How To Create A Designer Baby



From Popular Mechanics:

Increasingly sophisticated genetic tests make it possible for parents to choose their baby’s traits. Here are three ways babies are born to specifications.

For just an extra few thousand dollars, women undergoing in vitro fertilization (IVF) could one day choose to have a baby boy with perfect vision, an aptitude for sports and a virtual lock on avoiding colon cancer. Fertility clinics in the U.S. currently offer not only to screen for diseases, but also to choose gender. They are not yet offering any further customization, but that could change as genetic mapping gets faster and easier.

The Lithium Rush


From Technology Review:

In the Bolivian Andes lies a vast salt flat that may shape the future of transportation.

Nearly four kilometers above sea level in the Bolivian Andes lies the Salar de Uyuni, the world's largest salt flat. But there is more to this ­surreal, moonlike landscape than meets the eye. Flowing in salt-water ­channels beneath the surface is the world's largest supply of lithium--and, possibly, the future of transportation. Lithium is the key ingredient in the lithium-ion batteries that will power the electric vehicles that will soon be rolling off production lines worldwide. Demand for the metal is expected to double in the next 10 years, and Bolivia, with an untapped resource estimated at nine million tons by the U.S. Geological Survey, is being called a potential "Saudi Arabia of lithium."

Top Scientists Share Their Future Predictions

Neo (Keanu Reeves) in a still from The Matrix

From Times Online:

From virtual brains and Matrix-like thought connections to disease-making bacteria, what the next decade could bring.

Nothing much is going to happen in the next 10 years. Of course, that’s not counting the diesel-excreting bacteria, the sequencing of your entire genome for $1,000, massive banks of frozen human eggs, space tourism, the identification of dark matter, widespread sterilisation of young adults, telepathy, supercomputer models of our brains, the discovery of life’s origins, maybe the disappearance of Bangladesh and certainly the loss of 247m acres of tropical forest.

As I said, just another decade really.

Why Some Continue To Eat When Full: Researchers Find Clues


From Science Daily:

Science Daily (Dec. 28, 2009) — The premise that hunger makes food look more appealing is a widely held belief -- just ask those who cruise grocery store aisles on an empty stomach, only to go home with a full basket and an empty wallet.

Prior research studies have suggested that the so-called hunger hormone ghrelin, which the body produces when it's hungry, might act on the brain to trigger this behavior. New research in mice by UT Southwestern Medical Center scientists suggest that ghrelin might also work in the brain to make some people keep eating "pleasurable" foods when they're already full.

From Live Science:

Like years past, this one has been a whopper for high-profile philanderers. Psychologists aren't surprised, as guys are wired to want sex, a lot, and are more likely than gals to cheat. The behavior may be particularly likely for men with power, researchers say, though they point out that despite the genetic propensity to sleep around, cheating remains a choice, not a DNA-bound destiny.

The list of powerful individuals whose marital transgressions came out this year includes Tiger Woods, David Letterman, former senator John Edwards and South Carolina Gov. Mark Sanford.

You've heard of planes that vanished into thin air? Here's a truer, scarier story: On Oct. 21, 2009, two pilots flying from San Diego to Minneapolis vanished into cyberspace.

Their plane was fine. Ground controllers tracked it the whole time. The passengers and flight attendants in the main cabin noticed nothing unusual. And the pilots' bodies stayed planted in their seats as though they were flying the aircraft. But they weren't flying it. Their minds had been sucked into a pair of laptops.

Sea urchins may use the whole surface of their bodies as compound eyes, scientists now suggest.

Although sea urchins don't have any problems avoiding predators or finding comfortable dark corners to hide in, they don't have eyes. The question then is how they see.

Genetic analysis of sea urchins has revealed they have light-sensitive molecules, mostly in their tube feet and in tiny stalked appendages found in among their spines. As such, "it looks like the entire surface of their bodies are acting as one big eye," said researcher Sönke Johnsen, a marine biologist at Duke University.

Pulling The 'Mating Plug' May Reduce Mosquito Population And Malaria Rates

A malaria-carrying Anopheles gambiae mosquito. About 40% of the world's population is at risk of malaria, a potentially deadly disease. (CDC / December 26, 2009)

From The L.A. Times:


Scientists find that reproduction fails when they interfere with the enzyme that causes the plug to form. The team hopes the finding can be developed for use in the field.

Interfering in mosquitoes' sex lives could help halt the spread of malaria, British scientists said this week.

A study on the species of mosquito mainly responsible for malaria transmission in Africa, Anopheles gambiae, showed that because these mosquitoes mate only once in their lives, meddling with that process could dramatically cut their numbers.

Airport screening procedures failed for many reasons to catch the Nigerian man who aimed to blow up flight 253 as it approached Detroit. Scanners that might have spotted the explosives are not fully deployed, and even at airports where they exist, the scanners aren't used on all passengers.

Bottom line: No system will likely prove foolproof, experts say.

Investigators say 23-year-old Nigerian Umar Farouk Abdul Mutallab hid an explosive device and the chemical explosive PETN on his body while traveling from Amsterdam to Detroit aboard the Delta flight on Christmas day.

Amazon: Kindle Is Most Gifted Item Ever

From PC World:

Amazon's Kindle e-book reader hit a watershed moment on Christmas Day, when, for the first time ever, customers purchased more Kindle books than physical books. The company also claims the Kindle is the most gifted item in Amazon's history. These two facts were part of the online retailer's recently announced holiday sales activity.

But in typical Amazon style, the company did not provide any sales figures to back up its claims. Although Amazon did say that if you placed side by side all the Blu-ray disc players the company sold this season, the line would stretch for more than 27 miles. A mile has 63,360 inches, so I'll leave you to make your best guess.

The Department of Mad Scientists -- A Book Review

From New York Times:

Two years ago, in his book “Rocketeers,” Michael Belfiore celebrated the pioneers of the budding private space industry. Now he has returned to explore a frontier closer to home. The heroes of his new book, “The Department of Mad Scientists,” work for the Defense Advanced Research Projects Agency, better known as Darpa, a secretive arm of the United States government. And the revolution they’re leading is a merger of humans with machines.

The revolution is happening before our eyes, but we don’t recognize it, because it’s incremental. It starts with driving. Cruise control transfers regulation of your car’s speed to a computer. In some models, you can upgrade to adaptive cruise control, which monitors the surrounding traffic by radar and adjusts your speed accordingly. If you drift out of your lane, an option called lane keeping assistance gently steers you back. For extra safety, you can get extended brake assistance, which monitors traffic ahead of you, alerts you to collision threats and applies as much braking pressure as necessary.
