Why elephants never forget but fleas have, well, the attention span of a flea

Researchers at the Complexity Science Hub and Santa Fe Institute have developed a model to calculate how quickly or slowly an organism should ideally learn in its surroundings. An organism’s ideal learning rate depends on the pace of environmental change and its life cycle, they say. Every day, we wake to a world that is […]

Alcohol consumption among non-human animals may not be as rare as previously thought, say ecologists

Anecdotes abound of wildlife behaving “drunk” after eating fermented fruits, but despite this, nonhuman consumption of ethanol has been assumed to be rare and accidental. Ecologists challenge this assumption in a review publishing October 30 in the Cell Press journal Trends in Ecology & Evolution. They argue that since ethanol is naturally present in nearly […]

12 new Oriental weevil species discovered using advanced imaging tools

Jake Lewis, an entomologist in the Environmental Science and Informatics Section at the Okinawa Institute of Science and Technology (OIST), is fascinated by weevils, a diverse group of beetles that includes many species with elephant trunk-like mouthparts (called a rostrum). Weevils provide various ecosystem services such as pollination and decomposition, but some species are serious […]

Move along, moose: Study reveals the ‘most Canadian’ animals

What is the “most Canadian” animal? Spoiler: it’s not the beaver, or the moose. Published today in the journal The Canadian Field-Naturalist, the study from a team of Simon Fraser University researchers ranks, for the first time ever, species of terrestrial vertebrates in Canada by their level of Canadian evolutionary distinctness: the amount of time […]

Human actions likely cause insect color change

New Zealand’s native stoneflies have changed colour in response to human-driven environmental changes, new research shows. Just published in the journal Science, the University of Otago study provides arguably the world’s most clear-cut case of animal evolution in response to change made by humans. Co-author Professor Jon Waters, of the Department of Zoology, says the […]

New tool enables a more complete and rapid decoding of the language of algal gene expression

A new method that research teams can use to measure and compare different forms of proteins and protein complexes helped reveal a previously unseen molecular signature of how algal genomes are controlled during the cell cycle. The publication, “pyMS-Vis, an open-source Python application for visualizing and investigating deconvoluted to-down mass spectrometric experiments: A histone proteoform […]

Researcher works to preserve the white shark in the Mediterranean Sea

The Mediterranean Sea is a paradise. Pristine waters and an incredible coastline spanning multiple continents that are renowned the world over. Below those picturesque, and sometimes crowded, waters swim a legendary creature facing a treacherous and uncertain future: the white shark. Francesco Ferretti, an assistant professor in the College of Natural Resources and Environment, is […]

Scientists recreate mouse from gene older than animal life

Published in Nature Communications, an international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular organism, with which we share a common ancestor that predates animals. This breakthrough reshapes our understanding of the genetic origins of stem […]

VU Researchers Publish Study on the Mechanism of CRISPR-Cas “Protein Scissors” in Molecular Cell

CRISPR-Cas systems help to protect bacteria from viruses. Several different types of CRISPR-Cas defense systems are found in bacteria, which differ in their composition and functions. Among them, the most studied proteins today are Cas9 and Cas12, also known as DNA or gene ‘scissors’, which have revolutionized the field of genome editing, enabling scientists to […]

Visualizing ER-phagy and ER architecture in vivo

ER-phagy is an evolutionarily conserved mechanism crucial for maintaining cellular homeostasis. However, significant gaps persist in our understanding of how ER-phagy and the ER network vary across cell subtypes, tissues, and organs. Furthermore, the pathophysiological relevance of ER-phagy remains poorly elucidated. Addressing these questions requires developing quantifiable methods to visualize ER-phagy and ER architecture in […]
