A Visual Guide to How Many Fruits and Veggies You Should Eat for a Serving [Food]

A Visual Guide to How Many Fruits and Veggies You Should Eat for a ServingWe all grew up knowing the "food pyramid" by heart, but it wasn't easy to apply to the real world because it was all based on servings. If all food came in packages by the serving, then everything would make sense, but that's not the case. Food site CHOW's handy visual guide for popular fruits and vegetables attempts to fix that problem.

Fruits like oranges, peaches, and pears are no surprise, since they're roughly the "fist-sized" portion that the serving generally sticks to, but other fruits aren't so easy to pin down, and it's usually the ones that are the most fun to eat. So, just how many grapes make up a "serving" of fruit? Turns out it's 32.

Vegetables can be even harder than fruit, but the guide makes it easy (now, if only eating certain vegetables were as easy). Asparagus lovers will be happy to know that it only takes an average of four spears to make a serving—but broccoli haters will be displeased to know that it takes 16 baby trees to get the same result.

The guide is available as a handy, two-page PDF, so you can post it right up on the fridge. CHOW also recommends you go straight to the CDC's website and use their calculator to find out exactly how many servings of each that you need on a daily basis, and to use the guide as a reference point until you get the hang of it.

Miro Is a Full-Featured Media Player with Android Syncing, BitTorrent, and Video Conversion [Video]

Source: http://lifehacker.com/5804683/miro-4-becomes-a-full+featured-desktop-media-player-with-android-syncing-bittorrent-downloading-and-video-conversion

Windows/Mac/Linux: Previously mentioned Miro has been around for awhile, but for many it was little more than yet another alternative video player. Today, though, Miro has overhauled its app into a full-featured media library designed to sync with Android.

Android users may see an immediate resemblance to previously mentioned DoubleTwist, and Miro's Android syncing puts it in a position as a great alternative. While it doesn't have wireless sync like DoubleTwist, it does have a few advantages over its competitors, like full podcast support and a built-in video converter that will convert your videos to a compatible format for your mobile device.

It also has a few other cool features that aim to make it worthy of a desktop media player, and not just a syncing program: For example, you can share media across your network and buy music directly from the Amazon MP3 store. It even has its own BitTorrent client and custom search engine built-in, so you can download those videos direct to your media library. Check out the video above for more info on the app's overhaul, and hit the link below to try it out.

Metamaterial Lenses Could Allow Easy Wireless Power Transmission [Research]

Metamaterial Lenses Could Allow Easy Wireless Power TransmissionMetamaterials could make it possible to transmit wireless power while avoiding the complications associated with microwaves or lasers, engineers at Duke University say.

The material would be situated between a power source and a device to be charged, and it would serve as a sort of a bridge so that there appeared to be no space between the transmitter and the recipient.

Tiny amounts of energy can already be transmitted across small distances, such as radio frequency identification devices or even near-field communications. But it would be dangerous to scale up power transmission to the levels needed for, say, charging a cell phone - high-powered microwave or laser devices would likely fry the device you are trying to charge.

A metamaterial could facilitate a simpler, safer energy transfer, according to Yaroslav Urzhumov, assistant research professor in electrical and computer engineering at Duke. It would act as a lens to keep the energy focused, allowing it to travel more readily through open space without scattering.

This hypothetical metamaterial would consist of an array of thin conducting loops made of the same copper-fiberglass material used in printed circuit boards, and it would look like a set of Venetian blinds, according to a linktextDuke news release.

Metamaterials have already been used to focus imaging sound waves to sharpen sonar and ultrasound; to block out noise and to bend light in various wavelengths, making objects invisible.

This research was an offshoot of superlens research at Duke's Pratt School of Engineering, the first group to demonstrate that metamaterials can act as cloaking devices.

The metamaterial lens would need to be tailored to each device, so the source and recipient would be tuned to each other, Urzhumov said. But this would be less annoying than having dozens of device-specific wires hanging around the house.

Dell XPS 15z review

Source: http://www.engadget.com/2011/05/23/dell-xps-15z-review/

For years, Dell's been teasing supermodel-thin laptops, each one flawed out of the gate: too pricey, too underpowered, and with underwhelming battery life. This time, Dell told us we'd get something different -- a laptop without compromise. Recently, Round Rock killed off the Adamo and nixed the XPS 14, and then rumors started to spin -- a spiritual successor would be the slimmest 15.6-inch notebook we'd ever seen, be crafted from "special materials" and yet cost less than $1,000. Dell even stated that it would have an "innovative new form factor" of some sort.

The company neglected to mention it would look like a MacBook Pro.

This is the Dell XPS 15z, and we're sorry to say it's not a thin-and-light -- it's actually a few hairs thicker than a 15-inch MacBook Pro, wider, and at 5.54 pounds, it weighs practically the same. It is, however, constructed of aluminum and magnesium alloy and carries some pretty peppy silicon inside, and the base model really does ring up at $999. That's a pretty low price to garner comparisons to Apple's flagship, and yet here we are. Has Dell set a new bar for the notebook PC market? Find out after the break.
