'Fiscal cliff' deal 'in sight': Obama












President Barack Obama says it appears that an agreement to avoid the fiscal cliff is “in sight,” but says it's not yet complete and work continues.


Obama says this has been a “pressing issue on people's minds,” and tells an audience of middle-class taxpayers the deal would, among other things, extend unemployment benefits for Americans “who are still out there looking for a job.”











He voiced regret that the work of the administration and lawmakers on Capitol Hill won't produce a “grand bargain” on tax-and-spend issues, but said that “with this Congress, it couldn't happen at that time.”


Officials familiar with the negotiations say an agreement would raise tax rates on family income over $450,000 a year and increase the estate tax rate.


Any overall deal was also likely to include a provision to prevent a spike in milk prices with the new year, extend unemployment benefits due to expire and protect doctors who treat Medicare patients from a 27 percent cut in fees.


Both the House and Senate were on track to meet on the final day of the year, although there was no expectation that a compromise could be approved by both houses by midnight, even if one were agreed to.


Instead, the hope of the White House and lawmakers was to seal an agreement, enact it and send it to Obama for his signature before taxpayers felt the impact of higher income taxes or federal agencies began issuing furloughs or taking other steps required by spending cuts.


Regardless of the fate of the negotiations, it appeared all workers would experience a cut in their-home pay with the expiration of a two-year cut in payroll taxes.


Officials who described the negotiations did so on condition of anonymity, citing the confidential nature of the discussions.


A spokesman for McConnell, Don Stewart, said the Kentucky lawmaker and Biden "continued their discussion late into the evening and will continue to work toward a solution." Underscoring the flurry of activity, another GOP aide said the two men had conversations at 12:45 a.m. and 6:30 a.m. Monday.


Unless an agreement is reached and approved by Congress by the start of New Year's Day, more than $500 billion in 2013 tax increases will begin to take effect and $109 billion will be carved from defense and domestic programs


Though the tax hikes and budget cuts would be felt gradually, economists warn that if allowed to fully take hold, their combined impact — the so-called fiscal cliff — would rekindle a recession.


"This whole thing is a national embarrassment," Sen. Bob Corker, R-Tenn., said Monday on MSNBC, adding that any solution Congress would swallow at this late stage would be inconsequential. "We still haven't moved any closer to solving our nation's problems."


In a move that was sure to irritate Republicans, Reid was planning — absent a deal — to force a Senate vote Monday on Obama's campaign-season proposal to continue expiring tax cuts for all but those with income exceeding $200,000 for individuals and $250,000 for couples.


In one sign of movement on Sunday, Republicans dropped a demand to slow the growth of Social Security and other benefits by changing how those payments are increased each year to allow for inflation.


Obama had offered to include that change, despite opposition by many Democrats, as part of earlier, failed bargaining with House Speaker John Boehner, R-Ohio, over a larger deficit reduction agreement. But Democrats said they would never include the new inflation formula in the smaller deal now being sought to forestall wide-ranging tax boosts and budget cuts, and Republicans relented.


"It's just acknowledging the reality," Sen. Susan Collins, R-Maine, said of the GOP decision to drop the idea.


There was still no final agreement on the income level above which decade-old income tax cuts would be allowed to expire. While Obama has long insisted on letting the top 35 percent tax rate rise to 39.6 percent on earnings over $250,000, he'd agreed to boost that level to $400,000 in his talks with Boehner. GOP senators said they wanted the figure hoisted to at least that level.


Senators said disagreements remained over taxing large inherited estates. Republicans want the tax left at its current 35 percent, with the first $5.1 million excluded, while Democrats want the rate increased to 45 percent with a smaller exclusion.


The two sides were also apart on how to keep the alternative minimum tax from raising the tax bills of nearly 30 million middle-income families and how to extend tax breaks for research by business and other activities.

iPad App Video Review: Anomaly Korea






The tower offense pioneers over at 11 Bit Studios finally released the sequel to their smash hit, Anomaly Warzone Earth. They branched out a bit, releasing the amusing Funky Smugglers and the dreamlike puzzler, Sleepwalker’s Journey, but now they’re back, and as this game will remind you a few times, Baghdad was just the beginning. The battle against a mysterious alien tower menace continues with new visuals, units, modes, and an awesome but sometimes hilarious Korean undertone.


