Villages privileged after volcano erupts in Iceland

A volcano erupted circuitously a glacier in Iceland, sharpened up ash and fiery lava and forcing the depletion of hundreds from circuitously villages yesterday.

The tear at the Eyjafjallajokull volcano, located circuitously a glacier of the same name, shot ash and fiery lava in to the air but scientists called it often peaceful. It occurred only prior to midnight Saturday at a crevasse on a slant rather than at the volcanos limit so scientists pronounced there was no approaching risk that the glacier would warp and inundate the area.

TV footage showed lava issuing along the fissure, and majority flights were canceled due to the hazard of airborne volcanic ash. After an aerial survey, scientists resolved the tear struck circuitously the glacier in an area that had no ice.

This is the majority appropriate probable place for an eruption, pronounced Tumi Gudmundsson, a geologist at the University of Iceland.

Nonetheless, officials sent phone messages to 450 people in between the tillage encampment of Hvolsvollur and the fishing encampment of Vik, a little 100 miles southeast of the capital, Reykjavik, propelling them to leave immediately.

A state of puncture was spoken nonetheless there were no evident reports of injuries or damage. Evacuation centers were set up circuitously the locale of Hella, but majority people returned to their homes after yesterday. The majority evident hazard was to stock given of the antacid gases the tear released.

We had to leave all the animals behind, Eli Ragnarsdottir, a 47-year-old farmer, told RUV, Icelands inhabitant broadcaster from an depletion center. We got a call and a content summary ... and we only went.

Video: Volcano erupts in Iceland Scientists contend it is formidable to envision what comes next. Like earthquakes, it is tough to envision the expect timing of volcanic eruptions.

It could stop tomorrow, it could last for weeks or months. We cannot contend at this stage, Gudmundsson said.

The last time there was an tear circuitously the 100-square-mile Eyjafjallajokull glacier was in 1821, and that was a quiescent tear it lasted solemnly and invariably for dual years.

The ultimate tear came after thousands of small earthquakes rocked the area in the past month. Scientists in Iceland have been monitoring the volcano utilizing seismometers and tellurian positioning instruments, but Gudmundsson remarkable that the commencement of Saturdays tear was so equivocal that it primarily went undetected by the instruments.

The volcano has been inflating given the commencement of the year, both rising and swelling, pronounced Pall Einarsson, a geophysicist at the University of Icelands Institute of Earth Science. Even though we were saying increasing seismic activity, it could have been months or years prior to we saw an tear similar to this ... we couldnt contend that there was an approaching risk for the area.

Einarsson and Gudmundsson pronounced the tear could trigger a some-more deleterious tear at the circuitously Karla volcano, that lies underneath the thick Myrdalsjokull icecap and threatens large flooding and bomb blasts if it erupts.

One of the probable scenarios we"re seeking at is that this small tear could move about something bigger. This said, we cant assume on when that could happen, Einarsson said.

Exploiting the bodys own capability to quarrel a heart attack

The work has the roots in a confusing oddity that physicians have prolonged noticed in their patients: When faced with a heart attack, people who have had a prior one oftentimes transport improved than patients who have never had one. Scientists have been operative for twenty-five years to assimilate one reason because -- a routine well well well well well known as ischemic preconditioning, where a proxy limitation of red red red red red blood upsurge someway strengthens cardiac tissues down the road.

In the idealisation research, published online Feb. twenty-five in the biography Circulation Research, a organisation led by Paul Brookes, Ph.D., and connoisseur tyro Andrew Wojtovich at the University of Rochester Medical Center have grown new methods in the bid to lane down one of the key molecular agents involved. That molecule, well well well well well known as the mitochondrial ATP-sensitive potassium channel, or mKATP, is executive to ischemic preconditioning, but it has proven fugitive for scientists looking to besiege and report it.

