100-Petabit Internet Backbone Coming Into View 137

lostinbrave notes laboratory work that could lead to long-haul network cables capable of exceeding 100 Petabits per second.kilometer. "Alcatel-Lucent said that scientists at Bell Labs have set an optical transmission record that could deliver data about 10 times faster than current undersea cables, resulting in speeds of more than 100 Petabits per second.kilometer. This translates to the equivalent of about 100 million Gigabits per second.kilometer, or sending about 400 DVDs per second over 7,000 kilometers, roughly the distance between Paris and Chicago. ... The transmissions were not just faster, they were accomplished over a network whose repeaters are 20 percent farther apart than commonly maintained in such networks, which could decrease the costs of deploying such a network."

LCROSS Team Changes Target Crater For Impact 39

Matt_dk sends word that NASA has chosen a new target crater into which to crash the Lunar Crater Observation and Sensing Satellite (LCROSS) mission vehicles. "The decision means that when NASA's LCROSS probe and its spent Centaur rocket stage slam into the moon on Oct. 9, they will crash into the large crater Cabeus, and not the nearby (and smaller) Cabeus A crater that was previously targeted. ... The data suggests the new target Cabeus has a concentration of hydrogen — an indication of possible water ice — that's higher than anywhere else at the lunar south pole. ... A small valley etched into the otherwise tall crater ridge of Cabeus should allow sunlight to shine on the ejecta cloud kicked up when LCROSS and its Centaur rocket stage crash into the moon in successive impacts."

The Duct Tape Programmer 551

theodp writes "Joel Spolsky sings the praises of The Duct Tape Programmer, who delivers programming teams from the evil of 'architecture astronauts' who might otherwise derail a project with their faddish programming craziness. The say-no-to-over-engineering attitude of the Duct Tape Programmer stems not from orneriness, but from the realization that even a 50%-good solution that people actually have solves more problems and survives longer than a 99% solution that nobody has because it's in your lab where you're endlessly polishing the damn thing. Like Steve Jobs, Duct Tape Programmers firmly believe that Real Artists Ship."

Alabama Wages War Against the Perfect Weed 360

pickens writes "Dan Berry writes in the NY Times that the State of Alabama is spending millions of dollars in federal stimulus money to combat Cogongrass, a.k.a. the perfect weed, the killer weed, and the weed from another continent. A weed that 'evokes those old science-fiction movies in which clueless citizens ignore reports of an alien invasion.' Cogongrass (Imperata cylindrica) is considered one of the 10 worst weeds in the world. 'It can take over fields and forests, ruining crops, destroying native plants, upsetting the ecosystem,' writes Berry. 'It is very difficult to kill. It burns extremely hot. And its serrated leaves and grainy composition mean that animals with even the most indiscriminate palates — goats, for example — say no thanks.' Alabama's overall strategy is to draw a line across the state at Highway 80 and eradicate everything north of it; then, in phases, to try to control it to the south. But the weed is so resilient that you can't kill it with one application of herbicide, you have to return several months later and do it again. 'People think this is just a grass,' says forester Stephen Pecot. 'They don't understand that cogongrass can replace an entire ecosystem.' Left unchecked, Pecot says 'it could spread all the way to Michigan.'"

How To Make Science Popular Again? 899

Ars Technica has an interesting look at the recent book Unscientific America: How Scientific Illiteracy Threatens Our Future, a collaboration between Chris Mooney, writer and author of The Republican War on Science, and scientist Sheril Kirshenbaum. While it seems the book's substance is somewhat lacking it raises an interesting point; how can science be better integrated with mainstream culture for greater understanding and acceptance? "We must all rally toward a single goal: without sacrificing the growth of knowledge or scientific innovation, we must invest in a sweeping project to make science relevant to the whole of America's citizenry. We recognize there are many heroes out there already toiling toward this end and launching promising initiatives, ranging from the Year of Science to the World Science Festival to ScienceDebate. But what we need — and currently lack — is the systematic acceptance of the idea that these actions are integral parts of the job description of scientists themselves. Not just their delegates, or surrogates, in the media or the classrooms."

Pigeon Turns Out To Be Faster Than S. African Net Screenshot-sm 406

inject_hotmail.com writes "The results are in: it's faster to send your data via an airborne carrier than it is through the pipes. As discussed Tuesday, a company in South Africa called Unlimited IT, frustrated by terribly slow Internet speeds, decided to prove their point by sending an actual homing pigeon with a "data card" strapped to its leg from one of their offices to another while at the same time uploading the same amount of data to the same destination via their ISPs data lines. The media outlet reporting this triumph said that it took the pigeon just over 1 hour to make the 80km/50mile flight, whereas it took over 2 hours to transfer just 4% of that data."

Additional Lab To Be Added To the ISS 81

Matt_dk writes "Apparently the International Space Station is going to get bigger. NASA and the Italian Space Agency (ASI) are preparing to sign an agreement to add another laboratory to the ISS by using a modified multipurpose logistics module (Raffaello) during the final Space Shuttle mission. It will be attached in September 2010 during Endeavour's STS-133 mission. The idea had originally been rejected, but earlier this year ISS program manager Michael Suffredini said using an MPLM for an additional module was being reconsidered."

Slow Oracle Merger Leads To Outflow of Sun Projects, Coders 409

An anonymous reader writes "Sun Microsystems might have had a chance if the Oracle merger had gone through quickly, but between the DoJ taking its time and the European Commission, which seems to get off on abusing American firms, just plain dragging its feet, that won't happen now. As Sun twists in the wind, unable to defend itself, and Oracle is unable to do anything until the deal closes, IBM is pretty much tearing Sun to shreds. By the time this deal closes, there won't be much left for Oracle. This is not how a Silicon Valley legend should end."

British Company Takes Lead To Stop Asteroids 198

An anonymous reader writes to tell us that following the news of NASA's budget cuts impacting their ability to do things like watch the sky for asteroids, a British company has decided to create a "gravity tractor" ship that could divert asteroids away from Earth if the need should arise. Of course, a gravity tractor certainly isn't a new idea. "Dr. Cordey said the company had worked with a number of space authorities on other methods of protecting the Earth from asteroids, but this one would be able to target a wider range. He said: 'We have done quite a lot of design work on this with the European Space Agency and we believe this would work just as well on a big solid iron asteroid as well as other types.' But the high cost implications mean that before the device could be made, it would have to be commissioned by a government or a group of governments working together."

DOJ Gives Oracle Approval To Buy Sun 162

k33l0r writes "The BBC is reporting that the US Justice Department has approved Oracle's takeover of Sun Microsystems. The acquisition gives Oracle control over (or a leading role in), among other things, Java, MySQL, (Open)Solaris, ZFS, OpenOffice, and the NetBeans IDE. 'The European Commission has still to rule on the deal, a step that will be required before it can close. That body has indicated it will issue an initial opinion on Sept. 3, according to the Wall Street Journal. It may OK the deal at that time or launch a four-month probe of it. ... The Justice Department ruling came earlier than expected, a possible response to Sun's declining revenues and precarious business position in a steep recession, as the required reviews proceeded.' We first discussed the deal back when it was announced in April."

BrainPort Lets the Blind "See" With Their Tongues 131

Hugh Pickens writes "Scientific American reports that a new device called 'BrainPort' aims to restore the experience of vision for the blind and visually impaired by relying on the nerves on the tongue's surface to send light signals to the brain. BrainPort collects visual data through a small digital video camera and converts the signal into electrical pulses sent to the tongue via a 'lollipop' that sits directly on the tongue, where densely packed nerves receive the incoming electrical signals. White pixels yield a strong electrical pulse and the electrodes spatially correlate with the pixels, so that if the camera detects light fixtures in the middle of a dark hallway, electrical stimulations will occur along the center of the tongue. Within 15 minutes of using the device, blind people can begin interpreting spatial information. 'At first, I was amazed at what the device could do,' says research director William Seiple. 'One guy started to cry when he saw his first letter.'" There is some indication that the signals from the tongue are processed by the visual cortex. The company developing the BrainPort will submit it to the FDA for approval later this month, and it could be on sale (for around $10,000) by the end of the year.

How To Prove Someone Is Female? 1091

krou writes "Caster Semenya won the 800m at the World Athletics Championship in blistering style, leaving her competitors in the dust, but she has been thrown into the midst of a scandal amidst claims that she's not really a woman. According to the many press reports, she's believed to shave, is flat chested, has a very masculine physique, previously preferred playing physical games with boys, and shunned traditional female activities and clothing. Questions about her gender have dogged her entire career. Previously, acceptance that she is a women relied on simple inspection of female genitals. But now the IAAF claim that they want to conduct further tests to see if 'she may have a rare medical condition that gives her an unfair advantage.' An IAAF spokesmen noted that 'The [testing] process was started after Semenya made her startling breakthroughs — a 25-second improvement at 1500m and eight seconds at 800m, just some weeks ago.' I'm curious what the Slashdot community thinks: what can be considered proof of someone being male or female? Is it simply a case of having the right genitals, or are there other criteria that should be used? Is the IAAF right in claiming that someone should be prevented from competing because they have a rare medical or genetic advantage?"

US Life Expectancy May Have Peaked 1053

Hugh Pickens writes "Live Science reports that although life expectancy in the United States has risen to an all-time high of 77.9 years in 2007 up from 77.7 in 2006, gains in life expectancy may be pretty much over, as some groups — particularly people in rural locations are already stagnating or slipping in contrast to all other industrialized nations. Hardest hit are regions in the Deep South, along the Mississippi River, in Appalachia and also the southern part of the Midwest reaching into Texas. The culprits — largely preventable with better diet and access to medical services — are diabetes, cancers and heart disease caused by smoking, high blood pressure and obesity. What the new analysis reveals is the reality of two Americas, one on par with most of Europe and parts of Asia, and another no different than a third-world nation with the United States placing 41st on the 2008 CIA World Factbook list, behind Bosnia but still edging out Albania. 'Beginning in the early 1980s and continuing through 1999 those who were already disadvantaged did not benefit from the gains in life expectancy experienced by the advantaged, and some became even worse off,' says a report published in PLoS Medicine by a team led by Harvard's Majid Ezzati, adding that 'study results are troubling because an oft-stated aim of the US health system is the improvement of the health of "all people, and especially those at greater risk of health disparities.'"

Up To 90 Percent of US Money Has Traces of Cocaine 441

mmmscience writes "Scientists have found that up to 90% of US paper money has some cocaine contamination, up from the 67% mark measured two years ago. Looking at bills from 17 cities, it's no surprise that the city with the highest level was Washington DC, where up to 95% of bills gathered there tested positive. From a global standpoint, both Canada and Brazil tested rather high (85% and 80%, respectively), but China and Japan were well behind the curve at 20% and 12%. The researchers hope that studies such as these will be of help to law enforcement agencies that are attempting to understand the growth and flow of drug use in communities."
