Who knew we’d be such grumpy (but NOT old!) men and women?

by Doug Keene in The Jury Room

You probably intuited this already but age is simply not settling well on our largest generation. From the exuberance of youth (“don’t trust anyone over 30”) to the contemplation of approaching 65—Boomers feel anxious about their futures. They are afraid they will outlive Medicare.  But that isn’t all that is vexing the Boomers. A recent [...]

New Recipe for iPS Cells

by Sanford- Burnham in Beaker

Generating iPS cells can be an arduous task. Reprogramming differentiated adult cells into iPS cells requires so many steps and so much time that the efficiency rate is very low – you might end up with only a few iPS cells even if you started with a million skin cells. So a team set out to improve the process. In a paper published February 1, 2011 in The EMBO Journal, they uncovered microRNAs (miRNAs) that are important during reprogramming and exploited them to make the transition from skin c........

Use and abuse on the web

by David Bradley in Sciencetext

Analysing user statistics across websites is an issue that often comes under scrutiny from privacy advocates worried that marketing companies are exploiting their personal data to track their behaviour and target them with advertising. The issue is, of course, a double-edged sword. Many of us would prefer that our online behaviour is not being monitored [...]Post from: David Bradley's Sciencetext Tech TalkUse and abuse on the web

Employability viewpoints

by David Winter in Careers - in Theory

In my last posting about the E word I focused on various models of employability (the fun bit in my geeky world!).

Bribing kids to eat their greens really does work

by BPS Research Digest in BPS Research Digest

Try bribing him with a sticker
Some experts have warned that bribing children to eat healthy foods can be counter-productive, undermining their intrinsic motivation and actually increasing disliking. Lucy Cooke and colleagues have found no evidence for this in their new large-scale investigation of the issue. They conclude that rewards could be an effective way for parents to improve their children's diet. '...rewarding children for tasting an initially disliked food produced sustained increas........
