In this episode, we hear about tool use in monkeys, sleep regulation, marsupial placentas, health campaigns and why science papers are so hard to read.
In this episode, we hear about the ways that junk food affects monkeys, grey hair, empathetic rats, using smart phones to fight COVID-19, and how the slave trade spread disease.
Attenuated anticipatory activity in ventromedial prefrontal cortex is modulated by dopamine D1 receptor density in nucleus accumbens, and accounts for impaired probabilistic reward learning in older adults.
It is technically difficult to identify transport proteins, but here a method is presented that exploits the principle that they are stabilized in detergent solution when they bind their substrate.
The tripartite drug efflux pump AcrA-AcrB-TolC, representative of a wide group of pumps from Gram-negative bacteria, enters a transport-competent state through long-distance conformational changes that switch the channel from a closed to an open state.
Increased expression of Drosophila Tailless (TLX homologue) reverts intermediate progenitors to neural stem cells, inducing tumourigenesis via Asense repression and reflecting mutually exclusive TLX and ASCL1 expression in human glioblastoma.
Fossilized feces (coprolites) of extinct bone-crushing dogs, Borophagus parvus, from late Miocene (6 million years ago) of California demonstrates consumption and preservation of bones in digestive tracts and potential social hunting behavior by these predators.
