In terms of thermodynamics, you'd need a machine operating between 2 temperatures. The efficiency (and energy output) of your engine would depend on these temperatures. While in cold winter you could perhaps light your room, in summer it wouldn't give you a thing. I should remind you that in thermodynamics we calculate stuff (efficiencies) in Kelvin (not Celsius, so what even _is_ Fahrenheit?), so to operate a machine between 50ÂC and 25ÂC (~325K, 300K) isn't much worth all the trouble. For sure you couldn't have an eternal computer. Perhaps you could run 10 machines on normal power while 1 is driven by heat. I'd say that's technology for those room-sized mainframes of the whatever-year-i-wasn't-born.
Well, this's been a long long time. There was that whole revolution in cell physiology in the 70s. Now we're on the computational part.
The human genome is read, but still we need to figure out: given a sequence of letters (out of the four), what protein (3-D structure, function, reactive parts etc) is associated with it? How is it cut into introns and exons? What sequence of letters can act as regulators? (without such answers I find the human genome project pretty useless)
Still, a Nobel well awarded to Watson and Crick, I'd say.
There are detectors being built which use a different idea... a gravitational wave which enters the detector modifies the sizes of a 0.6m diameter ball of copper. This ball is in lifted position, all stable from outside vibration and supercooled (~20 mK). They detect the variation in size of the ball and say a grav wave came in.
A guy in Brazil wanted to build a detector like this (3m in height) for US$ 2million. Let's see what he can do with that... there would be hundred of those in the USA for that amount.
I don't recall if those filaments were also found in humans, but I think so. Small Fe3O4 magnetized filaments. Similiar to those described in a famous article by Blakemore (i read a review in a journal from 1996). Could be the practical effect of strong magnetic fields acting on those strains.

I thought this was last year... Or was there another meteor shower?
I actually thought the same thing. The Leonide shower is a yearly event due to dust located on earths track. Now some years ago a comet passed on this track and released new dust (much dust), so it was really spectacular last year or the year before. This happens every 33 years. In China people really observed a meteor thunderstorn, like 3600 meteors/h. I've seen some great long-exposition photos. (no, you don't call it a shot;-) )
This year you should expect to see far less meteors, much closer to the usual "background" levels. Still it could happen that some dust was left on the track or has re-arranged so it'll be there exactly when your country is at night. I was very unlucky when I tried to observe the shower - for I slept and only saw 2 - but my wishes came true: girlfriend and job... but it took some long time to fullfill. So good luck with the shower then.
Ironically, I think their forcasts are more accurate than our local guys
No irony, our weather depends on space weather, so you could expect that it's harder to predict our weather because it has more things interfering;-).
I was reading about old works on weather forecast (old=1963). Everybody who works on attractors after this year quotes this Lorenz (J. Atm. Sci., 1963)... Cute pictures.
Which leads me to a different point. People often try do describe earth's weather as a strange chaotic attractor, because so many things make it vary and because unprecise measurments may lead to very different results. I wonder if such thing is applyable to space forecasts...

This is a joke which is very common, but some might not have read it...
Q: Why do programmers often confuse Halloween and Xmas?
Let's see... I have a x-ray detector here which uses a beryllium window. Low atomic-number elements transmit a lot of x-ray. That's one problem.
I think charged particles from sun(alpha particles, for instance) are blocked by earth's magnetic field, so close to some planets there would be little problem. Now neutrons pass unaffected through the magnetic fields and need to be blocked otherwise. Lead would be a costful solution. But heavy elements absorb them best.
I didn't read about the age of the star, but if this is a young solar system and the "dust hasn't settled", then maybe it could harbour life in future. But so far dust is bombing the planet (so I understand was done the observation), I wouldn't take it as possible. But this seems like one of the best candidates...
And only 10 lightyears away... we still need that worm-hole technology, if there is such thing. Maybe we could ourselves settle on that planet, in the future.
For sure: bacterial life dominates 100% of earth's surface. Why should we pride about 83%?
It's like, bacterial life is everywhere. It is all around us. Even now, in this very room. You can see it when you look out your window or when you turn on your television. You can feel it when you go to work, when you go to church, when you pay your taxes. It's kinda like CowboyNeal...

never comes closer than 3.6 million miles to our planet
For 2002AA29 in particular, you can use link Keep in mind that the orbital solution is based on only a short arc: only 28 days, about one twelfth of a complete revolution. Our estimates of the orbital parameters -- and behavior -- could change quite a bit over the next few months.
Indeed the orbit needs correction. Take, for instance, July 10th, 2016. On the simulator pointed out in the parent you get a distance earth-asteroid of 0.018 AU=1580587 miles~=1,6 million miles, way less than the least predicted, as quoted in the article.
If you follow chaos theory, you easily estabilish that the initial values needs more precision.
I think Mars wasn't much warmer 3,5 Giga-years ago. The Herzsprung-Russel Diagram shows that a star in the main sequence (=the sun, for example) gets warmer as it ages until it reaches certain age (which we have not reached). I don't know if the temperature rise is really very significant, but over 3,5 GY it likely makes quite a big difference.
That's also why I like the hypothesis that life evolved on Venus (published couple o' days ago). When it arose (if it arose), the sun was quite colder and Venus wasn't that hot... more similar to earth.
Did they take in account the extra CO2 present in the atmosphere? I'd say that this improves a little the taste as well.

Ok, Jupiter really wins.
