Projecting a robot’s intentions

October 29, 2014 1:27 pm | by Jennifer Chu, MIT | Comments

Inside Massachusetts Institute of Technology’s Building 41, a small, Roomba-like robot is trying to decided where to go. As the robot considers its options, its “thoughts” are projected on the ground in the form of different colored dots and lines. This new visualization system, called “measurable virtual reality”, combines projectors with motion-capture technology and animation software to project a robot’s intentions in real time.

Emergent behavior lets bubbles “sense” environment

October 27, 2014 12:46 pm | Comments

Tiny, soapy bubbles can reorganize their membranes to let material flow in and out in response to the surrounding environment, according to new research. This behavior could be exploited in creating microbubbles that deliver drugs or other payloads inside the body, and could help us understand how the very first living cells on Earth might have survived billions of years ago.

New dent in HIV-1’s armor

October 27, 2014 8:01 am | by The Salk Institute | Comments

Like a slumbering dragon, HIV can lay dormant in a person’s cells for years, evading medical treatments only to wake up and strike at a later time, quickly replicating itself and destroying the immune system. Scientists at the Salk Institute have uncovered a new protein that participates in active HIV replication. The new protein, called Ssu72, is part of a switch used to awaken HIV-1 from its slumber.

Scientists to use tiny particles to fight big diseases

October 23, 2014 12:49 pm | Comments

A group of scientists in Florida have combined medicine and advanced nanotechnological engineering to create a smarter, more targeted therapy that could overcome the most lethal gynecologic cancer. The technology involves combining Taxol, a chemotherapy drug, with magneto-electric nanoparticles that can penetrate the blood-brain barrier.

Researchers record sight neurons in jumping spider brain

October 22, 2014 2:43 pm | Comments

Though neurobiologists have tried for half a century to better understand the brains of jumping spiders, no one has succeeded. The liquid in spiders’ bodies is pressurized, and they move with hydraulic pressure and muscles. But with a new technique using a tiny tungsten recording electrode, researchers have made recordings of neurons associated with visual perception inside the poppy seed-sized brain the spider.

When emotions control objects

October 20, 2014 11:51 am | by Cécilia Carron, EPFL | Comments

Sensors developed by SmartCardia, a spin-off from EPFL in Switzerland, use various biological vital signs to transmit data to a host of everyday objects. This data, which includes heart rate, respiration activity, skin conductivity and physical exertion, can be used dim a light, control immersive playing on a computer, and track yoga exercises in real time.

R&D 100 Award Video: Calcium Loop for Carbon Capture

October 20, 2014 9:07 am | by Lindsay Hock, Managing Editor | Comments

Carbon capture and sequestration isn’t only suitable for new power plants, but more essential in retrofitting existing ones. Because of this retrofitting nature, carbon capture and sequestration is regarded by the International Energy Agency as the single technology most capable of carbon dioxide reduction in the world and could account for more than 20% of global carbon dioxide abatement by 2050.

The Jefferson Project at Lake George unveils state-of-the-art data visualization laboratory

October 17, 2014 11:47 am | Comments

A partnership between Rensselaer Polytechnic Institute, IBM, and the FUND for Lake George has developed preliminary models of key natural processes within the watershed. A network of 12 sensor platforms including vertical profilers and tributary monitoring stations are now being deployed in Lake George and its tributaries, providing an unprecedented amount of data for researchers that will be interpreted at a new visualization laboratory.

Innovations being commercialized to improve radiation detection, adhesives and sealants

October 15, 2014 8:17 am | Comments

Officials at a Chicago-based startup, Sagamore-Adams Laboratories LLC, say innovations discovered in Purdue University's School of Nuclear Engineering are being commercialized to address challenges in improving radiation detection and making sealants and adhesives safer. They have developed technology that could lead to radiation sensors that cost less and provide better information than traditional sensors.

First observations of atoms moving inside bulk material

October 14, 2014 8:23 am | by Christopher R. Samoray, Oak Ridge National Laboratory | Comments

Researchers at Oak Ridge National Laboratory have obtained the first direct observations of atomic diffusion inside a bulk material. The research, which could be used to give unprecedented insight into the lifespan and properties of new materials, is published in Physical Review Letters.

DNA’s security system unveiled

October 13, 2014 9:04 am | by Bill Hathaway, Yale Univ. | Comments

As befitting life’s blueprint, DNA is surrounded by an elaborate security system that assures crucial information is imparted without error. The security is provided by a double membrane perforated by protein channels that block unwanted material from entering the nucleus and promote entry of key messengers.

Teams set new records for silicon quantum computing

October 13, 2014 8:55 am | Comments

Two research teams working in the same laboratories in Australia have found distinct solutions to a critical challenge that has held back the realization of super powerful quantum computers. The teams created two types of quantum bits, or "qubits", which are the building blocks for quantum computers, that each process quantum data with an accuracy above 99%. They represent parallel pathways for building a quantum computer in silicon.

New sensor uses radio waves to detect subtle changes in pressure

October 10, 2014 2:09 pm | Comments

Stanford Univ. engineers have invented a sensor that uses radio waves to detect subtle changes in pressure. Already used to monitor brain pressure in laboratory mice as prelude to possible use with human patients, this pressure-sensing technology relies on a specially designed rubber and could lead to touch-sensitive “skin” for prosthetic devices.

Snakes and snake-like robots show how sidewinders conquer sandy slopes

October 10, 2014 8:15 am | by John Toon, Georgia Tech and Byron Spice, Carnegie Mellon Univ. | Comments

The amazing ability of sidewinder snakes to quickly climb sandy slopes was once something biologists only vaguely understood and roboticists only dreamed of replicating. By studying the snakes in a unique bed of inclined sand and using a snake-like robot to test ideas spawned by observing the real animals, both biologists and roboticists have now gained long-sought insights, including how sidewinders effectively traverse sandy slopes.

Nanoparticles get a magnetic handle

October 9, 2014 10:50 am | by David L. Chandler, MIT News Office | Comments

A long-sought goal of creating particles that can emit a colorful fluorescent glow in a biological environment, and that could be precisely manipulated into position within living cells, has been achieved by a team of researchers at Massachusetts Institute of Technology and several other institutions. The new technology could make it possible to track the position of the nanoparticles as they move within the body or inside a cell.