The core game here is still the same, with you planning convoy routes through enemy infested streets, able to change your route on the fly. You technically continue to play as the invisible but ever-present commando unit, with your various power-ups, such as smoke screen, repair field, and others, activating and placing them with a simple tap or two. New units like the Horangi tank join your ranks, with unique unit abilities, like the aforementioned tank’s area of effect blast. As you make your way through the world, you’ll collect resources and upgrade units as well.






It’s not just new unit and enemy types mixing things up. For example, there are now artillery zones that will automatically be targeted and be fired upon as you pass through them, but only after a short countdown. Subtle additions like this are quite elegant, adding more dimensions of strategy without changing anything from previous games. Another great new addition is the Art of War trials. As you play and do well, you’ll unlock these brief but brutal challenges, and they are very satisfying to complete.


The visuals have received an upgrade, as has the voice acting. Still, there’s something kind of funny about all the Korean accented English speaking, along with the still excellent Asian-styled soundtrack. It’s not bad at all, but can feel out of place at first. All in all, Anomaly Korea offers more of the same, but improved, building upon the last game in all the right ways. You don’t even need to have played the first game to enjoy this one, so go ahead and download it for the current price of three dollars. I can’t wait to see where in the world this anomaly pops up next.

Armstrong better, Green Day to resume tour in 2013






LOS ANGELES (AP) — Green Day is going back out on the road.


The Grammy-winning punk band announced new tour dates Monday.






The band canceled the rest of its 2012 club schedule and postponed the start of a 2013 arena tour after singer-guitarist Billie Joe Armstrong‘s substance abuse problems emerged publicly in September when he had a profane meltdown on the stage of the iHeartRadio Music Festival in Las Vegas.


Armstrong told fans in a statement Monday that he’s “getting better every day” and “the show must go on.”


The tour is scheduled to begin March 28 at the Allstate Arena in the Chicago area.


The band released its most recent album, “Tre,” on Dec. 11, more than a month ahead of schedule.

Personal Health: Food Myths

Let’s start the new year on scientifically sound footing by addressing some nutritional falsehoods that circulate widely in cyberspace, locker rooms, supermarkets and health food stores. As a result, millions of people are squandering hard-earned dollars on questionable, even hazardous foods and supplements.

For starters, when did “chemical” become a dirty word? That’s a question raised by one of Canada’s brightest scientific minds: Joe Schwarcz, director of the Office for Science and Society at McGill University in Montreal. Dr. Schwarcz, who has received high honors from Canadian and American scientific societies, is the author of several best-selling books that attempt to set the record straight on a host of issues that commonly concern health-conscious people.

I’ve read two of his books, “Science, Sense and Nonsense” (published in 2009) and “The Right Chemistry” (2012), and recently attended a symposium on the science of food that Dr. Schwarcz organized at McGill.

What follows are tips from his books and the symposium that can help you make wiser choices about what does, and does not, pass your lips in 2013.

CURED MEATS Many health-conscious people avoid cured meats like hot dogs and bacon because the nitrites with which they are preserved can react with naturally occurring amines to form nitrosamines. Nitrosamines have produced mutations in cells cultured in the laboratory and cancer in animals treated with very high doses.

As an alternative, sandwich lovers often buy organic versions of processed meats or products without added nitrites. Without preservatives, these foods may not be protected from bacterial contamination. And despite their labels, they may contain nitrites. According to Dr. Schwarcz, organic processed meats labeled “uncured” may be preserved with highly concentrated, nitrate-rich celery juice treated with a bacterial culture that produces nitrites.

If you’re really concerned about your health, you’d be wise to steer clear of processed meats — organic, nitrite-free or otherwise. High saturated fat and salt content place them low on the nutritional totem pole.

MEAT GLUE Never heard of it? You may have eaten it, especially if you dine out often. At WD-50 in New York, the chef, Wylie Dufresne, makes his famous shrimp noodles with the enzyme transglutaminase, a k a meat glue. It binds protein molecules, gluing together small pieces of fish, meat or poultry.

The Japanese use meat glue to create artificial crab meat from pollock. Others use it to combine lamb and scallops, or to make sausages that hold together without casings.

