Comments: 6 +-   Algae Could Be the Key To Ultra-Thin Batteries on Friday November 27, @10:10PM

MikeChino writes "Algae is often touted as the next big thing in biofuels, but the slimy stuff could also be the key to paper-thin biodegradable batteries, according to researchers at Uppsala University in Sweden. Uppsala researcher Maria Stromme and her team has found that the smelly algae species that clumps on beaches, known as cladophora, can also be used to make a type of cellulose that has 100 times the surface area of cellulose found in paper. That means it can hold enough conducting polymers to effectively recharge and hold electricity for long amounts of time. Eventually, the bio batteries could compete with commercial lithium-ion batteries."

Comments: 18 +-   3D Video Game Collaboration Used To Solve Crimes on Friday November 27, @08:14PM

eldavojohn writes "Reuters explains how the National Science Foundation's Cyber-Enabled Discovery and Innovation (CDI) program is funding research used to implement real life crimes in a CSI-like game. They will use IC-CRIME's laser scanner technology and the Unity platform (which recently enjoyed the release of a freeware version) to recreate the crime scene as closely as possible. The crime scene will then be hosted for multiple remote crime scene investigators to explore concurrently while discussing what they see, sharing their data and experience as well as learning and asking questions."

space
al0ha writes "In the first video showing the auroras above the northern latitudes of Saturn, Cassini has spotted the tallest known 'northern lights' in the solar system, flickering in shape and brightness high above the ringed planet. The new video reveals changes in Saturn's aurora every few minutes, in high resolution, with three dimensions. The images show a previously unseen vertical profile to the auroras, which ripple in the video like tall curtains. These curtains reach more than 1,200 kilometers (750 miles) above the edge of the planet's northern hemisphere."

Comments: 130 +-   Google Attack On the Mobile Market Rumored on Friday November 27, @06:35PM

google
xchg writes in with a somewhat speculative, though plausible, piece from WiseAndroid claiming that Google is gearing up for an all-out assault on the mobile-phone market that will include a new, Google-branded handset and the first comprehensive Google phone service with unlimited free calls. "The real breakthrough, however, will come with the marriage of the Googlephone to Google Voice, the Californian company’s high-tech phone service. Google Voice gives US users a free phone number and allows unlimited free calls to any phone in the country — landline or mobile. International calls start from... just over a penny a minute. Google Voice also uses sophisticated voice recognition to turn voicemails into emails, can block telemarketing calls automatically and offers free text messaging. Google sounded its intentions two weeks ago when it purchased a small company called Gizmo5... [E]xperts are predicting that the Googlephone will be launched in the US early next year."

siddesu writes in with "compelling" new data that chemical and fossil evidence of ancient microbial life on Mars was carried to Earth in a Martian meteorite. The finding is being highlighted by the same NASA team who made the initial discovery 13 years ago. Spaceflight Now has more details of the analysis.

court
bennyboy64 writes "The Australian court case between the film industry and ISP iiNet drew to a close yesterday after the film studios issued an ultimatum: Take copyright responsibilities seriously or leave the industry. 'Businesses such as ISPs want to enjoy the benefit of being able to make money out of the provision of Internet service facilities and they enjoy that benefit. But it carries with it a responsibility,' said Tony Bannon SC, the film industry's lawyer. 'They provide a facility that is able to be used for copyright infringement purposes. If they don't like having to deal with copyright notices then they should get out of the business.' iTnews has done a short one minute interview with iiNet's CEO Michael Malone as he left the court on the final day. Also on the final day, the judge dismissed the Internet Industry Association's involvement in the case."

medicine
SubComdTaco writes "Harvard has announced their approach towards an implantable cancer vaccine (press release here). To anyone familiar with how the immune system works, this appears to be a synthetic lymph node, an intriguing bit of biomimicry. From the Science Daily article: 'A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals, scientists recently reported in the journal Science Translational Medicine. The new approach, pioneered by bioengineers and immunologists at Harvard University, uses plastic disks impregnated with tumor-specific antigens and implanted under the skin to reprogram the mammalian immune system to attack tumors. The new paper describes the use of such implants to eradicate melanoma tumors in mice. ... The slender implants... are 8.5 millimeters in diameter and made of an FDA-approved biodegradable polymer. Ninety percent air, the disks are highly permeable to immune cells and release cytokines, powerful recruiters of immune-system messengers called dendritic cells. These cells enter an implant's pores, where they are exposed to antigens specific to the type of tumor being targeted. The dendritic cells then report to nearby lymph nodes, where they direct the immune system's T cells to hunt down and kill tumor cells.'"

networking
soulprivate writes "My cable company has recently begun to offer Internet access plans with speeds over 30 Mbps (60, 80 and 100 Mbps). However my D-link router is unable to go beyond 30 Mbps if I use NAT; it reaches 60-70 Mbps only if NAT is disabled. Is there any recommendation for a brand/model of residential router that is able to get more than 70 Mbps with NAT enabled? I have been looking for benchmarks or comparisons, to no avail. Does anyone know one? What are your experiences at home?"

Comments: 554 +-   Engaging With Climate Skeptics on Friday November 27, @03:02PM

earth
In the wake of the CRU "climategate" leak, reader Geoffrey.landis sends along a New York Times blog profile of Judith Curry, a climate scientist at Georgia Tech. "Curry — unlike many climate scientists — does not simply dismiss the arguments of 'climate skeptics,' but attempts to engage them in dialogue. She can, as well, be rather pointed in criticizing her colleagues, as in a post on the skeptic site climateaudit where she argues for greater transparency for climate data and calculations (mirrored here). In this post she makes a point that tribalism in science is the main culprit here —- that when scientists 'circle the wagons' to defend against what they perceive to be unfair (and unscientific) attacks, the result can be damaging to the actual science being defended. Is it still possible to conduct a dialogue, or is there no possible common ground?"

blee37 writes "Here is an excellent video demonstration of a new program developed by Qi Pan, a graduate student, and other researchers at the University of Cambridge. The 'ProFORMA' software constructs a 3D model of an object in real time from (commodity) webcam video. The user can watch the program deduce more pieces of the 3D model as the object is moved and rotated. The resulting graphics are of high quality."
