Reading This Will Change Your Brain
From Newsweek:
A leading neuroscientist says processing digital information can rewire your circuits. But is it evolution?
Is technology changing our brains? A new study by UCLA neuroscientist Gary Small adds to a growing body of research that says it is. And according to Small's new book, "iBRAIN: Surviving the Technological Alteration of the Modern Mind," a dramatic shift in how we gather information and communicate with one another has touched off an era of rapid evolution that may ultimately change the human brain as we know it. "Perhaps not since early man first discovered how to use a tool has the human brain been affected so quickly and so dramatically," he writes. "As the brain evolves and shifts its focus towards new technological skills, it drifts away from fundamental social skills."

How You Can Tell A Person's Class: The Wealthy Fidget, Yawn And Generally Appear Rude, Say Researchers
Photo: Body language: Those from wealthier backgrounds tend to appear more distracted than their less well off counterparts
From The Daily Mail:
Fidgeting, yawning and doodling have long been equated with boredom.
But if the person you're speaking to isn't paying attention, they may be rich rather than rude, a study has revealed.
It found that posh people fidget more - making it possible to tell a person's social class by their body language.
Researchers said those born into privilege may feel less of a need to make a good impression and so are more inclined to fidget when talking to other people.
In contrast, their poorer counterparts are anxious to make a good impression and so are more attentive.

From International Herald Tribune:
Forensic evidence that has helped convict thousands of defendants for nearly a century is often the product of shoddy scientific practices that should be upgraded and standardized, according to accounts of a draft report by the nation's pre-eminent scientific research group.
The report by the National Academy of Sciences is to be released this month. People who have seen it say it is a sweeping critique of many forensic methods that the police and prosecutors rely on, including fingerprinting, firearms identification and analysis of bite marks, blood spatter, hair and handwriting.

Britannica 2.0 Shows Wikipedia How It's Done
From Times Online:
The 240-year-old Encyclopaedia Britannica has taken a giant leap into the world of Web 2.0 with the launch of a new online version where users can contribute and edit content.
In a move that takes it head to head with Wikipedia, new features on the Britannica site will allow users to edit and contribute articles in return for the glory of having their name attached to the submission.
However, “voyeuristic” Wikipedia fans ought not to get too excited by the changes as all submissions will undergo a strict vetting process and may or may not make the cut, according to Britannica 's president, Jorge Cauz.
“We’re not trying to be a wiki - that’s the last thing we want to be,” Mr Cauz told The Times.

East Asia Builds World's Largest Radio Telescope Network
From China View:
SHANGHAI, Feb.1 (Xinhua) -- East Asian astronomers are building the world's largest radio telescope array to see the deep into the galaxy and black holes and more accurately determine the orbits of lunar probes such as China's Chang'e-1.
The array, called the East Asia Very Long Baseline Interferometry (VLBI) consortium, consists of 19 radio telescopes from China, Japan and the Republic of Korea (ROK) that cover an area with a diameter of 6,000 kilometers from northern Japan's Hokkaido to western China's Kunming and Urumqi.
The VLBI technology is widely used in radio astronomy. It combines the observations simultaneously made by several telescopes to expand the diameter and increase magnification.

From ABC News:
Google Inc. and two nonprofit partners Wednesday launched a Web site that lets consumers test their Internet connections to reveal possible interference and traffic management by service providers.
The site, Measurement Lab, addresses a need among academics who want to gather data on how Internet connections work in practice. While the workings of the core Internet "highways" are well known and standardized, it's difficult to find out what happens on the network of an Internet service provider, between the "highway" and the customer's home.

US Wind Power Grew By 50% In 2008 As China's Doubled
Vail Resorts said Tuesday that it would buy credits for wind power like that generated by the turbines at the Gray County Wind Farm in Kansas. Orlin Wagner/Associated Press (New York Times)
From Ars Technica:
The Global Wind Energy Council, an industry group, has totaled the past year's growth in generating capacity, and found that wind had a very good year, with US wind power having its highest annual growth ever, and China doubling its installed capacity.
Many renewable energy technologies, most notably photovoltaic, are struggling to reach what's called "grid parity," where the cost of the power they generate matches that of fossil fuel generation. One technology that's largely there is wind, as maturing turbine technology and economies of scale have made the economics of wind power quite competitive. Those economics can clearly be seen in the latest figures on the growth of the wind industry, which cover 2008. Among the milestones: wind was the largest component of Europe's growth in electric generating capacity, the US became the world's top wind energy producer, and China doubled its installed capacity in just a year—for the fourth year running.

