What did the expert fossil-poop hunter say to the trainee?

"Leave no stone unturd, son."

However, the orchid mantis has a full flowery disguise, complete with legs shaped like petals, that is convincing enough for scientists to suggest this hunter not only uses the masquerade to hide from prey, but also to attract victims. Examples of such aggressive mimicry have been seen before in the wild; for instance, one species of [URL="http://www.livescience.com/22122-types-of-spiders.html"][COLOR=#0066cc]bolas spider[/COLOR][/URL] is known to attract male moths by imitating female moth [URL="http://www.livescience.com/40136-storms-quell-insect-sex.html"][COLOR=#0066cc]sex pheromones[/COLOR][/URL].

A comment:

[QUOTE=davar55;360449]re: the second article above.

If the presence of a photon can be determined definitively,
without any loss of information, perhaps the uncertainty
principle is questionable. Measurement of the properties
of the smallest particles may just be a technological issue
and not a fundamental scientific limitation. Perhaps Planck's
"constant" may be based on the limits of current technology,
not on an absolute value determined theoretiically.[/QUOTE]

[QUOTE=xilman;360456]I'm quite prepared to believe that if you can provide supporting evidence.

Your prediction of the spectrum of radiation from an object in thermal equilibrium with its e-m radiation would be of interest.[/QUOTE]

I have no physical or experimental evidence that Planck's "constant"
may be a technologically-based variable (always gettijg smaller as
technology progressively improves), but I regard it as plausuble
simply on a philosophically based position that as humanity's
knowledge grows, the UP limitation would eventually be superceeded.

As to the second part, I suppose you're asking for the black-body
radiaion spectrum based on something non-standard that I've
suggested, but I don't know what. NBAQT (not-being a quantum
theorist) (of the original kind) I need another hint.

Since we all need more dinosaur-poop-related material:

But instead of neatly clarifying human evolution, the finding is adding new mysteries. * In a paper in the journal Nature, scientists reported Wednesday that they had retrieved ancient human DNA from a fossil dating back about 400,000 years, shattering the previous record of 100,000 years.The fossil, a thigh bone found in Spain, had previously seemed to many experts to belong to a forerunner of Neanderthals. But its DNA tells a very different story. It most closely resembles DNA from an enigmatic lineage of humans known as Denisovans. Until now, Denisovans were known only from DNA retrieved from 80,000-year-old remains in Siberia, 4,000 miles east of where the new DNA was found.The mismatch between the anatomical and genetic evidence surprised the scientists, who are now rethinking human evolution over the past few hundred thousand years. It is possible, for example, that there are many extinct human populations that scientists have yet to discover. They might have interbred, swapping DNA. Scientists hope that further studies of extremely ancient human DNA will clarify the mystery.“Right now, we’ve basically generated a big question mark,” said Matthias Meyer, a geneticist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and a co-author of the new study.

There were just two, Humberto and Ingrid, and both were relatively wimpy, Category 1 storms. That made the 2013 Atlantic hurricane season, which ended Saturday, the least active in more than 30 years — for reasons that remain puzzling.[/i]
[quote]The season, from June through November, has an average of 12 tropical storms, of which six to seven grow to hurricane strength with sustained winds of 74 mph or greater. Typically, two storms become “major” hurricanes, Category 3 or stronger, with sustained winds of at least 111 mph.

In 2013, there were 13 tropical storms, a typical number, but for the first time since 1994 there were no major tempests in the Atlantic. The last time there were only two hurricanes was 1982.

The quiet year is an outlier, however, in the recent history of Atlantic cyclones. The National Oceanic and Atmospheric Administration notes that 2013 was only the third calmer-than-average year since 1995.

The most intense storms this year had maximum sustained winds of only about 86 mph. Phil Klotzbach, a researcher at Colorado State University, said that is the weakest maximum intensity for a hurricane during a season since 1968. The first hurricane, Humberto, was just hours from matching the record for the latest first hurricane, Sept. 11.

In terms of accumulated cyclone energy, or ACE, the seasonal total stands at 31.1, the lowest since 1983 and just 30 percent of average. Looking back to 1950, only four other years had lower ACE totals: 1972, 1977, 1982 and 1983. (ACE is the sum of the squares of all of the storms’ peak wind speeds at six-hour intervals, and a good measure of a storm season’s overall power.)

To put that in perspective, Hurricane Igor (2010) alone racked up about 140 percent of this season’s total.

High expectations
[/b]
Heading into the hurricane season, all signs pointed toward a very active one. Forecast teams predicted seven to nine hurricanes, with higher-than-average ACE. Only the European Center for Medium-Range Weather Forecasting predicted about 80 percent of average ACE, but it still said there would be six or seven hurricanes.

The accuracy of groups that issue periodic mid-season updates and forecasts was not any better. The core months of August, September and October saw only minimal activity, despite key factors continuing to appear favorable for hurricanes.

While such an inactive season is not unprecedented, forecasters usually do a creditable job of predicting one.[/quote]
Since the hype-addicted MSM are only too happy to invoke global warming whenever there is a powerful hurricane or above-normal season, we need some suitable MSM-style stupid spin for the above story. I'm leaning toward one of the following two angles:

o [i]Dud of a hurricane season casts doubts on global warming[/i]

o [i]Below-normal hurricane season blamed on hints of Fed tapering[/i]

Time for a marketing survey to determine which stupid-spin generates the most social-media buzz from those-not-entitled-to-their-own-opinions...

Some of them must be really clueless. I type faster than 70 wpm, and I could tell you where every key is by memory.
