An initiative to determine the next scientific or technological breakthrough for humankind is being unveiled by the EU via the Future and Emerging Technologies (FET) program at the European Future Technologies Conference in Budapest.
Researchers are working to create replacement human tissue from a naturally occurring protein, elastin.
In animal studies financed by the Army, Dr. Kenton Gregory, director of the Oregon Medical Laser Center, has succeeded in patching what would usually be fatal wounds to the gastrointestinal tract and other organs with living tissue that is accepted by the body and that eventually becomes part of the organ itself.

The potential of carbon nanotubes to diagnose and treat brain tumors is being explored through a partnership between NASA’s Jet Propulsion Laboratory and City of Hope.
They plan to functionalize and attach inhibitory RNA to nanotubes and deliver it to specific areas of the brain. It could also be used to treat stroke, trauma, neurodegenerative disorders and other disease processes in the brain.
Diagnostic tools and sensors for bioscience and materials to enhance the fabrication of complex materials (such as gene chips) are the most likely nantechnology products to emerge in the next five years, according to experts.These will followed by diagnostic technologies to help researchers better understand and measure nanoscale interactions, mainly in biotech, then nanotherapeutic devices that will carry stores of drugs through the blood stream, and further off, nanoscale electronics.
The most massive quantum-mechanical superpositions of three different mass-energy states of “relic” neutrinos produced by the big bang may have slowed down, stretching them across the universe as it expanded, according to calculations by George Fuller and Chad Kishimoto of the University of California, San Diego.
A gene linked to type 2 diabetes and cholesterol levels is in fact a “master regulator” gene that controls the behavior of other genes found within fat in the body, researchers at King’s College London and the University of Oxford have found.
The researchers examined over 20,000 genes in subcutaneous fat biopsies from 800 UK female twin volunteers.
They found an association… read more
A special, free news feature in Science magazine explores 125 big questions that face scientific inquiry over the next quarter-century.
The questions include:
What Is the Universe Made Of?
What is the Biological Basis of Consciousness?
Why Do Humans Have So Few Genes?
To What Extent Are Genetic Variation and Personal Health Linked?
How Far Can We Push Chemical Self-Assembly?
What Are the… read more
Researchers at the J. Craig Venter Institute have crafted a bacterial genome from scratch, moving one step closer to creating entirely synthetic life forms–living cells designed and built by humans to carry out a diverse set of tasks ranging from manufacturing biofuels to sequestering carbon dioxide.
They pieced together the genes of Mycoplasma genitalium, the smallest free-living bacterium that can be grown in the laboratory.
The final step… read more
Nanotubes can be processed to acquire remarkable properties: fibers thinner than a human hair that can be woven as a cloth or into a 100-times stronger muscle, molecular-scale electronic circuits, low-cost TV displays, X-ray sources, heat sinks, and microscopic gears.
By spotting 85 percent of polyps, CT scans offer a way to detect the precancerous growths in a way that is less invasive than a conventional colonoscopy, a European team of researchers reports.
Human bone has a form of ‘glue’ or adhesive that acts as a shock absorber to help bone during stress, University of California Santa Barbara researchers have announced.
This “molecular shock absorber,” studied at a nano-scale molecular level using an atomic force microscope, is similar to that discovered in abalone shell. The discovery of these molecules may lead to better treatment of bone diseases. As Dr. Daniel Morse explains,… read more
Northwestern University and Brookhaven National Laboratory researchers have demonstrated a way to program strands of DNA to assemble nanoparticles into 3D structures, using squid-like gold nanoparticles with “arms” made of DNA.
The discovery points towards a new way to engineer materials from the bottom up. Previously, only flat shapes have been assembled in this way.
It included leading scientists commenting on various “universes”: physicist Seth Lloyd (the computational universe), physicist Paul Steinhardt (the cyclic universe), physicist Alan Guth (the inflationary universe), computer scientist Marvin Minsky (the emotional universe), and technologist Ray Kurzweil (the intelligent universe).

Optogenetics combines genetic engineering, lasers, neurology and surgery to create a mechanism for easier and more effective direct control of groups of neurons in treating disorders such as Parkinson’s, chronic pain, and depression.
The sensor is capable of detecting biological processes at a molecular level, such as the regulation of chemicals in and out of the cell. This can be used in the development of new drugs… read more
