Humans can sense five different tastes: sour, sweet, umami, bitter, and salty, using specialized sensors on our tongues called taste receptors. Other than allowing us to enjoy delicious foods, the sensation of taste allows ...
There are fields of scientific research that involve neither vast cosmic phenomena nor extremely cute animals, but those are topics of high salience in Saturday Citations, and this week is no exception. And we'll probably ...
Jaws are bone- or cartilage-based structures that hold together teeth in the mouth of most vertebrates (i.e., all animal species with a backbone or spinal column). While these crucial structures have been the focus of numerous ...
Researchers at Nagoya University and Osaka University in Japan have found novel repair pathways of apurinic/apyrimidinic (AP) sites of DNA. Repair of the base excision, which repairs AP sites, is an essential mechanism for ...
Special cranial adaptations, including an asymmetrical 'wonky' skull and enlarged ears, may give the critically endangered ground-dwelling Night Parrot the edge it needs to make its way around the Outback in the dark— even ...
The CT-scanned skull of a 319-million-year-old fossilized fish, pulled from a coal mine in England more than a century ago, has revealed the oldest example of a well-preserved vertebrate brain.
Fluorescence imaging can be conducted with long Stokes shift dyes that minimize crosstalk between the excitation source and fluorescent emission to improve the signal-to-background ratio. Regardless, researchers still form ...
The human middle ear—which houses three tiny, vibrating bones—is key to transporting sound vibrations into the inner ear, where they become nerve impulses that allow us to hear.
Having a head is quite an advantage. Although this may sound banal, it had to be tested in a long evolutionary process: As animal life developed, invertebrates initially dominated the oceans. These had already developed head ...
Among the fierce carnivores that lived during the late Cretaceous was a predator named Daspletosaurus. The massive tyrannosaur, about nine meters long, lived in the coastal forest of what is now Alberta around 75 million ...