From Science Daily:
ScienceDaily (Feb. 4, 2009) — Cardiff University researchers, who are part of a British-German team searching the depths of space to study gravitational waves, may have stumbled on one of the most important discoveries in physics, according to an American physicist.
Craig Hogan, a physicist at Fermilab Centre for Particle Astrophysics in Illinois is convinced that he has found proof in the data of the gravitational wave detector GEO600 of a holographic Universe – and that his ideas could explain mysterious noise in the detector data that has not been explained so far.

Oldest Fossil Evidence for Animals Found

From Live Science:
The oldest fossilized evidence of animals has been unearthed in Oman and reveals that tiny sea sponges were abundant 635 million years ago, long before most of the planet's other major animal groups evolved, according to a new analysis.
This early life hardly looked like us, but some of the so-called demosponges can be sizable today. Demosponges still make up 90 percent of all sponges on Earth and 100 percent of Earth's largest sponges, including barrel sponges, which can be larger than an old-style phone booth.
The ancient demosponges — probably measuring across no more than the width of a fork tine — were pinned down via fossilized steroids, called steranes, which are characteristic of the cell membranes of the sponges, rather than via direct fossils of the sponges themselves.

The Father Factor: How Dad's Age Increases Baby's Risk of Mental Illness
When a large study linked schizophrenia to paternal age, some researchers wondered if the root cause, rather than age, was that men who had waited had the makings of the disease themselves. Getty Images
From Scientific American:
Could becoming a father after age 40 raise the risks that your children will have a mental illness?
* It is widely recognized that a 40-year-old woman has an increased risk of bearing a child with Down syndrome. What is not known is that a 40-year-old man has the same risk of fathering a child with schizophrenia—and even higher odds of his offspring having autism. The risk of bipolar disorder appears to rise as well.
* In the past couple of decades, the number of older fathers has increased. Birth rates for men older than 40 have jumped as much as 40 percent since 1980.
* The mechanisms behind the higher risks are still being investigated, although scientists have several hypotheses that could someday lead to better therapies or possibly even cures for these mental illnesses.
When my wife, Elizabeth, was pregnant, she had a routine ultrasound exam, and I was astonished by the images. The baby’s ears, his tiny lips, the lenses of his eyes and even the feathery, fluttering valves in his heart were as crisp and clear as the muscles and tendons in a Leonardo da Vinci drawing. Months before he was born, we were already squabbling about whom he looked like. Mostly, though, we were relieved; everything seemed to be fine.

Intelligent Life Could Be Thriving On 40,000 Planets
This planet, located near the centre of the Milky Way about 20,000 light years from us, is just one of the 40,000 which could be harbouring intelligent life
From Daily Mail:
Science’s quest to discover life on Mars has so far failed to find even one little green man.
But not to worry. Aliens could be alive and well on almost 40,000 other planets.
Researchers have calculated that up to 37,964 worlds in our galaxy are hospitable enough to be home to creatures at least as intelligent as ourselves.
Astrophysicist Duncan Forgan created a computer programme that collated all the data on the 330 or so planets known to man and worked out what proportion would have conditions suitable for life.
The estimate, which took into account factors such as temperature and availability of water and minerals, was then extrapolated across the Milky Way.
Three scenarios of how life could develop were also taken into account.

From National Geographic:
Tucked into Monday's media splash for the launch of oceans in Google Earth was another, quieter announcement: A module for exploring Mars is now part of the popular 3-D mapping tool.
Users can soar through alien trenches, see through the eyes of robotic visitors, and toggle between natural color, "night vision," and rainbow-hued topographic views of the red planet.
Virtual Mars is based on pictures from the many orbiters and landers—past and present—that have been sent to study Martian landscapes.
Much of the imagery used in Google Mars 3-D is already publicly available and easy to access on sites across the Internet, noted project leader Noel Gorelick.

