Detailed bedbug genome analysis may improve pesticides

University of Texas at Arlington
Peer-Reviewed Publication

Thanks to a new University of Texas at Arlington study published in the Journal of Heredity, scientists now have a better genetic understanding of the insect. The research offers an updated genome analysis of the common bedbug Cimex lectularius, providing new insight for those working to prevent bedbug infestation, develop remediation strategies and track pesticide resistance.

Simple enrichment reduces boredom and boosts welfare in housed dairy cows

Understanding dairy cow behavior has been a hot topic of dairy science research in the last few decades. In a special issue of JDS Communications dedicated to behavior in dairy animals, a new study highlights the importance of environmental enrichment for improving the welfare of housed dairy cows. Researchers at the University of Nottingham found that introducing a simple novel object into the cows’ environment can significantly reduce boredom-associated behaviors, make the environment more engaging, and help the dairy science community better understand the effects of housing on behavior.

Bioengineered yeast microbes as targeted drug delivery systems

Human civilization at a critical junction between authoritarian collapse and superabundance

System Shift Lab
Peer-Reviewed Publication

A new scientific study published in the journal Foresight concludes that human civilisation is on the brink of the next ‘giant leap’ in evolution. However, progress could be thwarted by centralised far-right political projects such as the incoming Donald Trump administration.

"Industrial civilisation is facing 'inevitable' decline as it is replaced by what could turn out to be a far more advanced ‘postmaterialist’ civilisation based on distributed superabundant clean energy. The main challenge is that industrial civilisation is facing such rapid decline that this could derail the emergence of a new and superior 'life-cycle' for the human species", commented Dr Nafeez Ahmed, author of the paper, member of The Club of Rome, member of the Earth4All Transformational Economics Commission and Distinguished Fellow at the Schumacher Institute for Sustainable Systems.

Yeast as food emulsifier? Easily released protein as strong as casein

Osaka Metropolitan University
Peer-Reviewed Publication

An Osaka Metropolitan University research team has discovered proteins with emulsifying action that can be readily released from yeast cell walls. One of them exhibited emulsifying activity comparable to that of casein, a milk-derived emulsifier.
