Hydrogen is a critical component in the manufacture of thousands of common products from plastic to fertilizers, but producing pure hydrogen is expensive and energy intensive. Now, a research team at Princeton University has harnessed sunlight to isolate hydrogen from industrial wastewater. In a paper published Feb. 19 in the journal Energy & Environmental Science,…

Self-Assembling Particles Brighten Future of LED Lighting
Just when lighting aficionados were in a dark place, LEDs came to the rescue. Over the past decade, LED technologies — short for light-emitting diode — have swept the lighting industry by offering features such as durability, efficiency and long life. Now, Princeton engineering researchers have illuminated another path forward for LED technologies by refining…
Stiff and Oxygen-Deprived Tumors Promote Spread of Cancer
When Hippocrates first described cancer around 400 B.C., he referred to the disease’s telltale tumors as “karkinos” — the Greek word for crab. The “Father of Western Medicine” likely noted that cancer’s creeping projections mirrored certain crustaceans, and the tumors’ characteristic hardness resembled a crab’s armored shell. Later, scientists added another attribute: Tumors are hypoxic.…
