2012: Warmest Year on Record for U.S.
Last year “marked the warmest year on record for the contiguous United States,”the National Climatic Data Center just confirmed.The red dots are places that last year set records for average annual high temperatures.
This probably won’t surprise many, but “a record warm spring, second-warmest summer, fourth-warmest winter and a warmer-than-average autumn” combined to make the year’s average temperature 55.3°F.
That’s “3.2°F above the 20th century average, and 1.0°F above 1998, the previous warmest year.”
And 2012 was also “a historic year for extreme weather that included drought, wildfires, hurricanes and storms,” the data center points out. It notes, though, that “tornado activity was below average.”
The center’s “U.S. Climate Extremes Index” indicates that 2012 was “the second most extreme year on record for the nation. The index, which evaluates extremes in temperature and precipitation, as well as landfalling tropical cyclones, was nearly twice the average value and second only to 1998. … 2012 [saw] 11 disasters that have reached the $1 billion threshold in losses, to include Sandy, Isaac, and tornado outbreaks experienced in the Great Plains, Texas and Southeast/Ohio Valley.”
The Weather Channel notes that:
“October was the only cooler than average month in the Lower 48 states in 2012. March and July were the warmest such months on record, there. Four other months: January (4th warmest), April (3rd warmest), May (2nd warmest) and June (8th warmest) landed in the top 10 warmest respective months.”
And, the channel warns, “more dangerous weather is ahead.”

New Species of Bee Named After Sheldon From ‘The Big Bang Theory’ 

What do you do when you have to name a brand new species? Some opt for using some defining physical feature. Others use their own name. Andre Nemesio, from the Universidade Federal de Uberlândia, in Brazil, went for something a bit different: he and his team just named a brand new orchid bee Euglossa bazinga, after the catch phrase used by Sheldon Cooper on the television show “The Big Bang Theory.”

The paper describing the bee says:

The specific epithet honors the clever, funny, captivating “nerd” character Sheldon Cooper, brilliantly portrayed by the North American actor James Joseph “Jim” Parsons on the CBS TV show “The Big Bang Theory”. Sheldon Cooper’s favorite comic word “bazinga”, used by him when tricking somebody, was here chosen to represent the character. Euglossa bazinga sp. n. has tricked us for some time due to its similarity to E. ignita, what led us to use “bazinga”. Sheldon Cooper has also an asteroid named after him (246247 Sheldoncooper).

Orchid bees are a beautiful, but poorly understood type of bee, that collect all sorts of chemicals that they then use to attract females. These bees co-evolved with the plants they collect from, and the plants rely on the bees for pollination. Surprising Science covered research on that very evolution:

But a new study in Science has found that the relationship isn’t as equal as had been thought. The biologists reconstructed the complex evolutionary history of the plants and their pollinators, figuring out which bees pollinated which orchid species and analyzing the compounds collected by the bees. It seems that the orchids need the bees more than the bees need the flowers—the compounds produced by the orchids are only about 10 percent of the compounds collected by the bees. The bees collect far more of their “cologne” from other sources, such as tree resin, fungi and leaves.

Nemesio hopes that by naming the bees something recognizable, researchers can call attention to their rapidly deteriorating habitat. So far, he has described a dozen new species of orchid bees, naming two of them after Brazilian icons. He hopes that Sheldon’s catch phrase can make orchid bee research catchy as well.

Pandas’ Bamboo Food May Be Lost to Climate Change
Though they are one of the most beloved animal species on Earth, pandas aren’t safe from the devastating effects of climate change.
According to a new study, projected temperature increases in China over the next century will likely seriously hinder bamboo, almost the sole source of food for endangered pandas. Only if bamboo can move to new habitats at higher elevations will pandas stand a chance, the researchers said.
However, if conservation programs wait too long, human inhabitants and activities could claim all of the new habitats capable of supporting bamboo in a warming world.
“It is tough, but I think there’s still hope, if we take action now,” said research team member Jianguo Liu, a sustainability scientist at Michigan State University. “If we wait, then we could be too late.”
The researchers used various climate-change models to project the future for three bamboo species relied on by pandas in the Qinling Mountain region of China, which represents about a quarter of the total remaining panda habitat. These models varied in their specific predictions, but each forecasted some level of temperature rise within the coming century.
The results suggest that if the bamboo is restricted to its current distribution area, between 80 and 100 percent of it will disappear by the end of the 21st century, because it won’t be able to grow under the increased temperatures.

