When Will We Be Able To Build Brains Like Ours?

Image: Henrik5000

From Scientific American:

Sooner than you think -- and the race has lately caused a 'catfight'.

When physicists puzzle out the workings of some new part of nature, that knowledge can be used to build devices that do amazing things -- airplanes that fly, radios that reach millions of listeners. When we come to understand how brains function, we should become able to build amazing devices with cognitive abilities -- such as cognitive cars that are better at driving than we are because they communicate with other cars and share knowledge on road conditions. In 2008, the National Academy of Engineering chose as one of its grand challenges to reverse-engineer the human brain. When will this happen? Some are predicting that the first wave of results will arrive within the decade, propelled by rapid advances in both brain science and computer science. This sounds astonishing, but it’s becoming increasingly plausible. So plausible, in fact, that the great race to reverse-engineer the brain is already triggering a dispute over historic “firsts.”

In Search Of The Perfect Wine

Can genetic engineering make wine even better?

From Cosmos:

Using genetic engineering and the latest science, researchers are learning how to manipulate wine's previously elusive qualities. It may be about 8,000 years old, but never has wine tasted this good.

Holding a glass of wine by its stem, careful not to warm the liquid with body heat, you raise it to the light above your head. The bright, clear liquid is the shade of pale straw, informing you of its youth and pure character.

The Future For Night Vision Goggles

Night Vision Once the domain of military and police, a cheap thin-film approach to night vision could give cell phones, eyeglasses, and car windshields the ability to see in the dark.

A Cheap, Thin Film Gives Portable Night Vision to Cell Phones and Eyeglasses -- Popular Science

What we regularly refer to as “night vision goggles” are actually less like goggles and more like heavy, bulky (and outrageously expensive) pieces of machinery. But DARPA funded research at the U. of Florida has adapted technology regularly found in flat-screen OLED televisions to create a thin film that turns any infrared signal into visible light, which could integrate cheap night vision tech into car windshields, cell phone cameras and even regular eyeglasses.

From Astrobiology Magazine:

When Pluto was discovered in 1930, it was considered to be the ninth planet of our solar system. Since that time, astronomers have discovered similar icy objects in that far-distant orbital region of the Sun known as the Kuiper belt. Many astronomers questioned whether Pluto should be grouped with worlds like Earth and Jupiter, and in 2006 this debate led the International Astronomical Union (IAU), the recognized authority in naming heavenly objects, to formally re-classify Pluto as a dwarf planet.

What Climate Change Means For Wine Industry

From Wired Science:

John Williams has been making wine in California’s Napa Valley for nearly 30 years, and he farms so ecologically that his peers call him Mr. Green. But if you ask him how climate change will affect Napa’s world famous wines, he gets irritated, almost insulted.

“You know, I’ve been getting that question a lot recently, and I feel we need to keep this issue in perspective,” he told me. “When I hear about global warming in the news, I hear that it’s going to melt the Arctic, inundate coastal cities, displace millions and millions of people, spread tropical diseases and bring lots of other horrible effects. Then I get calls from wine writers and all they want to know is, ‘How is the character of cabernet sauvignon going to change under global warming?’ I worry about global warming, but I worry about it at the humanity scale, not the vineyard scale.”

From Science Daily:

ScienceDaily (Apr. 26, 2010) — Laughter is a highly complex process. Joyous or mirthful laughter is considered a positive stress (eustress) that involves complicated brain activities leading to a positive effect on health. Norman Cousins first suggested the idea that humor and the associated laughter can benefit a person's health in the 1970s. His ground-breaking work, as a layperson diagnosed with an autoimmune disease, documented his use of laughter in treating himself -- with medical approval and oversight -- into remission. He published his personal research results in the New England Journal of Medicine and is considered one of the original architects of mind-body medicine.

The oil slick that is expanding from the site of an oil rig collapse last week has been spotted from space by a NASA satellite.

An estimated 42,000 gallons of oil per day are leaking from an oil well in the Gulf of Mexico after an oil rig caught fire and then sank into the ocean waters last week.

The only oil evident in the water at first was that which had been on the rig itself at the time it exploded on April 20. Over the weekend, officials working on the oil spill discovered that water was also leaking from the pipe that led up to the rig from the well some 5,000 feet (1,524 meters) below on the seafloor.

Levels of 'viable' sperm in human males are falling – and scientists believe they now understand the cause. Infertility can begin in the womb, says Steve Connor.

If scientists from Mars were to study the human male's reproductive system they would probably conclude that he is destined for rapid extinction. Compared to other mammals, humans produce relatively low numbers of viable sperm – sperm capable of making that long competitive swim to penetrate an unfertilised egg.

A Counter Argument That Our Obesity Epidemic Is Not A Threat To National Security

From Slate:

The obesity epidemic has nothing to do with national security.

"My name's Dewey Oxberger; my friends call me 'Ox'. You might've noticed I've got a slight weight problem," said John Candy to his fellow Army recruits in the 1981 film Stripes. "So I figured while I'm here, I'll lose a few pounds. I'm gonna walk out of here a lean, mean fightin' machine!"

In real life, the 6-foot-2, 300-pound Ox wouldn't have made it through the barracks door. The movie's release coincided with a new weight-control program in the U.S. military. Recruits were already screened for height and weight; now they'd be checked for body fat percentage, too. It's been 30 years since Stripes came out, and the rate of obesity among adults has doubled. A report out this week estimates that 27 percent of all Americans of recruitment age—that's 9 million young adults—are too fat to fight for their country. At a press conference Tuesday, Sen. Richard Lugar, Agriculture Secretary Tom Vilsack, and a group of retired generals and admirals warned that our poor diets and lack of exercise have now become a danger to homeland security.

Energy Research Spending Seen As Chump Change

From Future Pundit:

Microsoft co-founder Bill Gates and former Dupont CEO Chad Holliday say we spend too little on energy R&D and energy is a big problem.

But our country is neglecting a field central to our national prospect and security: energy. Although the information technology and pharmaceutical industries spend 5 to 15 percent of their revenue on research and development each year, U.S. companies' spending on energy R&D has averaged only about one-quarter of 1 percent of revenue over the past 15 years.

And despite talk about the need for "21st-century" energy sources, federal spending on clean energy research -- less than $3 billion -- is also relatively small. Compare that with roughly $30 billion that the U.S. government annually spends on health research and $80 billion on defense research and development.
