Bismillah writes: China Telecom is up to no good with Border Gateway Protocol (BGP) shenanigans researchers have discovered. The state-owned telco is hijacking and rerouting internet traffic to China via it's U.S. and Canadian points of presence (PoPs). As for how the researchers came to their conclusion, they reportedly "built a route tracing system that monitors BGP announcements and which picks up on patterns suggesting accidental or deliberate hijacks and discovered multiple attacks by China Telecom over the past few years," reports iTNews.

In one example occurring in 2016, "China Telecom diverted traffic between Canada and Korean government networks to its PoP in Toronto," the report says. "From there, traffic was forwarded to the China Telecom PoP on the U.S. West Coast and sent to China, and finally delivered to Korea. Normally, the traffic would take a shorter route, going between Canada, the U.S. and directly to Korea." The telecommunications company is able to reroute the traffic by announcing fake routes via the BGP, which "governs data flow between Autonomous Systems, the large networks operated by telcos, internet providers and corporations."

An anonymous reader writes "For reasons that scientists have not conclusively determined, women are happier than men. And now, researchers think that they may have pinpointed one of the reasons for that. They have found a gene in women that predicts the level of happiness in women. 'After controlling for various factors, ranging from age and education to income, the researchers found that women with the low-expression type of MAOA were significantly happier than others. Compared to women with no copies of the low-expression version of the MAOA gene, women with one copy scored higher on the happiness scale and those with two copies increased their score even more. While a substantial number of men carried a copy of the "happy" version of the MAOA gene, they reported no more happiness than those without it.'"

New submitter sjdupont writes "A trio of University of South Florida (USF) engineering graduate students have decided to make a change in science, technology, engineering, and mathematics (STEM) education in an unusual and exciting way: by creating their own superhero personas and dressing in costumes as members of the Scientific League of Superheroes. Focused on elementary education, they have created a unique education program called the Superhero Training Network, a curriculum-based video series designed for the classroom which focuses on teaching STEM topics while engaging students in a fun way. Fifth grade classrooms in Hillsborough County (Florida) pilot tested the series during the 2011-2012 school year and enjoyed visits from the scientific superheroes to experience scientific demonstrations and participate in hands-on activities."

Richard Pritches writes in to let us know that MIT errata expert Evangelos Georgiadis has disproved 44 conjectures set by Dr. Stephen Wolfram (founder of Mathematica) in A New Kind of Science. The paper was published in the latest issue of the Journal of Cellular Automata and can be read in PDF form at Prof Edwin Clark's collection of reviews of Wolfram's ANKS. "The formulas provided by Wolfram for these [44] rules are not minimal. Moreover for 8 of these cannot be minimal even by simple inspection since minimal formula sizes for 3-input Boolean functions over this basis never exceeds 5."

ChamaraG asks: "Do you enable power management in your desktop PCs, and have you had any problems with networking after enabling power management (problems like losing open network connections, network using applications hanging after resuming from low power states, etc)? To clarify, by desktop PCs I mean PCs compliant with ACPI and Wake-On-LAN and capable of resuming from low power states in a few seconds, so that waking up time is not an issue. I am interested in the energy efficiency of networks and networked devices and I would like hear of problems that you might have had. Some applications I have tested will disable power management settings, presumably in order to maintain network connectivity. Surveys by the Lawrence Berkeley National Laboratory show that less than 5% of desktop PCs in offices are in low power states at night (36% - off, 60% - on). So, do you enable or disable power management in your PCs? If power management is disabled, what prompted you to do so and what would make you enable power management? What connectivity related problems did you encounter after enabling power management?"

Dr. Robin Murphy writes "An editorial comparing the proposed roborats with the rescue robots actually used at the WTC response by the Center for Robot-Assisted Search and Rescue appeared last month in IEEE Intelligent Systems Magazine. A slightly longer version is at Crasar.org. Note that the rescue robots was in Discover Magazine's Top 100 stories of 2002."

Jon Bardin asks: "I am currently living in a dorm at the University of South Florida. The dorms come wired straight to the Internet and my connection is pretty zippy, because I have seen 2 megabytes per second download speed. I was wondering if there was a way, with the new fancy 2.4 Linux kernel, that I could shotgun at least two of the eight ethernet ports in my suite together, as to effectively double or quadruple my download speed. It doesnt have to be a Linux solution either its just all this talk about the fancy TCP/IP stack and firewalling has me thinking about things. The ethernet ports are configured by DHCP and are reasonably static... I got a new IP when I got back from winter break. so any help would be greatly appreciated." This question gets asked a lot. I wasn't quite sure if this was possible for the 2.2.x kernels, but I figure it might be time to ask this now that 2.4 has been released.
