Bad news for red meat lovers: A new long-term study published online this week from the Harvard School of Public Health suggests that eating any type of red meat significantly ups one’s risk of premature death.
In retrospect I cannot but marvel at the extent of my naivety and ignorance then. But such was the mindset of almost everyone in my country in those fateful two weeks, after Tokyo Electric Power Company's Fukushima Daiichi nuclear plant was plunged into “station blackout” by the impact of the tsunami of March 11 last year.
回首過去，我無法不對自己當時表現出的幼稚和無知程度感到驚訝。但在受去年3•11海嘯影響，東京電力公司(Tokyo Electric Power Company)下屬福島第一核電站陷入“全廠斷電”狀態之後的兩周中——這兩週對我們的命運產生了重大影響——在我的國家，幾乎每一個人都是這種心態。
What I simply did not recognise was that Japan was on the edge of an existential crisis, as a cascading nuclear accident rapidly unfolded. For 48 hours from March 14, disaster seemed especially imminent. Officials in the prime minister's office were gloomy if not desperate. Late on March 14 Masataka Shimizu, then president of Tepco, began telephoning officials and insinuating the company's intentions to abandon the plant and evacuate workers – compelling the then prime minister, Naoto Kan, to intervene decisively: he stormed into Tepco headquarters and ordered senior managers not to abandon ship. He also implored that a “death squad” be formed to continue the battle and inject water into the reactor vessels.
我當時完全沒有意識到，隨著一場重大核事故一環接一環地迅速展開，日本正處於一場事關生死存亡的危機邊緣。 3月14日之後的48小時內，大難臨頭的感覺似乎尤其明顯。首相辦公室的官員們即便沒有絕望，也已十分悲觀了。 3月14日晚間，時任東電公司總裁的清水正孝(Masataka Shimizu)開始致電政府官員，暗示該公司欲捨棄核電廠並疏散工人——這迫使時任日本首相的菅直人(Naoto Kan)採取果斷干預：他氣沖沖地來到東電總部，命令高管們不得棄廠。他還要求組建“敢死隊”繼續戰鬥，並向反應堆容器注水。
The stakes, we now know, were extraordinarily high. Unbeknown to the public, Mr Kan also instructed Dr Shunsuke Kondo, chairman of the Japan Atomic Energy Commission (AEC), to draw up a “worst case scenario”. The resulting contingency document submitted on March 25 envisioned a hydrogen explosion in Unit 1 initiating a succession of meltdowns. The resulting plume of radiation could have led to the evacuation of Tokyo's metropolitan area, the report projected.
現在我們知道，當時的風險是何等之高。可我們並不知道，菅直人當時還指示日本原子能委員會(Atomic Energy Commission)委員長、近藤駿介(Shunsuke Kondo)博士設想出“可能出現的最糟糕情況”。這份3月25日提交的意外事故報告設想，1號機組將發生氫氣爆炸，繼而引發一連串的熔毀事故。該報告預計，由此產生的輻射將令東京的中心區域不得不進行疏散。
How could we have come to this? How could such a technologically advanced country be so unprepared? Reflecting on all this, after six months heading an independent commission on the accident, I have a better sense of what transpired – and the lessons Japan badly needs to learn from the disaster.
For one, our nuclear industry became ensnared in its twisted myth of “absolute safety”, propagated by interest groups seeking to gain broad acceptance for nuclear power. To wit, when Niigata Prefecture made plans in 2010 to conduct an accident drill for earthquake preparedness, the Nuclear and Industrial Safety Agency (NISA) recommended revising the plans to avoid sparking “unnecessary misunderstanding and anxiety” in the public; the prefecture was duly obliged to drop the earthquake premise in favour of a less menacing alternative – heavy snow! Similarly, utility companies' aversion to actions smacking of preparations for a potential nuclear disaster meant that development of robots to assist in nuclear accidents was never pursued.
At its core, Japan's nuclear safety regulatory regime was phoney. Regulators pretended to regulate; utilities pretended to be regulated. In reality, the latter were far more powerful in expertise and clout.
