Antonio Acín, Lluis Masanes | Safeguarding pollinators and their values to human well-being
Wild and managed pollinators are threatened by pressures such as environmental changes and pesticides, leading to risks for pollinator-dependent crop production, meaning more research and better policies are needed to safeguard pollinators and their services.
Simon G. Potts, Vera Imperatriz-Fonseca, Hien T. Ngo et al. | | Gamma frequency entrainment attenuates amyloid load and modifies microglia
Mouse models of Alzheimer’s disease show reduced, behaviourally driven gamma oscillations before the onset of plaque formation or cognitive decline; driving neurons to oscillate at gamma frequency (40 Hz) reduces levels of amyloid-β peptides.
