'Cool!': Former Marine exclaims with joy in video showing his incredible progress just 4 months after receiving double arm transplant

It is just four months since former Marine sergeant John Peck received a double arm transplant.  But he is already showing incredible progress.  Peck lost all four limbs after standing on a homemade bomb in Afghanistan in 2010. Now, the 31-year-old has reached a milestone he never thought possible: he has two fully functioning arms - and is gaining control of his right elbow. In a video posted to his Facebook page on Tuesday, Peck shared a short exercise with his physiotherapist, sliding a block forwards and backwards across a table. For most, it would be simple. For John, it marks a moment of triumph. He beams at the camera as his physiotherapist straps the wheeled block onto his arm. Viewers then watch as Peck visibly strains to push it away from him, and back to his chest, over and over again. Finally, after reaching his total, he says, 'cool!'

Woman, 23, is accused of being DRUNK by strangers after a deadly mass on her brain left

Zoe Roscoe, (left) 23, from Bolton, was diagnosed with a brain AVM - a tangle of abnormal blood vessels which can bleed and expand - in 2013. It caused her to suffer stroke-like symptoms, and after a scan, she was told the mass on her brain was a 'ticking time bomb' (inset).

Grandmother who went to hospital with broken arm died from pneumonia and sepsis

Patricia Fowler, 75, was not assigned to a doctor at Blackpool Victoria Hospital, Lancashire, because she was overlooked by a secretary who mistook her for another patient, an inquest heard. There was confusion over who was caring for Mrs Fowler and she was left to grow increasingly ill on a cardiac ward, even after her son raised concerns over her health. Mrs Fowler was eventually seen by doctors three days after being transferred to the ward but by that point had developed pneumonia and sepsis, which led to her death.

Schoolboy has jaw built using his LEG BONES after tumour ravaged his face

Adam McCalmont (right), 16, from Coleraine, Northern Ireland, was diagnosed with mesenchymal chondrosarcoma - a rare form of bone cancer - after complaining of a dull ache in his jaw. Doctors warned there was a chance operating on the tumour could permanently paralyse the schoolboy, or even kill him. Thankfully, chemotherapy proved to be successful and worked in shrinking the tumour. This allowed him to finally undergo a 19-and-a-half hour operation (left) to replace the ravaged muscles and arteries in his face with ones from his leg. He is still struggling to move the left side of his face, but doctors have high hopes for his recovery.

The gold curls create a cheerful first impression but dissolved into a film that clung to my lips, leaving a strange synthetic flavour. I tried a classic hot chocolate afterwards and it tasted bitter compared with this sugary (but heart-warming) slurry.

California mother of conjoined twins says 'it's a dream come true'

It was one of the riskiest separation surgeries ever performed. But the 50-surgeon team that divided two-year-olds Eva and Erika Sandoval today appeared at a press conference beaming. The Californian girls shared a digestive system, a uterus, a liver, a bladder, a pelvis, and a third leg with a seven-toed foot. Just two days after the grueling 18-hour operation, the girls are still being closely monitored in the intensive care unit. However, lead surgeon Dr Gary Hartman gushed that both are doing far better than expected. Most excitingly, Erika - the smaller twin who was getting smaller, weaker, and more sickly ahead of surgery - is seeing the most significant improvements. The team has also released photos from inside the operation, and pictures of the 3D-printed models of the girls' shared body parts. Weeping at the press conference with their father Arturo, mother Aida said: 'It's been a dream come true.'