Beyond this hollow structure, an excessively risk-averse approach and a stovepipe structure within the administration did not serve the country well. Submitted to this critical test, inherent governance problems came to light, exposing two fundamental lessons. First, we need to overcome the myth of “absolute safety” and shatter the taboo that surrounds the very concept of risks in the nuclear energy business. We must also learn how to prepare for the unthinkable and unanticipated. This requires constant vigilance regarding the safety and security of nuclear plants as well as practices of nuclear waste disposal. Second, we need to build a regulatory body independent from the “nuclear village” of industry, bureaucrats, and academics working to promote nuclear energy. This demands a foundation of solid expertise and professionalism. And then, one more lesson – if we can call it a lesson – is that we really should look back upon the crisis with an appropriate sense of vulnerability and humility, recognising the uncontrollably destructive power of the nuclear monster once unleashed. This latter should never be forgotten.
Japanese society has learnt keenly the crucial role of leadership in a time of national crisis. It is precisely this issue that continues to divide and even polarise my country most profoundly. One year on people are still grasping for an answer as to what kind of leadership Japan really needs. In the course of our investigations, a staff member in Mr Kan's office made a striking statement – one he would never utter publicly out of respect to the evacuees: “How lucky we were that God is still with us in this country .”
The truth is that the imagined “worst-case scenario” was closer than anyone would wish to admit: but for the direction of the wind – towards the Pacific, not inland, in the four days after the earthquake; but for the manner in which the gate separating the reactor-well and the spent-fuel pool in Unit 4 broke – presumably facilitating the transfusion of water into the pool. Luck was undeniably on our side.
Is that it – providence? What of individuals? Some would say we had Mr Kan as the nation's “chief risk officer” at the critical moment, even if many would take offence at that. Masao Yoshida, manager of the plant at the time of the disaster, has also been praised for his courage and his leadership. His legendary kabuki play – making a show of agreeing to the order from Tepco's head office to halt water injections until further notification from the government, while simultaneously instructing his employees to proceed – has entered popular folklore.
Against the backdrop of ineptitude and risk-aversion at Tepco headquarters, admiration for him is understandable. Yet there is something troubling in a manager on the ground disobeying instructions from above so brazenly. It is even more troubling to see his rebellion widely praised in the court of public opinion. In truth, this a story without heroes – only a long sigh of relief and an invoice of vital morals to be parsed.

And contrary to what the researchers had hypothesized at the outset, processed meat isn’t the only culprit—unprocessed meat appears to increase the risk, as well.
The Los Angeles Times reports that eating a 3-ounce steak—roughly the size of a deck of cards—once per day upped the chances of dying during the study by 13 percent. Replace that serving with processed red meat, like a hot dog or two slices of bacon, and the risk shoots up to 20 percent among study participants.
While red meat has long been associated with increased risks of cancer, diabetes, and heart disease, CNN points out that the study, which tracked upward of 110,000 adults for more than 20 years, is the first to investigate how swapping it out altogether might increase a person’s lifespan.
The LAT with more numbers:
"Eating a serving of nuts instead of beef or pork was associated with a 19% lower risk of dying during the study. The team said choosing poultry or whole grains as a substitute was linked with a 14% reduction in mortality risk; low-fat dairy or legumes, 10%; and fish, 7%.”
The Times reports that at least one researcher, who wasn’t involved in the study, questioned the data since there could be many errors in the way food questionnaires were collected over the years. But the Harvard researchers stood by their conclusion that no amount of red meat is good for human health.
"If you want to eat red meat, eat the unprocessed products, and reduce it to two or three servings a week," the lead author of the study told the paper. "That would have a huge impact on public health."
Meanwhile, vegetarian diet advocate Dean Ornish, who wrote an editorial accompanying the study, said that a plant-based diet’s benefits weren’t limited to human health: Going meatless helps cut U.S. annual health care costs, minimize the livestock industry which contributes significantly to greenhouse gas emissions and slow the destruction of forests for pasture, he wrote.

An Enduring Measure of Fitness: The Simple Push-Up
As a symbol of health and wellness, nothing surpasses the simple push-up.
Practically everyone remembers the actor Jack Palance performing age-defying push-ups during his Oscar acceptance speech. More recently, Randy Pausch, the Carnegie Mellon professor whose last lecture became an Internet sensation, did push-ups to prove his fitness despite having pancreatic cancer.
“It takes strength to do them, and it takes endurance to do a lot of them,” said Jack LaLanne, 93, the fitness pioneer who astounded television viewers in the 1950s with his fingertip push-ups. “It’s a good indication of what kind of physical condition you’re in.”
The push-up is the ultimate barometer of fitness. It tests the whole body, engaging muscle groups in the arms, chest, abdomen, hips and legs. It requires the body to be taut like a plank with toes and palms on the floor. The act of lifting and lowering one’s entire weight is taxing even for the very fit.
