A new Mayo Clinic study confirms the use of smartphones medical images to evaluate stroke patients in remote locations through telemedicine.

“Essentially what this means is that telemedicine can fit in our pockets,” says Bart Demaerschalk, M.D., professor of Neurology, and medical director of Mayo Clinic Telestroke.

“For patients this means access to expertise in a timely fashion when they need it… read more

How to use Amazon Cloud supercomputers to view molecules in remarkable detail

Cloud computing code speeds processing of data-intensive microscopy data
February 5, 2013

Salk Institute for Biological Studies researchers have shared a how-to secret for biologists: code for Amazon Cloud that significantly reduces the time necessary to process data-intensive microscopic images.

The method promises to speed research into the underlying causes of disease by making single-molecule microscopy of practical use for more laboratories.

“This is an extremely cost-effective way for labs to process super-resolution images,” says … read more

Antifreeze, cheap materials may lead to low-cost solar energy

July 5, 2013


Engineers at Oregon State University have determined that ethylene glycol, commonly used in antifreeze products, may be the key to making solar cells that cost less and avoid toxic compounds.

Ethylene glycol functions well in a “continuous flow” reactor — an approach to making thin-film solar cells that is easily scaled up for mass production at industrial levels, they note.

Happy or sad? You might not see that ad, if Microsoft Kinect can figure out your mood

June 15, 2012


Microsoft has applied for a patent for  targeting ads to users based on their emotional state, using a Kinect type device, GeekWire reports.

Do you look happy? You’ll see ads for vacation packages and consumer electronics, but not weight-loss programs or self-help products. Do you look sad? You won’t see that over-the-top animated ad for children’s birthday parties at the local bowling alley. Feeling frustrated? It’s PC support ads for… read more

A ‘Google’ for chemistry invents best path to new compounds in seconds

Giant network links all known compounds and reactions
August 24, 2012


Northwestern University scientists have connected 250 years of organic chemical knowledge into one giant computer network called Chematica — a chemical “Google” on steroids.

A decade in the making, the software optimizes syntheses of drug molecules and other important compounds, combines long (and expensive) syntheses of compounds into shorter and more economical routes, and identifies suspicious chemical recipes that could lead to chemical weapons.

Craig Venter imagines a world with printable life forms

October 18, 2012


Craig Venter imagines a future where you can download software, print a vaccine, inject it, and presto! Contagion averted.

“It’s a 3-D printer for DNA, a 3-D printer for life,” Venter said at the inaugural Wired Health Conference in New York City, Wired Science reports.

The geneticist and his team of scientists are already testing out a version of his digital biological converter, or “teleporter.”… read more

Most of the harmful mutations in people arose in the past 5,000 to 10,000 years

European Americans have a larger proportion of potentially harmful variants than African Americans --- probably an artefact of their original migration out of Africa

The human genome has been busy over the past 5,000 years. Human populations have grown exponentially, and new genetic mutations arise with each generation, says Nature News.

Humans now have a vast abundance of rare genetic variants in the protein-encoding sections of the genome.

A study published in Nature now helps to clarify when many of those rare variants arose.

Researchers used deep sequencing to locate… read more

New carbon nanotube fiber acts like textile thread, conducts electricity and heat like a metal wire

Unmatched combination of strength, conductivity, flexibility
January 11, 2013


Scientists from Rice University, the Dutch firm Teijin Aramid, the U.S. Air Force, and Israel’s Technion Institute have unveiled a new carbon nanotube (CNT) fiber that looks and acts like textile thread and conducts electricity and heat like a metal wire.

In this week’s issue of Science, the researchers describe an industrially scalable process for making the threadlike fibers, which outperform commercially available high-performance materials… read more

Voyager 1 embarks on historic journey into interstellar space

September 13, 2013


NASA‘s Voyager 1 spacecraft is now officially the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun.

New and unexpected data indicate Voyager 1 has been traveling for about one year through plasma, or ionized gas, present in the space between stars. Voyager is in a transitional region immediately outside… read more

LSD found successful in treating alcoholics

March 9, 2012


Teri Krebs and Pål-Ørjan Johansen, researchers at the Norwegian University of Science and Technology (NTNU), have taken a closer look at experiments in the 1950s, ’60s and ’70s, treating alcoholics with LSD.

The researchers found six different studies of LSD and alcoholism that were scientifically sound, involving a total of 536 people. They showed that a single dose of LSD, provided for treatment purposes, helped… read more

First 3D ghost images from a single pixel

January 29, 2013

3D ghost imaging

Shanghai Institute of Optics and Fine Mechanics in China physicists have designed and built a remote-sensing “ghost imaging” device that uses a single pixel to record three-dimensional images, MIT Technology Review reports.

Ghost imaging is the extraordinary technique of bouncing a laser beam off an object and making high quality images from the reflected light using a single pixel. This single pixel is used to record data… read more

Iris (Siri for Android) released

October 24, 2011


Iris for Android, a Siri lookalike, is now available on the Android Market, Gizmodo reports.

Iris (Siri backwards), emulates what Siri on the iPhone 4S does: you tap a mic, you talk, and Siri responds to you. Siri could lead to a real AI, Wired blogger Jon Stokes says.

The same SRI International defense project that gave birth to Siri —  CALO… read more

Clothes will sew themselves in DARPA’s sweat-free sweatshops

June 11, 2012


DARPA has awarded $1.25 million to fully automate the sewing process, Wired Danger Room reports.

One 2010 estimate put the military’s annual clothing budget at $4 billion dollars.

SoftWear Automation Inc., has so far developed “a conceptual” version of the automated system. According to its website, it is a robotic system that relies on an extremely precise monitoring of a given fabric’s “thread count”… read more

Are restrictions to scientific research costing lives?

September 6, 2012


In “Censors on Campus,” Index on Censorship magazine asks whether lives might be saved by making vital research freely available.

Some parts of Asia and Africa the fight against malaria is severely hampered because doctors and researchers are denied full access to the 3,000 articles published on the disease each year. At the same time, scientists living and working in developing countries are prevented from becoming global… read more
