Some exciting news, as reported by the Wall Street Journal, might make you glad that human blood is a renewable resource: "Giving old mice blood from young ones <a>makes them smarter and improves such functions as exercise capacity</a>, according to reports from two research teams that point to new ways to study and potentially treat diseases of aging. In one study, researchers at Stanford University and the University of California, San Francisco found that blood transfusions from young mice reversed cognitive effects of aging, improving the old mice's memory and learning ability. The report was published Sunday in the journal Nature Medicine. Two other reports appearing in Science from researchers at Harvard University found that exposing old mice to a protein present at high levels in the blood of young mice and people improved both brain and exercise capability. An earlier report by some of the same researchers linked injections of the protein to reversal of the effects of aging on the heart. ... What isn't known from all this research, said Buck Institute's Dr. [Brian] Kennedy, is whether young blood might also increase the life span of mice and, if so, what such implications for humans might be."Read Replies (0)

writes "I've had a series of interviews with a late-term startup (approx. 300 employees) and I think there is a good chance they will make me an offer. The technology is great, my skills and interests are a good fit for the position, I think the company has a promising future, and I like they team. Frankly I'm damn excited about it, more so than for any job in my career. However, I'm worried about what could euphemistically be called 'cultural' issues. I'm a few years over 40, with a wife and kids, and all of the engineers at the company seem to be at least 10 years younger than I am. Being at the company's office gives me a distinct old guy at the club feeling.
I don't think the overall number of hours the team works is more than I could handle, but the team does a lot of young-single-guy-at-a-startup group activities (rent-a-limo-and-go-clubbing night, weekends in Tahoe, Burning Man, in-office happy hour) that I wouldn't want or be able to participate in; I need to be home with my family for dinner most nights and weekends and so on. I'm wondering if anyone else has had the experience of working at a startup with, or as, an older programmer, and how it worked out?"Read Replies (0)

From Motherboard comes this description of what may
turns out to be the newest entry on the periodic table,
newly synthesized element 117
, created by researchers at the GSI Helmholtz Centre for Heavy Ion Research of Darmstadt, Germany, and described in results published this week in Physical Review Letters. From the article:"Element 117 has been temporarily given the very literal name ununseptium (one-one-seven in Latin), and will only honored with a real name once the the International Union of Pure and Applied Physics and Chemistry (IUPAPC) confirms its synthesis at the GSI accelerator. Ununseptium is 40 percent heavier than lead, making it on par with the heaviest atoms ever observed. ... Its properties seem to confirm that the existence of the so-called “island of stability”—a theory suggesting that the half-lives of superheavy isotopes will lengthen as their atomic numbers increase further away from uranium. Any element with an atomic number greater than 103 is considered superheavy (or in the 'transactinide class,' if you prefer the scientific jargon). Transactinides can only be observed artificially in a laboratory, and synthesizing them is no easy task."
Note: that "real name" process isn't a mere formality; just a few years ago, another attempt to synthesize a 117th element looked promising enough to be declared done
, but could not be confirmed with the IUPAPC's tests.Read Replies (0)

writes "Swype is a popular third-party keyboard for Android phones (and also available for Windows phones and other platforms). It's currently the second-most-popular paid keyboard in Google Play (behind SwiftKey), and the 17th highest of all paid apps. Recently, users have discovered that it's been accessing location data extremely frequently, making almost 4000 requests per day, or 2.5 requests per minute. The developers claim that this is to facilitate implementation of 'regional dialects,' but cannot explain why such frequent polling is required, or why this still occurs if the regional function is disabled. Some custom ROMs such as Cyanogenmod can block this tracking, but most users would be unaware that such tracking is even occurring."
Readers in the linked thread don't all seem to see the same thing; if you are a Swype user, do you see thousands of location requests, none, or something in between?Read Replies (0)
