How To: Make an SMS Intruder Alarm

This tutorial shows you how to create an intruder alarm that sends you text message alerts when motion is detected. This may sound complicated but I am pretty confident any beginner with electronics should be able to do this just fine. The range sensor senses motion and tells your Arduino board to send the text (SMS). So you can leave the intruder detector at home, connected to your network, and still receive the SMS alerts, no matter where you are, as long as you have cell phone service.

News: World's Simplest Electric Train

The trick in the video is that the magnets are made of a conducting material and they connect the battery terminals to the copper wire, so the battery, magnets and copper wire make a circuit that generates a magnet field just in the vicinity of the battery. The geometry means the two magnets are automatically at the ends of the generated magnetic field, where the field is divergent, so a force is exerted on the magnets.

How To: Make Soggy, Wilted Lettuce & Other Leafy Greens Edible Again

Sometimes you've got a head of lettuce that you want to eat but it lacks a certain youth. In other words, it's wilted and browning at the edges. Other times, you get to the grocery store near the end of day and the only lettuce or greens available look a little on the sad side. Never fear. You're not doomed to a meal of fast food or mouthfuls of soggy salad. You can easily revive those leaves and have something crisp, green, and delicious for your next meal, so don't dump it in the trash.

A New Breed of Invertebrate: Half-Rat, Half-Silicone Cyborg Jellyfish

A team of scientists might have just put Jellyfish Art out of business with their new cyborg jellyfish. By arranging the heart cells of a normal rat on a piece of silicone, they've successfully created their own Franken-jellies. When in salt water with a fluctuating electrical field, the rat's heart muscles on the rubbery silicone contract the lobes downward and back up, which mimics the pulsing movement of a young moon jellyfish swimming.

News: How Calcium Sets Off a C Diff Infection

Unfortunately, the very places we go to receive health care put us at risk for becoming infected with superbugs, bacteria exposed to so many antibiotics that they have become immune to their effects. Clostridium difficile (C. diff) is one such bacteria. It causes inflammation of the colon and rampant diarrhea that can have life-threatening consequences. Part of its virulence lies in the tough spores formed by the bacteria. They are responsible for starting infections in the colon and for spre...

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.
