How photosynthesis is inspiring solar power research

by GrrlScientist in Maniraptora

SUMMARY: To meet humanity’s growing energy demands, scientists are taking lessons from plants, which perfected the process of capturing the sun’s rays and transforming that into starch. Might scientists be able to adapt the photosynthetic process pioneered by plants and adapt it to meet human demands? ... Read more »

The Chemistry of Christmas

by Melissa Chernick in Science Storiented

What are the sights, the sounds, the smells, and the textures that you associate with Christmas? Perhaps it is Christmas trees with their lovely green shape, color and wonderful pine smell. Maybe it’s the smells of cooking, the savory smells of turkey or the sweet smell of warm cookies. Or what about all of the cozy feelings you get with big sweaters or a roaring fire? Did you know that there is a lot of chemistry that goes into all of the senses we associate with this holiday?I was browsing t........ Read more »

Electron Paramagnetic Resonance of hair!

by mrsitandspin in Sit and Spin

I wanted to switch gears a bit and do a paper on Electron Paramagnetic Resonance (EPR), also know as Electron Spin Resonance (ESR). The paper for this weeks is

Electron spin resonance (ESR/EPR) of free radicals observed in human red hair: a new, simple empirical method of determination of pheomelanin/eumelanin ratio in hair.

Smart Coatings to Help Clean Up Oil Spills

by dailyfusion in The Daily Fusion

In the wake of recent off-shore oil spills, and with the growing popularity of “fracking”—in which water is used to release oil and gas from shale—there’s a need for easy, quick ways to separate oil and water. Now, scientists have developed coatings that can do just that.... Read more »

‘One-Pot’ Switchgrass Pretreatment and Saccharification Process Demonstrated

by dailyfusion in The Daily Fusion

The advantages of the “one-stop” shop have long been recognized in the retailing and services industries. Similar advantages would also be realized for the biofuels industry with the development of a “one-pot” processing system in which sugars could be extracted from biomass and turned into fuels in a single vat. A major step forward in this goal has now been achieved by researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) who repo........ Read more »

The Lovelock Laboratory: A fantasy workplace in the West Country

by Duncan Hull in O'Really?

Former Mancunian James Lovelock runs the kind of a laboratory most scientists can only fantasise about working in as they grind through the humdrum bureaucracy of peer-review and never-ending grant applications. Lovelock is fortunate enough to run a completely independent, self-funded lab located in the beautiful West Country. There’s a fascinating interview with him on The Life Scientific with Jim Al-Khalili where he says lots of interesting things about elocution lessons, nuclear power, cli........ Read more »
