1 . English businessman Richard Branson made history on July 11, 2021 as he and three other crewmates became the world’s first space tourists. The flight was made by a spacecraft named VSS Unity that was built by Branson’s company, Virgin Galactic. The flight lasted slightly more than an hour, and took Branson and crew to an altitude (海拔) of 53.5miles above the Earth, just a little above the boundary (边界) of space which lies 50 miles above the Earth.
At that height, the atmosphere turns into the black of outer space and the Earth becomes a bent ball of blue. Travelers also exhibit weightlessness as there is no gravity, the force that keeps our bodies walking on the Earth’s surface. Therefore, Branson and his fellows were able to float around in VSS Unity while enjoying the views. They were able to do that for three minutes before the spacecraft began its downward journey. It landed back at Virgin Galactic’s space port in New Mexico, United States, which is the same place from where it had taken off 90 minutes before.
On landing back, Branson said, “I have dreamt of this moment since I was a kid but honestly, nothing could prepare you for the view of the Earth from space. It was just magical. I’m just taking it all in, and it’s unreal.”
July 11’s flight is the start of space tourism for one and all. In early 2022, customers who can afford a ticket for a quarter of a million dollars can line up for a seat on a trip to space. And guess what — they will have a choice of spacecraft. Jeff Bezos, who owns a famous company, is all set to launch himself into space on July 20 on board a spacecraft built by his new branch company Blue Origin. Blue Origin will also carry tourists to space.

2 . If you’ve ever seen a sparrow steal your dog food or a crow open a garbage bag, you get a sense of that some birds have learned to take advantage of new feeding opportunities—a clear sign of their intelligence. Scientists have long wondered why certain species of birds are more innovative than others, and whether these capacities stem from larger brains or from a greater number of neurons (神经元) in specific areas of the brain.
It turns out that it’s a bit of both, according to a recent study by an international team that included members from McGill University published in Nature Ecology and Evolution.
The researchers used a new technique to estimate the number of neurons in a specific part of the brain called the pallium in 111 bird species. The pallium in birds is equal to the human cerebral cortex (大脑皮层), which is involved in memory, learning, reasoning, and problem-solving, among other things. When these estimates about neuron numbers in the pallium were combined with information about over 4,000 feeding innovations, the team found that the species with the higher numbers of neurons in the pallium were also likely to be the most innovative.
“The amount of time chicks spend in the nest as their brains develop might also play a crucial role in the evolution of intelligence,” says McGill University Emeritus Professor Louis Lefebvre who spent more than 20 years gathering examples of feeding innovations. “Larger species of crows and parrots, which are known for their intelligence, spend longer in the nest, which allows more time for the brain to grow and accumulate pallial neurons.”
The results of the study help to deal with previously opposed views of the evolution and significance of brain size and show how a life-history perspective helps to understand the evolution of cognition.

3 . More than 400 athletes across a variety of sports, ages and levels of experience were questioned for the study by sports psychology experts from Staffordshire University and Manchester Metropolitan University. The findings reveal that athletes’ belief systems — specifically irrational (非理性) beliefs — are related to poorer self-confidence, and in turn, greater competitive anxiety and depressive symptoms.
“Phrases that reflect self-depreciating (贬低) beliefs such as ‘If I lose, I’m a failure’ or ‘If I face setbacks, it shows how stupid I am’ are warning signs,” said the authors. Paul Mansell, Lecturer in Sport and Exercise Psychology at Staffordshire University, said, “Despite the psychological benefits of physical activity, studies frequently report poor mental health in athletes, which may be exacerbated by adversities, such as injury, de-selection, and performance pressure. We investigated athletes’ beliefs, how they view stress, their levels of self-confidence and put all this data together to work out what might predict psychological well-being. We found irrational beliefs to be a core reason for symptoms of poor mental health in athletes.”
This is the first known study that has examined irrational beliefs, self-confidence, and the psychological well-being of athletes all together. Irrational beliefs are extreme, rigid, and illogical ideas that people hold. For example, a person might believe that they “must” get what they want, or that just because they have failed, they are a “complete failure”.
“We can all work to help athletes develop mindsets that help them deal with the challenges of sport and life. By encouraging rational and logical beliefs about performance, we can help athletes to stay healthy amidst the high demands of competitive sport,” said Paul Mansell.
The author s propose Rational Emotive Behavior Therapy (REBT) as an effective tool for protecting self-confidence. REBT helps athletes to challenge these self-depreciating beliefs and develop beliefs that are more helpful and healthy. For example, rather than believe “I am a failure if I fail”, this might be countered with “Failing is not ideal, but it does not mean that I am a failure”.
