From Minnie To Mickey (And All They Did Was Turn Off A Gene)

The cells of the female ovary were transformed into cells normally found in male testes by turning off a gene during the development of the mouse embryo. Alamy

From The Independent:

Simple technique changes sex of a mouse – and reveals the gender war that rages in all of us.

The battle of the sexes is a never-ending war waged within ourselves as male and female elements of our own bodies continually fight each other for supremacy. This is the astonishing implication of a pioneering study showing that it is possible to flick a genetic switch that turns female ovary cells into male testicular tissue.

Super Soldier Updates

From the Next Big Future:

DARPA has a program that is spending about $3 billion to create super soldiers. Here is an update of technology that is ready or is becoming deployable or usable for the purpose of creating super soldiers. Much of it is not from DARPA.

Exoskeletons
1. The Human Universal Load Carrier (HULC™) exoskeleton runs on Li-ion batteries, driving lightweight hydraulic legs with titanium structure. A wearer can hang a 200lb backpack from the back frame and heavy chest armour and kit from shoulder extensions.

According to Lockheed reps the HULC isn't ready for prime time yet, being still "in ruggedisation". However the company would envisage giving it to actual soldiers so as to get their input from the summer of 2010.

What NASA's WISE Space Mapper Will Look For In The Sky

The 40 cm diameter WISE telescope is an all aluminum optical system that will produce images of the sky with 2.75 arcsec resolution in four infrared spectral bands. Here the lead optical test engineer attaches the back-end imager optics to the afocal. This entire telescope will be mounted inside the WISE cryostat and cooled to about 17K. The WISE telescope was developed by L3 Communications-SSG.

From Popular Mechanics:

Early on Friday, NASA will launch its newest satellite, the Wide-Field Infrared Survey Explorer (WISE). Its mission: To catalogue the murky parts of our universe in never-before-seen detail. As the craft orbits Earth, it will capture images of the sky with an infrared digital camera that snaps pictures every 11 seconds. So what's out there that WISE's team of astronomers are so eager to see? Here's a list.

Darpa's Cyborg Insect Spies, Now Nuclear-Powered

From Popular Science:

When you write for Popular Science, it's easy to become desensitized to wild and crazy future tech. To wit: When I first heard that Darpa wanted to develop cyborg insects to carry surveillance equipment, I thought "ok, cyborg insect spies are pretty cool, but not blowing me away."

Then today, Cornell researchers working on the program unveiled a prototype transmitter for the cyborg bugs that runs on radioactive isotopes. Nuclear powered cyborg insect spies? Ok, now you have my attention.

First-Born Children Are More Successful But Less Trusting

From The Telegraph:

First-born children are more likely to achieve greatness but at the cost of being less co-operative and less trusting than their younger siblings.

Research suggests that first borns are generally smarter and more likely to become leaders compared to their younger brothers and sisters.

However this appears to make them more cynical and less likely to trust others or co-operate with them, according to research.

Deepwater Wind To Build First U.S. Ocean Wind Farm

From CNET News/Reuters:

The tiniest state in the nation may build the first U.S. offshore wind farm, after privately held Deepwater Wind on Thursday landed a deal to sell power from the first phase of a Rhode Island project that eventually could supply 15 percent of the state's electricity.

Under a 20-year power purchase agreement, developer Deepwater Wind will sell electricity from up to 8 turbines producing 28 megawatts to National Grid.

Earlier this year Rhode Island set a target to obtain 20 percent of its electricity from renewable resources by 2015.

The ocean crossing is thought to be a first for the robotic device that looks like a small torpedo with wings, and was powered only by batteries that allowed it to change buoyancy so it could catch ocean currents.

A similar effort in 2008 failed and the device was never recovered.

Swine Flu Has Hit About 1 In 6 Americans, CDC Says

From The L.A. Times:

Although nearly 10,000 have died from H1N1, that is a lower mortality rate than in regular flu seasons, the CDC chief says. What's different is that more children and adults under 50 have died, he say.

About 50 million Americans had contracted pandemic H1N1 influenza through Nov. 14, according to the newest estimates from the Centers for Disease Control and Prevention released Thursday -- meaning that about 15% of the entire country has been infected, about one in every six people.

"That still leaves most people not having been infected and still susceptible," CDC Director Dr. Thomas R. Frieden said at a news conference. The agency also reported that more than 200,000 people had been hospitalized and nearly 10,000 had died.

Making Diesel From CO2 And Sunlight

Metal eater: Metallosphaera sedula can draw energy from a copper-iron sulfide called chalcopyrite, the black substance shown here. As it feeds, it produces copper ions (green), iron oxide (orange), and sulfur (yellow). The organism uses the energy from the sulfides to produce acetyl-CoA, a fundamental building block in cells. Researchers have been able to engineer organisms to convert acetyl-CoA into butanol and other liquid fuels. Credit: Robert Kelly, North Carolina State

A new "electrofuels" program announced this week by the Advanced Research Projects Agency-Energy (Arpa-e) will fund research into novel ways to make renewable fuels. The approaches could prove more efficient than using photosynthetic organisms--such as plants and algae--to make biofuels. And instead of making ethanol, they will make fuels such as diesel, which could be easily distributed and sold with existing infrastructure.

The "real-time Web" is a hot concept these days. Both Google and Microsoft are racing to add more real-time information to their search results, and a slew of startups are developing technology to collect and deliver the freshest information from around the Web.

But there's more to the real-time Web than just microblogging posts, social network updates, and up-to-the-minute news stories. Huge volumes of data are generated, behind the scenes, every time a person watches a video, clicks on an ad, or performs just about any other action online. And if this user-generated data can be processed rapidly, it could provide new ways to tailor the content on a website, in close to real time.

‘Testosterone’s Aggressive Impact Is A Myth. It Makes You Friendlier’

Far from always increasing aggression and greed, the male hormone can actually encourage decency and fair play, scientists have discovered.

The common belief that it makes people quarrelsome, however, can cause it to have that effect. When people think they have been given supplements of the hormone they tend to act more aggressively, even though it does nothing biological to promote such behaviour.