“You are just using your own body and your body’s weight,” said Steven G. Estes, a physical education professor and dean of the college of professional studies at Missouri Western State University. “If you’re going to demonstrate any kind of physical strength and power, that’s the easiest, simplest, fastest way to do it.”
But many people simply can’t do push-ups. Health and fitness experts, including the American College of Sports Medicine, have urged more focus on upper-body fitness. The aerobics movement has emphasized cardiovascular fitness but has also shifted attention from strength training exercises.
Moreover, as the nation gains weight, arms are buckling under the extra load of our own bodies. And as budgets shrink, public schools often do not offer physical education classes — and the calisthenics that were once a childhood staple.
In a 2001 study, researchers at East Carolina University administered push-up tests to about 70 students ages 10 to 13. Almost half the boys and three-quarters of the girls didn’t pass.
Push-ups are important for older people, too. The ability to do them more than once and with proper form is an important indicator of the capacity to withstand the rigors of aging.
Researchers who study the biomechanics of aging, for instance, note that push-ups can provide the strength and muscle memory to reach out and break a fall. When people fall forward, they typically reach out to catch themselves, ending in a move that mimics the push-up. The hands hit the ground, the wrists and arms absorb much of the impact, and the elbows bend slightly to reduce the force.
In studies of falling, researchers have shown that the wrist alone is subjected to an impact force equal to about one body weight, says James Ashton-Miller, director of the biomechanics research laboratory at the University of Michigan.
“What so many people really need to do is develop enough strength so they can break a fall safely without hitting their head on the ground,” Dr. Ashton-Miller said. “If you can’t do a single push-up, it’s going to be difficult to resist that kind of loading on your wrists in a fall.”
And people who can’t do a push-up may not be able to help themselves up if they do fall.
“To get up, you’ve got to have upper-body strength,” said Peter M. McGinnis, professor of kinesiology at State University of New York College at Cortland who consults on pole-vaulting biomechanics for U.S.A. Track and Field, the national governing body for track.
Natural aging causes nerves to die off and muscles to weaken. People lose as much as 30 percent of their strength between 20 and 70. But regular exercise enlarges muscle fibers and can stave off the decline by increasing the strength of the muscle you have left.
Women are at a particular disadvantage because they start off with about 20 percent less muscle than men. Many women bend their knees to lower the amount of weight they must support. And while anybody can do a push-up, the exercise has typically been part of the male fitness culture. “It’s sort of a gender-specific symbol of vitality,” said R. Scott Kretchmar, a professor of exercise and sports science at Penn State. “I don’t see women saying: ‘I’m in good health. Watch me drop down and do some push-ups.’ ”
Based on national averages, a 40-year-old woman should be able to do 16 push-ups and a man the same age should be able to do 27. By the age of 60, those numbers drop to 17 for men and 6 for women. Those numbers are just slightly less than what is required of Army soldiers who are subjected to regular push-up tests.
If the floor-based push-up is too difficult, start by leaning against a countertop at a 45-degree angle and pressing up and down. Eventually move to stairs and then the floor.
Mr. LaLanne, who once set a world record by doing 1,000 push-ups in 23 minutes, still does push-ups as part of his daily workout. Now he balances his feet and each hand on three chairs.
“That way I can go way down, even lower than if I was on the floor,” he said. “That’s really tough.”

Three Mile Island offers treasure trove of lessons for Fukushima
By NAOYA KON / Staff Writer
THREE MILE ISLAND, Pennsylvania--When engineers inserted a camera probe into the stricken Unit 2 reactor of the Three Mile Island nuclear power plant here more than three decades ago, the images that appeared were quite unlike anything they had anticipated.
The reactor contained 177 nuclear fuel rods when the meltdown occurred in 1979. But the reactor core had hardly retained its original shape.
The camera captured images of fine, pimply and stone-like objects, according to Jack DeVine, 68, who worked for a technical division at General Public Utilities, the plant operator at the time.
Just as DeVine and other officials who were involved in post-disaster response at Three Mile Island discovered, there is no telling what the crippled reactors at the Fukushima plant will have in store.
The findings at Three Mile Island can provide plentiful lessons for the work that lies ahead at the disabled Fukushima No. 1 nuclear plant, located some 220 kilometers northeast of Tokyo.
