Explorations in the Dinaledi Subsystem of the Rising Star cave system have yielded some of the earliest evidence of a mortuary practice in hominins. Because the evidence is attributable to the small-brained , these analyses call into question several assumptions about behavioral and cognitive evolution in Pleistocene hominins. The evidence from the Dinaledi Subsystem, and at other locations across the Rising Star cave system may widen the phylogenetic breadth of mortuary, and possibly funerary, behaviors.

In two areas within the Hill Antechamber and the Dinaledi Chamber, this work uncovered concentrations of abundant fossils including articulated, matrix-supported skeletal regions consistent with rapid covering by sediment prior to the decomposition of soft tissue. We additionally re-examine the spatial positioning of skeletal material and associated sediments within the Puzzle Box area, from which abundant remains representing a minimum of six individuals were recovered in 2013 and 2014.

Such intentional designs, which are widely interpreted as signifying, recording, and transmitting information in a durable manner, were once considered exclusive to Late Pleistocene . Here we present observations of what appear to be engraved abstract patterns and shapes within the Dinaledi Subsystem of the Rising Star cave system in South Africa, incised into the dolomitic limestone walls of the cave.

He claimed that the university, through diversity, equity, and inclusion (DEI) policies, was forcing his department to consider applicants it wouldn't otherwise and, in the process, ruining science. He also insisted that there is no racial or gender bias in science.

Science, both teaching and doing, is under attack. The recent US presidential election of a person and platform with anti-science bias exemplifies this. The study of climate processes and patterns and the role of human activities in these phenomena are at the heart of multiple global crises, and yet the scientific results, and the scientists presenting them, are attacked constantly.
View Article and Find Full Text PDFAny scientist knows that to be a good scientist, they must conduct thoughtful research; generate high-quality, verifiable results and analyses; and get them into circulation in the scientific community. However, what often goes underappreciated is that this good science will likely remain ignored by most of the world if one doesn't find a way to get it out beyond the scientific community. Unfortunately, when it comes to making our science accessible, we scientists all too often fall short.

This paper explores the persistence of 'race as biology' in medical research via examining select citational practices that have perpetuated this problematic concept. Citations serve as a cornerstone in scientific literature, signifying reliability and expert affirmation.

The dynamics of urban environments can result in novel injuries and mortalities for these animals. However, these negative impacts can be mitigated through planning, and onsite veterinary care like that provided by the Ubud Monkey Forest in Bali, Indonesia.

The implications of human-produced environmental harms to global health are complex just as are their causes.

This research includes inference of human demographic history, understanding the genetic architecture of traits, and predicting disease risk. Researchers are not just structuring an intellectual inquiry when using genetic ancestry, they are also creating analytical frameworks with broader societal ramifications.

In 2023, recognizing that the long-tailed macaque is threatened by multiple factors: (1) declining native habitats across Southeast Asia; (2) overutilization for scientific, commercial, and recreational purposes; (3) inadequate regulatory mechanisms; and (4) culling due to human-macaque conflicts, a petition for rulemaking was submitted to the United States Fish and Wildlife Service to add the species to the US Endangered Species Act, the nation's most effective law to protect at risk species. The long-tailed macaque remains unprotected across much of its geographical range despite the documented continual decline of the species and related sub-species and the recent IUCN reassessment.

American higher education is one of the places where racism has been, and still is, well documented again and again and again. Not unexpectedly, six of the nine justices on the US Supreme Court recently chose to disregard these facts and argue for a "race neutral" approach in college admissions.

Heritability is not a measure of the relative contribution of nature nurture, nor is it the phenotypic variance explained by or because of genetic variance. Heritability is a correlative value. The evolutionary and developmental processes associated with human culture challenge the use of "heritability" for understanding human behavior.

Primates inhabit a wide range of habitats and play critical roles in sustaining healthy ecosystems that benefit human and nonhuman communities. Approximately 68% of primate species are threatened with extinction because of global pressures to convert their habitats for agricultural production and the extraction of natural resources.
