Human Brains May Take Unique Turn

September 4, 2001

Neuroscientists have tapped into what may represent a fundamental difference in brain development between people and other mammals and may offer insight into how humans evolved an enlarged frontal cortex capable of supporting symbolic thought and language use.In the new study, researchers injected a dye into the telencephalon of living tissue slices taken from the brains of 15-to-26-week-old human fetuses, as well as from monkey and mouse fetuses of comparable… read more

Hackers can manipulate outdated algorithms to give two very different documents the same digital signature.

3-D avatar to help doctors visualize patient records and improve care

October 3, 2007

IBM’s Zurich Research Lab has developed an avatar to allow doctors to visualize patient medical records.

The Anatomic and Symbolic Mapper Engine (ASME) allows a doctor to click on a particular part of the computer avatar “body” to trigger a search of medical records and instantly see all the available medical history and information related to that patient’s problem area, including text entries, lab results and medical… read more

Self-assembled nano-sized probes image tumors through flesh and skin

February 8, 2005

Nano-sized particles embedded with bright, light-emitting molecules have enabled researchers to visualize a tumor more than one centimeter below the skin surface using only near-infrared light.

They used fluorescent materials called porphyrins within the surface of a polymersome, a cell-like vesicle, to image a tumor within a living rodent. It should also be possible to use an emissive polymersome vesicle to transport therapeutics directly to a tumor.

‘Nanoscoops’ could dramatically improve batteries for electric vehicles and personal electronics

January 5, 2011

Nanoscoop (Rensselaer/Koratkar)

An entirely new type of nanomaterial developed at Rensselaer Polytechnic Institute could enable the next generation of high-power rechargeable lithium (Li)-ion batteries for electric automobiles, as well as batteries for laptop computers, mobile phones, and other portable devices.

The new material, dubbed a “nanoscoop” because its shape resembles a cone with a scoop of ice cream on top, can withstand extremely high rates of charge and discharge that would… read more

From the Past, Images of the Future

September 26, 2001

A sampling of visions of the future from the past has been published in “Visions of Spaceflight: Images From the Ordway Collection” by rocket scientist, space historian and author, Frederick I. Ordway.

Sexy View coming to phones near you

March 10, 2009

A worm named “Sexy View” can spread through malicious links in text messages. This creates a bridge between mobile phones and the Internet, which means mobile botnets controlled by cyber-criminals may not be far away.

The tiny addition of a chemical mark called called a methyl group atop a gene that is well known for its involvement in clinical depression and posttraumatic stress disorder can affect the way a person’s brain responds to threats, according to a new study by Duke University researchers.

The study results, published August 3 in Nature Neuroscience, go beyond genetics to help explain why some… read more

Cram 4TB on Desktop Drives by 2009, Hitachi Says

October 15, 2007

Hitachi Global Storage Technologies has developed technology that will quadruple the storage capacity of desktop hard drives within the next two years.

Desktop computers could attain a capacity of 4TB of storage while laptop storage could reach 1TB, according to Hitachi. Hard drives are currently doubling in capacity every two years, said John Best, chief technologist at Hitachi Global Storage Technologies.

A genius explains

February 22, 2005

Daniel Tammet is an autistic savant who can perform mind-boggling mathematical calculations at breakneck speeds.

He can also describe how he does it. Now scientists are asking whether his exceptional abilities are the key to unlock the secrets of autism.

The Search for a Clearer Voice

January 12, 2011

Google’s improved Voice Search takes speech recognition to its next level: Google’s servers will now log up to two years of your voice commands in order to more precisely parse exactly what you’re saying.

In tests on the new app, which appeared in Google’s Android Market a week before Christmas, the app originally got about three out of five searches correct. After a few days, the ratio crept up… read more

Unlocking the Paralysis Riddle

October 25, 2001

Researchers studying spinal cord injuries have observed certain patterns of the human brain that may ultimately enable paraplegics and quadriplegics to regain some motor activity in their paralyzed limbs — or use their brains to control robotic limbs.

Researchers took MRI snapshots of the brains of quadriplegics as they were asked to move their hands, elbows, feet, knees and lips. The images revealed neural activity in all the places… read more

Single-Molecule Magnets Open New Door for Information Technology

Recent research by scientists in Italy and France shows that that single molecules have the ability to store information via their magnetic state –a first step toward a new generation of ultra-compact data storage technologies based on individual molecules.

Micro-robot that can clear arteries

October 23, 2007

A microscopic robot small enough to travel through blood vessels has been built by scientists at Chonnam National University in Korea.

The robot walks like a crab on six legs and has been designed to clear blocked arteries. By attaching grafted heart muscle to the legs, the scientists found the legs would bend as the muscle cells contracted. The cells get their energy from sugar in the patient’s blood.… read more

Laughing helps arteries and boosts blood flow

March 8, 2005

Laughing appears to be almost as beneficial as a workout in boosting the health of blood vessels, a new study suggests.

Results of the study, based on ultrasound measurements of blood flow and dilation in the brachial artery in the arm, suggest that laughter could help keep the lining of the arteries healthy and thus reduce the risk of cardiovascular disease.
