Recent Interesting Science Articles (July 2008)

Leave a comment

I haven’t been as up to date as I should this month, but nonetheless I have three articles. The first and the most exciting one is the announcement by NASA confirming the presence of water on Mars. Now, we’ve had indirect evidence of water for a while now, but this is the first time that a robot, in this case the Phoenix, has actually tasted it by melting a piece of ice. The next step will be to bring it to even higher temperatures to try to find any traces of carbon-based compounds.

Recent Interesting Science Articles (June 2008)

Wow, I haven’t done any updates for this in a while, so let’s make up for it by posting about four different articles, starting with the biggest science-related news this month. According to the U.S. National Snow and Ice Center, the North Pole may be, for a brief period, completely free of ice this summer. This is as alarming a symptom of global warming as anyone can imagine. While the scientists assure us that the melting of the polar ice cap should have no immediate ill effects, jokes about Santa Claus losing his home aside, it’s hard to deny that this should be seen as an extremely loud wake up call.

I have to admit that I was once a global warming skeptic myself but the scientific consensus now is that global warming is a real and human-induced phenomenon. What we should do about it is a different and complex matter of course, and I still reserve the right to mock greens for their conflicting rhetoric over it.

A Film: The 11th Hour

Leave a comment

Courtesy of my friend Kien Boon of Boonuhkau, I had the opportunity of watching The 11th Hour at the KL Pac in Sentul on Sunday. It was my first visit to the KL Pac or even anywhere inside the new Sentul development zone and I have to admit that they did a great job in making the area look like an oasis of serenity in the middle of busy and dirty Kuala Lumpur. The price to pay of course is the prominent advertising everywhere on behalf of YTL Corporation, including brightly illuminated banners on both sides of the stage that remained lighted throughout the film and that we felt detracted from the experience of watching it. Nevertheless, it’s heartening to see a new addition to the cultural scene in Malaysia and my wife and I will be paying attention to what performances are going on there from time to time.

The film itself is a slickly produced documentary on environmentalism, focusing on global warming, that was apparently a personal project of Leonardo DiCaprio. As a long time skeptic on environmentalism, it shouldn’t be a surprise that I strongly disliked the film. Not only is it an example of hysterical scare-mongering of the worst sort, it ends up being inconsistent in its message and ultimately contributes nothing new to the subject. Worst of all, it preaches straight to the choir of the green movement, shying away from perspectives and solutions that could be beneficial but are controversial and unpopular among green groups.

Recent Interesting Science Articles (Mar’08)

Four articles this month, one on the extremely exciting findings by the Cassini-Huygens mission to Enceladus, one on a somewhat weird life form found inside the remains of the Chernobyl nuclear reactor and finally two somewhat similar cases of emerging risks to people with medical conditions, one due to the use of implanted medical devices and the other due to exploits on Internet web browsers.

The Cassini-Hugens mission to Enceladus, the sixth largest of Saturn’s moons, not only confirmed the presence of liquid water beneath the icy surface of the moon, but also discovered, from a sampling of the brew vented out by a geyser the spacecraft flew past, that the moon is extraordinarily active and contains a surprising mix of organic chemicals. As the press release notes, heat, water vapour and organic compounds are the basic building blocks for life. As a science geek, I’m also impressed by the technical achievement of flying so close by a small moon at extremely high speeds, successfully intersecting a venting geyser without crashing on the moon with the whole thing carefully planned and coordinated on Earth.

Psionic Interface for Gamers

1 Comment

I tend not to write gushy posts about the latest tech toys because I don’t care for devices looking sleek or fashionable. To me, function matters a lot more than form. However, I’m writing about this latest interface device from OCZ because it’s cool enough to make for an exception. It’s called the Neural Impulse Actuator and it’s a headband that can “hear” your thoughts and allow you to use it to interface with a computer, replacing the traditional mouse and keyboard.

Devices like this aren’t exactly news at this point, but this is the first time that I’ve heard of something like this outside of an experimental setting with specially designed software. OCZ’s device has already been demoed at a computer show to play a commercial FPS game, Unreal Tournament, and apparently will soon be in normal production with an estimated retail price of US$300.00. The makers also claim that since the device bypasses the muscles, response time for gamers will be much better. Essentially, instead of your thoughts going to your fingers and from there to the computer, they’ll pretty much go directly from your brain to the computer.

We’ll have to wait a while yet to see how much of this is true and how sophisticated an input device it proves to be. It seems to me that an important factor will be the communications bandwidth that it allows between your brain and the computer. If the bandwidth is large enough, it would cause a revolution in games design since it would allow games with many more options and controls to be designed than would normally be possible given the physical control limits of traditional interfaces.

Four articles this month, one on how behavior in robots can “evolve”, one on a new way of using stem cells, one on a controversial device to disperse teenaged loiterers in the U.K. and a last one on the creation of a material blacker than any previously known.

In the first article, researchers at the Swiss Federal Institute of Technology have created learning robots outfitted with light sensors, light rings and a neural circuitry of 30 “genes” that together determine their behavior. These robots were then placed in a specially designed habitat with designated areas containing either “food” or “poison” that charged or drained their batteries respectively. The “genes” from the survivors of each round, together with some randomness to simulate mutation, were recombined to form a new generation of robots that were again set loose in the habitat. By the 50th generation, some of the robots had evolved the ability to communicate with each other, lighting up to alert other robots to the presence of food or poison and even learned to cheat by signaling food where there is really poison and quietly “eating” the food by itself.

China Controls the Weather

1 Comment

I’ve previously read that China intends to make sure that nothing, not even rain, will get in the way of its coming out party that is the 2008 Olympics at Beijing, but even I’m surprised to learn to learn of the colossal scale of their plans. The purpose built stadium for the Olympics, the Beijing National Stadium, is open to the elements, so the Chinese government has decided to implement weather modification technology that reduces the size of the raindrops over the stadium so they won’t condense and fall to the earth until after the clouds carrying them have passed by the stadium. In order to accomplish this, China is marshaling the full resources of its 37,000 strong bureau of weather modification together with 30 aircraft, 4,000 rocket launchers and 7,000 antiaircraft guns to get the necessary chemicals into the air around the stadium.

The science geek in me is amazed by the audacity of the Chinese government to impose their own weather according to their will but I’m also concerned about the possible environmental consequences of such drastic actions. Needless to say, this sort of thing will never be possible in Western countries for it’ll quickly whip up a firestorm of environmental protests and liability lawsuits over even imagined ailments from the fallout.
