What is the best shape for cancer-fighting nanoparticles?

June 5, 2012

Scientists at The Methodist Hospital Research Institute (TMHRI) and six other institutions suggest that nanoparticles ought to be disc-shaped, not spherical or rod-shaped, when targeting cancers at or near blood vessels.

“The vast majority — maybe 99 percent — of the work being done right now is using nanoparticles that are spherical,” said TMHRI biomedical engineer Paolo Decuzzi, Ph.D., principal investigator for both projects. “But evidence… read more

What Is I.B.M.’s Watson?

June 17, 2010

IBM scientists have been developing a supercomputer called “Watson” that they expect will be the world’s most advanced “question answering” machine, able to understand a question posed in everyday natural language by accessing information in tens of millions of documents.

The producers of “Jeopardy!” have now agreed to pit Watson against some of the game’s best former players as early as this fall as a test of Watson’s capabilities… read more

Plan X (credit: DARPA)

On October 15 and 16, DARPA outlined its plans for Plan X to more than 350 software engineers, cyber researchers, and human-machine interface experts and solicited their feedback, in preparation for anticipated release in the next month of the program’s Broad Agency Announcement (BAA), to be posted to www.fbo.gov.

DARPA‘s Plan X program,. the first of its kind, will attempt to create revolutionary technologies for… read more

What is 5G and when can I get it?

March 25, 2015

Imagine being able to download a full-length 8GB HD movie to your phone in six seconds (versus seven minutes over 4G or more than an hour on 3G) and video chats so immersive that it will feel like you can reach out and touch the other person right through the screen.

That’s the vision for the 5G concept — the next generation of wireless networks — presented at the… read more

What if your laptop knew how you felt?

December 22, 2006

Computers can now analyze a face from video or a still image and infer almost as accurately as humans (or better) the emotion it displays.

Developed at MIT, “Mind Reader” uses input from a video camera to perform real-time analysis of facial expressions.

What if We Ran Universities Like Wikipedia?

October 19, 2010

David J. Staley has laid out the findings of a focus group he conducted asking educators what a college would look like if it ran like Wikipedia.

First, it wouldn’t have formal admissions, said Mr. Staley, director of the Harvey Goldberg Center for Excellence in Teaching at Ohio State University. People could enter and exit as they wished. It would consist of voluntary and self-organizing associations of teachers and… read more

What if there is only one universe?

June 8, 2009

Theories of cosmology based on a multiverse are flawed, says Lee Smolin, author of the bestselling science book The Trouble with Physics and a founding member and research physicist at the Perimeter Institute for Theoretical Physics.

Smolin points out why a timeless multiverse means that our laws of physics are no longer determinable from experiment and how the connection between fundamental laws, which are unique and applicable universally from… read more

What if quantum entanglement worked on the macroscopic level?

July 26, 2013

entangled photons

Quantum entanglement works for photons, and even molecuiles, but what about larger objects?

University of Geneva (UNIGE) researchers managed to entangle crystals in 2011, but now they have entangled two optic fibers, populated by 500 photons.

To do this, the team first created an entanglement between two fiber optics on a microscopic level before moving it to the macroscopic level. The entangled state survived… read more

What if Humans were Designed to Last?

March 30, 2007

Experts across fields were challenged to imagine a new way to solve the problems of human aging by fiddling with physiology and tinker with the inner mechanics of life at the cellular or even molecular level.

What if Bionics Were Better?

September 26, 2006

A tiny population of early adopters eager to test bionics by choice rather than out of need is emerging.

What I Meant to Say Was Semantic Web

October 22, 2007

Radar Networks has introduced Twine, a Web 3.0 service that uses semantic Web technology to improve sharing information with friends and coworkers.

Twine is intended to let you suck in email, bookmarks, RSS news feeds, websites, photos, videos, database and any other digital information. Then it tries to make sense of it by extracting and categorizing information automatically.

Individuals can sign up to be invited to the beta… read more

What happens when we all drive electric vehicles?

March 5, 2015

(credit: Hasselt University)

The European Union predicts that electric vehicles (EV) could be in mass production by 2020. But what might be their impacts, such as new demands on electrical distribution grids and on how and where we travel?

The EU DATA SIM project, a  consortium of nine partners from seven countries with EUR 2,3 million investment from the EU, was created for that purpose.

It has… read more

What happens when silicon can shrink no more?

December 8, 2008

Crossbar switching arrays made from self-assembled semiconducting nanowires or rotaxanes and graphene transistor channels are among the emerging innovations that promise to overcome the limitations of silicon as a transitor base material.

Long-term galactic cosmic ray exposure leads to dementia-like cognitive impairments
May 4, 2015

radiation effects

Exposure to highly energetic charged particles — much like those found in the galactic cosmic rays that bombard astronauts during extended spaceflights — causes significant damage to the central nervous system, resulting in cognitive impairments, according to a UC Irvine radiation oncology open-access study appearing in the May 1 edition of Science Advances.

“This is not positive news for astronauts deployed on a two- to three-year round… read more

What happens during the brain’s ‘resting state’?

September 20, 2012

fMRI images

Over the past few years, some researchers have been adding a bit of down time to their study protocols, Nature News reports. While subjects are still lying in the functional magnetic resonance imaging (fMRI) scanners, the researchers ask them to try to empty their minds. The aim is to find out what happens when the brain simply idles. And the answer is: quite a lot.

Some circuits… read more
