A Simple Grid Computing Synchronization Solution
atari_kid writes "NewScientist.com is running a article about a simple solution to the synchronization problems involved in distributed computing. Gyorgy Korniss and his colleagues at the Rensselaer Polytechnic Institute proposed that each computer in a grid synchronize by occasionally checking with a randomly chosen computer in the network instead of centralizing the grid by having a global supervisor." -
Steam Powered Underwater Jet Engine
Bob Vila's Hammer writes "An Australian engineer, Alan Burns invented a very efficient underwater steam powered jet engine. "Steam that is produced from a petrol or gasoline fueled boiler emerges at high speed from a rearward-facing ring-shaped nozzle into a cone-shaped chamber. Shock waves created as the steam condenses are focused by the chamber to blast water out of the back. Besides powering watercraft pretty efficiently, it can also be used as an extremely robust pump. Pretty Cool." -
Transplanting A Nut Allergy
Gavinsblog writes "New Scientist is reporting that a man who received a liver transplant from a donor who died of anaphylactic shock, went on to develop a life-threatening nut allergy himself. The man had no history of a nut allergy suffered an anaphylactic reaction to a cashew nut 25 days after receiving the liver. Should the liver have read 'Warning: may contain traces of nut'?" -
South Pole to Get Highway
tetrad writes "The New Scientist magazine reports that the US is building a road to the South Pole. The "highway" would cross the Ross Ice Shelf and then pass through the Transantarctic Mountains (map here). Convoys of tractors will be the only traffic on the road, bringing fuel and heavy equipment to the South Pole, as well as enabling the installation of a $250M fibre-optic communications cable (discussed previously)." -
Produce Organs...From Printer
Gavinsblog writes "New Scientist reports that researchers have modified desktop printers and filled them with suspensions of cells instead of ink. Apparently the work is a first step towards printing complex tissues or even entire organs. Amazing technology. " Well, I guess this could give a whole new meaning to "watermarking". -
Electromagnetic Ship Docking System Debuts
Makarand writes "A system that uses electromagnets for docking ships is getting ready to be tested at a port in the Netherlands according to this article in the New Scientist. Magnetic docking systems were never used in the past as magnetic fields posed dangers to sensitive cargo like TVs and monitors. Researchers at the Delft University of Technology have developed electromagnets whose magnetic fields do not penetrate far into the ship for this special application. The magnets can be periodically switched off and on rapidly to allow ships to rise and fall with the tide." -
Banana to be Sequenced
GodsMadClown writes "New Scientist reports that a global consortium plans to sequence the genetic code of a wild banana from east Asia. Because bananas are triploidal instead of diploidal, they are only able to reproduce asexually, which means that it adapts slower than organisms reproducing sexually. 'One rule of joining the consortium is that any invention developed through the project and protected [by patent] will be made available to smallholders through a royalty-free license,' says Emile Frison, director of the International Network for the Improvement of Banana and Plantain." -
China Blocks Bloggers' Sites
JollyGoodChase writes "Not only are some some sites blocked in China, but according to NewScientist.com so are blogs. One anonymous Chinese blogger on a US site on Sunday: 'I know that a lot of Chinese people have blogs and that they will not be pleased to see their personal journals taken away for unknown political reasons.'" -
Fifty Year Old Moon Mystery Explained
ekarjala writes "This article from NewScientist.com explains that a "flash" on the moon's surface that (captured by an amateur photographer 50 years ago) was probably the result of a 20 meter asteroid hitting the moon's surface." -

More 3D Printer News
tallackn writes "The New Scientist website has an article that tells of a 3D gadget printer which will allow fully assembled electric and electronic gadgets to be printed in one go. 'The trick is to print layer upon layer of conducting and semiconducting polymers in such a way that the circuitry the device requires is built up as part of the bodywork.' When the technique is perfected, devices such as light bulbs, radios, remote controls, mobile phones and toys will be spat out as individual fully functional systems without expensive and labour-intensive production on an assembly line." -

