Salk Institute New results ease previous concerns that gene-editing techniques—used to develop therapies for genetic diseases—could add unwanted mutations to stem cells. The ability to switch out one gene for another in a line of living stem cells has only crossed from science fiction to reality within this decade. As with any new technology, it brings with it both promise—the hope of fixing disease-causing genes in humans, for example—as well as questions and safety concerns....

Neural Regeneration Research Researchers at the University of Birmingham, UK, led by Dr. Ben Scheven, Dr. Wendy Leadbeater and Ben Mead have discovered that stem cells isolated from the teeth, termed dental pulp stem cells (DPSC), can protect retinal ganglion cells (RGCs) from death following injury and promote regeneration of their axons along the optic nerve. RGC loss is the leading cause of blindness and can arise through traumatic injury or degenerative diseases such as glaucoma....

European Society of Human Reproduction and Embryology Oral contraceptive users have significantly lower measures of ovarian reserve than non-users A project in Denmark whose aim is to assess the reliability of preconceptional lifestyle and biological factors as predictors of fertility has found a pronounced effect of the contraceptive pill on markers used to assess "ovarian reserve", a predictor of future reproductive lifespan. Available evidence of whether the Pill has an effect on...

HSC Mesenchymal stem cells have become attractive tools for bioengineers, but some scientists haven’t given up on their regenerative potential Stem cell scientists had what first appeared to be an easy win for regenerative medicine when they discovered mesenchymal stem cells several decades ago. These cells, found in the bone marrow, can give rise to bone, fat, and muscle tissue, and have been used in hundreds of clinical trials for tissue repair. Unfortunately, the results of these...

The Rockefeller University About seven days after conception, something remarkable occurs in the clump of cells that will eventually become a new human being. They start to specialize. They take on characteristics that begin to hint at their ultimate fate as part of the skin, brain, muscle or any of the roughly 200 cell types that exist in people, and they start to form distinct layers. Although scientists have studied this process in animals, and have tried to coax human embryonic...

Rhithrogena germanica, known as the March brown mayfly in in the British Isle, is a species of mayfly that can be found throughout northern and central areas of Europe. Its range includes the River Tweed in England, Hesse in Germany, Denmark, Poland, and France. It was first described by Alfred Edwin Eaton, who studied a male specimen from the River Rhine. Rhithrogena germanica begins its lifecycle in the larval stage, as a water dwelling naiad that is typically found in fast flowing,...

Vase Tunicate, Ciona intestinalis
2014-01-12 00:00:00

The Vase Tunicate (Ciona intestinalis) is a species of sea squirt widely distributed in Northern European waters. It has also spread to other parts of the world, where it is considered invasive. It grows in dense aggregations on any floating or submerged substrate, especially on artificial structures like pilings, aquaculture gear, floats and boat hulls. It is found in the lower intertidal and subtidal zones. Sea squirts have been long recognized as being possibly the closest invertebrate...

The Orthoptera are an order of insects with incomplete metamorphosis, including the grasshoppers, crickets, locusts, and katydids. Many insects in this order produce sound (known as stridulation) by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. Their ears, located in the front legs, are interconnected in such a way that they are able to locate each other by sound. Characteristics Orthopterans have two pairs of wings - the...

The Ghost Shrimp, Pestarella tyrrhena is a species of thalassinidean crustacean that dwells in shallow, sandy tunnels of the ocean floor in the Mediterranean Sea and northern Atlantic Ocean. Initially, the crustacean derived its name from the Tyrrhenian Sea where it inhabited. The crustacean was called formerly Callianassa tyrrhena, but current common terminology for the species is Ghost Shrimp or Mud Shrimp. Fishermen in the Mediterranean have used it as bait for at least 200 years...
