A Break in the Search for the Origin of Complex Life

A Break in the Search for the Origin of Complex Life
In Norse mythology, humans and our world were created by a pantheon of gods who lived in the realm of Asgard. As it turns out, these stories have a grain of truth to them.Thanks to a team of scientists led by Thijs Ettema, Asgard is now also the name of a large clan of microbes.…

U.S. Puts Bumblebee On The Endangered Species List For 1st Time

U.S. Puts Bumblebee On The Endangered Species List For 1st Time
The U.S. Fish and Wildlife Service has designated the rusty patched bumblebee an endangered species — the first such designation for a bumblebee and for a bee species in the continental U.S. The protected status, which goes into effect on Feb. 10, includes requirements for federal protections and the development of a recovery plan. It…

TSRI Scientists Discover Master Regulator of Cellular Aging

TSRI Scientists Discover Master Regulator of Cellular Aging
Scientists at The Scripps Research Institute (TSRI) have discovered a protein that fine-tunes the cellular clock involved in aging. This novel protein, named TZAP, binds the ends of chromosomes and determines how long telomeres, the segments of DNA that protect chromosome ends, can be. Understanding telomere length is crucial because telomeres set the lifespan of…

Promising new drug stops spread of melanoma by 90 percent

Promising new drug stops spread of melanoma by 90 percent
Michigan State University researchers have discovered that a chemical compound, and potential new drug, reduces the spread of melanoma cells by up to 90 percent. The human-made, small-molecule drug compound goes after a gene's ability to produce RNA molecules and certain proteins in melanoma tumors. This gene activity, or transcription process, causes the disease to…

All 2.3 Million Species Are Mapped into a Single Circle of Life

All 2.3 Million Species Are Mapped into a Single Circle of Life
Since Charles Darwin's day, biologists have depicted how new organisms evolve from old ones by adding branches to numerous trees that represent portions of the animal, plant and microbial kingdoms. Researchers from a dozen institutions recently completed a three-year effort to combine tens of thousands of trees into one diagram, most readable as a circle…

Protein disrupts infectious biofilms

Protein disrupts infectious biofilms
Many infectious pathogens are difficult to treat because they develop into biofilms, layers of metabolically active but slowly growing bacteria embedded in a protective layer of slime, which are inherently more resistant to antibiotics. Now, a group of researchers at Caltech and the University of Oxford have made progress in the fight against biofilms. Led…

Interpreting Large-Scale Phylogenetic Models of Mammal Class Diversification Based on Mitochondrial Biomarkers

Interpreting Large-Scale Phylogenetic Models of Mammal Class Diversification Based on Mitochondrial Biomarkers
Tommy Rodriguez Department of Research & Development, Pangaea Biosciences, Miami, FL, USA Email: trodriguez[@]pangaeabio.com Rodriguez, T. (2016). Interpreting Large- Scale Phylogenetic Models of Mammal Class Diversification Based on Mitochondrial Biomarkers. J Bioinfo Proteomics Rev 2(3): 1- 07. DOI: 10.15436/2381-0793.16.1181. Abstract This investigation reexamines mammal class diversification from a comparative phylogenetic perspective. By reconstructing a large-scale…

Biologists watch speciation in a laboratory flask

Biologists watch speciation in a laboratory flask
Biologists have discovered that the evolution of a new species can occur rapidly enough for them to observe the process in a simple laboratory flask. In a month-long experiment using a virus harmless to humans, biologists working at the University of California San Diego and at Michigan State University documented the evolution of a virus…

Endangered Australasian marsupials are ancient survivors of climate change

Endangered Australasian marsupials are ancient survivors of climate change
In a new paper, published in Scientific Reports, an international team of researchers has analysed fossils and DNA from living and recently extinct species to show that conservation sensitive Australasian marsupials are much older than previously thought. "We used bandicoots as a model to examine the radiation of marsupials relative to climate change through time.…
