Now, self-healing materials can mimic human skin, healing again and again

...s. In the final steps, the researchers deposit a brittle epoxy coating on top of the substrate, and fill the network with a liquid healing agent. In the researchers’ tests, the coating and substrate are bent until a crack forms in the coating. The crack propagates through the coating until it encounters ...

What animals can tell us about hemorrhage, organ transplants and aging

...t 10 hours? Brine shrimp can lie on the shore like brittle skeletons, but snap back to life when placed in water? Naked mole rats can live for 28 years but their mice cousins live only three? Birds live longer than their ultra-high metabolic rates would predict? Matthew T. Andrews of the University of Min...

Polymers show promise for lab-on-a-chip technology

...l in the semiconductor industry. But LCPs are less brittle and more pliable than silicon, Elias said, adding that LCP devices could be tailored to respond to specific external stimuli, such as temperature changes and UV radiation exposure, which could makes them easier to activate than silicon. And, perhaps ...

Carnegie Mellon researchers discover new cell properties

...but under excessive force the HGPS lamina was more brittle and eventually fractured. "The mutant HGPS lamina is like an egg shell that cracks when excessive pressure or force is exerted against it," Dahl said. "By contrast, normal lamina resembles the rubbery outer shell of a racquetball, which does not br...

Brittle prions are more infectious

... Medical Institute researcher have discovered that brittle prion particles break more readily into new "seeds," which spread infection much more quickly. The discovery boosts basic understanding of prion infections, and could provide scientists with new ideas for designing drugs that discourage or prevent p...

New technology shows our ancestors ate…everything!

...ds, such as leaves, and P. robustus ate more hard, brittle foods. But they also revealed wear patterns suggesting that both species had variable diets. "This new information implies that early humans evolved and altered their diet according to seasonal and other changes in order to survive," said Mark Teafor...

New Scripps Oceanography project to study sediments and ecosystem restoration in Venice lagoon

... studying Venice's lagoon Deheyn will use luminous brittle stars, a cousin species of starfish, to determine whether contaminants in the Venice Lagoon are bioavailable (the amount of contaminants locally present and shown to be accumulated by the organism) and could potentially induce stress on the local eco...
