AbstractCoevolutionary cycling in allele frequencies due to negative frequency-dependent selection---sometimes referred to as Red Queen Dynamics---is a key potential outcome of host-parasite coevolution. While many theoretical studies have focused on understanding the consequences of coevolutionary cycling for the evolution of sex and recombination, little is known about the impact of oscillatory coevolutionary dynamics on the evolution of other life history traits.

Keir Starmer has returned from his whirlwind meeting with Donald Trump in Washington DC where the two discussed the hugely consequential matter of a possible Ukrainian peace agreement, a UK-US trade deal and the future of the Chagos Islands. And it seems as though the trip was a partial success for Starmer, with Trump cautiously backing the Chagos plan and suggesting the UK could avoid tariffs, although there was less clarity on security guarantees for Ukraine.

The yeast Saccharomyces cerevisiae ribosome contains four structural rRNAs and 78 proteins in its core makeup (1–3). These 78 proteins are translated from 59 duplicated gene pairs and 19 unique genes (4) that together total 137 ribosomal protein genes (RPGs). One hundred one of these genes require the removal of an intron by splicing to produce a mature messenger RNA (mRNA) (5).

Time to Reassess Systemic Fluoride Exposure, Again In 2015, the US Public Health Service lowered the recommended concentration of fluoride in drinking water, from a range of 0.7 to 1.2 mg/L to 0.7 mg/L, to reduce the risk of dental fluorosis while conserving its protective effect against dental caries.1 In that same year, the US National Toxicology Program (NTP), a federal program established to study the health effects of chemicals, began a systematic review and meta-analysis to assess the...

SFU professor Chelsey Geralda Armstrong’s research on beaked hazelnut DNA reveals Indigenous peoples in British Columbia cultivated and traded the plant 7,000 years ago, shaping the land sustainably. The study challenges colonial misconceptions of untouched landscapes and emphasizes Indigenous environmental expertise.
