A new study carried out by Portuguese and Cape Verdean researchers reveals a shark nursery in the Sal Rey bay (Boa Vista island, Cape Verde): home to juveniles of several endangered species, including the iconic hammerhead shark, this is a unique region in the Eastern Atlantic.

Coprolites (fossil feces) from around 30,000 years ago have been used to identify the presence of bearded vultures (Gypaetus barbatus) at the Paleolithic site of Lagar Velho (Portugal). A comparison of the coprolites found in the excavations with the feces of present-day lammergeyers has confirmed the presence of these animals in the past. The research study, published in the journal Scientific Reports, points out…

Transistors based on semiconductor materials are widely used electronic components with many remarkable properties. For instance, they have a nonreciprocal electrical response, which means that they can isolate two parts of a circuit in such a way that one of the parts (the input section) can influence the other part (the output section), but not the other way around. In addition, transistors can amplify voltage…