The Rochester organisation has combined a new approach -- faster, less expensive, and simpler than stream methods -- to magnitude the wake up of mKATP. The organisation has additionally identified a molecule, well well well well well known as PIP2, that can revive the channelactivity even once it has stopped operative properly. The new work is approaching to yield new clues about how the channel, that is thought to be executive to the heart health, is regulated in the heart.

The idealisation idea of ischemic preconditioning, of course, is not to condition the heart by intentionally causing a miss of red red red red red blood upsurge to it. Rather, scientists similar to Brookes idea to have make use of of their believe to rise a new remedy or diagnosis to assistance all patients improved conflict heart repairs should it occur.

Preconditioning has been shown to be in effect in a accumulation of models in the laboratory, but it hasn"t done it to the sanatorium yet, pronounced Brookes, join forces with highbrow of Anesthesiology and of Pharmacology and Physiology. One would wish to pattern a drug to get the good of ischemic preconditioning but essentially stopping red red red red red blood upsurge in any way.

Physicians similar to cardiologist Eugene Storozynsky, M.D., Ph.D., see the materialisation of ischemic preconditioning fool around out in their patients. He says that itnot odd for a prime heart conflict studious who has had symptoms of heart disease to transport most improved than a younger chairman with no story of heart disease who unexpected has a heart attack.

The chairman with ongoing heart disease who presents with a new heart conflict does not crop up scarcely as infirm as the younger, healthier chairman with no story of heart disease, even though they benefaction to the sanatorium with scarcely matching blockages in their heart arteries, pronounced Storozynsky, a heart disaster consultant who was not concerned in the study.

Of course, the idealisation idea for patients is to forestall heart disease wherever possible, combined Storozynsky, partner highbrow of Medicine in the Cardiology Division. People need to have certain they eat a balanced, low-fat, reduced-salt diet, practice regularly, and carry out their red red red red red blood vigour -- these actions will cut down onerisk for carrying a heart conflict dramatically.

Brookes" organisation additionally detected that mKATP is indifferent by fluoxetine, whose code name is Prozac. Itthe idealisation in a list of medications that have been shown in the laboratory to block ischemic preconditioning, Brookes said. Others embody painkillers well well well well well known as cox-2 inhibitors, as well as beta-blockers that are used often to provide high red red red red red blood vigour and heart problems.

Because medications similar to anti-depressants and beta-blockers are used so at large in patients who have had heart problems, scientists should take a close see at their probable goods on ischemic preconditioning, Brookes said, observant that the drug have not been related to any cardiac difficulties in people.

The new commentary came about by a partnership of multiform investigate groups at Rochester that authorised the organisation to residence a complaint that has stubborn scientists for years. Brookes and a couple of alternative scientists had worked on mKATP, that shuttles potassium in to and out of the mitochondria, for most years, but the laboratory work concerned was so fussy that a little alternative teams have not been means to imitate the results, heading a little scientists to subject either the channel indeed exists.

Keith Nehrke, Ph.D., partner highbrow in the Nephrology Division of the Department of Medicine, due a new approach to magnitude the channelactivity. The new process involves measuring the transformation of the component thallium in to and out of mitochondria, as a broker for potassium. The new process is most faster and less costly and should be most simpler to imitate by alternative scientists, Brookes said. He and Nehrke not long ago perceived appropriation from the National Institutes of Health to have make use of of the new process in the little roundworm well well well well well known as C. elegans to brand the mKATP channel.

Then a shelter of the Department of Pharmacology and Physiology, where Wojtovich is a connoisseur student, continuous the organisation with alternative researchers who are experts on potassium channels -- Daniel A. Gray, M.D., of the Department of Medicine and Coeli Lopes, Ph.D., of the Aab Cardiovascular Research Institute.

In further to Brookes, Wojtovich, Nehrke, Gray and Lopes, authors of the paper embody former healing proprietor Marcin K. Karcz, M.D., right away with Unity Health System; and technical join forces with David M. Williams. The work was saved by the National Heart Lung and Blood Institute, the National Institute of General Medical Sciences, and the American Heart Association.

