New Mars Rover Rolls For the First Time 100

Posted by Soulskill from the keep-them-doggies-rollin dept.
wooferhound writes "Like proud parents savoring their baby's very first steps, mission team members gathered in a gallery above a clean room at NASA's Jet Propulsion Laboratory to watch the Mars Curiosity rover roll for the first time. Engineers and technicians wore bunny suits while guiding Curiosity through its first steps, or more precisely, its first roll on the clean room floor. The rover moved forward and backward about 1 meter (3.3 feet). Mars Science Laboratory (aka Curiosity) is scheduled to launch in fall 2011 and land on the Red Planet in August 2012. Curiosity is the largest rover ever sent to Mars. It will carry 10 instruments that will help search an intriguing region of the Red Planet for two things: environments where life might have existed, and the capacity of those environments to preserve evidence of past life."

God bless the Can-Do attitude at MIT (and elsewhere, I suppose). I wish they hadn't thrown my application away, and hope that the totally-awesome-just-not-MIT school that I'm going to will support this kind of thing.

MIT Unveils First Solar Cells Printed On Paper 125

Posted by timothy from the let's-give-them-some-post-unveiing-privacy dept.
lucidkoan writes "MIT researchers recently unveiled the world's first thin-film solar cell printed on a sheet of paper. The panel was created using a process similar to that of an inkjet printer, producing semiconductor-coated paper imbued with carbon-based dyes that give the cells an efficiency of 1.5 to 2 percent. That's not incredibly efficient, but the convenience factor makes up for it. And in the future, researchers hope that the same process used in the paper solar cells could be used to print cells on metal foil or even plastic. If they're able to gear efficiencies up to scale, the development could revolutionize the production and installation of solar panels."

Spectrum of Light Captured From Distant World 32

Posted by Soulskill from the what-are-you-made-of dept.
An anonymous reader writes with this excerpt from Cosmos: "Astronomers have made the first direct capture of a spectrum of light from a planet outside the Solar System and are deciphering its composition. The light was snared from a giant planet that orbits a bright young star called HR 8799 about 130 light-years from Earth, said the European Southern Observatory (ESO). ... The find is important, because hidden within a light spectrum are clues about the relative amounts of different elements in the planet's atmosphere. 'The features observed in the spectrum are not compatible with current theoretical models,' said co-author Wolfgang Brandner. 'We need to take into account a more detailed description of the atmospheric dust clouds, or accept that the atmosphere has a different chemical composition from that previously assumed.' The result represents a milestone in the search for life elsewhere in the universe, said the ESO. Until now, astronomers have been able to get only an indirect light sample from an exoplanet, as worlds beyond our Solar System are called. They do this by measuring the spectrum of a star twice — while an orbiting exoplanet passes near to the front of it, and again while the planet is directly behind it. The planet's spectrum is thus calculated by subtracting one light sample from another."

Protecting At-Risk Cities From Rising Seas 243

Posted by Soulskill from the steal-moses'-superpowers dept.
Hugh Pickens writes "BBC reports that with about 10 million people in England and Wales living in flood risk areas, rising sea levels and more storms could mean that parts of at-risk cities will need to be surrendered to protect homes and businesses, and that 'radical thinking' is needed to develop sea defenses that can cope with the future threats. 'If we act now, we can adapt in such a way that will prevent mass disruption and allow coastal communities to continue to prosper,' says Ruth Reed, President of the Royal Institute of British Architects. 'But the key word is "now."' Changing sea levels is not a new phenomenon. In the Netherlands, for example, with 40% of its surface under sea level, water management and water defense have been practiced since time immemorial; creating mounds and dykes, windmills, canals with locks and sluices, the Delta Works and the Afsluitdijk, all to keep the water out. Similar solutions to protect British cities are based on three themes (PDF): moving 'critical infrastructure' and housing to safer ground, allowing the water into parts of the city; building city-wide sea defenses to ensure water does not enter the existing urban area; and extending the existing coastline and building out onto the water (using stilts, floating structures and/or land reclamation)."

Computers Key To Air France Crash 911

Posted by kdawson from the who-or-what-do-you-trust dept.
Michael_Curator writes "It's no secret that commercial airplanes are heavily computerized, but as the mystery of Air France Flight 447 unfolds, we need to come to grips with the fact that in many cases, airline pilots' hands are tied when it comes to responding effectively to an emergency situation. Boeing planes allow pilots to take over from computers during emergency situations, Airbus planes do not. It's not a design flaw — it's a philosophical divide. It's essentially a question of what do you trust most: a human being's ingenuity or a computer's infinitely faster access and reaction to information. It's not surprising that an American company errs on the side of individual freedom while a European company is more inclined to favor an approach that relies on systems. As passengers, we should have the right to ask whether we're putting our lives in the hands of a computer rather than the battle-tested pilot sitting up front, and we should have right to deplane if we don't like the answer."

imho. once you add an omnipotent, omniscient, etc being into the mix, you give up all hope of a rational explanation.

Such a being could have created the universe two seconds ago, and given us all memories, back stories, and slashdot. If he left signs, evidence, or hints, it was by choice. He is, after all, perfect. So to say that there isn't evidence for evolution, or that there IS evidence for creation, is totally irrelevant. We are interpreting what we see, and people who are better educated than most of us (on that subject) have come to a general consensus. So we chose to agree with them, or someone else, based (usually) on personal preference, not any first hand interpretation of evidence. So god put rocks (and other information) in the ground (and other, more biological places) that lead some (with no implication of majority or minority but myself included) to believe we evolved.

If you believe in god, it makes sense, since you believe he created everything: rocks, fossils, and our penchant for scientific discovery. If you believe the scientists, or were lucky enough to have data and methods to interpret yourself, then it makes sense because it follows a largely unbroken chain of reasoning. So you cannot fault someone for interpreting the evidence before them, because it is there. But the presence of evidence and prevailing theories should NOT BE A THREAT to those who have strong faith. After all, they are part of a perfectly designed creation, right?

I'm glad I got to weigh in on this issue.

Apple Rumored To Want To Buy Twitter 325

Posted by kdawson from the and-a-pony dept.
OSXGlitch writes "A post on TechCrunch this morning extends the rumor that Apple wants to buy Twitter with part of their massive cash reserve (estimated at nearly $29B). The Twitterverse is alive with speculation that the price being discussed is $700 million. This goes against reports that Twitter's founders aren't interested in selling, and that they estimate the value of the company at around $250 million. Two questions: How do we all feel about the possibility of Apple owning Twitter? And, can Twitter decline an offer that is nearly three times their estimated worth?"

Brain Decline Begins At Age 27 381

Posted by timothy from the mine-started-before-that dept.
krou writes "The BBC is reporting that a new study suggests that our mental abilities start to dwindle at 27 after peaking at 22, and 27 could be seen as the 'start of old age.' The seven-year study, by Professor Timothy Salthouse of the University of Virginia, looked at 2,000 healthy people aged 18-60, and used a number of mental agility tests already used to spot signs of dementia. 'The first age at which there was any marked decline was at 27 in tests of brain speed, reasoning and visual puzzle-solving ability. Things like memory stayed intact until the age of 37, on average, while abilities based on accumulated knowledge, such as performance on tests of vocabulary or general information, increased until the age of 60.'"