Five Years of Facebook: A Retrospective
From PC World:
It doesn't seem like five years since Facebook appeared on the scene. I was slow to join the throng--my friends list numbers only 242 of the 110 million people who have joined the site since its inception.
Facebook is less juvenile in look-and-feel than MySpace, which it has overtaken in popularity. It is also a lot cleaner, again in look-and-feel but also in content. It also lacks the sexual content that plagues MySpace.
Facebook is more generalist in approach than some other social networking sites, such as Linked-In, which seem aimed at people looking for jobs and customers instead of communicating with people they already know. If you want to exploit your friends, Linked-In seems an excellent place to do it. And they'll exploit you in return.

New, Free Software Enables You To Keep Tabs On Others' Whereabouts, And Vice Versa, Using Cell Phones, Says Natali Del Conte
(CBS) Google is releasing free software Wednesday that enables people to keep track of each other using their cell phones.
CNET got a sneak peek at it, and CNET-TV Senior Editor and Early Show contributor Natali Del Conte explained how it works on the show Tuesday.
She says "Latitude" uses GPS systems and what's called cell tower triangulation to do the job. The software seeks the closest three cell towers and, with GPS, combines the data to show where someone is.
It is designed to work on any phone with Internet capabilities, except the iPhone.
"Latitude" is being marketed as a tool that could help parents keep tabs on their children's locations, but it can be used for anyone to find anyone else, assuming permission is given.

From Science Daily:
ScienceDaily (Feb. 4, 2009) — A variation in the gene FOXO3A has a positive effect on the life expectancy of humans, and is found much more often in people living to 100 and beyond – moreover, this appears to be true worldwide.
A research group in the Faculty of Medicine at the Christian-Albrechts-University in Kiel (CAU) has now confirmed this assumption by comparing DNA samples taken from 388 German centenarians with those from 731 younger people. The results of the study appear this week in the journal Proceedings of the National Academy of Sciences ("PNAS").

Timing of Seasons Is Changing
Image from Businessweek
From Live Science:
The Earth's seasons have shifted back in the calendar year, with the hottest and coldest days of the years now occurring almost two days earlier, a new study finds.
This shift could be the work of global warming, the researchers say.
To figure this out, scientists at the University of California, Berkeley and Harvard studied temperature data from 1850 to 2007 compiled by the University of East Anglia's Climate Research Unit in the United Kingdom.
They found that temperatures over land in the 100-year period between 1850 and 1950 showed a simple, natural pattern of variability, with the hottest day of the year in the Northern Hemisphere landing around July 21. But from the mid-1950s onward (the period when global average temperatures began to rise), the hottest day came 1.7 days earlier.

From Yahoo News/Space.com:
NASA has delayed the planned Feb. 12 launch of the space shuttle Discovery by least a week to allow extra time to evaluate vital fuel valves on the spacecraft, agency officials said late Tuesday.
Discovery was slated to launch toward the International Space Station on Feb. 12 to deliver the last set of U.S.-built solar arrays to the orbiting laboratory. The mission is now scheduled to blast off no earlier than Feb. 19 at about 4:41 a.m. EST (0941 GMT), but an official launch target will be determined at a later date.
"By looking at it right now, we think it's about a week delay, but we're not going to put pressure on the team," said John Shannon, NASA's space shuttle program manager, in a briefing at the agency's Kennedy Space Center in Florida. "We'll just let the information drive us."

