New X-ray Technique Illuminates Reactivity Of Environmental Contaminan
A chemical reaction can occur in the blink of an eye. Thanks to a new analytical method, scientists can now pinpoint, at the millisecond level, what happens as harmful environmental contaminants such as arsenic begin to react with soil and water under various conditions. Super Blackcurrants With Boosted Vitamin C
Scientists are working to boost the vitamin C content of blackcurrants in a move that would be a major benefit to consumers and farmers. Researchers have tracked the production and storage of vitamin C in blackcurrant bushes and are now studying the factors that determine the levels of the nutrient. Working out how to boost the vitamin C content of blackcurrants would help to promote consumption of the vital nutrient and also improve juice quality. Nerdy passwords, secure and memorable
WARNING: Do not simply use the formula of a common chemical without obfuscating it in some way. It could be dictionary cracked very easily if you do.Coming up with a secure password that cannot be bruteforce or dictionary attacked but that is easy to remember is quite troubling. So, here’s the nerdiest approach yet.Think of [...]Nerdy passwords, secure and memorable is a post from: Sciencebase Science Blog Use Of Stone Hammers Sheds Light On Geographic Patterns Of Chimpanzee
In a finding that challenges a long-held belief regarding the cultural spread of tool use among chimpanzees, researchers report that chimpanzees in the Ebo forest, Cameroon, use stone hammers to crack open hard-shelled nuts to access the nutrient-rich seeds. The findings are significant because this nut-cracking behavior was previously known only in a distant chimpanzee population in extreme western Africa and was thought to be restricted by geographical boundaries that prevented cultural spread of the technique from animal to animal.

'Laser Tweezers' Reveal Microscopic Mechanical Properties Of Blood Clo
For the first time ever, using "laser tweezers,"the mechanical properties of an individual fiber in a blood clot have been determined by researchers at the University of Pennsylvania School of Medicine. Their work provides a basis for understanding how the elasticity of the whole clot arises. Moth Joins Battle To Cut Mimosa Down To Size

FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." The Baton Rouge Bus Boycott of 1953: A Recaptured Past
