Get Ready For UHD-TV – “UHD will come in two resolution levels: 7680 x 4320 pixels (8K) and 3840 x 2160 pixels (4K) and provide four to 16 times the resolution of Blu-ray or 1080p high-def. And “22.2 multichannel three-dimensional sound.”"

Intel’s CULV Laptops: Thin, Light & Cheap – “CULV, which stands for consumer ultra low voltage, isn’t a new technology for Intel. In fact, these processors commanded high premiums two years ago and were found in ultraportables that range upwards of $2,000. With CULV, Intel merely re-branded these processors, created new ones in the process, and began selling them in laptops that are less than an inch thick, average 13-inch widescreens, and don’t necessarily include optical drives. Most compelling of all, CULV laptops cost between $600 and $900 and delivered great battery life…”

How to tell if your robot really loves you – “Anyone watching the TED video below, will see that David Hanson’s robot heads look and act human. They recognize and respond to emotion, and they make amazingly realistic expressions of their own. The technology to give robots human-like capabilities for body movement is also coming along quite impressively…”

Mapping the Mammal Takeover – “If you were to construct a family tree vast enough to link all mammals—from the duck-billed platypus to Homo sapiens—put it on a time line, and shape it into a circle, this is what it would look like. A team of researchers compiled data from 4,500 existing mammal species—99 percent of known mammals alive today—and charted their evolution over 170 million years. Time begins at the center of the circle and moves out toward the present day (indicated along the circumference). This chart shows that the extinction of dinosaurs wasn’t key for the diversity of present-day mammalian evolution, that rats aren’t just pests (they’re survivors), and that humans aren’t all that special…”

Google Dashboard Opens User Data

November 5th, 2009 by Chris Pollette

Privacy in the digital age is a matter of some concern. One of the things about electronic files is that they’re easy to duplicate and transfer. And lots of companies are storing lots of personal information. After all, they’re using it to market goods and services to you. It’s big business.

That’s why Google’s recent move toward transparency is a big deal. Miguel Helft wrote an article in The New York Times about it. The announcement came at a privacy conference in Spain earlier today. Google will be offering a new service (how many times have I written that in blog posts this year?) called Google Dashboard. All of the information you’ve supplied in your various Google service accounts will be listed there, including Gmail, Picasa, Checkout, Reader and others.

Actually, as Helft pointed out, Google Dashboard isn’t all that revolutionary, because that information was available to the user through the account settings pages on the individual services.

Invention – inflatable seat belts

The first innovation in seat belt design in many years is on its way:

Ford says inflatable seat belt improves safety, comfort, too

The belts expand like an air bag in the event of a crash and distribute the force of the impact across a wider area of the passenger’s chest.

In the video you can still see one of the most pressing problems with seat belts – head motion. The following video explains that 25% of the money paid by insurance companies for injuries has to do with whiplash injuries:

One way to fix that would be to have all of us wear helmets with HANS devices installed, as shown here:

Maybe we see that next year.

A new way to build an eletric car

November 5th, 2009 by Marshall Brain
Add Comment

Electric cars are taking off, as seen with this collection of electric concept cars at the Tokyo Auto Show:

The cars come in all shapes and sizes, but here is one that is following what appears to be a unique path:

F1 designer unveils electric car

This is the T27. It is intended as a “city car” with a top speed of 60 MPH and a range of 100 miles. It has a number of innovative features designed to cut costs and weight, but two of the most important are these:

1) It contains few (no?) stamped metal parts. If you go to a traditional auto factory, the stamping presses are huge and incredibly expensive, as are the stamping dies. By doing away with them, the manufacturing process is simplified. In the following video, you get a sense of the size of a stamping press:

Instead of stamping the parts, “All the parts are designed by computer and welded together rather than being stamped out of metal sheets.”

2) The car is very light without compromising safety:

Its predecessor, the T.25, weighs 600kg – half the weight of an average small family car.

“Cars don’t tend to be heavy because of safety; they tend to be heavy because of luxury,” added Mr Bott.

“The tubular frame of the T.27 is designed to absorb energy. It will pass all the relevant safety tests.”

If this works out, it could mean that perhaps many smaller car manufqacturers could sprout up to build electric cars.

The Mother of all Footraces on “The Mother Road”

I don’t know about driving Route 66. But I think running Route 66 would be pretty awesome.

Back in 1928, when Route 66 was just a baby, civic leaders were looking for ways to publicize the road’s existence. Someone made a joke at a Route 66 dinner about hosting a footrace, and everyone laughed. But some folks didn’t think it was such a bad idea.

