Transposon-encoded CRISPR–Cas systems direct RNA-guided DNA integration

Transposon-encoded CRISPR–Cas systems direct RNA-guided DNA integration

Conventional CRISPR–Cas systems maintain genomic integrity by leveraging guide RNAs for the nuclease-dependent degradation of mobile genetic elements, including plasmids and viruses. Here we describe a remarkable inversion of this paradigm, in which bacterial...

How can governments fight antimicrobial resistance with policy?

How can governments fight antimicrobial resistance with policy?

Governments have a wide variety of policy options at their disposal to respond to the growing threat of antimicrobial resistance, but many of these approaches have not been rigorously evaluated, according to a new...

In romantic relationships, people do indeed have a ‘type’

If you’ve ever come out of a bad relationship and decided you need to date someone different from your usual “type,” you’re not alone. However, new research by social psychologists at the University of...

How do foams collapse?

How do foams collapse?

Researchers from Tokyo Metropolitan University have successfully found two distinct mechanisms by which foams can collapse, yielding insight into the prevention/acceleration of foam rupture in industrial materials e.g. foods, cosmetics, insulation, stored chemicals. When...

Study links sleep-disordered breathing to age acceleration

Study links sleep-disordered breathing to age acceleration

Increasing severity of sleep-disordered breathing and sleep disruption are associated with epigenetic age acceleration, according to preliminary results of a new study. Results show that each standard deviation increase in the apnea-hypopnea index, a...

Disturbed sleep linked to mental health problems in natural disaster survivors

Disturbed sleep linked to mental health problems in natural disaster survivors

Preliminary results from a new study suggest that sleep disturbances are associated with mental health problems among survivors of a natural disaster even two years after the event. The researchers surveyed survivors two years...
