In this episode, we hear about the emerging field of palaeoshellomics, wasp eggs that keep their food fresh, a monkey with a missing visual cortex, new biological methods inspired by astronomy and how to mix a family with a research career.
Experiments in a mouse model for Alzheimer’s disease using germ-free and conventionally housed animals reveal that microbiota-derived short-chain fatty acids promote the deposition of cerebral Aβ plaques.
Quantitative genetic analyses reveal remarkably broad genetic variation underlies the requirement for two critical regulatory inputs into a core embryonic gene regulatory network within one animal species.
Heme accumulation is toxic, but deficiency of the heme transporter HRG1/SLC48A1 causes heme sequestration and crystallization into hemozoin within enlarged lysosomes of macrophages, thereby conferring heme tolerance to mammals.
Escherichia coli is surprisingly tolerant to chromatinization by archaeal histones, suggesting that histones can become established as ubiquitous chromatin proteins without interfering critically with some key DNA-templated processes.
Combined light and electron microscopy reveals a new function for Arp2/3-mediated actin assembly in nuclear envelope rupture, which leads to a separation of nuclear membranes and pores from the lamina.
While antimicrobial cocktails are highly effective for defence against pathogenic microbes, the innate immune response may instead employ highly specific peptidic antibiotics to combat certain natural enemies.
Thalidomide and its derivates induce degradation of many C2H2 zinc-finger transcription factors, including SALL4, providing insight into a long-standing mystery in modern pharmacology, and starting points for future drug development.