The Speed Of Gravity Revealed
redwolfoz writes "New Scientist is reporting that the speed of gravity has been measured for the first time. 'The landmark experiment shows that it travels at the speed of light, meaning that Einstein's general theory of relativity has passed another test with flying colours.' Researchers made the measurement of the fundamental physical constant with the help of the planet Jupiter. One important consequence of the result is that it will help constrain the number of possible dimensions in the Universe." -

Habitable Planets May Be Common
swight1701 writes "New Scientist tells us, "one in four of the planetary systems identified to date outside the Solar System are capable of harbouring other Earths, say astrophysicists, a much higher proportion than anyone expected." Two seperate groups have come up with results that line up with each other, the latest one using simulations of 85 systems. Warm up the warp engines, time to go planet hopping!" -
Lab-Grown Steak
swight1701 writes "New Scientist has an article about several researches who are trying to perfect growing seafood, chicken and beef in the lab without the animal. NASA started the program by wanting to provide burgers for Mars astronauts, and researchers hope to look to McDonalds, et al as funding sources in the future. The biggest problems being nutrient delivery to thick meat and exercise for the sedentary slabs. Processed meats seem to be something that may be a reality soon, while your animal friendly filet mignon may take a little while." -
The Year in Technology
bedessen writes "It's that time again, when we look back on the year in summary. New Scientist has an article "2002, The Year in Technology", as well as "The Year in Medicine and Biology." Popular Science brings us "The 15th Annual Best of What's New."" -

Melting Away Ice Hazards
RadioheadKid writes "Dartmouth College Professor Victor F. Petrenko is getting a grip on ice. He and his colleagues have found ways to take advantage of the "protonic" semiconductor properties of frozen water. They see many applications of this discovery from melting ice on power lines to electronic speed control for skis and snowboards. I guess those Petrenkos just love the ice." -
Out-of-Body Treatment For Liver Cancer
Tangential writes "This is amazing. Liver cancer, dangerous to treat and often deadly. Dosing that part of your body with enough radiation to cure the cancer often does as much harm as good. If they could just remove your liver, send it down to the lab to be treated and put it back in. An Italian MD has done just that." There's a story at New Scientist as well. -
Scientists Don't Read the Papers They Cite
WatertonMan writes "Very interesting and sure to be controversial study that suggests most scientists don't read the papers they cite. This means that if one paper misreads a work the misreading propagates. It's a very interesting study and has big implications for science, in my opinion. New Scientist has a good overview of the work. Given that most attention to work has been in sloppy work on the experimental side (poor methadology or outright fraud) this suggests a whole other problem. A lot of the ultimate problem is that many in research are concerned more about publishing than in solving the issues they investigate. Ideally the point both in science and in academics in general is to understand the ideas. Yet those of you who've looked up footnotes realize that actually engaging the ideas of other researchers typically falls by the wayside. Often footnotes are there simply because references are needed. Engaging others works is secondary. I've always thought that the hard sciences were more immune to that effect than the humanities. I guess not." -

Chemotherapy Patients Set Off Subway Alarms
dave writes "Recently, cities such as New York and elsewhere have been installing radiation detectors in subways as an anti-terror precaution. However, as reported in New Scientist, patients who are undergoing radiation treatment are setting off the alarms. From the article, "a 34-year-old patient who had been treated with radioactive iodine for Graves disease, a thyroid disorder, returned to their clinic three weeks later complaining he had been strip-searched twice in Manhattan subway stations."" -

Advances in Decentralized Peer Networks
PureFiction writes "Peer networks are gaining some attention these days given advances in much more decentralized search architectures and swarming distribution networks. Research has indicated that these decentralized networks are resistant to legal and technological attacks. The continued proliferation of broadband and wireless networking will ensure pervasive deployment of distributed peer networking infrastructure that will drive significant innovations in personal and community digital communications services." -
Mathematics Unravels Optimum Way To Lace Shoes
Seft writes "The knotty problem of choosing the optimum way of lacing up shoes has been solved by a new mathematical proof. There are many millions of different possibilities but, reassuringly, the proof shows that centuries of human trial and error has already selected out the strongest lacing patterns. However, the pattern using the least amount of lace possible, the decorative "bowtie" lacing, is usually only seen in shoe shop displays" -
Molecular Photography
med dev writes "An article at New Scientist discusses the latest in quantum computing - 1000 bits stored in the electron spins of a single polymer molecule. Add in a recent release of the how-to for the complete quantum computer, qubits that work, and it may not be much longer before Google is running on a server the size of a sugar cube." -

