4dp. Dark matter, WIMPS, and NASA's Alpha Magnetic Spectrometer data. Recently the media has been saturated with overly-hyped reports that NASA's Alpha Magnetic Spectrometer (AMS) may have detected dark matter. These claims may have some justification if the word "may" is shouted, but they rest on a number of really major assumptions and guesses, some of which are on weak and shifting soil. So just what was seen in the experiment, and what are the possible explanations? Antimatter – setting the stage Cars, trucks, planets, and other materials which we encounter in everyday life are composed of subatomic particles such as electrons, proton, and neutrons. However, another kind of matter known as antimatter was first predicted by Paul Dirac in 1931, followed quickly by Carl Anderson's discovery in 1932 of the antielectron, or positron, in cosmic rays.
Each of the subatomic particles we know has an antiparticle, which have the same mass as their corresponding subatomic particles, but with the opposite charge. How is antimatter detected?

Four generations of the Higgs Boson More than 400 people, including 100 secondary school students, packed the JH1 auditorium at NUI Maynooth on Friday May 3rd to hear Professor Peter Higgs and his colleagues talk about the Higgs Boson and its discovery. Peter Higgs, of Edinburgh University, predicted the existence of this particle in 1964, and its discovery at CERN last year provided the final piece of experimental confirmation for our theory of the fundamental constituents of matter, known as the "Standard Model".
The hunt for the Higgs particle has long been one of the top priorities for particle physics. The Higgs is associated with a mechanism proposed in the mid-1960s to explain why one of nature's fundamental forces has a very short range while a similar force has infinite range. The electromagnetic force is carried by particles called photons, which have no mass, whereas the weak force is carried by particles called W and Z that do have mass. Prof. Ends. Software News - Software Development News, Internet, World Wide Web. International Space Station making laptop migration from Windows XP to Debian 6. (Phys.org) —The International Space Station has decided to switch dozens of laptops running Windows XP over to Debian. What Linux fans have been saying for years—that Linux delivers greater stability and reliability for public and private computing environments—resonated with Keith Chuvala, the United Space Alliance contractor manager involved in the switch.
The change at the International Space Station is all about the replacement of dozens of laptops with XP being switched over to Debian 6. Chuvala said, "We needed an operating system that was stable and reliable – one that would give us in-house control. So if we needed to patch, adjust or adapt, we could. " Although Linux machines, like Windows, are not malware-proof, the fact that Linux is an open source operating system means that a community overseeing a Linux distribution can issue quick notices and quick patches. Chuvala and NASA selected Debian, a system that uses Linux or the FreeBSD kernel. The ISS adopted Debian 6. Hints of lightweight dark matter get even stronger - space - 10 May 2013. A strange light is shining near the centre of the Milky Way, and evidence is mounting that it is the spark of lightweight dark matter meeting a violent end.
At the same time, a suite of sensitive detectors deep underground is seeing hints of similar particles. Dark matter is thought to make up roughly 80 per cent of the matter in the universe. But aside from its gravitational tug on regular matter, the substance has proven tough to detect, and many of its fundamental properties remain unknown. The leading theoretical candidates for dark matter are weakly interacting massive particles (WIMPs). Last year scientists ruled out a possible Fermi signal at 130 gigaelectronvolts (GeV) as dark matter's smoking gun. Unusual suspects That signal has been controversial, in part because it had only been seen very close to the centre of the Milky Way, in a violent region filled with hot gas, newborn stars, supernovae and a supermassive black hole – any of which could be throwing off spare gamma rays.
One-Fourth of DNA Born by 2.8 Billion Years Ago | Wired Science. Using the genetic equivalent of the Hubble telescope, researchers have peered into the distant past and witnessed an explosion of new genes that happened more than 3 billion years ago. About 27 percent of all gene families that exist today were born between 3.3 billion and 2.8 billion years ago, two researchers from MIT reported online Dec. 19 in Nature.
The surge of gene births — which the scientists have dubbed the Archean expansion — predate some important changes in Earth’s early chemistry, including the appearance of large amounts of oxygen in the atmosphere, say evolutionary biologists Eric Alm and Lawrence David. The study may show how early organisms responded to and helped alter the planet’s chemistry. Daniel Segrè, a computational biologist at Boston University, says that the work provides “insight into really ancient metabolic events.” Fossils of organisms billions of years old are difficult to find.
Image: Flickr/A Hermida See Also: The “urban advantage” in education. By Marilyn AchironEditor, Directorate for Education and Skills On average across OECD countries, students who attend schools in cities of more than 100 000 people perform better in PISA than students who attend schools in villages, rural areas, or towns with up to 100 000 inhabitants. This difference in performance translates to about 20 PISA score points – the equivalent of half-a-year of schooling.
In many countries and economies, the performance difference between the two groups of students reflects families’ decisions about housing and employment, which, in turn, influence how students’ socio-economic status is distributed geographically. In all countries and economies except for Austria, Belgium, Germany, Israel, Korea, the Netherlands, the United Kingdom and the United States, students who attend schools in urban settings come from more advantaged socio-economic backgrounds. What this tells us is that some of the conventional wisdom about big city schools may be a little off. Home.

ELSA - Particle Accelerators Around the World. Voices in Europe Claim: “Europe for the People, Not the Markets”
From March 11 to 17 European citizens organized a week of protests against the austerity measures imposed on the countries of the European Union as a strategy for ending the economic crisis. Known as the European Counter Summit [es], it is the response to the European Summit in which European leaders gathered [es], and an occasion to make the voices heard of those citizens who defend a “Europe for the people and not for the markets“.
They also reject the negative effects of the policies of cuts and they demand a series of changes in the European Union. People from different countries have protested in the streets and commented on the events through Twitter under the tag #EuropeanSpring. Press conference in front of the office of the EU in Madrid.

The Truth behind the "'Biggest Cyber Attack in History" Is it "the biggest cyberattack in history"? Or just routine flak that network-security providers face all the time?
News websites across the Western world proclaimed Internet Armageddon today (March 27), largely due to a New York Times story detailing a "squabble" between the spam-fighting vigilantes at Spamhaus and the dodgy Dutch Web-hosting company Cyberbunker. "Fight Jams Internet," the Times headline said. "Global Internet slows," the BBC proclaimed in the wake of the Times' story.
Both websites alleged that Netflix streaming was slowing down as a result. The reality is less exciting, though still serious. But, if anything, the incident may prompt a fix for a basic security flaw in the Domain Name System that serves as one of the underpinnings of the Internet. Boston-based Akamai Networks told the Times, and Spamhaus told the BBC, that the last round of attacks peaked at 300 gigabits per second, possibly the largest amount of bandwidth ever recorded during a DDoS attack. The Importance of Studying the Obvious - Duncan Watts.
By Duncan Watts | 12:25 PM June 25, 2012 When Congressman Jeff Flake recently proposed eliminating NSF funding for political science research, it marked the third time in the past 6 years that a member of Congress had introduced legislation to cut federal support for some or all of social science. To make his case, Congressman Flake picked out some examples of political science research that had been funded by the NSF and argued that the research in question— $600,000, in one case, to figure out if policymakers actually do what citizens want them to; $200,000 in another to understand why politicians make vague statements — was of little value to society, and therefore not worth the expense to taxpayers. At first glance, the cost of these projects does seem hard to justify. I have no doubt that these are worthy projects, having passed a rigorous and highly competitive process of expert review. I’m not prepared to second-guess this process, and neither presumably is Congressman Flake.
