Dell Rapids St Mary Recognized as an ?Outstanding? High School ...

The South Dakota High School Activities Association (SDHSAA) announced that 31 South Dakota high school student councils have been recognized as being ?Outstanding Student Councils? for the 2012-13 school year. This is the 23rd year this statewide program has been sponsored by the SDHSAA to recognize those South Dakota high school student councils that meet or exceed the rigorous standards of excellence that are necessary to achieve the ?Outstanding Student Council? designation. Student councils that achieve this recognition can best be described as being very active within their school and community throughout the school year. Outstanding Councils excel in having a well-rounded program of activities and projects which benefit both their school and their community throughout the school year.

The ?SDHSAA Outstanding Student Council? program requires each participating student council to complete a self-evaluation of their organizational structure and their successful completion of projects in a variety of areas. The evaluation also considers the involvement of the student council in their school and community. James Weaver, SDHSAA Assistant Executive Director, stated ?The High School Activities Association recognizes the student councils that have met the stringent standards and criteria demanded by this program. The 31 student councils that have been recognized this year, are well organized, highly motivated and have met the rigorous standards necessary to be declared outstanding. The self-evaluation focuses on the structure of the student council as well as the positive involvement of the student council in the activities of their school and community.?

To be recognized as an ?Outstanding Student Council?, each council was involved in projects in the areas such as ?Community and School Service?, ?Health, Safety or Chemical Awareness?, ?Education?, ?Leadership?. Completion of projects in a wide range of areas was necessary to fulfill a variety of goals for the student council. Each school receiving the ?SDHSAA Outstanding Student Council? award has demonstrated a desire for self-improvement and individual growth by participating in leadership workshops and conventions, as well as other educational programs.

The 2012-13 ?SDHSAA Outstanding Student Council? Award recipients are:

  • Aberdeen Central High School ? Advisor: Kevin Rook

Robotic ants successfully mimic real colony behavior

Mar. 28, 2013 ? Scientists have successfully replicated the behaviour of a colony of ants on the move with the use of miniature robots, as reported in the journal PLOS Computational Biology. The researchers, based at the New Jersey Institute of Technology (Newark, USA) and at the Research Centre on Animal Cognition (Toulouse, France), aimed to discover how individual ants, when part of a moving colony, orient themselves in the labyrinthine pathways that stretch from their nest to various food sources.

The study focused mainly on how Argentine ants behave and coordinate themselves in both symmetrical and asymmetrical pathways. In nature, ants do this by leaving chemical pheromone trails. This was reproduced by a swarm of sugar cube size robots, called "Alices," leaving light trails that they can detect with two light sensors mimicking the role of the ants' antennae.

In the beginning of the experiment, where branches of the maze had no light trail, the robots adopted an "exploratory behaviour" modelled on the regular insect movement pattern of moving randomly but in the same general direction. This led the robots to choose the path that deviated least from their trajectory at each bifurcation of the network. If the robots detected a light trail, they would turn to follow that path.

One outcome of the robotic model was the discovery that the robots did not need to be programmed to identify and compute the geometry of the network bifurcations. They managed to navigate the maze using only the pheromone light trail and the programmed directional random walk, which directed them to the more direct route between their starting area and a target area on the periphery of the maze. Individual Argentine ants have poor eyesight and move too quickly to make a calculated decision about their direction. Therefore the fact that the robots managed to orient themselves in the maze in a similar fashion than the one observed in real ants suggests that a complex cognitive process is not necessary for colonies of ants to navigate efficiently in their complex network of foraging trails.

"This research suggests that efficient navigation and foraging can be achieved with minimal cognitive abilities in ants," says lead author Simon Garnier. "It also shows that the geometry of transport networks plays a critical role in the flow of information and material in ant as well as in human societies."

Singer Michelle Shocked sits in at canceled show

SANTA CRUZ, Calif. (AP) ? Face covered and mouth taped shut, alternative folk and rock singer Michelle Shocked staged a sit in outside a Santa Cruz nightclub that canceled her show because she made an anti-gay slur at a San Francisco club earlier this month.

The tape across her mouth said "Silenced By Fear." When asked a question, Shocked shook her head vigorously and strummed her guitar while seated on the ground outside popular music venue Moe's Alley. She pointed to a sign inviting people to pick up a Sharpie marker and write on the white disposable safety suit she was wearing.

