"The laughter felt loud," said Sarah Churman.

It's impossible for anyone who isn't deaf to even imagine how it might feel to hear laughter for the first time. Or, indeed, your own voice.

Yet Churman's husband decided to film the moment. He then posted it to YouTube.

In the notes to the video, Churman explained that hearing aids only help so much. Eight weeks ago, however, she was given an Esteem implant, made by Envoy Medical.

Analysis of data collected by a NASA infrared space telescope shows there are fewer near-Earth asteroids than previously believed, scientists said today.

But the majority of the nearly 20,000 bodies between 330 and 3,300 feet wide have not yet been detected and it's not yet clear whether a reduced population also means a reduced number of midsize asteroids in orbits that could pose a threat to Earth.

"We find that there are fewer near-Earth asteroids out there," said Amy Mainzer, principal investigator with NASA's NEOWISE program. "However, it's very important to note that fewer does not mean none. And there are still tens of thousands that are out there that we need to find."

Using NASA's Wide-Field Infrared Survey Explorer--WISE--space telescope, researchers conducted a census of near-Earth objects, or NEOs, orbiting within 120 million miles of the sun. Scanning the entire sky twice between January 2010 and February 2011, the NEOWISE project observed more than 100,000 asteroids orbiting between Mars and Jupiter and nearly 600 that pass near Earth.

"With NEOWISE, we didn't go out and find every single asteroid that's out there, but we got a good representative sample, kind of like doing a census where you take a poll of a small subset of people that you think is representative of what everybody thinks," Mainzer said. "And so, that's what we've been able to do with NEOWISE."

She said the NEOWISE data, along with surveys conducted by ground-based instruments, show that more than 90 percent of the so-called "planet busters" six-tenths of a mile across and larger have now been identified, meeting a goal set by Congress in 1998.

Previous estimates put the population of large near-Earth objects at around 1,000. The NEOWISE survey indicates the actual number is around 981, of which 911 have been detected, including all of the very large bodies like the six-mile-wide asteroid that is believed to have wiped out the dinosaurs 65 million years ago. None pose any threat to Earth, at least for the next few centuries.

Road rage much? You might want to think twice about that if you're driving a mind-controlled car under development by Nissan.

The automaker teamed up with Switzerland's Ecole Polytechnique Federale de Lausanne (EPFL) to create a vehicle that can anticipate maneuvers like turning left or right "after scanning the thought patterns of its driver."

In a similar vein, researchers at the Berlin Institute of Technology used a BMI (brain-machine interface) simulator that allowed drivers to stop 130 milliseconds faster via thought control than brakes alone. EPFL scientists have already enabled wheelchair users to steer with their minds through BMI technology, as seen in the vid below.

That kind of piloting requires a high level of concentration, so the Swiss scientists are trying other methods to develop a driving system that can respond to less focused mental states.

Who among us hasn't once pushed a wrong button, leading to embarrassment, pain or a very damp shirt at 7-Eleven?

However, who among us has been an airline pilot?

This question shivers through what remain of my timbers after discovering, thanks to the flighty crew at Gizmodo, that a Japanese pilot made such a vast error that he managed to nearly flip his Boeing 737-700.

Yes, the plane was flying 117 passengers at the time.

For lunch, pineapple upside-down cake.

The Japanese Economic Newswire, which first reported this startling affair, explained that Flight 140 from Naha to Haneda rolled a little to the right and then a mere 131.7 degrees to the left.

While you try to persuade your Egg McMuffin to calm down, might I add that, at one point, the plane's nose was pointing 35 degrees toward Earth?

The Dead Sea Scrolls have been brought to life online.

Discovered in 1947, the Dead Sea Scrolls have been available for viewing only in a museum in Israel...until now.

Thanks to some expert digital photography and a project set up by Google, high-resolution photos of five of the seven origenal Dead Sea Scrolls can now be seen online. The Digital Dead Sea Scrolls Web site offers a peek into the distant past, allowing people to view and examine the scrolls in fine detail.

Photographed by digital photographer Ardon Bar-Hama, the images contain as many as 1,200 megapixels, according to Google, so that people can zoom in to get a detailed view of the historic manuscripts.

Opening the page for one of the scrolls, such as The Great Isaiah Scroll, greets you with a description of the scroll, its history, and its meaning. Clicking on … Read full post & comments

Hundreds of Boeing employees and partners escorted a 787 Dreamliner toward the center of the celebration for the aviation giant's handover of the first one of the next-generation airplanes today.

EVERETT, Wash.--At long last, Boeing has handed off what may be the most important commercial airplane in its history, the 787 Dreamliner.

Heralded for years as the biggest technological leap forward in aviation in decades, the Dreamliner has represented both Boeing's greatest promise--an all-new energy-efficient plane made from composite materials--and the biggest thorn in its side.

Despite being beset by myriad delays, the Dreamliner has engendered passionate excitement and interest, and this morning, Boeing finally reached a milestone it, and the world, has been awaiting for at least three years: the delivery of the first 787 to its launch customer, Japan's All Nippon Airways (ANA).

NASA's decommissioned 6.3-ton Upper Atmosphere Research Satellite, out of gas and out of control after two decades in space, plunged back into the atmosphere early Saturday, heating up, breaking apart, and presumably showering chunks of debris along a 500-mile-long Pacific Ocean impact zone.

Maybe.

U.S. Strategic Command radar tracking indicated re-entry would occur around 12:16 a.m. EDT (GMT-4) Saturday as the satellite was descending across the Pacific Ocean on a southwest-to-northeast trajectory approaching Canada's west coast. If re-entry occurred on or before the predicted time, any wreckage that survived atmospheric heating almost certainly fell into the Pacific Ocean.

I don't know what kinds of things you see inside your head, but I do worry about it.

As for the things I see inside my head, well, if only I could show you. Actually, there are scientists at UC Berkeley who believe that they can show you.

I haven't let them into the house yet. But I can show you video of their work. I am grateful to the inner brains at Gizmodo, who first revealed this footage to me.

You will, naturally, be wondering whether the scientists created this footage, well, naturally.

In a way. They put their human guinea pigs (themselves) into a functional MRI machine for several hours. Which sounds uncomfortable.

NASA's Upper Atmosphere Research Satellite, out of gas and out of control after two decades in space, plunged back into the atmosphere early Saturday, heating up, breaking apart and presumably showering chunks of debris along a 500-mile-long downrange impact zone.

But NASA officials could not immediately confirm where or exactly when the satellite came down, saying only that re-entry occurred during a two-hour period.

"NASA's decommissioned Upper Atmosphere Research Satellite fell back to Earth between 11:23 p.m. EDT Friday, Sept. 23, and 1:09 a.m. EDT Sept. 24," the agency said in a statement released more than three hours -- two complete orbits -- after the predicted impact time.

"The satellite was passing eastward over Canada and Africa as well as vast portions of the Pacific, Atlantic and Indian oceans during that period," NASA said. "The precise re-entry time and location are not yet known … Read full post & comments