Astronomers Discover Link Between Supermassive Black Holes And Galaxy Formation
Two giant elliptical galaxies, NGC 4621 and NGC 4472, look similar from a distance, as seen on the right in images from the Sloan Digital Sky Survey. But zooming into these galaxies' cores with Hubble Space Telescope reveals their differences (left, black and white images). NGC 4621 shows a bright core, while NGC 4472 is much dimmer. The core of this galaxy is populated with fewer stars. Many stars have been slung out of the core when the galaxy collided and merged with another. Their two supermassive black holes orbited each other, and their great gravity sent stars careening out of the galaxy's core. (Credit: NASA/AURA/STScI and WikiSky/SDSS)
From Science Daily:
ScienceDaily (Feb. 3, 2009) — A pair of astronomers from Texas and Germany have used a telescope at The University of Texas at Austin's McDonald Observatory together with Hubble Space Telescope and many other telescopes around the world to uncover new evidence that the largest, most massive galaxies in the universe and the supermassive black holes at their hearts grew together over time.
"They evolved in lockstep," said The University of Texas at Austin's John Kormendy, who co-authored the research with Ralf Bender of Germany's Max-Planck-Institute for Extraterrestrial Physics and Ludwig Maximilians University Observatory. The results are puiblished in this week's issue of Astrophysical Journal Letters.

From Scientific American:
LONDON (Reuters) - The United States overtook Germany as the biggest producer of wind power last year, new figures showed, and will likely take the lead in solar power this year, analysts said on Monday.
Even before an expected "Obama bounce" from a new President who has vowed to boost clean energy, U.S. wind power capacity surged 50 percent last year to 25 gigwatts (GW) -- enough to power more than five million homes.
Political and business leaders worldwide have urged "green growth" spending on clean energy to fight both recession and climate change.
German wind power capacity reached nearly 24 GW, placing it second ahead of Spain and fourth-placed China, which doubled its installed wind power for the forth year running, said the Brussels-based Global Wind Energy Council.

Biofuels More Harmful To Humans Than Petrol And Diesel, Warn Scientists
From The Guardian:
Corn-based bioethanol has higher burden on environment and human health, says US study
Some biofuels cause more health problems than petrol and diesel, according to scientists who have calculated the health costs associated with different types of fuel.
The study shows that corn-based bioethanol, which is produced extensively in the US, has a higher combined environmental and health burden than conventional fuels. However, there are high hopes for the next generation of biofuels, which can be made from organic waste or plants grown on marginal land that is not used to grow foods. They have less than half the combined health and environmental costs of standard gasoline and a third of current biofuels.

Smallest Exoplanet Is Most Earth-like Yet
From Wired News:
The smallest exoplanet ever seen is less than twice the size of Earth, and orbits a star similar to our sun. Astronomers recently spotted this world, the most Earth-like planet yet discovered, with the COROT satellite.
"For the first time, we have unambiguously detected a planet that is 'rocky' in the same sense as our own Earth,” said Malcolm Fridlund, ESA COROT project scientist.
For all its similarity to our own globe, though, it is still a far cry away from a habitable Earth-twin. For one thing, it is so hot — between 1,830 and 2,730 degrees Fahrenheit — that scientists think it might be covered in lava. It orbits extremely close to its sun and whips around the star once every 20 hours.

When Dreams Come True
Photo from Haikudesigns
From Science News:
People interpret dreams in ways that affect their waking lives, especially when those dreams support pre-existing beliefs
Dreams don’t just bubble up at night and then evaporate like morning dew once the sun rises. What you dream shapes what you think about your upcoming plans and your closest confidants, especially if nighttime reveries fit with what’s already convenient to believe, a new report finds.
In an effort to understand whether people take their dreams seriously, Carey Morewedge of Carnegie Mellon University in Pittsburgh and Michael Norton of Harvard University surveyed 149 college students attending universities in India, South Korea or the United States about theories of dream function.
People across cultures often assume that dreams contain hidden truths, much as Sigmund Freud posited more than a century ago, Morewedge and Norton report in the February Journal of Personality and Social Psychology. In fact, many individuals consider dreams to provide more meaningful information regarding daily affairs than comparable waking thoughts do, the two psychologists conclude.

From CBS News:
Larry Magid Says Windows 7 Is What Vista Should Have Been
(CBS) I don't know why it took so long, but Microsoft has finally fixed Vista. Only it isn't calling it Vista. Instead the company is working on what it's calling a new version of Windows -- Windows 7. The operating system isn't commercially available but is likely to be out by the end of the year.
I don't know how much Microsoft plans to charge for the upgrade once it's officially available, but they should give it away free to anyone who bought Vista or a PC with Vista preinstalled. Even though there are some new features, Windows 7 strikes me mostly as a bug fix. It speeds up Windows and fixes one of its most annoying "features" and makes one particularly useful change to the user interface. It seems to me that anyone who paid for Vista is entitled to this upgrade.

