澳大利亚上千只考拉死亡 | 一周看点
But hundreds others of already vulnerable koalas are feared dead in a historic bush fire that has torn through the eastern Australia coast. That fire has claimed the lives of at least four people.
Rescuers and volunteers wandering through charred eucalyptus trees in New South Wales for marsupial survivors have found bleak signs of devastation: koalas incinerated while seeking refuge, leaving ash where conservationists hoped to tally the dead.
“It’s a national tragedy,” Port Macquarie Koala Hospital Clinical Director Cheyne Flanagan told ABC News Australia.
She estimated earlier this week that as many as 350 koalas had been killed and said that number could certainly rise as koalas dehydrate or starve to death. More than 2.5 million acres have already burned on the east coast, with more fires in the west.
Fire roared through serene Lake Innes Nature Reserve, where as many as 600 koalas lived in a colony and died in the trees while seeking shelter, News.com.au reported.
The medical team from Detroit's Henry Ford Hospital said the patient, a 17-year-old male, underwent the roughly six-hour transplant surgery October 15.
He spent a month on a life-support machine after suffering “complete lung failure” and would have faced “certain death” without the operation, according to the doctors.
The teen’s family described him as an athlete who was in perfect health before he was admitted to the hospital in early September with what appeared to be pneumonia. Within weeks, his condition had become so dire that he shot to the top of a national transplant list, where most patients spend months waiting for a donor.
“What I saw in his lungs was nothing that I’ve ever seen before, and I’ve been doing lung transplants for 20 years,” Hassan Nemeh, the hospital’s surgical director of thoracic organ transplant, said at a Tuesday news conference.
“There was an enormous amount of inflammation and scarring in addition to multiple spots of dead tissue. And the lung itself was so firm and scarred, literally we had to deliver it out of the chest,” he said. “This is an evil that I haven’t faced before.”
As we try to find the answer to climate change, each eco-innovation may spur even more questions about their overall effects.
Could the noise from wind turbines cause cancer? (Science says no.)
Could the sound from an electric car stimulate plant growth, regenerating the environment we’ve helped destroy? Science says . . . maybe? Or at least, that’s the hope of Ayax Toyota.
Within the next two years, the U.S. and Europe will require electric cars to emit a noise in order to warn pedestrians of their approach, or else these quiet vehicles can take pedestrians and bikers by surprise.
In 2018, Saudi Aramco made $111 billion dollars in profit. The second-most profitable company, Apple, made $60 billion that year.
On November 3, Aramco officially announced its plan to go public for the first time in the company’s 86-year history. And on November 17, the oil giant announced the company could be valued at $1.7 trillion. Energy historian Ellen R. Wald joined Today, Explained to explain why Aramco’s initial public offering (IPO) is such a big deal.
11月3日，成立86年的阿美公司首次正式宣布上市计划。11月17日这家石油巨头公司宣布估值为1.7万亿美元。能源历史学家Ellen R. Wald作客播客《Today, Explained》解释了为什么阿美公司上市如此重要。
As the most profitable company in the entire world, she says, the company’s IPO is going to set major records. And since it’s the largest oil company in the world, it’s likely that a lot of everyday things we use - from plastic to the energy fueling our cars - touches this company.
