Researchers discover new sex hormone

When University of Ottawa biologists Kim Mitchell and Vance Trudeau began studying the effects of gene mutations in zebrafish, they uncovered new functions that regulate how males and females interact while mating. We sat ...

The ins and outs of sex change in medaka fish

Larval nutrition plays a role in determining the sexual characteristics of Japanese rice fish, also called medaka (Oryzias latipes), report a team of researchers led by Nagoya University. The findings, published in the journal ...

Baking sourdough? Biologist discusses yeast and fermentation

As most people are cooped up at home amid the COVID-19 pandemic, many are occupying their time by baking and experimenting in the kitchen. So much so in fact that baking ingredients—flour, yeast and eggs to name a few—have ...

How filamentous fungi sense food

A team led by researchers at the University of California, Berkeley used a multi-omics approach to reconstruct and model gene regulatory pathways used by the filamentous fungus Neurospora crassa, and to identify and decide ...

Mutation reduces energy waste in plants

To this end, the team identified several thousand proteins, determined their respective amounts in mutant and reference lines and combined the findings with measurements of photosynthetic performance. Their findings were ...

River-groundwater hot spot for arsenic

Naturally occurring (geogenic) groundwater arsenic contamination is a problem of global significance, with noteworthy occurrences in large parts of the alluvial and deltaic aquifers in South and Southeast Asia. To address ...

Model organism

A model organism is a species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms. In particular, model organisms are widely used to explore potential causes and treatments for human disease when human experimentation would be unfeasible or unethical. This strategy is made possible by the common descent of all living organisms, and the conservation of metabolic and developmental pathways and genetic material over the course of evolution. Studying model organisms can be informative, but care must be taken when generalizing from one organism to another.
