As the liquid crystals align in electric fields, it helps to align the nanotubes — changing the electrical structure of the materials. You can see the thermal output from the material during this “training” process. Bright colors represent localized heati

Evolution-in-materio: Carbon Nanotube Computing?

April 9, 2015 4:29 pm | by American Institute of Physics (AIP) | News | Comments

As we approach the miniaturization limits of conventional electronics, alternatives to silicon-based transistors — the building blocks of the multitude of electronic devices we’ve come to rely on — are being hotly pursued. Inspired by the way living organisms have evolved in nature to perform complex tasks with remarkable ease, a group of researchers is exploring similar “evolutionary” methods to create information processing devices.

Ransomware infiltrates a computer after a user clicks on a link or attachment in an e-mail. It can also attack when a user visits a Web site, including well-known ones with good security systems.

A Q&A about the Malicious Software Known as Ransomware

April 9, 2015 4:23 pm | by Joyce M. Rosenberg, AP Business Writer | News | Comments

Ransomware is a growing threat to computer users, who can suddenly find they're unable to open or use their files when their machines are infected. The malicious software can attack any user — an individual, small business, Fortune 500 company or a government agency.

Obama Signs Order Creating New Cyber Sanctions Program

April 9, 2015 9:59 am | by Ken Dilanian, AP Intelligence Writer | News | Comments

President Barack Obama authorized a new U.S. government approach to deterring cyberattacks on April 8, 2015: financial sanctions against malicious overseas hackers and companies that knowingly benefit from the fruits of cyberespionage. The latter category could include state-owned corporations in Russia, China and elsewhere, setting the stage for major diplomatic friction if the sanctions are employed in that way.

Nurses practice taking blood pressure and collecting medical history with a traditional human patient simulator system. Its face is completely inexpressive, and its lips do not move when it "talks." Speech is either pre-recorded, or voiced by the clinical

Human Patient Simulators: How Robots can Help Build Better Doctors

April 9, 2015 9:53 am | by NSF | News | Comments

A young doctor leans over a patient who has been in a serious car accident and invariably must be experiencing pain. The doctor's trauma team examines the patient's pelvis and rolls her onto her side to check her spine. They scan the patient's abdomen with a rapid ultrasound machine, finding fluid. They insert a tube in her nose. Throughout the procedure, the patient's face remains rigid, showing no signs of pain.

New Technology Making Drones Safer and Smarter

April 8, 2015 3:27 pm | by University of Zurich | News | Comments

Researchers at the University of Zurich have unveiled new technology enabling drones to recover stable flight from any position and land autonomously in failure situations. It will even be possible to launch drones by simply tossing them into the air like a baseball or recover stable flight after a system failure. Drones will be safer and smarter, with the ability to identify safe landing sites and land automatically when necessary.

The book assumes no formal statistical training on the part of the reader so the language is everyday plain. It seeks to clarify basic concepts and NOT teach the intricacies of the mathematics. Still, the book has much to recommend it.

Statistics Done Wrong: The Woefully Complete Guide

April 8, 2015 3:05 pm | by John A. Wass, Ph.D. | Articles | Comments

This delightful and informative guide from my friends at No Starch Press comes with the following cover blurb: “Statistics Done Wrong is a pithy, essential guide to statistical blunders in modern Science that will show you how to keep your research blunder-free.” It is somewhat pithy, but as to blunder free, I will quote the old maxim that “nothing is foolproof, as fools are so very clever.” Still, the book has much to recommend it.

Researchers have long believed that supercomputers give universities a competitive edge in scientific research, but now they have some hard data showing it’s true. A Clemson University team found that universities with locally available supercomputers were more efficient in producing research in critical fields than universities that lacked supercomputers.
