Fine-Structure Constant Maybe Not So Constant 105

Posted by samzenpus from the variety-is-the-spice-of-life dept.
Kilrah_il writes "The fine-structure constant, a coupling constant characterizing the strength of the electromagnetic interaction, has been measured lately by scientists from the University of New South Wales in Sydney, Australia and has been found to change slightly in light sent from quasars in galaxies as far back as 12 billion years ago. Although the results look promising, caution is advised: 'This would be sensational if it were real, but I'm still not completely convinced that it's not simply systematic errors' in the data, comments cosmologist Max Tegmark of MIT. Craig Hogan of the University of Chicago and the Fermi National Accelerator Laboratory in Batavia, Ill., acknowledges that 'it's a competent team and a thorough analysis.' But because the work has such profound implications for physics and requires such a high level of precision measurements, 'it needs more proof before we'll believe it.'"

Autism Diagnosed With a Fifteen Minute Brain Scan 190

Posted by samzenpus from the 15-minutes-definitely-15-minutes dept.
kkleiner writes "A new technique developed at King's College London uses a fifteen minute MRI scan to diagnose autism spectrum disorder (ASD). The scan is used to analyze the structure of grey matter in the brain, and tests have shown that it can identify individuals already diagnosed with autism with 90% accuracy. The research could change the way that autism is diagnosed – including screening children for the disorder at a young age."

So, if I understand you right, you're saying the conversation goes like this:

"I don't really want to be talking to my 8-year-old about sex."

"Well, too bad. You should, and we're calling ourselves the Sex Party."

"Wow, you totally changed my mind!"

Um, yeah... not so much. This logic is a lot like atheists calling religious people stupid and expecting that to convert them to atheism.

You know, I know this is in the context of a business, but if you're going to name your political party the Sex Party, do you even stop and think about it? Are they allowed to run ads during prime time? Are you going to have 8-year-old asking, "Daddy, what does sex mean?" I'm not sure I'd vote for a party that put me through that kind of hassle.

First Halophile Potatoes Harvested 117

Posted by timothy from the integrated-dill-is-the-next-step dept.
Razgorov Prikazka writes "A Dutch-based company from Groningen is trying to create a potato race that is able to survive in a saline environment. The first test-batch was just harvested (English translation of Dutch original) on the island Texel and seem to be in good shape. The company states that rising sea-levels will create a demand for halophile crops. I do wonder if one still has to put salt on ones potatoes when they are grown in salt water."

Retrieving a Stolen Laptop By IP Address Alone? 765

Posted by kdawson from the schooling-the-law dept.
CorporalKlinger writes "My vehicle was recently burglarized while parked in a university parking lot in a midwestern state. My new Dell laptop was stolen from the car, along with several other items. I have no idea who might have done this, and the police say that without any idea of a suspect, the best they can do is enter the serial number from my laptop in a national stolen goods database in case it is ever pawned or recovered in another investigation. I had Thunderbird set up on the laptop, configured to check my Gmail through IMAP. Luckily, Gmail logs and displays the last 6 or 7 IP addresses that have logged into your account. I immediately stopped using that email account, cleared it out, and left the password unchanged — creating my own honeypot in case the criminal loaded Thunderbird on my laptop. Sure enough, last week Gmail reported 4 accesses via IMAP from the same IP address in a state just to the east of mine. I know that this must be the criminal who took my property, since I've disabled IMAP access to the account on all of my own computers. The municipal police say they can't intervene in the case since university police have jurisdiction over crimes that take place on their land. The university police department — about 10 officers and 2 detectives — don't even know what an IP address is. I even contacted the local FBI office and they said they're 'not interested' in the case despite it now crossing state lines. Am I chasing my own tail here? How can I get someone to pay attention to the fact that all the police need to do is file some RIAA-style paperwork to find the name associated with this IP address and knock on the right door to nab a criminal and recover my property? How can I get my laptop back — and more importantly — stop this criminal in his tracks?"

Concrete That Purifies the Air 88

Posted by samzenpus from the clean-roads dept.
fergus07 writes "Although much of the focus of pollution from automobiles centers on carbon emissions, there are other airborne nasties spewing from the tailpipes of fossil fuel-powered vehicles. These include nitrogen oxides (NOx). In the form of nitrogen dioxide it reacts with chemicals produced by sunlight to form nitric acid – a major constituent of acid rain – and also reacts with sunlight, leading to the formation of ozone and smog. Everyone is exposed to small amounts of nitrogen oxides in ambient air, but exposure to higher amounts, in areas of heavy traffic for example, can damage respiratory airways. Testing has shown that surfacing roads with air purifying concrete could make a big contribution to local air purity by reducing the concentration of nitrogen oxides by 25 to 45 percent."
