Nanotubes strengthen artificial muscles

July 16, 2007

Engineers at the Rensselaer Polytechnic Institute say carbon nanotubes could toughen up artificial muscles, based on the discovery that groups of nanotubes keep bouncing back after being compressed repeatedly.

Copper Circuits Help Brain Function; Could Tweaking the Circuits Make Us Smarter?

September 26, 2006

The flow of copper in the brain has a previously unrecognized role in cell death, learning and memory, according to research at Washington University School of Medicine.

The researchers’ findings suggest that copper and its transporter, a protein called Atp7a, are vital to human thinking. They speculate that variations in the genes coding for Atp7a, as well as other proteins of copper homeostasis, could partially account for differences in… read more

Tom Hanks and 3D TVs at the Consumer Electronics Show

January 9, 2009

Highlights from the opening day, Thursday, of the Consumer Electronics Show included:

  • HDTVs are getting thinner and bigger.
  • This is the year of 3D, with all of the same TV manufacturers showing off a variety of displays that work with either glasses, or create a 3D-like effect automatically on screen.
  • Palm gave the public a first look at the Pre, with a touchscreen like

    Motion, Sensitive

    November 29, 2010

    The line between the real and the virtual in video games is beginning to fade.

    Music games like Power Gig and Rock Band 3 are beginning to incorporate real musical instruments. Microsoft’s new Kinect system sees you and listens to you in your living room, letting you jump, swing, kick, or just sit on your couch and speak aloud to control what happens on your television. Meanwhile Internet games like Eve Online… read more

    How Does the Brain Work?

    November 11, 2003

    While lacking a coherent framework, scientists are making progress in mapping the correlations between brain activity and behavior.

    New imaging tools reveal circuits and overall patterns of activity as people solve problems or reflect on their feelings. Genes expressed in mouse brain cells are being mapped so that researchers can begin to find out if neurons that look alike have different proteins and functions. A magnetic device can knock… read more

    Soft Drinks Linked To Heart Disease Via Metabolic Syndrome

    July 25, 2007

    In a new study, the large-scale ongoing Framingham Heart Study has found that drinking more than one soft drink a day, whether regular or diet, may be linked to an increased risk of developing heart disease, via an increase in metabolic syndrome.

    Metabolic syndrome is a group of symptoms such as excess waist circumference, high blood pressure, elevated triglycerides, low levels of high-density lipoprotein (HDL or “good” cholesterol) and… read more

    South Korean researchers are reporting a significant development in making stretchable thin electrodes out of graphene, which could allow for “smart” clothing and large foldable displays that make reading news online more like reading it in print.

    New Visualization Tool Gives Real-Time View of What Scientists Are Reading

    December 8, 2010

    The scientific publisher Springer has launched a free analytics tool that gives you a peek into how people are using the publisher’s online content.

    The tool provides a number of interactive visualizations based on real-time data aggregated from Springer’s online offerings, including a map showing where the downloads are coming from, a constantly updated keyword tag cloud, and a graphical and textual display of real-time… read more

    Nano-transistor self-assembles using biology

    November 21, 2003

    A functional electronic nano-device has been manufactured using biological self-assembly for the first time. It harnesses the construction capabilities of DNA and the electronic properties of carbon nanotubes to create a self-assembling nano-transistor.

    The team used proteins to allow carbon nanotubes to bind to specific sites on strands of DNA. They then turned the remainder of the DNA molecule into a conducting wire. The team has already connected two… read more

    Bubble 2.0 Coming Soon

    August 2, 2007

    “Every single person working in the media today who experienced the dot-com bubble in 1999 to 2000 believes that we are going through the exact same process and can expect the exact same results–a bust,” says curmudgeon columnist John Dvorak.

    “It’s deja vu all over again. And since this moment in time is only the beginning of the cycle, the best nuttiness has yet to emerge.”

    Listening to the sound of skin cancer

    October 18, 2006

    Researchers at the University of Missouri-Columbia can now detect the spread of skin cancer cells through the blood by literally listening to their sound.

    The minimally invasive technique causes melanoma cells to emit ultrasonic noise, and could let oncologists spot early signs of metastases — as few as 10 cancer cells in a blood sample — before they even settle in other organs.

    The team’s method, called photoacoustic… read more

    A Tool to Verify Digital Records, Even as Technology Shifts

    January 27, 2009

    University of Washington scientists have developed the initial component of a public system for digitally preserving and authenticating first-hand accounts of war crimes, atrocities and genocide.

    The solution is a publicly available digital fingerprint, known as a cryptographic hash mark, that will make it possible for anyone to determine that the documents are authentic and have not been tampered with.

    At the heart of the system is an… read more

    Materials research courts biotechnology

    December 3, 2003

    Biomaterials presentations are peppering the weeklong series of research reports at the annual Materials Research Society meeting held in Boston. Since MRS is involved in virtually every area of modern industry and technology, its shift in emphasis from inorganic to organic and biological processes may suggest a trend for society as a whole.
