Submission + - Nasal Spray Could Prevent Coronavirus Transmission (columbia.edu)

Snard writes: A nasal antiviral created by researchers at Columbia University Vagelos College of Physicians and Surgeons blocked transmission of SARS-CoV-2 in ferrets, suggesting the nasal spray also may prevent infection in people exposed to the new coronavirus.

The compound in the spray—a lipopeptide developed by Anne Moscona, MD, and Matteo Porotto, PhD, professors in the Department of Pediatrics and directors of the Center for Host-Pathogen Interaction—is designed to prevent the new coronavirus from entering host cells.

The antiviral lipopeptide is inexpensive to produce, has a long shelf life, and does not require refrigeration. These features make it stand out from other antiviral approaches under development, including monoclonal antibodies. The new nasal lipopeptide could be ideal for halting the spread of COVID in the United States and globally; the transportable and stable compound could be especially key in rural, low-income, and hard-to-reach populations.

Linux

Happy Birthday, Linus 376

Glyn Moody writes "Today is the birthday of Linus. Just under 19 years ago, on the first day the shops in Helsinki were open after the holidays, Linus rushed out and spent all his Christmas and birthday money on his first PC: a DX33 80386, with 4 Megs of RAM, no co-processor, and a 40 Megabyte hard disc. Today, the kernel he wrote on that system powers 90% of the fastest supercomputers, and is starting to find its way into more and more smartphones — not to mention everything in between. What would the world look like had he spent his money on something else?"

Open Source Could Have Saved Ontario Hundreds of Millions 294

Platinum Dragon writes "Ontario's auditor-general released a blistering report this week detailing how successive governments threw away a billion dollars developing an integrated electronic medical record system. This CBC article highlights an open source system developed at McMaster University that is already used by hundreds of doctors in Ontario. As one of the developers points out, 'we don't have very high-priced executives and consultants,' some of whom cost Ontario taxpayers $2,700 per day." The McMaster University researchers claim their system could be rolled out for two percent of the billion-dollars-plus already spent on the project. The report itself (PDF) also makes note of the excessive consultation spending: "By 2008, the Ministry’s eHealth Program Branch had fewer than 30 full-time employees but was engaging more than 300 consultants, a number of whom held senior management positions."

Microsoft Says No TCP/IP Patches For XP 759

CWmike writes "Microsoft says it won't patch Windows XP for a pair of bugs it quashed Sept. 8 in Vista, Windows Server 2003 and Windows Server 2008. The news adds Windows XP Service Pack 2 (SP2) and SP3 to the no-patch list that previously included only Windows 2000 Server SP4. 'We're talking about code that is 12 to 15 years old in its origin, so backporting that level of code is essentially not feasible,' said security program manager Adrian Stone during Microsoft's monthly post-patch Webcast, referring to Windows 2000 and XP. 'An update for Windows XP will not be made available,' Stone and fellow program manager Jerry Bryant said during the Q&A portion of the Webcast (transcript here). Last Tuesday, Microsoft said that it wouldn't be patching Windows 2000 because creating a fix was 'infeasible.'"

Generating Fast MD5 Collisions With ATI Video Cards 72

An anonymous reader writes "Yesterday at Black Hat USA 2009, a talk entitled MD5 Chosen-Prefix Collisions on GPUs (whitepaper) (Both PDFs) presented an implementation written in assembly language for ATI video cards that achieves 1.6 billion MD5 hash/sec, or 2.2 billion MD5 hash/sec with reversing, on an ATI Radeon HD 4850 X2. This is faster than the much-publicized 1.4-1.9 billion hash/sec figure that was supposedly reached on a PlayStation 3 by Nick Breese at Black Hat Europe 2008 (he later noticed an error in his benchmarking tool). Compared to the cluster of 215 PlayStation 3s that was used to create a rogue CA in December 2008, Marc Bevand claimed a cluster of 12 machines with 24 video cards would be a bit faster, consume 5 times less power, and be 10 times cheaper."

P2P Network Exposes Obama's Safehouse Location 307

Lucas123 writes "The location of the safe house used in times of emergency for the First Family was leaked on a LimeWire file-sharing network recently, a fact revealed today to members of the House Oversight and Government Reform Committee. Along with the safe house location, the LimeWire networks also disclosed presidential motorcade routes, as well as sensitive but unclassified document that listed details on every nuclear facility in the country. Now lawmakers are considering a bill to ban P2P use on government, contractor networks."

