Persistence of Ancestral KhoeSan Mitochondrial Patterns in Contemporary South African Populations

Annals of Human Genetics, EarlyView.
Abstract Introduction Southern Africa has been inhabited by hunter‐gatherers for at least 20,000 years and has received diverse immigration flows in the last 2000 years. The original inhabitants have interacted with the pastoralist migrants from Eastern Africa (∼2000 ybp), followed by the southern Bantu migration arriving some 1000 ybp, and more ...

“Beads-on-a-string” Star Formation Tied to One of the Most Powerful Active Galactic Nucleus Outbursts Observed in a Cool-core Galaxy Cluster

The Astrophysical Journal
With two central galaxies engaged in a major merger and a remarkable chain of 19 young stellar superclusters wound around them in projection, the galaxy cluster SDSS J1531+3414 ( z = 0.335) offers an excellent laboratory to study the interplay between ...

Has Politics Become More Professional? Career and Legislative Professionalisation in the Australian Parliament Since 1950

Australian Journal of Politics &History, EarlyView.
“Professional politicians” have been lamented for their perceived negative impact on representative democracy. However, the concept of “political professionalisation” is deployed inconsistently, making these claims difficult to assess. This article develops a framework to measure professionalisation across two dimensions: career professionalisation ...

Gravitational lensing reveals cool gas within 10-20 kpc around a quiescent galaxy

Communications Physics
While quiescent galaxies have comparable amounts of cool gas in their outer circumgalactic medium (CGM) compared to star-forming galaxies, they have significantly less interstellar gas.

Relevance of ecological momentary assessment for medication adherence in clinical settings: A precision psychiatry approach

British Journal of Clinical Psychology, EarlyView.
Abstract Background Medication non‐adherence is a leading cause of treatment failure in psychiatric populations. However, current studies highlight the lack of methodological guidance on medication assessments. Ecological Momentary Assessment (EMA), using smartphone‐based evaluations, shows promise for real‐time monitoring in everyday settings.

The Leakage of Lyman-continuum Photons from a Major Merger at z ∼ 1

The Astrophysical Journal
We report the detection of Lyman-continuum (LyC) photons from a massive interacting system at z = 1.097 in the Hubble Ultra Deep Field. The LyC detection is made in the far-ultraviolet F154W band of the UVIT telescope on board AstroSat.

Computers and chess masters: The role of AI in transforming elite human performance

British Journal of Psychology, EarlyView.
Abstract Advances in Artificial Intelligence (AI) have made significant strides in recent years, often supplementing rather than replacing human performance. The extent of their assistance at the highest levels of human performance remains unclear. We analyse over 11.6 million decisions of elite chess players, a domain commonly used as a testbed for AI

Antibiotic‐induced decrease of bacterial load in guinea pig intestine reduces α2‐adrenoceptor expression and activity in peristaltic motor inhibition

British Journal of Pharmacology, EarlyView.
Background and Purpose The use of analgosedatives in critically ill patients carries the risk of impairing gastrointestinal (GI) propulsion and could thereby lead to sepsis. The gut microbiota can influence GI motility, but whether GI microbial dysbiosis modifies GI peristalsis impairment by analgosedative drugs has not yet been analysed. This question