Same Brain Spots Handle Sign Language and Speaking LiveScience

Language is combined in the same areas of the brain,regardless of possibly a chairman speaks English or uses American Sign Language tocommunicate, new investigate found. The find suggests that something aboutlanguage is concept and doesnt rely on possibly people have make have make use of of of of their voices ortheir hands to talk.

Two centers in the brain Brocas area, that is thought tobe compared to debate production, and Wernickes area, that is compared withcomprehending debate have prolonged been compared with written communication. Butnow scientists have found the brain areas competence be scored equally to language, no matterwhether the oral or signed.

Scientists suspected these areas competence be sold tospeaking, since they are located spatially nearby areas that are continuous tomoving the outspoken chords, and to the heard cortex, that is used to hearsounds. In that case, it stood to reason that deaf people who have make have make use of of of of AmericanSign Language (ASL) to promulgate should have make have make use of of of of alternative brain areas to createlanguage, such as tools located nearby the visible cortex, used for seeing.

But when researchers tested twenty-nine deaf local ASL signers and64 conference local English speakers, they found no disproportion in the brain. Theyshowed both groups cinema of objects, such as a crater or a parrot, and askedthe subjects to possibly pointer or verbalise the word, whilst a PET (Positron EmissionTomography) scanner totalled changes in red blood upsurge in the brain.

In both groups, Brocas and Wernickes areas were equallyactive.����������

"Its the same possibly the denunciation is oral or signed,"said Karen Emmorey, a highbrow of debate denunciation at San Diego StateUniversity. Emmorey described the work last week at the annual assembly of theAmerican Association for the Advancement of Science in San Diego, Calif. Theresearch was additionally minute in a 2007 issue of the biography Neuroimage.

In a some-more new study, that has not nonetheless been published ina systematic journal, the scientists tested possibly pointer denunciation taps in to thesame tools of the brain as charades. They longed for to figure out possibly thebrain regards pointer denunciation as some-more identical to oral language, or some-more similarto creation pantomimegestures to impersonate an action.

The scientists showed both deaf people and conference peoplepictures of objects, such as a brush or a bottle of syrup, and asked thesubjects to "show how you would have make have make use of of of of this object." The charadegestures for pouring syrup and for unconditional with a brush are opposite �from the signs for syrup and sweep, so theresearchers could be certain the deaf participants were pantomiming and notsigning.

Then they asked the deaf subjects to pointer the verbsassociated with sold objects, such as syrup or broom. The researchersfound that the signers activated opposite tools of their smarts whenpantomiming contra when signing. Even when the pointer is basicallyindistinguishable from the mime when identical palm gestures are used the brain treats it identical to language.

"The brain doesnt have a distinction," Emmoreysaid. "The actuality that most signs are iconic doesnt shift the neural underpinningsof language."

And the scans showed that the brain areas signers used whenpantomiming were identical to the brain areas conference participants used when pantomiming both groups activated the higher parietal cortex, that is compared withgrasping, rather than brain areas continuous to language.

"It suggests the brain is orderly for language, notfor speech," Emmorey said.

Mileys `Last Song: Cyrus environment song aside

March 24, 2010, 6:34 AM EST

SANTA MONICA, Calif. (AP) -- Singing was the last thing on Miley Cyrus" mind in "The Last Song."

Other than a short sing-along to a balance on a car radio, her impression doesn"t do any crooning, something Cyrus on purpose avoided with her initial lead in a live-action movie that doesn"t underline low-pitched alter-ego Hannah Montana.

"I didn"t instruct to sing in the film. We sang in the car that once, but that doesn"t unequivocally count. I didn"t instruct to do a opening thing," pronounced Cyrus, who additionally contributes dual songs to the soundtrack but total she wants to keep singing and behaving apart from right afar on.

"I never contend I"m not going to do anything. Then if I finish up you do it, I"m going to get a lot of crap. `She pronounced she"d never ...", you know? And I don"t have time for that play and people freaking out. But majority likely, I"d similar to to stay afar from song in drive-in theatre and do a small something less obvious."

