Craig Venter Comes One Step Closer To World Domination

US genomics pioneer Craig Venter, best known for his success with the Human Genome_Project, informed the world today of his groups success in converting one type of bacteria into another:

Venter's team, led by John Glass of the J. Craig Venter Institute in Rockville, Maryland, US, managed to transfer the genome of Mycoplasma mycoides to a related parasite called M. capricolum. Both species infect goats, sheep and cows.

...

The researchers took a strain of M. mycoides that is resistant to the antibiotic tetracycline, broke open the cells and carefully "digested" the proteins, leaving just the intact circular chromosomes, the DNA.

These chromosomes were then incubated with M. capricolum cells in a polymer medium that encourages cell membranes to fuse. The researchers speculate that some M. capricolum cells fused together, encapsulating an M. mycoides chromosome as they did so.

Finally, the researchers treated their cultures with tetracycline, so that only M. capricolum cells containing the M. mycoides genome would survive.

Venter's group is hailing the operation as a crucial step towards their goal of creating a synthetic life form, with the creation of a synthetic life form being a crucial step to creating an army of moldiers, and moldiers being a crucial step towards world domination. Clearly, because nobody tinkering around in the field of biology has ever done anything positive for humanity, this week's progress marks the beginning for the end of mankind as well as the beginning of what will come to be known as "Venter's Reign of Terror."

Pauly Shore: There Is Hope For You Yet


Biosphere 2 has been saved! I always thought that biospheres were cool. Especially because they were the precursors to living on the moon or on Mars. Unfortunately, everyone just came out of the biodomes just hating each other. But, BioSphere 2 is going to be saved...at least for another few years.
It belongs to the University of Arizona and they are going to try to keep it open as and environmental laboratory and not, you know, a bunch of McMansions.


The university has now leased the property for scientific research with the aid of gifts and grants, and funds permitting, will try to extend the lease for 10 years.

Nestled in the Santa Catalina Mountains north of Tucson, Arizona, the great glass greenhouse was built 20 years ago by Space Biosphere Ventures as an artificial closed ecological system.

When, in 1991, eight people were sealed inside, it was hailed as a dry run for building a colony on Mars. But two years later, when the same eight emerged emaciated from poor diets and embittered by infighting, critics were quick to call the project a failure.


I tell you what though. BioDome the movie was NOT a failure, I loved that movie.

Yay, Plastic Bags Finally Good for Something


A new microwave contraption has been developed that turns classic garden variety plastic bags into oil and gas. (Back from whence you came, plastic bag!) This is good news on two fronts. First, oil is yummy and we are addicted to it. Secondly, plastic bags are clogging our waterways and killing our birds and fish because they apparently try to eat the damn things. See National Geographic article here.


All that is needed, claims Global Resource Corporation (GRC), is a finely tuned microwave and – hey presto! – a mix of materials that were made from oil can be reduced back to oil and combustible gas (and a few leftovers).

Key to GRC’s process is a machine that uses 1200 different frequencies within the microwave range, which act on specific hydrocarbon materials. As the material is zapped at the appropriate wavelength, part of the hydrocarbons that make up the plastic and rubber in the material are broken down into diesel oil and combustible gas.

So, watch out grocery stores. Soon oil barons will be stealing your plastic bags to turn into oil to sell at outrageous prices.

I Call Bologna Sandwich on You Researchers


A new study has been released that Europe has just had the warmest winter and fall in 700 years. Wait one cotton-picking minute. 700 years? Was the thermometer around in 1300? No, probably not, so let's see what they do.


European climate measurements and temperature records stretch back several hundred years – UK records are the longest available, going back to 1659. Estimating historical temperatures beyond then involves scrutinizing contemporary documents and diaries.

"People in churches, or doctors, wrote diaries, and usually they also included information about weather and climate. Climate historians can use and interpret this information and translate it into a temperature value," explains Luterbacher, who worked with climate historians to compare past and recent temperatures

So, your "data" that this is the hottest winter EVAR is based on the fact that you read in some girls diary from 1289 that it was "omg, hawt out" (That's not a direct quote. It probably was more like, "me lord thinks it is too warm out to take a gander at the rose garden methinks.)
I'm sure you love making headlines that pop, but this is just merely hearsay. This is not science. I'm sorry, but let's say this was the hottest winter in 300 years. That works and that it actually true.

