Using artificial intelligence techniques to forecast solar flares*, Stanford solar physicists have automated the analysis of the largest-ever set of solar observations, using data from the Solar Dynamics Observatory (SDO).

Solar physicists identify which features are most useful for predicting solar flares, which requires processing more data — some 1.5 terabytes a day — than any other satellite in NASA history, according to solar physicists… read more

Neurons fire like shotguns, not rifles

July 15, 2005

The synapse may behave more like a shotgun than a rifle when it comes to firing the neurotransmitters involved in neuronal communication, says a Howard Hughes Medical Institute research team led by investigator Terrence Sejnowski.

They created a detailed 3-D map of the synapse of a chick ciliary ganglion. The new 3-D modeling technique could offer a powerful tool for understanding neurological disease, such as myasthenia gravis, a common… read more

New health book, TRANSCEND, by Kurzweil and Grossman published

April 28, 2009

TRANSCEND: Nine Steps to Living Well Forever by Ray Kurzweil and Terry Grossman, MD, published April 28, presents an easy-to-follow, practical, nine-step program to dramatically slow down aging and disease processes “so that you can be in good health when we get dramatic new technologies that will enable us to essentially reprogram the outdated ‘software’ (our genes) that runs in our bodies,” said Kurzweil. “These new methods are only ten… read more

The Serious Search for an Anti-Aging Pill

July 25, 2002

A pill that mimics the life-prolonging effects of caloric restriction by inhibiting glucose metabolism could enable people to stay healthy longer, postponing age-related disorders — without requiring people to go hungry.

More ‘functional’ DNA in genome than previously thought

December 12, 2007

Johns Hopkins researchers have found that the computer programs used in current methods of scanning the genome for regulatory DNA, regions of DNA that can control gene activity, could miss more than 60% of these regulatory DNA sequences.

In their pilot project, Hopkins researchers conducted an exhaustive analysis of the DNA sequence around the phox2b gene in Zebrafish, and found 17 regulatory sequences. The team then analyzed the entire… read more

Life’s ingredients found in early universe

July 31, 2005

The molecular building blocks of life had already formed by the time the universe was only a quarter of its present age, new observations by NASA’s Spitzer Space Telescope reveal. The research bolsters the case for extraterrestrial life and may shed light on the nature of galaxies in the early universe.

The signature of polycyclic aromatic hydrocarbon (PAH) molecules were found in two galaxies. The molecules contain about 100… read more

Research gives clues for self-cleaning materials, water-striding robots

May 5, 2009

Self-cleaning walls, counter tops, fabrics, even micro-robots that can walk on water could be closer to reality because of research on super-hydrophobic materials by scientists at the University of Nebraska-Lincoln and at Japan’s RIKEN institute.

Using the supercomputer at RIKEN (the fastest in the world when the research started in 2005), the team designed a computer simulation to perform tens of thousands of experiments that studied how surfaces behaved… read more

The E-Gang: Medical Marvels

August 16, 2002

Forbes profiles eight visionaries in information technology for medicine.

  • Neuroscientist Kari Stefansson’s gene-mining software will allow doctors to create genetic profiles of patients within a decade.
  • TIGR’s Claire Fraser gene tests could one day let doctors customize drug treatment for the exact genetic strain found in their patients.
  • Rosetta Inpharmatics’ Stephen Friend plans to use DNA chips to spot which genes are most active in

    Scientists work toward engineered blood vessels

    December 18, 2007

    MIT scientists have found a way to induce cells to form parallel tube-like structures that could one day serve as tiny engineered blood vessels.

    The researchers found that they can control the cells’ development by growing them on a surface with nano-scale patterning. Engineered blood vessels could one day be transplanted into tissues such as the kidneys, liver, heart or any other organs that require large amounts of vascular… read more

    The State Of Surveillance

    August 9, 2005

    Research laboratories envision tools that could identify and track just about every person, anywhere — and sound alarms when the systems encounter hazardous objects or chemical compounds.

    Many such ideas seem to leap from the pages of science fiction: An artificial nose in doorways and corridors sniffs out faint traces of explosives on someone’s hair. Tiny sensors floating in reservoirs detect a deadly microbe and radio a warning. Smart… read more

    2 Billion Infected? WHO Stokes Swine Flu Fear

    May 8, 2009

    The World Health Organization may have inadvertently triggered a new wave of fear over the threat of a swine flu pandemic today by suggesting that up to 2 billion people could be infected if the current outbreak worsens.

    WHO chief Keiji Fukuda quickly noted to reporters that he was making statement based on data from past pandemics and was not a predicting what would happen with the current swine… read more

    Controlling movies with brainwaves

    Mind Wave

    MyndPlay, Ltd. is launching a new mind-controlled media platform is being launched at the Gadget Show Live in the UK this week.

    The company claims it is the first mind-controlled media player and content development system that connects with EEG brain-computer interface (BCI) technology to allow viewers to change the direction and outcome of a video or movie using only their minds. It connects with NeuroSky’s EEG… read more

    Kurzweil receives honorary doctorate at Landmark College

    September 6, 2002

    Dr. Ray Kurzweil received an honorary doctorate degree from Landmark College of Putney, Vermont today. Landmark College is the nation’s premier college for high-potential students with learning disabilities and attention deficit hyperactivity disorder. “Ray Kurzweil’s impact on students with learning disabilities has been immeasurable,” noted Landmark president Lynda J. Katz, Ph.D. “The extraordinary strides some of our students make at Landmark College would simply not be possible were it not… read more

    ‘Nanocavity’ Sensor Detects Virus-Sized Particles

    December 21, 2007
    Nanocavity sensor (Philippe Fauchet)

    University of Rochester scientists have created a nanoscale device capable of detecting one quadrillionth of a gram of biological matter, or about the size of certain viruses.

    In the future, the sensor may be able to detect influenza, severe acute respiratory syndrome (SARS), bird flu, and other viruses.

    The sensor is a hexagonal array of tiny cavities, each 240 nanometers in diameter, carved into a very… read more

    Watching Over You

    August 21, 2005

    The MDKeeper, from Tadiran Spectralink, provides round-the-clock medical monitoring for at-risk patients.

    It is worn like a watch and integrates various medical sensors, a Siemens GSM/GPRS radio module, and a built-in cellular speakerphone and processing unit to measure and transmit data to caregivers.

    The MDKeeper measures vital signs, including pulse rate, cardiac rhythm (ECG or EKG), and blood oxygen levels. It can either store the data and transmit… read more
