Using artificial intelligence to chart the universe

September 25, 2012

cosmic_web

Astronomers at the Leibniz Institute for Astrophysics have developed an AI algorithm to help them chart and explain the distribution of dark matter with unprecedented accuracy.

The algorithm starts with the fluctuations in the density of the universe seen in the cosmic microwave background radiation (CMBR), then models the way matter collapses into today’s galaxies over the subsequent 13 billion years. The results of the algorithm are… read more

Using carbon nanotubes as qubits for quantum computers

March 26, 2013

nano_guitar_tum

A study by physicists at the Technical University of Munich (TUM) has shown how nanotubes can store information in the form of vibrations.

Using quantum mechanical phenomena, computers could be much more powerful than their classical digital predecessors.

Up to now, researchers have experimented primarily with electrically charged particles. But because nanomechanical devices are not charged, they are much less sensitive to electrical interference.… read more

Using Carbon Nanotubes For Quantum Computing

July 16, 2004

Academics at the University of Oxford have developed a design protocol for inserting filled molecules of Buckminsterfullerene (“Buckyballs”) into carbon, and other types of nanotubes.

The Buckyballs are themselves filled with molecules that have either an electronic or structural property that can be used to represent a quantum bit (Qubit) of information and can be associated with other adjacent Qubits. The improved stability of the system now allows several… read more

Using carbon nanotubes to seek and destroy anthrax toxin and other harmful proteins

December 11, 2007

Rensselaer Polytechnic Institute researchers have developed a new way to seek out specific proteins, including dangerous proteins such as anthrax toxin, and render them harmless using nothing but light.

Ravi S. Kane, professor of chemical and biological engineering, described the research: “By attaching peptides to carbon nanotubes, we gave them the ability to selectively recognize a protein of interest — in this case anthrax toxin — from a mixture… read more

Using cells’ chemical signaling to control cancer or detect toxins

November 17, 2011

Cell signals

MIT researchers have found that cells’ chemical signaling mechanisms can tell whether their signals are being received, and then adjust the volume of their messages as needed.

Cells use these chemical signaling systems to control many basic functions. For example, signaling can control how genes are turned on and off in response to external or internal cues, how cells grow and organize their internal structures, and even… read more

Using DNA to Control Nanoparticle Assembly

August 22, 2007

Uing DNA, researchers at the U.S. Department of Energy’s Brookhaven National Laboratory are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters.

The synthetic DNA used in the laboratory is capped onto individual gold nanoparticles and customized to recognize and bind to complementary DNA located on other particles. This process forms clusters containing multiple particles.

The research could… read more

Chemical “nanoblasts” activated by bursts of laser light can punch tiny holes in the protective membranes of cells just long enough to admit therapeutic small molecules, proteins and DNA directly into living cells, Georgia Institute of Technology.researchers have discovered.

“One of the most significant uses for this technology could be for gene-based therapies, which offer great promise in medicine, but whose progress has been limited by the difficulty of getting… read more

In another Minority Report-like research finding, a UCLA research team has made crucial advances in “brain reading,” using fMRI and machine learning methods to predict reactions of smokers experiencing nicotine cravings.

The research, presented last week at the Neural Information Processing Systems Machine Learning and Interpretation in Neuroimaging workshop in Spain, was funded by the National Institute on Drug Abuse, which is interested in using… read more

Glucose meters can be used as simple, portable, inexpensive meters for a number of target molecules in blood, serum, water or food, researchers at the University of Illinois have found.

To use glucose meters to detect a target other than glucose, the researchers coupled them with a class of molecular sensors called functional DNA sensors. Functional DNA sensors use short segments of DNA that bind to specific… read more

A Queensland Institute of Medical Research (QIMR) Associate Professor David Harrich has developed a way to use HIV to beat HIV in the laboratory.

He has determined how to modify a protein in the virus, creating the the “Nullbasic” protein, which provides strong, lasting protection from infection by stopping the virus from replicating in a lab environment. Animal trials are due to start this year.

“If this… read more

Using Humans as a Computer Model

October 16, 2001
Automated switching allowed AT&T/Bell Labs to keep up with the demand for telephones

The computer industry’s “next grand challenge” is the ever-increasing complexity of computing in the Internet era, with its global networks and proliferation of digital devices, says Paul M. Horn, a senior vice president who oversees the research labs at I.B.M., in a paper, “Autonomic computing.”

“Autonomic computing” is a biological metaphor suggesting a systemic approach to attaining a higher level of automation in computing.… read more

Using Kinect gesture technology in the operating room

March 1, 2012

siemens_console_surgery

Researchers from Siemens Healthcare have adapted Microsoft’s Kinect gesture technology to allow surgeons to use hand and arm movements to change x-ray images and zoom in on details.

To convert surgeons’ precise hand movements into exact commands, Siemens programmers have developed algorithms that identify the surgeon’s hands and register their movements without becoming “confused” by the presence of other people in the room.

The Google research team has been working on some new approaches to large-scale machine learning, Google Official Blog reports.

Today’s machine learning technology takes significant work to adapt to new uses. For example, say we’re trying to build a system that can distinguish between pictures of cars and motorcycles.

In the standard machine learning approach, we first have to collect tens of thousands of pictures that have already been

UC Berkeley and College of New York researchers are using lasers to control the fundamental nuclear spin properties of semiconductor materials.

Today’s computers are reaching the limits of what simple miniaturization can achieve.

Their laser techniques promise to speed the creation of “spintronic” devices that use the spin state of electrons to control the memory and logic circuits in chips.

“We can use these laser techniques… read more

Using light to create a safer, more reliable pacemaker

September 26, 2011

Stanford University researchers have for the first time engineered human hearts to respond to light, in a breakthrough that could lead to biological rather than electrical pacemakers.

The pacemaker has served heart patients well over the years. Today, surgically implanted electrical pacemakers and defibrillators are commonplace, regulating the pulses of millions of faulty hearts around the globe. “But neither is without problems,” said Stanford research fellow… read more
