New yeast model can improve protein production

Microorganisms, such as baker's yeast, can be used as cell factories to produce different chemicals and proteins, such as commonly used pharmaceuticals as insulin. By modifying the cell factories researchers are trying to increase the yield and speed of the production processes. In a new study published in Nature Communications, researchers in systems biology at Chalmers provide us with a new...

Tracing the remnants of Andromeda's violent history

A detailed analysis of the composition and motion of more than 500 stars has revealed conclusive evidence of an ancient collision between Andromeda and a neighboring galaxy. The findings, which improve our understanding of the events that shape galaxy evolution, were presented by Carnegie's Ivanna Escala Monday at the meeting of the American Astronomical Society.

Researchers discover mechanism linking mutations in the 'dark matter' of the genome to cancer

Many sections of the non-coding region of the human genome play a key role in regulating gene activity. But the relationship between non-coding mutations and cancer risk has been a mystery. New research sheds light on that mystery, providing clues that may link mutations to epigenetic changes, and may point to potential drug targets to reduce risk for people born with certain genetic mutations.

Sanctuary practices lower counties' crime rates, study finds

Counties that don't cooperate with Immigration and Customs Enforcement (ICE)—also known as "sanctuary counties"—have seen their crime rates decrease after implementing sanctuary policies, according to a new study from a researcher at The University of Texas at Austin.

Team uses hot water to form photocatalyst

The production of chemical substances normally requires environmentally harmful solvents. After the research group of Miriam Unterlass, professor of solid state chemistry at the University of Konstanz, produced organic substances without harmful substances for the first time by heating them in hot water, the researchers can now chalk up another success: Through hydrothermal synthesis, they...

Shorter, wider flowers may transmit more parasites to bees

North Carolina State University researchers show that the shape of flowers has the biggest effect on how parasites are transmitted to bees, an important consideration for declining populations of our prodigious pollinators. The findings could help stakeholders plant flowers that are less likely to spread parasites in pollinator habitats.
