How the CNN Holographic Interview System Works

November 4, 2008
Also see: Election-night news to co-star latest technology

CNN’s “holographic” election coverage uses 35 HD cameras pointed at different angles at the remote subject in a ring. Computers in the CNN studio then merge the video feeds into a composite image that simulates a Star-Wars-style hologram.

Berkeley Lab researchers achieve nanoscale shape-memory effect

December 5, 2013

This AFM image shows a recoverable phase transformation in a bismuth ferrite film introduced by an applied electric field. The dashed blue line shows the relocation of the phase boundaries.

A research team at Berkeley Lab has discovered a way to introduce a recoverable strain into bismuth ferrite of up to 14 percent on the nanoscale, larger than any shape-memory effect observed in a metal. This discovery opens the door to applications in a wide range of fields, including medical, energy and electronics.

“Our bismuth ferrite not only displayed the champion shape-memory value, it was also far… read more

Will Bioterror Fears Spawn Science Censorship?

April 30, 2007

A draft of new rules adopted by the National Science Advisory Board for Biosecurity, or NSABB, proposes voluntary compliance by scientists, universities and journals to limit publication of life-sciences research that could be misused by terrorists.

It defines that as “research that, based on current understanding, can be reasonably anticipated to provide knowledge, products, or technologies that could be directly misapplied by others to pose a threat to public… read more

Verizon’s fiber race is on

July 20, 2004

Verizon Communications plans to debut a 30mbps broadband-over-fiber service called Fios to homes later this summer.

It will offer voice calls, video and broadband in competition with telephone and cable companies, initially in three cites.

A 2mbps to 5mbps Fios connection will cost $35 a month if purchased along with Verizon’s local and long-distance telephone service. A connection of up to 15mbps is available for $45 a month… read more

Invention: Cancer nanobomb

November 11, 2008

Balaji Panchapakesan at the University of Delaware suggests destroying cancers in situ using exploding nanotubes.

His idea is to fill carbon nanotubes with water before injecting them into a tumor. The area is then zapped with laser light, which causes the water inside the nanotubes to boil. The tremendous pressure created by the heating causes the “nanobombs” to burst apart, killing nearby cells.

Navy Heats Up Cold Fusion Hopes

May 6, 2007

Scientists at Navy’s Space and Naval Warfare Systems Center (Spawar) claim they have achieved a low energy nuclear reaction (LERN) in an experiment that can be replicated and tested.

They coated a thin wire with palladium and deuterium, then subjected it to magnetic and electric fields. The researchers have offered plastic films called CR-39 detectors as evidence that charged particles have emerging from their reaction experiments.

Homegrown labware made with 3D printer

April 17, 2012

Armed with a 3D printer and ordinary silicone-based sealant, University of Glasgow researchers have demonstrated a novel way to control chemical reactions: by making the reaction vessel an integral part of the experiment itself.

The results could open the door to a new generation of custom labware ( which they call “reactionware”) made to suit individual researchers’ needs.

University of Glasgow chemist Leroy Cronin envisions that in the distant… read more

August 2009: How Google beat Amazon and Ebay to the Semantic Web

August 2, 2004

You can see why Google was a natural to put it all together. Google already searched the entire Web. Google already had a distributed framework with thousands of independent machines. Google already looked for the links between pages, the way they fit together, in order to build its index. Google’s search engine solved equations with millions of variables. Semantic Web content, in RDF, was just another search problem, another set… read more

KurzweilAI newsletter publishing glitch

August 17, 2010

KurzweilAI experienced an unusual glitch in its newsletter publishing process Monday that made the newsletter received by some subscribers unreadable. The problem was caused by a timeout created by a temporary slow or bad Internet connection between two servers.

Monday’s news can be read in the KurzweilAI News section.

‘Invisible’ transplant organs now in sight

November 17, 2008

Organs that are invisible to our immune system, so they won’t be rejected when they are transplanted, could be ready within 10 years, thanks to a faster way of genetically engineering pigs developed by Hammersmith Hospital in London and California Institute of Technology researchers.

Get slim on the office treadmill

May 17, 2007

Mayo Clinic obesity experts have developed a vertical workstation that helps employees take exercise and lose up to 30kg a year weight as they work.

Biology Enters Fourth Dimension

August 13, 2004

A new microscope that lets scientists peer deeper into living organisms than ever before and in real time has been developed by researchers at the European Molecular Biology Laboratory.

The technology, called Selective Plane Illumination Microscopy, or SPIM, allows scientists to study relatively large (2 to 3 millimeter) live organisms from many different angles, under real conditions and with minimal disruption to the specimen.

SPIM shines a very… read more

Google Gives Real-Time Search Its Own Page

August 27, 2010

Google’s new real-time search page displays only results from timely sources, like updates from Twitter, Buzz, Facebook, Friendfeed, MySpace, Jaiku and

Google sorts real-time search results based on many elements, including how many followers the writer has, how often the subject is being written about and how many times people are reposting messages.

Plumbing the oceans could bring limitless clean energy

November 21, 2008

Ocean Thermal Energy Conversion (OTEC) — which exploits the difference in temperature between seawater near the surface and deep down — has the potential to become the biggest source of renewable energy in the world, says Robert Cohen, who headed the US federal ocean thermal energy program in the early 1970s.

Extending future electric-car battery life, range

A hybrid anode made of graphite and lithium could quadruple the lifespan of lithium-sulfur batteries (credit: Huang et al, Nature Communications)

A hybrid anode developed at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) could quadruple the life of the lithium-sulfur batteries proposed for use in electric vehicles.

“Lithium-sulfur batteries could one day help us take electric cars on longer drives and store renewable wind energy more cheaply, but some technical challenges have to be overcome first,” said PNNL Laboratory Fellow Jun Liu. “PNNL’s new anode… read more