Good Night, Exoplanet: Baby Name Book to Raise Science Funds

When new planets are discovered beyond the solar system, they often get boring designations such as HD 85512b or Gliese 667Cc. A startup hoping to liven up these names has launched a project to create a Baby Planet Name Book full of more colorful suggestions.
The planet name project is the first official product from Uwingu, a new company that aims to raise money for space research, exploration and education.
Now, for 99 cents apiece, you can nominate any name you like to join the new planet name registry, and you can also vote for your favorites among the current list.
“The many, many planets discovered across the galaxy in past 20 years are a tribute to our natural human desire to explore beyond the horizon,” planet-hunting astronomer Geoff Marcy of the University of California at Berkeley said in a statement. “Now people all over the world can participate in these discoveries in a new way, giving identities and even personality to billions of planets in our galaxy for the first time.”
To be clear, Uwingu officials say the names won’t be official, and won’t be attached to particular planets — yet. The only body authorized to officially name celestial objects is the International Astronomical Union (IAU), which hasn’t so far expressed an interest in changing the status quo of planet naming.
But Uwingu hopes astronomers might use the names from the project to refer to the new planets they keep finding, at least informally. The current tally of confirmed planets is almost 800 and growing, so that’s a lot of worlds that need good names.

Why We Haven’t Met Any Aliens

The story goes like this: Sometime in the 1940s, Enrico Fermi was talking about the possibility of extraterrestrial intelligence with some other physicists. They were impressed that life had evolved quickly and progressively on Earth. They figured our galaxy holds about 100 billion stars, and that an intelligent, exponentially-reproducing species could colonize the galaxy in just a few million years. They reasoned that extraterrestrial intelligence should be common by now. Fermi listened patiently, then asked, simply, “So, where is everybody?” That is, if extraterrestrial intelligence is common, why haven’t we met any bright aliens yet? This conundrum became known as Fermi’s Paradox.

Since then, the Paradox has become ever more baffling. Paleontology has shown that organic life evolved quickly after the Earth’s surface cooled and became life-hospitable. Given simple life forms, evolution shows progressive trends toward larger bodies, brains, and social complexity. Evolutionary psychology has revealed several credible paths from simpler social minds to human-level creative intelligence. So evolving intelligence seems likely, given a propitious habitat—and astronomers think such habitats are common. Moreover, at least 150 extrasolar planets have been identified in the last few years, suggesting that life-hospitable planets orbit most stars. Yet 40 years of intensive searching for extraterrestrial intelligence have yielded nothing: no radio signals, no credible spacecraft sightings, no close encounters of any kind.

It looks, then, as if we can answer Fermi in two ways. Perhaps our current science over-estimates the likelihood of extraterrestrial intelligence evolving. Or, perhaps evolved technical intelligence has some deep tendency to be self-limiting, even self-exterminating. After Hiroshima, some suggested that any aliens bright enough to make colonizing space ships would be bright enough to make thermonuclear bombs, and would use them on each other sooner or later. Maybe extraterrestrial intelligence always blows itself up. Indeed, Fermi’s Paradox became, for a while, a cautionary tale about Cold War geopolitics.

I suggest a different, even darker solution to the Paradox. Basically, I think the aliens don’t blow themselves up; they just get addicted to computer games. They forget to send radio signals or colonize space because they’re too busy with runaway consumerism and virtual-reality narcissism. They don’t need Sentinels to enslave them in a Matrix; they do it to themselves, just as we are doing today. Once they turn inwards to chase their shiny pennies of pleasure, they lose the cosmic plot. They become like a self-stimulating rat, pressing a bar to deliver electricity to its brain’s ventral tegmental area, which stimulates its nucleus accumbens to release dopamine, which feels…ever so good.

The fundamental problem is that an evolved mind must pay attention to indirect cues of biological fitness, rather than tracking fitness itself. This was a key insight of evolutionary psychology in the early 1990s; although evolution favors brains that tend to maximize fitness (as measured by numbers of great-grandkids), no brain has capacity enough to do so under every possible circumstance. Evolution simply could never have anticipated the novel environments, such as modern society, that our social primate would come to inhabit. That would be a computationally intractable problem, even for the new IBM Blue Gene/L supercomputer that runs 280 trillion operations per second. Even long-term weather prediction is easy when compared to fitness prediction. As a result, brains must evolve short-cuts: fitness-promoting tricks, cons, recipes and heuristics that work, on average, under ancestrally normal conditions.

