Drugs to Grow Your Brain

Researchers at BrainCells Inc. have developed drugs that encourage the growth of new neurons (neurogenesis) in the brain.

The drugs could also treat depression without the side effects and failure rate of existing antidepressant medication.

Scientists have found that new neurons are born in the adult brain and that increases or decreases of neurons may be involved in many brain diseases, including depression, schizophrenia and stroke.

Single molecule makes electronic switch

A single organic molecule trapped between two electrodes acts as a switch and has a memory of the type used in data storage, researchers have found.

A positive voltage pulse between the electrodes was enough to change the bipyridyl-dinitro oligophenylene-ethynylene dithiol (BPDN-BT) molecule so that it became a better conductor of current, while a negative voltage returned the molecule to its less conductive state.

Smart Cards Track Commuters

October 8, 2003

Civil rights campaigners have expressed concerns about new smart travelcards that track a London commuter’s movements and store them in a database.

Holodeck 1.0? Star Trek-style 3-D displays make their debut

The EU-funded Coherent research project has developed a 3-D display called the HoloVizio.

The HoloVizio is a 3-D screen that will allow designers to visualize true 3-D models of objects, such as models for the medical sector and a collaborative design review system for the automotive industry. Users can manipulate the models by waving their hands in front of the screen.

The aim of the project… read more

Revealed: world’s oldest computer

August 22, 2006

The “Antikythera mechanism,” found amid the wreckage of a cargo ship that sunk off the tiny island of Antikythera in 80 BC, is the world’s oldest computer, used to map the motions of the sun, moon and planets.

Moms Battle Genetic Engineering

October 20, 2003

A group of New Zealand mothers led by a former pop star have launched a provocative billboard campaign to protest their government’s decision to allow agricultural genetic engineering.

The billboard ads feature a four-breasted woman attached to a milking machine.

China Details Homemade Supercomputer Plans

January 20, 2010

China’s next supercomputer, the petascale Dawning 6000, will be constructed exclusively with home-grown microprocessors, running by the end of 2010.

Researchers show how the brain can protect against cancer

June 10, 2008

Rutgers University scientists have shown that neurons that produce the beta-endorphin peptide (BEP) “feel good” hormone — released during exercise, a good conversation, and many other aspects of life that give humans pleasure — play a roles in regulating the stress response and immune functions to control tumor growth and progression.

To test their hypothesis about the role of BEP in controling tumor growth and progression, the Rutgers scientists… read more

Supercentenarian Research Foundation Plans Tissue Sampling of Supercentenarians

September 5, 2006

The Los Angeles Gerontology Research Group has created a tax-exempt Supercentenarian Research Foundation to fund tissue sampling of all living Supercentenarians (persons 110 years or older) worldwide.

The aim of the Foundation is “to develop a rigorous, statistically significant database of the most important SNPs (Single Nucleotide Polymorphisms) of ‘gerontic’ (longevity) genes,” said Los Angeles Gerontology Research Group Co-founder L. Stephen Coles, M.D., Ph.D.… read more

Man who lost bionic arm waits to be rebuilt

October 28, 2003

Advances in technology are making the fiction of the Bionic Man a reality.

One prototype developed by Edinburgh-based Touch EMAS is able to sense electrical currents from a person’s shoulder muscles. Microchips can then translate them into specific movements of its joints.

Scientists at Duke University said this month that brain implants allowing severely disabled people to control prosthetic limbs with their minds could be ready for use… read more

Innovation: Apple patents hint at tablet’s technology

January 26, 2010

A rash of patents filed by Apple suggests how the new Apple tablet may take the next step beyond the iPhone’s once-revolutionary touch interface.

Making Old Muscle Young

June 17, 2008

Researchers at University of California, Berkeley have manipulated stem cells in older muscle tissue to produce new muscle fibers at levels comparable to young stem cells.

Old muscle tissue produces elevated levels of the molecule TGF-beta, which is known to inhibit muscle growth. The researchers used RNA interference, which can silence specific genes, to inhibit the TGF-beta pathway in old mice.

Muscle wasting–loss of muscle mass–occurs both during… read more

Discovery allows for connecting nanotubes in circuits

September 19, 2006
Some molecular handles can transform between a bond-intact state (left), and a bond-broken state (right), allowing the nanotubes to act like switches that can be turned on or off in the presence of certain substances or with a laser beam.

MIT researchers have identified a class of chemical molecules that preserve the metallic properties of carbon nanotubes and their near-perfect ability to conduct electricity with little resistance.

Using these molecules as handles could overcome fabrication problems and lend the nanotubes new properties for a host of potential applications as detectors, sensors or components in novel optoelectronics.

Nanowire film brings cheaper, faster electronics a step closer

November 7, 2003

Researchers at Harvard University have demonstrated for the first time that they can easily apply a film of tiny, high-performance silicon nanowires to glass and plastic, a development that could pave the way for the next generation of cheaper, lighter and more powerful consumer electronics.

According to Dr. Charles M. Lieber, head of the research project and a professor of chemistry at Harvard, the first devices made with this… read more
