To Reduce the Health Risk of Barbecuing Meat, Just Add Beer 179

Posted by timothy
from the honey-this-is-my-medicine dept.
PolygamousRanchKid (1290638) writes "Grilling meat gives it great flavour. This taste, though, comes at a price, since the process creates molecules called polycyclic aromatic hydrocarbons (PAHs) which damage DNA and thus increase the eater's chances of developing colon cancer. But a group of researchers led by Isabel Ferreira of the University of Porto, in Portugal, think they have found a way around the problem. When barbecuing meat, they suggest, you should add beer. The PAHs created by grilling form from molecules called free radicals which, in turn, form from fat and protein in the intense heat of this type of cooking. One way of stopping PAH-formation, then, might be to apply chemicals called antioxidants that mop up free radicals. And beer is rich in these, in the shape of melanoidins, which form when barley is roasted." (The paper on which this report is based, sadly paywalled.)

Synthetic Chromosomes Successfully Integrated Into Brewer's Yeast 107

from the origin-story-for-superyeast dept.
New submitter dunnomattic writes: "Researchers at New York University School of Medicine have achieved a milestone in synthetic biology. A fully synthetic yeast chromosome, dubbed 'synIII,' has successfully replaced chromosome 3 of multiple living yeast cells. The researchers pieced together over 250,000 nucleotide bases to accomplish this feat. Dr. Jef Boeke, the lead author of the study, says, 'not only can we make designer changes on a computer, but we can make hundreds of changes through a chromosome and we can put that chromosome into yeast and have a yeast that looks, smells and behaves like a regular yeast, but this yeast is endowed with special properties that normal yeasts don't have.' Work is underway (abstract) to synthesize the remaining 15 chromosomes."

An anonymous reader writes: "We may not have Saurian Brandy or Romulan Ale, but we'll soon have Klingon Beer. Tin Man Brewing Company in Evansville, Indiana has gotten the OK from CBS to create 'Klingon Warnog,' a Dunkelweizen with 'a modern aroma [of] predominantly mild banana and clove.' It will have an ABV of 5.5%. The Klingon beer will apparently join Vulcan Ale in the Federation of Beer. I wonder what their Prime Directive is."

First Study of the Evolution of Memes On Facebook 56

Posted by Unknown Lamer
from the memepool-goes-to-college dept.
KentuckyFC writes "The way memes evolve on Facebook is startlingly similar to the way genes evolve on Earth. That's conclusion of a team of researchers who have analyzed the evolution of thousands of memes that have appeared more than 460 million times on Facebook. The memes are ideas like: 'No one should die because they cannot afford health care and no one should go broke because they get sick. If you agree please post this as your status for the rest of the day,' which has been copied 470,000 times. However, the meme quickly mutated. A version that included the phrase '[Your Name] thinks that' appeared 60,000 times. And humorous versions appeared too: 'No one should be without beer because they cannot afford one.'

The team analyzed how often variants appeared and how different they were to the original to get a measure of each meme's evolution. It turns out that this evolution follows the same mathematical evolution, called the Yule Process, that genes follow. And there are other similarities too. There is a small but clear preference for variants that are shorter than the original memes. That's analogous to bacteria favoring small genomes because they allow fast replication. And the same advantageous sequences can appear in many different memes, probably transferred by a single individual from one meme to another. This process is analogous to lateral gene transfer in bacteria. There are some differences too. Evolution is a blind process in biology but not in social media there can be a conscious effort to create mutations that will spread more effectively. This leads to some memes evolving with very high replication rates that are not described by the Yule process. The team says the results should provide greater insight into the nature of information transfer in social networks. It also raises the interesting question of how far evolution might go when given a little time to play with memes."

Fake Pub Studies Drinking Habits 118

sciencehabit writes "In a pub on the campus of London South Bank University, you may think you're drinking an ice cold brew, but don't be too sure. A fake pub with barstools, beer pumps, and all the trappings of a real one was built on the university for psychologists to better understand how and why we drink. Hidden cameras and a cheerful staff — who are undercover psychology students — help analyze behavior when customers, or test subjects, pay a visit."

samzenpus writes "Every year companies are willing to dish out big bucks to reach tens of millions of consumers with their Super Bowl ads. With an average price tag of $4 million for a 30-second commercial, this year is no exception. We've seen: beer obsessed frogs, field goal kicking horses, celebrities drinking various beverages, explosions of all sizes, homages to 1984, and day trading babies in the past. Since talking about the commercials has become almost as popular as the game itself, here's a place to do just that. What have you liked and what do you think would have been better left on the cutting room floor."