Sound frightening? It shouldn’t. The enzyme is classified by the Food and Drug Administration as “generally recognized as safe,” and there is no reason to think otherwise. Our bodies produce it to help blood clot, Dr. Schwarcz points out. When consumed, it breaks down like any protein into its component amino acids in our digestive tracts.

There is, however, one possible indirect hazard: If glued-together animal protein is not thoroughly cooked, dangerous bacteria that originally contaminated the meat could remain viable within the fused product.

TRANS FATS The removal of heart-damaging trans fats from processed foods is a much-ballyhooed boon to health. But “not all trans fats are fiends,” Dr. Schwarcz notes. Certain ones can legally, and healthfully, be added to dairy products, meal-replacement bars, soy milk and fruit juice.

The word “trans” refers to the arrangement of hydrogen and carbon atoms in a fatty acid. The trans formation linked to heart disease is formed when vegetable oils are hardened to prolong shelf life in a manufacturing process called hydrogenation. Natural trans fats, like those in meat and dairy products, take a slightly different form, resulting in an entirely different effect on health.

The most widely consumed “good” trans fat is conjugated linoleic acid, which research has shown can help weight-conscious people lose fat and gain muscle. Various studies have suggested that C.L.A., now widely sold as a supplement, also can enhance immune function and reduce atherosclerosis, high blood pressure and inflammation.

ORGANIC OR NOT? Wherever I shop for food these days, I find an ever-widening array of food products labeled “organic” and “natural.” But are consumers getting the health benefits they pay a premium for?

Until the 20th century, Dr. Schwarcz wrote, all farming was “organic,” with manure and compost used as fertilizer and “natural” compounds of arsenic, mercury and lead used as pesticides.

Might manure used today on organic farms contain disease-causing micro-organisms? Might organic produce unprotected by insecticides harbor cancer-causing molds? It’s a possibility, Dr. Schwarcz said. But consumers aren’t looking beyond the organic sales pitch.

Also questionable is whether organic foods, which are certainly kinder to the environment, are more nutritious. Though some may contain slightly higher levels of essential micronutrients, like vitamin C, the difference between them and conventionally grown crops may depend more on where they are produced than how.

A further concern: Organic producers disavow genetic modification, which can be used to improve a crop’s nutritional content, enhance resistance to pests and diminish its need for water. A genetically modified tomato developed at the University of Exeter, for example, contains nearly 80 times the antioxidants of conventional tomatoes. Healthier, yes — but it can’t be called organic.

FARMED SALMON Most of the salmon consumed nowadays is farmed. Even if we all could afford the wild variety, there’s simply not enough of it to satisfy the current demand for this heart-healthy fish.

There may be legitimate concerns about possible pollutants in farmed salmon, but one concern that is a nonissue involves that “salmon” color, produced by adding astaxanthin to fish feed. This commercially made pigment is an antioxidant found naturally in algae, and it is carried up the food chain to give wild salmon its color, too.

NUTS Growing up, I was often warned to avoid nuts because they’re “fattening.” Now I know better. Research has shown that people who regularly eat nuts and nut butters in normal amounts weigh less, on average, than nut avoiders.

The fat in nuts is unsaturated and heart-healthy. Nuts are also good sources of protein, antioxidants, vitamins, minerals and fiber, and can help keep between-meal hunger at bay. The same is true of avocados — just don’t go overboard.

Tribune Co. emerges from bankruptcy









The last day of 2012 is the first of a new era for Tribune Co.

After spending more than four years embroiled in a contentious Chapter 11 bankruptcy case, the reorganized Chicago-based media company emerged Monday under new owners and a newly appointed board, freed from its massive debt and facing an uncertain future.

Senior creditors Oaktree Capital Management, Angelo, Gordon & Co. and JPMorgan Chase & Co. are set to take control of Tribune Co.’s storied portfolio of publishing and broadcasting assets, including the Chicago Tribune, officials said.

It was an almost anticlimactic end to a long and painful chapter in Tribune Co.'s 165-year history. Late Sunday, the new Tribune Co. named its board of directors, filed notification with the Delaware bankruptcy court where the bulk of legal wrangling took place and declared its existence.

