The integration of conversion processes with anaerobic digestion is key to increase value from agricultural waste, like cocoa pod husks, generated in developing countries. The production of one metric ton of cocoa beans generates some 15 metric tonnes of organic waste that is today underutilized.
Five Rice University engineering laboratories are part of a $33 million national effort to develop a wireless, fully implantable device that can control the body’s circadian clock, halving the time it takes to recover from jet lag and similar disruptions to the body’s sleep/wake cycles.
In this artistic illustration, a user with an NTRAIN implant and its accompanying external hub works in the field. The user inputs a desired time shift (due to shift work or travel across time zones). Based on cues from the body’s physiology, the external hub detects the user’s circadian rhythm and triggers the implant to produce precisely-dosed peptide therapies.

Led by Northwestern University and funded by the Defense Advanced Research Projects Agency (DARPA), the project will blend bioelectronics, synthetic biology and traditional electronics to create a “living pharmacy” that produces the same peptide molecules the body naturally makes to regulate…
For some, their commitment to sustainability is so strong that they’ve have literally made it their business….
Solar energy is terrible for the environment in a number of ways, including the fact that large land areas must be devoted to it. At Forbes, Michael Shellenberger highlights another problem with solar energy: it produces vast quantities of hazardous waste, which are not being adequately dealt with. The last few years have seen growing concern over what happens to solar panels at the end of their life. Consider the following statements: * The problem of solar panel disposal “will explode with full force in two or three decades and wreck the environment” because it “is a huge amoun