Earlier in the day, she had tweeted her plans: "Moe's in S Cruz tonight ok? Its an art project 'My Summer Vacation' I want your autograph. Bring Sharpie."

Moe's Alley owner Bill Welch, who talked with Shocked as she strummed her guitar outside his club, had replaced her with bands Beaver Fever and Frootie Flavors.

"We will not be bashing Michelle Shocked," he said. "Rather we will celebrate music, diversity and send some healing Santa Cruz energy her way."

How diabetes drug delays aging in worms

Mar. 28, 2013 ? A widely prescribed type 2 diabetes drug slows down the aging process by mimicking the effects of dieting, according to a study published today using worms to investigate how the drug works.

Following a calorie-restricted diet has been shown to improve health in later life and extend lifespan in a number of animals, ranging from the simple worm to rhesus monkeys. The type 2 diabetes drug metformin has been found to have similar effects in animals but until now it was not clear exactly how the drug delays the aging process.

Researchers supported by the Wellcome Trust and Medical Research Council looked at the effects of metformin on C. elegans worms that were grown in the presence of E. coli bacteria, a relationship similar to that which humans have with the 'healthy' bacteria in our gut. They found that the worms treated with metformin lived longer only when the E. coli strain they were cultured with was sensitive to the drug.

Dr Filipe Cabreiro from the Institute of Healthy aging at UCL, who led the research, explains: "Overall, treatment with metformin adds up to 6 days of life for the worm which is equivalent to around a third of its normal lifespan. It seems to work by altering metabolism in the bacteria that live in the worm, which in turn limits the nutrients that are available to the worm host and has a similar effect to restricting the diet."

Bacteria living in the gut have an important role in helping the host organism to digest and extract nutrition from food. Defects in gut bacteria have been linked to metabolic diseases such as obesity, diabetes, inflammatory bowel disease and cancer. It has also been suggested that gut bacteria may have an impact on the aging process, but this is the first study to suggest a mechanism for how this works.

The team used strains of E. coli with defects in genes that are linked to metabolism and tweaked the levels of nutrients available to tease out which metabolic pathways might be affected by the drug. They found that treatment with metformin disrupted the bacteria's ability to metabolise folate, a type of B-vitamin, and methionine, one of the building blocks of proteins. This limits the nutrients that are available to the worm and mimics the effects of dietary restriction to enable the worms to live longer.

However, when they added an excess of sugar to the diet, the team found that the life-extending effects of metformin were cancelled out. As the drug is used as a treatment for diabetes caused by elevated glucose levels in the blood, this finding is particular relevant for understanding how the drug works in people.

Professor David Gems, who directed the study, said: "We don't know from this study whether metformin has any effect on human aging. The more interesting finding is the suggestion that drugs that alter bacteria in the gut could give us a new way of treating or preventing metabolic diseases like obesity and diabetes."

Metformin is currently one of the most widely prescribed drugs and the findings should help to inform how it is used in patients.

Former U.S. soldier accused of fighting with al Qaeda in Syria

WASHINGTON (Reuters) - A former U.S. soldier was arrested and charged with conspiring to use a rocket-propelled grenade while fighting with an al Qaeda affiliate in Syria against the forces of Syrian President Bashar al-Assad, U.S. prosecutors said on Thursday.

Eric Harroun, 30, of Phoenix, Arizona, was accused of fighting with the al-Nusrah Front, also known as al Qaeda in Iraq, which is designated by the United States as a foreign terrorist organization, the U.S. Attorney for the Eastern District of Virginia and the FBI said in a joint statement.

Even as U.S. officials call for Assad to step down in Syria and seek to support the rebels, they have expressed concern about militant groups like al Qaeda affiliates gaining a foothold in Syria.

Harroun served with the U.S. Army from 2000 to 2003 and was medically discharged after being injured in a car accident, according to an affidavit in support of a criminal complaint.

The criminal charge of "conspiring to use a destructive device outside of the United States" carries a maximum penalty of life in prison.

Harroun was arrested on Wednesday upon returning to the United States at an airport outside Washington and made his initial appearance in federal court in Virginia on Thursday. He has a hearing scheduled for Tuesday, the U.S. Attorney's office said.

Harroun is accused of crossing into Syria in January and fighting with members of the al-Nusrah Front against Assad's forces, the affidavit said. Al-Nusrah is said by U.S. officials to be the best-organized and most effective armed Syrian opposition group.