"It took a long time to get here," said Ken Liang, a managing director at Oaktree and a new member of the board. "It was a tough restructuring. We're pretty excited about the exit."

The new board also will include Tribune Co. CEO Eddy Hartenstein; Ross Levinsohn, who recently left as interim chief executive of Yahoo Inc.; Craig Jacobson, a well-known entertainment lawyer; Peter Murphy, a former strategy executive at Walt Disney Co. and Ceasars Entertainment; Bruce Karsh, Oaktree president; and Peter Liguori, a former top television executive at Fox and Discovery.

Liguori is expected to be named chief executive of Tribune Co. going forward.

Hartenstein, who is publisher of the Los Angeles Times, has been CEO of Tribune Co. since May 2011. He will remain in the role until the board convenes its first meeting in the next several weeks, where it will name the company’s executive officers, according to a company statement.

“Tribune will emerge from the bankruptcy process as a multi-media company with a great mix of profitable assets, strong brands in major markets and a much-improved capital structure,” Hartenstein said in the statement.

Tribune Co. owns 23 television stations, including WGN-Ch. 9, WGN America, eight daily newspapers and other media assets, all of which the reorganization plan valued at $4.5 billion after cash distributions and new financing. Eventually, all the assets are expected to be sold, according to the new owners.

They take the reins of a company that saw its worth essentially cut in half since 2007, when Chicago billionaire Sam Zell took it private in an $8.2 billion leveraged buyout. The rapid decline was mostly due to falling newspaper valuations in the face of digital competition. The anticipated hiring of Liguori suggests that broadcasting will be the operational focus going forward, according to several media analysts.

Los Angeles-based Oaktree, the largest shareholder, with about 23 percent of the equity, appointed two of seven board members. Both Angelo Gordon and JPMorgan have roughly a 9 percent stake and appointed one seat each. The three jointly appointed two more board members, with the final seat occupied by the chief executive.

Among the outgoing board members is Zell, whose deal was seen at the time as an alternative to the squabbles within Tribune Co. that threatened to break apart the then-publicly traded company. But the Great Recession and plummeting advertising revenues across all media, especially the struggling newspaper industry, made the company’s resulting $13 billion debt load untenable.

Tribune Co. filed for Chapter 11 bankruptcy protection in December 2008. Zell blamed a “perfect storm” of industry and economic forces. But the bankruptcy case turned on charges leveled by junior creditors that saddling the company with such a debt burden left it insolvent from the outset.

Led by an aggressive distressed debt fund called Aurelius Capital Management, the junior creditors pressed litigation that stretched out the case for three and a half years in a Delaware court before U.S. Bankruptcy Judge Kevin Carey confirmed the reorganization plan in July. An emergency appeal to stay that decision was dismissed by the 3rd U.S. Circuit Court of Appeals in September. In November, the Federal Communications Commission signed off on waivers needed to transfer Tribune Co.’s broadcast properties to the new ownership, clearing the last hurdle to its emergence from Chapter 11.

“Usually, bankruptcy cases like this take much less time and cost less money,” said Douglas Baird, a bankruptcy expert and law professor at the University of Chicago.

Baird said legal fees for most large corporate bankruptcies run 3 to 4 percent of the company’s total worth. The Tribune Co. case, which will likely cost the company more than $500 million in legal and other professional fees, was more than twice that percentage, due to both the extended litigation and the company’s declining valuation.

Before cash distributions and new financing, a 2012 analysis by financial adviser Lazard valued the broadcasting assets, including the TV stations, WGN-AM 720, CLTV and national cable channel WGN America, at $2.85 billion. Other strategic assets, such as online job site CareerBuilder and cable channel Food Network, are worth $2.26 billion.

Tribune Co.’s newspaper holdings, including the Tribune, Los Angeles Times and six other daily publications, have withered to $623 million in total value, according to Lazard. In 2006, entertainment mogul David Geffen made a $2 billion cash offer for the Los Angeles Times.

3rd quarter: Bears 20, Lions 17









Coach Lovie Smith and the Chicago Bears were in need of a win and a prayer Sunday to make the NFC playoffs. The Bears had to beat the Lions and have the Packers beat the Vikings to reach the playoffs and possibly extend Smith's nine-year run in Chicago.


