Alzheimer’s researchers creating ‘designer tracker’ to quantify elusive brain protein, provide earlier diagnosis

April 26, 2013

Dual channel fluoresecence microscopy of Alzheimer’s disease brain reveals presence of extracellular Abeta- (red) and intracellular tau- (green) bearing lesions.  Figure courtesy of Kristen E Funk, PhD.

By using computer-aided drug discovery, an Ohio State University molecular biochemist and molecular imaging chemist are collaborating to create an imaging chemical that attaches predominantly to tau-bearing lesions in living brain.

Their hope is that the “designer” tracer will open the door for earlier diagnosis — and better treatments for Alzheimer’s, frontal temporal dementia and traumatic brain injuries like those suffered by professional athletes, all… read more

Japanese Store Selling Custom-Made Robots That Look Like Their Owners

December 15, 2009

Japanese department store Sogo & Seibu plans to offer robots that are custom-made to look just like their owners.

They will be life-size humanoids that can dpeak with a real person’s (recorded) voice.

IBM announces data storage breakthrough

May 16, 2006

Researchers at IBM say a new
method for cramming 6.67 billion bits into a square inch of tape and 8 terabytes on a single cartridge.

They contend that would be 15 to 20 times denser than today’s industry-standard tape products.

For a Sharp Brain, Stimulation

May 15, 2008

Researchers are more optimistic than ever about the potential of the aging brain, because recent evidence has challenged long-held beliefs by demonstrating that the brain can grow new nerve cells.

Regular physical activity may improve brain function, both by increasing blood flow to the brain and stimulating the production of hormones and nerve growth factors involved in neurogenesis. Animal studies have found that physically active animals have better memories… read more

Why We Die, Why We Live: A New Theory on Aging

July 21, 2003

A new theory of aging based on parental care explains why mortality is high among infants but rapidly drops: mutations that cause death late in childhood, when much has been invested, are removed more quickly from a population than are mutations that cause death in infancy. The theory can also explain the reduction of mortality after menopause: women care for children and contribute to their survival.

Unique nanomechanical response of DNA allows high-speed direct digital detection

December 22, 2009

A new type of nanoscale sensor feels the stiffness of DNA molecules on a microarray to distinguish the ones that formed the double helix with digital precision. The new technology dramatically improves and simplifies microarray analysis. (Sahin Group, Rowland Institute at Harvard)

Researchers at Harvard and Stanford University have reported a new technique for genetic analysis using nanomechanical response of hybridized DNA/RNA molecules.*

A new type of nanoscale sensor feels the stiffness of DNA molecules on a microarray to distinguish the ones that formed the double helix, with digital precision.

This technique is several orders of magnitude more sensitive than other approaches (such as fluorescent labels) and could allow for… read more

Caught up in the ‘Net

May 30, 2006

“Singularity,” the fusion of human, machine and the communication capacity of the web, may enable a spectacular and fundamental shift in our understanding of human consciousness.

“I am still a big believer in Artificial Intelligence; new software ‘shells’ that surround us as individuals and becomes our interface with the outside world,” says Diamandi. “The Internet will merge into these software shells, serving as a global nervous system interconnecting people… read more

Self-repairing aircraft could revolutionize aviation safety

May 20, 2008

A new technique, developed by Bristol University aerospace engineers, that mimics healing processes found in nature could enable damaged aircraft to mend themselves automatically, even during a flight.

If a tiny hole/crack appears in the aircraft (e.g. due to wear and tear, fatigue, a stone striking the plane etc), epoxy resin would “bleed” from embedded vessels near the hole/crack and quickly seal it up, restoring structural integrity. By mixing… read more

Nanotechnology: sink or swim?

July 28, 2003

In a report published today, a team at the University of Sheffield investigates the scientific reality behind nanotechnology and the current controversy about its risks and rewards.

How Calorie-Restricted Diets Fight Obesity and Extend Life Span

December 29, 2009

European scientists have identified changes in the levels of 6 proteins, including proteins that tell the body to store fat, that could serve as important markers for improving or tracking the effectiveness of therapies involving calorie-restricted diets.

New material can enhance energy, computer, lighting technologies

November 17, 2011

The image, called a “ball-and-stick modal,” illustrates the crystal structure of the new erbium crystal compound developed at ASU’s Nanophotonics Lab. The four different colors represent the four elements that were combined to produce the new material (credit: ASU)

Arizona State University researchers have created a new crystal nanowire material that promises advances in a range of scientific and technological pursuits.

ASU electrical engineering professor Cun-Zheng Ning  says the material, called erbium chloride silicate, can be used to develop the next generations of computers, improve the capabilities of the Internet, increase the efficiency of silicon-based photovoltaic cells to convert sunlight into electrical energy, and… read more

Congressman concerned about superintelligence becoming self-aware

June 9, 2006

Rep. Brad Sherman (D-Calif.) said at a House Science Committe meeting Wednesday that based on the opinions of experts, there is reason to believe that in about 25 years a supercomputer will be built that “exceeds human intelligence,” Inside Higher Ed reports.

Sherman said he hopes that some of the future researchers that the bills would cultivate will be steered toward the potentially emerging field of making… read more

Cell ‘organs’ get plastic upgrades

May 26, 2008

University of Basel researchers have built artificial polymer organelles (internal compartments in cells that carry out specialized metabolic functions) and added them to live human cells in a lab dish.

The 200-nanometers-wide capsule contained enzymes, just like natural organelles. The artificial organelle’s membrane can be chemically tuned to control which chemicals can pass through it and regulate the reactions inside.

Applications of an artificial organelle could include boosting… read more

Molecules build a bridge to spintronics

August 5, 2003

A new generation of devices that harness the spin of electrons has moved closer. In a recent experiment, University of California at Santa Barbara researchers have transferred electron spins across molecular “bridges” between quantum dots for the first time and at room temperature.

New year, new vitamin C discovery: It ‘cures’ mice with accelerated aging disease

January 5, 2010

A team of Canadian scientists have found that vitamin C stops and even reverses accelerated aging in a mouse model of Werner’s syndrome, but the discovery may also be applicable to other age-related diseases,.
