and when you experience heatwaves that can give you sunburn even with 30+ lotion on

Temperature has no impact on rate of sunburn, angle of the sun does. You are more likely to burn during a heat wave because of the angle, but you can still get a bad sunburn during the winter because of the reflected light from the snow. A heat wave will however bring on increased rates of heat related illness, but sunscreen will not have any impact on the severity of the illness.

Comment Re:10% Ethanol (Score 1) 556

Octane is an added to prevent detonation. Higher compression engines require higher octane ratings to prevent said detonation. They claim you get the most out of E85 when it is burned at a much higher compression ration that E10, which is why it is sold with 105 octane. However all cars are "Flex Fuel" which means they have the lower compression ratio to allow for the use of E10, which makes the 105 octane rating pointless, unless you blend. - IE 33% E85 105 octane and 67% E10 87 octane for a net of E35 with 93 octane if you run with performance mods that require higher octane fuels. It's what I'm doing with my truck right now, I get better than premium grade fuel at less than mid-grade cost, even when the reduced fuel economy is factored in. Plus I can say I put "E85" in my tank, so I can use an AFV parking spot :)

Submission + - Microsoft can remotly kill purchased apps (pcmag.com)

Meshach writes: The terms of service for Microsoft's newly launched Windows Store allows the seller to remotely kill or remove access to a user's apps for security or legal reasons. The story also notes that MS states purchases are responsible for backing up the data that you store in apps that you acquire via the Windows Store, including content you upload using those apps. If the Windows Store, an app, or any content is changed or discontinued, your data could be deleted or you may not be able to retrieve data you have stored.

Submission + - Rats Feel Each Other's Pain (sciencemag.org) 1

sciencehabit writes: Empathy lets us feel another person's pain and drives us to help ease it. But is empathy a uniquely human trait? For decades researchers have debated whether nonhuman animals possess this attribute. Now a new study shows that rats will free a trapped cagemate in distress. The results mean that these rodents can be used to help determine the genetic and physiological underpinnings of empathy in people.

Submission + - Water Found on Mars (wired.com)

RCC42 writes: The opportunity rover has found evidence of liquid water once flowing on mars through the discovery of gypsum, a mineral that can only be formed in the presence of water.

Though other evidence in the past has suggested at highly acidic water on Mars, this is the first evidence for water with a pH suitable for life as we know it.

Submission + - Video Gamers Advancing Genetic Research (mcgill.ca)

An anonymous reader writes: From Mcgill's News Site: "Thousands of video game players have helped significantly advance our understanding of the genetic basis of diseases such as Alzheimer’s, diabetes and cancer over the past year. They are the users of a web-based video game developed by Dr. Jérôme Waldispuhl of the McGill School of Computer Science and collaborator Mathieu Blanchette. Phylo is designed to allow casual game players to contribute to scientific research by arranging multiple sequences of coloured blocks that represent human DNA. By looking at the similarities and differences between these DNA sequences, scientists are able to gain new insight into a variety of genetically-based diseases."

Submission + - Gas Powered Fuel Cell To Fix Electric-Car Range An (greencarreports.com)

thecarchik writes: While electric-car advocates may avoid the issue, some buyers simply won't choose a plug-in car that can't travel unlimited distances. That's where the Chevy Volt-style range extender comes in, though the Volt adds unlimited range by burning gasoline in a conventional engine to generate electric power.

Now a new type of fuel cell offers the potential for a different kind of range extender, one that removes the enormous practical problem facing hydrogen fuel cells: the lack of a distribution infrastructure to fuel vehicles that require pure hydrogen to feed their fuel cells.
Researchers at the University of Maryland have managed to shrink the size and lower the operating temperature of a solid-oxide fuel cell by a factor of 10, meaning it could conceivably produce as much power as a car engine but occupy less space.

The advances come from new materials for the solid electrolyte, as well as design changes, and the researchers feel they have further avenues for improvement left to explore.
