The Flaw at the Heart of the Internet

October 22, 2008

Security researcher Dan Kaminsky first spotted a basic vulnerability in the Domain Name Service (DNS) for the Internet last winter.

Despite fixes, the vulnerability is still there for companies with unpatched servers.

Scots scientists unveil ‘spray-on’ computer

April 10, 2007

Scottish scientists have developed a computer the size of a matchstick head, thousands of which can be sprayed onto patients to give a comprehensive analysis of their condition.

The individual appliances, or “specks,” will form networks that can be programmed like ordinary computers.

Spraying them directly onto a person creates the ability to carry out different tests at the same time, for example muscle movement and pulse rate.… read more

Artificial Intelligence: Animation Finally Gets NextGen Technology

June 17, 2004

New animation technology applies artificial intelligence to character animation.

In video games, characters can learn to compete and make it more challenging for the user. In movies, animators can automate characters in scenes so they don’t have to tell each character what to do.

Azure: Can Microsoft Meld Windows with the Web?

October 28, 2008

Microsoft’s Windows Azure operating system, unveiled Monday, could give companies greater flexibility in using Windows, letting them run some programs on their own computer networks, extend their existing programs to the Web, or allow Microsoft to serve other tasks more effectively from its own massive data centers.

For example, Microsoft claims they can run e-mail programs for corporate customers in its own data centers for a fraction of the… read more

Biomaterial-delivered chemotherapy could effectively treat brain tumors

November 20, 2013

Polymer structure

A polymer originally designed to help mend broken bones could be successful in delivering chemotherapy drugs directly to the brains of patients suffering from glioblastoma brain tumors, researchers at The University of Nottingham have discovered.

Their study, published in the journal  PLOS ONE (open access), shows that the biomaterial can be easily applied to the cavity created following brain cancer surgery and used to release chemotherapy drugs over several… read more

Recording a Cell’s Dying Gasp

April 19, 2007

Scientists in the United Kingdom have developed a way to monitor the health of individual cells by recording ion flow down to the resolution of about 10 ions.

The technique could revolutionize the way we test drugs and carry out environmental sensing.

An array of semiconductor electrodes is spaced very close together to form a cross, upon which a cell is placed. The tip of an atomic force… read more

The (Nano) Arms Race Has Begun

July 2, 2004

India’s new President A. P. J. Abdul Kalam called today for India to develop nanotechnology — including nanobots — because it will revolutionize warfare.

He called for scientists to develop “super strong, smart and intelligent structures in the field of material science and this in turn could lead new production of nano robots with new types of explosives and sensors for air, land and space systems.”

“This is… read more

Study shows infectious prions can arise spontaneously in normal brain tissue

July 27, 2010

Scientists from The Scripps Research Institute in Florida and the University College London (UCL) Institute of Neurology in England have shown for the first time that abnormal prions, bits of infectious protein that can cause fatal neurodegenerative disease, can suddenly erupt from healthy brain tissue, promoted by contact with steel surfaces.

Mammalian cells normally produce harmless cellular prion protein (PrPC). Following prion infection, the abnormal or misfolded prion protein… read more

‘Cultured’ robots make sweet music together

November 4, 2008

Two robots that evolve a repertoire of melodies they can both sing could compose music beyond that of humans, says Eduardo Miranda, a composer and computer scientist at the University of Plymouth in the UK.

A New Dimension for Your Photos

April 27, 2007

A new Web service called Fotowoosh promises to convert photos into 3-D and serve as “a 3-D Flickr.”

The technology wsa developed by computer-vision researchers at Carnegie Mellon University.

‘High-rise’ chips sneak on market

July 15, 2004

“High-rise” three-dimensional semiconductors have quietly started making their way into consumer products.

Matrix Semiconductor is now selling its 3D memory/data storage chips, initially for use in storing pre-recorded content like games or songs.

In the company’s memory chips, planes of transistors can be stacked, which reduces the surface area of the chip and allows more chips to be produced from a single wafer. Ideally, manufacturers get the cost… read more

Recipes For Limb Renewal

August 5, 2010

Researchers at the Tufts Center for Regenerative & Developmental Biology at Tufts University are testing whether a replicated amniotic (womb fluid) environment can promote limb regeneration in adult mammals.

They’ve developed a small, cylindrical “regenerative sleeve” that can be filled with an aqueous solution and fastened onto the stump of a rat’s amputated limb. The sleeve is fitted with a variety of ports and electrical connections, so the researchers can… read more

World’s Largest Truck Goes Robotic

November 10, 2008

The largest truck in the world is about to become the largest robotic vehicle in the world. Computer scientists from Carnegie Mellon University have teamed up with engineers from Caterpillar to automate the 700-ton trucks, which are made to haul loads up to 240 tons from mines.

Princeton physicists connect string theory with established physics

May 3, 2007

Princeton researchers have found new mathematical evidence that some of string theory’s predictions mesh closely with those of a well-respected body of physics called “gauge theory,” which has been demonstrated to underlie the interactions among quarks and gluons.

The discovery could open up a host of uses for string theory in attacking practical physics problems.

Panel Sees No Unique Risk From Genetic Engineering

July 28, 2004

Genetically engineered crops do not pose health risks that cannot also arise from crops created by other techniques, including conventional breeding, the National Academy of Sciences said in a report issued yesterday.

The report suggests that in some cases, surveillance might be needed after a food gets to the market to check for possible health effects, something not done now. It also calls for some information on the composition… read more
