A Key Player Behind Parental Chromosome Matching During Meiosis

Researchers have clarified how homologous chromosome pairing -- a process necessary for sperm and egg formation where paternally- and maternally-derived chromosomes match and exchange genetic ...

How Cell Processes Round Up and Dump Damaged Proteins

Reporting unexpected processes, chemists say they have discovered how an enzyme known as UCH37 regulates a cell's waste management ...

Host Genetic Factors Shape Composition of Virus Communities

Plants can be infected by multiple viruses at once. However, the composition of the pathogen community varies, even if individuals belong to the same species and the same population. Ecologists have ...

Model for Acid-Tolerant Yeast Helps Guide Industrial Organic Acid Production

Microbes and other microscopic organisms could serve as sustainable 'factories' to create many types of industrial materials because they naturally convert nutrients such as sugars into ...

'BAH-Code' Reader Senses Gene-Silencing Tag in Cells

Researchers have identified an evolutionarily conserved pathway responsible for 'closing down' gene activity in the mammalian cell. The finding is closely related to the Polycomb pathway ...

Beetle Larvae Think With Brain 'Under Construction'

In human brains, hundreds of billions of nerve cells are interconnected in the most complicated way. This is no different for insects, although their brains 'only' have up to one million ...

Researchers Discover Mechanism That Allows SINEUPs to Amplify Protein Production

Scientists have discovered that a pair of proteins play a key role in allowing an important type of functional non-coding RNA, known as SINEUPs, to act to promote their target messenger ...