Hark! I Hear a Dropped Packet!
aarondsouza writes "The New Scientist has an article about Chris Chafe, a cellist and director of the Center for Computer Research in Music and Acoustics at Stanford University in California, who has the idea that one can use sound as an audible measure of the health of an internet connection. By sending a bunch of sound pulses across the line and measuring echo time, an average ping time of 10ms would be heard as a 100Hz tone. The idea is that the human ear is much more sensitive to variations in pitch, and thus "listening" to the connection would be a better indicator of its health. The article is short on technical specs but the project page (SoundWIRE) has more." -
Using Sound To Test Internet Connections
sifi writes "An article in the New Scientist claims that by converting the frequencies of a 'ping' to sound it is possible to hear the reliability and strength of an internet connection. They then go on to claim that all this is going to make telesurgery safe. I quite frankly think that this is a case of the media printing something becuase it sounds (pun intended) cool. I'm convinced that there's nothing here that couldn't be done with a suitably clever piece of software - unless I'm missing something." -

Interview with Brewster Kahle
Netmonger writes "A fascinating interview with the man behind The Wayback Machine. Some specs from the article: "It's 150-odd standard PC cases, with four drives in each.. 'Over 100 terabytes.. As plain text in book form, that'd be over 3000 miles of shelf space.." All I can say is.. Wow!" -
Backup Your Life on a DVD
matt20 writes "I've often wondered what it would take to condense the essence of my life and put it in a searchable format. Well, it looks like that may become a reality. Engineers are working on software to load every photo you take, every letter you write - in fact your every memory and experience - into a surrogate brain that never forgets anything. Here is the article found in New Scientist." -
Fast-Moving Black Hole
otisaardvark writes "New Scientist story about a very fast moving Black Hole in our very own Galaxy. Seems it was formed from a supernova explosion. I wish stars like this could have a more exciting name than GRO J1655-40 though. More at the BBC." -
Lightweight Radiation-proof Fabric?
kramer writes "New Scientist is reporting the creation of a lighweight radiation-proof fabric called Demron. Demron is being touted by its inventors as comparable to lead shielding at a fraction of the weight. Could be very useful for any future interplanetary space missions where the amount of radiation absorbed by the crew is a significant concern." -
Stanford Researchers Trying to Protect P2P Networks
dirvish writes "New Scientist has a story about efforts from researchers at Stanford to protect peer to peer networks from attacks that could be permitted by the proposed Berman Bill. Neil Daswani and Hector Garcia-Molina of the Database Research Department at Stanford University have mathematically modeled the Gnutella network to discriminate between nodes and supernodes. They then tested the nodes to find which rules could be applied to best avoid a malicious node on the network thus conserving bandwidth." -

Copy Protection On CDs Is 'Worthless'
zotler writes "NewScientist.com has an article about how copy protection on audio CDs is worthless. I thought this was funny since I just read this earlier Slashdot article 'BMG copy protecting all CDs'." The article also neatly sums up the technology behind current fair-use-inhibition stratagems. -

Proposed Next-Generation Space Station
WallytheWalrus writes "This NewScientist.com article discusses the proposed next generation of telescopes and space stations. The concept presented with little fanfare by the NASA Exploration Team (NEXT) consists of placing a space station about 5/6ths of the way to the moon at one of a handful of local Lagrangian Points. This station would act as a springboard for constructing new telescopic mirrors, maintaining the telescopes that use them, and as a haven for future manned exploration missions. If only NEXT's budget was more than $4 million a year...." -
Tweaked Genes Can Double Worm's Lifespan
jlechem writes ">New Scientist is reporting that U.S. scientists have doubled the life span of nematode worms with no apparent physiological side affects. Before scientists were able to double the worms lifespan but they were unable to reproduce. The breakthrough was achieved by turning certain genes on and off at certain times during the development cycle of the worms. While limited to worms right now, the researchers believe this could eventually lead to longer human lifespans. So what happens to those people who don't want to live forever?" -
