Environmental crises may threaten pensions

SAVE the planet, save your pension. A new report claims that environmental problems could bust pension funds by 2050.

Aled Jones of Anglia Ruskin University in Cambridge, UK, and his colleagues drew together evidence about a wide range of environmental problems, from water shortages to atmospheric pollution to climate change. They plugged these into models used to predict the values of pension funds.

Jones ran several scenarios, varying how quickly governments and industry responded to environmental problems. The results are published by the UK's Institute and Faculty of Actuaries (IFA). In almost all cases the value of funds began to fall before 2100. In the worst-case scenario, where governments and markets did nothing, values dropped steeply from around 2020 and fell to zero by 2050.

"Despite strong evidence that there is a risk that resource constraints could have significant economic impacts, these risks are not being factored in by many actors in the global economy," says Peter Tompkins of the IFA.

Venezuelans puzzle over official lingo on Chavez health crisis

CARACAS (Reuters) - Venezuela's bespectacled and shaven-headed information minister stands solemnly at the microphone to impart the latest news on President Hugo Chavez's cancer.

For a couple of minutes, vague descriptions of the patient's "stability", "progressive tendency" or "complications" waft across TV and radio airwaves into millions of Venezuelan homes.

"You see, he's recovering," says one Venezuelan man in a group watching live one of Information Minister Ernesto Villegas' medical updates, almost a national ritual since the socialist Chavez disappeared from public view six weeks ago.

"Rubbish - it's obvious he's dying," retorts another as the friends draw varying conclusions from the confusing report.

The handling of information over Chavez's condition has become as controversial as the man himself, and every official word is picked over ad nauseam in Venezuela's own version of the "Kremlinology" analysis of political minutiae in the former Soviet Union.

Since Chavez underwent his fourth and most serious cancer operation in Cuba on December 11, he has not spoken a word in public. The government has tried to fill the information void with regular communiques - nearly 30 so far - by Villegas and Vice-President Nicolas Maduro.

They are often tricky to interpret.

READING BETWEEN LINES

"President Chavez's state of health continues to be delicate, presenting complications that are being attended in a process not exempt of risk," read one statement just after Christmas, when there were rumors Chavez was on life support.

Some of the most specific have referred to Chavez's "breathing insufficiency" due to a lung infection. The term covers a large gamut of possibilities in Venezuelans' minds.

"The patient is in a state of progressive and favorable recovery of the normal values of his vital signs," said another communique, begging the question of what state he was in prior to that apparent upturn.

While the words "stability" and "progressive" have cropped up over and over, the first appearance of the word "stationary" in a January 7 communique puzzled some.

"The president finds himself in a stationary situation in relation to what was described in the most recent report," it read. "Treatment is being applied permanently and rigorously, and the patient is assimilating it," it added, without a word on what that treatment consisted of.

On Christmas Eve, mixing their messages, Villegas said Chavez was in "absolute rest" while Maduro assured Venezuelans a few hours later he was exercising. Of late, the communiques have become more optimistic about Chavez's "favorable evolution" and "new phase" with officials hinting at a possible homecoming.

Such language, critics say, is reminiscent of the confusion over various Russian leaders' illnesses, from Bolshevik revolutionary Vladimir Lenin's death in 1924 to a stream of others during the Cold War, or the secrecy-shrouded demise of former Spanish dictator Francisco Franco in 1975.

There is a parallel, too, with the official reticence in Cuba over the health problems of revolutionary leader Fidel Castro, who mentored Chavez and is his closest ally.

By contrast, other Latin American leaders who have in recent years suffered cancer - including from Brazil, Colombia and Paraguay - have authorized doctors to release full details.

At first, after being diagnosed with cancer in the pelvic region in mid-2011, Chavez was his own spokesman. His emotive personality always came through, fighting back tears when explaining the illness then brimming with joy at declarations of recovery that later proved wrong.

Yet throughout the speeches, there were few hard medical details, rather descriptions of a "baseball-sized tumor" or the "miracle" of recovery, and musings on his journey to the "abyss" laced with quotes from German thinker Friedrich Nietzsche.

INTERNET 'ORACLES'

Many Venezuelans have been going to unofficial internet "sources" to hunt for more about Chavez's health.

Most high-profile are Nelson Bocaranda, an opposition journalist and columnist with more than a million Twitter followers, and Jose Rafael Marquina, a Venezuelan doctor in Miami whose tweets alternate between complex medical terminology and caustic political attacks.

