Ancestral molecule from bacteria-like cells may offer evolutionary insight on sexual reproduction

A study from Karolinska Institutet in Sweden, among others, presents the theory that egg-sperm fusion, a crucial feature of sexual reproduction in plants and animals, may have originated from an ancient form of genetic exchange that involved the fusion of bacteria-like microorganisms called archaea.

Cancer cells can gravitate toward certain mechanical 'sweet spot' environments, study finds

An international team of researchers led by University of Minnesota Twin Cities engineers have found that cancer cells can gravitate toward certain mechanical "sweet spot" environments, providing new insights into how cancer invades the body.

Study offers insight into cancer cell migration and opens new possibilities for stopping it

An international research group has investigated the mechanisms of cell migration and the impact of tissue rigidity on cell positioning and steering. The research sheds light on e.g. cancer cell migration and opens new possibilities for stopping and directing it.

Study calls for more conservation efforts to preserve adaptive DNA diversity of dolphin populations

The first widespread census of the genetic diversity of common dolphin (Delphinus delphis) populations living along 3000km of Australia's southern coastline has raised key pointers for future conservation efforts.

3D models of cranial endocasts help better understand brain evolution of lungfishes

The evolution of the brain and nervous system in animals has been wound back more than 400 million years, thanks to the examination of fossil remains of ancient lungfish providing a missing link in the emergence of land-living, four-legged animals on Earth.

Stinging nettle extract inhibits SARS-CoV-2 cell fusion

In a recent study posted to the bioRxiv* preprint server, researchers at Ghent University and KU Leuven, Belgium, demonstrated that Urtica dioica agglutinin (UDA), a monomeric lectin extracted from stinging nettle rhizomes, inhibited severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern (VOCs) cell to cell fusion.

Scientists capture a clear picture of the nuclear pore complex using X-rays

Your body is made of close to 100 trillion cells that keep you healthy and alive. Each cell has billions of parts of its own, all of them working in tandem to keep life's processes moving.

Researchers create a comprehensive map of how complex networks of genes function together

Using new technologies to study thousands of genes simultaneously within immune cells, researchers at Gladstone Institutes, UC San Francisco (UCSF), and Stanford School of Medicine have created the most detailed map yet of how complex networks of genes function together.

Newly-discovered historical information reveals that Mendel was decades ahead of his time

Gregor Mendel, the Moravian monk, was indeed "decades ahead of his time and truly deserves the title of 'founder of genetics.'" So concludes an international team of scientists as the 200th birthday of Mendel approaches on 20 July.

UT Southwestern researchers reveal the physical mechanism behind a neurological autoimmune disease

Using UT Southwestern's Cryo-Electron Microscopy Facility, researchers for the first time have captured images of an autoantibody bound to a nerve cell surface receptor, revealing the physical mechanism behind a neurological autoimmune disease.

Researchers unravel how epithelial cells become invasive and cancerous

Epithelial cells, which line the surfaces and organs of the body, can protect themselves against cancer by removing unhealthy or abnormal cells through a mechanism known as "apical extrusion," where the damaged cells are forcibly removed from the cell layer by the surrounding healthy cells.

Salk professor wins $2 million to gain better understanding of cassava genetics

Research Professor Todd Michael will receive nearly $2 million from the Bill & Melinda Gates Foundation to sequence the genomes of multiple lineages of the cassava plant, a large starchy root vegetable also known as yuca root consumed in more than 80 countries around the world.
