A type of X-ray explosion found on neutron stars does not occur near black holes, scientists announced at the 207th meeting of the American Astronomical Society.

The lack of explosions is strong evidence for the existence of a black hole event horizon, a theoretical boundary into which matter vanishes and cannot escape.

Researcher leads international effort to create ‘proteinpedia’

February 8, 2008

A Johns Hopkins Institute of Genetic Medicine researcher is leading an effort to compile to date the largest free resource of experimental information about human proteins.

Their “proteinpedia” currently compiles data provided by more than 71 laboratories with entries for more than 15,230 human proteins.

‘Nanowire’ Breakthrough

April 2, 2003

Microscopic wires which could help form the miniature technology of the future have been constructed using the basic building blocks of living things.

Memristor minds: The future of artificial intelligence

July 8, 2009

Hybrid transitor-memristor chips designed to reproduce some of the brain’s thought processes have been developed by HP and Boston University researchers, and University of California, San Diego researchers have developed a memristive device that they claim behaves like a neural synapse.

This Is Your Brain on Schadenfreude

January 24, 2006

Functional magnetic resonance imaging has reached the level of sophistication required to identify states of mind, as shown in one recent experiment to measure levels of empathy, based on “pain-related areas” in the brain when a person is watching someone else in pain.

Understanding the science for tomorrow: myth and reality

January 3, 2012

Understanding the science for tomorrow

In 24 video lectures on Understanding the Science for Tomorrow: Myth and Reality, Jeffrey C. Grossman, a research scientist and professor at University of Illinois at Urbana-Champaign and MIT, presents a “scientifically accurate and enlightening survey of today’s most advanced research” in fields such as engineering, biology, chemistry, and theoretical physics, including nanotechnology, quantum computing, genetic engineering, and AI.

More Brain Research Suggests ‘Use It Or Lose It’

February 13, 2008

Queensland Brain Institute scientists have found another clue to why nerve cells die in neurodegenerative diseases, adding more weight to the “use it or lose it” model for brain function.

A baby’s brain generates roughly double the number of nerve cells it needs to function. Cells that receive chemical and electrical stimuli survive, the remaining ones die.

Games to take your breath away

April 18, 2003

Scientists at Dublin’s Media Lab Europe have developed a computer game uses sensors stuck to a player’s body.

“The sensors monitor breathing and only move characters on-screen if the player breathes in the right way. The game is designed for children in hospital to help them cope with boredom during long periods of bed rest and recuperation.

Better Vision, With a Telescope Inside the Eye

July 20, 2009

A tiny telescope, already approved for use in Europe, can be implanted in one eye, replacing the natural lens, to help people with an advanced form of macular degeneration.

DNA Kits Aim to Link You to the Here and Then

February 6, 2006

DNA testing promises to provide genetic information to uncover details about one’s heritage.

More than a dozen companies now sell home DNA tests; the prices range from $100 to $900 each.

consumers also receive a document with their DNA string of markers, which looks like a list of numbers, and a report that explains how to make sense of it.

That data, however, needs to be compared… read more

Stress hormone impacts memory, learning in diabetic rodents

February 18, 2008

A National Institutes of Health study finds increased levels of the stress hormone cortisol temporarily disrupts healthy hippocampus functions in diabetic rats, a step in understanding why diabetes impairs the cognitive health of people.

Both Type 1 and Type 2 diabetic rats exhibited learning and memory deficits when cortisol levels were elevated due to impaired plasticity and declines in new cell growth.

Anthrax genome decoded

May 1, 2003

The complete genetic blueprint of Bacillus anthracis has been published in the May 1 issue of Nature.

The researchers found a number of genes encoding proteins that B. anthracis may need to enter its host’s cells. These could provide targets for drugs designed against the organism.

Cheaper Solar Thermal Power

July 28, 2009

Stirling Energy Systems has designed a new simplified, low-cost system for focusing sunlight on a Stirling engine to generate electricity.

The company expects electricity from the systems to cost between 12 and 15 cents per kilowatt hour, and has contracts with two California utilities to supply a total of 800 megawatts of solar power in Southern California.

Evanescent wave litho to surface at SPIE

February 17, 2006

The Rochester Institute of Technology (RIT) is expected to present a paper that claims it has produced a 26-nm image based on evanescent wave lithography (EWL).

This, in turn, opens EWL as an extension to conventional projection lithography as a means for sub-32-nm chip production, according to RIT.

Going by the book
