Scientists have produced a tomato enriched in the Parkinson’s disease drug L-DOPA in what could become a new, affordable source of one of the world’s essential medicines.

The development of the genetically modified (GM) tomato has implications for developing nations where access to pharmaceutical drugs is restricted.

This novel use of tomato plants as a natural source of L-DOPA also offers benefits for people who suffer adverse effects — including nausea and behavioral complications — of chemically synthesised L-DOPA .

Tomato — was chosen as a widely cultivated crop that can be used for scaled up production a...

A stretchable system that can harvest energy from human breathing and motion for use in wearable health-monitoring devices may be possible, according to an international team of researchers, led by Huanyu “Larry” Cheng, Dorothy Quiggle Career Development Professor in Penn State’s Department of Engineering Science and Mechanics.

The research team, with members from Penn State and Minjiang University and Nanjing University, both in China, recently p...

Researchers have developed a potential new treatment for the eye disease glaucoma that could replace daily eye drops and surgery with a twice-a-year injection to control the buildup of pressure in the eye. The researchers envision the injection being done as an office procedure that could be part of regular patient visits.

The possible treatment, which could become the first non-drug, non-surgical, long-acting therapy for glaucoma, uses the injection of a natural and biodegradable material to create a viscous hydrogel — a wa...

Researchers at Oregon State University are making key advances with a new type of optical sensor that more closely mimics the human eye’s ability to perceive changes in its visual field.

The sensor is a major breakthrough for fields such as image recognition, robotics and artificial intelligence...
