The first successfully cloned endangered animal 第一只被成功克隆的瀕危動(dòng)物

This black-footed ferret(雪貂)is not only cute,she is beyond special.Meet Elizabeth Ann,the first endangered animal to be successfully cloned in North America.

In a joint scientific effort between the US Fish and Wildlife Service,and a combination of other organizations,an endangered species was successfully cloned.This is a huge deal on so many levels,especially for the future of species biodiversity.

Back in 2013,an organization called Revive & Restore popped up on the radar of the US Fish and Wildlife Service.Their goal is to“involve bio-technologies in standard conservation practice”.There's no denying that biodiversity hasgreat importance in conservation efforts when there are a few living animals of a species left.

Before that,way back in 1985,genetic samples from Willa,a wild black-footed ferret,were shipped to a geneticist at the San Diego Zoo.These genetic samples led to the ferret alive today.Dr Ryder,the aforementioned geneticist,works at a place called the Frozen Zoo.This incredible place houses the “l(fā)argest and most diverse collection of its kind in the world”.This frozen library of life contains over 10,000 living genetic samples.The combined achievement to successfully clone the endangered blackfooted ferret is big news for this organization.

Elizabeth Ann's journey towards life began when all of the above organizations teamed up with ViaGen Pets & Equine,a commercial cloning company.A domesticated ferret was used to implant the created embryos,which was successful.Then on December 10,Elizabeth Ann was born via C-section (剖宮產(chǎn)).She was cared for,and once she was stable,tests were done to confirm her genetic makeup.

Other clones from Willa's samples will join Elizabeth Ann at her current home at the National Black-footed Ferret Conservation Center in Colorado.This exciting experiment will continue as scientists work towards understanding the effects that these clones will have on the larger ecosystem,and if they will ever be able to be integrated into the wild population.

These developments are beyond exciting for the protection of many lost and endangered species.All eyes are on the Frozen Zoo and the future of cloning to protect and revitalize(使……恢復(fù)生機(jī))threatened species around the world.

The rise of online learning 線上學(xué)習(xí)成熱潮

Globally,over 1.2 billion children are out of the classroom because of COVID-19.As a result,education has changed dramatically with the unique rise of E-learning.Research suggests that online learning has been shown to increase the reserve of information,and take less time.

While some believe that the unplanned and rapid move to online learning—with no training,insufficient bandwidth (帶寬),and little preparation,will result in a poor user experience,others believe that a new mixed model of education will arise with significant benefits.

There is evidence that learning online can be more effective in a number of ways.Some research shows that on average,students remember 25%-60% more material when learning online compared to only 8%-10% in a classroom.This is mostly due to the students being able to learn faster online;E-learning requires 40%-60% less time to learn than in a traditional classroom setting because students can learn at their own pace,going back and re-reading,skipping,or accelerating through concepts as they choose.

There are,however,challenges to overcome.Some students without reliable Internet access or technology struggle to participate in digital learning;this gap is seen across countries and between income levels within countries.For example,while 95% of students in Switzerland,Norway,and Austria have a computer to use for their schoolwork,only 34% in Indonesia do,according to OECD data.

For those who do have access to the right technology,the effectiveness of online learning varies amongst age groups.The general consensus (普遍共識(shí))on children,especially younger ones,is that a structured environment is required,because kids are more easily distracted.To get the full benefit of online learning,there needs to be a combined effort to provide this structure and go beyond copying a physical class/lecture through video capabilities,instead,using a range of cooperation tools and engagement methods that promote “inclusion,personalization and intelligence”,according to Dowson Tong,Senior Executive Vice President of Tencent and President of its Cloud and Smart Industries Group.
