5 . In Shark Bay, Australia, bottlenose dolphins that aren’t related have been observed teaching each other a new way to use a tool, a behavior that until now scientists have found only in humans and other great apes. It’s also the first known example of dolphins passing on such knowledge within the same generation, rather than between generations. That’s significant, the authors say, because such social learning between peers is rare in nature.
In a practice called shelling, dolphins will chase fish into abandoned giant snail shells on the seafloor, then bring the shells to the surface and shake them with their noses, draining the water and catching the fish that fall out. In 2007, Krutzen launched a study of Shark Bay’s dolphins, identifying more than a thousand individual dolphins over 11 years. During this time, scientists observed shelling 42 times among 19 dolphins. Half of these events occurred after a marine heatwave in 2011, which may have caused a die-off among giant sea snails, leading to more abandoned shells on the seafloor.
Because of the length of their study, scientists had thorough knowledge of the individual dolphins, family histories, ages sexes, and behavior, making it easier for them to study the 19 dolphins that practiced shelling. For instance, they observed that the dolphins that practice shelling hang out with other shelling hunters, so it’s likely that they copy the action from those they spend time with, says study lead author Sonja Wild, a postdoctoral researcher at the University of Konstanz in Germany. Although 42 observations are a small data set, the scientists add it’s likely the behavior is actually common; it only lasts a few seconds, making it harder for people to spot it from a boat.
The team had assumed that environmental factors — specifically, whether shelling dolphins did so simply because they lived in a shell-rich area — could explain this peer-to-peer transmission (传递). A genetic trait (遗传特性) among a family group was another possible reason.
So the researchers combined their data on the dolphin sightings, as well as genetic and environmental data, into a computer model that proposed various ways shelling could be passed on between dolphins. The model that supported this kind of transmission was the strongest outcome, according to the study.

6 . Rolling electric power blackouts afflicted(困扰) roughly 2 million California residents in August, 2020 as a heat wave gripped(影响) the Golden State. At the center of the problem is a state policy requiring that33 percent of California’s electricity come from renewable sources such as solar and wind power, rising to a goal of 60 percent by 2030. Yet data showed that power demand peaks just before the sun begins to go down, when overheated people turn up their air conditioning in the late afternoon. Meanwhile, the power output from California’s wind farms in August was erratic.
California electricity grid operators warned that power shortages might become increasingly common when heat waves hit in the coming years. California still has some natural gas power plants that can be ramped up to(提高) supply energy when renewable supplies fail. “But some folks in the environmental community want to shut down all the gas plants,” Jan Smutny-Jones, CEO of the Independent Energy Producers Association, a trade association representing solar, wind, geothermal, and gas power plants, said in August, 2020. “That would be a disaster. 60 percent of the power in the California Independent System Operator electricity network was being produced by those gas plants in this summer. They are your insurance policy to get through heat waves.”
Union of Concerned Scientists analyst Mark Specht, by contrast, said that “The solution is definitely not more natural gas plants. Really, if anything, this is an indication that California should speed up its investments in clean energy and energy storage.”

10 . 4 Things to Expect from Your Peer Tutoring Session
Peer tutoring is one of the most helpful tools to use during your college years. Sometimes you will not have all the answers and that you may need help from time to time. There is probably no better way to get some academic assistance than that from your fellow students.
●
This will probably be the most uncomfortable part of the session. However, we simply want you to be the best of the best to your best ability. Accept that you are not perfect and that you will make mistakes. Feel fortunate that your peer tutor is recognizing your defects frankly and giving you a chance to repair them.
● Expect change
●Expect discipline (sometimes)
Sometimes we all try to get by with a little less. We are human, after all. It’s nothing to be ashamed of.
●Expect improvement
Last but not least, expect to improve. Peer tutoring can be difficult and intimidating (令人胆怯的), but ultimately the goal is for you to improve as a student in a variety of areas.
A.Expect constructive criticism |
B.Expect reconstruction of self-cognition |
C.A tutor is strict with you not because he wants to be mean and ruin your existence |
D.Peer tutors are understanding, helpful and honest enough to help you out through any obstacles |
E.However, if tutors notice that you have been loosening up, do not be surprised if they call you out on it |
F.You will leave the appointment with a changed perspective on your work and your method of completing it |
G.Once practicing what you have learned in the session, you will notice a great change in your grades and your learning ability |
