Zeno Could Be Next Robot Boy Wonder

September 6, 2007

Hanson Robotics’ latest creation is a 17-inch, 4.5-pound personal robot boy that can walk, talk, express emotions, and make eye contact.

The prototype, which will have a formal unveiling at Wired Nextfest in California next week, is described as an intelligent “conversational robot” and will ultimately be part of Hanson’s “Robokind” line of personal, interactive bots.

Zen training speeds the mind’s return after distraction, brain scans reveal

September 4, 2008

Experienced Zen meditators can clear their minds of distractions (being interrupted by a word-recognition task) more quickly than novices, according to a new brain imaging study by Emory University School of Medicine researchers.

“This suggests that the regular practice of meditation may enhance the capacity to limit the influence of distracting thoughts. This skill could be important in conditions such as attention deficit and hyperactivity disorder, obsessive-compulsive disorder, anxiety… read more

Zapping sleepers’ brains boosts memory

November 7, 2006

Applying a gentle electric current to the brain during sleep can significantly boost memory, University of Luebeck researchers report.

They believe this is due to the pattern of the applied current mimicking that seen in naturally occurring deep sleep, where memory consolidation is thought to take place.

Zapping Individual Cancer Cells

July 9, 2008

Engineers at the University of Texas at Austin have patented a laser microscalpel that allows a surgeon to operate on tissue one cell at a time, precisely targeting disease while leaving healthy surrounding cells alive.

The device combines two technologies–a femtosecond laser and two-photon fluorescence microscopy–into a single miniaturized, flexible probe. The probe can target single cells in three-dimensional space, penetrating up to 250 micrometers into tissue.

Zapping cancer cells with magnets

October 10, 2012


Magnetic nanoparticles can be used to kill cancer cells by controlling cell signaling pathways, researchers from Yonsei University in South Korea have demonstrated.

They developed magnetic nanoparticles that turn on apoptosis cell signaling (commands to kill cells) in cancer cells by using a remote, non-invasive magnetic field.

The magnetic switch uses zinc-doped iron oxide magnetic nanoparticles (Zn0.4Fe2.6O4), combined with a targeting antibody for death receptor 4 (DR4, a… read more

Zapping asteroids and space debris with a swarm of satellites firing lasers

March 28, 2012


No, it’s not a new version of the classic Asteroids video game. Engineers at the University of Strathclyde in Glasgow have envisioned a swarm of small agile satellites flying in formation, firing solar-powered lasers at an asteroid.

According to Dr. Massimiliano Vasile, of Strathclyde’s Department of Mechanical and Aerospace Engineering, the concept is more feasible than a single large spacecraft carrying a multi-mega watt laser.

“Our system is… read more

You’re far less in control of your brain than you think

When your eyes tell your hands what to think
October 1, 2012


You’ve probably never given much thought to the fact that picking up your cup of morning coffee presents your brain with a set of complex decisions. You need to decide how to aim your hand, grasp the handle and raise the cup to your mouth, all without spilling the contents on your lap.

A new Northwestern University study shows that, not only does your brain… read more

You’ve Had a Genetic Test. Now What?

June 13, 2008

A new project by Coriell Institute for Medical Research aims to incorporate the results of genetic screening into medicine.

The researchers will evaluate the relevance of specific genes in terms of their disease risk and clinical utility, and make a direct effort to involve medical professionals.

Unlike some private services, the Coriell project will give participants only that genetic information deemed by an advisory board to be medically… read more

YouTube, social media play new role in presidential debate

Campaigns are gearing up to shape social media reactions in real time
October 3, 2012


The Internet will play an expanded role in tonight’s presidential debate.

YouTube has teamed up with ABC News and Yahoo News to stream the debate.

And as a sign of just how pervasive and crucial social media has become, in some states elected officials are only one degree of “friend” separation from nearly every Facebook account holder in that state, says JD Schlough, a… read more

YouTube unveils live-streaming service

April 13, 2011

YouTube is expanding its video offerings, launching a live-streaming service to complement its catalog of recorded videos.

The video-sharing website is trying to better handle the age of Internet-connected televisions, according to a report from The Wall Street Journal. YouTube is reorganizing its home page around “channels,” or topics, such as sports and arts.

The website is working to include about 20 “premium channels” that would showcase five to… read more

YouTube now supports 4k-resolution videos

July 12, 2010

YouTube has announced that its player now supports 4k, a standard resolution for films that measures 4096×3072 pixels (requiring special equipment to view).

As YouTube Engineer Ramesh Sarukkai explained in the announcement on YouTube’s official blog, “4K is nearly four times the size of 1080p,” and it dwarfs even Imax, which projects films in the slightly smaller 2k format, with its 2048?1080-pixel resolution.