How to Eat Like a Brit Tonight

November 5th, 2009 by Molly Edmonds

“Remember, remember the fifth of November.” So goes the old rhyme about Guy Fawkes and his plot to blow up the British Houses of Parliament. In 1605, Fawkes and his cronies were unhappy with the king’s discrimination against Catholics, so they smuggled gunpowder into the basement of the House of Lords. Much mayhem would have ensued, but the conspirators were caught and killed. Now, centuries later, the British still gather on this date for Bonfire Nights, where they burn effigies of Guy Fawkes and watch fireworks.

Being born and bred in the United States, this celebration seems a little odd to me, but I do love a good excuse to watch fireworks, particularly if there’s tasty food involved. That’s why I decided to do a little digging into the party fare of Guy Fawkes Night.

Good grief! Am I alone in thinking that the Ferrari Enzo DOES NOT belong on BusinessWeek’s list of the (supposedly) 50 ugliest cars of the past 50 years? Oh, but the madness doesn’t stop there. Several other questionable picks made the list, too.

What is the fastest and easiest way to speed up my metabolism?

November 5th, 2009 by Marshall Brain
Add Comment

You Asked:

What is the fastest and easiest way to speed up my metabolism? — Joanne, Los Angeles, Calif.

Marshall Brain Answers:

The dictionary defines metabolism as: “all the physical and chemical processes in the body that create and use energy.” The Krebs cycle would be an example of a metabolic process happening inside your cells.

When people talk about speeding up their metabolism, however, what they are usually trying to do is burn more calories throughout the day to lose weight. Everyone has a basal metabolic rate – the rate at which your body burns energy when you are idling. Since most modern humans spend most of their time idling (sitting in chairs, lying on couches, sleeping in beds, driving in cars, etc.), any increase to the basal rate would help to lose weight over time (provided you don’t increase your calorie intake at the same time – see How Dieting Works for details).

The easiest way to speed up your metabolism is to idle less. When you exercise, your metabolism automatically increases to produce the energy needed to move. There’s a side benefit as well – by exercising you increase your muscle mass, and muscle mass burns more calories when you are idling. If you were to lift weights regulary and really bulk up, the number of calories you burn when idling would go up significantly. This paper shows the potential:

Effect of an 18-wk weight-training program on energy expenditure and physical activity

In conclusion, although of modest energy cost, weight-training induces a significant increase in ADMR (average daily metabolic rate).

The average daily increase was 9.5%.

Note also that every little bit helps when it comes to exercise, so if you were to take four 10-minute walks during work hours, that would be better than sitting idle all day. Running up and down the fire escape stairs instead of walking might even be better.

Many web sites, like this one, also talk about the importance of breakfast when it comes to metabolism:

Believe it or not, it may be the most important meal of the day as far as metabolism (and weight loss) is concerned. Breakfast eaters lose more weight than breakfast skippers do, according to studies. “Your metabolism slows while you sleep, and it doesn’t rev back up until you eat again,” explains Barbara Rolls, Ph.D., professor of nutrition at Penn State University and an author of The Volumetrics Weight-Control Plan. So if you bypass breakfast, your body won’t burn as many calories until lunchtime as it could. That’s why it’s smart to start the day with a solid 300- to 400-calorie meal; it jump-starts your metabolism.

Nibbling (eating many times a day in much smaller meals, rather than eating a few big heavy meals) is also recommended as a way to keep metabolism uniform throughout the day.

You did ask, “What is the fastest and easiest way to speed up my metabolism?” In the interest of completeness (rather than safety), we should probably mention nicotine. According to this page:

Cigarette smoking increases a person’s metabolic rate in part by forcing the heart to beat faster. When a cigarette is inhaled, the smoker’s heart may beat 10 to 20 times more per minute for a period of time. This causes extra stress on the heart and plays a role in heart disease, the most common cause of smoking-related death. And think about this: A smoking habit of 20 cigarettes a day puts approximately the same amount of stress on the heart as 90 pounds of extra weight would. When we stop smoking, heart rate slows down somewhat, causing metabolism to dip a bit as well.

See also: How Nicotine Works and How to quit smoking (which mentions nicrotine gum as an alternative nicotine source if you are trying to quit).

Games – Two space battle games

November 5th, 2009 by Marshall Brain

The first is free, inspired by the 2D shooters of the Galactica era but with customization:

Red Fluxion

The guy who wrote the game is taking feedback in this thread

The second has a free demo:

Gatuitous Space Battles

It’s a strategy / management / simulation game that does away with all the base building and delays and gets straight to the meat and potatoes of science-fiction games : The big space battles fought by huge spaceships with tons of laser beams and things going ‘zap!’, ‘ka-boom!’ and ‘ka-pow!’. In GSB you put your ships together from modular components, arrange them into fleets, give your ships orders of engagement and then hope they emerge victorious from battle (or at least blow to bits in aesthetically pleasing ways).

This is what the game looks like when you play it:
