Yesterday, in the intro to video number one of this two part extravaganza we wrote, "The effects of light and dark on adults' Circadian rythym has been studied over and over, but there hasn't been much research done on how light at night affects young children's sleep patterns."

Then we said, "This is the topic of Lameese Akacem's doctoral dissertation, and is a study being carried out under the aegis of the Sleep and Development Laboratory at the University of Colorado, Boulder," and we mentioned that this research is (at least in part) crowdfunded, and that the deadline for donating to this project is early next week, so if you feel this project is worth supporting you need to act within the next few days.

The effects of light and dark on adults' Circadian rythym has been studied over and over, but there hasn't been much research done on how light at night affects young children's sleep patterns. This is the topic of Lameese Akacem's doctoral dissertation, and is a study being carried out under the aegis of the Sleep and Development Laboratory at the University of Colorado, Boulder, under the direction of Assistant Professor Monique K. LeBourgeois. Aside from the inherent value of this research, which may help parents decide whether (and how much) they are messing up their children's sleep patterns by letting them view screens such as TVs, tablets or smart phones near bedtime, its funding is unique; the money for this study is coming, at least in part, from crowdfunding. The crowdfunding itself is an experiment. This study is one of a small, select group of projects the University of Colorado at Boulder has in its pilot crowdfunding program. Its crowdfunding time window closes next week, so if you want to help sponsor this experiment, and help learn how different kinds of light can affect how (and how well) small children sleep, you need to act within the next six days. (This is a two-part video. Part one runs today. Part two will run tomorrow.)

Presto Vivace points out this troubling new report from the Electronic Frontier Foundation: Recently, Verizon was caught tampering with its customer's web requests to inject a tracking super-cookie. Another network-tampering threat to user safety has come to light from other providers: email encryption downgrade attacks. In recent months, researchers have reported ISPs in the U.S. and Thailand intercepting their customers' data to strip a security flag — called STARTTLS — from email traffic. The STARTTLS flag is an essential security and privacy protection used by an email server to request encryption when talking to another server or client.

By stripping out this flag, these ISPs prevent the email servers from successfully encrypting their conversation, and by default the servers will proceed to send email unencrypted. Some firewalls, including Cisco's PIX/ASA firewall do this in order to monitor for spam originating from within their network and prevent it from being sent. Unfortunately, this causes collateral damage: the sending server will proceed to transmit plaintext email over the public Internet, where it is subject to eavesdropping and interception.

the agent man writes "The Hour of Code event taking place December 9-15 has produced a number of tutorials with the goal to excite 10 millions kids to code. It's really interesting to contrast the different pedagogical approaches behind the roughly 30 tutorials. The University of Colorado's 'Make a 3D Game' tutorial wants to excite kids to code by focusing less on coding. This pedagogy is based on the idea that coding alone, without non-coding creativity, has a hard time attracting kids who are skeptical of computer science, including a high percentage of girls who think 'programming is hard and boring.' Instead, the 'Make a 3D Game' activity has the kids create sharable 3D shapes and 3D worlds in their browsers, which they then want to bring to life — through coding. There is evidence that this strategy works. The article talks about the research exploring how kids get excited through game design, and how they can later leverage coding skills acquired to make science simulations. You can try the activity by yourself or with your kids, if you're curious."

An anonymous reader writes "Sky gazers at CU-Boulder's Fiske Planetarium are getting better, clearer and deeper views. And not just of astronomy anymore.

necro81 writes "Due to the ongoing shutdown of the U.S. Government, NASA is largely grounded. This is bad for all kinds of reasons, but one particularly bad outcome would have been missing the launch window for the MAVEN spacecraft, due to launch 18 November. The next launch window would not have been until 2016. MAVEN, thankfully, has been given the go-ahead, in large part because this orbiter will serve as a vital communications link for the Opportunity and Curiosity rovers currently on the surface. Currently, these rovers are served by two aging orbiters: Mars Odyssey (launched 2001) and Mars Reconnaissance Orbiter (launched 2005). Maintaining communications with the rovers is considered essential, hence the preparations and launch will proceed. (NASA's official mission website is currently offline.)"

Hugh Pickens DOT Com writes "Time Magazine reports that in and effort to involve non-rocket scientists in the next mission to the Red Planet, NASA invited the public in May to submit haiku, three line poems where 'the first and last lines must have exactly five syllables each and the middle line must have exactly seven syllables.' NASA promised to select five winners that will be adhered to the Mars Atmosphere and Volatile Evolution Mission (MAVEN) before it is launched towards Martian airspace. 'The Going to Mars campaign offers people worldwide a way to make a personal connection to space, space exploration, and science in general, and share in our excitement about the MAVEN mission,' said Stephanie Renfrow, lead for the MAVEN Education and Public Outreach program at CU/LASP. More than 15,000 entries were submitted by space geeks and poets the world over. A couple thousand were disqualified as too long, too short, or totally inappropriate, leaving about 12,500. The public voted online, and the five top vote-getters have been announced." The winner:

A University of Colorado-Boulder team has uncovered extremophile microbes in the rocky, high-altitude Atacama desert on the Chile-Argentina border "which seem to have a different way of converting energy than their cousins elsewhere in the world." According to the researchers, "[T]hese are very different than anything else that has been cultured. Genetically, they’re at least 5 percent different than anything else in the DNA database of 2.5 million sequences." It's an exciting frontier for biologists in part because of the recurring interest in the possibility that life has existed (or does exist) on Mars; the dry, volcanic Atacama is often compared to the Martian surface.

ananyo writes "Scientists have reported the first tabletop source of ultra-short, laser-like pulses of low energy, or 'soft,' X-rays. The light, capable of probing the structure and dynamics of molecules (abstract), was previously available only at large, billion-dollar national facilities such as synchrotrons or free-electron lasers, where competition for use of the equipment is fierce. The new device, by husband-and-wife team Margaret Murnane and Henry Kapteyn based at JILA in Boulder, Colorado, might soon lie within the grasp of a university laboratory budget — perhaps allowing them to one day be as common in labs as electron microscopes are."

the agent man writes "The idea of getting kids interested in programming in spite of their common perception of programming to be 'hard and boring' is an ongoing Slashdot discussion. With support of the National Science Foundation, the Scalable Game Design project has explored how to bring computer science education into the curriculum of middle and high schools for some time. The results are overwhelmingly positive, suggesting that game design is highly motivational across gender and ethnicity lines. The project is also finding new ways of tracking programming skills transferring from game design to STEM simulation building. This NPR story highlights an early and unplanned foray into bringing game-design based computer science education even to elementary schools."

An anonymous reader writes "Computer scientists at the University of Colorado and the Stevens Institute of Technology have shown that gamers that play with friends play better. The study used the blockbuster FPS Halo: Reach as a testbed, and combined ground truth data on friendships from an anonymous survey with data about the multiplayer competitions extracted using the Reach Stats API. They found that the more friends you have on your team, the more assists, the fewer betrayals, the more you score, and the greater the probability your team wins, and that this 'friends for the win' effect goes above and beyond the benefits of playing with skilled strangers. (They also show that older gamers are statistically better than younger players, contrary to popular opinion.) Study lead Prof. Aaron Clauset, writing on his blog, says that friends 'may be able to effectively anticipate or adapt to each others' actions or strategies without an explicit need for verbal (and thus time consuming) communication or coordination,' and 'these effects may be fairly universal, and not merely limited to the traditional domains like sports and war, where practicing together has a long tradition.'"

vikingpower writes "The Little Ice Age, lasting from the end of the Middle Age into the 17th century, may very likely have been caused by the combined effects of four major volcanic eruptions and increased sunlight reflection by increasing sea ice, the so-called Albedo effect. ... The University of Boulder has a press release with maps and photographs. Bette Otto-Bliesner, one of the scientists behind the 'volcano + sea ice' thesis, fields an earnest warning against drawing conclusions too quickly from this research: 'I think people might look at the Little Ice Age and think that all we need to save us from rising temperatures are some volcanic eruptions or the geo-engineering equivalent [...] But when you see what happened when global temperatures dropped by just one degree and you look at current predictions of six or seven degree increases for the future, you realize how precarious things are for life as we know it.'"

the agent man writes "Researchers at the University of Colorado at Boulder are exploring what it takes to systematically get programming back to public schools. They have created a game-design-based curriculum, called Scalable Game Design, using the AgentSheets computational thinking tool. Annual summer institutes train middle school teachers from around the USA to teach their students computational thinking through game design and computational science simulations. What's truly unique about this is that it is not an after-school program; it takes place during regular school courses. Entire school districts are participating with measurable impacts, increasing the participation of women in high school CS courses from 2% six years ago to 38-59% now. Educators would like to be able to ask students, 'Now that you can make Space Invaders, can you also make a science simulation?' To explore this difficult question of transfer, the researchers devised new mechanisms to compute computational thinking. They analyze every game submitted by students to extract computational thinking patterns and to see if students can transfer these skills to creating science simulations."

itwbennett writes "In a paper posted online this week, researchers from the University of Colorado at Boulder and McGill University outline three different types of attacks that could be launched against Chatroulette users. While the new research doesn't expose any gaping privacy holes, it does show how the service could be misused by determined criminals. For example, the researchers were able to use IP-mapping services to get a general idea of users' location (a public Web site, called Chatroulettemap.com already does this). Then by searching Facebook using information obtained in chats and comparing pictures, researchers were able to identify chatters. 'Even in a city as big as Chicago, you can drill down and find the person you're actually talking to,' said Richard Han, an associate professor with the University of Colorado who co-authored the paper."

An anonymous reader writes "A team of researchers have found that Comcast has quietly rolled out a new traffic-shaping method, which is interfering with web browsers in addition to p2p traffic. The smoking gun that documents this behavior are network traces collected from Comcast subscribers Internet connections. This evidence shows Comcast is forging packets and blocking connection attempts from web browsers. One has to hope this isn't the congestion management system they are touting as no longer targeting BitTorrent, which they are deploying in reaction to the recent FCC investigations."

Riding with Robots writes "Scientists have announced that they have used images from the robotic spacecraft Cassini to find moonlets embedded in Saturn's outer rings that are likely the remains of a larger moon that was shattered by an asteroid or comet.

An anonymous reader writes "A group of researchers have written a paper that lays out an attack against Tor (PDF) in enough detail to cause Roger Dingledine a fair amount of heartburn. The essential avenue of attack is that Tor doesn't verify claims of uptime or bandwidth, allowing an attacker to advertise more than it need deliver, and thus draw traffic. If the attacker controls the entry and exit node and has decent clocks, then the attacker can link these together and trace someone through the network."

Slashback tonight brings some corrections, clarifications, and updates to previous Slashdot stories, including a possible release date for the long awaited Optimus keyboard, yet another extension in the Blackberry court case, lakebed theory on Mars possibly all wet, US-CERT statistics perhaps not all they are cracked up to be, stem cell investigation reveals papers were faked, the FTC objects to the Netflix settlement, and a new Crossover Office fixes the WMF exploit among other things. Read on for details.

Optimus keyboard may have a real release date? Jacket writes to tell us that the much talked about Optimus keyboard has a suggestive message on their website. With "Good things come in small packages February 1, 2006" could it be possible that this holy grail (for some) keyboard could be available in our near future?

Yet another delay for Blackberry court case. ahsile writes "TheGlobeandMail.com is reporting that 'NTP Inc., the company suing Research in Motion Ltd over the Blackberry e-mail service, wants more time to respond to the U.S. Patent and Trademark Office's preliminary rejections of its patents.'

Lakebed theory on Mars all wet? Sensible Clod writes "The Meridiani Planum region on Mars, long believed to have been covered with water millions of years ago, may not have been so wet after all, according to a new study from the University of Colorado at Boulder. From the article: 'The new study indicates chemical signatures in the bedrock, interpreted...as evidence for widespread, intermittent water at Mars' surface, may have instead been created by the reaction of sulfur-bearing steam vapors moving up through volcanic ash deposits. Known as Meridiani Planum, the region may have been more geologically similar to volcanic regions in parts of North America, Hawaii or Europe.'"

US-CERT statistics not all they are cracked up to be? jtshaw writes "Tectonic has an interesting article about the latest US-CERT stats. The actual vulnerabilities for a hand full of OS's after wading through the data: Microsoft Windows - 44, Apple Mac OS X - 21, IBM AIX - 21, HP-UX - 15, SCO Unix - 9, Red Hat Linux - 7, Suse Linux - 12, Debian Linux - 10, Gentoo Linux - 5, FreeBSD - 13, NetBSD - 2. It appears to me that commercial unix systems and open source *nix systems did pretty well compared to Windows on the vulnerability front."

Stem cell papers, confirmed fakes. An anonymous reader writes "The committee created to investigate stem cell researcher Hwang Woo Suk has confirmed that his first and second papers were faked. 'dashing hopes that his work is a breakthrough in treatments for diabetes and Parkinson's disease. [...] The panel backed Hwang's claim that he cloned the world's first dog.'"

FTC objects to Netflix settlement. AtariDatacenter writes "Although some question the validity of a recent lawsuit against Netflix, many users were up in arms about the terms of the settlement, which seemed like more of a marketing gimmick. Today, we learned that The Federal Trade Commission agreed, and asked the judge to reject the terms of the settlement."

New Crossover Office fixes,among other things, WMF exploit. ubuntuincleelum writes "Just on the heels of the announcement of new WMF security vulnerabilities Codeweavers is releasing Crossover Office 5.0.1. A bugfix release, this release features a fix for the original WMF bug. Among the changes in this release: Improved support for Gnome, improvements in Debian packaging and improvements in general for operability on Debian and Debian Derivatives."

It doesn't come easy writes "NASA's Institute for Advanced Concepts has chosen a proposal by the University of Colorado (UC) at Boulder to image distant planets around other stars for a second round of funding. Known as the New Worlds Observer, the UC project is for an orbiting, soccer-field sized "starshade" shaped like a daisy that would funnel light from distant planets between its petals to a second spacecraft trailing 50,000 miles behind. If the concept proves feasible, it could 'identify planetary features like oceans, continents, polar caps and cloud banks, and even detect biomarkers like methane, water, oxygen and ozone [...]'"

kakos writes "At the Tokyo Game Show, Nintendo president Satoru Iwata has revealed what the Nintendo Revolution controller looks like. The new controller is a radical departure from traditional controller types. Has Nintendo struck gold with their new controller design? The reviewers seem to think so. It should be interesting to see how gamers react to Nintendo's new innovation."

Ant writes "Wired News report that the dead and the desperate of New Orleans now join the farmers of Aceh and the fishermen of Trincomalee, villagers in Iran and the slum dwellers of Haiti in a world being dealt ever more punishing blows by natural disasters... ... "We rely on technology and we end up thinking as human beings that we're totally safe, and we're not," said Miletti, of the University of Colorado. "The bottom line is we have a very unsafe planet." By one critical measure, the impact on populations, statistics show the planet to be increasingly unsafe. More than 2.5 billion people were affected by floods, earthquakes, hurricanes and other natural disasters between 1994 and 2003, a 60 percent increase over the previous two 10-year periods, U.N. officials reported at a conference on disaster prevention in January. Those numbers don't include millions displaced by last December 2004's tsunami, which killed an estimated 180,000 people as its monstrous waves swept over coastlines from Indonesia's Aceh province to Trincomalee, Sri Lanka, and beyond. By another measure -- property damage -- 2004 was the costliest year on record for global insurers, who paid out more than $40 billion on natural disasters, reports German insurance giant Munich Re. Florida's quartet of 2004 hurricanes was the big factor. But generally it's not that more "events" are happening, rather that more people are in the way, said Thomas Loster, a Munich Re expert. "More and more people are being hit," he said..." I'd also like to point out a project here to find housing for Katrina's victims; it tries to combine lists of sites offering housing, and do a meta-search.

Cr0w T. Trollbot asks: "It looks like New Orleans is going through something very close to the worst case scenario right now. This somewhat prescient study, written well before the hurricane, describes some of the challenges (engineering and otherwise) facing New Orleans. 'In this hypothetical storm scenario, it is estimated that it would take nine weeks to pump the water out of the city, and only then could assessments begin to determine what buildings were habitable or salvageable. Sewer, water, and the extensive forced drainage pumping systems would be damaged. National authorities would be scrambling to build tent cities to house the hundreds of thousands of refugees unable to return to their homes and without other relocation options.' The hypothetical is looking awful close to reality right now. What can be done about draining and rebuilding New Orleans in light of the massive flooding, and what can be done to prevent and/or lessen such disasters in the future?"

mathinator writes "A study by researchers at the University of Waterloo indicates that Earth in its infancy probably had substantial quantities of hydrogen in its atmosphere, a surprising finding that may alter the way many scientists think about how life began on the planet. The new study indicates that up to 40 percent of the early atmosphere was hydrogen, implying a more favourable climate for the production of pre-biotic organic compounds like amino acids, and ultimately, life. The paper was authored by doctoral student Feng Tian, Prof. Owen Toon and Research Associate Alexander Pavlov of CU-Boulder's Laboratory for Atmospheric and Space Physics, and by Prof. Hans De Sterk of University of Waterloo's Applied Mathematics department. The paper was published in the April 7 issue of Science Express, the online edition of Science Magazine"

MattHaffner writes "Yesterday, a status report from the Far Ultraviolet Spectroscopic Explorer (FUSE) operations center reports that the satellite is in 'safe mode' after losing (another) reaction wheel--the mechanisms used to point the spacecraft. FUSE had been operating with only two of three original wheels for about two years using a creative solution utilizing the earth's magnetic field. Losing a second wheel for good may mean a serious reduction in science, however. For those keeping track, this is the third major blow to UV astronomy in less than a year. The Cosmic Origins Spectrograph (COS) was due to be installed on the canceled SM4, and the Space Telescope Imaging Spectrograph (STIS), a major instrument on HST, failed in 2004 Aug. The infrared is well covered by current and upcoming NASA missions including the Spitzer Space Telescope, the James Webb Space Telescope (JWST), and SOFIA, but ultraviolet astronomy may have a serious dearth of instruments in the near future. While IR is useful for studying dusty environments, star formation, planetary system formation, and red-shifted galaxies, the UV is the best place to study the chemical composition and evolution of interstellar gas, stars, and galaxies since many of the more abundant elements have strong spectral signatures in that region of the spectrum."

edpin writes "University of Colorado at Boulder students hacked the 30,000-plus-member Internet Chess Club as part of research funded by the National Science Foundation. With guidance from University of Colorado at Boulder computer security researcher John Black, two students reverse-engineered the service to up their ranks and steal passwords." Update: 10/10 23:05 GMT by T : Reader Bryan Rapp points out that this story duplicates the one posted last month -- sorry about that.

Scott_F writes "Researchers at the University of Colorado at Boulder have been able to defeat the security mechanisms of the Internet Chess Club and can effectively play a zero-time match, as well as have complete control over the game. The paper is titled How to Cheat at Chess: A Security Analysis of the Internet Chess Club. If you're not familiar with the ICC, it is where many Grandmasters play regularly, with rumors of Bobby Fischer making an occasional appearance. It appears that the ICC has relied on security through obscurity, but we all know how poorly that works. Chess, anyone?" Update: 09/08 21:08 GMT by J : In totally unrelated chess news, I found today's commentary on Zermelo's Theorem interesting, both for the math of the game and the look at a mistaken echo chamber.

bitkid writes "I recently run across techniques that can be used to watermark program code. While I yet have to see some source code for this to play with, the authors claim that the watermarks can be introduced into the source code and can be found in the compiled executable. My question for the slashdot-crowd is: Do you think free software (GPL or other viral licenses) should be watermarked? This could help to find GPL violations (think Everybuddy or Linksys) or can be used in court someday against the next SCO to prove authorship. What might be the ramifications of this?"

Watching these variables can give administrators advance warning about potential problems with the server. We are currently using an in-house solution written in Perl but its age is showing. I have found plenty of proprietary solutions such as HP OpenView and Sun Management Center, but these cost thousands of dollars. What solutions do Slashdot readers use? Are there any powerful open source solutions that I'm missing? Is anyone else running homegrown software that they are happy with? We are running an entirely Solaris environment but I am interested in any UNIX solution."

TheMatt writes "As reported on PhysicsWeb and published in Science (subscription required), researchers at AIST and co-workers believe they have found evidence of magnetic monopoles. They observed an anomalous Hall effect in a ferromagnetic crystal that they say can only be explained via magnetic monopoles. To refresh your memory, magnetic monopoles are the magnetic analogue of electrons and other charged particles--a "north" or "south" pole only. Dirac in 1931 showed that the existence of a magnetic monopole naturally leads to the quantization of electric and magnetic charge. Thus, showing the existence of just one magnetic monopole would be quite profound for physics, but their mass (> 10^16 GeV) has made searches for them difficult."

core plexus writes "The Anchorage Daily News is reporting that in late May, researchers reported finding that the shuttle's exhaust, 97 percent of which is water vapor, quickly migrates to the highest reaches of the atmosphere above the Arctic. There the vapor spreads out about 50 miles high in Earth's mesosphere, just below the thermosphere, the air's highest layer, and settles to form a wispy type of cloud called noctilucent clouds. The shuttle trails a giant plume of exhaust while rising through the atmosphere, Mike Stevens, the study's lead author, said earlier this summer on Arctic Science Journeys Radio at the University of Alaska Fairbanks. "You can think of it as essentially a long garden hose that is on the order of (621 miles) long," Stevens said."

TheMatt writes "The US Supreme Court today has upheld CIPA, the law that required public schools and libraries to put internet filters on computers or lose federal funding. Quote: 'The court in a 5-4 decision ruled that the Children's Internet Protection Act does not violate the First Amendment, but that filters sometimes, do block informational Web sites.'" The decision will be posted on the US Supreme Court website later today. The case is United States v. American Library Association, 02-361. We had covered this story before.

TheMatt writes "As reported by PhysicsWeb, physicists are proposing a "futuristic but not necessarily impossible" method of destroying nuclear weapons via high-energy neutrinos sent through the earth. Based on current planned efforts, this 'vast extrapolation' of current technology would use 1000 TeV beams. This would require a 1000-km diameter storage ring using magnets orders-of-magnitude stronger than currently available. The cost would be around $100 million-plus and it'd use 50 GW of energy, the UK's current consumption. (And the slight problem that the process might set off the nukes, instead of just melting them...)"

TheMatt writes "An article at the IHT describes an effort to make Paris one big Wi-Fi hotspot. The project, with partners like RATP and Cisco, if approved, will place two or three antennae outside each of the 372 Metro stations in Paris and link them through an existing fiber network that runs through the subway tunnels. The current pilot project is centered along the route of Bus No. 38. You can sign up for access to the pilot which is free until June 30."

TheMatt writes "Nature Science Update is reporting today about research by New Zealand scientists on redesigning how the "Back" button works in your browser. They point to the fact that the current "Back" is more of an "Up" in a stack of pages. They propose a system that records all pages visited. A good summary page of their efforts in web navigation (including a interesting thumbnail-style "Back" menu) can be found on their page."

Ahotasu writes "Over at SpaceFlightNow, there is a short NASA news release discussing the development of and first emergency use of a production parachute system for a general aviation aircraft. Whole-ultralight parachute systems have been available and used for some time, but this is apparently the first use in a "certified general-aviation aircraft". From the article: "In October 2002, a pilot released his single engine aircraft's parachute and landed safely in a Texas mesquite- tree grove. The pilot was uninjured, and there was minimal damage to the plane. The safe landing made aviation history, as it was the first emergency application of an airframe parachute on a certified aircraft." Here's the company's website. Looks like right now, they only have models for a select few gen. aviation aircraft, probably the most popular models."

bgitac writes "CalTech has provided an online course on gravity waves by Kip Thorne. The course is described as "an introduction to all major aspects of gravitational waves." Prerequisites for this course are an understanding of classical mechanics. Weekly exercises and solutions as well as DVD quality videos of lectures are provided. The first couple lectures actually seem to be somewhat comprehendable!"

screenbert writes: "A new and novel way of communicating over fiber optics is being developed by physicists supported by the Office of Naval Research. Rather than using the amplitude and frequency of electromagnetic waves, they're using the polarization of the wave to carry the signal. Such a method offers a novel and elegant method of secure communication over fiber optic lines. This press release has more information. Of course I always thought that fiber was always pretty secure anyway since it's a lot harder to tap than copper."
