When you burn or rip off a stretch of skin, your main option right now is to graft some back on from elsewhere on your body. But an effective synthetic replacement skin may not be that far off, thanks to research from Stanford scientists.

The experiments are conducted using fixed equipment (such as treadmills and exercise bikes) in a correctly matched airstream, under conditions which accurately simulate the relative motion through the air of an exercising person. The tests are being conducted with Dr Kevin Gouder's team in the Department’s 10 x 5 wind tunnel, the upper section of which allows the use of human subjects without any flow constraint. The co-leads on the project are Dr George Papadakis (the project's PI) and Professor Denis Doorly.

Remedy: This is another hindsight-based regret that you can’t cure without a time machine. The years, energy and dollars you spent on your degree are sunk costs. You can’t do anything about your past academic track record, but you can identify the areas in which you think you fell short in your college days and figure out how to augment those shortcomings in the present. For example, if you feel you didn’t do enough networking outside of the classroom, you might consider joining an alumni group or make a greater effort to participate in professional associations in your field. If you regret skipping your 8:00 AM managerial accounting class and mourn how useful those concepts would be to you now, check out the continuing ed options at your nearest community college.
