Submission + - World has only until 2030 to stem catastrophic climate change (cnn.com)

Camembert writes: CNN and other sources summarise the highlights of the just released VN report on global warming, and it looks dire. In essence we need to take immediate and substantial action, both on cutting CO2 and on active countermeasures, to keep further global warming in check, with disastrous results (famine, droughts, exponential heating) if we don’t.
I read elsewhere about possible active countermeasures, often the scale of the challenge may make them difficult to realise. Simpler options like massive tree planting (twice the size of India!) or planting of specific quick growing grasses seem more feasible yet also have challenges.

Comment Customer journey ? My ass (Score 3) 110

"Customer journey" is one of those horrible words thought out by marketing drones in expensive suits. When I'm a customer, I don't go on a fucking journey (if I want to journey, I'll take my luggage and go travel); companies have customer treatment, which can be good or poor, and that's it, fucking period.

Comment Anti-inflammants (Score 1) 183

I've probably got a benign from of Crohn, and have always refused any invasive measure or method of diagnostic, exactly in order to avoid risking what unfortunately happened to the author of TFA. I'm keeping it in check, more or less, with anti-inflammants and some care in my diet. Not ideal, and I know it may be progressing, but then again.. I'm 51. I'll sit out the ride until I die.
  For the rest, I'd not be too anxious about the thing. If your gut doesn't protest, you may possibly be best off by leaving it where it is. In any case: all the best !

Comment Re:Billion? (Score 2) 203

If I have a discussion with, say, a non-techie on, say, power usages, and most of the figures we quote are of the order of magnitude of some hundreds of kiloWatts, then it makes perfect sense to treat an outlier as several thousand kiloWatts, and not as a few Megawatts, it seems to me. An engineer would immediately folow me making a jump into Megawatts, a non-techie not necessarily so.

That is new to me. AFAIK it could be any of the queens. But I may be referring to outdated knowledge on Apis mellifera.

Seeing a swarming event actually happen is, indeed, awesome. Although I have no bees now because of my way of life, last summer a swarm temporarily settled in a tree close the veranda windows of my house - the buzzing ! - and stayed there over night (a sweet, warm summer night, they'd chosen their moment well). Next morning they were gone, and I still hope they're doing OK for themselves.

Son of a beekeeper here. All correct! Also, they have fairly intelligent swarming behaviour. When times are "economically" good, the sexless worker bees charged with feeding the queen will begin feeding certain larvae the special queen food, so these larvae - instead of becoming sexless workers - become queens. One of the new queens will then take part of the swarm with her (sometimes it will be the old queen btw). Individual bees decide on joining or not joining the outgoing swarm. We know they have a decision mechanism involving criteria - we simply don't understand the mechanism yet. Bees are fascinating.

Comment Disheartening (Score 5, Insightful) 164

OP here. Obviously, my submission had the bad luck of making it to the Slashdot front page simultaneously with the US presidential elections and their unexpected outcome. Yet I am appalled, truly appalled and disgusted, at what ACs have posted here (see above).

It is now clear to me that after many, many years there is nothing anymore for me on Slashdot. This is it. The level had gone down already for years. The repeated and increasingly vocal racism and vulgarity, the inanity, the name-calling, the bigotry - it had already been putting me off for a long time. Yet I had hoped that, at least for such momentous scientific news as Verlinde's theory, there could have been a discussion worthy of that name.

Slashdot's latest acquirer has done a prolly valiant job to try and turn things around, an effort before which I flourish my hat. It is clear to me, however, that it was too little and too late. I'm leaving slashdot. I will keep reading submissions as an anonymous reader, and that's it. So long, Slashdot !

Submission + - Groundbreaking Paper on arXiv derives Gravity from Holographic Principle (arxiv.org)

vikingpower writes: Dutch prodigy and Amsterdam University Professor Erik Verlinde published a paper on arXiv, yesterday November 7, titled "Emergent Gravity and the Dark Universe". In the paper, Verlinde derives gravity from the so-called Holographic Principle, which — simply put — states that gravity emerges from the interplay between and entropy re-arrangement of sub-atomic "strings" that live in a negatively curved space-time. At that level, "...spacetime and gravity are emergent from an underlying microscopic description in which they have no a priori meaning" . Most importantly, Verlinde's paper has as a consequence that Dark Matter, nemesis of many an astronomer, is nothing more than an illusion. Verlinde, who was awarded the Dutch national Spinoza science prize in the recent past, already completed the tour de force of deriving Newtonian gravity from the same principles in a 2010 paper, also on arXiv. We are probably looking at Nobel-prize material here, as Verlinde is acknowledged by his peers to "go one better than Einstein's General Theory of Relativity".
