(PhysOrg.com) -- A team of scientists from the University of Virginia and University of North Carolina in the US have discovered a previously unidentified type of small circular DNA molecule occurring outside the chromosomes in mouse and human cells.
The cover package of this week’s TIME—which should still be on newsstands—detailed the 10 ideas that are changing your life. What kind of ideas, you ask? Well there’s the living alone as the new norm—which I totally get, having mostly lived alone since graduating school, and almost always by choice. There’s the rise of the nones, those Americans who have spiritual inclinations but refuse to belong any specific religious denomination. (I get that, too, as a lapsed Catholic who just read The Posture of Meditation and ordered a yoga cushion off Amazon Prime.) There’s one about food that can last forever, while still tasting good. (For what it’s worth, I have Thai takeout chicken curry in my refrigerator that dates back to the summer.) And there’s black irony, which is different—but not that different—from black comedy.
(PhysOrg.com) -- New measurements announced today by scientists from the CDF and DZero collaborations at the Department of Energy’s Fermi National Accelerator Laboratory indicate that the elusive Higgs boson may nearly be cornered.

IT IS not every day that a piece of science fiction takes a step closer to nuts-and-bolts reality. But that is what seems to be happening to wormholes. Enter one of these tunnels through space-time, and a few short steps later you may emerge near Pluto or even in the Andromeda galaxy millions of light years away.
You probably won't be surprised to learn that no one has yet come close to constructing such a wormhole. One reason is that they are notoriously unstable. Even on paper, they have a tendency to snap shut in the blink of an eye unless they are propped open by an exotic form of matter with negative energy, whose existence is itself in doubt.
Now, all that has changed. A team of physicists from Germany and Greece has shown that building wormholes may be possible without any input from negative energy at all. "You don't even need normal matter with positive energy," says Burkhard Kleihaus of the University of Oldenburg in Germany. "Wormholes can be propped open with nothing."
In the Weekend Interview, Brian Bolduc talks to physicist Michio Kaku, who says that humans are born with the curiosity of scientists but switch to investment banking.
By 2020, the word "computer" will have vanished from the English language, physicist Michio Kaku predicts. Every 18 months, computer power doubles, he notes, so in eight years, a microchip will cost only a penny. Instead of one chip inside a desktop, we'll have millions of chips in all our possessions: furniture, cars, appliances, clothes. Chips will become so ubiquitous that "we won't say the word 'computer,'" prophesies Mr. Kaku, a professor of theoretical physics at the City College of New York. "We'll simply turn things on."
The year is 2032. You have just celebrated your 80th birthday and you have some tough decisions ahead. You can either keep repairing your current body or move into a new one.
The growing of “blank” bodies has become all the rage, and by using your own genetic material, body farmers can even recreate your own face at age 20.
In just 20 years, this is an industry that has moved from the equivalent of Frankenstein’s laboratory to the new celebrity craze, with controversy following it every step of the way.
The combination of a few high profile “accidents” along the way, coupled with those in the religious community who claim that body farmers are playing God, and asking “where does our soul reside?” has given it thousands of top media headlines around the world.
Every person on the planet has a different opinion about this moral dilemma, or whether its safe or dangerous, or whether we should just get better at repairing our existing bodies.
As medical advances continue, and we devise an entirely new range of health-enhancing options, I propose we set a new standard, raising the bar to the highest possible level. I propose we put an end to human death.
In early February, I attended a fascinating conference hosted by the Telecom Council of Silicon Valley. This is a first rate organization and the conference did not disappoint. Many executives were present from various telecom, ...

Yes! Though perhaps not how you might imagine. You can't put more of your brain to work. Your whole brain is working all the time, even when you think you're just being lazy. What you can do is make it work more productively.
There are two proved strategies to make your neural systems more efficient. The first strategy is to focus, which is hard to do. It is quite difficult to force your brain to stay on task and to shut off extraneous thoughts. Yet by concentrating, your brain can muster the neural tools it needs to tackle a complex problem. In fact, intense focus may be one reason why so-called savants become so extraordinary at performing extensive calculations or remembering a slew of facts.
There is a deep connection between the way your brain and a swarm of bees arrives at a decision...
Every decision you make is essentially a committee act. Members chime in, options are weighed, and eventually a single proposal for action is approved by consensus. The committee, of course, is the densely knit society of neurons in your head. And approved by consensus is really just a delicate way of saying that the opposition was silenced.
