Antiferromagnetism is a type of magnetism in which parallel but opposing spins occur spontaneously within a material. Antiferromagnets, materials that exhibit antiferromagnetism, have advantageous characteristics that make them particularly promising for fabricating spintronic devices.

A team of researchers at the University of Tasmania has determined why feral cats are such a threat to wildlife in Australia. In their paper published in Proceedings of the Royal Society B, the group describes comparing the behavior of feral cats in Tasmania with a native predator—the spotted-tail quoll—and what they learned from it.

A team of researchers from Potsdam University and Kazan Federal University has found evidence of a previously unknown kind of star in nebula IRAS 00500+6713. In their paper published in the journal Astronomy & Astrophysics, the group describes their study of the nebula and its central star and what they believe it represents.

Using data from ESA's XMM-Newton and NASA's Swift spacecraft, astronomers have conducted a detailed temporal and spectral study of an eclipsing supergiant X-ray binary known as IGR J18027–2016. Results of this research provide important insights into the properties of this system. The study was published December 28 on arXiv.org.

There is a sense in which the information encoded in a gene sequence can be represented by two bits per base pair location. The reality, however, is that this is far from a complete description. Although many academically and medically interesting things might be done from the minimalist sequence data, no real organism is going self-construct in developmental real time at this data rate no matter how much parallelism is used.

China's delayed carbon trading system will start operating in February, the environment ministry has said, as the world's biggest polluter takes steps towards decarbonising its economy by 2060.

While humanity is facing the COVID-19 pandemic, the citrus industry is trying to manage its own devastating disease, Huanglongbing (HLB), also known as citrus greening disease. HLB is the most destructive citrus disease in the world. In the past decade, the disease has annihilated the Florida citrus industry, reducing orange production for juice and other products by 72%. Candidatus Liberibacter asiaticus (CLas) is the microbe associated with the disease. It resides in the phloem of the tree and... Читать дальше...

A team coordinated by two CNRS researchers and involving colleagues from Sorbonne University, Toulouse III–Paul Sabatier University, the University of Western Brittany and Aix-Marseille University, will traverse the Southern Ocean from January 11 to March 8, 2021, aboard the Marion Dufresne II research vessel chartered by the French Oceanographic Fleet. Their goal is to better understand the sequestration of atmospheric CO2 in the ocean, and especially how the chemical elements essential to this storage are supplied... Читать дальше...
