Egyptian Aisha Mustafa, 19, has dazzled the physics world with a new invention that could launch spacecraft off the Earth’s surface and soaring through space without any fuel. Space is filled with a billowing sea of quantum particles that jump in and out of existence, and Aisha Mustafa proposes using thin silicon panels, spaced closely together, to trap these particles and then move against them, creating a propelling force. This innovation would make space exploration lighter, safer and cheaper than the traditional “blast off” method. Mustafa still has some design work to do, but unfortunately her research is currently limited by lack of state funding for space science departments at the university level, though her school’s science club did help fund her application for a patent.
What a woman.
nah lies all oppression
And speaking of bad ass lady scientists.
Oooh, sailing to the stars on a sea of quantum foam? Space travel hasn’t been this romantic since the lumeniferous aether was exploded!
Timekeeping on Mars is a bit like telling time on Earth, because the planets are similar in lots of ways. To start with, the Martian day, or sol, is 39 minutes and 35 seconds longer than a day on Earth. This isn’t a lot, but it adds up quickly when you’re living on Mars time—as the Curiosity team will. And a Martian year lasts 668.59 sols, about 1.88 times an Earth year. Seasons last much longer and are much more extreme, thanks in part to Mars’ deeply eccentric orbit.
“It feels like you are perpetually flying east 40 minutes every day,” said Deborah Bass, a scientist at JPL who worked on the Spirit and Opportunity rovers and the Phoenix lander. “You’re always jet-lagged. It’s only a little bit, because an hour — who cares, that’s not so bad. But it starts to take its toll.”
I kind of feel like living on Mars would be the solution to all of my problems.
I’ve spent a lot of time there over the last few years, and believe me, it’s not a quiet neighborhood. :)
Ah, but I’d put up with SO MUCH ruckus for an extra 40 minutes in every day and an extra 10 months in every year…

Daughters tie loved ones closer together and encourage them to communicate their emotions more effectively, the researchers believe.
Prof Tony Cassidy, from the University of Ulster, who carried out the study with researchers from De Montfort University in Leicester, said that having a sister helped to promote good mental health.
He said: “Sisters appear to encourage more open communication and cohesion in families. However, brothers seem to have the alternative effect. Emotional expression is fundamental to good psychological health and having sisters promotes this in families.”
Girls who had sisters also tended to be more independent and keen on achievement, according to the findings.
Having a sister makes you happier and more optimistic, say psychologists - Telegraph
Interesting but not surprising. Also, I call bullshit on the theory that boys are just naturally less likely to talk about things.
We analyse the results of our experimental laboratory approximation of motorways networks with slime mould Physarum polycephalum. Motorway networks of fourteen geographical areas are considered: Australia, Africa, Belgium, Brazil, Canada, China, Germany, Iberia, Italy, Malaysia, Mexico, The Netherlands, UK, USA. For each geographical entity we represented major urban areas by oat flakes and inoculated the slime mould in a capital. After slime mould spanned all urban areas with a network of its protoplasmic tubes we extracted a generalised Physarum graph from the network and compared the graphs with an abstract motorway graph using most common measures. The measures employed are the number of independent cycles, cohesion, shortest paths lengths, diameter, the Harary index and the Randic index. We obtained a series of intriguing results, and found that the slime mould approximates best of all the motorway graphs of Belgium, Canada and China, and that for all entities studied the best match between Physarum and motorway graphs is detected by the Randic index (molecular branching index).
I studied Ray Kurzweil, who invented the robot in the piano. He talks about how in 2024 there’ll be a point in time where you won’t be able to differentiate a computer from a human. There’s going to be a point in time where the android is going to be the other; homosexuals were the other, black people were the other, and the android will be the other. Man has to build these robots because man has to be in control.
Also, I think androids are sexy.

I completely believe everything she says here. Except for the bit about androids being sexy, because that just depends on the android, ya know?
