1 . Finnish researchers say they have produced coffee in a laboratory that smells and tastes very similar to the real thing. The team reports that lab-grown coffee could be important as climate change continues to threaten traditional coffee farming.
Scientists at Finland’s VTT Technical Research Center created cell cultures (培养物) from the leaves of coffee plants. The process involves floating the cell cultures in bioreactors (生物反应器) filled with nutrients. The same method is used to make other kinds of animal- and plant-based products.
Heikki Aisala is a VTT researcher who oversaw the process. Aisala said that cups of the cellular (细胞的) coffee probably would not pass taste tests comparing it to traditional coffee. “Not like, of course, 100 percent. It tastes like a combination of different types of coffees,” Aisala said. The researcher added that while the cellular coffee is not ready for the market just yet, “it certainly does resemble coffee at the moment.” Aisala added it is possible that the lab-grown version could one day develop into a multi-billion-dollar industry.
VTT Research team leader Heiko Rischer said cell cultures offer a more sustainable way to make coffee. This is because coffee is in high demand. This has led to countries opening up more land to grow coffee beans, which causes increased deforestation (滥伐森林). Rischer said the environmental benefits of lab-grown coffee include reduced use of pesticides(农药) and fertilizer and less need to ship coffee beans long distances to markets.
In Europe, lab-grown coffee would need to be approved before it could be marketed. But an important question remains: Will coffee lovers actually drink the lab-grown creation? A Reuters reporter put that question to Satu, a server in a Helsinki coffee shop.
“I think someday we’re going that way because all the natural coffee sources are disappearing,” she said. “So, we have to move along... if it tastes good and the aroma (香味) is coffee based, so why not? I think it’s possible.”

10 . What’s next after the smartphone?
Humans can perform tricks today that magicians couldn’t have imagined 50 years ago. Armed with only a tiny device today, our smartphone allows us to access a lifetime’s worth of information, connect with anyone in real time even if they are miles away and perform complex tasks like drawing a floor plan within minutes. But, the most astonishing part of this technological “magic” is the speed at which new opportunities and experiences are coming out.
From generation to generation, we have seen the inevitable connection between humans and technology as advancements are adopted to serve us and improve our quality of life. And the rate of technological progress is doubling every year.
Twenty years ago, who would have thought that we would be walking with robots and cyborgs (半人半机器的生物)? With the advancement of technology, we humans are accepting digital technologies to improve and extend our senses and capabilities.
Take Moon Ribs and Neil Harbison for example. They are the founders of the Cyborg Foundation, which aims to help humans become cyborgs, defend cyborg rights and promote cyborgs as social and artistic movement. Both Ribs and Harbison are cyborgs, with Ribs having a seismic chip put into her arm so she can feel earthquakes all around the world in real time and Harbison, who is color blind, has an antenna (天线) put into his head to allow him to be aware of visible and invisible colors via sound waves.
This is only the beginning of beginnings. As we continue to spend more time with machines, the more they will become embedded (嵌入) in our lives. Technology already feels like it has a mind of its own, and over the next two decades, this will become even more pronounced.
Machines will eventually become as intelligent as us, and, while today they may just live in our pockets, tomorrow they could be in our blood stream and our minds, linking us to the cloud. And as this gap separating humans and machines continues to close, we will reach a point where we become indistinguishable from one another. Technology and humanity will fuse (融合) together some day in the near future.
