Colossal explosion from supermassive black hole at center of galaxy revealed

September 25, 2013


Two million years ago, a supermassive black hole at the heart of our galaxy erupted in an explosion so immensely powerful that it lit up a cloud 200,000 light years away, a team of researchers led by the University of Sydney has revealed.

The finding is an exciting confirmation that black holes can “flicker,” moving from maximum power to switching off over short periods of… read more

Colossal Cosmic Collision Reveals Mysterious Dark Matter

August 22, 2006
Galaxy cluster 1E0657-556: dark matter is not seen, but its gravity affects how the light from each background galaxy is distorted

New observations of a great big cosmic collision provide the best evidence yet that invisible and mysterious dark matter really does exist.

Colorado senator calls for space-based interceptors

April 9, 2008

Sen. Wayne Allard (R-Colo.) called Tuesday (April 8) for the addition of a “space-based layer of interceptors for ballistic missile defense” in his opening keynote at the National Space Symposium.

University of Southampton neuroscientists have developed a method called “multicolor RGB tracking” to improve our understanding of how the brain works by color-marking individual brain cells in mice allows them to be tracked over space and time.*

To mark a brain cell, they inject a solution that contains three viral vectors (delivery of genes by a virus) to create a fluorescent protein in each cell. Each cell… read more

Color red increases the speed and strength of reactions

June 3, 2011

Color Red

Researchers at the University of Rochester have determined that when humans see the color red, their reactions become both faster and more forceful.

The researchers measured the reactions of students in two experiments. In the first, 30 fourth-through-10th graders pinched and held open a metal clasp. Right before doing so, they read aloud their participant number written in either red or gray crayon.

In the… read more

Color Quantum-Dot Displays

(Bulovic group, MIT)

In a crucial step in the development of color quantum-dot displays, QD Vision is developing rubber stamps to deposit quantum dots–tiny light-emitting crystals–on a surface.

The technique lets them put rows of different-colored dots next to each other, allowing for displays that promise to be thinner, more flexible, brighter, sharper, and more power efficient than flat-panel LCDs.

Affordable displays based on the technique could be on… read more

Color E-Paper That Rivals the Real Thing

Prototype in-plane electrophoretic display (Philips)

A new approach to electrophoretic displays being developed by Philips Research — moving pixels horizontally instead of vertically — may finally mean high-quality color electronic paper.

Color Comes to E Ink Screens

November 8, 2010


On Tuesday at the FPD International 2010 trade show in Tokyo, Hanvon, a Chinese company, will announce that it will be the first to sell a color display using technology from E Ink, whose black-and-white displays are used in 90 percent of the world’s e-readers.

The new color E Ink display  is not as sharp and colorful as LCD, and cannot handle full-motion video.

Hanvon’s first product… read more

Colon cancer stem cells identified

November 21, 2006

Scientists have identified a population of human colon cancer stem cells that can initiate tumor growth and differentiate into mature tumors, according to two reports in Nature.

These cells, representing just two to three percent of the overall tumor, should be the focus of cancer therapies, according to Ruggero De Maria, research director, Department of Hematology and Oncology, Istituto Superiore di Sanita, Rome, who led one of the two… read more

Colloidal microparticles that self-assemble into novel 3D structures

Could lead to photonic crystals that improve displays and computer chips

Researchers from NYU, Harvard, and Dow Chemical have created new colloidal microparticles that spontaneously self-assemble into structures resembling molecules made from atoms.

These structures were previously impossible to make and hold promise for manufacturing advanced optical materials and ceramics, such as photonic crystals that could improve displays and computer chips.

The method was developed by a team of chemists, chemical engineers, and physicists at New York University (NYU), the Harvard School of… read more

Collision in the making between self-driving cars and how the world works

January 26, 2012

Robot Car

Questions of legal liability, privacy and insurance regulation self-driving vehicles have yet to be addressed, and such challenges might pose far more problems than the technological ones.

Should the police have the right to pull over autonomous vehicles?

Human drivers frequently bend the rules by rolling through stop signs and driving above speed limits; how would a polite and law-abiding robot vehicle fare against such competition?

What… read more

Collision Course: Beating Moore’s Law by 2006 will take teamwork

February 15, 2002

CERN’s Large Hadron Supercollider will begin generating more than 10 million gigabytes of data each year when it becomes operational in 2006 — beyond the capabilities of any computer CERN scientists had at their disposal, or any supercomputer that could be built. The solution: the European DataGrid.The European DataGrid is an ambitious project based on an emerging distributed-processing technology known as grid computing. Instead of relying on mainframe makers like… read more

Colliding Particles Can Make Black Holes

January 25, 2010

Princeton University scientists have calculated the gravitational interactions between colliding particles modeled as black holes and found that a black hole formed if two particles collide with a total energy of about one-third of the Planck energy.

While the Planck energy is a quintillion times higher than the LHC’s maximum, if space actually has more dimensions (predicted by certain theories) that are curled into little loops too small to… read more

Colleges see the future in technology

September 13, 2006

Cutting-edge videogame and artificial intelligence technology are on the way to provide more individualized instruction.

Some of the most futuristic devices could even monitor students’ brainwaves to keep track of how they’re learning.

College for all? Experts say not necessarily

May 17, 2010

With rising student debt, stagnant graduation rates, a struggling job market flooded with overqualified degree-holders, and unemployment rate for college graduates trailing the rate for high school graduates, the notion that a four-year degree is essential for real success is being challenged by a growing number of economists, policy analysts and academics.
