New opportunities from old chemistry in surface science, say Purdue chemists

...face properties. But a drawback to thiols is their intermittent hold on the surface, and the relatively weak chemical bond makes them less attractive for applications that require environmentally durable coatings." Wei's team found that converting amines into DTCs empower them with an ability to grasp gold surfac...

Ophthalmologists and physicists team up to design 'bionic eye'

...nal placement of implants, the system tracks rapid intermittent eye movements required for natural image perception. Vankov, a physicist, designed the projection and tracking system. "In reality, when you think you are fixating to a certain point, your eyes are not steady," Palanker said. "You are microscanning i...

Fasting intermittently reduces cell proliferation, a marker for cancer risk, study finds

Gray wolves maintain the food chain in winter

...ow that shorter winters without wolves will create intermittent food supplies that no longer track the needs of local scavengers. With or without wolves, late-winter carrion abundance will decline with shorter winters. But wolf kills buffer these shortages, providing meals that could determine whether scavengers ...

Bioartificial kidney under study at MCG

...eive dialysis around the clock. With more standard intermittent therapy, patients get several hours of dialysis three to four times a week. Since kidneys are constantly working, it may seem logical that longer dialysis is a better option, but, in fact, the issue has not been scientifically analyzed. This month, ...

Research team discovers first evidence of microbes living in a rock glacier

...iously thought to be devoid of life. Found in an intermittent stream draining from the glacier, the evidence includes traces of dissolved organic material and high levels of nitrates, said Mark Williams, a scientist at Colorado University (CU)-Boulder. The high nitrate levels are believed to be a result of mic...

"Until further studies provide more information on this type of thermal exposure", he said, "teenage boys and young men may consider limiting their use of LC on...

HHS awards $232 million in biodefense contracts for vaccine development
