How smart is an octopus?

The unique brainpower of octopuses—known for their intelligence and Houdini-like escapes—has been revealed by University of Queensland researchers.

Centriole instability might contribute to some cases of microcephaly

Centrioles are cylindrical structures involved in the generation of microtubules—fibers inside of cells that form a network to provide structure and shape to cells and to mediate transport processes. In addition, centriole ...

Male giraffes are more socially connected than females

Although female giraffes have closer "friends" than male giraffes, male giraffes have more "acquaintances" than females, according to a new study by an international team that includes a Penn State biologist. The study demonstrates ...

Wired for efficiency: How methanogenic microbes manage electrons

Methanogenic archaea use sophisticated enzyme systems to live in energy-limited anoxic environments. A key mechanism for saving energy is electron bifurcation, a reaction that 'splits' the energy of a pair of electrons, making ...

Solving a long-standing biological search problem

How the cell can mend broken DNA using another DNA copy as template has puzzled researchers for years. How is it possible to find the correct sequences in the busy interior of the cell? Researchers from Uppsala university ...

AI algorithm solves structural biology challenges

Determining the 3-D shapes of biological molecules is one of the hardest problems in modern biology and medical discovery. Companies and research institutions often spend millions of dollars to determine a molecular structure—and ...
