4 . My long-distance cycling career of 13 years and 35,000 kilometres ended as I approached 75 in 2019. The realisation of this dawned on me slowly during my last ride in the US summer of that same year. Although I am now no longer strong enough to endure the long days and big climbs, day in and day out, I have my memories.
Long distance cycling brings pain, anxiety and exhaustion, but these pale into insignificance compared to the joy and satisfaction of climbing huge mountains or seeing spectacular sights for the first time. Real joy would come when I was alone, on my bicycle, in some remote and beautiful place. You could say that these same feelings could have been experienced in a car, but I know this not to be true. I had time to observe nature and life, all of which would have been bypassed in a car.
I enjoyed meeting and beating the daily schedule I had set for myself. I enjoyed the ever-changing vegetation, the people, kind, unkind and indifferent, whom I met along the way. No matter how hard or easy the ride was, I always enjoyed the achievement of arriving, followed by a hot shower and bed, when I could find a motel. On the other nights, I was happy to camp. Meeting a diversity of people with different perspectives on life was easy. The cycling devices allowed me to strike up conversations in pubs and cafes and I got to see and experience the very best in people.
The road ahead always loomed large, as did the mountains, the cold, the mosquitoes and the rain. The road behind is just memories, lack of pain and anxiety, some soon to be forgotten, others to be valued and boosted with the retelling.
Cycling taught me to like who I am. I am finally happy with and accepting of my introverted (内向的) personality. I have more persistence and courage than I ever imagined. These trips all required courage, courage which I never knew I possessed.

5 . In a world where fire threatens more and more homes, scientists have developed a surprising type of material that might keep some buildings safer: thin sheets of fungi (真菌).
Underneath every mushroom is a branching network of root like structures called a mycelium (菌丝体). Now researchers have successfully grown these networks into pizza-size sheets that could act as a fire retardant in building materials, according to a new study in Polymer Degradation and Stability.
“Using a biological material like mycelium has enormous benefits”, says senior author Everson Kandare. Unlike asbestos, which is still sometimes added to building materials as a fire retardant, mycelium does not release poisonous compounds when exposed to fire. “When there is a building fire, it often isn’t the flame intensity or the heat that kills or injures people,” says Kandare, an engineer at RMIT University in Melbourne, Australia. “It is the smoke and the poisonous metal that comes out of building materials.”
The new mycelium sheets, grown into protective carpets up to a few millimeters thick, could prevent such building materials from burning in the first place. Mycelium contains a lot of carbon. When exposed to fire, the sheet briefly burns, releasing water and carbon dioxide into the air, leaving behind a black layer of carbon.
This study is the first to integrate these properties into a useful building material. Kandare suggests mycelium could replace the fire retardant foam (泡沫剂), which can produce CO and other poisonous products when it burns.
The RMIT team has been reaching out to mushroom farmers to see whether they could promote the technology for commercial use. Kandare says, “Mycelium can grow in the dark, which means its energy needs are relatively minimal. Even better, mycelium is a biological material, and any waste it leaves behind can be used as fertilizer.”

7 . You might have heard the theory that a meteor (a huge rock from space) destroyed most life on Earth, including many dinosaurs, 66 million years ago. However, scientists have come up with a reason why this caused so many species to go extinct.
Earlier, scientists had argued that the meteor strike caused wildfires, earthquakes and tsunamis, which destroyed habitats all over the planet and made it impossible for many creatures to survive. However, the new report suggests that more attention should be given to another effect of the meteor — the trillions of tons of dust that were sent flying into the air.
This dust would have gone around in dark clouds, blocking out (封锁) the Sun and causing temperatures around the world to drop sharply. Plants, which need sunlight to live and grow, would have died, leaving animals that eat plants without food. When they died, animals that eat other animals would have had no food either. This led to the extinction of 75% of species on Earth, including most dinosaurs — although the ones that survived later became birds.
The researchers tested their theory by running computer simulations (模拟) of the effect of the meteor strike. These simulations took into consideration real measurements of dust caused by the meteor effect, taken from a site in North Dakota, US. The simulations suggested that the dust could have stayed in the atmosphere for up to I5 years after being thrown into the sky.
Philippe Claeys, co-author of the new research, said that although the meteor strike was disastrous for the dinosaurs, it probably helped humans of the future. “Dinosaurs dominated (统治) the Earth and were doing just fine when the meteor hit,” he said. “Without the impact, my guess is that mammals (哺乳动物) — including us — had little chance to become the dominant creature on this planet.”
