Take a Visual Tour of CyberKnife Radiosurgery ( 36

reifman writes: On June 3rd, I had brain surgery to treat a benign tumor called a meningioma. I knew ahead of time that the surgeon wouldn't be able to remove the entire tumor – its geography extended from my cavernous sinus to the pituitary gland to the left hemisphere of the brain and to my brain stem. I also needed CyberKnife radiation therapy to attempt to mutate the remaining tumor's DNA to stop its growth. Come meet Lenore, my robotic radiosurgeon.

Human DNA Enlarges Mouse Brains 193

sciencehabit writes Researchers have increased the size of mouse brains by giving the rodents a piece of human DNA that controls gene activity. The work provides some of the strongest genetic evidence yet for how the human intellect surpassed those of all other apes. The human gene causes cells that are destined to become nerve cells to divide more frequently, thereby providing a larger of pool of cells that become part of the cortex. As a result, the embryos carrying human HARE5 have brains that are 12% larger than the brains of mice carrying the chimp version of the enhancer. The team is currently testing these mice to see if the bigger brains made them any smarter.

Russia Seeking To Ban Tor, VPNs and Other Anonymizing Tools 215

An anonymous reader writes Three separate Russian authorities have spoken out in favor of banning online anonymizing tools since February 5th, with particular emphasis on Tor, which — despite its popularity with whistle-blowers such as Edward Snowden and with online activists — Russia's Safe Internet League describes as an 'Anonymous network used primarily to commit crimes'. The three authorities involved are the Committee on Information Policy, Information Technologies and Communications, powerful Russian media watchdog Roskomnadzor and the Safe Internet League, comprising the country's top three network providers, including state telecoms provider Rostelecom. Roskomnadzor's press secretary Vadim Roskomnadzora Ampelonsky describes the obstacles to identifying and blocking Tor and VPN traffic as "difficult, but solvable."

Comment vs WebP (Score 5, Insightful) 377

I don't think we should compare BPG with JPEG, since it is very outdated. I wonder how it stacks against WebP - does it also support animation? Better compression? Licenses? Faster encoding/decoding? Browser manufacturer support? I'm all for making web more optimal, because you can never have "fast-enough" bandwidth, especially on a mobile device in bad connection area, but lets compare similar things.


The Guardian Reveals That Whisper App Tracks "Anonymous" Users 180

New submitter qqod writes this story at The Guardian that raises privacy concerns over the Whisper app. "The company behind Whisper, the social media app that promises users anonymity and claims to be the “the safest place on the internet”, is tracking the location of its users, including some who have specifically asked not to be followed. The practice of monitoring the whereabouts of Whisper users – including those who have expressly opted out of geolocation services – will alarm users, who are encouraged to disclose intimate details about their private and professional lives. Whisper is also sharing information with the US Department of Defense gleaned from smartphones it knows are used from military bases, and developing a version of its app to conform with Chinese censorship laws."

Comment Same problem at Wikipedia (Score 1) 60

I am part of the Wikipedia Zero initiative, and we need to ensure that runs on ALL platforms, including the mostly forgotten flip phones with no JavaScript. Which obviously presents the problem of testing. There are some sites (we have an account with one of them) that provides multi-platform testing, but all that means is multiple flavors of Android & IOS... with possibly the latest BB thrown in. Unfortunately, the bigger problem is the older devices, where capabilities were much more varied. One day I hope we can have access to the most commonly used labs testing, including various Nokias, etc. Hoping...

Comment "Physics" is not science (Score 1) 292

"Physics" is a fairly artificial concept of separation of knowledge - after all, knowledge is just one. Our brains, on the other hand, are too tiny to fit all of it in. We started learning about surroundings "midway", e.g. F=ma - basic physical phenomenon, and from there started moving towards the very small (quarks), very large (galaxies), and much more complex - chemistry, biology. I think the discoveries tend to go in waves, and when there is an imbalance of knowledge, the area at the bottom shoots up. For example - enough data accumulated and enough mathematical tools were developed to boost physics and chemistry, which helped with computers, which in turn boosted biology. Next step - exact predictions of social sciences, terraforming, ... Time to travel far far away.

P.S. Even though I couldn't find who was the original author, my physics teacher once told me that when governor visited Franklin's lab, and was shown all the electrical research, he wondered what was the purpose... to which Franklin replied "Physicists will tinker with it for a bit, and later you will start taxing it". It might have been someone else of course, but does not change the point - something gets discovered, and later it becomes ubiquitous in our everyday life.

Comment Only benefits smaller devices (Score 1) 217

The raw speed of the code might actually diminish since the .net runtime could have optimized it better for the specific environment (CPU model, available RAM, phase of the moon, etc). On the other hand, the startup would benefit - no more need to just-in-time compile. Plus there is no need for memory to compile it. On the other hand, the runtime might use some cycles to further optimize code during execution, whereas with this approach the code won't change any further. In any case, great for instant startup, but I suspect conceptually this is not much different from the older binary pre-compiled cached versions of the assemblies.

Thekohser, thanks for the reply, could you point me to the correct info? I only found and that doc is not trivial, so any help explaining your position would greatly help. Where do 49+% go? Is it the same for all non-profits or non-profits in the same sector (if there is such a division). Thank you!
