The universe may not be endless

The universe may not be endless
Physicists used to imagine the shape of the universe. Now, a new study analyzes data from Planck satellites and points out that the universe may be a closed three-dimensional sphere, and this new conclusion comes to a key factor that determines the shape of the universe: the critical density of the universe. Simmons Observatory, currently under construction in Chile, and Ali’s Universe Microwave Background Radiation Polarization Detector in Tibet, China, will provide more accurate measurement data. Perhaps in the next 5 years, from the observation data of these devices, we can re-understand this cosmic space.

China successfully launches the 49th Beidou navigation satellite
At 1:43 on November 5, 2019, China successfully launched the 49th Beidou navigation satellite with the Long March IIIB carrier rocket at the Xichang Satellite Launch Center. The successful launch of the satellite marked the completion of the launch of all three oblique geosynchronous orbit satellites of the Beidou-3 system. The Beidou navigation satellite and the supporting launch vehicle launched this time were developed by the China Academy of Space Technology and the China Academy of Launch Vehicle Technology respectively under the China Aerospace Science and Technology Corporation. This is the 317th flight of the Long March series carrier rocket.

Gene therapy can treat multiple age-related diseases simultaneously
Harvard University and Harvard Medical School have jointly studied an adeno-associated virus-based anti-aging gene therapy that can deliver a combination of three longevity-related genes to mice. The results significantly improved or completely reversed many age-related diseases. Show that this systemic treatment can improve overall health. The results are shocking and suggest that a comprehensive approach to aging through gene therapy may be more effective than the sporadic methods currently available. Everyone wants to stay healthy for as long as possible, and this research is the first step to reducing suffering from debilitating diseases.

Japan develops artificial blood that can be stored for one year
The Japanese research team announced that they have successfully developed an artificial blood that can save the lives of many people. This artificial blood can be stored at room temperature for more than one year, regardless of different blood types. At present, this artificial blood has been successfully tested in experimental rabbits. However, with so many benefits of artificial blood, there is still a long way to go before it is widely used in clinical practice. It is believed that with the continuous development of technology, in the near future, artificial blood can be mass-produced at low cost like normal saline, solve the problem of tight blood supply, and play an important role in treating various blood diseases.

Original innovative drugs provide new solutions for Alzheimer’s disease treatment
A new drug developed by Chinese scientists to treat Alzheimer’s disease has been approved by the State Drug Administration. The drug is listed for the first time in the world. This original innovative drug named “Nine Phase One” is led by a team led by Geng Meiyu, a researcher of the Shanghai Institute of Materia Medica, Chinese Academy of Sciences. R & D success under continued efforts. The results of the study indicate that “Nine Phase One” can significantly improve cognitive dysfunction in patients with mild to moderate Alzheimer’s disease.

Scientists reveal molecular mechanism of sparrow “picking” sorghum
Chinese scientists have discovered that sparrows can also be “picky” on sorghum, and this has revealed the molecular mechanism by which sparrows are “picky” on different sorghum varieties. Sorghum has the characteristics of drought and flood tolerance, salt and alkali tolerance, barren tolerance, and high yield. However, sorghum has a “natural enemy”-the sparrow, which likes sorghum, which will reduce sorghum production. This research result provides important genetic resources for breeding new sorghum bird-resistant varieties, and also provides a brand-new solution for the design and development of new green pesticides to control agricultural bird damage.

Climate warming or extinction of emperor penguins at the end of this century
A new US study has found that if action is not taken to curb the warming trend in time, the largest member of the existing penguin family, the Emperor Penguin, will become extinct at the end of this century. Emperor penguins are mainly distributed in Antarctica and surrounding islands and feed on fish and shrimp. Their destiny is closely related to sea ice: the emperor penguin’s habitat is mainly on sea ice within the Antarctic coastline, and it must be close to the ocean in order to obtain food. The number of Emperor penguins in Antarctica is expected to decrease by 86% by 2100, when the number of emperor penguins is unlikely to pick up and the species will go extinct.

Finnish scientist finds new parasitic bee
Finnish scientists have recently discovered two parasitic bee species that can reach 10 cm in length and can lay eggs in other insects. They do not hurt humans and are harmless to humans, but they are “kings of destruction” in the insect world. These two wasps were found in the jungles of Kibale National Park in Uganda, Africa. These larger parasitic bees are very rare. The scientists were surprised that there are a lot of these two parasitic bees in the Ugandan forest. Tent-like traps successfully captured them, validating this latest finding.
