Researchers Accidentally Discover How To Turn Off Skin Aging Gene

holmstar Re:increased risk of cancer? (170 comments)

Actually, it sounds like this enzyme increases the break-down of collagen, so decreasing it would tend to make it harder for cells to move around, but as others have said, would probably slow healing. Healing quickly would have been a big evolutionary advantage. Smooth skin in advanced age? Not so much.

AI Expert: AI Won't Exterminate Us -- It Will Empower Us

holmstar Re:programming (414 comments)

Let's say we assign an AI to find and execute a solution for the increasing levels of CO2 in the atmosphere and oceans. The AI may decide that humans are the primary impediment to achieving it's goals, and set out to clandestinely destroy human industrial capacity. Maybe it would hack into the control equipment and cause machines to destroy themselves. "Reduction in CO2 output achieved" -- satisfied AI.

Practical Magnetic Levitating Transmission Gear System Loses Its Teeth

holmstar Re:Smoothing out diesel Aircraft engines? (103 comments)

I wonder whether the magnetic coupler would be any lighter than a larger flywheel. Also, couldn't the slipping of the coupler set up harmonic vibrations in the prop as well? (I imagine a magnetic coupler would slip in a notch-y fashion.)

Practical Magnetic Levitating Transmission Gear System Loses Its Teeth

holmstar Re:Still need transmission in cars (103 comments)

I wonder how high speed electric trains are geared? Maybe they have more than one motor on the same axle, wound for different ranges of speed?

Practical Magnetic Levitating Transmission Gear System Loses Its Teeth

holmstar Re:Might be a fit for EVs (103 comments)

I agree on the unsprung mass issue, but I wonder if it would be possible to use a linear motor in place of a shock absorber to counter some of the negative handling effects. I doubt it would be able to make up for it completely, but I imagine it could help quite a bit.

Montana Lawmakers Propose 85 Mph Speed Limit On Interstates

holmstar Re:Here in Florida (525 comments)

If you can't feel the road at all, then that car probably has no business going faster than 80.

Montana Lawmakers Propose 85 Mph Speed Limit On Interstates

holmstar Re:Wildlife Fencing (525 comments)

Most highway fencing I've seen seems to be geared toward keeping cattle out (only about 4-5 feet tall). You would need something like an 8ft fence to have a chance at keeping deer out.

Montana Lawmakers Propose 85 Mph Speed Limit On Interstates

holmstar Re:Montana used to have no speed limit at all... (525 comments)

In the USA the police can pull you over for 1mph over the posted limit, but it's pretty darn rare. Generally 10mph over the limit on highways is ignored, though it will vary from place to place.

Ask Slashdot: Minimizing Oil and Gas Dependency In a Central European City?

holmstar Re:citation, please? (250 comments)

England gets stupendously cold? It routinely reached -28C last winter where I live. What would that be? "Ludicrously cold"? "Plaid"?

Ask Slashdot: Minimizing Oil and Gas Dependency In a Central European City?

holmstar Re:The number one thing (250 comments)

Pure water isn't run through the collector. They use a mix of water and glycol. It's also common to allow the fluid to empty out of the collector at night, to reduce heat loss.

Researchers At Brown University Shattered a Quantum Wave Function

holmstar "Is consciousness required?" (150 comments)

“No one is sure what actually constitutes a measurement. Perhaps physicists can agree that someone with a Ph.D. wearing a white coat sitting in the lab of a famous university can make measurements. But what about somebody who really isn’t sure what they are doing? Is consciousness required? We don’t really know.”

If so, you can just about guarantee that we're living in a simulation.

The "operational prototype" is a prototype commercial reactor. They plan to build 5 more research reactors, each within a year, before building a commercial prototype that they expect will take 5 years.

Conservative Groups Accuse FCC of Helping Net Neutrality Advocates File Comments

holmstar Re:Conservatives crying "no fair"? (283 comments)

For instance Democrats tend to like big companies with unionized workforces, and pushed through the GM bailout in the face of mostly Republican opposition. For more complicated reasons, the Democrats voted for the bank bailout, while most Republicans opposed it.

Don't kid yourself. The republicans opposed these bailouts because they knew that the democrats would be able to pass them anyway, and they can go to their constituents and say how bad the democrats are for supporting the bail-outs. Completely ignoring the fact that they would have done it as well, if there hadn't been enough democrats to pass it. Nobody, other than some of the tea party members, was going to let those bail-outs fail to pass.

Bucky balls nearly double lifespan in rats

holmstar holmstar writes  |  more than 2 years ago

holmstar (1388267) writes "Researchers at Université Paris Sud in France have discovered that bucky balls mixed with olive oil, when consumed along with a normal diet, extend the lifespan of rats from 22 months to 42 months. Olive oil without bucky balls extended life span only to 26 months."
