Scientists at the University of Texas at Austin pointed out in the latest issue of nature that they have developed a new enzyme variant fast petase, which can decompose plastics that normally take hundreds of years to degrade in a few hours to days. It is expected to greatly promote the recycling of plastics and truly open the curtain of plastic circular economy.
It is understood that NASA is planning to bring rocks from Mars to earth. The space agency has sought public opinion on its plan to retrieve samples collected by perseverance. Although many people are excited about this, some scientists worry that alien bacteria will also take the opportunity to come to earth.
Japanese researchers have developed a nano cellulose paper semiconductor, which shows the nano micron macro cross scale designability of 3D structure and the wide adjustability of electrical properties. The research results were recently published in ACS Nano, the core journal of the American Chemical Society. Semiconductor nanomaterials with 3D network structure have high surface area and a large number of pores, which makes them very suitable for applications involving adsorption, separation and sensing.
On May 5, Beijing time, after learning that there was a major paint leakage accident at Tesla Berlin super factory, the environmental protection organization Green Alliance launched an action to revoke the business license of the factory. The delay in obtaining a business license for Tesla Berlin super factory is partly due to environmental organizations, including the green alliance.
On the morning of May 5, it was reported that 580000 \5 women were cheated to use Tiktok as a fitting clerk and went on a hot search on the social platform, @ JuLang video posted that many netizens reported that they were cheated to use Tiktok as a part-time fitting clerk and had similar experiences. They said that she saw the advertisement of the fitting staff on Tiktok and left her contact information. The other party added her wechat, and then began to brush the bill to do the task. Finally, she was cheated step by step. Some netizens left a message saying that the cheater was blatant, and the platform just collected the money and did not review it.

As early as may 2020, the video game series documentary "noclip" shared the picture of "half life 2: Chapter 4" cancelled by arkane studio. Noclip recently shared an hour long new demo video showing the cancelled game.
Sex hormones play an important role in shaping animal behavior, and their role began very early. Hormonal surges early in life help shape the developing brain and establish circuits that will affect behavior throughout life. Hundreds of genes in the brain are controlled by estrogen. In addition to early shaping of developing neural circuits, fluctuations in hormone levels can lead to changes in mood, energy balance and behavior throughout life. These effects occur when activated estrogen receptors are located directly on the cell's DNA to turn genes on or off.
Pan Jianwei and Zhang Qiang of University of science and technology of China cooperated with Wang Xiangbin and Liu Yang of Jinan Institute of quantum technology to develop a set of experimental system integrating quantum key distribution and optical fiber vibration sensing. While completing the distribution of optical fiber double field quantum key, they can realize 658km long-distance optical fiber sensing with positioning accuracy of 1km, which greatly breaks through the limitation that the distance of traditional optical fiber vibration sensing is difficult to exceed 100km. Relevant results were published in Physical Review express on May 2.
Huawei has released a number of 4G mobile phones in the past year. Due to 5g RF chip and other reasons, even if the chip is replaced with Xiaolong 888 processor, it also only supports 4G network. Recently, according to digital blogger @ factory director Guan, Huawei's new nova10 series should adopt a dual core hybrid scheme, namely Xiaolong 778g and Xiaolong 7gen1. At the same time, the software and camera module of this series are adjusted better.
