Soils offer new hope as carbon sink

...ar Agricultural Institute. Trials of agrichar - a product hailed as a saviour of Australia's carbon-depleted soils and the environment - have doubled and, in one case, tripled crop growth when applied at the rate of 10 tonnes per hectare. Agrichar is a black carbon byproduct of a process called pyrolysis...

...rent byproducts,” including levulinic acid, making product purification expensive and uncompetitive with petroleum-based chemicals. Zhang, lead author and former post doc Haibo Zhao, and colleagues John Holladay and Heather Brown, all from PNNL, were able to coax HMF yields upward of 70 percent from gluco...

In nature, proteins sweep up nanoparticles

...ater-filled mine. The sulfide is a metabolic waste product of bacteria that thrive in the oxygen-free mine. Once the sulfide is released into the watery environment, it readily combines with metals, in this case zinc, to form nano-sized biominerals that measure about one-billionth of a meter in diameter. ...

Turning green gunk to gold, anti-cancer gold

...Developing an efficient synthetic route to natural product compounds and their analogs is often an essential step in drug development. With drugs such as penicillin and tetracycline, it can easily be done, but cryptophycins present more of a challenge. Sherman's team realized that with all cryptophycins, the...
