Steve Jobs: 'we tried to buy a company called AdMob'

Source: http://www.engadget.com/2010/04/08/steve-jobs-we-tried-to-buy-a-company-called-admob/

Digg this! We'd previously heard rumors that Quattro Wireless was Apple's consolation prize after a deal with bigger mobile advertising rival AdMob fell through, and Steve Jobs confirmed it on no uncertain terms at the Q&A session following today's iPhone OS 4.0 event: "we tried to buy a company called AdMob... but Google snatched it away." Indeed they did, though that deal hasn't yet been approved by the Federal Trade Commission while Apple's already up, up and away with its iAd solution, so it seems like everything shook out for the best -- if you're an iPhone developer, anyway.

Just in case you prefer a slimmer profile to your television viewing experience without all that 3D nonsense, Mitsubishi has also refreshed its Unisen LCD HDTVs. All the new models have StreamTV a.k.a. VUDU Apps built in, plus playback from USB devices, and edge LED backlighting. While the LT-55154 drops a few speakers (if you brought your own), the step-up 164 line is sized from 40- to 55-inches including 16 speakers built in, integrated WiFi, Bluetooth streaming and more while the top of the line 265 models add two more speakers to the mix and upgrade to 240 Hz motion, an iPhone remote control app plus a few other configuration tweaks for the high end. Check after the break for prices (between $1,699 & $3,199) and more specs, though exact shipping information is still TBA.

MIT's Tiny Mechanical Muscles Could Power Tomorrow's Robotic Gizmos

The shape-memory alloy actuators might power minimally invasive surgical devices or tiny laptop cameras

Shape-memory alloys that change shape when heated could become tiny mechanical muscles for electronic devices. New mechanical devices based on the alloys produce three to six times more torque than electric motors, and weigh just one-20th as much.

Such devices, known as actuators, can be cut from a flat sheet of metal just a fraction of a millimeter thick. They emerged from a roject that aims to build printable robots, where the robots would consist of both the metal actuators and plastic components that could be built layer-by-layer through a process similar to inkjet printing.

The secret behind the lightweight actuators comes from rectangular notches carved into the metal alloy, which increases electrical resistance. That means only material around the notches heats up when an electrical current passes through.

Past actuators have made use of springs created from shape-memory alloys, including an iron shape-memory alloy that might lead to better surgical interventions and quake-proof buildings. But the MIT actuators can get rid of heat more quickly and consume less energy, because only a small part of the spring heats up when electrically charged,

The shape-memory actuators might eventually exert a force up to 160 times their own weight.

For now, the current actuators can already make use of their energy-sipping efficiency to run on batteries, and have helped create a wirelessly-controlled rolling robot that resembles a runaway tank tread. We're also excited to see more examples of creations such as the robo-bat.

Solving the Mystery of the Green LED For Pure, Efficient White Light

Source: http://www.popsci.com/science/article/2010-04/nrel-scientists-make-green-led-light-breakthrough-could-revolutionize-lighting

By deploying LED lighting across the board, the United States could save $120 billion – and untold tons of greenhouse gas emissions – over the next two decades. But it's another kind of green that's keeping the era of the LED from coming to fruition. While scientists have long been able to produce red and blue LED lights, the essential third ingredient for creating good, brilliant white light—green–has proven elusive. But researchers at the National Renewable Energy Laboratory have finally cracked the code on LED green.

By reverse engineering the solar cells they've worked on for so long, researchers at NREL were able to generate a difficult combination of green and red that could revolutionize the way we light our homes and other buildings. LEDs, after all, are the reverse of solar cells; one turns light into electricity, the other electricity into light.

Though the solar cells NREL scientists were working on hadn't gone so far as to capture green light–solar cells don't require green light to harvest energy–they had dabbled in the green spectral region. Years of tweaking the different lattice layers within solar cells informed their thinking: if they could closely manage the spectrum absorbed by solar cells by carefully tweaking the size and nature of the lattices within the cells, couldn't they do the same for LEDs?

So they did, achieving a deep green on their very first try by putting indium into gallium nitride. The team is now working to create a fourth color that will enhance white light even further. NREL envisions a deeper red blended with a lemony green that will be combined with a blue and a very deep green made from their indium-gallium nitride technology.

The resulting light would be highly manageable, giving the user the ability to electronically manipulate the hue. Meaning by the time the DOE phases out compact fluorescent bulbs in ten years, we should have a cheap, efficient and more flexible light source ready to take their places.

Mission Blue: filling in the blanks...

Source: http://feedproxy.google.com/~r/blogspot/MKuf/~3/ysuuxLXgfDI/mission-blue-filling-in-blanks.html

Last year, we launched Ocean in Google Earth, expanding the scope of Earth to include 3D maps of the world's oceans and videos, photos and narrative from the world's leading scientists and media sources to bring them to life. We worked with more than 100 partners to begin to fill in the "blue" part of the planet, adding hundreds of placemarks in more than 20 ocean layers. Since then, we've added hundreds of new posts to the Ocean layer with the help of Sylvia Earle's Mission Blue Foundation and dozens of committed individuals around the world. The posts come from a diverse range of partners including National Geographic, independent videographers and dive enthusiasts, government organizations like the National Oceanographic and Atmospheric Administration (NOAA) and international organizations like the International Union for Conservation of Nature (IUCN).

Today, the layer will become part of the default set of annotations seen by all Earth users. Although a humble step given the dearth of information available about these vast expanses of geography, we are happy to take one more step to make the oceans a first-class part of Google Earth and to give them at least a starter portion of the thick soup of photos and places that describe the land part of the planet. One of the greatest things about Earth is that it allows everyone to see and experience the fullness of their planet, from revisiting places they know well to venturing out to formerly unknown mountain peaks, desert vistas, and increasingly, the blue heart of life on Earth. As Sylvia has said of the Ocean on many occasions, "With knowing comes caring, and with caring there's hope."

Soon after last year's launch, Sylvia asked attendees at the TED conference to ! help her realize a wish: to create a series of marine protected areas she calls Hope Spots. Sylvia and a group of influential thinkers are now on a Mission Blue Voyage to the Galapagos Islands to brainstorm how they might best achieve better ocean protection. You can follow them on their journey by visiting the the Mission Blue Foundation website and on Twitter at @MissionBlue. There you can learn more about the launch of their Hope Spots initiative and visit all 18 of these spots using the Google Earth plugin.


We've also created a narrated tour featured in the Ocean Showcase to introduce you to eight of the regions proposed for protection: the Eastern Pacific Seascape including the Galapagos Islands, the Gulf of California, the Mesoamerican Reef in the Caribbean including Belize, the Sargasso Sea in the mid-Atlantic, the Chagos Archipelago in the Indian Ocean, the Coral Triangle, the Ross Sea in the Antarctic and Gakkel Ridge in the Arctic.

We'd also like to take a moment to thank the partners who have helped us improve our 3D canvas of the world's oceans in the past year: NOAA (global coverage), MBARI (Monterey Bay! Canyon) , The California State University at Monterey Bay (California Coast), The Center for Coastal and Ocean Mapping - Joint Hydrographic Center at the University of New Hampshire (Arctic) and The Living Oceans Society (British Columbia and Canada).

As Earth Day approaches, we hope you'll take a little time to explore the planet, including the blue part.
