The eternal ebb and flow of tides — 24 x 7 x 365 — makes them a dependable source of energy, but how to harness all that, especially in shallow water? Shreyas Mandre and colleagues at Brown have developed an efficient water wing and optimized its performance with a “secret sauce.”

PROVIDENCE, R.I. [Brown University] — When it comes to raw power and absolute reliability, it doesn’t get much better than the tides. That’s why tidal power is such an attractive option as a renewable form of energy. But designing a device to gather tidal energy in shallow water, where the ebb and flow move fastest and the energy potential is highest, has proven problematic. (more…)

Seahorse Heads have a ‘No Wake Zone’ That’s Made for Catching Prey

AUSTIN, Texas — Seahorses are slow, docile creatures, but their heads are perfectly shaped to sneak up and quickly snatch prey, according to marine scientists from The University of Texas at Austin.

“A seahorse is one the slowest swimming fish that we know of, but it’s able to capture prey that swim at incredible speeds for their size,” said Brad Gemmell, research associate at the University of Texas Marine Science Institute, which is part of the College of Natural Sciences. (more…)

One Tiny Electron Could be Key to Future Drugs That Repair Sunburn

COLUMBUS, Ohio – Researchers who have been working for nearly a decade to piece together the process by which an enzyme repairs sun-damaged DNA have finally witnessed the entire process in full detail in the laboratory.

What they saw contradicts fundamental notions of how key biological molecules break up during the repair of sunburn – and that knowledge could someday lead to drugs or even lotions that could heal sunburn in humans. (more…)
