Cat (Felis catus, or Felis silvestris catus, literally “woodland cat”), often referred to as the domestic cat to distinguish from other felids and felines, is a small, typically furry, carnivorous mammal. It is often called house cat when kept as indoor pet or feral/feral domestic cat when wild. It is often valued by humans for companionship and for its ability to hunt vermin. There are more than seventy cat breeds recognized by various cat registries. Cats are similar in anatomy to the other felids, with a strong flexible body, quick reflexes, sharp teeth and retractable claws adapted to killing small prey. — Wikipedia

Mammalogy is the study of mammals – a class of vertebrates with characteristics such as homeothermic metabolism, fur, four-chambered hearts, and complex nervous systems. Mammalogy has also been known as “mastology,” “theriology,” and “therology.” The major branches of mammalogy include natural history, taxonomy and systematics, anatomy and physiology, ethology, ecology, and management. — Wikipedia

    In autumn 2022 and winter 2023, a total of 20 cheetahs from Namibia and South Africa were introduced to Kuno National Park in India to establish a free-ranging population -- for the first time since their extinction in India 70 years ago. Although the idea may be commendable, getting it right is not so easy. Scientists see shortcomings in the reintroduction plan: In southern Africa, cheetahs live in a stable socio-spatial system with widely spread territories and densities of less than one […]

    Quantum information (QI) processing may be the next game changer in the evolution of technology, by providing unprecedented computational capabilities, security and detection sensitivities. Qubits, the basic hardware element for quantum information, are the building block for quantum computers and quantum information processing, but there is still much debate on which types of qubits are actually the best.

    Quantum computing uses the principles of quantum mechanics to encode and elaborate data, meaning that it could one day solve computational problems that are intractable with current computers. While the latter work with bits, which represent either a 0 or a 1, quantum computers use quantum bits, or qubits—the fundamental units of quantum information.

    Use of sodium fluoroacetate poison baits—commonly known as 1080—to kill unwanted animals is widespread in Australia. But it occurs largely out of sight and out of mind. We may see signs warning the baits have been laid, but we rarely see the consequences.

    According to Patrick Hanson, the CEO of Luxaviation, a Luxembourg-based luxury airline firm, having pets can be just as polluting as traveling by private jet. In defense of his own industry, he declared recently that one of his company's customers produces around 2.1 tons of CO₂ each year, roughly the same emissions as three pet dogs. This comparison draws on a calculation made in 2020 by carbon-footprint researcher Mike Berners-Lee.
