Tricking Algae's Biological Clock Boosts Production Of Drugs And Biofuels
2013-11-07 13:15:53

Vanderbilt University Tricking algae's biological clock to remain in its daytime setting can dramatically boost the amount of valuable compounds that these simple marine plants can produce when they are grown in constant light. That is the conclusion of a "proof of concept" experiment described in the Dec. 2 issue of the journal Current Biology. The study found that when the biological clocks of cyanobacteria (blue-green algae) were stopped in their daylight setting, the amount of...

Knowing who your doctor is — and a couple of facts about that person — may go a long way toward improving patient satisfaction, according to a Vanderbilt study in the Journal of Orthopaedic Trauma. Faced with the knowledge that between 82 percent and 90 percent of medical patients are unable to correctly name their treating physician following inpatient admission, orthopaedic trauma surgeon Alex Jahangir, M.D., and his Vanderbilt colleagues studied the effects of giving a randomized...

Supercapacitor Stores Electricity On Silicon Chips
2013-10-23 08:54:48

Vanderbilt University Solar cells that produce electricity 24/7, not just when the sun is shining. Mobile phones with built-in power cells that recharge in seconds and work for weeks between charges. These are just two of the possibilities raised by a novel supercapacitor design invented by material scientists at Vanderbilt University that is described in a paper published in the Oct. 22 issue of the journal Scientific Reports. It is the first supercapacitor that is made out of...

Surgeons’ Sense Of Touch During Minimally Invasive Surgeries Restored
2013-10-16 10:16:33

[ Watch The Video: Palpation Capsule ] Vanderbilt University A small, wireless capsule has been developed that can restore the sense of touch that surgeons are losing as they shift increasingly from open to minimally invasive surgery. During open surgery, doctors rely on their sense of touch to identify the edges of hidden tumors and to locate hidden blood vessels and other anatomical structures: a procedure they call palpation. But this practice is not possible in minimally invasive...

Area Of The Brain That Creates Illusory Shapes And Surfaces Discovered By Scientists
2013-10-01 11:10:48

Vanderbilt University The logo of the 1984 Los Angeles Olympics includes red, white and blue stars, but the white star is not really there: It is an illusion. Similarly, the "S" in the USA Network logo is wholly illusory. Both of these logos take advantage of a common perceptual illusion where the brain, when viewing a fragmented background, frequently sees shapes and surfaces that don't really exist. "It's hallucinating without taking drugs," said Alexander Maier, assistant...

Size Matters In Nanocrystals' Ability To Adsorb And Release Gases
2013-08-07 08:02:53

Vanderbilt University More efficient catalytic converters on autos, improved batteries and more sensitive gas sensors are some of the potential benefits of a new system that can directly measure the manner in which nanocrystals adsorb and release hydrogen and other gases. The technique, which was developed by Vanderbilt University Assistant Professor of Chemical and Biomolecular Engineering Rizia Bardhan, is described in a paper published online Aug. 4 by the journal Nature Materials....


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
