Body handles nanofiber better

December 18, 2003

Researchers from Purdue University have made a discovery that may hold promise for tissue regeneration: carbon nanofibers are surprisingly compatible with human tissue.

Their experiments showed that increasing the amount of carbon nanofibers in a polycarbonate urethane composite implant increased the functions of nerve and bone-forming cells and decreased the function of scar-tissue formation.

Carbon nanotubes also have strong electrical properties. “These carbon nanofibers also interact with neurons,… read more

Body Hacking slides from ETECH

April 3, 2007

Slides from a talk on “Body Hacking” at the O’Reilly Emerging Technology Conference 2007 last Thursday are now posted online.

“Quinn went well beyond modern primitivism and piercings and delved into the social mores of self-improvement through surgery and chemicals, the creation of new senses and new ‘super-powers.’”

A video of Quinn giving this talk in Berlin in December is available.

Body 2.0 — Continuous Monitoring Of The Human Body

March 23, 2009

Biomedicine, technology, and wireless communication are in the midst of a merger that will easily bring continuous, 24×7 monitoring of several crucial bodily functions in the years ahead.

Bodily maps of emotions

February 4, 2014

bodily maps featured

Researchers at Aalto University in Finland have compiled maps of emotional feelings associated with culturally universal bodily sensations, which could be at the core of emotional experience.

The researchers found that the most common emotions trigger strong bodily sensations, and the bodily maps of these sensations were topographically different for different emotions. The sensation patterns were, however, consistent across different West European and East Asian cultures, highlighting that emotions… read more

Blurring the distinction between a particle and its mirror image

April 6, 2011

Quantum Mirror

Physicists from Heidelberg Unversity, and colleagues from Technische Universität (München and Wein), have extended a thought experiment by Einstein and managed to blur the distinction between a particle and its mirror image by creating quantum superpositions.

The physicists experimentally produced motional coherence by a single spontaneous emission event close to a mirror surface. By placing atoms close to the mirror’s surface,… read more

Blurring the boundary between biology and machines, engineers create light-activated skeletal muscle for robots

Technique may enable robotic animals that move with the strength and flexibility of their living counterparts

Many robotic designs take nature as their muse: sticking to walls like geckos, swimming through water like tuna, sprinting across terrain like cheetahs. Such designs borrow properties from nature, using engineered materials and hardware to mimic animals’ behavior.

Scientists at MIT and the University of Pennsylvania have genetically engineered muscle cells to flex in response to light, and are using the light-sensitive tissue to build… read more

Bluetooth 3.0 Goes Live

April 23, 2009

The next-generation Bluetooth 3.0 will allow for a theoretical maximum throughput of 24 Mbps — enough to transmit HD videos.

Products are expected by yearend, but many current Bluetooth devices can be updated to Bluetooth 3.0 via driver, firmware, or software update.

Blueprints drawn up for quantum computer RAM

August 22, 2007

Scuola Normale Superiore researchers have proposed a method for retrieving quantum information from memory that should make total quantum recall more reliable.

Blueprint for a Quantum Electric Motor

September 18, 2009

Quantum-motor

Two atoms trapped in a ring-shaped optical lattice driven by an alternating magnetic field can create the smallest electric motor, University of Augsburg researchers have discovered.

IBM’s Blue Gene/L supercomputer continues its four-year domination of the official
TOP500 Supercomputer Sites list
for 2007, announced today.

The IBM supercomputer at Lawrence Livermore National Laboratory was expanded this summer to deliver a sustained performance of 478.2 teraflops, up from 280.6 teraflops in June.

The No. 2 computer in the world — and Europe’s fastest — is the new first-time installation of… read more

BlueGene/L doubles up

March 25, 2005

BlueGene/L, already number one on the latest Top 500, nearly doubled its performance — now at 135.3 teraflops — after doubling its processor count at Lawrence Livermore National Laboratory.

BlueBiped: A human-like walking robot that requires no power source

October 26, 2011

bluebiped-robot-legs-348x196

Robot legs propelled entirely by their own weight that can walk with a human-like gait without motors or external control have been developed by researchers at the Nagoya Institute of Technology in Japan, ExtremeTech reports.

The robot legs are basically just an imitation of human physiology, with thighs and lower legs made out of aluminum that are the same length as their human counterparts, and ankles and… read more

Blue Waters, one of the world’s most powerful computers, opens for research

April 2, 2013

Blue Waters has been configured to solve the most challenging compute-, memory- and data-intensive problems in science and engineering. It has tens of thousands of chips (CPUs & GPUs), more than a petabyte of memory, tens of petabytes of disk storage, and hundreds of petabytes of archival storage. (Credit: NCSA/University of Illinois)

Blue Waters, one of the most powerful supercomputers in the world, was formally declared available for use today at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign (UIUC).

Blue Waters, a partnership among NSF, the State of Illinois, the University of Illinois and the Great Lakes Consortium for Petascale Computation, is capable at peak performance of nearly  12 petaFLOPS (12… read more

Blue LEDs to reset tired truckers’ body clocks

March 19, 2008

Blue LEDs in truck cabs and truck stops could be the key to reducing accidents caused by drowsy drivers by convincing the brain it’s morning, say Rensselaer Polytechnic Institute researchers.

Nearly 30% of all fatal accidents involving large trucks in the US happen during the hours of darkness.

Blue implantable film delivers drugs at the flick of a switch

February 12, 2008

MIT scientists have developed a drug-infused film that breaks down when a voltage is applied across its surface, allowing it to be used as an implantable device that releases precise doses of a drug into a patient’s bloodstream.