Ancient Egyptian Brewer's Tomb Found 66

Rambo Tribble writes "Reminding us of beer's pivotal role in the civilization of humankind, the BBC comments on the discovery of an Ancient Egyptian tomb, belonging to the distinguished 'head of beer production' in the Pharaoh's court. From the article: 'Experts say the tomb's wall paintings are well preserved and depict daily life as well as religious rituals. Antiquities Minister Mohamed Ibrahim told the Egyptian al-Ahram newspaper that security had been tightened around the tomb until excavation works are complete.'"

Ford Rolls the Dice With Breakthrough F-150 Aluminum Pickup Truck 521

Posted by samzenpus
from the shiny-new-truck dept.
Hugh Pickens DOT Com writes "USA Today reports that Ford's next F-150 pickup truck will be made mostly of aluminum, instead of steel, in a bid to save weight. It will likely either be hailed as a breakthrough product to buyers who've made F-150 the bedrock of its business or one that draws comparisons to a 'rolling beer can.' The automaker has asked Alcoa, which makes aluminum blast shields for battlefield-bound vehicles, to lend some of its military-grade metal for the automaker's display, according to people familiar with Ford's plans. Ford's sales job will be considerable: The company is eager to demonstrate the toughness of aluminum, which is lighter than steel, to pickup buyers at next month's Detroit auto show. 'This is already the most significant debut at the auto show,' says Joe Langley. 'Everybody's going to be dissecting that thing for a long time, especially since Ford will be taking such a big gamble.' As a transformative product with a potentially troublesome introduction, the new F-150 has drawn comparisons with Boeing Co.'s 787 Dreamliner — an aircraft developed under the company's commercial airplane chief at the time, Alan Mulally, who in 2006 became Ford's chief executive officer. Because of the complicated switch to aluminum from steel in the F-150's body, IHS Automotive estimates Ford will need to take about six weeks of downtime at each of its two U.S. truck plants to retool and swap out robots and machinery. Ford is apparently trying to squeeze more than 700 pounds out of its next generation of pickup trucks. Using aluminum to cut weight would help meet rising fuel economy standards in the United States, which is requiring a fleetwide average of 54.5 miles per gallon by 2025."

The Archaeology of Beer 89

Posted by timothy
from the glog-glog-glog dept.
cold fjord writes with an excerpt from The Atlantic's profile of Dr. Pat McGovern, a biomolecular archaeologist at the University of Pennsylvania Museum of Archaeology and Anthropology, who has what sounds like a fascinating job: decoding ancient clues about what (and how) humans in the distant past were brewing and drinking. "'We always start with infrared spectrometry,' he says. 'That gives us an idea of what organic materials are preserved.' From there, it's on to tandem liquid chromatography–mass spectrometry, sometimes coupled with ion cyclotron resonance, and solid-phase micro-extraction gas chromatography–mass spectrometry. The end result? A beer recipe. Starting with a few porous clay shards or tiny bits of resin-like residue from a bronze cup, McGovern is able to determine what some ancient Norseman or Etruscan or Shang dynast was drinking." The article points out that McGovern has collaborated with the Dogfish Head brewery to reproduce in modern form six of these ancient recipes.

Beer Drinking Networks In Amazon Tribe Help Explain Altruism 157

Posted by samzenpus
from the have-one-on-me dept.
KentuckyFC writes "The Tsimane tribe are hunter-gatherers living in the forested region between the foothills of the Andes and the wetland-savannas of the Llanos de Moxos in Bolivia. They drink beer made from boiled manioc (a type of sweet potato) which they chew and spit into the mix to trigger fermentation. After a week or so, the resultant brew is about 4 per cent alcohol. Now anthropologists studying this tribe say the way they host beer drinking events for each other offers important clues into their culture. At issue is the question of altruism: why people spend considerable time and effort doing favors for others that don't directly benefit them. The answer from studying these beer drinking events is that the favor is quickly returned by the guests in the form of another beer drinking event. This helps to build good relations with neighbors and family. And when the beer drinking invite is not returned, the researchers speculate that this is probably because there is some other favor involved, such as helping to gather or prepare food, suggesting mates or political co-operation."

The Fascinating Science Behind Beer Foam 73

from the ok-now-explain-my-flickering-lights dept.
RenderSeven writes "Science has so far been at a loss to explain why tapping a beer bottle with another causes it to explosively foam over. Thanks to a grant from the Spanish Ministry of Economy and Competitiveness, a research team at the University of Madrid studying fluid mechanics has found the answer with some fascinating slow-motion video. Their soon-to-be-published paper found that tapping the bottle (or shooting it with a laser) causes a series of compression and expansion waves, that generate unstable buoyant plumes, quickly turning most of the liquid into foam. PhysicsBuzz notes that the process is very rapid and nearly unstoppable once started."

