Japan team claims they created functional human liver from stem cells: report
A team of scientists claim they transplanted induced pluripotent stem… Japanese researchers have created a functioning human liver from stemcells, a report said Friday, raising hopes for the manufacture of artificial organs for those in need of transplants. A team of scientists transplanted induced pluripotent stem (iPS) cells into the body of a mouse, where it grew into a small, but working, human liver, the Yomiuri Shimbun said. Stemcells are frequently harvested from embryos, which are then discarded, a practice some people find morally objectionable. But iPS cells -- which have the potential to develop into any body tissue -- can be taken from adults. A team led by professor Hideki Taniguchi at Yokohama City University developed human iPS cells into "precursor cells", which they then transplanted into a mouse's head to take advantage of increased blood flow. Two separate teams, one from the United States and one from Japan, discovered iPS cells in 2006.

'Vocal Fry' Is the Hot New Linguistic Fad Among Women
I am an old, grouchy woman who does voiceovers for a living. So I am more conscious of sound and inflection than most people, I suppose. The way young women you reference talk makes me nuts. Not just because it sounds affected, but because in my eyes it infantalizes the girls in question. Someone who adopts this way of speaking is hopefully not very bright, because if she IS bright and elects to adopt this kind of speech..well, she sounds like a not very bright, whiny creature, who needs to be coddled and placated and who clearly has some kind of rash on her bottom. You ain't never going to hear that speech pattern emanating from the Presidential podium for example. You WILL hear it from the girl who does your nails, the girl who has a married Mafiosi boyfriend, and the girl who is assistant manager at Forever-21.
The Phone Stack
We usually take a pretty hard line against phones at dinner, but a new trick just popped up that gives us hope for the future. It’s called a phone stack, and it’s a buzzing, flashing reminder of every phone-etiquette rule the world seems to have forgotten. It works like this: as you arrive, each person places their phone facedown in the center of the table. (If you’re feeling theatrical, you can go for a stack like this one, but it’s not required.) As the meal goes on, you’ll hear various texts and emails arriving… and you’ll do absolutely nothing. You’ll face temptation—maybe even a few involuntary reaches toward the middle of the table—but you’ll be bound by the single, all-important rule of the phone stack. Whoever picks up their phone is footing the bill. It’s a brilliant piece of social engineering, masquerading as a bar game. But if, after the third ring, you decide your call is more important than your lunch tab, we’re sure your friends won’t object.
LSD Inventor's Remarkable Letter to Steve Jobs
When Apple’s late guru, Steve Jobs, said in 2005 that "doing LSD was one of the two or three most important things I have done in my life," he caught the attention of another guru and inventor who lived 6,000 miles away in Switzerland. Albert Hofmann was a scientist working for Sandoz chemicals in Basel in 1938 when he first synthesized lysergic acid diethylamide, AKA LSD. That same year, he also became the first person to ingest acid and experience its peculiar psychedelic effects. In 2007, Rick Doblin, director of the Multidisciplinary Association of Psychedelic Studies (MAPS) in Santa Cruz, called Hofmann—who had just celebrated his 101st birthday—and told him that Jobs was a fan of the drug. So Hofmann sent a personal handwritten note, from one revolutionary inventor to another, wondering if the Apple founder might want to support a new study of "LSD-assisted psychotherapy in subjects with anxiety associated with life-threatening illness."
