Startups Seek Perfect Particles To Search And Destroy Cancer

April 21, 2003

Several companies are developing new cancer treatments that send nanoparticles into patients’ bodies to find tumor cells. Once they do, doctors excite the particles with electromagnetic energy to attack the tumor without collateral damage to nearby healthy cells and without the frightening side effects of chemotherapy and radiation: hair loss, nausea, and ravaged immune systems.

Starwars style holographic 3DTV could be a reality by 2018, experts say

December 3, 2008

A 3D television system that would display holographic images floating in mid air could be a reality in households within the next decade, according to findings by a team of University of Aberdeen.

They also expect that within three years, we will see a TV on the market that will use autostereo systems to create 3D images, so that viewers do not need to wear traditional 3D glasses.

State-of-the-art virtual-reality system is key to medical discovery

For team of neurosurgeons and researchers, CAVE2 could revolutionize stroke prevention and treatment
December 13, 2012

Surgeons from the University of Illinois Hospital & Health Sciences Systems Neurosurgery Department view a simulation of the human brain vasculature and cortical tissue in the CAVE2 Hybrid Reality Environment. This project is a collaboration between the University of Illinois at Chicago's (UIC) Electronic Visualization Laboratory (EVL) and Bioengineering Department's Laboratory for Product and Process Design.

A team of neurosurgeons from the College of Medicine at the University of Illinois at Chicago (UIC) recently stepped into CAVE2 — a next-generation, large-scale, 320-degree, immersive, 3-D virtual environment — to solve a vexing problem that presented itself in the arteries of the brain of a real patient.

The method they used could someday benefit hundreds of thousands of Americans who fall… read more

Statins ‘may cut dementia risk’

July 29, 2008

In a five-year study, University of Michigan researchers found that statins–drugs used to lower cholesterol–may cut the risk of dementia by half.

The exact reason why is not yet known, but statins improve blood flow to the brain (by reducing cholesterol-clogging in blood vessels) and reduce levels of insulin.

In another study by Boston University researchers, they found that angiotensin receptor blockers (ARBs)–drugs used to lower… read more

Statistics could help decode ancient scripts

August 18, 2009

A statistical method that picks out the
“information value” of words in a book that could help scholars decode ancient texts like the Voynich manuscript — or even messages from aliens — has been developed by University of Manchester researchers and colleagues.

Stay cool and live longer?

Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why
February 20, 2013

Researchers at the University of Michigan Life Sciences Institute have identified a genetic program that promotes longevity of roundworms (nematodes) in cold environments — and this genetic program also exists in warm-blooded animals, including humans.

“This raises the intriguing possibility that exposure to cold air — or pharmacological stimulation of the cold-sensitive genetic program — may promote longevity in mammals,” said… read more

Staying Out in Front

April 25, 2005

A published road map for the semiconductor industry has the smallest distances between wires on a memory chip shrinking from 90 nanometers today to 65nm in 2007, to 45nm in 2010, to 32nm in 2013 and on down from there.

HP hopes to apply some of its research ideas toward the 32nm milestone. The idea isn’t to replace silicon transistors but to build certain devices, such as ultradense memories,… read more

Stealth Semantic Startup Raises $8.5 Million, Won’t Tell Us Anything

October 14, 2008

Siri, a spinoff of SRI International, plans to commercialize the DARPA-funded CALO (Cognitive Assistant that Learns and Organizes) system, the “largest Artificial Intelligence project in U.S. history.”

It will use AI to automate many of the tasks that people currently conduct manually online. The founders describe themselves as out to change the fundamental ways that people use the Internet, apparently by leveraging artificial intelligence that will learn… read more

Stealth sharks to patrol the high seas

March 2, 2006

Engineers funded by the US military have created a neural implant designed to enable a shark’s brain signals to be manipulated remotely, controlling the animal’s movements, and perhaps even decoding what it is feeling.

The Pentagon hopes to exploit sharks’ natural ability to glide quietly through the water, sense delicate electrical gradients and follow chemical trails. By remotely guiding the sharks’ movements, they hope to transform the animals into… read more

‘Stealth’: A.I. out of control

July 25, 2005

An AI-based unmanned stealth fighter jet, after being hit by lightning, decides to execute a top-secret mission that could result in global thermonuclear war. That’s the theme of the movie “Stealth,” opening this week.

Steering stem cells with magnets

Magnets could be a tool for directing stem cells’ healing powers to treat conditions such as heart disease or vascular disease
July 18, 2013

Magnetsundercells2

By feeding stem cells tiny particles made of superparamagnetic iron oxide nanoparticles, scientists at Emory and Georgia Tech can then use magnets to attract the cells to a particular location in a mouse’s body after intravenous injection.

The type of cells used in the study, mesenchymal stem cells, are not embryonic stem cells. Mesenchymal stem cells can be readily obtained from adult tissues such as… read more

Steering toxic drug-filled nanoparticles to zap cancer, not healthy cells

November 26, 2013

Multifunctionalized drug-loaded nanoparticle

North­eastern researchers are developing sim­u­la­tion soft­ware called Mag­nasim to more accu­rately steer simulated drug-filled mag­netic nanopar­ti­cles to tumor masses where they can safely dis­charge their con­tents.

The drugs used to kill cancer cells are just as toxic to neigh­boring healthy cells, so researchers have long sought a drug delivery method that tar­gets only cancer cells, bypassing the healthy ones.

Func­tional Mag­netic Res­o­nance Imaging (fMRI) is being… read more

Stelarc: Pushing the body’s boundaries

July 26, 2011

Stelarc is a performance artist who explores the capabilities of the human body.

“All of my projects explore alternate anatomical architectures — a body with a third hand, or an extra ear, or an artwork inside a bodily space instead of a public space,” he says. “We are biological bodies, but we are often accelerated, augmented, and enhanced by technology. There may be a time soon when… read more
