‘Nanoscoops’ – New Nanomaterial Could Spark Next Generation of Rechargeable Batteries

nanoscoops

The material, called a “nanoscoop” because it resembles a cone with a scoop of ice cream on top, is shown in the above scanning electron microscope image.

An entirely new type of nanomaterial developed at Rensselaer Polytechnic Institute could enable the next generation of high-power rechargeable lithium (Li)-ion batteries for electric automobiles, as well as batteries for laptop computers, mobile phones, and other portable devices.

Hydrogenase: Self-sufficient Organic Airship

Hydrogenase

Vincent Callebaut’s latest project, Hydrogenase, aims to create a self-sufficient organic airship.   This conceptual transport system would be comprised of airships that produce biofuel from seaweed.  The project draws its inspiration from nature, as well as from the qualities of its materials and its self-manufacturing processes.  (pics)

I used to be a weather idiot. When it was going to rain, I usually found out by getting wet or by seeing everyone else holding an umbrella or rain coat on public transportation. I wanted something that informed me when it was going to rain (but not something that I had to look for). I wondered if there was a text message alert system for when it rained…

‘Cherry’ figure. Note that red organisms predominate, but black fungus is also present.

While some rock art fades in hundreds of years, the “Bradshaw art” remains colourful after at least 40,000 years.

Jack Pettigrew of the University of Queensland in Australia has shown that the paintings have been colonized by colorful bacteria and fungi.

These “biofilms” may explain previous difficulties in dating such rock art…

Is your brain aware of more than the time right now?

Researchers have found evidence for “chronesthesia,” which is the brain’s ability to be aware of the past and future, and to mentally travel in subjective time. They found that activity in different brain regions is related to chronesthetic states when a person thinks about the same content during the past, present, or future…
