Time-lapse auroras over Norway

April 6, 2011


One of the largest auroral displays in recent years has appeared at the border between Norway and Russia, shown in this time-lapse animation near Kirkenes, Norway by Terje Sørgjerd in March 2011.

Aurora are often green when high energy particles strike the Earth’s atmosphere, causing the air to glow as electrons recombine with oxygen. Other colors are occasionally noticeable when atmospheric nitrogen is affected.

Heart may be home to its own stem cells

May 30, 2006

New York Medical College researchers have discovered the “home” of stem cells in the heart, lending credence to the idea that the heart has the capacity to repair itself. The finding raises the possibility that these cardiac stem cells could one day be manipulated to rebuild tissues damaged by heart disease.

Neuronal circuits able to rewire on the fly to sharpen senses

December 17, 2007

Researchers have for the first time described a mechanism called “dynamic connectivity,” in which neuronal circuits are rewired “on the fly” allowing stimuli to be more keenly sensed.

This new, biologically inspired algorithm for analyzing the brain at work allows scientists to explain why when we notice a scent, the brain can quickly sort through input and determine exactly what that smell is.

Music instruction aids verbal memory

July 28, 2003

Children with music training have significantly better verbal memory, according to a study published in the July issue of Neuropsychology.

The authors, psychologists at the Chinese University of Hong Kong, propose that music training during childhood is a kind of sensory stimulation that “somehow contributes to … better development of the left temporal lobe in musicians, which in turn facilitates cognitive processing mediated by that specific brain area, that… read more

Star Trek’s Warp Drive: Not Impossible

May 7, 2009

The faster-than-light warp drive, one of Star Trek’s hallmark inventions, is not strictly impossible, according to some researchers.

“The idea is that you take a chunk of space-time and move it,” said Marc Millis, former head of NASA’s Breakthrough Propulsion Physics Project.

Be careful with this brave new world

June 8, 2006

Where do we draw the line between eradicating genetic disease and enhancing a child?

In his new book, After Dolly: The Uses and Misuses of Human Cloning, Ian Wilmut considers the moral and ethical implications that the cloning of Dolly the sheep raises for mankind.

Spy planes to recharge by clinging to power lines

December 20, 2007

The US Air Force Research Lab is developing an electric motor-powered micro air vehicle that can “harvest” energy when needed by attaching itself to a power line, even temporarily changing its shape to look more like innocuous piece of trash hanging from the cable.

Much of the “morphing” technology to perform this has already been developed by DARPA, the Pentagon’s research division. Technologies developed in that program include carbon… read more

A Business Out of Thin Air

August 4, 2003

HoloTouch has developed technology that allows users to operate equipment simply by passing a finger through a holographic image.

The system uses lasers and infrared sensors to create images that can be manipulated in the air.

How RNA got started

May 14, 2009

Scientists may have figured out the chemistry that sparked the beginning of life on Earth. A series of simple, efficient chemical reactions that could have formed molecules of RNA from the basic materials available more than 3.85 billion years ago has been identified by University of Manchester scientists.

Artificial Intelligence Turns 50

Mapping Professional Networks

December 28, 2007

With its Lotus Connections and Atlas software, IBM is exploring how different visualizations of the social graph could be useful within businesses, as a way of helping people work more efficiently and make better connections.

Electronic ‘Etch A Sketch’ may boost quantum design

August 15, 2003

Erasable electrostatic lithography (EEL), uses an atomic force microscope to draw, modify, or erase a circuit by depositing spots of charge directly on to the surface of a semiconductor. It could significantly speed the design of quantum electronic devices.

Novel nanotechnology method to stimulate growth of new neurons in adult brain

May 21, 2009

Integrative FGFR1 Signaling (INFS), a new mechanism that plays a central role in adult brain stem cell development and prompts brain stem cells to differentiate into neurons, has been identified by University at Buffalo researchers.

The INFS mechanism is considered capable of repopulating degenerated brain areas, raising possibilities for new treatments for Parkinson’s disease, Alzheimer’s disease and other neurodegenerative disorders, and may be a promising anti-cancer therapy.

How bacteria could generate radio waves

April 25, 2011

Radio-frequency emissions from certain bacteria could be generated by free electrons moving around DNA loops as they transition between quantum energy levels, researchers at Northeastern University and University of Perugia suggest, based on modeling.

The frequencies would be at 0.5, 1 and 1.5 kilohertz, which are the frequencies that have been measured in E Coli bacteria by Luc Montagnier, who won the Nobel Prize for medicine in 2008. They… read more

Killer tomatoes attack human diseases

June 30, 2006

Genetically modified tomatoes containing edible vaccine are to be used to challenge two of the world’s most lethal viruses, HIV and the hepatitis B virus, by manufacturing proteins to prompt the body to create antibodies against the viruses.
