Household Robots Do Not Protect Users' Security And Privacy, Researchers Say

From Science Daily:

Science Daily (Oct. 9, 2009) — People are increasingly using household robots for chores, communication, entertainment and companionship. But safety and privacy risks of information-gathering objects that move around our homes are not yet adequately addressed, according to a new University of Washington study.

It's not a question of evil robots, but of robots that can be misused.

"A lot of attention has been paid to robots becoming more intelligent and turning evil," said co-author Tadayoshi Kohno, a UW assistant professor of computer science and engineering. "But there is a much greater and more near-term risk, and that's bad people who can use robots to do bad things."

Universe To End Sooner Than Previously Thought

Find The Entropy In This Super Massive Black Hole via Jevin Studios

From Popular Science:

While Robert Frost famously said that he prefers the world to end in fire, physicists have long predicted the universe will end with an icy sputter known as "heat death." Heat death occurs when the universe finally uses up all its energy, with all motion stopping and all the atoms in creation grinding to a halt. And, based on new calculations from a team of Australian physicists, it looks like heat death is far closer than previously thought.

The president of NRDC points to a growing investment by China in energy technologies.

China could beat the United States in a race to deploy clean energy technology that can reduce greenhouse-gas emissions, said Frances Beinecke, leader of a leading environmental group, speaking this week at MIT.

"I just got back from China, where there is tremendous investment in the clean tech sector," said Beinecke, the president of the Natural Resources Defense Council (NRDC). "They have a national renewable energy standard, a national efficiency standard, and China will build more of everything--more coal, more nuclear, more renewables--and they'll invest in more efficiency than any other single country in the world."

"The last time carbon dioxide levels were apparently as high as they are today — and were sustained at those levels — global temperatures were 5 to 10 degrees Fahrenheit higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland," said the paper's lead author, Aradhna Tripati, a UCLA assistant professor in the department of Earth and space sciences and the department of atmospheric and oceanic sciences.

In Test of Water on Moon, Craft Hits Bull’s-Eye -- New York Times

MOUNTAIN VIEW, Calif. — More than 230,000 miles from Earth, a NASA spacecraft hit a bull’s-eye on the Moon on Friday morning. Actually, two bull’s-eyes.

At 4:31 a.m. Pacific time (7:31 a.m. Eastern time), one piece of the Lunar Crater Observation and Sensing Satellite — LCROSS, for short — slammed into the bottom of a crater at 5,600 miles per hour, excavating about 350 metric tons of the moon and leaving behind a hole about 65 feet wide, 13 feet deep.

Trailing four minutes behind, instruments aboard the second piece analyzed the rising plume and sent its observations back to Earth before it also slammed into the same crater.

The Legacy Of America’s Largest Forest Fire

From The Smithsonian:

A 1910 wildfire that raged across three Western states helped advance the nation’s conservation efforts

Here now came the fire down from the Bitterroot Mountains and showered embers and forest shrapnel onto the town that was supposed to be protected by all those men with faraway accents and empty stomachs. For days, people had watched it from their gabled houses, from front porches and ash-covered streets, and there was some safety in the distance, some fascination even—See there, way up on the ridgeline, just candles flickering in the trees. But now it was on them, an element transformed from Out There to Here, and just as suddenly in their hair, on front lawns, snuffing out the life of a drunk on a hotel mattress, torching a veranda. The sky had been dark for some time on this Saturday in August of 1910, the town covered in a warm fog so opaque that the lights were turned on at three o’clock in the afternoon. People took stock of what to take, what to leave behind. A woman buried her sewing machine out back in a shallow grave. A pressman dug a hole for his trunk of family possessions, but before he could finish the fire caught him on the face, the arms, the neck.

From The L.A. Times:

The military takes the lead in brain trauma research, giving hope to wounded civilians of a 'silent epidemic.'

A world away from the roadside bombs and combat injuries of Iraq and Afghanistan, Americans are suffering the same type of brain injury seen in troops coming home from those war-torn countries. On American roads, at workplaces and on playing fields, more than 11 million have been hurt since the fighting overseas started.

Almost 1 in 5 of these civilians will struggle with lingering, often subtle symptoms -- headaches, dizziness, concentration difficulties and personality changes -- for a year, and often longer. As their memories falter, their work suffers and their relationships fray, many victims of brain trauma don't realize that their cognitive struggles are related to a blow to the head.

Fresh Impact Risks For Asteroid 'Poster Child'

Still heading our way (Image: Stocktrek Images/Getty)

From New Scientist:

The chances of the asteroid Apophis hitting Earth in 2036 are lower than we thought. But those worried about deep impacts should add a new entry to their calendar: 2068.

When Apophis was first spotted in 2004, the 250-metre-wide rock was briefly estimated to have a 2.7 per cent chance of hitting Earth in 2029. Further observations quickly showed that it will miss Earth that year – but should it pass through a 600-metre-wide "keyhole" in space, it will return to hit Earth in 2036.

Proposal Would Turn San Francisco Bridge Into A City

From Live Science:

San Francisco's Bay Bridge is being redone; a large portion of the bridge will remain unused, but in good shape. What can city planners do with this unique, unused space?

Science fiction writer William Gibson thought about the Bay Bridge in his 1993 novel Virtual Light:

"[Chevette] looked up, just as she whipped between the first of the slabs, and the bridge seemed to look down at her, its eyes all torches and neon. She'd seen pictures of what it had looked like, before, when they drove cars back and forth on it all day, but she'd never quite believed them. The bridge was what it was, and somehow always had been. Refuge, weirdness, where she slept, home to many and all their dreams."

Fossils Suggest An Ancient CO2-Climate Link

Mark Pink / Alamy

From Time Magazine:

Some of the best evidence linking rising carbon dioxide levels to a warmer world comes from the coldest places on earth. Samples of ancient air extracted from deep inside the Antarctic and Greenland ice caps make it clear that CO2 is scarce in the atmosphere during ice ages and relatively abundant during warmer interglacial periods — like the one we're in now.

The relationship between CO2 and climate is clear going back about 800,000 years. Before that, however, it gets murkier. That's largely because ice and air that old haven't yet been found. So scientists rely instead on indirect measurements — and these have led to a climate mystery: some episodes of past warming, including a planetary heat wave about 15 million years ago and another about 3.5 million years ago, seem to have happened without a rise in CO2. No one quite understands why. Maybe other greenhouse gases were the cause — methane, for example. Or maybe it had to do with changes in ocean circulation.
