Acoustic levitation allows small objects, like droplets of liquid, to float. Unless you travel into the vacuum of space, sound is all around you every day. But most of the time, you probably don't think of it as a physical presence. You hear sounds; you don't touch them. The only exceptions may be l...

You can do so much more on a iPad than merely type! If you're an iPad user -- or perhaps thinking about becoming one -- you've probably considered the various ways the device can make your life a little more fun. Sure, you can read books, play games or watch movies, but what about using your iPad to...

The other major challenge was the development of ”cool” atmosphere models characterised by strong molecular absorptions and, for the coolest objects, by condensation processes (see Allard et al (1997) and references therein). As brown dwarf observations deliver data with increasing accuracy and leve...

The awareness of the impact one race has on its immediate environment --. The waste stream as a whole -- is changing the culture of consumption in triathlons. In 2007, the Council for Responsible Sport was founded by the Directors of the Freshwater Trust Portland Triathlon with the goal of helping r...

And when police are dispatched, they don't go to the place where a 911 caller alerted them. They go to where the actual shot was picked up by the sensors. Teachman, referring to the pin on the alert map that marks the spot of the shot. High-tech tools can create a false justification for the broken ...

The hybridization and genetic alteration of wheat continued for centuries, becoming more advanced as technology developed. Gene alteration became highly specific, with scientists creating disease-resistant varieties and fine-tuning nutritional content. In the mid-20th century, biologists started usi...

Around the mid-1950s, airborne ski guides made the switch from airplanes to helicopters. While airplanes were becoming easier to land on short runways, those flat runways were still a requirement. Also, while planes could carry more people, helicopters could get them atop the narrow, sky-kissed ridg...

Like backscatter X-ray machines, millimeter wave scanners produce detailed full-body images of passengers, but they do it with ultrahigh-frequency millimeter wave radiation rather than X-rays. If you went on name alone, you might think "advanced imaging technology machines" could help doct...

Nintendo also looked to Xbox Live and its mega hit "Halo" for inspiration in allowing the DS to connect gamers to one another. Up to 16 people can play each other on the DS, and with a wireless LAN connection, that number could increase indefinitely. Add in the possibility of multiple play...

For this task, you can only use one set of rules at a time to organize the shelf. For example, you could put the books in order by author's last name, by title or even by height. Even if you combine these strategies, one still has to take priority over the other, such as by author first, then by tit...

With that in mind, we're going to compare and contrast the two technologies across a variety of parameters, starting with the kind of energy they emit. X-rays or Millimeter Waves? A volunteer stands inside a backscatter scanner during a demo at the Transportation Security Administration's Systems In...

In this article, we'll cover the regulations, planning and features of rural landscape design. If you know about a patch of unused land somewhere, read on to learn how to beautify it. Generally, these restrictions protect natural elements, preserve rural spaces and govern future development while ma...

As it happened, work toward that car had been underway since early 1982, just as the reborn GT and H.O. V-8 were starting to rekindle the old Mustang excitement. Initiated as project SN8 -- "sporty car, North America, 8" -- this effort envisioned a smaller, lighter pony like the old Mustan...

So, the EU and even more so, NATO, have crept farther and farther east. The Baltic States, which were once part of the former Soviet Union, are in NATO, but also the East European states of Czech Republic, Slovakia, Poland, Romania, Bulgaria and Montenegro, with North Macedonia as the most recent me...

By comparison, jackhammers (sometimes called pneumatic drills or demolition hammers) make quick work of even really hard surfaces like highways, patios and rock walls. That doesn't mean jackhammers are easy to use. They tend to be unwieldy, with some weighing nearly 100 pounds (45 kilograms), meanin...

Electronic cigarettes closely resemble the real thing. You're at your favorite restaurant, enjoying a meal. A diner at the next table is puffing on a cigarette, letting out a cloud of smoke. Because smoking isn't allowed in the restaurant, you're thinking about asking the smoker to put the cigarette...
