Submission + - Astronomers observe black hole producing cold, star-making fuel from hot plasma (mit.edu)

baalcat writes: The Phoenix cluster is an enormous accumulation of about 1,000 galaxies, located 5.7 billion light years from Earth. At its center lies a massive galaxy, which appears to be spitting out stars at a rate of about 1,000 per year. Most other galaxies in the universe are far less productive, squeaking out just a few stars each year, and scientists have wondered what has fueled the Phoenix cluster’s extreme stellar output.

Now scientists from MIT, the University of Cambridge, and elsewhere may have an answer. In a paper published today in the Astrophysical Journal, the team reports observing jets of hot, 10-million-degree gas blasting out from the central galaxy’s black hole and blowing large bubbles out into the surrounding plasma.

So, I can buy a unique Pasmo card but I have to use a credit card to charge it? So sure - my name is NOT registered to the Pasmo card, but it IS registered to the card used to charge it, and thus I am once again trackable. Unless I use barter or cash to charge it. Oh wait...

No, you can charge them with cash at any train station.
Using a credit card is optional.

Submission + - Jet strikes drone near Heathrow airport

smooth wombat writes: A British Airways flight Sunday appears to have collided with a drone on a flight bound for London's busy Heathrow Airport in what may be the first such incident involving a major airline.

The flight from Geneva, Switzerland to Heathrow, Europe's busiest hub, is believed to have struck a drone, the London Metropolitan Police said in a statement. The plane landed safely following the incident, which occurred around 12:50 p.m. local time.

"It was only a matter of time before we had a drone strike given the huge numbers being flown around by amateurs who don't understand the risks and the rules," said BALPA flight safety specialist Steve Landells, adding "much more education of drone users and enforcement of the rules is needed to ensure our skies remain safe from this threat."

That is hardly an "open source" camera.

All they have done on the hardware side is stick a bunch of point grey camera units in a circular holder.
Of course it is going to be expensive!

Point grey cameras are indeed convenient for testing, but are not suitable for this at all.
A $15 image sensor results in a ~$300 pointgrey camera (not including a lens, which is needed either way).

It could be made a LOT more inexpensive by actually designing the hardware like they implied.

I had it done in Japan, and instead of giving you Valium they have a young female nurse hold your hands :)

The actual procedure was interesting, but I was nervous about accidentally moving my eye to look at the interesting pattern of flashes (although I know it compensates for movement).

My vision was amaaazing for about a week, but then I started to get really dry eyes.
Now 3 years later my vision is apparently good in focus, but it is usually blurry because my eyes are so dry.
Drops only help for about 5sec.

So it is nice to be able to work etc without glasses/contacts, but at night my vision is terribly blurry unless I can keep my eyes moist.

Make sure you don't have any possible issue with dry eyes before you consider LASIK!

Of course the problem with placebos is that they essentially require lying to the patient. If you are honest and actually tell the patient "it's just a sugar pill" then it's not going to have any affect.

You would think that, but actually there was a study where the patents were TOLD that it was a placebo (and explained what a placebo is) and it still worked (!). I saw it in a documentary on youtube a week or so ago but can't find it now.

Basically, brains are wierd.

I can't comprehend how someone could not enjoy ANY music, music is the fundamental pre-cursor to language, not only is it deeply ingrained into humans but species as diverse as whales and grasshoppers use music to communicate with each other.

Interesting to know that 1-3% are like me.
I will clarify this for you.

I have zero interest in music. I have never bought (or pirated) a CD or mp3 in my life.
Why people are so obsessed with music I can't understand at all.
It's like how some people looove stamp collecting, I don't understand that obsession either.

It's not a DISlike of music, it's just no interest.
Sure some music has a good beat, or a catchy tune, and I won't complain if someone plays music, but I would never actually choose to play music myself.

Besides this I am pretty much the same as everyone else, I'm not autistic or anything.
I'm an engineer, with friends and a girlfriend, hobbies and a good job.
Music just isn't any more interesting to me than bird noises etc.

