Skulls of the Shogun offers game syncing across Windows, Windows Phone and Xbox (video)

Skulls of the Shogun brings true game sync across Windows, Windows Phone and Xbox video

Cross-platform game compatibility and syncing aren't anything new, but there have been few if any games that truly make us feel at home when we switch devices. Developer 17-Bit's just-launched Skulls of the Shogun bucks that trend in style as the first game with a unified experience across every one of Microsoft's platforms. Start a game on a Windows 8 or RT PC, Windows Phone or Xbox 360, and cloud saves will carry over with nary a hitch in sight. Turn-based multiplayer works the same way: anyone involved in a match can play from whichever device is convenient, rather than give up a big screen or mobility. We just wish the undead strategy game's prices enjoyed the same level of consistency -- Skulls costs $5 on Windows Phone, $10 on Windows PCs and 1,200 points on the Xbox. Still, we'll bite if it means squeezing in one more round on our Surface.

Giant Carbon Molecules for Sustainable Technologies

Jan. 31, 2013 ? Scientists in the joint research project "FUNgraphen" are pinning their hopes for new technologies on a particular form of carbon: They have developed new carbon macromolecules and molecular carbon composite materials with special properties. The molecules are derived from graphene, a substance that consists of individual layers of carbon atoms arranged in a honeycomb-like pattern. The process previously necessary to make use of this substance was complex and expensive and thus of little value for most plastics applications.

A research group at the Freiburg Materials Research Center (FMF) of the University of Freiburg led by the chemist Prof. Dr. Rolf M?lhaupt, managing director of the FMF, has now succeeded in combining graphene with polymers, making them fit for plastics applications, and preparing them for material optimization on a kilogram scale. The project "FUNgraphen," funded by the Federal Ministry of Education and Research, is being coordinated at the FMF with support from an industrial advisory board. The other project partners besides the FMF are the University of Bayreuth, the Federal Institute for Materials Research and Testing (BAM) in Berlin, and the Fraunhofer Institute for Mechanics of Materials in Freiburg.

In the FMF processes individual layers of carbon atoms, derived from natural graphite and also renewable carbon sources, are physically and chemically attached to polymers. The result is giant molecules of carbon, so-called macromolecules, which are less than a millionth of a millimeter thick but can achieve widths of more than a hundredth of a millimeter. The resulting carbon macromolecules and carbon polymer hybrid materials are light, durable, environmentally friendly, and electrically conductive. Moreover, they are resistant to heat, chemicals, and radiation and are impermeable to gas and liquids. "They have the potential to vastly improve resource and energy efficiency of plastics," says M?lhaupt.

In addition, the researchers dispersed several of these large carbon molecules in water, nontoxic solutions, and plastics to produce concentrated stable dispersions without requiring either binders or dispersing aids. These mixtures can be used to coat surfaces and print conductive carbon films as well as electrically conducting micro patterns. In this way, carbon can replace expensive transition metals like palladium or indium. "The applications range from printed electronics to printed catalysts with a pore design for the production of fine chemicals with simple catalyst recovery," says M?lhaupt. The printed conductive carbon layers are much more mechanically robust than printed indium tin oxide layers. The scientists at the FMF also succeeded in mechanically reinforcing plastics and rubber with carbon macromolecules and simultaneously making them electrically conductive, resistant to radiation, and more gas-tight. These substances are interesting candidates for application in antistatic and impermeable fuel tanks and fuel lines, casings that are shielded against electromagnetic interferences, and gas-tight automobile tires for reducing fuel consumption in transportation.

Examples from the project partners' research also show that carbon macromolecules are far more versatile than the carbon nanoparticles typically used today, thus opening up new potential for the development of sustainable materials and technologies. Prof. Dr. Volker Altst?dt from the "FUNgraphen" team at the University of Bayreuth was able to substantially reduce the cell sizes in foams by adding carbon macromolecules. This will allow the researchers to improve the thermal insulation properties of foams and develop new, highly efficient insulating material. The "FUNgraphen" group led by Dr. Bernhard Schartel at the BAM has succeeded in increasing the fire protection effect of halogen-free flame retardants by adding tiny admixtures of the new carbon macromolecules. A plastic equipped with this new material does not catch fire even after a flame has been applied to it several times -- unlike unprotected plastics, which become deformed at high temperatures and start to burn immediately when they come into contact with fire.