From The New York Times:
Sea explorers probing the depths of the English Channel have discovered what they say is a legendary British warship that sank in a fierce storm in 1744, losing more than 900 men and possibly four tons of gold coins that could be worth $1 billion.
The team found the wreckage of the warship, the H.M.S. Victory, last year and confirmed its identity through a close examination of 41 bronze cannons visible on the sandy bottom, Gregory P. Stemm, head of the discovery team, said Monday at a news conference in London.
The team lifted two of the cannons from the seabed and gave them to the British Defense Ministry, he said. The team’s leaders are now negotiating with British authorities on the disposition of the artifacts and treasure before the divers attempt further recoveries.

Nuclear Fusion Fission Hybrid Reactor To Destroy Waste
Photo from ABC News (Australia)
From Future Pundit:
The idea behind long term (tens or hundreds of thousands of years) nuclear waste storage facilities is that we can't solve the nuclear waste disposal problem quickly. But matter is so manipulable in the hands of sufficiently smart scientists and technologists that sometimes supposedly insolvable problems become solvable. UT Austin researchers think they know how to convert nuclear power plant waste into far safer elements with a hybrid reactor.
AUSTIN, Texas--Physicists at The University of Texas at Austin have designed a new system that, when fully developed, would use fusion to eliminate most of the transuranic waste produced by nuclear power plants.

From Science Daily:
ScienceDaily (Feb. 2, 2009) — Over 14,000 years ago during the last Pleistocene Ice Age, when a large part of the European continent was covered in ice and snow, Neanderthals in the region of Gibraltar in the south of the Iberian peninsula were able to survive because of the refugium of plant and animal biodiversity. Today, plant fossil remains discovered in Gorham's Cave confirm this unique diversity and wealth of resources available in this area of the planet.
The international team jointly led by Spanish researchers has reconstructed the landscape near Gorham's Cave in Gibraltar, by means of paleobotanical data (plant fossil records) located in the geological deposits investigated between 1997 and 2004. The study, which is published in the Quaternary Science Reviews, also re-examines previous findings relating to the glacial refugia for trees during the ice age in the Iberian Peninsula.

Japan Warns Of Volcano Eruption Within 48 Hours
From The Telegraph:
Tens of thousands of people living near Japan's volatile Mount Asama have been told to brace themselves for a major volcanic eruption within 48 hours.
The volcano is one of Japan's most active and last erupted in September 2004 when molten rock and ash blanketed areas more than 125 miles from the crater.
Even by Japanese standards, Mount Asama is an active volcano, with frequent bouts of activity over recent years. The most famous eruption came in 1783 and caused the deaths of more than 1,500 people and widespread damage.
Japan's Meteorological Agency yesterday raised the alert level for the 8,420ft peak, warning of an imminent eruption and forbidding anyone to scale the mountain.
More than 45,000 nearby residents have been put on alert and told to be ready to leave their homes within two hours notice.

Rubik's Revenge: Cube Inventor Set To Launch 21st Century Version Of Iconic Puzzle
From The Daily Telegraph:
For a few years the Rubik's Cube had millions under its spell.
Umpteen hours were spent on the infuriating device, which became the fastest selling puzzle of all time.
Eventually of course, more and more discovered the secret of how to solve it and word spread that youngsters were cracking the Cube in as little as eight seconds.
To the inventor, Professor Erno Rubik, this was merely the challenge to create something even more difficult.
And he appears to have done just that with the Rubik's 360, which is due to be formally unveiled this week.
Using the same formula of an apparently simple task that is maddeningly hard to complete, it involves moving plastic balls through a set of transparent spheres.
Professor Rubik, 64, a reclusive Hungarian, said: 'The 360 is one of the most innovative and exciting puzzles we've developed since the Cube, adopting elements of myoriginal design, challenging the solver to use skill, dexterity and logic.'