White House Official Tracked Down and Fired Over Insulting Tweets 208

from the calls-em-like-he-sees-em dept.
Hugh Pickens DOT Com writes "BBC reports that Jofi Joseph, a senior National Security Council staffer who was a key member of the White House team negotiating on Iran's nuclear weapons program, has been fired ... after a months-long probe into a barrage of tweets that included caustic criticisms of former Secretary of State Hillary Clinton and top NSC officials, especially Ben Rhodes – whom he accused of dodging questions about Benghazi. Joseph, who posted under the now defunct Twitter name @NatSecWonk, gave a lacerating commentary on anything from policy to personal appearance. 'Was Huma Abedin wearing beer goggles the night she met Anthony Weiner,' he tweeted, referring to the scandal-hit former New York mayoral candidate and his wife, a former aide of Hillary Clinton. He tweeted that Mrs Clinton 'had few policy goals and no wins' in the Middle East. He said Chelsea Clinton was 'assuming all of her parents' vices,' and targeted figures such as Republican commentator Liz Cheney and Mitt Romney's wife Ann for their looks and weight. Many in the foreign policy community reacted with shock to the revelation that Joseph was the mystery tweeter because Joseph was well known among policy wonks and his wife, Carolyn Leddy, is a well-respected professional staffer on the Republican side of the Senate Foreign Relations Committee. 'What started out as an intended parody account of DC culture developed over time into a series of inappropriate and mean-spirited comments,' said Joseph in an apology. 'I bear complete responsibility for this affair and I sincerely apologize to everyone I insulted.'"

An anonymous reader writes with a story excerpt that may inspire envy in some readers: "Most beer guts are the result of consuming fermented brew, but a new case study describes a rare syndrome that had one man's gut fermenting brew, not consuming it. It's called gut fermentation syndrome or auto-brewery syndrome, and it's 'a relatively unknown phenomenon in Western medicine' according to a study published in July's International Journal of Clinical Medicine. 'Only a few cases have been reported in the last three decades' according to Dr. Barbara Cordell, the dean of nursing at Panola College in Carthage, Texas, and Dr. Justin McCarthy, a Lubbock gastroenterologist, the study's authors."

SkyOS Now Free (As In Beer) 88

Posted by Unknown Lamer
from the free-as-in-dead dept.
Beardydog writes "SkyOS, the commercial, alternative OS created almost entirely by Robert Szeleney, became free (as in beer) sometime last month. Alternative OS enthusiasts can be forgiven for missing it, as the website has been largely derelict, and the forums overrun with spam, since the project was halted in 2009. It's not clear from the announcement whether the ISO available is the traditional build, or the version rebuilt around Linux. The post announcing the free version provides a license name ('public') and registration code that must be entered during setup. While it isn't quite the open-sourcing that most followers hoped for, it's heartening to know SkyOS won't be completely lost in the mists of time."

Red Hat CEO: Bring On the Clones 182

from the canonical-source-of-red-hat dept.
An anonymous reader writes "Best Buy and Barnes and Noble have a problem with showrooming — shoppers checking out the merchandise in their stores and then proceeding to order the goods at a discounted prices online. And Red Hat might have a similar problem with people (not just college kids and software professionals boning up on their skills at home, either) using the free-as-in-beer CentOS rather than licensing Red Hat Enterprise Linux and paying support fees. But according to CEO Jim Whitehurst, Red Hat's competitive position may actually be helped by CentOS in the same way that counterfeit Windows products sold on the streets in the Far East may have helped Microsoft — by cementing their position as the technology standard, in a marketplace that also includes entrants from SuSE, Debian, Oracle, and Ubuntu, just among Linux-based entrants. Who does Whitehurst consider to be Red Hat's most direct threat? VMWare."

Do-It-Yourself Brain Stimulation Has Scientists Worried 311

from the a-little-zap-will-do-you dept.
Freshly Exhumed writes "Dave Siever always fancied himself as something of a musician, but also realized he did not necessarily sing or play in perfect key. Then he strapped on the electrodes of a device made by his Edmonton company, and zapped his brain's auditory cortex with a mild dose of electricity. The result, he claims, was a dramatic improvement in his ability to hear pitch, including the sour notes he produced himself. 'Now I tune everything and I practise my singing over and over and over again, because I'm more sensitive to it.' Mr. Siever was not under the supervision of a doctor or psychologist, and nor is he one himself. He is part of an extraordinary trend that has amateur enthusiasts excited, and some scientists deeply nervous: do-it-yourself brain stimulation." With studies suggesting that small doses of electricity can: increase your memory, help you learn new tasks, make you better at math, turn you into a sniper in minutes, and most importantly make the ugly seem attractive, we can expect a lot of brain zapping in the next few years.
