Surgery

The team at Sun Yat-sen University used a technique called base editing to correct a single error out of the three billion "letters" of our genetic code.

They altered lab-made embryos to remove the disease beta-thalassemia. The embryos were not implanted.

The team says the approach may one day treat a range of inherited diseases.

Zac Mitchell, 20, was injured in April while working on a remote farming property in Western Australia.

"A bull kicked my hand into the fence," Mr Mitchell said of the incident.

He underwent two unsuccessful operations to reattach his thumb before doctors opted to relocate his big toe in surgery lasting eight hours.

Mr Mitchell said fellow workers had attempted to preserve his thumb immediately after the accident.

"They put it in the esky [cooler] with some ice," he told the BBC.

"She is very happy, she started dancing in her bed," Dr. Muffazal Lakdawala told CNN. "Her smile has come back."

Before she traveled to India for her operation, Eman weighed 1,102 pounds (500 kg) and she'd barely left her bedroom in more than two decades, her family said.

Over the last couple of years she'd been confined to her bed after a stroke severely impaired her speech and mobility.

In my career as a mobility coach in professional sports, I've helped numerous athletes rehabilitate from sports hernia surgeries, so I was familiar with the recovery process and had set my expectations accordingly.

However, during my surgery prep and procedure, the doctor discovered that the damage to my core was considerably more than just a hernia.

Pulei Latu, 19, underwent radical surgery on Friday to remove the rapidly-growing benign tumour near her cheek – which was affecting her speech and had already deformed parts of her mouth and teeth.

‘Sometimes I look in the mirror, and yeah, I think it’s grown bigger,’ Ms Latu told 7 News before the surgery.

‘It’ll be good because they change mine (sic) to my normal face.’

The teenager’s life-changing surgery was sponsored by Children First Foundation, an organisation that helps children in serious medical need from developing countries.

Doctors operated on a bullet lodged in 26-year-old Jorah Shane's spine. The man who shot her killed her father, Jason, and mother, Tana, on Wednesday after they stopped to help him and he told them he ran out of gas, according to Ada Shane, Jason's sister.

Police in Wyoming arrested Jesus Deniz Mendoza, 18, about 120 miles away from the shooting. FBI agents arrived Thursday to start proceedings to bring him back to Montana to face charges, the Park County Sheriff's Office said.
