[QUOTE]Prometheus (recorded as WPN-114) was the oldest known non-clonal organism, a Great Basin bristlecone pine (Pinus longaeva) tree growing near the tree line on Wheeler Peak in eastern Nevada, United States. The tree, which was at least 4862 years old and possibly more than 5000, was cut down in 1964 by a graduate student and United States Forest Service personnel for research purposes.[1] The people involved did not know of its world-record age before the cutting (see below), but the circumstances and decision-making process remain controversial; not all the facts are agreed upon by all involved.[/QUOTE]

Sandisk negotiating sale to Western Digital
 
[URL="http://www.bloomberg.com/news/articles/2015-10-19/sandisk-said-to-be-in-advanced-talks-to-sell-to-western-digital"]Potential storage merger[/URL]
[QUOTE]
SanDisk Corp. is in advanced talks to sell itself to Western Digital Corp., and the two storage makers could reach a deal as soon as this week, people with knowledge of the matter said.

Western Digital is discussing a price of between $80 and $90 per SanDisk share, according to two of the people, who asked not to be identified because the information is private. The company is leaning toward an all-cash offer, three people said. SanDisk closed at $72 in New York trading on Monday. While no agreement has been signed and talks could still fall apart, negotiations accelerated over the weekend, the people said.

Re. "Stark Beauty of Supersonic Shock Waves" - well, a subsonic shock wave, that would *really* be a novelty.

But yeah, Schlieren photos of shocks and animated computer simulations of shock/solid-object interactions ... very cool.

I only looked to the last 2, no free time, but I promise I will visit the others.
The one about bees is stupid, the conclusion is forced, and "political". Bumble bees are niche feeders, they feed from deep flowers because there is less competition there, the shallow flowers have many other "predators" feeding on them. And feeding from deep flowers makes their tongue longer, their body stronger (to get inside of flowers). In fact the article [U]does[/U] point about species which evolved in tandem, like that. But now, if their tongue became shorter in the last years (and I don't contest the results and work of the authors, I only contest the conclusion, nowadays even when I go pee on the urinal, that is an effect of "global warning") it is because they find plenty of easy to pick food, exactly contrary to what the article says, and they don't need to dig hard into the deepest flowers to get their nectar. Why they find plenty of food, that is a different story, it can be that there are more flowers, or that the competitors died (well... effect or not, of the climate change, etc.). But the conclusion the article draw shows that the biologists who wrote the study didn't really understand how evolution works (adaptation, more exactly), or they got some material support to write that conclusion.

OTOH, the last essay about the speed of light is very nice, I liked that.

Man died with 'tapeworm tumours'
 
[URL="http://www.bbc.com/news/health-34721419"]This is the second tapeworm story[/URL] I have encountered today. :ick:

[QUOTE]A man has died with tumours made of cancerous parasitic worm tissue growing in his organs, doctors report.
The patient had HIV and his weakened immune system allowed the worm-cancer to flourish.
The unusual case was diagnosed through a collaboration between the US Centers for Disease Control and the UK's Natural History Museum.
Doctors said the case, detailed [URL="http://www.nejm.org/doi/full/10.1056/NEJMoa1505892"]in the New England Journal of Medicine[/URL], was "crazy" and unusual.
[/QUOTE][URL="http://www.theguardian.com/us-news/2015/nov/04/california-man-tapeworm-brain"]This is the first[/URL].
[QUOTE]When the headaches first started in late August, Luís Ortíz tried to ignore them.
But after a day spent skateboarding in early September, the 26-year-old university student found the pain had become too much to bear.
Ortíz became disoriented, and when he started vomiting his mother rushed him to the hospital, where neurosurgeon Soren Singel found the real culprit: a tapeworm larva lodged in his brain. Worse, it had embedded itself in a cyst that was stemming the flow of water to his brain, Singel told the [URL="http://napavalleyregister.com/news/local/napa-man-survives-brain-worm/article_cbb075b1-e1f6-550f-97fc-f61645eedd6d.html"]Napa Valley Register[/URL].
Singel drilled a hole above Ortiz’s eyebrow and fished out the worm and the cyst with a neuroendoscope equipped with a grasping tool. “The worm was still wiggling when we pulled it out,” Singel told the Register.