The result is that we don’t seek reproductive success directly; we seek tasty foods that have tended to promote survival, and luscious mates who have tended to produce bright, healthy babies. The modern result? Fast food and pornography. Technology is fairly good at controlling external reality to promote real biological fitness, but it’s even better at delivering fake fitness—subjective cues of survival and reproduction without the real-world effects. Having real friends is so much more effort than watching Friends. Actually colonizing the galaxy would be so much harder than pretending to have done it when filming Star Wars or Serenity. The business of humanity has become entertainment, and entertainment is the business of feeding fake fitness cues to our brains.

Fitness-faking technology tends to evolve much faster than our psychological resistance to it. With the invention of the printing press, people read more and have fewer kids. (Only a few curmudgeons lament this.) With the invention of Xbox 360, people would rather play a high-resolution virtual ape in Peter Jackson’s King Kong than be a perfect-resolution real human. Teens today must find their way through a carnival of addictively fitness-faking entertainment products: iPods, DVDs, TiVo, Sirius Satellite Radio, Motorola cellphones, the Spice channel, EverQuest, instant messaging, MDMA, BC bud. The traditional staples of physical, mental and social development—athletics, homework, dating—are neglected. The few young people with the self-control to pursue the meritocratic path often get distracted at the last minute. Take, for example, the MIT graduates who apply to do computer game design for Electronics Arts, rather than rocket science for NASA.

Around 1900, most inventions concerned physical reality: cars, airplanes, Zeppelins, electric lights, vacuum cleaners, air conditioners, bras, zippers. In 2005, most inventions concern virtual entertainment—the top 10 patent-recipients were IBM, Canon, Hewlett-Packard, Matsushita, Samsung, Micron Technology, Intel, Hitachi, Toshiba and Fujitsu—not Boeing, Toyota or Victoria’s Secret. We have already shifted from a reality economy to a virtual economy, from physics to psychology as the value-driver and resource-allocator. We are already disappearing up our own brainstems. Our neurons over-stimulate each other, promiscuously, as our sperm and eggs decay, unused. Freud’s pleasure principle triumphs over the reality principle. Today we narrow-cast human-interest stories to each other, rather than broadcasting messages of universal peace and progress to other star systems.

Maybe the bright aliens did the same. I suspect that a certain period of fitness-faking narcissism is inevitable after any intelligent life evolves. This is the Great Temptation for any technological species—to shape their subjective reality to provide the cues of survival and reproductive success without the substance. Most bright alien species probably go extinct gradually, allocating more time and resources to their pleasures, and less to their children. They eventually die out when the game behind all games—the Game of Life—says “Game Over; you are out of lives and you forgot to reproduce.”

Heritable variation in personality might allow some lineages to resist the Great Temptation and last longer. Some individuals and families may start with an “irrational” Luddite abhorrence of entertainment technology, and they may evolve ever more self-control, conscientiousness and pragmatism. They will evolve a horror of virtual entertainment, psychoactive drugs and contraception. They will stress the values of hard work, delayed gratifica tion, child-rearing and environmental stewardship. They will combine the family values of the religious right with the sustainability values of the Greenpeace left. Their concerns about the Game of Life will baffle the political pollsters who only understand the rhetoric of status and power, individual and society, rights and duties, good and evil, us and them.

This, too, may be happening already. Christian and Muslim fundamentalists and anti-consumerism activists already understand exactly what the Great Temptation is, and how to avoid it. They insulate themselves from our creative-class dreamworlds and our EverQuest economics. They wait patiently for our fitness-faking narcissism to go extinct. Those practical-minded breeders will inherit the Earth as like-minded aliens may have inherited a few other planets. When they finally achieve contact, it will not be a meeting of novel-readers and game-players. It will be a meeting of dead-serious super-parents who congratulate each other on surviving not just the Bomb, but the Xbox.

