Goldbach Conjecture: Closer To Solved? 170

mikejuk writes "The Goldbach conjecture is not the sort of thing that relates to practical applications, but they used to say the same thing about electricity. The Goldbach conjecture is reasonably well known: every integer can be expressed as the sum of two primes. Very easy to state, but it seems very difficult to prove. Terence Tao, a Fields medalist, has published a paper that proves that every odd number greater than 1 is the sum of at most five primes. This may not sound like much of an advance, but notice that there is no stipulation for the integer to be greater than some bound. This is a complete proof of a slightly lesser conjecture, and might point the way to getting the number of primes needed down from at most five to at most 2. Notice that no computers were involved in the proof — this is classical mathematical proof involving logical deductions rather than exhaustive search."

Apple Developing Tool To Remove Flashback 212

Trailrunner7 writes, quoting Threatpost: "Apple is planning to release a software fix that will find and remove the Flashback malware that has been haunting Mac users for several months now. ... Apple said on Tuesday that it was in the process of developing a tool that would detect and remove Flashback, but the company did not specify when the fix would be available. Security researchers and customers have been questioning why Apple hasn't yet provided a fix for the malware even though Flashback has been around in one form or another for more than six months now."

Scientists Work Towards Naturally Caffeine-Free Coffee 312

First time accepted submitter eternaldoctorwho writes "Research has been underway to produce a coffee bean plant that naturally has no or little caffeine content. Now, it looks like that might become a reality in the near future: Paulo Mazzafera of the University of Campinas in Brazil has come closer than ever with a strain containing 'only 2% of normal caffeine levels.' Coffee, anyone?"

Majorana Fermion May Have Been Spotted At TU Delft 73

vikingpower writes "A research group at Technical University Delft around prof. Kouwenhoven has probably not only spotted pairs of so-called Majorana Fermions for the first time (these had been predicted to exist by the Italian physicist Ettore Majorana), but also demonstrated that, by generating them at the end of an Indium-Arsenide microwire, quantum computing with them may have come one more step closer to reality. The excitement around Prof. Kouwenhoven at the American Physical Society annual congress in Boston, after he completed his presentation, was considerable.A nice illustration is provided by this newspaper article (in Dutch)."

One Million Web Pages Attacked By Lilupophilupop 120

hankwang writes "The Internet Storm Center reported that one million web pages have been attacked by the Lilupophilupop SQL injection and contain a malicious Javascript link. Affected sites can be found using a Google search query. See also the technical details of the SQL injection. The attack is directed to sites running ASP or ColdFusion with an MSSQL backend. The payload of the Javascript leads, via redirects and obfuscated Javascript, to a fake download page for Adobe Flash and antivirus software."

Scientists Plan "Artificial Volcano" Climate Experiment 292

First time accepted submitter tonyt3 writes "Scientists plan on conducting an unusual climate experiment at a Norfolk airfield next month. They plan to spray water into the air about 20 km high to mimic volcanic particles, hoping that their findings could lead to a solution to global warming. From the article: 'Pouring 10 million tonnes of material into the stratosphere each using 10 to 20 giant balloons could achieve a 2C global drop in temperature, the scientists believe. Sulphate emissions from the Mount Pinatubo eruption in the Philippines in June 1991 reduced world temperature by 0.5C for two years.'"

US Navy Breaks Laser Record 294

ectotherm writes "The US Navy has broken the existing record for the power of a laser. Their new free-electron laser can burn through 20 feet of steel per second. 'Next up for the tech: additional weaponization. The Navy just awarded Boeing a contract worth up to $163 million to take that technology and package it as a 100 kW weapons system, one that the Navy hopes to use not only to destroy things but for on-ship communications, tracking and detection, too — using a fraction of the energy such applications use now, plus with more accuracy.' Now all we need to do is upgrade the sharks..."

UK Minister Backs 'Two-Speed' Internet 226

Darkon writes "UK Culture minister Ed Vaizey has backed a 'two-speed internet', letting service providers charge content makers and customers for 'fast lane' access. It paves the way for an end to 'net neutrality' — with heavy bandwidth users like Google and the BBC likely to face a bill for the pipes they use."

Bredolab Botnet Taken Down 187

Leon Buijs writes "Monday a 27-year-old Armenian was arrested at request of the Dutch authorities. The Dutch police think he is the brain behind the infamous, 30 million infected computers large Bredolab network, that was taken down by their Team (in Dutch) High Crime. Bredolab was used to spread virii and spam via the Netherlands. While taking the botnet down at a Dutch ISP, the suspect did several attempts to regain control. When this didn't work out, he did a DDoS attack on the ISP's servers using a 220,000 computers botnet. However, this was also broken off by taking 3 servers offline that the Armanian used for this, in Paris."