In a recent interview, DeVine, who also helped set up an organization responsible for decontamination, said it is essential to start the work only after ascertaining the state of the reactor interiors and drawing up phased work programs leading to final decommissioning.
At Three Mile Island, unmanned robots equipped with cameras and endoscopes prowled around the interior of the reactor building as well as the reactor itself to provide a record of what had happened.
Although similar technologies are being deployed at the Fukushima facility, the conditions there, including radiation levels, are much more serious than those at the Three Mile Island plant. There is a strong possibility that new technology will have to be developed.
The Japanese government, along with Tokyo Electric Power Co., operator of the crippled Fukushima plant, jointly released a road map in December for decommissioning the plant. It defined three stages for the process of decommissioning, which is expected to take between 30 and 40 years.
In the case of Three Mile Island, it took 11 years from the time of the accident to finish the fuel removal.
The road map for Japan envisages that it will take more than double that time to achieve the same result. The fuel removal work itself is expected to take between 10 and 15 years.
At Three Mile Island, only one reactor went into a core meltdown, although that affected about 45 percent of the reactor core. The fuel stayed inside the reactor pressure vessel.
By way of contrast, meltdowns affected three reactors at the Fukushima No. 1 plant, and fuel leaked from the reactor containment vessels.
At Three Mile Island, the pressure vessel remained intact, making it possible to continue cooling the melted fuel by pumping water into it.
A major hurdle at the Fukushima No. 1 plant concerns how to fill the containment vessels with water.
Water is needed to shield against radiation and to cool down the fuel while the fuel is being removed. Assessing the extent of damage to the containment vessels and determining ways to repair them will prove key to decisions to be made in the months ahead.
During the operation to remove fuel at Three Mile Island that started in 1985, technicians stood on lead plates above the nuclear reactor and lowered a crane through openings between the plates. They were exposed to radiation doses of about 0.1 millisievert per hour, DeVine said.
In the case of Fukushima, more technicians may be required than at Three Mile Island. This is because different sorts of radiation hot spots dot the interiors of the reactor buildings, according to Roger Shaw, who helped oversee clean-up efforts at Three Mile Island in his capacity as a director of radiation protection.
It took more than four years to remove 99.5 percent of the fuel from the reactor building at Three Mile Island. The removal work finished in January 1990, after it was confirmed that the remaining 0.5 percent of the fuel, which had eluded recovery, was not going to reach re-criticality, or a sustained nuclear fission chain reaction.
At Three Mile Island, the basement of the reactor building remains inaccessible even now, with a radiation reading of about 10 millisieverts per hour. That is because radioactive water flooded the reactor building and permeated the structure during the crisis.
It cost $1 billion to remove the fuel. The Unit 2 reactor, together with Unit 1 that continues to operate, will be decommissioned in 2034.
"Given the fact there is so much rubble and other obstacles at the Fukushima No. 1 plant, more than 10 times the tasks undertaken at Three Mile Island may be waiting to be done at the Fukushima No. 1 plant," said Wataru Mizumachi, 69, chairman of the Expert Group on Occupational Radiation Protection in Severe Accident Management and Post-Accident Recovery under the International Atomic Energy Agency.
"But many lessons can still be learned from the experience in the United States, including how to develop equipment for fuel removal and how to store the fuel," added Mizumachi, who also took part in recovery work following the Three Mile Island meltdown.
When Gaming Is Good for You
Hours of Intense Play Change the Adult Brain; Better Multitasking, Decision-Making and Even Creativity
Videogames can change a person's brain and, as researchers are finding, often that change is for the better.
A growing body of university research suggests that gaming improves creativity, decision-making and perception. The specific benefits are wide ranging, from improved hand-eye coordination in surgeons to vision changes that boost night driving ability.
People who played action-based video and computer games made decisions 25% faster than others without sacrificing accuracy, according to a study. Indeed, the most adept gamers can make choices and act on them up to six times a second—four times faster than most people, other researchers found. Moreover, practiced game players can pay attention to more than six things at once without getting confused, compared with the four that someone can normally keep in mind, said University of Rochester researchers. The studies were conducted independently of the companies that sell video and computer games.
Scientists also found that women—who make up about 42% of computer and videogame players—were better able to mentally manipulate 3D objects, a skill at which men are generally more adept. Most studies looked at adults rather than children.
