+ - Fuel Free Spacecrafts Using Graphene

William Robinson writes: While using a laser to cut a sponge made of crumpled sheets of Graphene oxide, Researchers accidentally discovered that it can turn light into motion. As the laser cut into the material, it mysteriously propelled forward. Baffled, researchers investigated further. The Graphene material was put in a vacuum and again shot with a laser. Incredibly, the laser still pushed the sponge forward, and by as much as 40 centimeters. Researchers even got the Graphene to move by focusing ordinary sunlight on it with a lens.Though scientists are not sure why this happens, they are excited with new possibilities such as light propelled spacecraft that does not need fuel.

The MAME dev community has always been very up front that the MAME license has no attribution of rights to the ROMs themselves. The emulation code is there's and they can do anything they want with it. I have read elsewhere that emulation is perfectly legal (except when it comes to Macs for some reason) and so I don't see where publisher permissions are the least bit necessary.

Comment: Yes, let's INCREASE waste (Score 2) 270 270

Regular coffee pot + 1 coffee bean grinder + 1 lb bag of beans = 1 possibly recyclable / compostable bag plus a hundred + cups of coffee.

Keurig setup + 1 kcup insert = 1 cup of crappy coffee plus an unnecessary environmental impact in the form of an non-reusable cup.

Why in this day and age are we engineering waste INTO products when we should be engineering waste OUT of the product? It doesn't make sense.

Comment: The curriculum is crap (Score 1) 284 284

My son in 6th grade is doing the math work and it's just atrocious how badly basic multiplication has been mangled. For decades American kids learned math fundamentals by rote and we came out of those classes knowing exactly how to do it. Now the math problems are infrequently used such that there is no "drilling and killing" of any fundamental concepts. The whole thing sucks.

Comment: Money probably plays a perverse role (Score 1) 211 211

I'm a low-level manager at a great company as well. For leading a small team of analysts, this is probably not a bad place for me to be. However, I also find myself in need of a web developer who can bring database skills into the mix as well. Such talent will likely cost more salary than I am making, but other people such as my manager and the HR person are concerned that this is an unworkable situation. My response to this is a heartfelt "why?".

If the person bringing special talents to my team is worth x dollars on the general market, what possible difference should it make that he earns more than me in his particular role? My suspicion is that this attitude plays a huge role in attracting morons to ever more influence over other people to chase that dollar when what would be best for the company is for them to chase success in the form of individual contribution.

Comment: Intelligence != Research Skills != Knowledge (Score 1) 227 227

It sounds like intelligence is being used as a proxy for subject matter knowledge, and is being wrongly compared to research skills. Being smart enough to do research rather than throw your arms up in the air and saying "it can't be done" is an important feature of emotional intelligence. I think what the article means to say is that people think they are experts when they aren't. Too bad people writing about "intelligence" don't know how to write about it effectively.

Comment: A biological "race" condition? (Score 2) 96 96

My understanding of HIV is that when it infects human cells, it hijacks the tRNA (iirc) so that the human cells continue producing more HIV viruses. With the article describing synthetic antibodies binding to HIV, the virus is unable to infect human cells. So this would seem like a race condition where the antibody needs to get to the HIV *before* HIV has a chance to infect a human cell. How can this happen reliably?
