2 . To produce the classic clothing, blue jeans, producers rely on indigo dye (靛蓝染料), the only molecule known to provide jeans’ unique, beloved color. While indigo itself naturally comes from a plant, growing demand for blue jeans throughout the 20th century gave rise to synthetic (合成的) indigo, which is now more commonly used.

Indigo is the dye that makes jeans blue, but it doesn’t mix with water. To dye clothes, usually, chemicals are needed to make the color stick to the cloth. But in Denmark, scientists have created a new way to dye clothes using an enzyme (酶), which is a kind of protein that can cause chemical reactions, instead of harmful chemicals. This new method is better for the environment and doesn’t use poisonous stuff.

The chemical process for dyeing blue jeans has persisted for the last century. Workers are exposed to the poisonous chemicals, which also pollute the environment near factories. Waste water from those factories often ends up in waterways, decimating local ecosystems and even dyeing rivers blue.

Ditte Hededam Welner, the study’s lead researcher, says their new enzyme works really well and is strong enough for making lots of jeans without breaking down. This enzyme makes dyeing with indican, which is like indigo, much less harmful to the planet — about 92% better than the old way.

However, the new method doesn’t fix all the environmental problems of making jeans. Making a single pair of jeans uses a lot of water — enough to fill many bathtubs — from growing the cotton to putting the final touches on the jeans.

Even though the new dyeing process is better for the environment, it’s not always easy or cheap to change to it. Welner’s team isn’t sure if jeans companies will find it easy or affordable to switch to this method. It costs a little bit more — just seven cents extra per pair of jeans — to use the enzyme for dyeing. But Welner believes it’s worth it because it’s much better for the environment.

4 . We cannot argue with reality. We cannot argue with science. Therefore, we simply cannot argue with the fact that there are no straight lines in the universe.

Let’s start with science. The science of a straight line falls under the subject of physics. It might seem like a complicated topic, but the theory behind it is pretty simple. If you start rowing in a boat from one place and keep sailing, the concept of the curved (弯曲的) Earth will take you in a circle and you will end up where you started. The brain forms the concept of a straight line to simplify what you see in nature. Consider it a tool for the mind to recognize reality.

The concept of straight lines was controversial and heavily influenced the politics and society of Europe from the 15th century to the 17th century. Greek thinkers and scholars like Aristotle in the 5th century already proved that the Earth was a globe, but many Europeans at that time did not believe in this idea! However, some Europeans during the Age of Exploration denied this belief. Just as the famous Italian scientist Galileo Galilei was persecuted (迫害) for advocating a heliocentric (日心的) model of the solar system, many thinkers like Giordano Bruno were shamed for believing that the Earth was round.

Well, my friends, let’s move on to life. The concept of nothing going in a straight line can be associated with life as much as it relates to science and architecture. Whenever you do something, it never turns out to play out exactly as planned. I especially know that as a thirteen-year-old! Life is a rough road—every time you go forward, it is followed by two steps back or to the side. Just like how science explains it, life is a curvy path full of unexpected twists, turns, and adventures that nobody can ever predict.

5 . With a brain the size of a pinhead, insects perform fantastic navigational (导航的) abilities. They avoid obstacles and move through small openings. How do they do this, with their limited brain power? Understanding the inner workings of an insect’s brain can help us in our search towards energy-efficient computing, physicist Elisabetta Chicca of the University of Groningen demonstrates with her most recent result: A robot that acts like an insect.

In search of the neural (神经的) mechanism that drives insect behaviour, PhD student Thorben Schoepe developed a model of its neuronal activity and a small robot that uses this model to navigate. Schoepe’s model is based on one main principle: always steer towards the area with the least apparent motion.

He had his robot drive through a long “corridor”— consisting of two walls with a random print on it—and the robot centred in the middle of the corridor, as insects tend to do. In other virtual environments, such as a space with obstacles or small openings, Schoepe’s model also showed similar behaviour to insects.

