Building complex objects from Lego-like blocks

April 22, 2011

Building blocks for objects (credit: MIT/New Scientist)

Jonathan Bachrach, an MIT researcher, has developed a fabrication machine that will assemble real structures based on digital building blocks — a Lego set for grown-ups.

Once the outline of an object has been determined, the system overlays a 3D grid and assesses which cells will touch the exterior. Then it assigns a particular block shape to each square and decides on its orientation, so that a digital assembler… read more

Real-time 2D to 3D video conversion unveiled

October 8, 2002

New $99 software that converts standard two-dimensional video images into three-dimensional viewing in real time has been unveiled.

The PC-based system requires users to wear special glasses. The technology creates the illusion of depth by generating two images out of one, each tilted and distorted to generate the illusion of depth when combined.

A chip for TV sets is expected in 2003.

Researchers Test Nanoparticle To Treat Cardiovascular Disease In Mice

June 16, 2009

Nanoparticles that can attack plaque — a major cause of cardiovascular disease — have been developed by UC Santa Barbara researchers.

The nanoparticles are lipid-based collections of molecules that form a sphere called a micelle that has a peptide (a piece of protein) on its surface. The peptide binds to the surface of the plaque, rupturing it.

Thinking About Tomorrow

January 30, 2008

The Wall Street Journal looks ahead 10 years–2018–to imagine how technology will change the way we shop, learn and entertain ourselves, and how it will it change the way we get news, protect our privacy, and connect with friends.

Many of the changes will come from a couple of rapidly improving technologies: mobile devices and global positioning systems.

Molecules used as information processors

September 8, 2005

Chemists at Queen’s University Belfast are exploring the capabilities of molecules that act like conventional computers but in spaces only a few nanometers across.

Molecular information processors placed in nano-spaces can gather, process and supply valuable data on how chemistry and biology function at this tiny scale. Molecules can also be used as information processors in medical and other applications.

Sensors Gone Wild

October 27, 2002

The real goal of a $40 million experiment is to explore the uses of intelligent sensors, a technology whose promise suddenly seems huge. The applications for this “embedded intelligence” are vast and profound. Eventually large swaths of the earth will communicate with the digital realm using millions of miniature sensors. Sensors will be placed in bridges to detect and warn of structural weakness and in water reservoirs to spot hazardous… read more

Human Eye Inspires Advance In Computer Vision

June 23, 2009

Inspired by the behavior of the human eye, Boston College computer scientists have developed a technique that lets computers see objects as fleeting as a butterfly with nearly double the accuracy and 10 times the speed of earlier methods.

Sniffling mice raise therapy hope

February 5, 2008

In a study led by London’s Imperial College, scientists have created a mouse that can catch a cold, raising hopes of new ways to treat serious respiratory conditions and asthma.

It had been thought rhinoviruses, which cause most human colds and can trigger asthma attacks, could only affect higher primates.

Rhinoviruses were discovered 50 years ago, but the failure to find a way to infect small animals had… read more

It’s A Whole New Web

September 20, 2005

“Web 2.0″ is shaking up a raft of industries as people individually and collectively program their own Web.

By the millions, they’re gathering and disseminating their own news with blogs and podcasts, creating customized article and photo feeds from their favorite sites and even annotating them with helpful text tags that others can search for. And they’re producing their own entertainment on video, social-networking, game, and photo-sharing sites.

An in-depth analysis of how the caffeine in coffee, tea, and other foods seems to protect against conditions such as Alzheimer’s disease and heart disease at the most fundamental levels has been reported by researchers at Universidad Autonoma Metropolitana-Iztapalapa in Mexico.

The researchers describe evidence that coffee is one of the richest sources of healthful antioxidants in the average person’s diet. Some of the newest… read more

Nanowires within nanowires

November 13, 2002

Harvard University researchers have synthesized nanowires that are only 50nm in diameter, containing a germanium core surrounded by a silicon shell. They also made “triple decker” wires of silicon, silicon oxide and germanium.

They have used these approaches to prepare new devices called nanowire field-effect transistors. Working with researchers from Intel, the team also plans to integrate these transistors with conventional semiconductor processing to produce advanced hybrid devices.

Toyota Develops Mind-Controlled Wheelchair

June 30, 2009

Toyota researchers have built a brain/machine interface that controls a wheelchair using EEG sensors placed over the areas of the brain that control motion, with plans for a wide range of applications in medicine and nursing care.

Researchers reverse bacterial resistance to antibiotics

Based on tested strategic schedule of antibiotic cycling
May 7, 2015

Antibiotic resistance tests: Bacteria are streaked on the dish and on which antibiotic impregnated white disks are placed. Bacteria in the culture on the left are susceptible to the antibiotic in each disk, as shown by the dark, clear rings where bacteria have not grown. Those on the right are fully susceptible to only three of the seven antibiotics tested (credit: Graham Beards/Wikimedia Commons)

Biologist Miriam Barlow of the University of California, Merced, and mathematician Kristina Crona of American University of Washington, DC have found a way to return bacteria to a pre-resistant state to help doctors deal with the growing problem of resistant bacteria. In research published in the open-access journal PLOS ONE, they show how to verify treatment options for a family of 15 antibiotics used to fight… read more

R Is for Robot

October 2, 2005

UC San Diego human-robot researchers hope to develop classroom teaching machines with a “human touch” and robotic companions that can develop personal relationships.

Renewables may supply 80 percent of our energy by 2050

May 12, 2011

Almost 80 percent of the world’s energy could come from renewable energy sources by 2050, according to the IPCC’s Special Report on Renewable Energy Sources and Climate Change Mitigation.

The report’s super-green scenario assumes we become so energy efficient that the predicted 9-billion-strong population of 2050 uses less energy than 7 billion of us do today — 407 exajoules per year, compared with 490 exajoules.

However, without green… read more