Can A Person Be Scared To Death?
From Scientific American:
A 79-year-old woman dies in North Carolina after a heart attack brought on by terror.
A Charlotte, N.C., man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. In an attempt to elude cops after a botched bank robbery, the Associated Press reports that 20-year-old Larry Whitfield broke into and hid out in the home of Mary Parnell. Police say he didn't touch Parnell but that she died after suffering a heart attack that was triggered by terror. Can the fugitive be held responsible for the woman's death? Prosecutors said that he can under the state's so-called felony murder rule, which allows someone to be charged with murder if he or she causes another person's death while committing or fleeing from a felony crime such as robbery—even if it's unintentional.
But, medically speaking, can someone actually be frightened to death? We asked Martin A. Samuels, chairman of the neurology department at Brigham and Women's Hospital in Boston.

From The Telegraph:
An extinct animal has been brought back to life for the first time after being cloned from frozen tissue.
The Pyrenean ibex, a form of wild mountain goat, was officially declared extinct in 2000 when the last-known animal of its kind was found dead in northern Spain.
Shortly before its death, scientists preserved skin samples of the goat, a subspecies of the Spanish ibex that live in mountain ranges across the country, in liquid nitrogen.
Using DNA taken from these skin samples, the scientists were able to replace the genetic material in eggs from domestic goats, to clone a female Pyrenean ibex, or bucardo as they are known. It is the first time an extinct animal has been cloned.

My Comment: This is incredible. The implications of this development are profound. Extinct species will be able to be cloned and returned to life.

Too Much TV Linked To Future Fast-food Intake
From Science Daily:
ScienceDaily (Feb. 1, 2009) — High-school kids who watch too much TV are likely to have bad eating habits five years in the future. A new study followed almost 2000 high- and middle-school children and found that TV viewing times predict a poor diet in the future.
Dr Daheia Barr-Anderson worked with a team of researchers from the University of Minnesota to investigate the relationship between television and diet. She said, "To our knowledge, this is the first study to examine the association between television viewing and diet over the transition from adolescence into young adulthood. We've shown that TV viewing during adolescence predicts poorer dietary intake patterns five years later".

From Watts Up With That:
It is generally accepted that CO2 is lagging temperature in Antarctic graphs. To dig further into this subject therefore might seem a waste of time. But the reality is, that these graphs are still widely used as an argument for the global warming hypothesis. But can the CO2-hypothesis be supported in any way using the data of Antarctic ice cores?
At first glance, the CO2 lagging temperature would mean that it’s the temperature that controls CO2 and not vice versa.

With its sea turtles and surf shops, the Big Island of Hawaii resembles a tropical, watery world. Yet for climate scientists, it's the ideal place to study low-humidity air and the processes that dehydrate the atmosphere.
From the sprawling dome of Mauna Loa — 11,000 feet above Hawaii's coconut-fringed beaches — climate scientists David Noone and Joe Galewsky can track water vapor that's traveled as far as the equator and the pole. They're the first to try to measure vapor's chemical signature in real-time in order to understand the processes controlling the global water cycle.

The Tech That Makes The Super Bowl Super
From CNET:
At its core, football represents the polar opposite of technology: A bunch of large men run around a field, battling for position and the control of a small pigskin ball.
Of course, the production of an actual NFL game requires lots of technology--from the headsets coaches use to communicate, to the computers used to calculate statistics to the HD cameras that record the contest for the viewing audience.
When it comes to the Super Bowl, one of the biggest sporting events in the world, technology has always played a very central role, and this year is no exception.

Science May Explain Our Love Of Sports
From Kansas City:
A relatively recent discovery in science may explain our country’s obsession with watching sports — like the expected audience of 90 million or so for today’s Super Bowl.
They call them “mirror neurons,” and they fire in your brain much the same way whether you’re doing something or watching someone else do it. The discovery killed a lot of assumptions scientists had about brain activity.
It explains why you get hungry if you see someone eating a juicy steak, thirsty when you see a cold drink — or excited when you watch sports.
“In a way, your brain is behaving the same way as (the athletes you’re watching),” says Marco Iacoboni, a neuroscientist at UCLA and the author of Mirroring People: The New Science of How We Connect with Others. “Your brain is making the same signals as the athletes you see on the screen, even if you’re just on the sofa eating popcorn.”

