If we have done away -like postmodernism- with the notion of absolute truth, and we are living in a life-world where observers with limited knowledge try to 'make sense' of their envirnoment, then we we have certain freedom to define other forms of truth.

Arctic Ice March 2011 Update #2


The melt season of 2010 ended with a low extent and with little ice older than two years. There are strong indications that the winter of 2010 - 2011 did not compact and thicken the sea ice as much as would normally be expected.

Arctic sea ice extent averaged over December 2010 was 12.00 million square kilometers (4.63 million square miles). This is the lowest December ice extent recorded in satellite observations from 1979 to 2010, 270,000 square kilometers (104,000 square miles) below the previous record low of 12.27 million square kilometers (4.74 million square miles) set in 2006 and 1.35 million square kilometers (521,000 square miles) below the 1979 to 2000 average.

Researchers have discovered a 525-million-year-old fossil which belongs to a group of tentacle-bearing creatures which lived inside hard tubes. 

The creature belongs to a group called pterobranch hemichordates which are related to starfish and sea urchins but also show some characteristics that offer clues to the evolution of the earliest vertebrates. About 30 species of pterobranch are known to exist today although 380-490 million years ago a group of these animals called graptolites were common across the prehistoric oceans.

Scientists are launching a three-pronged attack on one of the most obstinate puzzles in materials sciences: what is the pseudogap?

They used three complementary experimental approaches to investigate a single material, the high-temperature superconductor Pb-Bi2201 (lead bismuth strontium lanthanum copper-oxide). Their results are the strongest evidence yet that the pseudogap phase, a mysterious electronic state peculiar to high-temperature superconductors, is not a gradual transition to superconductivity in these materials, as some have long believed.

Instead, it is a distinct phase of matter.

The pseudogap mystery

The Clovis people, Paleo-Indians whose tools were known for their distinctive 'fluted' points, were once thought to be the original settlers of North America about 13,000 years ago.    The name originates not from the 5th century Frankish king but rather the town in New Mexico where the stone projectile points created by their distinctive percussion and pressure flaking techniques were first discovered.

The past few years have seen a decline in the percentage of Americans who believe what scientists say about climate science. 

The science community shares some of the blame, obviously; the IPCC made rookie errors in its recent assessment and even intentionally included non-science results as data, and the so-called "Climategate" emails showed scientists weren't always out to promote science as much as they were out to stick it to opponents, behavior just like every other field where humans work. 

We are developing past the merely human stage. We couldn’t stop it if we all really wanted to. Techno-future will be.

The transhumanism crowd has understood what evolution is all about while many other intellectuals still grapple with getting their head around mere old biological evolution. Evolution is true by tautology: Whatever there will be (successful, more numerous, …) in the future, will be there (successful, more numerous, …) in the future. This is the basis of what some call ‘algorithmic evolution’.

I think one of the first things that got me interested in evolutionary biology was finding out that whales used to have legs. It's pretty incredible that the sleek, powerful whales of modern day oceans had their origins in blundering land animals like cows and hippos. Nothing spoke more to me about the aeons of time that has passed than imagining generation after generation of whales tentatively playing with the water, feeding there, learning to become good swimmers, and eventually swimming in the open ocean amongst the fishes, their terrestrial history a long forgotten memory.

It's one of the most persistent problems in camouflage: how do you hide your eyes?

Skin is not that difficult to disguise. You can change its color, cover it up, match it to your environment. But eyes are tricky. You have to be able to see out of them. And unfortunately, predators are extremely good at looking for eyeballs.

I'm not a predator, but I am a marine biologist, which is kind of the same thing. I've done my time searching through plankton soup for squid larvae--and I can tell you the best way to search is to look for the eyes. They're just so recognizable!

Last month, an article that had caused something of a buzz in science circles since November was published in the journal Icarus.   John Matese and Daniel Whitmire, physicists at the University of Louisiana at Lafayette, wrote a paper(1) speculating about the existence of an unknown planet, a monstrous binary companion to our Sun bigger even than Jupiter.

The problem, other than the usual hype by places like Huffington Post along with mainstream media outlets, was this planet would have to be in the Öpik-Oort Cloud , which is itself a hypothesis.
