Hackers Slow Internet Root Servers With Attack

February 7, 2007

Using a botnet, online attackers disrupted service Tuesday on at least two of the 13 “root” servers that are used to direct traffic on the Internet.

The two hardest-hit servers are maintained by the U.S. Department of Defense and the Internet Corporation for Assigned Names and Numbers (ICANN).

Saudi Arabia unveils grand supercomputer ambitions

September 26, 2008

Saudi Arabia plans to build a petascale supercomputer system in two years that could rank among the 10 most powerful systems in the world, and beyond that, an exascale system (1000 times as fast as petascale).

Code-named Shaheen (Peregrine Falcon), it is being built by IBM, based on the Blue Gene/P System, and will intially run at 222 teraflops. It will be located at King Abdullah University of Science… read more

Molecular logic proposed

March 26, 2004

Researchers have devised a scheme for designing logic circuits by connecting a pair of benzene molecules to two gold electrodes.

The scheme could eventually be used to produce small, fast computers and store large amounts of data in very small spaces.

Lithium market could bloom as tide goes out on oil

June 23, 2010

Frost and Sullivan says the lithium-ion battery market for electric and hybrid vehicles is set to grow from 2,400 units in 2008 to 1.53 million units by 2015.

Breaking fish advice during pregnancy might benefit babies

February 15, 2007

Women who follow government guidelines and eat no more than three portions of fish a week during pregnancy increase the risk of their children developing poor verbal and social skills, a new study by the National Institutes of Health suggests, because omega-3 fatty acids in fish appear to promote brain growth during fetal development.

In 2004 the US Environmental Protection Agency and FDA jointly advised pregnant and nursing women… read more

Scientists identify a molecule that coordinates the movement of cells

October 3, 2008

Scientists at the Howard Hughes Medical Institute and Rockefeller University have found that a molecule, called ACF7, helps regulate and power the cell’s movement along the extracellular matrix from the inside — findings that could have implications for understanding how cancer cells metastasize.

They found that ACF7 is an orchestrator of directed cellular movement by guiding microtubules along a roadway of actin cables, leading them toward focal adhesions at… read more

MRI with 80-nm resolution

April 12, 2004

An MRI with 80-nm resolution has been achieved with a device that combines atomic force microscope (AFM) and MRI technology.

The device is intended to scan and image small objects — especially particles of biological importance, such as viruses and proteins — with atomic-scale resolution.

The best medical MRI has a spatial resolution of about a tenth of a millimeter.

First Direct Photo of Alien Planet Finally Confirmed

July 1, 2010

080915-exoplanet-01

A planet outside of our solar system, said to be the first ever directly photographed by telescopes on Earth, has been officially confirmed to be orbiting a sun-like star that is 500 light-years away.

Genetic privacy protected by law

February 26, 2007

The Genetic Information Nondiscrimination Act (GINA), introduced into Congress on January 16, if passed, will become the first federal law to prevent employers from collecting genetic information on their employees.

It would also outlaw genetic discrimination, preventing insurers from denying coverage or charging higher premiums based on a person’s predisposition to disease.

Mouse studies suggest daily dose of ginkgo may prevent brain cell damage after a stroke

October 10, 2008

Researchers at Johns Hopkins have shown that daily doses of a standardized extract from the leaves of the ginkgo tree can prevent or reduce brain damage after an induced stroke in mice, and if confirmed for humans “could theoretically recommend a daily regimen of ginkgo to people at high risk of stroke as a preventive measure against brain damage.”

Sony develops paper-based disc

April 19, 2004

Sony and Tappan have announced a new Blu-Ray-based disc capable of holding 25 GB. It uses 51 percent paper, replacing a polycarbonate plastic substrate.

The new disc promises to be more environmentally friendly and secure when destroyed than traditional discs.

Darwin’s God

March 5, 2007

In the world of evolutionary biology, the question is not whether God exists but why we believe in him. Is belief a helpful adaptation or an evolutionary accident?

Study finds value in ‘junk’ DNA

October 17, 2008

A University of Iowa study has found evidence that a significant number of exons (the building blocks for protein-coding genes) created from junk DNA seem to play a role in gene regulation.

Google’s Goal: “Understand Everything”

April 27, 2004

“The ultimate search engine would basically understand everything in the world, and it would always give you the right thing,” says Google co-founder Larry Page. “Our mission is to organize the world’s information.”

Picture puzzles separate human from machine

July 15, 2010

(National Cheng Kung University)

Researchers at National Cheng Kung University in Taiwan have developed a tool that camoflages images and could be used to make Captcha images, to ensure that website users signing up for accounts are genuinely people, rather than software bots.

The work fits with the theory that the brain can only be conscious of one visual feature at a glance, but can track the locations of multiple features simultaneously.… read more