Sandia Studies Botnets In 1M OS Digital Petri Dish 161

Ponca City, We love you writes "The NY Times has the story of researchers at Sandia National Laboratories creating what is in effect a vast digital petri dish able to hold one million operating systems at once in an effort to study the behavior of botnets. Sandia scientist Ron Minnich, the inventor of LinuxBIOS, and his colleague Don Rudish have converted a Dell supercomputer to simulate a mini-Internet of one million computers. The researchers say they hope to be able to infect their digital petri dish with a botnet and then gather data on how the system behaves. 'When a forest is on fire you can fly over it, but with a cyber-attack you have no clear idea of what it looks like,' says Minnich. 'It's an extremely difficult task to get a global picture.' The Dell Thunderbird supercomputer, named MegaTux, has 4,480 Intel microprocessors running Linux virtual machines with Wine, making it possible to run 1 million copies of a Windows environment without paying licensing fees to Microsoft. MegaTux is an example of a new kind of computational science, in which computers are used to simulate scientific instruments that were once used in physical world laboratories. In the past, the researchers said, no one has tried to program a computer to simulate more than tens of thousands of operating systems."

Transparent Aluminum Is "New State of Matter" 406

Professor_Quail writes with this interesting excerpt: "Oxford scientists have created a transparent form of aluminum by bombarding the metal with the world's most powerful soft X-ray laser. 'Transparent aluminum' previously only existed in science fiction, featuring in the movie Star Trek IV, but the real material is an exotic new state of matter with implications for planetary science and nuclear fusion."

Unusual Physics Engine Game Ported To Linux 117

christian.einfeldt writes "Halloween has come early for Linux-loving gamers in the form of the scary Penumbra game trilogy, which has just recently been ported natively to GNU-Linux by the manufacturer, Frictional Games. The Penumbra games, named Overture, Black Plague and Requiem, are first-person survival horror and physics puzzle games which challenge the player to survive in a mine in Greenland which has been taken over by a monstrous infection/demon/cthulhu-esque thing. The graphics, sounds, and plot are all admirable in a scary sort of way. The protagonist is an ordinary human with no particular powers at all, who fumbles around in the dark mine fighting zombified dogs or fleeing from infected humans. But the game is remarkable for its physics engine — rather than just bump and acquire, the player must use the mouse to physically turn knobs and open doors; and the player can grab and throw pretty much anything in the environment. The physics engine drives objects to fly and fall exactly as one would expect. The porting of a game with such a deft physics engine natively to Linux might be one of the most noteworthy events for GNU-Linux gamers since the World of Goo Linux port."

Google's Chiller-Less Data Center 132

1sockchuck writes "Google has begun operating a data center in Belgium that has no chillers to support its cooling systems, which will improve energy efficiency but make weather forecasting a larger factor in its network management. With power use climbing, many data centers are using free cooling to reduce their reliance on power-hungry chillers. By foregoing chillers entirely, Google will need to reroute workloads if the weather in Belgium gets too warm. The facility also has its own water treatment plant so it doesn't need to use potable water from a local utility."

Embedded Linux Achieves One-Second Boot Time 164

Sam writes "A new goalpost has been set in the race for faster bootup times. MontaVista Software announced (and demonstrated at the Virtual Freescale Technology Forum) a dashboard application going from cold boot to operational in one second flat on their embedded Linux platform. Although this is unlikely to immediately benefit your average Linux user, previous real-time patches have eventually made their way into the main kernel."

US Postal Service Moves To GNU/Linux 477

twitter writes "The US Postal Service has moved its Cobol package tracking software to HP machines running GNU/Linux. 1,300 servers handle 40 million transactions a day and cost less than the last system, which was based on a Sun Solaris environment." The migration took a year. The USPS isn't spelling how big the savings are, except that they are "significant."

R.I.P. FTP 359

Strong Passwords Not As Good As You Think 553

Jamie noticed that Bruce Schneier wrote a piece on a paper on strong passwords that tells us that the old 'strong password' advice that many of us (myself included) regard as gospel might not be as true as we had hoped. They make things hard on users, but are useless against phishing and keyloggers. Everyone can change their password back to 'trustno1' now.
