Buff-tailed bumblebees (Bombus terrestris) are able to use differences in floral humidity to distinguish between rewarding and non-rewarding flowers, according to new research led by biologists from the University of Bristol and the University of Exeter. By experimentally varying the levels of floral humidity in artificial flowers within a range …

Using a combination of MRI, micro-CT and minimally invasive gene analysis, a team of biologists from the Institut für Evolutionsbiologie und Ökologie at the Rheinische Friedrich-Wilhelms-Universität has discovered a new species of dumbo octopus — named Grimpoteuthis imperator — living in the northern part of the Emperor Seamounts, an undersea …

Biologists have analyzed T cells from the gray short-tailed opossum (Monodelphis domestica) and uncovered a previously unknown lineage, called γµ T cells, in the marsupial’s spleen.

A team of biologists from the Wellcome Sanger Institute, the European Bioinformatics Institute and the Universidad de los Andes has identified 142,809 species of bacteriophages — viruses that infect and replicate in bacteria — living in the human gut. Camarillo-Guerrero et al. introduce the Gut Phage Database, a collection of …

Marine biologists working with the Sea Shepherd Conservation Society believe that they have discovered a previously unknown species of beaked whale in the waters north of Mexico’s San Benito Islands.

101.5-Million-Year-Old Microbes A team of biologists from Japan and the United States has successfully revived aerobic microbes found in 101.5-million-year-old sediments from the abyssal plain of the South Pacific Gyre, the part of the ocean with the lowest productivity and fewest nutrients available to fuel the marine food web. Magnified …

An international team of marine biologists, led by researchers at Northeastern University and the University of Utah, is the first to investigate a never before studied species — the giant mud-dwelling shipworm Kuphus polythalamia. According to the researchers, this marine animal doesn’t seem to eat much; instead it gets its …

A team of researchers at the University of Warwick, UK, has identified Connexin26 (Cx26) as a key molecule that reacts to carbon dioxide (CO2) in our bodies and activates breathing. The study is published in the journal Proceedings of the Royal Society B. CO2-dependent dye loading of HeLa cells expressing …
