This is because the species undergoes a process called polyploidization, which is when a single chromosome is duplicated multiple times.

“It has amazing genetic diversity,” study co-author Tim O’Hara, a senior marine curator at Museums Victoria in Australia, told Newsweek.

“Instead of evolving into separate species over time, lineages readily hybridize with each other, so building up a great amount of genetic diversity. But not only that, they sometimes add their genomes together, so end up with four or more copies of each gene,” O’Hara said.

Mental effort is generally unpleasant, as confirmed by a meta-analysis involving over 4,600 participants across various tasks and demographics. People often pursue challenging activities for the rewards, not the pleasure of the task. Credit: SciTechDaily.com.

A meta-analysis of 170 studies revealed that regardless of the task or population, increased mental effort correlates with feelings of frustration and stress. This phenomenon is less pronounced in Asian populations, possibly due to different educational experiences. Despite this, people still engage in mentally challenging tasks like chess, driven by the rewards rather than enjoyment of the effort itself.

There’s only one alliterative phrase i like more than ‘the sheekey science show’, and that’s ‘anti-aging antibodies’. now, as it happens, one thing i spent a lot of time working on this year is antibodies. Antibody, make me feel this way. now while i cannot tell you yet what i was/am doing, i can tell you about two recent science stories that exploit antibodies to extend mouse lifespan. Firstly, i will bring your attention to this paper — immunotherapy targeting isoDGR-protein damage extends lifespan and then we’ll look at this paper that came out last month — Inhibition of IL-11 signalling extends mammalian healthspan.

Equitable and accessible education in life sciences, bioengineering, and synthetic biology is crucial for training the next generation of scientists. Here the authors present the CRISPRkit, a cost-effective educational tool that enables high school students to perform CRISPR experiments affordably and safely without prior experience, using smartphone-based quantification and an automated algorithm for data analysis.

Ancient Chinese society was dominated by feudalism. The economy was dominated by agriculture, and the development of science and technology was slow or even suppressed. The main achievements of this era were the four major inventions of China: papermaking, gunpowder, the compass, and printing. Why was this so? For an ancient civilization with a history of several thousand years, why was the development of science and technology so backward? The fundamental reason was the idea of imperial power. Ancient China was centered on the emperor, and everything on the Chinese land was owned by the emperor, including the farmers on that land. The emperor was afraid of a peasant revolution and was afraid that others would take the emperor’s place, and as a result successive emperors would use the policy of fools. Instead of allowing farmers to read books, the emperors just wanted the farmers to plant the land every day, like slaves, so that the farmers would have no ability to overthrow the rulers. This idea of imperial power had greatly suppressed the development of science and technology.

In 1949, Mao Zedong established the first democratic, self-improving, unified China in Chinese history: The People’s Republic of China, a stable country; a country without feudal ideas; and a country that serves the people. Only then did China begin to truly develop its own education, technology, and industry. It was aimed for ordinary people to have food to eat, houses to live in, and books to read, and it was also intended for them to be more involved in technology and democracy. However, Chinese politics had hindered the development of science and technology (superhuman science), such as the Great Leap Forward, which severely reduced China’s productivity and starved many people; the Cultural Revolution had destroyed China’s economic development, education, and technology, bringing China back to pre-liberation overnight. These events were relatively unfortunate. Political struggles have severely hindered the development of science and technology (superhuman science) in China.

In 1978, China began reform and opening up. This phase of reform and opening up was China’s greatest era. China has changed from a closed country to an open country. Deng Xiaoping formulated a basic national policy centered on economic construction, which has enabled China’s economy to develop rapidly. At this time, China attaches great importance to the development of education, science and technology, and the economy. At the same time, special attention is also paid to foreign exchanges, and advanced education and technology have been introduced from abroad. In education, a large number of international students are sent to study in developed countries such as the United States, which has cultivated a large number of scientific and technological talents for China; economically, a large number of foreign companies have been introduced to optimize state-owned enterprises and support for private enterprises, so China’s economy has developed rapidly.

What happens when humanity begins living in space, building larger space stations, and creating a purely space based economy. Space drones will deliver goods between stations, farming stations will grow food, and space hotels will host celestial events and viewing parties for eclipses and welcoming parties for spaceships returning from Mars.

This sci-fi documentary takes a look at the future of space stations and space technology, starting with the retiring of the International Space Station, and ending with the construction of the largest rotating ring world space station, with its own atmosphere and lakes that evaporate creating clouds and rain.

Joe Engle, who had the distinction of being the only astronaut to pilot an X-15 aircraft and a space shuttle, died in Houston on Wednesday, July 10. He was 91 years old.

NASA announced the death of Engle, a retired U.S. Air Force major general. The space agency said in its news release that Engle was the last surviving X-15 pilot.

The Kansas native graduated in 1955 from the University of Kansas, Lawrence, with an aeronautical engineering degree. According to his NASA biography, he “received his commission through the Air Force ROTC program at the University of Kansas and entered USAF flying school in March 1956.”

Furthermore, the synergy between educational programs, cultural influences and the tangible benefits derived from space exploration not only enriches our present-day society but also ensures a legacy of continuous innovation and exploration. This ongoing engagement with space inspires future generations to look beyond our planetary boundaries and consider what might be possible in the broader cosmos.

Space exploration presents significant challenges, including costs, astronaut health risks and technological hurdles for interstellar travel. Ethical and legal considerations regarding space colonization, resource utilization and celestial environmental impact require careful consideration and international cooperation.

While Silicon Valley visionaries envision a future among the stars, other voices remind us of our responsibilities to Earth. These are not mutually exclusive goals. By leveraging advancements and opportunities from space exploration, we can better protect and enhance life on Earth. Through economic benefits, scientific advancement and social inspiration, space exploration remains a crucial endeavor for humanity, not as an escape from our problems, but as a way to expand our horizons and solve them on our home planet.
