Sir David Attenborough is set to host a brand new natural history series, named A Perfect Planet. The noted documentarian is back, and will be starring in a five-part BBC One series which will take a look at “the intricate（复杂）systems” that allow Earth to boom.
The show is set to explain how the planet operates, looking at everything from ocean currents to solar energy to the weather, and risking all around the world, from India to the Arctic.
Plus, in showing how the earth works, the documentary will also seek to display how animals adapt to their natural environments as they continue to change. As ever, it sounds like a truly fantastic watch.
It won’t be a surprise to hear that the new Attenborough series is set to feature some wonderful film scenes, too.
Speaking of the brand new series, from Our Planet producers Silverback Films, Sir David said: “Oceans，sunlight, weather and volcanoes - together these powerful yet fragile forces allow life to flourish（茂盛）in astonishing diversity. They make Earth truly unique-a perfect planet. Our planet is one in a billion, a world filled with life. But now, a new determining force is changing the face of Earth: humans. To preserve our perfect planet we must ensure we become a force for good.”
While an exact first-show date has not yet been announced, the show is set to land on BBC One later this year.

As the manager for a newly formed team, you want to help your team members get to an effective and high-performing state as quickly as possible.
1. His original model identified four stages that all groups pass through as they move from “newly formed” to “high-performance” teams. Those stages are Forming, Storming, Norming, and Performing.
During the Forming stage, members of the project team meet each other and learn about the tasks they need to perform. 2. During this stage, it is critical for the project manager to provide structure and direction for the team. Clearly defining the project’s objectives and making sure each team member understands their role and responsibilities will help you lead the team through this stage successfully.
The Storming stage is characterized by interpersonal issues such as conflicts. During this stage it is common for team members to challenge each other, including the project manager! Team members may also question what they are doing and how it is being done. As the project manager, this will likely be the most challenging time leading your project. Understanding that this type of conflict is normal for any team will help you pass through this stage successfully. During this stage, some of the skills that help you build your team are conflict management, active listening, and relationship building. 3.
As conflicts become less intense and the team members begin to understand and accept each other, the team will gradually move into the Norming stage. It is during this stage that your team starts to come together and is able to focus more effectively on the project tasks and objectives. 4. Communication and constructive response help you do this. You can continue your team building efforts by arranging social events with the team and making sure to give positive recognition to team members.
5. Interpersonal and structural issues have been settled and support task performance. Team performance is high during this stage.
A.It is also important for you to be confident and positive.
B.Several researchers put forward different theories.
C.In the Performing stage, team members are comfortable with each other.
D.Your behavior has a huge influence on your team members.
E.One of the most influential theories was developed by Bruce Tuckman.
F.You need to focus on keeping everyone moving in the right direction.
G.Team members try to see how they fit in and understand what is expected.
“Jewel wings fly around like little helicopters until they see preys (猎物), usually smaller flying insects,” said Bellido, a biologist at the University of Minnesota. “Then they dash at their meals in a burst of speed.”
You might mistake jewel wings for their cousins, dragonflies. New research shows that these two insects share something more significant than their appearance, however. In a paper published in Current Biology, Dr. Bellido and the dragonfly colleagues reveal that the neural (神经的) systems behind jewel wings’ vision are shared with dragonflies, with whom they have a common ancestor that lived before dinosaurs. But over the centuries, this brain wiring has adapted itself in different ways in each creature, enabling sharply different hunting strategies.
Jewel wings’ behavior involves attacking what’s directly in front of them, the team found. But recordings made in the lab by Dr. Gonzalez and her colleagues confirmed that dragonflies rise up in a straight line to seize unsuspecting insects from below. Researchers are particularly interested in the neurons (神经元) that send visual information to the wings.
To look closer at the neurons linking vision and flight, the researchers equipped jewel wings with sensors and showed them a video of a moving dot, comparing it with earlier dragonfly research. When a neuron fired, a popping sound filled the researchers’ ears, allowing them to tell exactly which movements-left, right, up, down or some combination-each neuron responded to. Jewel wings best see what’s right in front of them, they found, while dragonflies’ clearest vision is just above them.
The team was interested to find that while jewel wings’ neurons didn’t always respond like those in dragonflies, the number of neurons and organization were similar. That suggests that the system that conveys this information from the eyes to the wing muscles did not evolve recently, but has roots that are millions of years older than the oldest dinosaurs. And that ancient common ancestor likely had already developed remarkable speed in both vision and flight. Then, in the following years, the system has evolved to suit individual insect species.
This shared neural system may be more than 250 million years old, but it is also flexible enough to transform itself to meet the needs of a variety of creatures in different eras and environments, the findings suggest.
