In fruit flies, a biochemical called tyramine seems to be responsible for such drug responses, and Dr Hirsh thinks that tyramine regulation is the chemical link between these two very different processes.
Kutcher, who was a biochemical engineering major at Iowa before dropping out, was an investor in Skype (the second time around when it was spun out of eBay), getting recruited by Marc Andreessen.

Although the proposition of four types is not new (Plato, Jung), her nomenclature and their biochemical foundation represent a frontier of relationship science, albeit one that is thinly populated and open to flanking attack.
Mr Gazzaniga appeals, not wholly convincingly, to quantum mechanics and complexity to provide escape routes from the conclusion that, because the body is a biochemical system, what happens in the mind is physically determined.
In many ways, it seems that the vaccine may help with smoking cessation, but more practically along with medications and other cognitive based therapies to help reinforce any gains made by the vaccine on a biochemical level.
The damage spreads to surrounding tissue over the next several hours, hastened by a toxic biochemical cascade.
Prey cells that stuck to bait cells turned blue through a complex biochemical process which was also engineered into them.
Ellison and Bertarelli, the heir to a Swiss biochemical fortune, had been quarreling in court long before their yachts faced off in open waters.
The researchers then used a few more biochemical tricks to crystallise out the protein fragments, and analyse them, eventually producing an extremely detailed three-dimensional atomic map.
Unlike Pfizer, which is testing a wide array of cancer drugs, Friend is focusing on medicines that are related in a few, distinct biochemical pathways.
And he seems to have realised what biologists themselves are only starting to come to grips with that biology is basically a software problem in which biochemical pathways stand in for computer algorithms.
ECONOMIST: Yes, Bill Gates really does think he can cure the world
Cox-2 inhibitors, developed with much hype in the mid-1990s, block an enzyme called cyclooxygenase-2, in so doing shutting off a wide-reaching cascade of biochemical signals that take the form of fats called prostaglandins.
He carried the baton a bit farther by looking at the biochemical changes involved in the formation of memory first (because such experiments are unethical in people) in sea slugs, and then in mice.
Her work will focus on a high throughput platform for label-free detection of biochemical pathways involved in the differentiation of stem cells.
Please note that the above is a rather vast oversimplification of the physical, neurological and biochemical considerations that have to be made.
Or think about sneakers and athletic apparel that are being made intelligent, with capabilities to mine your sweat for insights into your biophysical and biochemical well-being or warn of the possibility of a potential health problem or nutritional deficiency.

These sites work as switches activating one biochemical pathway when they encounter the chemical signals of infectious agents, and a different one when they meet with those of an interloper organ.
Regardless of the biochemical details, the most intriguing thing Dr Baker's result provides is a new way of thinking about how to slow the process of ageing and one that works with the grain of nature, rather than against it.
ECONOMIST: A way to counteract part of the process of growing old
Of particular interest is an antibody for a growth factor called IGF-1 that is related to the same biochemical pathway Erbitux hits.
With this project she will develop a new label-free biomolecular detection method, based on a technique called Plasmon Resonance Energy Transfer (PRET), to monitor biochemical pathways involved in the differentiation of stem cells.
The next trick, which Exxon's money will help pay for, is to tweak the biochemical pathway that makes the algal oil (which is known, technically, as a triglyceride, and has oxygen atoms in it as well as carbon and hydrogen) so that the oxygen-containing parts of the molecules are snipped off and a pure hydrocarbon is left.
Unlike Codexis, which deals in purified enzymes, Amyris employs a technique called synthetic biology, which turns living organisms into chemical reactors by assembling novel biochemical pathways within them.
But a group of biologists led by Eivind Hovig of the Norwegian Radium Hospital in Oslo has managed to find a way to speed the process up, by linking together the vast quantities of disconnected biochemical information that have already been published.
