New ‘self-healing’ gel makes electronics more flexible

Researchers have developed a first-of-its-kind self-healing gel that repairs and connects electronic circuits, creating opportunities to advance the development of flexible electronics, biosensors and batteries as energy storage devices.

Visualizing atoms of perovskite crystals

Researchers conduct the first atomic resolution study of perovskites used in next generation solar cells.

Dutch children learn about life and death through lion dissection

Until today, the most peculiar thing I’d heard about Denmark was that parents leave their children to sleep outside in subzero temperatures — something that would get you arrested in the United States, if not put on a government watch list. But there’s something else Denmark does very differently when it comes to child-rearing: public dissections. N0 — not dissecting the children! Come on! Two years ago, a zoo in Copenhagen decided to kill a healthy young giraffe that was deemed unfit for breeding. Afterward, the zoo held a dissection, invited the public to watch the process, and then fed Marius the giraffe to some nearby lions. The world hates little more than an animal meeting its untimely death, and an outpouring of outrage…

Stormy weather ahead for wind farms?

Researchers will study the vibrations of wind turbines at a large Chilean wind farm along with health impacts on nearby residents. The goal is to make wind turbines more acceptable. Currently, scientists lack sufficient understanding of wind turbines’ noise and best ways to mitigate the effects, they say.

‘Al dente’ fibers could make bulletproof vests stronger and ‘greener’

Bulletproof vests and other super-strong materials could soon become even tougher and more environmentally friendly at the same time with the help of extra firm, or ‘al dente,’ fibers. Researchers report an innovative way to spin high-performance polyethylene fibers from natural fats, such as oils from olives and peanuts.

Shifting winds: An early warning for reduced energy

Chinook winds can precede large shifts in wind power output from wind farms — a challenge for companies seeking to provide a constant stream of green energy to consumers. By establishing a connection between local meteorological events and power grid output, the researchers hope that they may ultimately help grid operators more accurately predict fluctuations in flow and manage the grid accordingly.
