News: Living Bacteria in Clothing Could Detect When You Come in Contact with Pathogens or Dangerous Chemicals

While at work, you notice your gloves changing color, and you know immediately that you've come in contact with dangerous chemicals. Bandages on a patient signal the presence of unseen, drug-resistant microbes. These are ideas that might have once seemed futuristic but are becoming a reality as researchers move forward with technology to use living bacteria in cloth to detect pathogens, pollutants, and particulates that endanger our lives.

News: Scientists Are Using the Special Physics of Dragonfly Wings to Create Surfaces That Shred Bacteria on Contact

As drug-resistant bacteria become more commonplace, researchers are looking for new antibacterial strategies to disrupt disease-causing microbes. Some scientists are working to create new drugs, while others are trying out drug combinations. Another group, however, are ditching pharmaceuticals altogether and experimenting with non-drug alternatives.

News: New Study Says Stopping Slimy Biofilms Could Save Thousands a Year from Legionnaires' Disease

In the summer of 1976, 4,000 American Legionnaires descended upon the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania, for a four-day convention. Several days later, many of the attendees experienced symptoms of severe pneumonia. By the beginning of August, 22 people had died. The Centers for Disease Control and Prevention (CDC) estimate that about 180 people were sickened and 29 people died before this mysterious outbreak burnt out.

Hack Like a Pro: Digital Forensics for the Aspiring Hacker, Part 13 (Browser Forensics)

Welcome back, my novice hackers! In this series, we have been exploring how a forensic investigator can find evidence of illegal or illicit activity. Among other things, we have examined the registry and prefetch files for artifacts and have done some rudimentary forensic analysis. For those of you who are seeking career as a forensic investigator or security engineer, this can be invaluable training. For hackers, it might be life-saving.

How To: 10 Common Food Myths Debunked

Common knowledge is a funny thing: it represents a majority's opinion on a particular subject and somehow makes that opinion fact. If that 'fact' goes unopposed and unchallenged, then it is passed on and preserved from one generation to the next—regardless of whether it is true or not.

Hack Like a Pro: Linux Basics for the Aspiring Hacker, Part 13 (Mounting Drives & Devices)

Welcome back, my aspiring hackers! One of those areas of Linux that Windows users invariably struggle with is the concept of "mounting" devices and drives. In the Windows world, drives and devices are automatically "mounted" without any user effort or knowledge. Well, maybe a bit of knowledge. Most Windows users know to unmount their flash drive before removing it, but they usually think of it as "ejecting" it.

News: Coming Soon to a Smartphone Near You: 3D Navigation for Buildings!

Now that everyone has an Android or iPhone in their pocket, there's no excuse for being late to an appointment or job interview. Thanks to that GPS receiver in your smartphone, navigating your way through city streets and highways is a cinch, in or outside of your vehicle. But once you get inside a building, that fancy GPS feature doesn't know what to do. Which direction is the elevator? How do you get to room 819? Where's the nearest fire exit? The bathroom?

How to Make Ferrofluid: The Liquid of the Future

What Is Ferrofluid? Ferrofluid is a black, solvent-based liquid, that, in the presence of a magnetic field, becomes strongly magnetized. The fluid is made up of nanomagnetic particles coated with an "anti-stick" or surfactant compound, suspended in a "carrier", commonly an organic solvent. For mechanical applications, it is used in hard drives and speakers as a lubricant. However, it also has been implemented in artwork, as seen in the video below.
