Scientists Reveal Six Changing Faces of Pneumococcus Infection

An international team of experts has revealed a genetic switch that controls pneumococcus infection and allows the bacterium to randomly change its characteristics into six alternative states. This research could pave the way to improved vaccines. Every ten seconds a human being dies from Streptococcus pneumoniae infection, also known as pneumococcus, making it a leading […]

Salk Institute Discovers an On Off Switch for Aging Cells

Researchers at the Salk Institute for Biological Studies have discovered an on-and-off “switch” in cells that may hold the key to healthy aging. In our bodies, newly divided cells constantly replenish lungs, skin, liver and other organs. However, most human cells cannot divide indefinitely–with each division, a cellular timekeeper at the ends of chromosomes shortens. […]

Study Shows Deadly Violence a Natural Tendency in Chimps

Using data collected from 18 chimpanzee research sites, a newly published study shows that chimps engage in violent and sometimes lethal behavior regardless of human effects on local ecology. For decades, scientists studying chimpanzees in the wild have noted the ways our closest relatives are similar to humans — they form tightly knit social groups, […]

Eye of Zebrafish Larva Distinguishes Between Prey and Predator

A new study from the Max Planck Institute for Medical Research reveals how the eye of a zebrafish larva can already distinguish between prey and predator. Red or green? Small or large? Fast or slow? Humans and animals rely on their visual organs to classify objects in their environment. Decisions about how we best respond […]

Genetic Tug of War Explains Autism and Schizophrenia

A new study from Yale University shows that bigger babies do have increased risk of autism, while smaller babies are more likely to develop schizophrenia. The size of babies and even human behavior may be shaped during early fetal development by a molecular tug of war between paternal and maternal genes, according to an emerging […]

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 […]