He was allegedly trained to use the weapon by members of the al Qaeda affiliate and is accused of firing it, participating in attacks, and posting multiple photographs of himself carrying or posing with rocket-propelled grenades and other weapons, the U.S. government said.

Harroun appeared in two videos that indicated he was engaged in military action with rebel forces against the Syrian government, and in one video he said: "Bashar al-Assad, your days are numbered. ... Where(ever) you go we will find you and kill you," according to the affidavit.

In March, the FBI conducted three voluntary interviews of Harroun at the U.S. Consulate in Istanbul, during which he stated that he wanted to fight with the Free Syrian Army against the Assad regime, the affidavit said.

In one incident, Harroun and other members of the Free Syrian Army allegedly engaged in a joint attack with the al-Nusrah Front on a Syrian army encampment, the affidavit said.

Harroun allegedly told the FBI that during his fighting in Syria he shot about 10 people but did not know whether he killed any of them, the affidavit said. He also said he hated al Qaeda and did not know any al Qaeda members, the affidavit said.

On Wednesday in the United States, the FBI conducted another voluntary interview during which Harroun allegedly said that he knew the al-Nusrah Front had been designated a terrorist organization, according to the affidavit.

The U.S. Attorney's office said a lawyer would be appointed for Harroun.

Police: No sign of 3rd party in Berezovsky death

British police officers cordon off a road near a residence in Ascot, a town 40 kilometers (25 miles) west of London, Saturday, March 23, 2013. Boris Berezovsky, 67, a self-exiled and outspoken former Russian oligarch who had a bitter falling out with Russian President Vladimir Putin, was found dead Saturday in southeast England. Thames Valley police said his death was being treated as unexplained. They would not directly identify him, but when asked about him by name they read a statement saying they were investigating the death of a 67-year-old man at a property in Ascot. A mathematician turned Mercedes dealer, Berezovsky amassed his wealth during Russia's chaotic privatization of state assets in the early 1990's. The one-time Kremlin powerbroker fell out with Putin and sought political asylum in Britain in the early 2000's. He has lived in the U.K. ever since. (AP Photo/Lefteris Pitarakis)

(AP) ? British police said Sunday they have no evidence to suggest third-party involvement in the death of Boris Berezovsky, the self-exiled Russian tycoon who went from Kremlin kingmaker to fiery critic.

With an investigation underway, police are treating the death of Berezovsky ? who fled to Britain in the early 2000s after a bitter falling out with Russian President Vladimir Putin ? as unexplained. But the former oligarch survived assassination attempts and recently faced financial difficulties, prompting speculation as to whether his death was part of a conspiracy ? or suicide.

Police said Sunday it would be wrong to speculate on how Berezovsky died pending the results of an autopsy but that they had no reason to suspect

"We are at the early stages of the investigation and we are retaining an open mind as we progress," said Detective Chief Inspector Kevin Brown. "The investigation team is building a picture of the last days of Mr. Berezovsky's life, speaking to close friends and family to gain a better understanding of his state of mind."

Police released some details on the circumstances that triggered their investigation into his demise and a subsequent check for hazardous materials at the property in Ascot, a town 40 kilometers (25 miles) west of London where Berezovsky's body was found on Saturday.

A call came into police from the local ambulance service at 3:23 p.m. GMT (11:23 a.m. EDT) Saturday saying a man had been found dead, Thames Valley Police said in a statement on Sunday.

The police said an employee of Berezovsky told how he had called an ambulance after becoming concerned for Berezovsky's welfare and forced open a bathroom door locked from the inside to find the tycoon's body on the floor.

The employee was the only person in the house when Berezovsky's body was discovered, police said. Members of the ex-oligarch's family arrived at the home while the paramedic was on scene.

Police explained that after a paramedic declared Berezovsky dead and left the scene, a device measuring his exposure to radiation was triggered, which is why chemical and radiations experts were called to examine the property.

"Officers found nothing of concern in the property and we are now progressing the investigation as normal," a statement from police said earlier, adding that the majority of the cordon put in place around the property has now been lifted.

Berezovsky ? who had survived a number of assassination attempts ? amassed a fortune through oil and automobiles during Russia's chaotic privatization of state assets following the collapse of the Soviet Union in the early 1990s.

Once a member of Russian President Boris Yeltsin's inner circle, Berezovsky fell out with Yeltsin's successor, Putin, and fled Britain in the early 2000s to escape fraud charges that he said were politically motivated.