Single Ladies, Make Noise!


If you got a hundred dollar bill, put your hands up!
Anyhow, that is enough Fatman Scoop for now. But, in the latest National Geographic, they have published a map that details where the greater populations of single men live and single women live. Blue is overwhelming populations of single men, red is single women. This is honestly shocking to me, Silicon Valley makes sense, but maybe my West Coast corespondent can log in and let me know if there is actually zillions more single men in LA than women. From living on the East Coast for the past few years, I would not have guessed that the entire coast is figuratively throbbing with single women. I guess I must have hung out at the wrong places.
In either case...West of the Mississippi River there is a whole lotta dudes.

Scientists Say: Nuclear War Still Bad.


Scientists at Rutgers University have completed a study on nuclear wars and nuclear winters by "simulating" bomb explosions over major cites. They "simulated" the explosion of 100 nuclear bombs. And hopefully not to their surprise, the nuclear winter afterwards would really suck. Unless you died in the bomb, then the weather would be ok.


They found that the blasts would loft up to 5 million tonnes of black carbon soot into the atmosphere, lowering global temperatures by 1.4 °C. Growing seasons in the middle latitudes would be shortened and in some cases fail entirely. "By explaining the consequences to the world, we hope nothing like this will ever happen," says Robock.

Yes, thank you for discovering that a nuclear war would really suck for everyone.
'Nuclear winter' is still a threat to be avoided

Never Under Estimate the Power of Drunk Teenagers


Some industrious teenagers in the amazing nation city of Amsterdam have found a way to make powdered alcoholic drinks. Just add water and you get a lemony-lime flavored drink with 3% alcohol content. And potentially, the kids are saying you could sell this to minors and the laws (in Amsterdam) prevent the selling of liquid alcoholic drinks to minors.


"We are aiming for the youth market. They are really more into it because you can compare it with Bacardi-mixed drinks," 20-year-old Harm van Elderen told Reuters.

Van Elderen and four classmates at Helicon Vocational Institute, about an hour's drive from Amsterdam, came up with the idea as part of their final-year project.

"Because the alcohol is not in liquid form, we can sell it to people below 16," said project member Martyn van Nierop.

And get this, the name of the product is: Booz2Go. Of course it is. Way to go kids. Way to go.

Red is the New Terrible


Two studies have come out recently that are piling on our red-headed cousins. First, apparently redheadism (I'm coining that word now!) is just as bad as racism. (As all black people scoff loudly.) Apparently, copper-tops face jokes at school and even in the workplace.


"In other countries redheads will get teased at school but it stops when they become adults. If you are a woman you are fiery and alluring, beautiful."
In adult life, women get stereotyped and red-haired men take much of the worst abuse. Treatment of red-haired children in school ranges from mild taunts to grim persecution.
Michele Eliot, the American director of British children's charity Kidscape, regularly has significant numbers of red-haired children in courses on coping with bullying.

The article seems to suggest that this phenomenon is limited to the UK, but also hints that these Duracells face persecution everywhere.
---
But, it looks like it is going from bad to worse for our fire-headed friends as another study has come to the conclusion that redheads do not deal with pain well and are more likely to feel pain. I'll let the doc explain, since this is in fact a science blog.

Dr Liem said the findings could be explained by genetics, and in particular variations in the melanocortin 1 receptor which is linked to red hair.

He said the discovery could help scientists to find out more about how the body manages pain.

"Since red hair can be traced to particular mutations in the melanocortin 1 receptor, we now have the opportunity to evaluate central nervous system pathways that may influence or mediate anaesthetic requirement," Dr Liem said.

"Investigating the role of melanocortin system in the central nervous system is thus likely to help us understand fundamental questions such as which systems in the brain produce unconsciousness and which modulate pain perception."

If that was a little too much science jargon for you, I'll let the doc break it down, layman style.

In a nutshell, redheads are likely to experience more pain from a given stimulus and therefore require more anaesthesia to alleviate that pain.

No word on how the redheads do outside the nutshell. (Thank you very much, I'll be here all week.)
In conclusion, redheads, it sucks to be you. You feel more pain when bullys beat you up just for being born redhead. At least you (used to) have Lindsay Lohan.
