CT scanning and 3D modeling shed light on evolution of pelvic fins in shark embryos

Curtin University researchers have revealed how the pelvic fins of fish such as sharks and chimeras have evolved from their sudden appearance in the fossil record over 410 million years ago.

Octopuses' acuity may provide a critical link in understanding the evolution of complex life

Octopuses have captured the attention of scientists and the public with their remarkable intelligence, including the use of tools, engaging in creative play and problem-solving, and even escaping from aquariums.

Understanding the step-by-step development of E. coli resistance to drugs

Antibiotic resistance, which occurs when infection-causing bacteria evolve to the point where they are no longer affected by conventional antibiotics, is a worldwide concern.

The potential of cellular “glue” in regenerative medicine

Scientists at UC San Francisco have created molecules that function as “cellular glue,” enabling them to precisely control how cells adhere to one another. The discovery is a significant step toward regenerative medicine’s long-term goal of creating new tissues and organs.

3D imaging of shark embryos reveals evolution of pelvic fins

Curtin University researchers have revealed how the pelvic fins of fish such as sharks and chimaeras have evolved from their sudden appearance in the fossil record over 410 million years ago.

Stress hormones produced by salmon could be leading to increased infections

Fish farming is a crucial industry in Norway, and salmon is by far the most important species. So it's alarming that bacterial diseases are on the rise at the massive sea farms where salmon are raised.

Small fluorescent protein helps researchers to capture deeper, more precise biomedical images

Biomedical and genetic engineers at Duke University and the Albert Einstein College of Medicine have designed a small fluorescent protein that emits and absorbs light that penetrates deep into biological tissue.

Conservation policies tailored to individual populations could help adapt to the warming world

Human-released greenhouse gasses are causing the world to warm, and with that warming comes increasing stress for many of the planet's plants and animals.

Revealing the unappreciated role of POLQ in responding to DNA replication stress

Researchers at the Francis Crick Institute, in partnership with Artios, have discovered how an enzyme involved in DNA repair (POLQ) becomes critical to the survival of some tumors when the cancer cells lose the ability to employ a more frequent way of DNA repair.

Research could advance our understanding of evolution and the origins of cell motility

The origin of all biological movements, including walking, swimming, or flying, can be traced back to cellular movements; however, little is known about how cell motility arose in evolution.

Nitrogen metabolism adaptations allowed marine cyanobacteria to survive in the ocean

The UCO publishes a review of the nitrogen metabolism adaptations that allowed the most abundant photosynthetic organism on Earth, marine cyanobacteria, to survive in environments very poor in nutrients.

Acute infection disrupts the healthy balance between the good and bad gut microbes

Rutgers researchers examined the impact of COVID-19 on patients’ microbiomes, the group of microbes that live in and on the human body.

Gaining better insights into the origins of jaws by DNA sequence

At Uppsala University, a DNA sequence found in jawed vertebrates has been discovered and characterized by scientists. This includes sharks and humans, but it is absent in jawless vertebrates, like lampreys.

Resolving evolutionary origins of the platypus of fungi

A new study led by a research group from the University of Alberta has shown that nearly 600 apparently diverse fungi that never quite discovered a fit along the fungal family tree have been shown to have a general ancestor.

Fastest-evolved regions of the human genome diverged rapidly after split from chimpanzee ancestor

A team of Duke researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.

New effort to generate high quality reference genomes for 1,000 known species of euglenoids

The Euglena International Network (EIN) (https://euglenanetwork.org/), founded in 2020, is a global consortium of hundreds of scientists around the world with the collective goal of supporting euglenoid science through collaborative and integrative omics between academics and industry.

A gene’s function in embryonic development

An international study led by the medical school at the University of Bonn has discovered a gene that is crucial to the growth of the human embryo. Abnormalities of different organ systems may occur if it is changed.

First-ever pedigree provides insights for maximizing genetic diversity in aquarium-bred corals

Corals bred in public aquaria provide novel research opportunities and a healthy stock for outplanting into the wild, essential components of a thriving future for coral reef ecosystems, which support around 25% of all life in Earth's oceans.

Evolution of tree roots may have triggered ancient, global-scale extinction events

The evolution of tree roots may have triggered a series of mass extinctions that rocked the Earth's oceans during the Devonian Period over 300 million years ago, according to a study led by scientists at IUPUI, along with colleagues in the United Kingdom.

Researchers discover murderous survival strategy of yeast

Yeast is not the simple single-celled microorganism we once thought, but a competitive killer. When starved of glucose, yeast releases a toxin that will poison other microorganisms that have entered its surrounding habitat, even its own clones.