He became a strident and frequent critic of Putin, accusing the leader of ushering in a dictatorship, and accused the security services of organizing the 1999 apartment house bombings in Moscow and two other Russian cities that became a pretext for Russian troops to sweep into Chechnya for the second war there in half a decade.

Putin's spokesman acknowledged Sunday that the Russian president considered Berezovsky an enemy with clearly stated intentions to fight.

"We know for certain that he spared no expense in support of processes, within Russia and beyond, that could be said to have been directed against Russia and Putin," spokesman Dmitry Peskov said on the independent cable television channel Rain. "He definitely was Putin's opponent, and unfortunately not only his political opponent, but most likely in other dimensions as well."

In recent years, Berezovsky fended off legal attacks that often bore political undertones ? and others that bit into his fortune.

Russia repeatedly sought to extradite on Berezovksy on a wide variety of criminal charges, and the tycoon vehemently rejected allegations over the years that he was linked to several deaths, including that of slain journalist Anna Politkovskaya and ex-KGB agent Alexander Litvinenko.

Berezovsky won a libel case in 2010 against a Kremlin-owned broadcaster that aired a show in which it was suggested he was behind the poisoning of Litvinenko, who had fled Russia with Berezovsky's help after accusing officials there of plotting to assassinate political opponents.

He took a hit with his divorce from Galina Besharova in 2010, paying what was at the time Britain's largest divorce settlement. The figure beat a previous record of 48 million pounds ($73.1 million) and was estimated as high as 100 million pounds, though the exact figure was never confirmed.

Last year, Berezovsky lost a multibillion-pound High Court case against fellow Russian Roman Abramovich and was ordered to pay 35 million pounds ($53.3 million) in legal costs.

Berezovsky had claimed that Abramovich, the billionaire owner of Chelsea Football Club, cheated him out of his stakes in the oil group Sibneft, arguing that he blackmailed him into selling the stakes vastly beneath their true worth after he lost Putin's good graces.

But a judge threw out the case in August, ruling that Berezovsky was a dishonest and unreliable witness, and rejected Berezovsky's claims that he was threatened by Putin and Alexander Voloshin, a Putin ally, to coerce him to sell his Sibneft stake.

It also recently emerged that Berezovsky ran up legal bills totaling more than 250,000 pounds in just two months of a case against his former partner, Elena Gorbunova, with whom he had two children and who claimed the businessman owed her millions.

Earlier this week, The Times of London newspaper reported that Berezovsky was selling property ? including an Andy Warhol portrait of the former Soviet Union leader Vladimir Lenin ? to settle his debts and pay expenses owed to lawyers.

News of Berezovsky's death has prompted conspiracy theories along with speculation as to his state of mind, given his recent financial setbacks.

Ilya Zhegulev, a journalist with the Russian edition of Forbes magazine, said he spoke with Berezovsky the day before he died and discussed the tycoon's decision to flee Russia in 2000.

The journalist quoted Berezovsky as saying that during his years in London he had lost the meaning of life.

"I no longer want to be involved in politics," Zhegulev quoted Berezovsky as saying in a story published Saturday on the Forbes.ru website.

He said Berezovsky told him that he wanted nothing more than to return to Russia. The former oligarch said he had changed his views on Russia, saying he now understood that it should not look to Europe as a model.

"I had absolutely, idealistically imagined that it was possible to build a democratic Russia. And idealistically imagined what democracy was in the center of Europe. I underestimated the inertia of Russia and greatly overestimated the West. This took place gradually. I changed my understanding of Russia's path," he quoted Berezovsky as having said.

Stunning new view of 'oldest light'

A spectacular new map of the "oldest light" in the sky has just been released by the European Space Agency.

Scientists say its mottled pattern is an exquisite confirmation of our Big-Bang model for the origin and evolution of the Universe.

But there are features in the picture, they add, that are unexpected and will require ideas to be refined.

The map was assembled from 15 months' worth of data acquired by the 600m-euro (?515m) Planck space telescope.

It details what is known as the cosmic microwave background, or CMB - a faint glow of microwave radiation that pervades all of space.

Its precise configuration, visible in the new Planck data, is suggestive of a cosmos that is slightly older than previously thought - one that came into existence 13.82 billion years ago.

This is an increase of about 50 million years on earlier calculations.

