Urgent security update


Bad news: A major vulnerability has been disclosed for the technology that powers encryption across the majority of the internet. That includes Tumblr. Our team took immediate action to fix the issue, but you should still take some time to change your password, not only here but on any other sites you visit. 

You should also strongly consider enabling two-factor authentication. It’ll go a long way to ensure that no one besides you can access your account. Thanks, and take care.


Materials scientist John Rogers and his firm MC10 have developed flexible electronic circuits that stick directly to the skin like temporary tattoos and monitor the wearer’s health.

The Biostamp is a thin electronic mesh that stretches with the skin and monitors temperature, hydration and strain.

Rogers suggests that his “epidermal electronics” could be developed for use in healthcare to monitor patients without tethering them to large machines. Not only would this be more convenient, but the results could be more accurate if patients were examined in their normal environment doing usual activities rather than on the hospital ward.

Other applications could include a patch that lets an athlete know when and how much to hydrate for peak performance, or one that tells you when to apply more suncream.

MC10 overcame the rigidity of normal electronic components made from brittle silicon-based wafers by printing them in very small pieces, arranged in wavy patterns.

Earlier versions were applied on an elastomer backing patch, but the latest prototype is applied directly to the skin using a rubber stamp. It can be covered with spray-on bandage available from pharmacies to make it more durable and waterproof enough to withstand sweating or washing with soapy water. It lasts up to two weeks before the skin’s natural exfoliation causes it to come away.

The team are now working on the integration of wireless power sources and communication systems to relay the information gathered to a smartphone.

Other wearable monitoring technology we’ve reported on includes the Nike+ FuelBand and Jawbone UP wristbands that monotor health and fitness, plus a wearable camera that uses sensors and GPS technology to decide which moments of your life are worth photographing.

Hi I'm a freshman in high school, and I want to be a nurse. Do you have any recommendations as to which classes I should take in high school to be better prepared for college?

Load up on science classes!! Try to get some AP psych or any AP class for that matter. Some high schools will let you become a CNA. If you can do that. Otherwise biology, chemistry, and A&P! Good luck! I think it’s awesome that you already know what you want to do!

This is random and hopefully not weirdddd but I was wondering how you got through nursing school. I'm in my first semester now and it is crazy hard and insane any adviceeeeee?!?!

I took it one week at a time. If I thought about all I had to do the whole semester I got overwhelmed and started to panic. I kept up with my readings. And I was in a study group! They were awesome!! We motivated each other!! We stayed together all through school! Good luck! Find a group!
