Do people and monkeys see colors the same way?      (via sciencedaily.com)     Original source 

New findings in color vision research imply that humans can perceive a greater range of blue tones than monkeys do. Distinct connections found in the human retina may indicate recent evolutionary adaptations for sending enhanced color vision signals from the eye to the brain.

Scientists slow aging by engineering longevity in cells      (via sciencedaily.com)     Original source 

Researchers have developed a biosynthetic 'clock' that keeps cells from reaching normal levels of deterioration related to aging. They engineered a gene oscillator that switches between the two normal paths of aging, slowing cell degeneration and setting a record for life extension.

Information 'deleted' from the human genome may be what made us human      (via sciencedaily.com)     Original source 

What the human genome is lacking compared with the genomes of other primates might have been as crucial to the development of humankind as what has been added during our evolutionary history, according to a new study led by researchers at Yale and the Broad Institute of MIT and Harvard. The new findings, published April 28 in the journal Science, fill an important gap in what is known about historical changes to the human genome.

Study links 'stuck' stem cells to hair turning gray      (via sciencedaily.com)     Original source 

Certain stem cells have a unique ability to move between growth compartments in hair follicles, but get stuck as people age and so lose their ability to mature and maintain hair color, a new study shows.

Coastal species persist on high seas on floating plastic debris      (via sciencedaily.com)     Original source 

The high seas have been colonized by a surprising number of coastal marine invertebrate species, which can now survive and reproduce in the open ocean, contributing strongly to the floating community composition. Researchers found coastal species, representing diverse taxonomic groups and life history traits, in the eastern North Pacific Subtropical Gyre on over 70 percent of the plastic debris they examined. Further, the debris carried more coastal species than open ocean species.

Biologists determine the evolutionary age of individual cell types providing critical insights for animal development      (via sciencedaily.com)     Original source 

A research team has recently made a significant discovery about the evolutionary age of different type of cells in a small animal called Caenorhabditis elegans (C. elegans). By using single-cell transcriptomic data and refined phylostratigraphy, the team determines the transcriptomic age of individual cells, which means they are able to estimate the evolutionary origin of different cells based on the age of the genes expressed in the cells.

Increased droughts are disrupting carbon-capturing soil microbes, concerning ecologists      (via sciencedaily.com)     Original source 

Soil stores more carbon than plants and the atmosphere combined, and soil microbes are largely responsible for putting it there. However, the increasing frequency and severity of drought, such as those that have been impacting California, could disrupt this delicate ecosystem. Microbial ecologists warn that soil health and future greenhouse gas levels could be impacted if soil microbes adapt to drought faster than plants do.

Genes are read faster and more sloppily in old age      (via sciencedaily.com)     Original source 

Scientists have demonstrated the following findings which apply across the animal kingdom: with increasing age, the transcriptional elongation speed of genes increases, whereby the quality of the gene products suffers. With dietary restrictions, these processes could be reversed.
