to a long-lasting debate about the origins of direct current in graphene illuminated by high-frequency radiation but also sets the stage for the development of high-sensitivity terahertz detectors. Such detectors are highly demanded in medical diagnostics, wireless communications and security systems.

Using sunlight for sustainable and cheap production of, for example, medicines. The 'mini-factory' in the form of a leaf that chemical engineers from Eindhoven University of Technology presented in 2016 showed that it is possible. Now the researchers have come with an improved version: their 'mini-factory' is now able to keep production at the same level, irrespective of the variation in sunlight due to cloudiness or time of the day. As a result, this boosts the average yield by about 20 percent.
