A UPV/EHU study analyses the resistance of the Helicobacter pylori (H. pylori) bacterium to the antibiotics routinely used to treat the infection caused by this bacterium. The study reveals that resistance is very high and suggests that antibiotic misuse is mainly responsible for the increase in resistance in this bacterium.
A team of international researchers from Canada, Colombia, and Germany has discovered a new marine reptile. The specimen, a stunningly preserved metre-long skull, is one of the last surviving ichthyosaurs – ancient animals that look eerily like living swordfish.

Researchers at Shinshu University’s Department of Chemistry attempted to establish technology that enables simple, highly sensitive, and selective screening and analysis of stimulants, namely components of regulated toxicants. The number of arrests for the possession or use of methamphetamine and other illegal substances in Japan has exceeded 10,000 per year, which has become a serious social problem. Therefore, there is high demand in the fields of forensic science and clinical chemistry for simple test methods that can be applied to field analysis for a large number of samples.

Researchers from the University of Tsukuba have observed a male bias in protein expression in primordial germ cells, which develop into the cells that pass on genetic material during reproduction, of the fruit fly, Drosophila. When using the Gal4-UAS system to activate expression of Green Fluorescent Protein (GFP), the team saw that male cells showed higher protein expression than female ones. This may be a cause of the sex differences observed in the early germline.

Study results on whale song suggest that the consensus response to the question of why humpbacks sing is wrong. The whales don’t sing to attract a mate (reproductive hypothesis), according to Eduardo Mercado III, a University at Buffalo professor of psychology. They’re singing to find other whales (sonar hypothesis), using mechanisms within their songs that may be comparable to those at work in the eyes of land animals as they examine their environment. “[This isn’t a] feather in the sonar hypothesis cap? It’s more like an arrow through the chest of the reproductive display hypothesis,” says Mercado.

Snow monkeys living in one of the world’s coldest regions survive by ‘going fishing’ – scooping live animals, including brown trout, out of Japanese rivers and eating them to stay alive, a new study reveals.