Both men claim close sources among the Cuban, Venezuelan and Brazilian doctors treating Chavez. But plenty of would-be Internet oracles have got it wrong - various forecasts and talk of Chavez's death have been premature and embarrassing.

Amid the barrage of opposition complaints over secrecy, the government says it has never been more open and lashes out at ill-intentioned "necrophiliacs" demanding more.

Opposition leaders want an independent medical committee to travel to Havana to see if Chavez is fit to continue in power. If not, he would have to hand over to a caretaker president prior to a new election as mandated by the constitution.

One group of humorists sought to lighten the grave national mood - and lampoon officials - with a merciless take on the Villegas-Maduro information double act.

"Commander Chavez is stable in that situation I won't tell you about," its spoof Villegas said. "He requires unspecified treatment to calm supposed problems that could affect him, or not, in the place of the illness, I mean, that thing."

They were no less biting with Maduro, putting into his mouth a phrase reminiscent of English writer George Orwell's famous send-up of totalitarianism in the book 'Animal Farm': "The president is stable, some days less stable, some days more stable, and sometimes in a state of excessive stability."

Such mockery infuriates Chavez's allies, who say opponents and foreign media are showing glee at his suffering.

One pro-government analyst acknowledged officials had been less than forthcoming, but said they were entitled to be given the "warlike" atmosphere in Venezuela, where opposition leaders spent years trying to force Chavez from office through national strikes, a failed coup and an oil industry shutdown.

Villegas himself described the mood as similar to the brief putsch against Chavez in April of 2002, when foes exulted while supporters trusted in the president's return.

"No one believed it and they said we were liars," said Villegas, who worked at state TV at the time. "Then he came back, took out his crucifix and spoke. It can happen just like that again you know, friends."

Healthy Exercise vs. Compulsive Exercise | Libero Network

Post - Guest - Fitspiration

You may be engaging in a healthy amount of exercise (or you might be over- exercising as well), but the thought processes behind it are still damaging.Being motivated to exercise purely as a means to burn calories, as opposed to improving the health of your body is a red flag.


?Exercise is good for you. You?re not doing anything wrong, keep exercising. It will make you fit and strong and lean. You?re not exercising too much, those other people are just jealous. You?re only feeling tired because you?re so unfit, exercise more. You have to work hard if you want results.?

That was what my ED said to me day in and day out to keep me trapped and compulsively exercising. I know now that voice was lying. I work as an exercise scientist, personal trainer and group fitness instructor and study exercise physiology at university so a very large portion of my life revolves around exercise.

When I first started exercising, I genuinely loved and enjoyed it, but as my ED developed it began to use this to its advantage. I began exercising excessively and obsessively, yet despite all my own knowledge about exercise I still wasn?t open to the thought that I was doing anything unhealthy and denied it when anyone asked.

Exercise, as a general rule, is good for you. However, there are two factors which shift exercise from the ?good for your health? to the ?bad for your health? basket: exercising to the detriment of your body and exercising to the detriment of your mind.

1. Exercising to the detriment of your body is the result of the amount of exercise you?re doing and the lack of recovery your body is receiving.

At this point, you might even still be enjoying exercising (as I was at the beginning) however your body will eventually begin to feel tired, sore and weak. You may experience dizzy spells, fainting, irregular or absent menstrual cycles, difficulty sleeping, increased injuries or illness. The amount of exercise that is healthy will vary from person to person ? what is healthy for an iron man isn?t healthy for me. My ED told me that the amount of exercise I was doing was perfectly healthy, because athletes do it and they?re healthy. Athletes also gradually build up to that level over many years, they fuel their bodies appropriately, they have regular recovery sessions and they stop or reduce exercise when injured/sick.

2. Exercising to the detriment of your mind develops because of reasons why you are exercising and the thoughts behind it.

You may be engaging in a healthy amount of exercise (or you might be over- exercising as well), but the thought processes behind it are still damaging. Being motivated to exercise purely as a means to burn calories, as opposed to improving the health of your body is a red flag. If you are consistently prioritizing exercise over social situations/study/work, feeling anxious or guilty at the thought of missing an exercise session, exercising because you ?have to? rather than because you ?want to? and/or spending a large amount of time thinking about or planning exercise, it is likely that you?ve developed an unhealthy obsession with exercise that leaves little room in your thoughts and life for other things.

