Bigger Is Better (& Smarter)
When it comes to estimating the intelligence of various animal species, it may be as simple measuring overall brain size. In fact, making corrections for a species' body size may be a mistake."It's long been known that species with larger body sizes generally have larger brains," said Robert Deaner. "Scientists have generally assumed that this pattern occurs because larger animals require larger nervous systems to coordinate their larger bodies. But our results suggest a simpler reason: larger species are typically smarter."
Deaner said the findings imply that a re-evaluation may be in order for many previous studies that have compared brain size across different animal species, including ancestral hominids.
The new results showed that some primate species consistently outperform others across a broad range of cognitive tasks. It compared how well eight different brain size measures predicted the domain-general cognition variable generated in the earlier study. To the researchers' surprise, overall brain size and overall neocortex size proved to be good predictors, but the various measures that controlled for body size did not. The results did not change even when various statistical assumptions were altered.
Another unexpected finding was that the overall size of the whole brain proved to be just as good a predictor of intelligence as was the overall size of the neocortex. Scientists making cross-species comparisons have often assumed that the neocortex would be more closely linked to intelligence, since it is considered the "thinking part" of the brain. link

Why Mothra Doesn’t Exist
In the paper the researchers report on experiments performed on a Swedish population of the Speckled Wood Butterfly, Pararge aegeria. They show that large females lay more eggs than smaller females if they are allowed to lay eggs throughout each day, but in a situation where only part of the day was suitable for egg-laying the size of the female did not matter for the number of eggs laid.
This exercise suggests that growing to a much larger size typically doesn’t pay off in more eggs laid, and the optimal female size predicted by the model is relatively close to what is actually observed.
The paper concludes that one important reason why insects with a high capacity of larval growth do not evolve towards larger sizes may be that the fecundity [# of offspring produced] benefit is in fact relatively limited under natural conditions.

Atlantis Destroyed By Giant Tsunami
A group of scientists have uncovered new evidence that the island of Crete was hit by a massive tsunami at the same time that Minoan culture disappeared.
Until about 3,500 years ago, a spectacular ancient civilisation was flourishing in the Eastern Mediterranean. The ancient Minoans were building palaces, paved streets and sewers, while most Europeans were still living in primitive huts.
But around 1500BC the people who spawned the myths of the Minotaur and the Labyrinth abruptly disappeared. Now the mystery of their cataclysmic end may finally have been solved.
"The geo-archaeological deposits contain a number of distinct tsunami signatures," says Dutch-born geologist Professor Hendrik Bruins of the Ben-Gurion University of the Negev in Israel.
"The latter can only have been scooped up from the sea-bed by one mechanism - a powerful tsunami, dumping all these materials together in a destructive swoop," says Professor Bruins. The deposits are up to seven metres above sea level, well above the normal reach of storm waves.
"An event of ferocious force hit the coast of Crete and this wasn't just a Mediterranean storm," says Professor Bruins. Link

Born This Day: Immanuel Kant
Kant was a German philosopher, trained as a mathematician and physicist, who published his General History of Nature and theory of the Heavens in 1755. This physical view of the universe contained three anticipations of importance to astronomers;
2. He described the Milky Way as a lens-shaped collection of stars that represented only one of many "island universes," later shown by Herschel.
3. He suggested that friction from tides slowed the rotation of the earth, which was confirmed a century later. In 1770 he became a professor of mathematics, but turned to metaphysics and logic in 1797, the field in which he is best known. link

Medusa's Deep Sea Vent
The researchers picked that name to highlight the presence of a pink form of the jellyfish order Stauromedusae as well as numerous spiky tubeworm casings that festoon the vent chimney and bring to mind "the serpent-haired Medusa of Greek myth," said expedition leader Emily Klein.
"It's astonishing that a rich ecology thrives in these extreme environments," Klein added. She noted, however, that while all the organisms near vents are adapted to the high pressures at these depths, not all experience extremely high temperatures.
"The temperature of the ocean floor is about 2 C and there is a strong temperature gradient as you move away from the vent, so animals living a few inches away may experience temperatures only a few degrees above normal for the ocean floor."
"Despite the great tempeature of the vent water, it doesn't boil until 390 C because pressures on the ocean floor are so great, about 200 times the pressure at sea level," Klein said. The tremendous pressures result from the weight of almost two miles of seawater pressing down from above. link

Colours Out of Time & Space
Cover by Pete Von Sholly
On Earth, Kiang and colleagues surveyed light absorbed and reflected by plants and some bacteria during photosynthesis, a process by which plants use energy from sunlight to produce sugar. Organisms that live in different light environments absorb the light colors that are most available. For example, there is a type of bacteria that inhabit murky waters where there is little visible light, and so they use infrared radiation during photosynthesis.
According to scientists, the Sun has a specific distribution of colors of light, emitting more of some colors than others. Gases in Earth's air also filter sunlight, absorbing different colors. As a result, more red light particles reach Earth's surface than blue or green light particles, so plants use red light for photosynthesis. There is plenty of light for land plants, so they do not need to use extra green light. But not all stars have the same distribution of light colors as our Sun. Study scientists say they now realize that photosynthesis on extrasolar planets will not necessarily look the same as on Earth.
"It makes one appreciate how life on Earth is so intimately adapted to the special qualities of our home planet and Sun," said Kiang. link