Livin’ on ur plants, harvestin ur sunshine
The ability to gather sunlight and convert it to useable energy has been the plant kingdom’s longstanding trump card (along with some bacteria and fungi) when it comes to “greatest evolutionary adaptation known”. Unlike the rest of the tree of life ,photosynthetic organisms have billions of years worth of free energy to count on. It’s an all-you-can-eat buffet of solar food. The evolution of the animal world actually wouldn’t have happened if photosynthetic organisms hadn’t started pumping oxygen into our atmosphere in the early years of Earth.
For the first time, scientists have found evidence that an insect shares this ability. Some pea aphids, like the one pictured above, can produce plant-like orange pigments called carotenoids. In addition to chlorophyll, these are the same compounds that leaves use to harvest light, and also why we get those beautiful browns and oranges in autumn.
The aphid seems to have “stolen” the genes from a fungus, and then through some non-photosynthetic mechanism, is using the pigments to create ATP, life’s energy currency.
This isn’t the first time a larger organism has developed the ability to harvest sunlight! A sea slug was discovered a few years ago that borrowed photosynthetic genes from microscopic algae. Looks like the branches on that tree of life cross over more than we thought.

Brinicle: The Icy Finger of Death

Imagine being a seastar off the coast of Antarctica. Sure life is cold, but you crawl around feeling out for food and keeping an eye - or rather five eye spots, those light sensitive organs on the tip of each of your arms - on the ground. And despite your slow and steady motion you are a ruthless predator: a carnivore with a voracious appetite for bivalves, urchins and yes you’ll even take on the occasional crab if it crosses your path.

Indeed, on the Southern Ocean seafloor you are still king of the creepy crawlies; the top predator in a sea where cold waters allow for slow motion assault. But there is one thing that can take you down and it also moves not with lightning fast speed, but in a slow freezing trickle. And similar to your own attack method of extending your stomach out of your body and enveloping your prey in digestive enzymes, this killer enshrines everything it touches in an icy tomb.

Beware the brinicle.

This amazing phenomena was captured for the first time on film during the shooting of Discovery’s Frozen Planet series, which airs Sunday, March 18 at 8 p.m. ET

Watch it.

It could save your life.

How to Watch the Mars Close-Up This Weekend
February’s spectacular planetary show continues. After Venus and  Jupiter lined  up in the night sky last week, the distance between Earth and Mars  is now shrinking to its smallest in more than two years.
On March 3 Mars will be in opposition to the sun, providing excellent  opportunities for viewing the Red Planet.
The celestial event known as Mars  opposition occurs whenever Earth passes between the sun and the Red  Planet, approximately once every two years and two months. This makes  Mars visible opposite the sun in the Earth’s sky, which is a great time  to view the Red planet because the sun’s rays illuminate the full face  of Mars. Because the two planets’ orbits regularly bring them close  together, it also provides a good time to launch Mars missions such as  the recent Mars  Science Laboratory.
Mars and Earth will actually be at their closest on March 5, so you  have a decent chance to catch the Red Planet anytime in the next few  weeks.
How to Watch
To spot Mars with your naked eye, look for a bright orange-red dot  in the eastern sky shortly after the sun sets. The planet, which can be  distinguished from stars because it doesn’t twinkle, will rise to its highest  position in the southern sky around midnight.
Those with a modest-sized telescope should have good views of Mars’  surface features, including its white polar caps.
Anyone without access to a telescope can catch a live feed of the  opposition event from the Slooh Space Camera on March 3 starting at 8:00 p.m.  PST. Come back tomorrow evening to our site for an embedded video from  Slooh. The Slooh show will feature commentary by the organization’s  Patrick Paolucci, Astronomy Magazine columnist Bob Berman, and  some special guests.

On March 3 Mars will be in opposition to the sun, providing excellent opportunities for viewing the Red Planet.

The celestial event known as Mars opposition occurs whenever Earth passes between the sun and the Red Planet, approximately once every two years and two months. This makes Mars visible opposite the sun in the Earth’s sky, which is a great time to view the Red planet because the sun’s rays illuminate the full face of Mars. Because the two planets’ orbits regularly bring them close together, it also provides a good time to launch Mars missions such as the recent Mars Science Laboratory.

Mars and Earth will actually be at their closest on March 5, so you have a decent chance to catch the Red Planet anytime in the next few weeks.

How to Watch

  • To spot Mars with your naked eye, look for a bright orange-red dot in the eastern sky shortly after the sun sets. The planet, which can be distinguished from stars because it doesn’t twinkle, will rise to its highest position in the southern sky around midnight.
  • Those with a modest-sized telescope should have good views of Mars’ surface features, including its white polar caps.
  • Anyone without access to a telescope can catch a live feed of the opposition event from the Slooh Space Camera on March 3 starting at 8:00 p.m. PST. Come back tomorrow evening to our site for an embedded video from Slooh. The Slooh show will feature commentary by the organization’s Patrick Paolucci, Astronomy Magazine columnist Bob Berman, and some special guests.