Signs that you may be compulsively exercising or over-training:

  • Irregular or absent menstrual cycles
  • Depression
  • Difficulty sleeping
  • Muscle soreness, aches and injuries
  • Prioritizing exercise over social events/work/study
  • Exercising despite being sick or injured
  • Inability to miss an exercise session or feeling guilty for missing an exercise session
  • Exercising because you ?have to? rather than because you ?want to?
  • Exercising purely to burn calories
  • Consistently thinking about exercise
  • Exercising at inappropriate times (eg middle of the night)

So, what is healthy exercise?

Healthy exercise occurs when we exercise because it makes us feel good, physically, emotionally and mentally. As mentioned earlier, it?s difficult to set general guidelines on what constitutes the right amount of exercise for everyone; for most people 2-5 hours per week is an appropriate range. However, with some thought and listening to your body (and maybe some professional advice) you can determine the healthiest amount of exercise for you.

Signs of healthy exercise

  • Exercise makes you feel good ? physically, mentally and emotionally
  • You can take a day/week/month off of exercise without feeling anxious or guilty
  • You rest and recover if you are sore, injured, tired or sick
  • You engage in physical activity that you enjoy (walking, dancing, kayaking, cycling etc), rather than the type you think you should do/burns the most calories
  • You allocate no more time to thinking about exercise than you would to household chores or what?s on television
  • You are comfortable with missing an exercise session to attend a social event/work/study
  • You think about exercise as a way to keep your mind and body fit, strong and healthy; as opposed to simply a way to burn calories or change your body shape

?

At times, I still battle with compulsive exercising; recovery takes time and I have my slip ups, but I?ve come a long way from where I used to be. I can now recognize when I?m engaging in ED behaviours. I always find it helpful to think about what advice I would give to a friend about healthy exercise and aim to apply that advice to myself.

Technicolor Options Rights to Graphic Novel Series ?The Deep ...

This press release that arrived in the inbox this morning was interesting to me because I wasn?t aware that Technicolor, which has a long and illustrious history as a technology company, is making a push into original content development. In addition to The Deep, they are developing Berkeley Breathed?s Pete & Pickles, and Atomic Puppet, a co-production with Mercury Filmworks. Should these projects move forward, the animation would be produced at Technicolor?s studio in Bangalore, India.

Paris (France) ? January 22, 2013 ? Technicolor (Euronext Paris: TCH) has optioned the rights for the international hit graphic novel series, THE DEEP, created by writer Tom Taylor (Star Wars: Blood Ties, Batman: Legends of the Dark Knight, Injustice: Gods Among Us) and illustrator James Brouwer (Justice League Beyond), and published by Gestalt Comics.

The Deep: Here Be Dragons graphic novel won the Aurealis Award (Australia?s annual literary awards for science fiction, fantasy and fiction) for ?Best Illustrated Book / Graphic Novel? of 2011 and was also nominated for ?Best Children?s Fiction (illustrated).? Technicolor Digital Productions aims to develop and produce 26 half-hour episodes of THE DEEP, which follows the incredible adventures of a family of underwater explorers. The CGI-animated series targets Kids 8 ? 12 and their families. Each self-contained episode of THE DEEP will bring the family a step closer to unraveling the mysteries of the deep sea; and every story will be filled with action, adventure, incredible sea monsters, fantastic vehicles, unbelievable bravery, and the odd family squabble, of course!

?THE DEEP is one of those unique properties that truly appeals to all ages and genders by delivering compelling entertainment in the form of enthralling adventure, heart-pounding danger, laugh out loud humor and incredible discoveries all wrapped in unbreakable familial relationships,? said Steven Wendland, Vice President, Technicolor Digital Productions. ?It?s the family we all dreamed of being a part of when we were kids and are anxious and excited to share with our own children now.?

?Technicolor is the ideal animation studio to bring THE DEEP to life,? added Robert Chandler, Executive Producer, THE DEEP. ?The CG team at Technicolor has the ability not only to visually knock your socks off, but also to deliver moments of tenderness, character and heart. That?s why THE DEEP and Technicolor make a great partnership. It is that special combination which leads to creating great series and stories.?

