Effect of Environmental Epigenetics on Disease, Evolution

Aug. 3, 2015 — Environmental factors are having an underappreciated effect on the course of disease and evolution by prompting genetic mutations through epigenetics, a process by which genes are turned on and off ... read more

Protein Machines Make Fluctuating Flows Unconsciously

July 31, 2015 — Protein machines, regardless of their specific functions, can collectively induce fluctuating hydrodynamic flows and substantially enhance the diffusive motions of particles in the cell, an ... read more

July 27, 2015 — Researchers have discovered a long-overlooked process important for converting a long, string-like DNA molecule into a chromosome. This finding gives us a better understanding of the mechanism of how ... read more

July 24, 2015 — The DNA sequences of the 228 known butterfly species in the Iberian peninsula have been obtained by researchers who compared it to available data for Europe. Their study compiles 3500 genetic ... read more

How to Cut Worrying Levels of Arsenic in Rice That Is Eaten All Over the World

July 22, 2015 — Researchers have discovered a simple solution to worrying levels of arsenic in our rice. Rice is the only major crop grown under flooded conditions. It is this flooding that releases inorganic ... read more

July 22, 2015 — Scientists have published an overall map of how the cells in the human body communicate by systematically analyzing the relationship between ligands and ... read more

Yeast Cells Optimize Their Genomes in Response to the Environment

July 21, 2015 — Researchers have shown that yeast can modify their genomes to take advantage of an excess of calories in the environment and attain optimal ... read more

July 17, 2015 — A new approach to visualize glucose uptake activity in single living cells by light microscopy with minimum disturbance has been described by researchers. The team developed a new glucose analogue ... read more

July 16, 2015 — In response to an infection, the immune system refines its defensive proteins, called antibodies, to better target an invader. New research has revealed two mechanisms that favor the selection of B ... read more

July 16, 2015 — Iron regulatory proteins play an important role in the body's immune system. Proteins responsible for controlling levels of iron in the body also play an important role in combating infection, ... read more

Molecular Architecture of Cell Fission Processes Has Been Revealed

July 15, 2015 — Biological evolution has always gone hand in hand with cell evolution. The cells of eukaryotes, the most advanced branch in the evolutionary tree, are characterized by the fact that their nuclei are ... read more

Scientific Curiosity and Preparedness for Emerging Pathogen Outbreaks

July 14, 2015 — An essay reflects on a career path that started with the study of a somewhat obscure mouse virus mice and ended up at the frontline of the SARS and MERS coronavirus ... read more

Cell Size Regulation Mechanism Discovered

July 14, 2015 — Every cell in the human body has to be a particular size in order to function correctly. Scientists have now discovered a new mechanism that regulates cell ... read more

New Cell Division Mechanism Discovered

July 13, 2015 — Chromosomes play an active role in animal cell division, reports an international team of researchers. This occurs at a precise stage -- cytokinesis -- when the cell splits into two new daughter ... read more

Scientists Gain New Insights Into 'Antenna' of Human Cells

July 13, 2015 — The most comprehensive list yet of genes implicated in a group of common inherited diseases has been revealed by researchers. The research means that these disorders, known as ciliopathies, can be ... read more

Scientists Find Molecular Switch That Creates Long-Term Immunity

July 13, 2015 — Researchers have identified a protein responsible for preserving the antibody-producing cells that lead to long-term immunity after infection or ... read more

July 9, 2015 — Researchers set out to explain how B. subtilis times its sporulation decision with its cell-division cycle, a programmed series of events that cells normally follow to reproduce. What they found is ... read more

Modeling a Nervous Pathway Involved in Touch-Induced Behavior

July 9, 2015 — Many animals actively touch objects in their environment and respond to them by appropriate movement sequences. Biologists have captured the key properties of a wide variety of descending neurons ... read more

Cells Help Viruses During Cell Entry

July 9, 2015 — Adenoviruses cause numerous diseases, such as eye or respiratory infections, and they are widely used in gene therapy. Researchers have now discovered how these viruses penetrate the cells, a key ... read more

July 7, 2015 — The error-free distribution of genetic material during cell division is important for preventing the development of tumor cells. Researchers have uncovered a new important function of the human ... read more
