Nanotube film could replace defective retinas

A promising new study suggests that a wireless, light-sensitive, and flexible nanotube-semiconductor nanocrystal film could potentially form part of a prosthetic device to replace damaged or defective retinas. The film both absorbs light and stimulates neurons without being connected to any wires or external power sources, standing it apart from silicon-based devices used for the same purpose. It has so far been tested only on light-insensitive retinas from embryonic chicks, but the researchers hope to see the pioneering work soon reach real-world human application. Read More

Involuntary eye movement may provide definitive diagnosis of ADHD

If a child who's simply very active is mistakenly diagnosed with Attention Deficit Hyperactivity Disorder (ADHD), they can end up on pharmaceuticals such as Ritalin unnecessarily. The problem is, it can be quite difficult to determine if someone actually has ADHD, and misdiagnoses are common. Now, however, researchers from Tel Aviv University have announced that analyzing a patient's eye movements may be the key. Read More

Dual-lens camera promises better smartphone photos

Although people may speak about zooming in with smartphone cameras, what they're doing isn't actual "zooming" in the telephoto-lens sense of the word. That's because almost all phone cameras just have a digital zoom, meaning that in order to get in closer on the subject, the phone just enlarges the pixels from the middle of the frame. The result is a grainy, crappy photo. While it is possible to squeeze optical zoom lenses into phones, Tel Aviv University spinoff company Corephotonics has developed a sleeker solution, that utilizes the combined output of two compact lenses.

Springy fibers developed to mend hearts

When a heart attack occurs, the resulting dead heart tissue is replaced with scar tissue that's incapable of expanding and contracting. This means that the victim is left with a permanently weakened heart. Numerous studies are now looking at ways in which the dead tissue can instead be replaced with functioning cardiac tissue. While most of the lab-grown tissue created so far has used straight fibers as a base, scientists at Tel Aviv University recently had another idea – if the tissue is supposed to expand and contract, then why not make it using springy fibers?

Micro-printing process enables flexible, energy-efficient, biocompatible MEMS

The miniaturization of electronics continues to revolutionize the medical industry with tiny, swallowable devices and minuscule, implanted sensors. Researchers at Tel Aviv University (TAU) have kept the ball rolling with the development of a new micro-printing process that allows the production of flexible and energy-efficient microelectromechanical (MEMS) devices that can be safely used in the human body.

The Porter School of Environmental Studies highlights sustainable building in Israel

A new building at Tel Aviv University features a standalone EcoWall that aims to provide vertical garden space and research facilities for its faculty. The university's Porter School of Environmental Studies (PSES) hopes that its new green building design will not only join the small number of LEED certified buildings in the country, but will also highlight sustainable methodologies for future buildings in Israel.

Gel-coated implants could reverse paralysis caused by nerve damage

When a nerve in the peripheral nervous system is torn or severed, it can take a long time to regenerate – if it does so at all. Depending on the location of the injury, it can leave the affected part of the patient’s body numb and/or paralyzed for years, or even for the rest of their life. Now, however, scientists from Israel’s Tel Aviv University have created a gel and an implant that they claim could vastly aid in the healing of damaged nerves. Read More
