mammal : any of a class (Mammalia) of warm-blooded higher vertebrates (such as placentals, marsupials, or monotremes) that nourish their young with milk secreted by mammary glands, have the skin usually more or less covered with hair, and include humans — Webster
Mammals are the vertebrates within the class Mammalia, a clade of endothermic amniotes distinguished from reptiles (including birds) by the possession of a neocortex (a region of the brain), hair, three middle ear bones, and mammary glands. Females of all mammal species nurse their young with milk, secreted from the mammary glands.
Mammals include the largest animal on the planet, the blue whale. The basic body type is a terrestrial quadruped, but some mammals are adapted for life at sea, in the air, in trees, underground or on two legs. The largest group of mammals, the placentals, have a placenta, which enables the feeding of the fetus during gestation. Mammals range in size from the 30–40 mm (1.2–1.6 in) bumblebee bat to the 30-meter (98 ft) blue whale. With the exception of the five species of monotreme (egg-laying mammals), all modern mammals give birth to live young. Most mammals, including the six most species-rich orders, belong to the placental group. The largest orders are the rodents, bats and Soricomorpha (shrews and allies). The next three biggest orders, depending on the biological classification scheme used, are the Primates (apes and monkeys), the Cetartiodactyla (whales and even-toed ungulates), and the Carnivora (cats, dogs, seals, and allies). — Wikipedia

The quest to discover how new diseases -- such as Covid-19 -- emerge and spread in response to global land-use change driven by human population expansion still contains 'major gaps', researchers have claimed.

An indoor residual spray made by combining a type of volcanic glass with water showed effective control of mosquitoes that carry malaria, according to a new study. The findings could be useful in reducing disease-carrying mosquito populations—and the risk of malaria—in Africa.

Palaeontologists from St Petersburg University have been the first to study in detail the structure of the brain and blood vessels in the skull of the ankylosaur Bissektipelta archibaldi, an herbivorous dinosaur somewhat similar in appearance to a modern armadillo. Scientists produced the first three-dimensional computer reconstruction of a dinosaur endocast made in Russia,a digital cast of its braincase. It made it possible to determine that ankylosaurs, and Bissektipelta in particular, were […]

Parents pass genes along to their offspring traits that equip them for life. In recent years, research has shown that the reality is much more complex and that parents endow much more than just genes. A new study in Cell by the laboratory of Asifa Akhtar at the Max Planck Institute of Immunobiology and Epigenetics reveals that active epigenetic modifications are also passed from one generation to the next.

After a particularly long week of computer based work on my Ph.D., all I wanted was to hike somewhere exciting with a rich wildlife. A friend commiserated with me—I was based at Newcastle University at the time, and this particular friend wasn't keen on the UK's wilderness, its moorlands and bare uplands, compared to the large tracts of woodland and tropical forests that can be found more readily abroad.
