It may sound too good to be true, but TU Delft PhD student Ming Ma has found a way to produce alcohol out of thin air. Or to be more precise, he has found how to effectively and precisely control the process of electroreduction of CO2 to produce a wide range of useful products, including alcohol. Being able to use CO2 as such a resource may be pivotal in tackling climate change. His PhD defence will take place on September 14th.
[...] For mitigating atmospheric CO2 concentration, carbon capture and utilization (CCU) could be a feasible alternative strategy to carbon capture and sequestration (CCS). The electrochemical reduction of CO2 to fuels and value-added chemicals has attracted considerable attention as a promising solution. In this process, the captured CO2 is used as a resource and converted into carbon monoxide (CO), methane (CH4), ethylene (C2H4), and even liquid products such as formic acid (HCOOH), methanol (CH3OH) and ethanol (C2H5OH).
The high energy density hydrocarbons can be directly and conveniently utilized as fuels within the current energy infrastructure. In addition, the production of CO is very interesting since it can be used as feedstock in the Fischer–Tropsch process, a well-developed technology that has been widely used in industry to convert syngas (CO and hydrogen (H2)) into valuable chemicals such as methanol and synthetic fuels (such as diesel fuel). The figure attached describes these three processes and the way electroreduction of CO2 could potentially close the carbon cycle.

The statement provides evidence of a connection between light drinking and an increased risk of esophageal and breast cancer. Heavy drinkers face a much longer list of risks, including mouth cancer, throat cancer, cancer of the voice box, liver cancer, and colorectal cancer. That's a whole lot of cancers.
"The message is not, 'Don't drink.' It's, 'If you want to reduce your cancer risk, drink less," said Dr. Noelle LoConte, lead author of the statement. "And if you don't drink, don't start." She says this "subtle" take on the issue is somewhat less cautionary than the warnings about smoking. But the message rings the same.
The doctors behind the statement aimed to draw attention to what they view as a public health problem and advocate for a push towards better education and research.