Music in ubiquitous is going on hold for Cyrus, who pronounced an arriving manuscript will be her last for at slightest a couple of years, since she wants to combine on big-screen roles.

Cyrus, 17, has a handful of episodes left to fire in the last deteriorate of "Hannah Montana," the Disney Channel array that done her a star. She has remained in the Disney fast for a "Hannah Montana" unison movie and underline movie and led the voice expel with John Travolta in the studio"s charcterised strike "Bolt."

"The Last Song," additionally from Disney, is a distributed bid by teenager statue Cyrus to connoisseur in to some-more grown-up domain and move her fans along but alienating them as she moves over Hannah"s happy world.

Cyrus" mother, Tish Cyrus, was the senior manager writer on "The Last Song."

"She and Tish, her mother and additionally her manager, are unequivocally shrewd people and knew precisely what would be the right subsequent movie for Miley," pronounced Julie Anne Robinson, who destined "The Last Song." "She"s demonstrated that she has got romantic range and abyss in this movie that can take her forward. I unequivocally think she could do roughly anything."

Cyrus" character, Ronnie, is traffic with grave issues involving her divorced relatives (Greg Kinnear and Kelly Preston) as she reluctantly spends a summer with her disloyal dad, a composer and pianist who would love zero some-more than to see his daughter resume her own deserted piano studies.

Yet "The Last Song" additionally lets Ronnie put in a little fun time at the beach with a hunky new lover (Liam Hemsworth, Cyrus" real-life boyfriend).

"It"s a great steppingstone. Nothing as well crazy. It"s mature, but it"s kind of for everyone," Cyrus said. "I think my subsequent step, I"ll get some-more and some-more grown up and edgier, but I think it was the most appropriate steppingstone for me."

"The Last Song" was created privately for Cyrus by writer Nicholas Sparks, whose best-selling love stories embody Hollywood adaptations such as "The Notebook," "A Walk to Remember," "Nights in Rodanthe" and this year"s "Dear John."

Cyrus had voiced seductiveness in receiving on an inspirational story similar to "A Walk to Remember," and Sparks grown the tract and characters, afterwards worked up the screenplay with his crony Jeff Van Wie. Once the book was done, Sparks sat down to write the novel version of "The Last Song," that came out last year.

Sparks tailored tract points to Cyrus, vouchsafing her select her character"s name (Ronnie was her grandfather"s name) and building sequences in that Ronnie tries to save a nest of involved sea turtles after Cyrus referred to she desired animals.

"The Last Song" turns melancholy, and Ronnie is forced to understanding with profanation and tragedy even as she reconnects with her father.

"This was not an easy purpose for Miley. This was not an easy purpose for any actress," Sparks said. "This was as tough as what Rachel McAdams did in `The Notebook" or what Diane Lane did in `Nights in Rodanthe." Those were grown up women who did those roles. She"s seventeen years old. It was not easy for her, and I thought she did a unusual job."

Cyrus pronounced she has had an peculiar personal tour with the purpose that done her famous, Hannah, the pop-music luminary vital a stand in hold up as an typical schoolgirl.

"It"s kind of a uncanny cycle. I didn"t unequivocally describe to her since I didn"t know the important life. Then I accepted it, and I associated to her. And now, I don"t unequivocally describe to her anymore, since I"ve gotten some-more grown up than that, and the show can usually go so far for the channel it"s on."

With the show impending the end, Cyrus pronounced she doubts she would revive Hannah for an additional big-screen movie.

"I think once the wig"s off, it"s off," Cyrus said. "I get vagrant fans. I think it"s honeyed that they"re regularly understanding of the show, but my instruct is they"ll await me whatever I do, and that"s what a loyal fan is. Whatever I"m doing, if the art that I"m creation is creation me happy, afterwards apply oneself my qualification and apply oneself the art that I"m making."