THE DEEP follows the Nekton family, comprised of the independent and fearless 12 year old Antaeus, Ant to his friends; his analytical 15 year old sister Fontaine, an astute navigator; and their parents Will, an oceanographer and former Olympic swimmer, and Kaiko, a marine biologist who is fiercely protective of all sea life, including Ant?s pet fish, Jeffrey. Continuing a long family legacy, the Nektons live aboard a state of the art submarine, The Aronnax, while exploring unchartered areas of the earth?s oceans. Each member of the family has unique skills and are all equally passionate about sea life conservation. They seek to solve the ultimate mysteries that appear to be connected to a place we know as Atlantis.

THE DEEP was created by multi-award-winning playwright, screenwriter and author Tom Taylor, best known for his many Star Wars graphic novels and comic books for Lucasfilm and Dark Horse Comics; and illustrator James Brouwer who has worked as a pre-production and concept artist on a range of film, television and games projects for major studios. Brouwer moved into comics in 2011 with The Deep: Here Be Dragons and has since illustrated for DC Comics.

Technicolor Digital Productions produces high-quality CG animation for feature films, television, direct-to-video, commercials, video games and location-based entertainment through its industry-leading production facility in Bangalore, India. The group launched its original content development initiative in 2010 and is currently in development on several projects, including Berkeley Breathed?s Pete & Pickles, and Atomic Puppet, a co-production with Mercury Filmworks. Complementing its services business with original content creation, Technical Digital Productions continues to work with major animation clients including Nickelodeon, DreamWorks Animation, Electronic Arts, Mattel, Rockstar Games, Sony Computer Entertainment America and Square Enix.

Penguins are 'efficient' killers

In this clip, head-mounted cameras show penguin behaviour

Intimate details of Adelie penguin feeding behaviour have been filmed by Japanese scientists.

Using video cameras and accelerometers attached to free-swimming penguins, researchers have gained a unique insight into the birds' hunting techniques.

Adelie penguins adopted different strategies depending on whether they were hunting fish or krill.

The findings are published in the journal PNAS.

Lead scientist Dr Yuuki Watanabe from the National Institute of Polar Research in Tokyo, Japan, told BBC Nature: "Foraging is the most basic activity of animals, but details of foraging behaviour are poorly known, especially in marine animals."

Although previous studies had examined Adelie penguin's (Pygoscelis adeliae) foraging style using video apparatus or sensor technology, results were limited.

"Previously some researchers attached video cameras to marine animals to observe their foraging behaviour, but this was just a few hours."

"In other studies, researchers attached various sensors to marine animals to record indirect signals of prey capture. This method lasted for long periods, but has never been validated in the field," said Dr Watanabe.

To overcome these difficulties, the Japanese scientists decided to use a combination of video footage and indirect signals.

Indirect signals include acceleration of the head, temperature changes in the digestive tract or beak opening movements, all of which indicate that feeding may have occurred.

Modern technologies mean that accelerometers are small enough for the scientists to attach two accelerators to each penguin - one on the head and another on the back.

"We recorded both movies and indirect signals, successfully validating the indirect signals using video footage," explained Dr Watanabe.

"We assumed that penguins move their heads relative to their body when they capture prey; this was confirmed by the footage."

Using these methods the team was able to ascertain when and how the penguins were feeding.

Fast food

With the results of the combined technologies, scientists were able to draw further conclusions about the Adelie penguins' feeding strategy.

The penguins' foraging area is largely covered by marine ice and their primary food sources include two species of krill and Pagothenia borchgrevinki - a fish whose blood contains antifreeze proteins.

The Antarctic krill (Euphausia superba) is a shrimp-like crustacean that grows to approximately 6cm long. Antarctic coastal krill (E. crystallorophias) lives farther south than any other species of krill.

Krill is an important part of the Antarctic ecosystem, with around half of its biomass being consumed annually by marine predators such as penguins, squid, whales and fish.

When capturing krill, the penguins swam upward then changed direction at the point of predation, making darting movements with their head.

The team discovered that Adelie penguins can catch krill at a rate of up to two krill per second, despite krill displaying escape behaviours.

Furthermore the researchers found that the camouflage defence of the fish P. borchgrevinki didn't work with foraging Adelie penguins.

The penguins were regularly able to capture the fish from below - the direction from which the fish is camouflaged against the backdrop of marine ice.

Dr Watanabe said: "I was surprised by how the penguins repeatedly captured P. borchgrevinki underneath the sea ice. This fish is known to be well camouflaged."

The technology used to support the findings has a wider application for further study. Dr Watanabe commented, "Our method can be applied to many marine animals to understand the spatial and temporal variability of foraging behaviour."