Submission + - Nvidia G-Sync Technology Preview: Quite Literally A Game Changer (tomshardware.com)

brittlendor writes: If you’re a PC gamer, you're forever faced with this dilemma: Disable V-sync and live with tearing, or turn it on and tolerate annoying stutter? Nvidia promises to make that question obsolete with a variable refresh rate technology it calls "G-Sync". First announced two months ago, the company finally revealed details on Wednesday. In a nutshell, G-Sync allows your monitor and graphics card to run at the same refresh rate, therefore negating both tearing and stuttering. Nvidia aims to integrate G-Sync boards into PC monitors starting in Q1 2014.

Of course, in order to take advantage of G-Sync, you’ll not only need a new monitor that features the technology, but also an Nvidia graphics card, specifically the GeForce GTX 650 Ti Boost and up. Asus is set to ship a 144Hz 1080p model early next year, and Nvidia is already prepared to take G-Sync to 4K. Unfortunately, it doesn’t appear likely that G-Sync will become an industry standard. Nevertheless, the V-sync conundrum has haunted PC gamers for over a decade, so in the ongoing Nvidia versus AMD graphics battle, G-Sync could prove to be a real game changer.

Submission + - UN Mounts Asteroid Defense Plan Following Chelyabinsk Meteor (ibtimes.com)

Philip Ross writes: Astronomers have warned that our planet is long overdue for a defense plan against catastrophic asteroid collisions. When it comes to deflecting Earth-obliterating celestial bodies, short of a superhero capable of punching the approaching rock back into outer space, there is no single force dedicated to stopping cosmic bullies from striking our little blue planet straight in the eye. That’s why the United Nations said it will establish an International Asteroid Warning Group to intercept and divert dangerous asteroids.

Submission + - 3D Printable Food Moves To Chocolate, Someday Whole Meals (computerworld.com)

Lucas123 writes: Avi Reichentall, CEO of 3D Systems, one of the largest consumer 3D printer companies, has already been able to configure his machines to create a variety of confections. Now he says it won't be long before a chocolate printer can rest beside your coffee maker on the kitchen counter. "I want it to be as cool as a Keurig coffee maker," Reichentall told a crowd at the Inside 3D Printing Conference this week in San Jose. "We're going to bring to pastry chefs and confectionaries and bakers a whole range of new sugar printing capabilities. Meanwhile, Pablos Holman, an inventor at Intellectual Ventures Laboratory, said he and other researchers are working to create printers with toner-type cartridges that hold pulverized freeze dried foods. When dispensed, water and heat is added to cook the food and meals are printed one micro-layer at a time. Not only would the printers be able to prepare foods on the spot, but they could add minuscule amounts of various nutrients to foods to make them healthier without effecting taste. Beyond convenience, 3D printable foods would also avoid enormous waste both at grocery stores where tons of spoiled food is tossed regularly, but in households were up to 60% of food is wasted.

I use the stairs when going up to my office in the morning and at lunch.
If there are people there, I do my usual 2 steps at a time, fast pace but not enough to make people look at me funny.
If there's nobody around, I run up as fast as possible, then recover for a min at the top.

At first I couldn't make it all the way running, but I can get up the 6 floors in ~24 seconds now and can breathe normally enough after that people in the office don't notice. It's not that much, but better than nothing.


Submission + - Claim dismissed as Apple can't find one false statement by Amazon (engadget.com)

cathyreisenwitz writes: ""In finding for Amazon, the judge held that Apple failed to identify a single false statement (expressly stated or implied) that Amazon made about the nature, characteristics, or quality of the Amazon Appstore that would deceive customers into thinking it was the same as the Apple App Store — a legal requirement to establish false advertising under federal law. Not a bad way for Bezos to ring in the new year, eh?""

mromanuk writes: It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time. Their technique opens the door to generating negative-Kelvin materials and new quantum devices, and it could even help to solve a cosmological mystery.
