New research finds surprising differences in the diets and gut microbiomes of songbirds living in the radiation-contaminated areas of the Chornobyl Exclusion Zone, Ukraine. This study is also the first to examine the breeding behavior and early life of birds growing up in radiologically contaminated habitats. New research finds surprising differences in the diets and gut…
The hot-end components of high-performance high-speed aircraft need to meet performance requirements such as long service life, wide temperature range oxidation resistance and ablation resistance. This puts forward higher requirements for high-temperature service performance of thermal protection system (TPS). The hot-end components of high-performance high-speed aircraft need to meet performance requirements such as long service life,…
Identical wording placing limits on the export of quantum computers has appeared in regulations across the globe. There doesn’t seem to be any scientific reason for the controls, and all can be traced to secret international discussions Identical wording placing limits on the export of quantum computers has appeared in regulations across the globe. There doesn’t…
New experimental research shows that muscle metabolic activity may be an important factor in the incredible longevity of the world’s oldest living vertebrate species—the Greenland shark. These findings may have applications for conservation of this vulnerable species against climate change or even for human cardiovascular health. New experimental research shows that muscle metabolic activity may be…
Using NASA’s Chandra X-ray spacecraft, astronomers from the University of Alabama in Huntsville have observed a merging galaxy cluster known as SPT-CLJ 2031-4037. They detected a rarely seen strong shock front in this galaxy cluster. The finding was reported in a research paper published June 27 on the pre-print server arXiv. Using NASA’s Chandra X-ray spacecraft,…
Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA. Within a few hundred milliseconds, the DNA double helix unwinds to form a node known as the transcription bubble, so that one exposed DNA strand can be copied into a complementary RNA strand. Every living cell…
The advent of quantum computers promises to revolutionize computing by solving complex problems exponentially more rapidly than classical computers. However, today’s quantum computers face challenges such as maintaining stability and transporting quantum information.