STI Rate Higher Among Military Women Than Civilian Women ...

The rate of STIs among military women is higher than that in civilian women, according to a recent study in the Journal of Women's Health.

The study, conducted by researchers at Women & Infants Hospital of Rhode Island, shows that the STI rate is seven times higher among military women than civilian women.

The researchers also found that only about one in three unmarried military women who are sexually active used a condom during the last time they had sexual intercourse, and that nearly two in three of them had more than one sexual partner over the last year.

The findings are based on reviewing past research on STI rates among military members.

"These high-risk sexual practices likely contribute to chlamydia infection rates that are higher than the rates in the U.S. general population," the researchers wrote in the study.

"To address the reproductive health needs of military women, investigations into the prevalence of unsafe sexual behaviors and consequent infection among older servicewomen and women veterans are needed," they wrote. "Direct comparison of military and civilian women is needed to determine if servicewomen are a truly high-risk group."

According to the latest data on STIs in the United States, there were about 1.4 million cases of chlamydia, nearly 322,000 casse of gonorrhea, and 13,970 non-congenital cases of syphilis reported in the U.S. in 2011. Young people and gay and bisexual men are at the highest risk for STIs, according to the Centers for Disease Control and Prevention.

(AP) ? Flammable and toxic foam soundproofing on the ceiling. Just one exit for a large club that could hold hundreds of people. Not a ceiling water sprinkler system in sight.

These are some of the main causes of the massive death toll in a nightclub fire in Brazil ? and none broke any law, raising questions about safety regulations in a nation set to host the World Cup and Olympic Games.

Documents obtained by The Associated Press, including past building and fire safety plan permits issued to the Kiss club, where 234 people died within minutes in a fire early Sunday, showed that such deadly choices were within regulations.

"Do I agree with the fact that there was only one exit? No. Do I agree that the roof was covered with flammable material? No, I don't," said Maj. Gerson Pereira, an inspector with the local fire department. "I would have liked to shut down this place, but then the firefighters could be sued" because no law had been broken.

But the same documents also illustrate that other regulations were broken, including irregularities in the fire safety inspection of the club, as well as violations by the band the club hired whose pyrotechnics are blamed for causing the blaze. Police inspectors say any of these violations were reason enough to shut the club down.

One document shows that the club had already been labeled by fire officials as being at "medium" risk for having a fire. By state law, that designation requires that the club undergo annual inspections. But records show that the last inspection took place in August 2011.

Survivors of the fire have said that the club's fire extinguishers failed to work in early attempts to battle the blaze. Under state law, an extinguisher must have a receipt showing that it had been independently inspected within a year in order for it to be acceptable.

Marcelo Arigony, the lead police investigator in the case, said in a Tuesday press conference that it was clear the fire extinguishers had not been inspected and that they were clearly cheap models that should not be used anywhere.

Perhaps most egregious was what authorities point to as the cause of the fire.

The blaze began at around 2:30 a.m. local time during a performance by Gurizada Fandangueira, a country music band that had made the use of pyrotechnics a trademark of their shows. The band's guitarist told media that the 615-square-meter (6,650-square-foot) club was packed with an estimated 1,200 to 1,300 people, the same estimate police have given. Capacity for the club, however, is under 700.

Police said that members of the band knowingly bought flares meant for outdoor use because they cost a mere $1.25 a piece, compared with the $35 price tag for an indoor flare.

"It's not that this club was working to come within this or that law ? the place should have never been open in the first place," Arigony said. "This is a problem that is seen across Brazil, these laws. I can only hope this tragedy brings about change."

Jaime Moncada, a U.S.-based fire-safety consultant with nearly three decades experience in Latin America including large projects in Brazil, said he was not surprised that one exit was permissible under local law.

Shown a blueprint of the club obtained by the AP, he calculated that the farthest point from the front door was 105 feet (32 meters), and regulations in most Brazilian states dictate that a second exit is required only if the distance is 131 feet (40 meters) or more.