Apple COO gets $22 million prerogative as Jobs substitute

Gabriel Madway SAN FRANCISCO Fri Mar 12, 2010 6:25pm EST Related News UPDATE 2-Apple COO gets $22 mln reward as Jobs stand-inFri, Mar 12 2010

SAN FRANCISCO (Reuters) - Apple Inc has awarded its chief operating officer a bonus valued at $22 million for leading the company while Chief Executive Steve Jobs was on 6-months" medical leave last year.

Technology&&&&Asian Markets&&&&Media

The cash-and-stock award came at Jobs" recommendation, and was made in recognition of Tim Cook"s "outstanding performance in assuming the day-to-day operations" at Apple while Jobs was out, the company said in a filing on Friday with the U.S. Securities and Exchange Commission.

Many analysts and investors believe Cook could one day succeed Jobs as CEO at Apple, although the company has never disclosed any succession plan.

Cook received a $5 million bonus plus restricted stock award worth roughly $17 million, based on Apple"s closing share price of $226.60 Friday. Half of the stock is scheduled to vest on March 10, 2011, and the other half on March 10, 2012, as long as Cook stays with Apple through those dates.

"The bonus is a reward and is also to stay competitive," said Kaufman Bros analyst Shaw Wu.

"Cook has been targeted by other companies, and he"s proven to be very adept and capable at leading Apple. I think they need to keep the conversation competitive to keep him from getting lured away," he said.

An Apple spokesman declined to comment beyond the regulatory filing.

Jobs stepped away from his duties in January 2009 for health reasons, although he remained involved in major strategic decisions. Cook took over day-to-day operations.

Jobs, a pancreatic cancer survivor, underwent a liver transplant while on leave, returning to the company in late June.

While Jobs was on leave, Apple"s shares surged roughly 70 percent.

Cook was named COO in 2005. He is responsible for managing Apple"s supply chain, sales, service and support. He also leads the company"s Mac computer division.

He joined Apple in 1998 as senior vice president of operations. Prior to that he held executive positions at Compaq and International Business Machines Corp.

According to Apple"s proxy statement, Cook received total compensation of roughly $14 million in 2009.

Shares of Cupertino, California-based Apple closed up 0.5 percent at $226.60 on Nasdaq.

My husbands a amatory Dad and a dab palm at ironing - and each day he goes to work I know he could be blown to pieces

Worried wife: Rebecca Stevens lives in fear of her husband being killed in Afghanistan

Worried wife: Rebecca Stevens lives in fear of her husband being killed in Afghanistan

Rebecca Stevens has meticulously planned every single detail of her husband"s funeral. She knows the hymns he would like, the pall bearers he would choose to carry his coffin into the church and exactly where he will be buried.

Sadly, she also knows in stark detail the emotions that will flood through her on the day. She has seen too many other widows make the lonely walk behind their husband"s coffins to remain in ignorance.

Rebecca"s husband, Warrant Officer John Stevens, doesn"t have a terminal illness. Instead he plays the grisliest form of Russian roulette with his life as a bomb disposal expert in Afghanistan.

And as a solicitor specialising in family law, Rebecca is definitely no fool.

"I am an extremely positive person - we both are," says the 32-year-old mother of Josh, nine, and William, four.

"But when your husband is on the front line, as John is, you can"t bury your head in the sand.

"Before he left for his first tour of duty in Afghanistan, John sat me down and suggested sorting out his funeral arrangements. To an outsider I know it must sound utterly macabre. But John was simply being pragmatic.

"I know he"ll do all he can to stay safe and come home to me and his sons. But when your husband has one of the most dangerous jobs in the world, you have to face the very real chance that the next time I see him might be in his coffin."

John, 40, is one of the Army"s elite band of bomb disposal experts. A tightly knit brotherhood, they have been rocked by five deaths in Afghanistan alone. As the war intensifies, they deal with at least five bombs every single day and are considered high value targets by the Taliban.

The death toll of soldiers in Afghanistan recently reached 263 - more than the number who perished in the Falklands War.

