Reproductive medicine

Since ancient times, humans have been trying to exercise control over their reproductive decisions, whether to avoid undesired pregnancy or to improve their chances of conceiving. In addition, the risks of pregnancy and childbirth have always been a major challenge.

nature Magazine – April 13, 2023 issue: Octopuses use chemotactile receptors (CRs) in the suckers on their arms to ‘taste by touch’ as they explore their sea-floor environment. These proteins evolved from neurotransmitter receptors to allow octopuses to detect poorly soluble natural products on contact.

Transforming the understanding of brain immunity

Our understanding of how the brain and immune system interact has changed substantially over the past years and decades. Initially, the brain was thought to be immune privileged and isolated from the rest of the body.

nature Magazine – April 6, 2023 issue: In 1947, Isaac Berenblum proposed that the development of cancer was a two-stage process: the first step introduces mutations into healthy cells, the second then promotes tumour growth through tissue inflammation. In this week’s issue, Charles Swanton and his colleagues investigate the role of particulate matter in prompting the development of non-small-cell lung cancers and find that cancer initiation in response to pollution conforms to Berenblum’s model.

Science Magazine – March 31, 2023 issue: A new analysis shows that Great Plains tribes acquired horses much earlier than some historians had thought, consistent with Indigenous descriptions of a long and enduring partnership with the horse. This petroglyph, from the Tolar site in southern Wyoming, probably dates from soon after the modern horse became widespread in North America in the early 17th century.

Straight from the heart: Mysterious lipids may predict cardiac problems better than cholesterol

Conceptual illustration: a giant heart opens up on a hinge to reveal several gauges. Three of them, labeled HDL, LDL, and ApoB, display low levels. One, labeled Ceramides, displays high levels and is vibrating and letting off steam. Three tiny scientists stand at the foot of the heart, and one shines a flashlight on the Ceramides gauge.

Drug developers are now trying to target ceramides, which appear to contribute to a range of metabolic disorders

nature Magazine – March 30, 2023 issue: Medieval people on the Swahili coast of East Africa were among the first sub-Saharan people to practise Islam. David Reich, Chapurukha Kusimba and colleagues sequenced DNA from 80 individuals buried in six medieval and early modern coastal Swahili stone towns, dating between 1250 and 1800. Their analysis shows that African women and Asian men began mixing along the East African coast before the year 1000, and that the earliest Asian migrants were of largely Persian origin.