Detroit fought back and cut the Bears' once-commanding lead to 20-17 with a 10-yard TD pass from Matthew Stafford to Will Heller at the 6:35 mark of the third quarter.


The Lions cut the Bears' lead to 20-10 just before halftime, as Stafford hit Kris Durham on a 25-yard TD pass with 12 seconds to play before intermission.





Olindo Mare's second field goal, this one from 40 yards out, extended the Bears' lead to 20-3 with 1:49 to play.


Tim Jennings made his league-high ninth interception with 2:38 left in the half to put the Bears' offense back in business inside Lions territory.


Matt Forte's 1-yard touchdown run -- after a pass-interference call against Detroit drawn by Brandon Marshall -- gave the Bears a 17-3 lead with 3:26 to go in the first half.


The Bears' defense delivered again to set up the score. Israel Idonije knocked the ball from quarterback Matthew Stafford's hand and Julius Peppers recovered on the Lions' 10-yard line.


Mare's 33-yard field goal gave the Bears a 10-3 lead with 2:59 left in the first quarter. Joe Anderson forced a fumble on the kickoff after the Bears' first score and Eric Weems recovered, setting up Mare's kick.


Mare blew a chance to extend the lead, missing a 43-yard attempt wide right with just under five minutes remaining in the half.


The Bears grabbed a 7-3 lead when Earl Bennett caught a screen pass from Jay Cutler and took it 60 yards for a touchdown with 4:33 left in the first quarter.


The Lions struck first, with Jason Hanson connecting on a 44-yard field goal for a 3-0 Detroit lead with 5:54 to go in the quarter. The kick came after replay overturned a fumble that had been ruled on Stafford and recovered by the Bears.


The Bears' offense started well, with Cutler hitting receiver Alshon Jeffery for a 55-yard gain on their first play. But the drive sputtered and the Bears were forced to punt.


The Bears also could earn a playoff spot with a tie and a Vikings loss in Minneapolis. A Bears win and a Vikings loss or tie also would do the trick.
 
The Bears have been to the playoffs three times under Smith, with the last playoff appearance coming in 2010.

General manager Phil Emery had praise for Smith while speaking before the game on WBBM-AM (780).

"Great team-first person," Emery said of Smith. "He's done an outstanding job coaching the Bears."

As to whether Smith must reach the playoffs to retain his job, Emery said, "When you're evaluating players, you're always looking for body of work. No different when you're evaluating coaches.

"It's is the full season, and the whole body of work. ... It's about steady progress toward our goals, which is to win championships.''

As for needing help from Green Bay to reach the playoffs, Emery said, "We're rooting against Minnesota. ... We're not rooting for Green Bay."

Hidden Powers of Your Mouse






You use your mouse for just about everything: you drag, you drop, you highlight, you scroll. But even if you click your mouse a thousand times a day, I bet I’ve got a few secret mouse tricks you’ve never heard of.


Click Tricks
You surely know that double clicking highlights a word, and you might even know that triple clicking highlights a paragraph. But have you ever wanted to select a column of text in a Word document, without getting all the text to the left and right of it? Here’s how you can: Hold down the alt and left mouse button (on a Mac, option-left mouse), and drag the cursor over the section you want to select. The coolest thing about this trick is that the text you are selecting does not even need to be formatted as a column for this to work.3e0bc  uyl ep83 large1 Hidden Powers of Your Mouse






[Related: 8 Microsoft Word Shortcuts You Probably Don't Know]


Scroll Tricks
Most mice have a scroll wheel. Sure, it takes you up and down on a page, but in combination with other keys, it can do much more:


  • Scroll sideways: In many versions of Excel, holding down the shift key while scrolling will take you sideways. That’s super helpful in a big spreadsheet.

  • Scroll wheel as back button: In most web browsers, if you hold the shift key while using the scroll wheel, it works like the back button: You can fly through all the sites you’ve recently visited. (Some mice have side buttons that work like back and forward buttons in your browser, too.)

  • Scroll to zoom: Holding ctrl and scrolling lets you zoom in or out of the page you’re viewing. Ctrl-scroll up zooms you in; ctrl-scroll down zooms you back out. On a Mac, this trick will zoom in and out your whole screen, not just the document you’re in.