More...Meet Treo, the hero army dog who took on the TalibanTears for a hero: Tough soldiers weep for Prince Harry"s "legend" friend killed in AfghanistanWomen set to serve in submarines as Britain follows U.S. Navy ruling

The most dangerous job of all belongs to the bomb disposal experts. Two have been blown up on duty in the past few months. As we meet at their home outside Bath, surrounded by toys and school photos, the dangers seem a nightmare happening on another planet.

For this very ordinary family, the dangers posed by the Taliban are horrifically real. On the day we meet, John"s comrade, Captain Daniel Read, is being buried.

The 31-year-old died while trying to disarm an explosive device laid by the Taliban. He had just returned to Helmand Province after two months recovering in Britain from injuries suffered in an earlier blast.

But he had begged to return early to replace Staff Sergeant Olaf Schmid, who died last October in his final mission before returning home. John is waiting for a date to return to Afghanistan.

So what makes a man choose to put his life on the line every working day? And how do his family survive the nail-biting wait to know if he will be coming home?

"John doesn"t tell me everything - it"s too shocking," says Rebecca. "But some of the things have left my hair standing on end. Sometimes I look at my husband - a loving father, a great cook and a dab hand with the iron - and can"t believe that he lives his life on a knife edge."

Rebecca was 20 when she met John at her sister"s wedding in 1998. She was the bridesmaid, he was a friend of the groom and it was full-blown passion at first sight.

"In his speech, my dad joked that he"d got another daughter - me - who he"d like taken off his hands," she laughs. "John was sitting next to me and I remember teasing him: "You"re the man I"m going to marry." And I meant it. He was gorgeous - and a fantastic listener with this amazing inner calm and self-assurance. We talked and talked."

John joined the Army 18 years ago after taking a two-year engineering course. He was then hand-picked for the elite Explosive Ordnance Disposal Regiment.

At the end of the wedding, they swapped phone numbers. But, as the days ticked by and John failed to ring, Rebecca became increasingly anxious. Finally she rang a mutual friend, pretending that she"d left her purse in John"s car and needed to get in touch.

But John had lost her number. And he"d rung the same friend with an almost identical ruse - that he"d left a tie pin with Rebecca.

"We started dating and three months later I got my first taste of Army life," says Rebecca. "John was posted to Canada. We wrote, but I missed him like mad.

Although John had told me that he was with the Royal Logistics Corps, I still didn"t really understand his job. People imagine that guys who risk their lives are gung-ho action heroes, racing around the world and boasting about their exploits.

"John is the antithesis of that. He is extremely gentle, modest and unassuming - it"s one of the things I love about him. When we first started dating my grandfather was quite poorly. At family functions, John would always ensure he was the one who wasn"t drinking, so he could take Grandad home.

"I guess the only clues are that he is incredibly meticulous. When he irons my blouses, there isn"t a wrinkle in them and he even irons creases in jeans.

"So, even when we married in 1999, I didn"t fully appreciate what he did - or rather the danger he was in. I remember asking him: "So what exactly do you do every day?" and John just said: "Oh, it"s mostly paperwork."

"When I pinned him down, he explained that he kept people safe. That"s honestly how he sees his work. He believes passionately in saving lives and is prepared to put his own life in danger. And all without any big show.

"So I didn"t worry about the risks because he made light of them. It"s the way he is. Besides, when we first married, no one could have predicted the deadly threat of terrorists in Iraq and Afghanistan

"I realised John would be away a lot and I wanted my own life and career. So I started a law degree at Oxford Brookes University."

WHO KNEW?There are 17,900 service women in the British military only four of whom are bomb disposal experts

But the reality of John"s job was hammered home within a few months. After being specially trained to deal with highly sophisticated explosives in a warzone, John was posted to Northern Ireland.

Rebecca was seven months pregnant with their first son when, idly scanning the newspaper one morning, she found herself looking at John"s face.

