I was all set to buy one of these, and I was looking at the picture trying to figure out whether the slots were wide enough for bagels, when someone pointed out that the skull would be over the bagel-hole.

"Dinosaurs probably had tapeworms too, and we can only wonder how long they got."


"Some monogeneans give birth to offspring without releasing them from their bodies. Their offspring mature inside them and give birth as well. Like a hideous Russian doll, a monogenean may contain twenty generations of descendents inside its body!"

magical electricity

The Prophet of Garbage

It sounds as if someone just dropped a tricycle into a meat grinder. [...] Inside a sealed vessel, a 650-volt current passing between two electrodes rips electrons from the air, converting the gas into plasma. Current flows continuously through this newly formed plasma, creating a field of extremely intense energy very much like lightning. The radiant energy of the plasma arc is so powerful, it disintegrates trash into its constituent elements by tearing apart molecular bonds. The system is capable of breaking down pretty much anything except nuclear waste, the isotopes of which are indestructible. The only by-products are an obsidian-like glass used as a raw material for numerous applications, including bathroom tiles and high-strength asphalt, and a synthesis gas, or "syngas" -- a mixture of primarily hydrogen and carbon monoxide that can be converted into a variety of marketable fuels, including ethanol, natural gas and hydrogen.

Perhaps the most amazing part of the process is that it's self-sustaining. Startech's Plasma Converter draws its power from the electrical grid to get started. The initial voltage is about equal to the zap from a police stun gun. But once the cycle is under way, the 2,200F syngas is fed into a cooling system, generating steam that drives turbines to produce electricity. About two thirds of the power is siphoned off to run the converter; the rest can be used on-site for heating or electricity, or sold back to the utility grid.

(I'm not sure I understand how that last part doesn't violate the second law of thermodynamics...)

"We'll get all our garbage to disappear, and our landfill will be gone in 20 years," he tells me. "We'll generate 160 megawatts a day from the garbage, but we'll consume only 40 megawatts to run the plant. We'll sell the net energy to the local power grid." [...]

"All the landfills around New York have closed, incinerators are banned, and we are trucking our trash to Virginia and Pennsylvania," he explains. "That is costing the city $400 million a year. We could put seven or eight of these converters in the city, and that would be enough." [...] But the decision-making bureaucracy can be slow, and it is hamstrung by the politically well-connected waste-disposal industry. "Many landfill operators are used to getting a million dollars a month out of debris," says U.S. Energy's Paul Marazzo. "They don't want a converter to happen because they'll lose their revenue."

(By "the politically well-connected waste-disposal industry" I'm pretty sure they mean Tony Soprano.)

Researchers convert heat to electricity using organic molecules, could lead to new energy source

Researchers at the University of California, Berkeley, have successfully generated electricity from heat by trapping organic molecules between metal nanoparticles, an achievement that could pave the way toward the development of a new source for energy.

The discovery is a milestone in the quest for efficient ways to directly convert heat into electricity. [...] "Generating 1 watt of power requires about 3 watts of heat input and involves dumping into the environment the equivalent of about 2 watts of power in the form of heat. If even a fraction of the lost heat can be converted into electricity in a cost-effective manner, the impact it would have on energy can be enormous, amounting to massive savings of fuel and reductions in carbon dioxide emissions."

More Teeth Means More Human

Teeth: a future renewable natural resource?

Most vertebrates have continuous tooth generation, meaning that lost teeth are replaced with new teeth. Mammals, however, including humans, have teeth that are generally only replaced once, when milk teeth are replaced with permanent teeth.

Researchers have now shown that continuous tooth generation can be induced in mammals. [...] As a result of stimulating this particular signalling, one mouse molar developed dozens of new teeth with normal dentin, tooth enamel and developing roots. The crowns were, however, simple and cone-shaped, unlike the typically more complex multiple cusps of mouse molars. [...]

It is reasonable to conjecture that the potential for continuous tooth generation may also have been retained in humans. Who knows: perhaps dentists in the distant future may be able to use this million-year-old regenerative potential to make their patients grow new teeth to replace lost ones.

Oh, Internets, is there nothing you cannot provide?

Surprising things I have learned this morning include:

  • There a blog about lobsters. Just lobsters.
  • There are Lobster Activists who are concerned about cruelty to lobsters. And Whole Foods cares what they think. (Are people also concerned about cruelty to cockroaches? Because they're basically the same thing.)

  • This is what a deliciously naked lobster looks like (See also "boneless chicken ranch"):

  • You do that with a hyperbaric chamber:

The Secret Life of Lobsters: food and sex:

You press the start button on an Avure machine. Powerful pumps whir, and inside a narrow tube in the center of the machine, the water pressure is compressed to several times the pressure found in the deepest trenches in the ocean. The microscopic bugs in your meal all die, giving the food extended shelf life, and reducing the need for artificial preservatives.

The animals are locked inside the tube, alive, and the pumps whir and the water pressure is compressed around the lobsters to three times the deepest trenches in the ocean. The lobsters die, of course -- just think what the pressure on your ears is like when you dive a few feet underwater.

At the same time, all the muscle flesh inside the lobsters conveniently separates from the shell. For the first time in human history, people have finally devised way to extract the meat of a lobster without cooking it.

Hooray for the Internets. And for delicious giant bugs.
