Cells contain machinery that duplicates DNA into a new set that goes into a newly formed cell.
The Institut Pasteur has issued the following press release:
Surface-associated multicellular organisms are found throughout the biosphere and include common land plants, corals, lichens, bacterial biofilms and slime molds. Yet despite their prevalence, little is known about how they evolved.
Plants have microscopically small pores on the surface of their leaves, the stomata. With their help, they regulate the influx of carbon dioxide for photosynthesis. They also use the stomata to prevent the loss of too much water and withering away during drought.
Goodbye, bulky components and connectors: A team of scientists at the Max Planck Institute for Intelligent Systems in Germany and at the University of Colorado Boulder in the US has now found a new way to exploit the principles of spiders’ joints to create lightweight robots.
An international team of scientists has proposed a cross-disciplinary approach to biosecurity that may benefit both invasion biologists, who study the spread of non-native species, and epidemiologists, who study human infectious pathogens.
A team led by researchers at Baylor College of Medicine found that a screening method known as untargeted metabolomics profiling can improve the diagnostic rate for inborn errors of metabolism, a group of rare genetic conditions, by about seven-fold when compared to the traditional metabolic screening approach.
To grow and multiply efficiently, bacteria must coordinate cell division with chromosome segregation. Crucial to this process in the bacterium Bacillus subtilis is a protein called Nucleoid Occlusion Factor or Noc.
Hereditary information is passed from parent to offspring in the genetic code, DNA, and epigenetically through chemically induced modifications around the DNA. New research from the John Innes Centre has uncovered a mechanism which adjusts these modifications, altering the way information beyond the genetic code is passed down the generations.
The aging process of humans and other organisms can be hijacked by another species, like a virus, for the reproductive or survival advantage of the hijacker, while distorting the age of the host organism, according to a new study.
Physical bioenergetics, a new field of study, examines how much energy cells are using and how they apportion that energy.
Twice as much carbon is stored in the soil as it is in vegetation on land, but how it is accumulated and processed by microorganisms is not known. This is an important element for modeling carbon in climate science and soil fertility management.
A small study of young adults, using functional magnetic resonance imaging (fMRI), found that graphic warning labels affected their motivation to quit smoking more than text-only warning message labels.
Viewing high-quality images with optimal colors, even when looking at a tablet or smart phone in direct sunlight, may be possible when new research results are commercialized.
