Comment Re:Children with progeria make results inconclusiv (Score 5, Insightful) 70

The core discovery is nice, even if their problem isn't the there : Their clock is normal BUT their cells interpret it incorrectly, so the problem could be found elsewhere, like a bad clock multiplier when overclocking your PC (could result with it being slower or faster).

At least, now you know that the problem is not the "aging flag" itself, but something that's reading it.

Surveillance should be applied, 24/24, on each elected person FIRST, to make sure no corruption is done at this level.

Some police officers are now under such surveillance, and it help their works, and I just hope it'll go much more farther (Google Glass someone?)

We, citizens, should ALWAYS have the last words.

I'm pretty sure it's the exact opposite :

You take the same turn for 30 years now : YOU KNOW IT, so you optimize it a little bit (without thinking of course... it's a natural event here)... optimize it so much than it became inconsistent and risky... optimize it too much and... you know what I mean ;)

Start by reading and testing their 50$ cheapo robot : http://www.societyofrobots.com/

50$ isn't something that will make you broke, and you'll have a quickstart on electronic parts.
Then, if you wanna upgrade, go get an Arduino, and put it in your 50$ robots (now 80$robot ;) )
Them you can upgrade and add parts as you like, and all with a SMALL budget.

HAVE FUN!

I learned so many things with PCTools 2.41e, from formatting (I was a noob really) to hex editing (Removed face-off copy protection, and even created complete hack list for EyeOfTheBeholder lol)...

I have so much memories with this program... and when I tryed the next version, it was so poor and with so less features....

Crushed Silicon Triples Life of Li-Ion Batteries In the Lab 123

Posted by Soulskill from the get-me-a-hammer dept.
derekmead writes "Batteries rule everything around us, which makes breakthroughs a big deal. A research team at Rice says they have produced a nice jump: by using a crushed silicon anode in a lithium-ion battery, they claim to have nearly tripled the energy density of current li-ion designs. Engineer Sibani Lisa Biswal and research scientist Madhuri Thakur reported in Nature's Scientific Reports (it has yet to be published online) that by taking porous silicon and crushing it, they were able to dramatically decrease the volume required for anode material. Silicon has long been looked at as an anode material because it holds up to ten times more lithium ions than graphite, which is most commonly used commercially. But it's previously been difficult to create a silicon anode with enough surface area to cycle reliably. Silicon also expands when it's lithiated, making it harder to produce a dense anode material. After previously testing a porous silicon 'sponge,' the duo decided to try crushing the sponges to make them more compact. The result is a new battery design that holds a charge of 1,000 milliamp hours per gram through 600 tested charge cycles of two hours charging, two hours discharging. According to the team, current graphite anodes can only handle 350 mAh/g."