Scientists To Football Players: Give Us Your Brains
From Popular Science:
Amidst a growing body of evidence tying severe health problems to multiple concussions, researchers are tapping NFL stars for a more hands-on corroboration
Whenever rich people gather, charities flock hoping to solicit donations of time and money. But Chris Nowinski is asking NFL players at the Super Bowl this weekend for something a bit more personal. He wants them to donate their brains to science. And he’s getting what he wants.
Nowinski is the founder of the Sports Legacy Institute (SLI), which along with the Boston University School of Medicine is conducting autopsies on former athletes to research the effect of concussive impacts. To date eight former NFL players have promised to donate their brains to science after their death. Nowinski is a former professional wrestler who understands firsthand the potential ramifications of head impacts.

Do Huge NFL Players Help Teams Win?
From Live Science:
When the Arizona Cardinals meet the Pittsburgh Steelers in Sunday's Super Bowl, every starting offensive lineman will be a member of the 300-pound club.
This season, there were more than 600 players — about 20 percent of the league — in triple donuts. Even with 6-foot plus heights, their Body Mass Index (BMI) levels are all in the range of grade 2 obesity, one step below what's called morbid obesity.
This super-sizing of NFL players has accelerated in recent years, and some studies suggest health risks are growing. But studies are conflicting on this point.
And the big question on the minds of coaches and owners: Do heavier players mean more wins? No, one study found.

The Physics of ‘The Hit’ -- Superbowl Science
Baltimore running back Willis McGahee was seriously injured after a collision with the Steelers' Ryan Clark in the A.F.C. championship game. Julie Jacobson/Associated Press
From The New York Times:
TAMPA, Fla. — Isaac Newton’s apple hurt considerably less than Ryan Clark’s coconut. But they did have a few things in common.
Clark’s shockingly violent hit on the Baltimore Ravens’ Willis McGahee two Sundays ago — a full-speed, helmet-to-helmet crash that left McGahee unconscious and Clark all but — didn’t just follow the N.F.L.’s rules, but Newton’s as well. Force equaled mass times acceleration. Momentum was conserved. And the bodies finally came to rest, McGahee’s on a stretcher.
“How I look at it, you can be the hammer or the nail,” the inner scientist in Clark explained this week. “I try to be the hammer.”
The tackle, the art of making the ball carrier not stay in motion, is football’s most primeval action. Amusing physicists the way batting averages do actuaries, collisions lead the highlight reels, impart the force of a deadly car crash, and rely upon kinematics that date to a considerably different big bang.

at Castelvetrano, in Sicily, Italy. Image from Wikipedia
From Live Science:
To honor their gods and goddesses, ancient Greeks often poured blood or wine on the ground as offerings. Now a new study suggests that the soil itself might have had a prominent role in Greek worship, strongly influencing which deities were venerated where.
In a survey of eighty-four Greek temples of the Classical period (480 to 338 B.C.), Gregory J. Retallack of the University of Oregon in Eugene studied the local geology, topography, soil, and vegetation — as well as historical accounts by the likes of Herodotus, Homer, and Plato — in an attempt to answer a seemingly simple question: why are the temples where they are?
No clear pattern emerged until he turned to the gods and goddesses. It was then that he discovered a robust link between the soil on which a temple stood and the deity worshiped there.

From New Scientist:
AN UPDATED family tree of the animal kingdom could radically change the way we think about the evolution of species.
According to conventional thinking, simple animals, including sponges, jellyfish and corals, evolved step-by-step in a linear fashion into those with more complex bodies, such as mammals.
Now Rob DeSalle of the American Museum of Natural History in New York and his colleagues have challenged this way of thinking.
The team analysed DNA and other molecular evidence across the animal kingdom, including tiny sea creatures called placozoans. They have found that the placozoans are the closest living thing to the ancestor of all animals.