For the same reason of distance, Moncada said sprinklers and alarms would not be required.

"For an American audience, it is crazy to think that a place would have only one exit," he said.

In Brazil, he added, that would be the norm.

In the United States, the club would have failed an inspection in at least three ways, according to Moncada: Three separate exits would have been required; the foam would need to be treated with a fire retardant; and it would need sprinklers.

Amid the shock of what was the world's deadliest nightclub fire in a decade, changes in Brazil seemed on the horizon.

In Brasilia, the nation's capital, lawmakers in the lower house worked on a proposal that would require federal safety minimum standards across Brazil. Now states individually create such laws. The O Globo newspaper reported on its website that the mayor's office in Santa Maria ordered all nightclubs closed for 30 days while inspections are carried out.

Elsewhere, the government of the country's biggest city, Sao Paulo, set to host the opening match of the 2014 World Cup, promised tougher security regulations for nightclubs.

The Folha de S. Paulo newspaper reported that in Manaus, which will also host World Cup matches, nightclubs with empty fire extinguishers and unmarked emergency exits have been shut down and fined. And in Olympic host city, Rio de Janeiro, a consumer complaint hotline has received more than 60 calls since Sunday's tragedy denouncing hazardous conditions at night spots, theaters, supermarkets, schools, hospitals and shopping malls.

Outraged citizens in Santa Maria are demanding change.

Elise Parode, an 18-year-old student taking part in a protest before City Hall, chanted with all her might along with about 500 others, pushing up against the door of the building as municipal guards kept them from entering.

"We want justice! We want the government held accountable, just like the owners of the bar!" she yelled as the crowd around held aloft poster-size photos of the fire's victims. "Our own government doesn't know the laws ? we're not safe until they do."

Green Tea and Viagra: A Recipe for Fighting Cancer?

Discovered: Erectile dysfunction meds and green tea team up to fight cancer; cell phone towers are responsible for many bird deaths; look at this tractor beam in action; shooting your belly full of botox won't make you skinny.

The cancer-fighting properties of green tea and erectile dysfunction meds. Ever wonder why men who drink green tea and have Viagra prescriptions live so long? Of course you didn't, nobody wonders that. But according to a new study led by Kyushu University's Hirofumi Tachibana, it could be true! He gave mice suffering from cancer a cocktail of green tea and PDE5 inhibitors (the kind of drug in Viagra, Cialis, Levitra, and other brands of erectile dysfunction medication), finding that malignant cells stopped growing when subjects took the healthy/arousing mixture. The EGCG catechin found in green tea has long been thought to have cancer fighting properties, but Tachibana's work shows that the PDE5 enzyme could be stifling it. Luckily, we already have a drug that suppresses PDE5, and it just happens to be used for erectile dysfunction. Tachibana warns the public from trying this remedy at home right now, and in the meantime researchers in the U.S. plan to set up human trials this year.?[The Japan Times]

Cell phone towers are killing many birds. The verdict's out on cell phones' link with brain cancer, but it's very clear cell phones are having a negative effect on bird populations. Around 7 million birds have been killed each year by flying into cell towers, according to a new paper in Biological Conservation. And many of them are rare species, such as the yellow rail (2,000 die from cell phone tower collisions each year, and there are only about 20,000 total). Researchers suggest that affixing blinking red lights to the towers could lower deaths by 70 percent. [Scientific American]

No, injecting botox into your belly won't make you skinny. It might iron out the wrinkles in your stomach skin, but injecting Botox into your belly won't slim you down according to a new study from the Mayo Clinic. Data on this was split previously, with some researchers saying that botulinum toxin A injections could reduce waistline fat by delaying emptying of the stomach. This would induce a great feeling of fullness and discourage?overeating, the thought went. But the Mayo Clinic's Mark Topazian and his colleagues found no evidence that the injections corresponded with weight loss. ""On the basis of our findings, I would not recommend gastric Botox injections to people who want to lose weight. There are some risks with this treatment and we found that there was no benefit in terms of body weight loss," Topazian says. "Unless future studies show different results I'd advise patients to seek other means of achieving weight loss."?[American Gastroenterological?Association]
