Ancient Genome Duplications Fueled the Evolution of Complex Brains

New findings, published today (10 June) in Nature, help to answer the riddle of how vertebrates evolved the diverse array of brain cells that distinguishes them from other animals.

Ecotoxicology Study Finds Efficient Alternative for Native Chinese Fish Testing Models

Can tiny fish embryos help make chemical safety testing more ethical and efficient? A study published in Environmental Chemistry and Ecotoxicology provided new evidence to answer just that.

Tail Region of mRNAs Found to Act as Protein Chaperone

Proteins are how cells get work done. They carry out nearly every important cellular task, from ferrying messages to controlling which genes are turned on or off.

New Project Explores Virovory’s Potential to Combat Eutrophication

Toxic cyanobacterial blooms can close lakes, contaminate drinking water and pose risks to human health.

Mylpf Protein Identified as a Linchpin for Healthy Muscle Formation

University of Maine researchers have published new findings about how muscles form, why certain muscle diseases develop and why symptoms may not appear until years after muscle degeneration begins.

Four Reasons to Marvel at SA’s Coast this World Ocean Day

To celebrate World Ocean Day this 8 June, Adelaide University marine biologists Professor Sean Connell and Dr Dominic McAfee have shared four of their favourite facts about South Australia’s coastline.

Rising octopus numbers: UK study examines impacts on coasts and communities

A standout feature from the new report was the value of the survey of SCUBA divers and snorkelers. There were 120 responses in a relatively short period of time last year, and they provided an absolute wealth of information - along with some stunning photos.

Zebrafish Provide New Insights Into Microbiome Dynamics

A new advance in animal husbandry involving a popular aquarium fish should speed the pace of discovery in laboratory studies of host-microbe interactions, researchers report.

New Molecular Map Traces Human Disease Genes Back to LECA

A University of Texas at Austin-led team has reconstructed the most detailed map to date of the molecular machines that carried out the functions of life in an ancient ancestor that gave rise to all complex life on Earth, including us, shedding new light on genetic causes of human diseases.

Essential Keratin Guides Embryonic Cell Movement in Developing Zebrafish

Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they need to move together as a coherent tissue while modulating the driving forces behind their movement during early development. But what happens when keratin is missing?

How Minimal Medical Care Shifts Amazonian Villagers' Unique Gut Bacteria

Even minimal exposure to modern medicine can rapidly change the human microbiome. In a new study publishing May 20 in the Cell Press journal Cell Reports, researchers reveal that the gut microbes of remote Amazonian Indigenous communities began shifting toward patterns more commonly seen in urban, industrialized populations after only a few medical visits.

Physics Explains How Neural Tube Closure Occurs in Embryos

In about one out of every 1,000 pregnancies, the neural tube, a key nervous system structure, fails to close properly.

Researchers Map the Genetic History of Savanna and Forest Elephant Species

In the largest genomic mapping of Africa's elephants, an international team of researchers shows that elephant history is defined by the ability to move across large distances and exchange genes throughout the African continent. But as the elephants' living space is becoming increasingly patchy, the study documents the visible genetic consequences of isolation – and points to approaches that help to incorporate genomics into current and future elephant conservation.

Zebrafish Use Integrated Visual Signals to Move Up and Down in the Ocean

Using zebrafish, researchers from Osaka Metropolitan University (OMU) have identified the tegmentum region in the fish midbrain as the area where light input from both the fish's eyes and the pineal organ-the 'third eye'-is integrated.

Genetic Analysis Reveals Why Haploid Fish Embryos Fail to Survive

Naturally occurring haploids are predominantly documented in plants; the first report dates to 1923, when haploid individuals were identified in the Jimson Weed.

How Chromosomal Inversions Lock Beneficial Genes Together for Better Adaptation

When a species lives in two distinct types of habitats, individuals with traits better suited to each habitat will thrive and reproduce, naturally selecting descendants with those traits.

Deep-Sea Fish Reveal Novel Twilight Vision Cells

Researchers have identified a new type of visual cell in deep-sea fish larvae that challenges a century of knowledge about vertebrate visual systems.

New CRISPR Tool Actively Reverses Antibiotic Resistance Spread

Antibiotic resistance (AR) has steadily accelerated in recent years to become a global health crisis. As deadly bacteria evolve new ways to elude drug treatments for a variety of illnesses, a growing number of "superbugs" have emerged, ramping up estimates of more than 10 million worldwide deaths per year by 2050.

CRISPR Screen Reveals Genes Driving Human Muscle Development

Muscles make up nearly 40% of the human body and power every move we make, from a child’s first steps to recovery after injury. For some, however, muscle development goes awry, leading to weakness, delayed motor milestones or lifelong disabilities.