Is Google Broken? -- News Updates On Google's Glitch Today
Google’s Internet search service malfunctioned for nearly 55 minutes Saturday morning, upending users around the world with search results that carried false safety warnings and Web links that did not work.
The company acknowledged Saturday that all searches produced links with the same warning message: “This site may harm your computer.” Clicking on any of the links led to an error message stating that the desired site could not be reached.
“What happened?” Google explained in its blog. “Very simply, human error.”
Google said it periodically updates its list of sites suspected of carrying dangerous software that could harm computers, and that Saturday morning a Google employee mistyped a Web address for one such site, causing all sites to be flagged harmful.
There was some momentary tension when Google seemed to imply that the glitch was caused by StopBadware.org, the company that helps Google determine which sites are unsafe. Google later posted a statement that took the blame for the error.

Action Sunrise At The Very Large Array
From Live Science:
Astronomers recently used the NSF's Very Large Array (VLA) radio telescope (above) to help find the most distant water yet seen in the Universe, in a galaxy more than 11 billion light-years from Earth. Previously, the most distant water had been seen in a galaxy less than 7 billion light-years from Earth.
The soggy galaxy is dubbed MG J0414+0534. In a region near its core, water molecules are acting as masers, the radio equivalent of lasers, to amplify radio waves at a specific frequency.
The water molecules showed themselves with a tell-tale radio "fingerprint." The first indication came from the giant, 100-meter-diameter radio telescope in Effelsberg, Germany, and scientists confirmed the discovery using the VLA. The astronomers say their finding indicates that such giant, water masers were more common in the early Universe than they are today. MG J0414+0534 is seen as it was when the Universe was roughly one-sixth of its current age.

Inside Alaska's Explosive Redoubt Volcano

From Live Science:
Mount Redoubt volcano in Alaska could erupt within days to weeks, say scientists at the U.S. Geological Survey, amazing the rest of us with their certainty.
Here's what makes them so sure: Magma rising toward the surface from beneath a volcano like Redoubt can cause earthquakes and other seismic rumblings. And seismic activity at Redoubt, which is 106 miles (170 km) southwest of Anchorage, has increased recently.
"If you're going to bring magma to the surface you've got to break rock, and every time rocks break at the subsurface beneath a volcano, that's an earthquake," said volcanologist Charles Mandeville of the American Museum of Natural History in New York. "They're recording a whole bunch of earthquakes almost continuously right now," he said, referring to scientists at the Alaska Volcano Observatory in Anchorage.

The Biology Of Dating: Why Him, Why Her?
From Time Magazine:
Ah, the eternal question: why is HE with HER? Biological anthropologist Helen Fisher thinks she has found the answer after studying the academic literature on personality and after poring over 40,000 responses to a questionnaire on an online dating site. A Rutgers professor and paid advisor for Chemistry.com, Fisher not only believes in romantic chemistry, but is zeroing in on specific chemicals. She spoke with TIME about her latest book, Why Him, Why Her: Finding Real Love by Understanding Your Personality Type.
A lot of things influence who we're attracted to, but one thing that has always puzzled scientists is the role that personality plays in mate selection. Have you solved that riddle?
There are two parts of personality. There's character, which is everything you grew up to believe and do and think. And then there's temperament, which is your inherited traits. Some people are more stubborn than others, some are more curious, some are more aggressive. What I'm trying to do is add the role of biology, of temperament, to our human understanding of love.

How Does A Dog Walk? Surprisingly, Many Of Us Don't Really Know
How do dogs walk? It turns out that all four-legged animals step with their left hind leg followed by their left foreleg. Then they step with their right hind leg followed by the right foreleg, and so on. Animals differ from one another only in the timing of that stepping. (Credit: iStockphoto/Tim McCaig)
From Science Daily:
ScienceDaily (Jan. 29, 2009) — Despite the fact that most of us see our four-legged friends walking around every day, most of us-including many experts in natural history museums and illustrators for veterinary anatomy text books-apparently still don't know how they do it.
A new study published in the January 27th issue of Current Biology, a Cell Press publication, shows that anatomists, taxidermists, and toy designers get the walking gait of horses and other quadruped animals wrong about half the time. That's despite the fact that their correct walking behavior was described and published more than 120 years ago.