Windows-Specific Tricks
While most of the tricks I’ve listed so far work in either Windows or Mac OS, here are a few that are specific to Windows machines:


  • To maximize a window: drag the title bar to the top.

  • To minimize all windows except the active window: “Shake” the title bar. Then if you want to restore all the windows you just minimized with this shortcut, just click again on the title bar of the window in view.

  • To view two windows in a 50-50 split: Drag the title bar of one document to the left edge of your screen, then drag a second document to the right edge; they will snap into position in a nifty side-by-side view.

Bonus Sneaky Trick
Suppose you want to walk away from your hyper-secure work computer for a few minutes and not have to re-log in when you get back. Sure, you could change the sleep settings, but this idea is much more clever: Set your mouse on top of your analog watch or a clock. The mouse tracks the second hand’s movement and it tricks your computer into thinking you’re still busy working. Of course, there are valid security reasons for NOT using this trick, but I still think it’s cool that it works.

Well: Exercise and the Ever-Smarter Human Brain

Anyone whose resolve to exercise in 2013 is a bit shaky might want to consider an emerging scientific view of human evolution. It suggests that we are clever today in part because a million years ago, we could outrun and outwalk most other mammals over long distances. Our brains were shaped and sharpened by movement, the idea goes, and we continue to require regular physical activity in order for our brains to function optimally.

Phys Ed

Gretchen Reynolds on the science of fitness.

The role of physical endurance in shaping humankind has intrigued anthropologists and gripped the popular imagination for some time. In 2004, the evolutionary biologists Daniel E. Lieberman of Harvard and Dennis M. Bramble of the University of Utah published a seminal article in the journal Nature titled “Endurance Running and the Evolution of Homo,” in which they posited that our bipedal ancestors survived by becoming endurance athletes, able to bring down swifter prey through sheer doggedness, jogging and plodding along behind them until the animals dropped.

Endurance produced meals, which provided energy for mating, which meant that adept early joggers passed along their genes. In this way, natural selection drove early humans to become even more athletic, Dr. Lieberman and other scientists have written, their bodies developing longer legs, shorter toes, less hair and complicated inner-ear mechanisms to maintain balance and stability during upright ambulation. Movement shaped the human body.

But simultaneously, in a development that until recently many scientists viewed as unrelated, humans were becoming smarter. Their brains were increasing rapidly in size.

Today, humans have a brain that is about three times larger than would be expected, anthropologists say, given our species’ body size in comparison with that of other mammals.

To explain those outsized brains, evolutionary scientists have pointed to such occurrences as meat eating and, perhaps most determinatively, our early ancestors’ need for social interaction. Early humans had to plan and execute hunts as a group, which required complicated thinking patterns and, it’s been thought, rewarded the social and brainy with evolutionary success. According to that hypothesis, the evolution of the brain was driven by the need to think.

But now some scientists are suggesting that physical activity also played a critical role in making our brains larger.

To reach that conclusion, anthropologists began by looking at existing data about brain size and endurance capacity in a variety of mammals, including dogs, guinea pigs, foxes, mice, wolves, rats, civet cats, antelope, mongooses, goats, sheep and elands. They found a notable pattern. Species like dogs and rats that had a high innate endurance capacity, which presumably had evolved over millenniums, also had large brain volumes relative to their body size.

The researchers also looked at recent experiments in which mice and rats were systematically bred to be marathon runners. Lab animals that willingly put in the most miles on running wheels were interbred, resulting in the creation of a line of lab animals that excelled at running.

Interestingly, after multiple generations, these animals began to develop innately high levels of substances that promote tissue growth and health, including a protein called brain-derived neurotrophic factor, or BDNF. These substances are important for endurance performance. They also are known to drive brain growth.

What all of this means, says David A. Raichlen, an anthropologist at the University of Arizona and an author of a new article about the evolution of human brains appearing in the January issue of Proceedings of the Royal Society Biology, is that physical activity may have helped to make early humans smarter.

