4 . When Kurt Benirschke started collecting skin samples from endangered animals in 1972, he didn’t have a firm plan on what to do with them. As a researcher at the University of California San Diego, he believed that one day these samples would be used to save these animals. A few years later, he moved his collection to the San Diego Zoo, and called it the Frozen Zoo.
For a long time, it was the only project of its kind; however, in recent years, similar conservation efforts have spread globally, and tools that Benirschke didn’t yet have are now available. Today, the Frozen Zoo is the world’s largest animal cryobank(生物冷冻库), holding samples from over 10,500 individual animals from 1,220 species, in the hope that one day science can bring them back as a species.
The Frozen Zoo’s advanced technology is the key to its success in saving species from extinction. By using cryopreservation techniques, the zoo can store cells and tissues from endangered animals. The stored genetic material can be used for research, breeding(繁殖) programs, and potentially even cloning or genetic engineering to restore endangered species.
By protecting the genetic heritage of endangered animals, the Frozen Zoo provides hope for the survival of species that would otherwise be at risk of dying out, and the preservation of Earth’s precious biodiversity. It has inspired the establishment of similar cryobanks worldwide, expanding efforts to conserve endangered species. These cryobanks contribute to the global network of genetic resources, improving cooperation and knowledge exchange. By demonstrating the potential of technology in the preservation of biodiversity, the frozen zoo serves as a powerful tool in raising awareness and driving change.
The Frozen Zoo is like a time capsule, preserving the genetic heritage of endangered species for future generations. It reminds us about the importance of conservation and offers a window into a world that could otherwise be lost forever.

6 . Vehicles on our roads are now mostly petrol and diesel (柴油) cars, but their days cannot continue for much longer. A recent university study found that current electric cars could be used for 87 percent of daily car journeys in the US. That figure could rise to 98 percent by 2020.
One hurdle to the widespread adoption of electric cars has been “range anxiety” — drivers concerns about running out of electricity on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. That said, charging points are becoming increasingly common throughout the USA.
Attitudes towards electric vehicles have changed greatly over the last few years. Not that long ago, electric cars were met with distrust, and their high prices drove customers away. Thanks to improvements in battery capacity, recharging times, performance and price, the current generation of electric cars are starting to persuade picky consumers. Plug-in cars will soon give internal combustion engine (内燃机) models a run for their money.
As well as development on the road, electric vehicles are taking to the seas and skies. Electric boats are among the oldest methods of electric travel, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric air travel are also being made, with Airbus and NASA among the organizations developing and testing battery-powered planes. The experiments could soon make commercial electric flight a reality.
Electric vehicles do not produce any emissions (排放). If the US could replace 87 percent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 percent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim (声称) to be completely emission-free. That said, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.
