Submission + - 2 Futures Can Explain Time's Mysterious Past (scientificamerican.com)

cyberspittle writes: Tentative new work from Julian Barbour of the University of Oxford, Tim Koslowski of the University of New Brunswick and Flavio Mercati of the Perimeter Institute for Theoretical Physics suggests that perhaps the arrow of time doesn’t really require a fine-tuned, low-entropy initial state at all but is instead the inevitable product of the fundamental laws of physics. Barbour and his colleagues argue that it is gravity, rather than thermodynamics, that draws the bowstring to let time’s arrow fly. Their findings were published in October in Physical Review Letters.

I never tried to mold my daughter, but I also made sure that opportunities for science and technology were there for her. There were numerous signs along the way that she was headed in the direction of the sciences. She's always been interested in critters - We used to go to the Maine seashore, and one of our big activies there was exploring tide-pools. She "adopted" woolie bears in our front yard one fall, building villages for them. When she was in 5th grade, I read "The Hot Zone" with her. For years after she kept a picture of the ebola virus on the wall of her room, and we still trade ebola news over a decade later.

She got her bachelor's and master's degree in biological sciences, and started her PhD. About a year in, she discovered that she really didn't like the life sacrifices of the PhD lifestyle required, especially of a woman. She also realized that she likes the outreach side of science more - bringing science to students and others. She's managed to find a job in that field, while her husband continues to work on his PhD.

She's one terriffic daughter and person.

Earth has been advertising itself for more like a half-billion years. An atmosphere with free oxygen is rare, at least we haven't found one yet out of the explanets we've discovered. To be sure, we haven't studied the atmosphere on very many, but at the very least we know how to do so, at least for some.

There has been some suggestion of merely chemical processes that can give rise to free oxygen in the atmosphere, but I don't know how likely (or un) those processes are, and whether they cause the levels the Earth has, especially with traces of methane present at the same time.

We know our atmosphere has been biosculpted, and that would be something others could have seen for half a billion years.

One must assume that any alien civilization capable of interstellar travel would know at least as much as we do about the relevant technologies. That would include something Keplar-like, only better. You don't want to take your first interstellar steps to a place with no relevant planets.

Submission + - A Unique World-Wide Collaboration Around an Open Source Offline Password Keeper (indiegogo.com)

swv3752 writes: Introducing the Mooltipass, a physical encrypted password keeper that remembers your credentials so you don't have to. With this device, you can generate and safely store long and complex passwords unique to each website you use. A personal PIN-locked smartcard allows the decryption of your credentials and ensures that only you have access to them. Simply visit a website and the device will ask for your confirmation to enter your credentials when login is required.

Over thirty people from all around the globe contributed to bring this project to where it is now, including software and firmware engineers, designers, mechanical engineers, artists, project managers, students and security engineers. Our project started a year ago with a call for feedback and contributors. It turned out that people were thrilled by the idea of an open source password keeper and didn't hesitate to commit some (if not all!) of their personal time to join this adventure. Now there is three days left to finish funding.

Submission + - Big Banks Will Vie For Your Attention With Cardless ATMs and VR

tedlistens writes: In the year that bitcoin began to grow up and Apple Pay was born—and massive cyberattacks—the country’s largest financial institutions want you to imagine themselves as incubators. Three of the big banks opened up innovation labs to imagine what’s next in mobile banking; some are starting their own accelerators. Meanwhile, the latest research estimates that U.S. mobile payments, currently at $3.7 billion, will grow to $142 billion within five years. Now an industry not exactly known for speed is approaching 2015 with an ethos that sounds more Silicon Valley than Wall Street, touting visions of fridges that shop for you, Google Glass and Oculus Rifts, and the kind of futuristic security they hope will inspire consumers to trust them and their technology in the first place.

I can maybe see the life evolving in one of these solar systems after it leaves the black hole area, presuming the atmospheres of planets aren't scoured away by high-speed interactions with the interstellar medium.

However, how could this life "spread"? I don't see how you slow down any complex molecules from these speeds without totally incinerating them.