Electronic gameplay has its downside. Brain scans show that violent videogames can alter brain function in healthy young men after just a week of play, depressing activity among regions associated with emotional control, researchers at Indiana University recently reported. Other studies have found an association between compulsive gaming and being overweight, introverted and prone to depression. The studies didn't compare the benefits of gaming with such downsides.
The violent action games that often worry parents most had the strongest beneficial effect on the brain. "These are not the games you would think are mind-enhancing," said cognitive neuroscientist Daphne Bavelier, who studies the effect of action games at Switzerland's University of Geneva and the University of Rochester in New York.
Different Games' Effects on Your Brain
Learn how different games do different things to your brain
Computer gaming has become a $25 billion-a year entertainment business behemoth since the first coin-operated commercial videogames hit the market 41 years ago. In 2010, gaming companies sold 257 million video and computer games, according to figures compiled by the industry's trade group, the Entertainment Software Association.
For scientists, the industry unintentionally launched a mass experiment in the neurobiology of learning. Millions of people have immersed themselves in the interactive reward conditioning of electronic game play, from Tetris, Angry Birds, and Farmville, to shooter games and multiplayer, role-playing fantasies such as League of Legend, which has been played 1 billion times or so in the two years since it was introduced.
"Videogames change your brain," said University of Wisconsin psychologist C. Shawn Green, who studies how electronic games affect abilities. So does learning to read, playing the piano, or navigating the streets of London, which have all been shown to change the brain's physical structure. The powerful combination of concentration and rewarding surges of neurotransmitters like dopamine strengthen neural circuits in much the same the way that exercise builds muscles. But "games definitely hit the reward system in a way that not all activities do," he said.
"There has been a lot of attention wasted in figuring out whether these things turn us into killing machines," said computational analyst Joshua Lewis at the University of California in San Diego, who studied 2,000 computer game players. "Not enough attention has been paid to the unique and interesting features that videogames have outside of the violence."
Broadly speaking, today's average gamer is 34 years old and has been playing electronic games for 12 years, often up to 18 hours a week. By one analyst's calculation, the 11 million or so registered users of the online role-playing fantasy World of Warcraft collectively have spent as much time playing the game since its introduction in 2004 as humanity spent evolving as a species—about 50 billion hours of game time, which adds up to about 5.9 million years.

With people playing so many hundreds, if not thousands, of different games, though, university researchers have been hard-pressed to pinpoint the lasting effects on cognition and behavior.
Blizzard Entertainment Inc. in Irvine, Calif., which sells World of Warcraft, StarCraft II and other popular games, did not respond to queries about whether the company supports gaming research or conducts its own studies. Neither did RiotGames Inc. in Santa Monica, which markets League of Legends.
The vast majority of the research did not directly compare gaming with hours of other intense, mental activities such as solving math equations. Almost any computer game appears to boost a child's creativity, researchers at Michigan State University's Children and Technology Project reported in November.
A three-year study of 491 middle school students found that the more children played computer games the higher their scores on a standardized test of creativity—regardless of race, gender, or the kind of game played. The researchers ranked students on a widely used measure called the Torrance Test of Creativity, which involves such tasks as drawing an "interesting and exciting" picture from a curved shape on a sheet of paper, giving the picture a title, and then writing a story about it. The results were ranked by seven researchers for originality, length, and complexity on a standardized three-point scale for each factor, along with detailed questionnaires.
In contrast, using cellphones, the Internet, or computers for other purposes had no effect on creativity, they said.
"Much to my surprise, it didn't matter whether you were playing aggressive games or sport games, not a bit," said psychologist Linda Jackson, who led the federally funded study of 491 boys and girls at 20 Michigan schools.
Even so, researchers have yet to create educational software as engaging as most action games. Without such intense involvement, neural circuits won't change, they believe. "It happens that all the games that have the good learning effect happen to be violent. We don't know whether the violence is important or not," said Dr. Bavelier. "We hope not."
Until recently, most researchers studied the effects of gaming on small groups of volunteers, who learned to play under laboratory conditions. Some scientists now are turning the commercial games themselves into laboratories of learning.
In the largest public study of electronic gaming so far, Mark Blair at Simon Fraser University in Vancouver, British Columbia, is analyzing the behavior of 150,000 people who play the popular online game called StarCraft II, pulling together more than 1.5 billion data points of perception, attention, movement and second-by-second decision-making.
By analyzing so much game play, he hopes to learn how people become experts in an online world. That may shed light on how new knowledge and experience can become second nature, integrated into the way we react to the world around us.
