Seeing terror risk, US asks journals to cut flu study facts

December 21, 2011

A(H5N1) virus

For the first time ever, a government advisory board is asking scientific journals not to publish details of certain biomedical experiments, for fear that the information could be used by terrorists to create deadly viruses and touch off epidemics.

In the experiments, conducted in the United States and the Netherlands, scientists created a highly transmissible form of a deadly flu virus that does not normally spread from person to… read more

Seeing the S-curve in everything

July 21, 2011

S curve (credit: Wikipedia)

The ubiquitous logistics S-curve (also known as the sigmoid function) has long been recognized by economists and scientists. Now professor Adrian Bejan at Duke University, with collaborator Sylvie Lorente from the University Toulouse, has developed a theory that explains the reason for the prevalence of this particular pattern throughout nature and the man-made world.

Economic trends, population growth, the spread of cancer, or the adoption of new… read more

Seeing the songs of whales

February 1, 2010


Mark Fischer, an expert in marine acoustics, has come up with a new method of artistic representation of whale and dolphin vocalizations, using wavelet transforms.

Seeing the world with new eyes: Biosynthetic corneas restore vision in humans

August 26, 2010

A new study from researchers in Canada and Sweden has shown that biosynthetic corneas can help regenerate and repair damaged eye tissue and improve vision in humans.

They initiated a clinical trial in 10 Swedish patients with advanced keratoconus or central corneal scarring. Each patient underwent surgery on one eye to remove damaged corneal tissue and replace it with the biosynthetic cornea, made from synthetically cross-linked recombinant human collagen.… read more

Seeing through walls in real time

October 20, 2011

SAR Imagery

MIT Lincoln Laboratory researchers have developed a new radar system that looks through walls. This ultrawideband (UWB) phased-array sensor has real-time acquisition and processing capability and provides video-like synthetic aperture radar (SAR) images of people moving behind an 8-inch-thick cinder block or concrete wall.

The system demonstrated the ability to capture meaningful imagery at a 10.8 Hz frame rate through 4-inch- and 8-inch-thick, as well as… read more

Seeing Without Looking: Brain Structure Crucial for Moving the Mind’s Spotlight

December 29, 2009

The superior colliculus, a brain structure in the midbrain known for its role in the control of eye and head movements, is crucial for moving the mind’s attention, Salk Institute for Biological Studies researchers have found.

The research adds new insight into our understanding of how attention is controlled by the brain. The results are closely related to a neurological disorder known as the neglect syndrome, and they may… read more

Seeing-Eye Computer Guides Blind

March 31, 2004

Researchers are developing a computerized “seeing” assistant called called Tyflos that will help blind people read books, access Web pages, recognize faces and navigate unfamiliar rooms.

Tyflos consists of a tiny camera mounted on a pair of glasses, laptop carried in a backpack, headset and microphone. The laptop process the images and converts them into verbal messages conveyed to the user.

A parallel development, the iCare-Reader, enables blind… read more

The brain’s “seeking system” is hard-wired to obsessively love Google, Twitter, e-mail, and other electronic communication devices, fueled by the opioid neurotransmitter dopamine, according to neuroscientists.

Seeking answers from the cosmic consciousness

July 9, 2006

Stephen Hawking has turned to Yahoo Answers for public answers to the question: “In a world that is in chaos politically, socially and environmentally, how can the human race sustain another 100 years?”

By afternoon July 7, nearly 17,000 Yahoo users had responded.

SeeReal Hi-Res Holographic Display

June 18, 2007

SeeReal has demonstrated a prototype of a new holographic display.

It uses a 20 inch display that displays a real high-resolution 3D image apparently in front the screen. To overcome the need for the enormous data required to display high resolution 3D images, it creates a 30×30 pixel array for each of the 3D scene points and uses an eye tracker to know where your eyes are located, to… read more

Seesmic Desktop delivers seamless Facebook integration

Mac/PC twitterers: Seesmic Desktop version 0.2 has launched (a preview but solid), finally integrating Facebook and Twitter updates.

Seesmic is now the official Twitter/Facebook desktop app at @KurzweilAINews. Awesome. – Ed.

Segway creator unveils his next act

February 20, 2006

Dean Kamen, the engineer who invented the Segway, has invented two devices, each about the size of a washing machine, that can provide much-needed power and clean water in rural villages.

The water purifier makes 1,000 liters of clean water a day from any water source. The power generator makes a kilowatt off of anything that burns.

Segway robot opens doors

November 20, 2003

MIT researchers have crossed a robotic arm with the bottom half of a Segway to make a robot that can traverse hallways and open doors.

The researchers are aiming to give the robot the abilities to recognize whether it’s in a room or hallway, recognize and manipulate objects, take instructions, and learn.

Selective brain damage modulates human spirituality

February 11, 2010

Selective damage to the left and right posterior parietal regions induced a specific increase in a personality trait called self-transcendence (ST), thought to reflect a decreased sense of self and an ability to identify one’s self as an integral part of the universe as a whole, Dr. Cosimo Urgesi from the University of Udine and colleages have found by studying patients before and after surgery to remove a brain tumor.… read more

Selective coatings create biological sensors from carbon nanotubes

December 13, 2004

University of Illinois at Urbana-Champaign researchers have developed protein-encapsulated single-walled carbon nanotubes that alter their fluorescence in the presence of specific biomolecules.

The technique could generate many new types of implantable biological sensors. The researchers have already built a near-infrared nanoscale sensor that detects glucose.
