The Stranger Side of CHI 2009

April 14, 2009

A wearable system that lets a user control a computer using eye movements, and devices that sync when they touch to show related photos are among the odder inventions demoed at the Computer-Human Interaction Conference in Boston last week.

Is anything nuclear ever really super safe, small and simple?

March 16, 2011

The Japanese nuclear accidents come down to the simple fact that nobody back in the 1960s designed nuclear plants to run for 40 years, then go through an 8.9 earthquake, says blogger Robert Cringely.

Japan now needs increased generating capacity fast. Toshiba’s 4S (Super Safe Small and Simple) reactor cores are like nuclear building blocks, built on a factory production line and transported by truck to be… read more

A Working Brain Model

November 28, 2007

Scientists in Switzerland working with IBM researchers have shown that their computer simulation of the neocortical column, arguably the most complex part of a mammal’s brain, appears to behave like its biological counterpart.

By demonstrating that their simulation is realistic, the researchers say, these results suggest that an entire mammal brain could be completely modeled within three years, and a human brain within the next decade.

Virtual-Reality Video Game Helps Link Depression To Specific Brain Area

March 2, 2007

Scientists are using a virtual-reality, three-dimensional video game that challenges spatial memory as a new tool for assessing the link between depression and the hippocampus, the brain’s memory hub.

Enzyme ‘Ink’ Shows Potential for Nanomanufacturing

April 23, 2004

Enzymes can be used to create nanoscale patterns on a gold surface, Duke University engineers have demonstrated, representing an important advance in nanomanufacturing.

They used an enzyme called DNase I as an “ink” in a process called dip-pen nanolithography (for nanoscale etching or writing). The dip-pen allowed them to inscribe precise 100-nanometers-wide stripes of DNase I ink on a gold plate, which they had previously coated with a thick… read more

High definition nanomovies reveal how RNA dances with drug partners

April 21, 2009

University of Michigan and University of California, Irvine researchers have combined two methods — nuclear magnetic resonance and molecular dynamics simulation — to produce high-definition movies showing how RNA in motion changes shape and binds with drug molecules.

Switching device enables ultrafast quantum Internet

March 23, 2011

Researchers have developed a new switching device that can route quantum bits at very high speeds along a shared network of fiber-optic cable without losing the embedded entanglement information, says Prem Kumar, AT&T Professor of Information Technology at Northwestern University.

The researchers used pairs of polarization-entangled photons emitted into standard telecom-grade fiber. One photon of the pair was transmitted through the all-optical switch. Using single-photon detectors,… read more

Stanford researchers produce short-term reversal of skin aging in mice

December 5, 2007

Researchers at the Stanford University School of Medicine have reversed the effects of aging on the skin of mice, at least for a short period, by blocking the action of a single critical protein, NF-kappa-B.

After two weeks, the skin of 2-year-old mice had the same genes active as cells in the skin of newborn mice.

The work backs up the theory that aging is the result of… read more

Worldwide warning issued on mercury-contaminated fish

March 12, 2007

The health risks posed by mercury contaminated fish is sufficient to warrant issuing a worldwide general warning to the public–especially children and women of childbearing age–to be careful about how much and which fish they eat.

The declaration, developed at the Eighth International Conference on Mercury as a Global Pollutant, is a synopsis of the latest scientific knowledge about the danger posed by mercury pollution.

Probe to detect cancer in intestines

May 5, 2004

A UC Irvine research team has received a $2.9 million National Institutes of Health grant to develop a microscopic probe for detecting and treating pre-cancerous and malignant tumors in humans.

The probe would guided through the esophagus, stomach and colon to determine if tumors are growing on the wall of the intestine. It would be remotely controlled by a surgeon operating an endoscope. The probe uses optical coherence tomography… read more

Making Heart Cells

April 28, 2009

Scientists at the Gladstone Institute of Cardiovascular Disease have discovered that three proteins — a pair of transcription factors and a protein that helps loosen tightly wound DNA — could direct certain embryonic cells to form cardiac-muscle cells, called cardiomyocytes.

These cells not only produced proteins characteristic of early heart cells, but they eventually started to beat.

Lightning Bolts within Cells: a new nanoscale tool reveals strong electric fields inside cells

December 11, 2007

Using novel voltage-sensitive nanoparticles, University of Michigan researchers have found electric fields inside cells as strong as those produced in lightning bolts.

Previously, it has only been possible to measure electric fields across cell membranes, not within the main bulk of cells.

Testing these nanoparticles in the internal fluid of brain-cancer cells, researchers found electric fields as strong as 15 million volts per meter, perhaps five times stronger… read more

Artificial lymph node transplanted into mice

March 16, 2007

An artificial lymph node has been transplanted into mice, where it successfully produced immune cells.

The new form of bioengineered tissue marks a significant step towards transplanting an entire immune system into patients dying of AIDS, cancer or other diseases.

Google spans entire planet with GPS-powered database

Wired Enterprise reports that Google has published a research paper (open access) detailing Spanner, which Google says is the first database that can quickly store and retrieve information across a worldwide network of data centers while keeping that information “consistent” — meaning all users see the same collection of information at all times.

Spanner borrows techniques from some of the other massive software platforms Google built for its data centers,… read more

Robots: Today, Roomba. Tomorrow…

May 11, 2004

Roomba is a first step, but there are many tasks within the home that are ripe for robotic automation, says iRobot CEO Colin Angle.
