Researchers Reset Human Pluripotent Stem Cells to a Fully Pristine State

A newly published study details how scientists were able to successfully ‘reset’ human pluripotent stem cells to a fully pristine state. Researchers at EMBL-EBI have resolved a long-standing challenge in stem cell biology by successfully ‘resetting’ human pluripotent stem cells to a fully pristine state, at the point of their greatest developmental potential. The study, […]

Biologists Delay the Aging Process

Working with fruit flies, UCLA biologists showed that increasing the amount of the AMPK gene in fruit flies’ intestines increased their lifespans by about 30 percent. UCLA biologists have identified a gene that can slow the aging process throughout the entire body when activated remotely in key organ systems. Working with fruit flies, the life […]

Scientists Uncover How Beautiful Color Patterns Can Develop in Animals

Scientists at the Max Planck Institute have discovered how pigment cells arise and interact to form the ‘zebra’ pattern in zebrafish. The zebrafish, a small fresh water fish, owes its name to a striking pattern of blue stripes alternating with golden stripes. Three major pigment cell types, black cells, reflective silvery cells, and yellow cells […]

Evolution of Flies, Worms and Humans Share Patterns of Gene Expression

Several newly published studies reveal that flies, worms and humans share ancient patterns of gene expression. Although separated by hundreds of millions of years of evolution, flies, worms, and humans share ancient patterns of gene expression, according to a massive Yale-led analysis of genomic data. Two related studies led by scientists at Harvard and Stanford, […]

Living Organ Grown in a Lab

Scientists from the MRC Center for Regenerative Medicine at the University of Edinburgh have grown a fully functional organ from scratch in a living animal by transplanting cells that were originally created in a laboratory. The research could aid in the future development of ‘lab-grown’ replacement organs. Scientists have grown a fully functional organ from […]

Researchers Shed New Light on the Rings That Make Cell Division Possible

A team of scientists from Yale and Columbia universities has shed new light on the mechanics of the division of cells that makes life possible. Forming like a blown smoke ring does, a “contractile ring” similar to a tiny muscle pinches yeast cells in two. The division of cells makes life possible, but the actual […]

First Breakthrough about Life Under Antarctic Ice

Researchers from the WISSARD project have discovered an active ecosystem of microorganisms that live beneath the Antarctic ice sheet, converting ammonium and methane into the energy required for growth. Bozeman – The first breakthrough paper to come out of a massive U.S. expedition to one of Earth’s final frontiers shows that there’s life and an […]

Single Factor Can Reset the Immune System Back to What it Was 500 Million Years Ago

Scientists at the Max Planck Institute reveal that a single factor can reset the immune system of mice to a state likely similar to what it was 500 million years ago, when the first vertebrates emerged. Scientists at the Max Planck Institute of Immunobiology and Epigenetics (MPI-IE) in Freiburg re-activated expression of an ancient gene, […]

Scientists Discover New Immune System Weapon

Scientists have identified a previously unknown component of the immune system, discovering that bacterial virulence factors can not only be neutralized by antibodies, but they can also be directly destroyed by them. Max Planck researchers have discovered a completely new way in which the immune system recognizes pathogens. The aryl hydrocarbon receptor has long been […]

Researchers Produce a Depiction of the DNA Protein Complexes the Lambda Virus

After more than 50 years of research, biologists now have a picture of the molecular machines that allow the lambda virus to insert or remove DNA from the cells that it infects. Providence, Rhode Island (Brown University) — For half a century biologists have studied the way that the lambda virus parks DNA in the […]
