Not dead!
So let's return to basics. Via xkcd.

Here’s how things seem to stand. Entropy is increasing. London Bridge is falling down. The Second Law of Thermodynamics is a picture of the fall, and time is its measure. Gravity (and its evil twin, inertia) runs the clock. Particles without mass, such as photons, can’t be made into clocks (that is, structures that measure the passage of time) all by themselves, and as more and more material transforms into such massless particles, the material world degrades to low-level energy in fits and starts, fizzles and pops.But maybe there's hope! Read Gravity’s Punch: The Heat Death of the Universe Got You Down? Fight Back with Science!
All matter eventually becomes heat lugged outward in the form of force-carrying particles such as photons and, maybe, gravitons. Outward to where? To nowhere.
It’s a picture of the universe as one flaming arrow shot into the dark. The arrow hits no target because there is no target out there.
The expanding pressure is inexorable. The cosmological constant does not allow the universe to contract again. All the black holes evaporate. The coarse-grain irregularities of nature even out. Those force-carrying particles the bosons are all that remain and they spread until they are so far apart they can no longer cause any change in another portion of existence. Their world lines intersect nothing ahead. Without matter and causation, you can’t build a clock.
The clocks don’t stop, they simply cease to exist.
The universe dies.
Or lives on in an ineffectual forever, depending on how you want to look at it.

Using a powerful new camera on the Hubble Space Telescope, astronomers have discovered what appears to be the most distant object ever observed, a small proto galaxy some 13.2 billion light-years away that dates back to just 480 million years or so after the Big Bang birth of the universe.

'Chaplin Today: The Circus,' documentary by Francois Ede, Deleted 10-minute sequence 'October 7-13, 1926,' Outtakes from a week of shooting Three home movies from the archives of Lord Louis Mountbatten 'The Hollywood Premiere (1928),' Reportage on the L.A. premiere 'Camera A, Camera B,' shots made simultaneously from the two cameras used 3-D Test footage by Roland Totheroh Excerpts from 'Circus Day' with Jackie Coogan -- an adaptation of a favorite children's book Photo gallery, film posters, trailers, interactive menus, and scene access.One viewer of this extra material was a fellow named George Clarke, who is described as an "independent Irish documentary filmmaker." [We suspect this means he doesn't actually work a lot.] In looking at some of the footage, he thought he saw something odd: a random passerby, walking down the street, adopting the rather distinctive posture of . . . a person talking on a cell phone. So Clarke put together his own short documentary, so you can see for yourself:

Boys are slightly more likely to die in infancy than girls. To compensate, more boys are born than girls so there will be equal numbers of young men and women at puberty. In all societies that record births, between 103 and 106 boys are normally born for every 100 girls. The ratio has been so stable over time that it appears to be the natural order of things.From The Economist
That order has changed fundamentally in the past 25 years. In China the sex ratio for the generation born between 1985 and 1989 was 108, already just outside the natural range. For the generation born in 2000-04, it was 124 (ie, 124 boys were born in those years for every 100 girls). According to CASS the ratio today is 123 boys per 100 girls. These rates are biologically impossible without human intervention.
