WASHINGTON — A substantial portion of basic medical research goes someplace to expire without ever seeing clinical daylight, but the last day of TERMIS 2014, sponsored by the Tissue Engineering and Regenerative Medicine International Society (TERMIS; San Ramon, California) highlighted some ingenious technological developments, some of which will surely find a place in routine use. One of these innovations is a method for inserting synthetic circuits into individual cells, but a British scientist also explained how low-energy infrared light can be used to manipulate cells in a presentation titled in part "holographic optical tweezers."
