Concepts of Intelligence

• Próximamente en español, Conceptos de Inteligencia; A collection of essays, anecdotes, and poetry sure to delight and challenge the mind."
• "Concepts..." is a tough book to put down; a melange of serious thinking and humor. (15)


Seeing the music in nature
MIT News Office    Share    Share on FacebookTwitterShare on LinkedinE-mail article
From spider webs to tangled proteins, Markus Buehler finds the connections between mathematics, molecules and materials. If anyone were going to discover the connections between molecular structures, mathematical concepts and musical scores, it's not surprising that Buehler would be the one. He has built his career on bridging the connections between disparate disciplines, asking simple questions as an approach to understanding the world. More

Defying conventional wisdom, water can float on oil
Science Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Defying thousands of years of conventional wisdom, scientists are reporting that it is possible for water to float on oil, a discovery they say has important potential applications in cleaning up oil spills that threaten seashores and fisheries. Their report appears in ACS' journal Langmuir. Chi M. Phan and colleagues point out that the ancient Greek philosopher Aristotle made an early attempt to explain flotation around 350 B.C. More

Programmable nanomedicine cancer treatment shrinks human tumors
Scientific American    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Chemotherapy treatment for cancer is a nasty process. Doctors must try to give patients just enough of the toxic drugs to kill off cancer cells without doing too much harm to the rest of the body's healthy tissues, a balancing act that, even if successful, can nevertheless cause horrible side effects. But what if you could program the harsh medicine to go only to the cancerous cells, sparing the rest of the body? More

Mind games: Sometimes a white coat isn't just a white coat
The New York Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
If you wear a white coat that you believe belongs to a doctor, your ability to pay attention increases sharply. But if you wear the same white coat believing it belongs to a painter, you will show no such improvement. So scientists report after studying a phenomenon they call enclothed cognition: the effects of clothing on cognitive processes. More

Self-sculpting sand
MIT News Office    Share    Share on FacebookTwitterShare on LinkedinE-mail article
New algorithms could enable heaps of "smart sand" that can assume any shape, allowing spontaneous formation of new tools or duplication of broken mechanical parts. Imagine that you have a big box of sand in which you bury a tiny model of a footstool. A few seconds later, you reach into the box and pull out a full-size footstool: The sand has assembled itself into a large-scale replica of the model. More

iBrain headband could one day read your mind
Daily Mail    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Professor Stephen Hawking is testing a tiny device that could possibly allow him to speak again — reading his thoughts directly from his brain. The gizmo, invented by Dr. Philip Low, CEO of California-based NeuroVigil, was designed for sleep monitoring, but it may also be able to help people to convey messages merely by thinking them. The device reads brain wave patterns and has been tested by renowned physicist Professor Stephen Hawking, who is paralyzed by amyotrophic lateral sclerosis, or Lou Gehrig's disease. More

The most sensitive scale ever can measure the mass of one proton
Discover Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The smallest named unit in the metric system is the yoctogram, equal to 0.000000000000000000000001 grams. For a scale that can measure differences in mass as small as a yoctogram, which is on the order of the mass of a proton, physicists writing in Nature Nanotechnology turned to the wunderkind of nanotechnology: carbon nanotubes.

The anthropology of searching for aliens
Wired    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Before we can understand an alien civilization, it might be useful to understand our own. To help in this task, anthropologist Kathryn Denning of York University in Toronto, studies the very human way that scientists, engineers and members of the public think about space exploration and the search for alien life. From Star Trek to SETI, our modern world is constantly imagining possible futures where we dart around the galaxy engaging with bizarre alien races. More

"Lost" long-fingered frog found in Africa
National Geographic    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In a handy stroke of luck, scientists have rediscovered a "lost" African species: the Bururi long-fingered frog. Last seen in 1949, the 1.3-inch-long (3.2-centimeter-long) amphibian was found during a December 2011 biodiversity survey in the small central African country of Burundi, scientists announced in March.

Researchers unearth largest feathered dinosaur
Science    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Paleontologists have unearthed fossils of the largest feathered creature yet known, a 1.4-metric ton dinosaur that was an early cousin of Tyrannosaurus rex. The long, filament-like feathers preserved with three relatively complete skeletons of the newly described species provide direct evidence of extensively feathered gigantic dinosaurs. The discovery is controversial — and in some scientific circles, largely unexpected. More

Physicists control quantum tunneling with light for the first time
PhysOrg    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Particles cannot normally pass through walls, but if they are small enough, quantum mechanics says that it can happen. This occurs during the production of radioactive decay and in many chemical reactions as well as in scanning tunnelling microscopes. According to team leader, Professor Jeremy Baumberg, "The trick to telling electrons how to pass through walls, is to now marry them with light." More

Lightning directed by laser beams
NewScientist    Share    Share on FacebookTwitterShare on LinkedinE-mail article
It's not quite Zeus, but at least it's not entirely myth. Lasers have been used for the first time to trigger and divert lightning bolts. The idea of using a powerful laser to create a low-resistance path through the atmosphere — a virtual lightning rod — gained momentum in the 1990s. Lasers were developed that could generate terawatts of power for femtoseconds. More
