The Beijing-Arizona Sky Survey (BASS) team of National Astronomical Observatories of Chinese Academy of Sciences (NAOC) and their collaborators of the Dark Energy Spectroscopic Instrument (DESI) project released a giant 2D map of the universe, which paves the way for the upcoming new-generation dark energy spectroscopic survey.
Modern astronomical observations reveal that the universe is expanding and appears to be accelerating. The power driving the expansion of the universe is called dark energy by astronomers. The dark energy is still a mystery and accounts for about 68% of the substance of the universe.

Even with the COVID-19-related small dip in global carbon emissions due to limited travel and other activities, the ocean temperatures continued a trend of breaking records in 2020. A new study, authored by 20 scientists from 13 institutes around the world, reported the highest ocean temperatures since 1955 from surface level to a depth of 2,000 meters.
The report was published on January 13 in
Advances in Atmospheric Sciences and concluded with a plea to the policymakers and others to consider the lasting damage warmer oceans can cause as they attempt to mitigate the effects of climate change.

The first ever echidna genome and a greatly improved, high-quality platypus genome have been sequenced by an international team of researchers.
The findings, published in Nature, were produced by 40 researchers from Australia, China, Japan, the US, and Denmark, including from the University of Sydney.
University of Sydney lead, Professor Katherine Belov from the School of Life and Environmental Sciences, said that through this research, she and the team “discovered new peptides” in both the platypus and echidna genomes. These peptides have the potential to be developed into novel drugs for humans and other animals due to their potent antimicrobial activities. “Their potential for biomedical applications is so excit

Chinese scientists from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences (CAS) have found a gene that plays an important role in helping rice adapt to low soil nitrogen.
Nitrogen fertilizer application is a strategic challenge for sustainable agriculture: On the one hand, it plays an indispensable role in increasing crop yields, thus ensuring global food security. On the other hand, it creates a severe threat to ecosystems. For this reason, breeding new crop varieties with high nitrogen use efficiency (NUE) is a high priority for both agricultural production and environmental protection.
