Items for students and others, interested in learning about science and engineering and the application of science in our lives. We post many of the general interest items here.

$10 Million X Prize for DNA Decoding

X Prize for Genomics

The $10 million X PRIZE for Genomics prize purse will be awarded to the first Team that can build a device and use it to sequence 100 human genomes within 10 days or less, with an accuracy of no more than one error in every 10,000 bases sequenced, with sequences accurately covering at least 98% of the genome, and at a recurring cost of no more than $10,000 per genome.

Teleportation Science

First Teleportation Between Light and Matter

The goal was to transfer, or teleport, the quantum state of a second light beam onto the cloud.

To do so, the group mixed a second, weaker laser pulse with the strong laser and split the superimposed beams into two arms. A detector in one arm measured the sum of the beams’ amplitudes and a detector in the second arm measured the difference between their phases.

Not exactly Star Trek… yet… 🙂

Scientists teleport two different objects

Monarch Travels

Fly Away Home:

The butterfly that goes from Canada to Mexico and partway back lives six to nine months, but when it mates and lays eggs, it may have gotten only as far as Texas, and breeding butterflies live only about six weeks. So a daughter born on a Texas prairie goes on to lay an egg on a South Dakota highway divider that becomes a granddaughter. That leads to a great-granddaughter born in a Winnipeg backyard. Come autumn, how does she find her way back to the same grove in Mexico that sheltered her great-grandmother?

A great question and interesting science. Students can help track the monarchs and other migrating species (bald eagles, robins, hummingbirds, whooping cranes…).

To test their ability to reorient themselves, Dr. Taylor has moved butterflies from Kansas to Washington, D.C. If he releases them right away, he said, they take off due south, as they would have where they were. But if he keeps them for a few days in mesh cages so they can see the sun rise and set, “they reset their compass heading,” he said. “The question is: How?”

Nobel Prize in Chemistry – 2006

Roger Kornberg, Stanford University, has recieved the 2006 Nobel Prize in Chemistry for his studies of the molecular basis of eukaryotic transcription.

Forty-seven years ago, the then twelve-year-old Roger Kornberg came to Stockholm to see his father, Arthur Kornberg, receive the Nobel Prize in Physiology or Medicine (1959) for his studies of how genetic information is transferred from one DNA-molecule to another. Kornberg senior had described how genetic information is transferred from a mother cell to its daughters. What Roger Kornberg himself has now done is to describe how the genetic information is copied from DNA into what is called messenger-RNA. The messenger-RNA carries the information out of the cell nucleus so that it can be used to construct the proteins.

The Nobel Prize organization provides more information (foolishly the Nobel site broke the link so I have removed it – when will people learn to do a decent job of running a web site?) on his work:

Discoveries by Accident

‘Failed’ experiment produces a bacterial Trojan horse by Katie Weber. Interestingly the usefulness of Penicillin, the most popular bacteria fighting agent, was discovered by accident (and then a smart scientist learning from the accident and applying that knowledge to creating an incredibly useful medication).

As he was puzzling out why what should have been a routine procedure wouldn’t work, he made a discovery that led to the creation of a new biological tool for destroying bacterial pathogens – one that doesn’t appear to trigger antibiotic resistance.

The discovery also led to the startup of a promising new biotechnology firm that has already brought Wisconsin a dozen new, high-paying, highly skilled jobs.

This is yet another example of the power of scientists and engineers to boost the economy and society at large.

2006 Nobel Prize in Physics

The Nobel Prize in Physics for 2006 goes to: John C. Mather, NASA Goddard Space Flight Center and George F. Smoot, University of California at Berkeley. More information, the Nobel Prize does an excellent job of providing additional details to the public. Other award programs, grant providers, museums, science societies… should learn from them, this is the right way to promote science and engineering in an internet age.

The experiment for which George Smoot was responsible was designed to look for small variations of the microwave background in different directions. Minuscule variations in the temperature of the microwave background in different parts of the universe could provide new clues about how galaxies and stars once appeared; why matter in this way had been concentrated to specific localities in the Universe rather than spreading out as a uniform sludge. Tiny variations in temperature could show where matter had started aggregating. Once this process had started, gravitation would take care of the rest: Matter attracts matter, which leads to stars and galaxies forming. Without a starting mechanism however, neither the Milky Way nor the Sun or the Earth would exist.

What Kids can Learn

This is a fascinating interview discussing what children can learn if given a computer and little, if any, instruction. Very Cool. Links on the progress since this interview are at the end of the post.

Q: This is your concept of minimally invasive education?

A: Yes. It started out as a joke but I’ve kept using the term … This is a system of education where you assume that children know how to put two and two together on their own. So you stand aside and intervene only if you see them going in a direction that might lead into a blind alley.

The interview explores what happened when:

Mitra simply left the computer on, connected to the Internet, and allowed any passerby to play with it. He monitored activity on the PC using a remote computer and a video camera mounted in a nearby tree.

What he discovered was that the most avid users of the machine were ghetto kids aged 6 to 12, most of whom have only the most rudimentary education and little knowledge of English. Yet within days, the kids had taught themselves to draw on the computer and to browse the Net. Some of the other things they learned, Mitra says, astonished him.

50 New Species Found in Indonesia Reefs

“Walking” Sharks Among 50 New Species Found in Indonesia Reefs

The sharks are about 3 to 4 feet (1 to 1.2 meters) long and walk along the shallow reef flats on their fins, preying on shrimp, crabs, snails, and small fish.

“If they get spooked they can swim away, but the thing that stands out is their walking over the bottom,” Troeng said.

The photo is of one of two species of walking sharks found. See video of the sharks and of more of the species found in Indonesia.
