Science fiction: the good and the bad | Bad Astronomy

DM_cover_winter2009If you’re out shopping today and happen to pass your friendly neighborhood newsstand, then may I suggest you pick up a copy of the winter special issue of Discover Magazine? The theme is "Extreme Universe", with articles about the Big Bang, quantum mechanics, particle physics, and lots more.

Of course, included in that "lots more " is, well, me. I wrote the introductory essay to the issue, and also have a list of my favorite good and bad science moments in movies. The Hive Overmind Discover Magazine has a gallery up, too, with pictures and my descriptions of the movies.

I was surprised how hard it was to make the list, given a) I’ve seen almost every science fiction movie ever made, and 2) you’d think examples would abound. But finding specific scenes turned out to be tough, also given the criterion that it has to be in a movie lots of people have actually seen; calling out the lava flow sequence in "Voyage to the Prehistoric Planet" (1965) won’t get you terribly far. But I think I did OK.

Got a favorite bad or good scene in a movie? Discuss.


Neuron connections seen in 3D

A team of researchers from the Max Planck Institute of Biochemistry, in Germany, led by the Spanish physicist Ruben Fernandez-Busnadiego, has managed to obtain 3D images of the vesicles and filaments involved in communication between neurons.

Quantum information processing – lifting the big veil

The QIP (International Workshop on Quantum Information Processing) is a major meeting point for quantum theorists. Renato Renner, an assistant professor of theoretical physics at ETH Zurich and co-organizer of this year's convention, explains why we will be contemplating application programs over the next few days even though we are still a far cry from a universally operational quantum computer.

How the Tobacco Plant Outwitted the Hawkmoth | 80beats

tobaccoIt always helps to have good timing. And no one seems to understand that better than the tobacco plant Nicotiana attenuata, which grows in Western United States and flowers at night [The New York Times]. Normally, the tobacco plant is pollinated by hawkmoths that visits its flowers every night. But when these hawkmoths leave eggs behind that develop into leaf-chomping caterpillars, the plant’s self-defense snaps into place and switches to flowering in the day. That attracts a different pollinator, the hummingbird.

Ecologist Danny Kessler noticed this change when he was trying to get a picture of the plant being pollinated for a study. He saw that the plant was not just flowering in the day but also that they had changed their flowers to make them more attractive to hummingbirds: they emitted less of a chemical that attracts moths; they had less sugar in the nectar, which is the way hummingbirds prefer it; and they were more tube-shaped, making them friendly to a hummingbird’s long, thin beak [ScienceNOW Daily News].

Kessler and his colleagues at the Max Planck Institute, including ecologist Ian Baldwin, wondered if this change of flowering time and pollinator had anything to with being eaten by caterpillars. They decided to check it out. He [Kessler] put caterpillars on plants that had not been attacked and found that after 8 days, 35% of their flowers opened in the morning–compared with 11% on unmolested plants. Plants responded the same way when Kessler wounded the leaves and put caterpillar spit on them [ScienceNOW Daily News]. Their results were published in Current Biology.

The researchers said the plant’s responses show it remains hyper-alert for voracious caterpillars, while other scientists note that these alterations suggest that plants can adapt their flowers to suit changing conditions. It also makes us think differently, say the researchers, about how to deal with pests that attack plants. Instead of just spraying bug-spray, they point out that there may be other ways to deal with the problem–making a plant less attractive to the mothers of the predators, for example [ScienceNOW Daily News].

Asus DR-950 eBook Reader Gets Its Close-Up [Readers]

The announcement that Asus was getting into the eBook reader game was a bit of a surprise, but not an unwelcome one. Now that new hands-on pics have hit Flickr, it looks like our initial enthusiasm was founded.

What's most alluring about the DR-950 is still the thinness—just .35-inches despite the 9-inch, 1024×768 display.

It's also one of the first mass market black and white eBook reader's I've seen that doesn't use e-ink. Instead, Asus is using the unfortunately named SiPix Microcup electronic paper, which purports to be more a more energy efficient alternative.

Other specs include 2-4GB of storage, an SD card slot, Wi-Fi and HDSPA, a USB port and a 3.5mm headphone jack. Pricing and timing are still up in the air.

Honestly, there are a lot of these hitting the market these days, but given that pioneering Asus did in the early netbook days, we'll give them the benefit of the doubt that they're bringing something exciting. It certainly looks that way so far. [Asus UK Flickr via Engadget]

A Boeing 777 As Superman Would See It [Photography]

Nick Veasey is not superman, but he has one of his superpowers: X-Ray vision. Veasey spends his time taking stunning X-ray photographs, including this Boeing 777 and its twin GE90-115B turbofan engines, which took three months and 500 separate x-rays.