The Why of Fly Flying
The researchers also found that searching is intermittent, such that flies actively search by making tight turns, and fly straight some distance to begin searching again. Scale-free movement patterns have been found in diverse animals including zooplankton, wandering albatrosses, jackals, and even human hunter-gathers. Intermittent searchers include octopi, graylings, and mating crickets.
Andy Reynolds says, "Our results with freely flying Drosophila appear to be the first reported example of searching behaviour that is both scale-free and intermittent. This suggests that these behaviours are not part of two different searching strategies, but rather represent a single very effective and perhaps widely adopted strategy." link

Irrational Fashion Changes Explained
Perhaps not surprisingly, the study also found that the more trendsetting innovators there are in a society, the faster one trend will replace another within a particular sector. “Innovators are the cool ones who ‘pump’ new fashions into our world,” Bentley said. The results suggests that the practice, common among captains of the fashion industry, of trying to handpick the next consumer “gems” amongst millions of proposals is a hopeless undertaking.
Regular rates of popular culture change reflect random copying. 2007. R.A. Bentley, et al. Evolution and Human Behavior, published online 17 January 2007.

Born This Day: Surf Board Pioneer
Early surfboard designs consisted of solid wooden boards dating back to the ancient Hawaiians, these new-concept, lighter boards were an immediate success and became extremely important in the evolution of the modern surfboard. In the 1930's he made the first major design advancement with the invention of fins. Before this, a surfer had to use his back foot to make the board turn. link Images © Rick Griffin
Journey To The Center of The Sinkhole
The system’s unusual hydrothermal nature is analogous to liquid oceans under the icy surface of Jupiter’s moon Europa. Technology developed to explore the sinkholes could be applied to future space probes of Europa, where scientists believe that deep cracks and holes in the ice offer a chance of finding extraterrestrial life.
Microbes which appear to be new to science have been discovered floating in deep water and lining rocks in ZacatĂłn. Far below sunlight’s ability to penetrate, they may get their energy from nutrients welling up from hot springs. Gary and others speculate that previously undocumented life may await discovery in the murky depths.
Unique in the world of robotic explorers, DEPTHX is autonomous. The probe does not rely on instructions from humans to decide where to go or what to do. It creates 3D maps of previously unexplored areas as it swims along and then uses those same maps to navigate back to the surface.
Doctoral student Marcus Gary SCUBA dives with the DEPTHX probe during initial in-water tests at The University of Texas at Austin Applied Research Laboratories wet test facility.Cenote ZacatĂłn first achieved notoriety when two divers attempted to reach the bottom in 1994. One of them, Sheck Exley, died in the attempt. The other, Jim Bowden, survived, descending to a record depth of 925 feet. The outcome caused scientists to rethink ways that ZacatĂłn could be explored safely. link

Watching The Brain See The Future
Scientists can now "read" a person’s intentions from their brain activity. This is made possible by a new combination of functional magnetic resonance imaging and sophisticated computer algorithms. The researchers were able to recognize the subjects intentions with 70% accuracy based alone on their brain activity - even before the participants had seen the numbers and had started to perform the calculation.
In the future it will be possible to read even abstract thoughts and intentions out of a person’s brain.
Brain regions from which it was possible to "read out" peoples' intentions. In specific regions fine-grained patterns of brain activity showed slight differences depending on whether a person was preparing to perform an addition or a subtraction. From activity patterns in the green regions it was possible to read out covert intentions before subjects began to perform the calculation. From the regions marked in red it was possible to read out intentions that were already being acted upon.Ref.: Reading hidden intentions in the human brain. 2007. John-Dylan Haynes, et al.

Empire State Humans
Since I was very young I've realised
I never wanted to be human size
So I avoid the crowds and traffic jams
They just remind me of how small I am
Because of this longing in my heart
I'm going to start the growing art
I'm going to grow now and never stop
Think like a mountain, grow to the top
Tall, tall, tall, I want to be tall, tall, tall
As big as a wall, wall, wall,
as big as a wall, wall, wall
And if I'm not tall, tall, tall,
then I will crawl, crawl, crawl
Because I'm not tall, tall, tall, tall, tall, tall, tall
With concentration
My size increased
And now I'm fourteen stories high
At least
Empire State Human
Just a bored kid
I'll go to Egypt to be
The pyramids
Brick by brick
Stone by stone:
Growing till he's fully grown
Fetch more water
Fetch more sand
Biggest person in the land

UFOs Key To Global Warming
From The Ottawa Citizen:
Paul Hellyer, 83, is calling for a public disclosure of alien technology obtained during alleged UFO crashes -- such as the mysterious 1947 incident in Roswell, New Mexico -- because he believes alien species can provide humanity with a viable alternative to fossil fuels.
Mr. Hellyer has been a public UFO advocate since September 2005 when he spoke at a symposium in Toronto. But with concern over global warming at an all-time high, and Canadian political parties struggling to out-green one another, Mr. Hellyer said governments and the military have a responsibility to "come clean on what they know" now more than ever.
"Climate change is the No. 1 problem facing the world today," he said. "I'm not discouraging anyone from being green conscious, but I would like to see what (alien) technology there might be that could eliminate the burning of fossil fuels within a generation ... that could be a way to save our planet."