“We think that what happened” in our early hunter-gatherer ancestors, he says, is that the more athletic and active survived and, as with the lab mice, passed along physiological characteristics that improved their endurance, including elevated levels of BDNF. Eventually, these early athletes had enough BDNF coursing through their bodies that some could migrate from the muscles to the brain, where it nudged the growth of brain tissue.

Those particular early humans then applied their growing ability to think and reason toward better tracking prey, becoming the best-fed and most successful from an evolutionary standpoint. Being in motion made them smarter, and being smarter now allowed them to move more efficiently.

And out of all of this came, eventually, an ability to understand higher math and invent iPads. But that was some time later.

The broad point of this new notion is that if physical activity helped to mold the structure of our brains, then it most likely remains essential to brain health today, says John D. Polk, an associate professor of anthropology at the University of Illinois at Urbana-Champaign, and co-author, with Dr. Raichlen, of the new article.

And there is scientific support for that idea. Recent studies have shown, he says, that “regular exercise, even walking,” leads to more robust mental abilities, “beginning in childhood and continuing into old age.”

Of course, the hypothesis that jogging after prey helped to drive human brain evolution is just a hypothesis, Dr. Raichlen says, and almost unprovable.

But it is compelling, says Harvard’s Dr. Lieberman, who has worked with the authors of the new article. “I fundamentally agree that there is a deep evolutionary basis for the relationship between a healthy body and a healthy mind,” he says, a relationship that makes the term “jogging your memory” more literal than most of us might have expected and provides a powerful incentive to be active in 2013.

Airlines' plans for 2013 up in the air









Airfares will be on the rise in 2013, and those niggling airline fees will metamorphose into optional bundles of services.


Meanwhile, onboard amenities, such as Internet access, entertainment options and refreshed interiors, will abound among U.S. carriers, but tight seating in coach probably won't improve.


And 2013 might be the year you'll finally be able to keep your smartphone, iPad or Kindle turned on during takeoffs and landings.





Those are some of the predictions airline industry experts foresee in the new year. Here's the lowdown on fares, fees and flight experience for 2013.


Higher fares forecast


Airlines pushed through six fare increases in 2012. Expect a similar number in the new year, said Rick Seaney, co-founder of FareCompare.com.


"I wouldn't be surprised to see airfares rise like they did this year, between 3 and 6 percent domestically," Seaney said. That's because airlines will succeed in properly balancing supply and demand by trimming the number of seats they offer to match "decent, but bordering on tepid, demand."


Fares are typically driven by four main factors: competition, most of all, then supply, demand and oil prices. "If you look at those drivers, they are, for the most part, on the airlines' side, which gives them pricing power," Seaney said.


That doesn't mean there won't be good airfare deals on some flights on some routes. And consumers will still see lower prices during off-peak days, such as Tuesday, Wednesday and Saturday departures and off-peak seasons, such as late January and early February. Like this year, summertime fares probably will stay relatively high, he said.


Airline mergers can also affect fares, and a huge one could take place early in 2013. American Airlines and US Airways are in talks about combining.


The general consensus among consumer advocates is that airline mergers aren't good for passengers.


"Any time you have two big airlines merging, that means consumers have less choice and competition is reduced, which only translates to higher prices," said Charlie Leocha, director of the Consumer Travel Alliance.


However, a bit of new evidence bucks that conventional wisdom. Despite four mega-mergers in the U.S. airline industry during the past seven years, fares have not increased significantly, just 1.8 percent per year, according to a December report from professional services firm PwC. In fact, average domestic fares decreased 1 percent from 2004 to 2011 when inflation is factored in, the report found.


Fliers know full well, however, that the fare isn't all that counts nowadays. There are those fees.


Fees get a makeover


The most noticeable trend in recent years with airline fees is that there are more of them: fees for checked bags, aisle seats, onboard meals, among many others. 


"What we hear is that people pay their fare and get to the airport and feel they're constantly being nickeled-and-dimed to death for things that used to be included," said Kate Hanni, founder of FlyersRights.org. 


The top five U.S. carriers alone generated more than $12 billion in fees in 2011, with even more expected through 2012, according to the PwC report.


What consumers call fees, airlines call "unbundling" — making a la carte choices from services that used to be included in the fare.


A likely trend for 2013 might be called "rebundling," airlines packaging a few now-optional services and charging for a tier of service.