The map's pattern also indicates a subtle adjustment is needed to the Universe's inventory of contents.

It seems there is slightly more matter out there (31.7%) and slightly less "dark energy" (68.3%), the mysterious component thought to be driving the cosmos apart at an accelerating rate.

"I would imagine for [most people] it might look like a dirty rugby ball or a piece of modern art," said Cambridge University's George Efstathiou, presenting the new picture here at Esa headquarters in Paris.

"But I can assure you there are cosmologists who would have hacked our computers or maybe even given up their children to get hold of this map, we're so excited by it."

Planck is the third western satellite to study the CMB. The two previous efforts - COBE and WMAP - were led by the US space agency (Nasa). The Soviets also had an experiment in space in the 1980s that they called Relikt-1.

How Planck's view hints at new physics

  • The CMB's temperature fluctuations are put through a number of statistical analyses
  • Deviations can be studied as a function of their size on the sky - their angular scale
  • When compared to best-fit Big Bang models, some anomalies are evident
  • One shows the fluctuations on the biggest scales to be weaker than expected
  • Theorists will need to adjust their ideas to account for these features

The CMB is the light that was finally allowed to spread out across space once the Universe had cooled sufficiently to permit the formation of hydrogen atoms - about 380,000 years into the life of the cosmos.

It still bathes the Earth in a near-uniform glow at microwave frequencies, and has a temperature profile that is just 2.7 degrees above absolute zero.

But it is possible to detect minute deviations in this signal, and these fluctuations - seen as mottling in the map - are understood to reflect the differences in the density of matter when the light parted company and set out on its journey all those years ago.

The fluctuations can be thought of as the seeds for all the structure that later developed in the cosmos - all the stars and galaxies.

Scientists subject the temperature deviations to a range of statistical analyses, which can then be matched against theoretical expectations.

This allows them to rule in some models to explain the origin and evolution of the cosmos, while ruling out a host of others.

The team that has done this for Planck's data says the map is an elegant fit for the standard model of cosmology - the idea that the Universe started in a hot, dense state in an incredibly small space, and then expanded and cooled.

At a fundamental level, it also supports an "add-on" to this Big Bang theory known as inflation, which postulates that in the very first moments of its existence the Universe opened up in an exponential manner - faster than light itself.

But because Planck's map is so much more detailed than anything previously obtained, it is also possible to see some anomalies in it.

One is the finding that the temperature fluctuations, when viewed across the biggest scales, do not match those predicted by the standard model. Their signal is a bit weaker than expected.

  • 4.9% normal matter - atoms, the stuff from which we are all made
  • 26.8% dark matter - the unseen material holding galaxies together
  • 68.3% dark energy - the mysterious component accelerating cosmic expansion
  • The number for dark energy is lower than previously estimated
  • The new age - 13.82 billion years - results from a slower expansion
  • This is described by a value known as the Hubble Constant
  • It too is revised to 67.15 km per second, per megaparsec (3.2 million light-years)

There appears also to be an asymmetry in the average temperatures across the sky; the southern hemisphere is slightly warmer than the north.

A third significant anomaly is a cold spot in the map, centred on the constellation Eridanus, which is much bigger than would be predicted.

These features have been hinted at before by Planck's most recent predecessor - Nasa's WMAP satellite - but are now seen with greater clarity and their significance cemented.

A consequence will be the binning of many ideas for how inflation propagated, as the process was first introduced in the 1980s as a way to iron out such phenomena.

The fact that these delicate features are real will force theorists to finesse their inflationary solutions and possibly even lead them to some novel physics on the way.

"Inflation doesn't predict that it should leave behind any kind of history or remnant, and yet that's what we see," Planck project scientist Dr Jan Tauber told BBC News.

