A mammoth discovery: oldest DNA on record from million-year-old teeth
Researchers sequence the oldest DNA ever recovered, and the people bringing art and science together.In this episode:00:46 Million-year-old mammoth DNAThis week, researchers have smashed a long-standing record by sequencing a genome that's over a million years old. They achieved this feat by extracting DNA from permafrost-preserved mammoth teeth, using it to build-up a more detailed family tree for these ancient animals.Research Article: van der Valk et al.News: Million-year-old mammoth genomes shatter record for oldest ancient DNANews and Views: Million-year-old DNA provides a glimpse of mammoth evolution10:00 Research HighlightsA spacecraft catches a rare glimpse of a rock smashing into Jupiter, and the perilous state of sawfish populations.Research Highlight: Robotic eyes spy the flash of a meteor on JupiterResearch Highlight: Humans push a hulking fish with a chainsaw nose towards oblivion12:18 Putting art into science (and science into art)Art and science are sometimes considered disparate, but when brought together the results can be greater than the sum of their parts.

This article aims to introduce forensic practitioners to basic concepts in genetics and epigenetics so that they are able to engage with the relevant literature and understand the far-reaching implications for forensic practice. It is becoming increasingly useful for forensic practitioners to appreciate how life experiences are encoded into biology through epigenetics. This paper highlights the potential of genetic and epigenetic research to provide major contributions to real-world practice in the coming years. It provides a modern biopsychosocial perspective on harmful behaviour and helps deepen the understanding of o...

This article discusses ethical considerations and principles and propose use of the 4Es model and core communication skills to address ethical dilemmas in veterinary practice. It reviews literature defining ethical issues in practice and provides case examples to show the application of our proposed methods. The goal is to provide veterinary professionals with an approach they can use to frame and address their own ethical decisions.
One of the most impactful ways to create a dynamic team is to foster diversity and inclusivity within the workplace. Workplaces have become more heterogenous as advances in human, women, and civil rights group have spurred greater labor force participation by members of historically underrepresented groups. Studies have shown that leveraging diversity has important implications for the promotion of positive organization change through facilitation of individual and organization performance. Diverse clientele may be more comfortable and feel more welcome working with people in a diverse workplace.
