How to turn a block of Antarctic ice into a giant neutrino detector. “To turn the ice into a telescope, all you have to do is drill an array of 80 holes half a meter across by 2.5km deep using a very powerfull jet of hot water. Then lower a string of 60 optical detectors into each hole before they refreeze, conect them up to some powerful computer analysers and you are good to go.”
Biologically odd people are pushing the limits of what the human body is capable of. “In 2002, Lynne Cox swam to Antarctica, withstanding 32-degree water in only a swimsuit.”
Debate on the science of gender and science between Elizabeth Spelke and Steven Pinker. “On sex differences between men and women and how they may relate to the careers of women in science”.
The Swiss are putting a blanket on one of their glaciers to keep it from melting.
Frank Bruni on avant guard cuisine (also called molecular gastronomy).
Part three of three of Elizabeth Kolbert’s series on global warming for the New Yorker. This one’s all about what we can and are/aren’t doing about the situation.
Astronomers may have detected the formation of a black hole. “A faint visible-light flash moments after a high-energy gamma-ray burst likely heralds the merger of two dense neutron stars to create a relatively low-mass black hole.”
Mad Physics is a neat science education site run by a couple of high school students.
Pitching slow to a young child is actually worse than pitching a little faster. “When you throw something slowly to a child, you think you’re doing them a favour by trying to be helpful. Slow balls actually appear stationary to a child.”
The Oh-My-God particle is a proton with the energy of a slow-pitched baseball. And it’s moving so fast that after travelling for a year, it would only be a few nanometers behind a photon travelling at the speed of light.
“Fads, fashions and dramatic shifts in public opinion all appear to follow a physical law: one of the laws of magnetism”. “Michard and Bouchaud checked this prediction against their model and found that the trends in birth rates and cellphone usage in European nations conformed quite accurately to this pattern. The same was true of the rate at which clapping died away in concerts.”
Advancing scientific research means that chimeric animals are on the way. “In the case of human cells’ invading the germ line, the chimeric animals might then carry human eggs and sperm, and in mating could therefore generate a fertilized human egg. Hardly anyone would desire to be conceived by a pair of mice.”
Scientists at Princeton have made a crude computer out of bacteria. Earlier work showed “they could insert DNA into cells to make them behave like digital circuits [and] perform basic mathematical logic. The latest work expands this concept to vast numbers of bacteria responding in concert.”
The second of Elizabeth Kolbert’s three-part series on global warming for the New Yorker. This one’s about how relatively short-term climate change can affect entire civilizations.
A near perfect Einstein Ring found. Close galaxies can act as a lens for farther galaxies, focusing the distant light with an “Einstein Ring”.
An ivory-billed woodpecker, thought to be extinct since 1920, found alive in Arkansas. Ok, now rustle us up some passenger pigeons.
Part one of Elizabeth Kolbert’s three-part series on global warming for the New Yorker. “Disappearing islands, thawing permafrost, melting polar ice. How the earth is changing.”
Steven Johnson says watching TV makes you smarter. The argument is that media has had to get more cognitively challenging to hold the attention of viewers. Evolutionarily speaking, attention is the scarce commodity that creates competition here, driving adaptation in the direction of more social and narrative complexity to hold that attention.
And if you ever need to move the Earth, here’s how you might accomplish that. “The Earth is very big, moving very fast, and therefore very difficult to stop or even slow down.”
Forget how life will end, here’s a bunch of ways you can destroy the entire Earth. This is a really fun read: “keeping the strangelet stable is incredibly difficult once it has absorbed the stabilising machinery, but creative solutions may be possible.”
Ten scientists on how human life on earth might end (or be severely curtailed). Super volcanos, killer robots, viral pandemic, oh my!
Some bacteria in Africa beat Fermi to the first stable nuclear reactor on Earth by almost 2 billion years. The bacteria enriched the uranium into a critical mass and the flow of water through the reactor kept the reaction going for millions of years.
This biography of electricity — and of the men and women who had a hand in uncovering its inner workings — begins in the first moments after the Big Bang. Which is probably not where your high school textbook started its exploration of the subject, nor will you find many of the oftentimes surprising stories Bodanis uses to illustrate his tale.
The first mobile phone was developed in 1879? Thomas Edison, inventor of the light bulb, “had a vacuum where his conscience ought to be”? Alexander Graham Bell, in part, invented the telephone to impress a girl (well, acutally the girl’s parents)? Samuel Morse stole the telegraph from a guy named Joseph Henry and patented it, but not before he ran for mayor of New York City on an anti-black, anti-Jew, and, most especially, anti-Catholic platform? None of that was in my high school science textbook and such is the authority of the textbook that I have a hard time believing some of it. You’re thinking maybe Bodanis is embellishing for the sake of making a more exciting story (history + electricity? wake me when it’s over!), but then you get to the 50 pages of notes and further reading on the subject and realize he’s shooting straight and science is more strange, exciting, and sometime seedy than your teachers let on.
Poetry takes more brain power to read than prose. “Subjects were found to read poems slowly, concentrating and re-reading individual lines more than they did with prose.”
Life’s top ten greatest inventions. Includes the eye, sexual reproduction, photosynthesis, and language.
13 things that science doesn’t have the answers for. Dark matter, the Pioneer anomaly, cold fusion, the placebo effect, etc. Some great opportunities for discovery.
Update: New Scientist recently published a list of 13 more things that don’t make sense.
One of my favorite talks at Poptech was Janice Benyus’ presentation on biomimicry, or innovation inspired by nature:
Biomimicry is a new science that studies nature’s models and then imitates or takes inspiration from these designs and processes to solve human problems, e.g., a solar cell inspired by a leaf. [It] uses an ecological standard to judge the “rightness” of our innovations. After 3.8 billion years of evolution, nature has learned: What works. What is appropriate. What lasts. Biomimicry is a new way of viewing and valuing nature. It introduces an era based not on what we can extract from the natural world, but on what we can learn from it.
In the talk, Janine outlined 12 ways in which nature can inform the development of technology:
1. Self assembly
2. Chemistry in water
3. Solar transformations
4. The power of shape
5. Materials as systems
6. Natural selection as an innovation engine
7. Material recycling
8. Ecosystems that grow food
9. Energy savvy movement and transport
10. Resilience and healing
11. Sensing and responding
12. Life creates conditions conducive to life
Those are a little vague and I wish I’d written down more notes, but it was hard to type and really listen at the same time. To fill in the gaps, you can listen to the audio of her 30 minute presentation.