TED just posted this talk by Veasey, in which he explains how he does his stunning images:

Basically, a lot of patience, talent, and too much radiation in his own bones. [Nick Veasy via TED]


The Solar Powered Pod House Would Be The Ideal Blogger’s Home Office [Architecture]

If I had a backyard big enough for a home office, the MercuryHouseOne is what I'd be saving all my pocket money up for. It's a mobile solar-powered lounge, hard and space-age on the outside but warm and soft inside.

It was shown off recently at the Venice Biennale art exhibition by the Architecture and Vision design firm, and while it's not on sale I hope Ikea or another retailer can rip it off, err I mean, take inspiration from it. It's made from Italian Carrara marble, and the outer top half is covered with solar panels for powering up the inside. Check out the gallery below for more pics of this awesome space age playroom.

Owle Bubo Review: For Hardcore iPhone Videographers [Review]

Owle Bubo isn't an obscure Star Wars bounty hunter. It's a $130 billet aluminum iPhone case, complete with swappable 37mm macro lens. It's well-made, attractive, and makes iPhone video easy. But you probably don't want this one.

Products like the Bubo confuse my little retail suggestion brain. For some of you, $130 is a pittance to get a sturdy case with four female tripod mounts, a cold shoe for lights and microphones, and two comfortable handles that steady up your iPhone videography.

For others, $130 is nearly the price you paid for the phone itself—or the price of a decent Kodak or Flip video camera.

So Much Right

Let's start with what Owle gets right: The design—from packaging, to the physical feel of the Bubo in your hands, to the friendly instruction manual complete with jokes about Perez Hilton)—is excellent, especially considering it's Owle's first product.

The cool metal feels wonderful in your hands. The mounting points allow for nearly any combination of accessories, a quality I'd love to see emulated by other cameras and rail systems. (Consider that even most pro video cameras have a single tripod mount and a single hotshoe.)

Video quality is improved over the iPhone 3GS's default, simply by dint of the large glass lens that rests over the iPhone's sensor. It adds a slight fisheye effect, but one that is generally welcome, alleviating the typical claustrophobic feel of iPhone video.

Video Testing

But is it over a hundred dollars worth of improvement? Depends. Below I've embedded Owle's video they shot during CES that shows a side-by-side comparison of video with and without the Bubo.

Pretty good, right? Well, below are two videos I shot within seconds of each other of a mossy rock and then uploaded straight to Vimeo. Frankly, besides the wider lens and slight difference in sharpness, I'm hard pressed to see anything profoundly different.

So fine. It's better with Bubo, for sure, but not much. You can't judge the Owle Bubo without remembering that the power of its camera isn't that it's particularly high-quality, but that it's wedded to a phone with hundreds and hundreds of useful, fascinating apps that extend its capabilities to a fantastic degree. (It's hilariously true to say the iPhone is the most powerful camera in the world—if you discount image quality.)

Yet There Was A But

But a couple of things about the Bubo make me wary to recommend it quite yet.

It's heavy. Heavier than the iPhone on its own, certainly. Heavier than many "real" camcorders I've used. According to the box it shipped in—there's no weight information on Owle's website—it's just under two pounds before you put the iPhone in or mount any lights or microphones. On my light Manfrotto tripod, it kind of made it want to lean a little, although if everything was tightened properly it seemed to be fine. No big deal, but for handheld shots I could see it getting tiring. (Then again, all cameras are tiring after a while.)

The system for holding the iPhone in place scares me, too. You're forced to put your iPhone in a rubberized case. (One was included with my test sample, but several others from major case manufacturers are supported.) Then you jam that case into the back of the Bubo where it is held in place by tension alone. I never once had an issue where my iPhone started to slip out, but still...it's a bit scary. A simple flip-down tab would go a long way toward appeasing my fear of seeing the heart of my camera system go clattering to the concrete.

Finally: price. It's not too expensive for its level of quality—solid hunks of aluminum aren't cheap—but it does take it out of impulse purchase territory for most, which is a pity. A planned composite (read: plastic) version is in the works which Owle expects to sell for around $70. Considering the optics and tripod mounts will still be the same quality as the Bubo's, that seems like a fair price.

One final niggle I'd like to see improved in future versions: It would be nice to see a divot in the bottom tripod mounts for stabilizing pins, common on most tripods. That would help prevent the Bubo from potentially spinning itself out of the tripod screw during all-day use.