CMB - The 'oldest light' in the Universe

  • Theory says 380,000 years after the Big Bang, matter and light "decoupled"
  • Matter went on to form stars and galaxies; the light spread out and cooled
  • The light - the CMB - now washes over the Earth at microwave frequencies
  • Tiny deviations from this average glow appear as mottling in the map (above)
  • These fluctuations reflect density differences in the early distribution of matter
  • Their pattern betrays the age, shape and contents of the Universe, and more

NY approves Cornell Tech's applied sciences campus on Roosevelt Island

DNP Cornell Tech's plan for an applied sciences campus on Roosevelt Island has been approved

While Cornell has given its researchers the resources to build spider-like robots and move Pong paddles with the power of the mind, students more interested in the software side of engineering have not been getting as much love. That's about to change, however, with the recent City Planning Commission approval of Cornell Tech, a project to build an applied sciences campus on New York City's Roosevelt Island. Now the next step would be to get a blessing from the City Council. After all is said and done, we'll hopefully see the 12-acre site break ground in 2014, the campus opening its doors in 2017 and a full build-out by 2037. As they await their new home, Cornell is holding classes for aspiring computer whiz-kids at Google's Chelsea campus, where we're sure they'll get an inspiration or two. To see what else Cornell Tech has in store, check out the source link below.

In schizophrenia, deficits have been particularly well-described for a subtype of GABA neuron, the parvalbumin fast-spiking interneurons. The activity of these neurons is critical for proper cognitive and emotional functioning. It now appears that parvalbumin neurons are particularly vulnerable to oxidative stress, a factor that may emerge commonly in development, particularly in the context of psychiatric disorders like schizophrenia or bipolar disorder, where compromised mitochondrial function plays a role.Wed, 13 Mar 2013 09:55:55 EDThttp://www.sciencedaily.com/releases/2013/03/130313095533.htmAutistic children may be at greater risk of suicide ideation and attemptshttp://www.sciencedaily.com/releases/2013/03/130312152049.htm Children with an autism spectrum disorder may be at greater risk for contemplating suicide or attempting suicide than children without autism, according to researchers.Tue, 12 Mar 2013 15:20:20 EDThttp://www.sciencedaily.com/releases/2013/03/130312152049.htm'I don't want to pick!'

Research demonstrates how the brain homes in on one speaker to solve this "Cocktail Party Problem." Researchers discovered that brain waves are shaped so the brain can selectively track the sound patterns from the speaker of interest while excluding competing sounds from other speakers. The findings could have important implications for helping individuals with a range of deficits.Wed, 06 Mar 2013 13:42:42 ESThttp://www.sciencedaily.com/releases/2013/03/130306134218.htmFamily intervention improves mood symptoms in children and adolescents at risk for bipolar disorderhttp://www.sciencedaily.com/releases/2013/03/130306084154.htm Psychologists have found that children and adolescents with major depression or subthreshold forms of bipolar disorder - and who had at least one first-degree relative with bipolar disorder - responded better to a 12-session family-focused treatment than to a briefer educational treatment.Wed, 06 Mar 2013 08:41:41 ESThttp://www.sciencedaily.com/releases/2013/03/130306084154.htmHelp in reading foreign languageshttp://www.sciencedaily.com/releases/2013/03/130306083935.htm Recent research into how we learn is set to help people in their efforts to read a second or foreign language (SFL) more effectively.

Player lives on as character in favorite game after losing cancer battle

A gamer who lost his life to cancer will be memorialized in the latest version of the "Total War" series of games ? his favorite, and the creators of which he was able to pay a visit thanks to a local charity.

The player, James (whose last name was withheld for his family's privacy) had liver cancer, and was told in mid-2012 that he had only a few months to live. He was a huge fan of the "Total War" series of games. Charity organization The Willow Foundation arranged it so that last summer, James, 24, could stop by Creative Assembly's studios in Horsham, U.K., where the games are developed.

As it turned out, the latest game in the franchise, "Rome: Total War II," was announced the day before James's visit. The Creative Assembly team was "moved, and humbled" by their fan's passion and knowledge of their games, and James was allowed to be the first person to play the new game, taking part in the siege of Carthage ? typical of the large-scale warfare that has made the games so popular.

But the best was yet to come: After James had played the game, provided feedback and asked questions, an artist on the team suggested they actually put James in the game. Needless to say, he accepted.

The image above shows the process of turning James's picture into a 3-D model for use in the game. What rank and position his character occupies in the game likely depends on how people play ? we reached out for more info on this from Creative Assembly, in case future players would like to see the virtual James in action when the game comes out late this year.

James died not long after his visit to the studio. Craig Laycock, Creative Assembly's community manager, said that James's enthusiasm in the face of cancer and death affected the whole team.

"His approach to life was an inspiration ? not only to me, but to the whole studio,"he wrote in a blog post. "When I say that, you have to understand what I mean. I don?t mean inspiration in the throwaway word sense. I mean a genuine inspiration ? altering my perspective permanently."