“The model is so good,” Chicca concludes, “that once you set it up, it will perform in all kinds of environments. That’s the beauty of this result.”

The fact that a robot can navigate in a realistic environment is not new. Rather, the model gives insight into how insects do the job, and how they manage to do things so efficiently.

Chicca explains, “Much of robotics is not concerned with efficiency. We humans tend to learn new tasks as we grow up and within robotics. This is reflected in the current trend of machine learning. But insects are able to fly immediately from birth. An efficient way of doing that is hardwired in their brains. In a similar way, you could make computers more efficient.”

7 . Many people consider mosquito bites just part of summer living but these insects can carry diseases. Mosquitoes are actually some of the most dangerous creatures on the planet. According to the World Health Organization, mosquitoes cause over 700,000 deaths every year.

But there is new hope in the battle between man and mosquito. Scientists at Auburn University, in Alabama, may have found the secret to stopping mosquito-borne diseases. “We have created a type of fabric that blocks mosquito bites,” says John Beckmann, who leads the lab at the university,

Beckmann remembered a camping trip from which he returned riddled with kisses from mosquitoes despite wearing a long-sleeved shirt. “People say, ‘wear long sleeves’ a lot,” Beckmann said, “but long sleeves don’t block mosquitoes.”

While some companies are making what they state is bite-proof clothing, the clothing includes some harmful chemicals or is made of thick fabrics that are too hot to wear and are easily beaten by mosquitoes. That’s because there are holes in the makeup of their fabrics that mosquitoes and other biting insects can get through.

The key is to discover a fabric that can remove these holes and is still cool enough to wear in hot weather. “That is the reason why this project is not as easy as people think” said Beckmann. “You obviously need your clothes to be breathable. But that usually comes at the cost of letting mosquitoes bite through them. So the basic problem is keeping the holes there while blocking tiny mosquito mouth-parts at the same time.”

The team tried by using a computer numerical control knitting (编织) machine that could be programmed with different designs until they found a bite-proof one. The end result is a product that the researchers compare to popular high-quality athletic wear.

But the researchers are still not satisfied and will be spending the next year perfecting the comfort of the material and finally creating a clothing line. The hope is that finally any type of fabric can be knitted into the lab’s design, so that all kinds of clothing companies from baby clothing producers to dress designers could create bite-proof clothing.

8 . Roald Hoffmann, a Nobel Prize winner in chemistry, poet and playwright (剧作家), is a tireless advocate of the wonders of science and the beauty of chemistry. Hoffmann successfully shares his understanding of science with the public at large through literature, educational television and even the stage. Here is an article he wrote:

Around the time of the Industrial Revolution, science left poetry. Nature and the personal became the main playground of the poet. That’s too bad for both scientists and poets, but it leaves lots of open ground for those of us who can move between the two. If one can write poetry about being a tree, why not about being a scientist? It’s experience, a way of life. It’s exciting.

The language of science is a language under stress. Words are being made to describe things that seem indescribable in words — equations (方程式), chemical structures and so forth. Words do not, cannot mean all that they stand for, yet they are all we have to describe experience. By being a natural language under tension, the language of science is inherently (内在地) poetic. Emotions emerge shaped as states of matter and more interestingly, matter acts out what goes on in the soul.

One thing is certainly not true: that scientists have some greater insight into the workings of nature than poets. Interestingly, I find that many humanists deep down feel that scientists have such inner knowledge that they don’t. Perhaps we scientists do, but in such carefully circumscribed pieces of the universe, poetry flies high, all around the tangible (有形的), in the deep dark, through a world we reveal and make.

It should be said that building a career in poetry is much harder than in science. In the best chemical journal in the world, the acceptance rate for full articles is 65%, for communications 35%. In a routine literary journal, far from the best, the acceptance rate for poems is below 5%.

Writing has become increasingly important to me. I expect to publish four books for a general or literary audience in the next few years. Science will be involved, but only as a part, a vital part, of the risky project of being human.
