Self-assembly could simplify nanotech construction

June 8, 2007

“Molecular origami” could become the latest nanotech construction technique, thanks to a Harvard University study.

The self-assembly process might yield simpler ways to make the microscopic components required by the electronics and computing industries.

Global to Local: The Social Future as seen by six SF Writers

Cory Doctorow, Pat Murphy, Kim Stanley Robinson, Norman Spinrad, Bruce Sterling and Ken Wharton discuss the quality of life in the future.

Spin soliton could make cell phone communication more secure

September 16, 2010

Soliton (NIST)

Researchers at the National Institute of Standards and Technology (NIST) have found theoretical evidence of a new way to generate the microwave transmissions used in modern communication devices such as cell phones. Their analysis, if supported by experimental evidence, could contribute to a new generation of wireless technology that would be more secure and resistant to interference than conventional devices.

The team’s findings point toward an oscillator that would… read more

Mumbai Terrorists Relied on New Technology for Attacks

December 9, 2008

The terrorists who struck Mumbai last month stunned authorities not only with their use of sophisticated weaponry but also with their comfort with modern technology, including GPS systems, satellite phones, and Internet VoIP phones.

Atom trap is a step towards a quantum computer

June 18, 2007

A device that can hold hundreds of atoms in a 3D array, and image each one individually, may be an important stepping stone towards developing a quantum computer.

‘Dolphin speaker’ to enhance study of dolphin vocalizations and acoustics

May 14, 2012


To gain new insights into how dolphins communicate, researchers at Tokyo University of Marine Science and Technology and  Fusion Inc. created a prototype of an extremely broadband “dolphin speaker” capable of projecting dolphins’ communication sounds, whistles, burst-pulse sounds, as well as detection sounds such as echolocation clicks.

Dolphins rely on the combination of a variety of vocalizations and vastly better acoustic abilities than humans to communicate with each other… read more

Brain’s ‘Storehouse’ for Memory Molecules Identified

September 27, 2004

Researchers at Duke University Medical Center and Brown University have pinpointed the molecular storehouse that supplies the neurotransmitter receptor proteins used for learning-related changes in the brain.

Their finding constitutes an important step toward understanding the machinery by which neurons alter their connections to establish preferred signaling pathways in the process of laying down new memories. Understanding such machinery could also offer clues to how it might degenerate in… read more

Semantic Sense for the Desktop

December 17, 2008

A European endeavor called the Nepomuk Project plans to introduce the Semantic Web to computers in the form of a “semantic desktop.”

The software generates semantic information by using “crawlers” to go through a computer and annotate as many files as possible. These crawlers look through a user’s address book, for example, and search for files related to the people found in there. Nepomuk can then connect a file… read more

A Technology Review reporter enters the new world of neuroenhancers by having his brain zapped with electricity and dosed with chemicals.

Mapping damaged connections in Phineas Gage’s brain

May 18, 2012

(Credit: )

In 1848, Phineas Gage, the supervisor for the Rutland and Burlington Railroad in Vermont was using a 13-pound, 3-foot-7-inch rod to pack blasting powder into a rock when he triggered an explosion that drove the rod through his left cheek and out of the top of his head.

Miraculously, Gage lived, becoming the most famous case in the history of neuroscience because of the injury’s reported effects on his personality… read more

Cancer Nanotechnology Research Center Funded

October 8, 2004

The NIH has awarded two universities grants totaling nearly $10 million to establish a multidisciplinary research program in cancer nanotechnology and develop a new class of nanoparticles for molecular and cellular imaging.

One grant will establish a multidisciplinary Bioengineering Research Partnership for scientists from Emory University and the Georgia Institute of Technology. The other grant will be used to develop advanced nanoparticle quantum dot probes for molecular and cellular… read more

New nanoparticles could improve cancer treatment

October 5, 2010

Drug-carrying nanoparticles designed by MIT and MGH researchers are decorated with tags that bind to molecules found on the surface of tumor cells. (MIT/MGH)

Researchers at MIT and Brigham and Women’s Hospital have developed a nanoparticle that can deliver precise doses of two or more drugs to prostate cancer cells.

In a study appearing online this week in the Proceedings of the National Academy of Sciences, the researchers tailored their particles to deliver cisplatin and docetaxel, two drugs commonly used to treat many different types of cancer.

Such particles could improve the… read more

A year in the quantum world

December 26, 2008

Four radical routes to a theory of everything, The great antimatter mystery, Anyons: the breakthrough quantum computing needs?, and Matter is merely vacuum fluctuations are among the year’s top 10 in-depth articles about the quantum world.

Scientists Create Breakthrough Sensor Capable of Detecting Individual Molecules

July 9, 2007

Applied physicists at the California Institute of Technology have figured out a way to detect single biological molecules with a microscopic optical device.

The method has already proven effective for detecting the signaling proteins called cytokines that indicate the function of the immune system, and it could be used in numerous medical applications, such as the extremely early detection of cancer and other diseases, as well as in basic… read more

‘Energy Blocker’ Kills Big Tumors in Rats

October 20, 2004

Johns Hopkins researchers have discovered that an apparently nontoxic cellular “energy blocker” can eradicate large liver tumors grown in rats.

The chemical, 3-bromopyruvate, blocks cancer cells’ conversion of sugar into usable energy, a process necessary to fuel the cells’ functions and growth, but appears so far to have little or no effect on normal tissues. Clinical trials are not likely for several years.
