1 . 2020 was a really tough year. It affected our lives in many ways and made other serious issues even more difficult to address. There was also social and political unrest in the United States and other places around the world.
All of this added up to some big, stressful year called 2020. In fact, 2020 is a song filled with low, depressing notes.
In English, “low notes” are unpleasant things that happen during an event, any event. So if something ends on a low note, it ends in an unpleasant way. For example, once I took a fun vacation. But it ended on a low note. On the last day, all my money was stolen. Then my flight home was delayed. So, I had to sleep in an airport for two days!
However, we also have another phrase-- a “high note”! In English, a “high note” is something pleasant or gratifying.
So, to end something on a high note is to end it with something pleasant. It can also mean to end something at the best possible point -- for example, at the point when something is most successful.
Anything can be a high note, if you choose it to be. For example, 2020 was a disaster. But for me it ended on a high note. One cold night in late December, I saw on owl in a tree near my house. I love owls but had never seen one so close before! That was a high note for me.
Hopefully, all of us were able to end 2020 on a high note.

2 . Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.
Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.
Insect population collapses have been reported around the world, and the first global scientific review published in February, said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".
There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.
The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects are important prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.
The researchers said most human-caused threats to insects have analogues in nature, such as climate change and invasive species. But light pollution is particularly hard for insects to deal with.
However, unlike other drivers of decline, light pollution is relatively easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.

3 . In the delightful presence of adorable little things, it isn’t uncommon to be conquered by a desire to shout “Kawaii”. In Western culture, we’ve come to think of kawaii as a synonym for cute. In Japan, where the kawaii aesthetic (审美) has been its own pop culture phenomenon for decades, the word is a bit more complex.
Nittono, a kawaii researcher, says the Japanese word kawaii was originally an affective adjective that expressed one’s feelings toward an object. “In Japanese, we can say ‘feel kawaii,’” he adds. Visually, kawaii is tied to what researchers call baby schema—a large head, round face, and big eyes—but kawaii involves the other senses too. In a paper published in the journal Universal Access, researchers reported that people also label certain sounds as cute, and those sounds tend to be high pitched, like the chirp (鸣叫) of a baby bird.
Kawaii isn’t always what we would traditionally describe as cute, either. Ugly or strange- looking things can also bring about kawaii feelings, a concept referred to as kimo-kawaii, or “gross cute.”
Put simply, Nittono says, kawaii is the “cute emotion” you experience in the presence of something that elicits that emotion.
Kawaii doesn’t just make us feel good — it changes our behavior. Kawaii is what causes you to pinch (捏) a baby’s cheeks or snuggle (紧抱) a puppy. What’s more, kawaii not only makes you want to physically embrace the cute thing, but also enables a natural need to protect it. Kawaii also influences our feelings and behavior in other ways. It has a calming and healing effect, for instance. It also makes us soft — more easily influenced and open to requests. “I think kawaii, or cute feelings, reminds us of human connection that we sometimes forget,” says Nittono.

4 . JeffBezos has a rule at Amazon, or perhaps more appropriate a philosophy. If a team cannot be fed by two pizzas then that team is too large. The reasoning is quite straightforward and basic. More people means more communication, more bureaucracy, more chaos, and more of pretty much everything that slows things down, hence why large organizations are oftentimes considered as being so inefficient.
In 2013 Gallup released a report called “The State of The American Workplace", in which they found that smaller companies had more engaged employees. In fact,42% of employees working at companies of 10 or fewer were engaged at work versus only 30% of employees at large companies.
Most people are not familiar with the Ringelmann Effect which is the tendency for individual members to become less productive as the size of a group increases. This concept was named after Maximilien Ringelmann, a French professor of agricultural engineering who passed away in 1931.In one of his experiments he asked volunteers to perform a very simple task, to pull on a rope. He found that when only one person is pulling on the rope they give 100% of their effort; however, as more people are added the individual effort goes down.
This experiment was recreated in the 1970's by Alan Ingham who came up with the concept of “social loafing” which helps us understand why the individual effort decreases as the team size increases. So why does this happen? Because it becomes harder to extract the individual contributions and performance of each person.
Organizations should really think about what their team structures look like and create and follow similar “two pizza rules”. It's no coincidence that smaller organizations are oftentimes more nimble while large organizations look like they are stuck in the mud.
