Submission + - Something in Deep Space Is Sending Signals to Earth in Steady 16-Day Cycles (vice.com)

schwit1 writes: A mysterious radio source located in a galaxy 500 million light years from Earth is pulsing on a 16-day cycle, like clockwork, according to a new study. This marks the first time that scientists have ever detected periodicity in these signals, which are known as fast radio bursts (FRBs), and is a major step toward unmasking their sources.

FRBs are one of the most tantalizing puzzles that the universe has thrown at scientists in recent years. First spotted in 2007, these powerful radio bursts are produced by energetic sources, though nobody is sure what those might be. FRBs are also mystifying because they can be either one-offs or “repeaters,” meaning some bursts appear only once in a certain part of the sky, while others emit multiple flashes to Earth.

Submission + - A Long-Lost Legendary Roman Fruit Tree Has Been Grown From 2,000-Year-Old Seeds (sciencealert.com)

schwit1 writes: Scientists have cultivated plants from date palm seeds that languished in ancient ruins and caves for 2,000 years.

This remarkable feat confirms the long-term viability of the kernels once ensconced in succulent Judean dates, a fruit cultivar lost for centuries. The results make it an excellent candidate for studying the longevity of plant seeds. ;

From those date palm saplings, the researchers have begun to unlock the secrets of the highly sophisticated cultivation practices that produced the dates praised by Herodotus, Galen, and Pliny the Elder.

"The current study sheds light on the origins of the Judean date palm, suggesting that its cultivation, benefiting from genetically distinct eastern and western populations, arose from local or introduced eastern varieties, which only later were crossed with western varieties," the researchers wrote in their paper.

Submission + - Internet Explorer antitrust case set to expire (networkworld.com) 1

jbrodkin writes: "The judgment in United States vs. Microsoft is on the verge of expiring nearly a decade after antitrust officials ruled Microsoft unfairly limited competition against its Internet Explorer browser. Microsoft has two more weeks to fulfill the final requirements in the antitrust case, which is scheduled to expire on May 12. Although Netscape ultimately didn't benefit, the settlement seems to have done its job. From a peak of 95% market share, by some estimates Internet Explorer now has less than half of the browser market. Microsoft, of course, filed its own antitrust action against Google this week, and even commented publicly on the irony of its doing so, noting that Microsoft has "spent more than a decade wearing the shoe on the other foot.""

Australian Stats Agency Goes Open Source 51

jimboh2k writes "The Australian Bureau of Statistics will use the 2011 Census of Population and Housing as a dry run for XML-based open source standards DDI and SDMX in a bid to make for easier machine-to-machine data, allowing users to better search for and access census datasets. The census will become the first time the open standards are used by an Australian Federal Government agency."

Lizard Previously Unknown To Science Found On Vietnam Menu 133

eldavojohn writes "A lizard long served on the menu in the Mekong Delta has recently caught the attention of scientists when it was noted that all animals in the species appeared identical as well as female. The species appears to be a hybrid of two other species (like a mule or liger). But the curious thing is that this hybrid isn't sterile — it reproduces asexually. The species, known for some time in Vietnam, has now officially been named Leiolepis ngovantrii."

Building a Telegraph Using Only Stone Age Materials 238

MMBK writes "It's the ultimate salvagepunk experiment, building a telegraph out of things found in the woods. From the article: 'During the summer of 2009, artist Jamie O’Shea of the organization Substitute Materials set out to test whether or not electronic communication could have been built at any time in history with the proper knowledge, and with only tools and materials found in the wilderness of New Jersey.'"

Submission + - Microsoft looks to courts for botnet takedowns (idg.com.au)

angry tapir writes: "Microsoft has seen a dramatic drop in the number of computers infected with Waledac, a piece of malicious software affiliated with a botnet that was once responsible for a massive amount of spam. In the second quarter of this year, the company cleaned only 29,816 computers infected with Waledac, down from 83,580 computers in the first quarter of the year. The drop in the number of infected machines shows the success of the legal action Microsoft took earlier in the year, according to the company."

The Perfect Way To Slice a Pizza 282

iamapizza writes "New Scientist reports on the quest of two math boffins for the perfect way to slice a pizza. It's an interesting and in-depth article; 'The problem that bothered them was this. Suppose the harried waiter cuts the pizza off-center, but with all the edge-to-edge cuts crossing at a single point, and with the same angle between adjacent cuts. The off-center cuts mean the slices will not all be the same size, so if two people take turns to take neighboring slices, will they get equal shares by the time they have gone right round the pizza — and if not, who will get more?' This is useful, of course, if you're familiar with the concept of 'sharing' a pizza."

The Psychology of Achievement In Playing Games 80

A post on Pixel Poppers looks at the psychological underpinnings of the types of challenges offered by different game genres, and the effect those challenges have on determining which players find the games entertaining. Quoting: "To progress in an action game, the player has to improve, which is by no means guaranteed — but to progress in an RPG, the characters have to improve, which is inevitable. ... It turns out there are two different ways people respond to challenges. Some people see them as opportunities to perform — to demonstrate their talent or intellect. Others see them as opportunities to master — to improve their skill or knowledge. Say you take a person with a performance orientation ('Paul') and a person with a mastery orientation ('Matt'). Give them each an easy puzzle, and they will both do well. Paul will complete it quickly and smile proudly at how well he performed. Matt will complete it quickly and be satisfied that he has mastered the skill involved. Now give them each a difficult puzzle. Paul will jump in gamely, but it will soon become clear he cannot overcome it as impressively as he did the last one. The opportunity to show off has disappeared, and Paul will lose interest and give up. Matt, on the other hand, when stymied, will push harder. His early failure means there's still something to be learned here, and he will persevere until he does so and solves the puzzle."

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."