"He was on the front page of the paper, wearing goggles, dealing with the aftermath of an explosion. I sat there rigid with shock," she says. "It"s one thing knowing what your husband does for a living; it"s quite another seeing the reality. John still said very little about his job - he didn"t want to worry me and he knew he had to be extremely cautious on phone lines because his work was so sensitive.

"But I knew I couldn"t bury my head in the sand any more. It wasn"t fair on him. If I didn"t try to share John"s world, we would drift apart. I told John I needed to know everything.

"It was a relief for both of us. Now, after every tour of duty in a warzone, John comes home and we have a debrief, though there are things I"d much rather I didn"t know because it leaves me scared."

Their first baby, Josh, was born in 2000. And Rebecca rapidly found herself struggling with the reality of being an Army wife while trying to pursue her studies. John saw their baby for just eight weeks during his first year.

Based in Didcot, Oxfordshire, far from family and friends, it was tough. But then tragedy hit the family. The couple"s second son, Matthew, was born in 2001. He failed to thrive and, when he was three months old, he was diagnosed with the very rare Pompe Disease, an inherited metabolic disorder.

Tests showed that Matthew"s heart was fatally enlarged. Doctors explained that he would live less than a year. In fact, he died in Rebecca"s arms, on January 2002, a week after leaving hospital. He was just four months old.

"John is incredibly tough - he must be to do his job," says Rebecca. "But, when Matthew died, we both wept and wept. I loved John all the more because he was never afraid of showing his emotions. As he held our son for the last time, he was so tender.

"John"s seen innumerable dead bodies, but losing our son touched him like nothing else."

John had been due to go to the Middle East. But when their baby died, the Army gave him a training job which meant he could go home every evening. Although the couple were told they faced a one-in-four chance of having another baby with Pompe Disease, they decided to take the risk. William was born in May 2005.

However, although clear of the disease, he weighed just 3lb 13oz and was very sickly.

"We are extremely upbeat people - it"s the only way we"ve survived John"s job - but we were on tenterhooks until William was born," Rebecca admits. "His first few months were a nightmare. He couldn"t eat properly so, when he was one year old, he had a gastric tube fitted."

Thankfully, William"s situation has stabilised and he is able to eat normally now. But to add to her terrible stress, in 2008 John was posted to Afghanistan. "As the day got nearer, I became increasingly frightened," she admits. "I had so much on my plate - the boys, my law training. But everything paled into insignificance."

Those six months were the longest of her life. But as John now faces a second tour of duty in Afghanistan, Rebecca is well aware that this time will be even harder.

"I try and tell myself that he"s always come back safe before and he will do again," she says. "But the job is becoming increasingly dangerous. We know so many of his colleagues who have been killed out there. And each death makes it more frightening for the other families.

"Luckily, William is too young to understand, but Josh sees the news and is well aware that his dad is in danger.

"When I told him that Daddy would be going away soon, he became terribly sombre. First of all he reassured me that he would make sure his little brother kept his room tidy.

"Then he wanted to know: "Will Daddy be all right?" I explained that Daddy had always come back safe and this time will be no different. It"s what I cling to, but I"m scared. I work with women who have husbands with ordinary jobs and ordinary lives, and I realise just how abnormal my life is.

"They"re extremely supportive, but I feel very isolated and frightened. I will get to talk to John only twice a week for ten minutes each time. I know he won"t want to tell me all that he has been through and I will be sure not to trouble him with my worries. Effectively, my life is on hold until he comes home safe.

"Every time my mobile rings I"ll wonder if it"s the phone call I dread telling me that John has been killed or - almost worse - badly injured. When I drive home from work, I know I"ll be panicking in case there"s a car outside my drive.

"Do they tell you bad news in front of your children or do they wait until the kids are safe in bed? I just don"t know. I"m determined not to cry in front of the boys if the worst happens, but that doesn"t mean I won"t be petrified inside.

"When he goes to Afghanistan, John will take a photo of us all and my wedding garter.

"They are little talismans to keep him safe. I tell myself that loving us and having us to come home to is the best guarantee of his safety I can ask for."
