First detailed microscopy evidence of bacteria at the lower size limit of life


February 27th, 2015         by News -- ScienceDaily

Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The existence of ultra-small bacteria has been debated for two decades, but there hasn't been a comprehensive electron microscopy and DNA-based description of the microbes until now. The cells have an average volume of 0.009 cubic microns (one micron is one millionth of a meter). About 150 of these bacteria could fit inside an Escherichia coli cell and more than 150,000 cells could fit onto the tip of a human hair. Continue reading ...

Research of plain wren duets could help further understand fundamentals of conversation


February 27th, 2015         by News -- ScienceDaily

Known for their beautiful singing duets, plain wrens of Costa Rica perform precise phrase-by-phrase modifications to the duration between two consecutive phrases, achieving careful coordination as their songs unfold. A new study shows that these songbirds achieve precise coordination by adjusting the period between two consecutive phrases (inter-phrase intervals), depending on whether their song is answered, the phrase type used in the duet and the position of the inter-phrase interval within the duet.

New compounds protect nervous system from the structural damage characteristic of multiple sclerosis


February 27th, 2015         by News -- ScienceDaily

A newly characterized group of pharmacological compounds block both the inflammation and nerve cell damage seen in mouse models of multiple sclerosis, according to a study. Multiple sclerosis is a disease of the brain and spinal cord, where for unknown reasons, the body's immune system begins an inflammatory attack against myelin, the protective nerve coating that surrounds nerve fibers. Once myelin is stripped from these fibers, the nerve cells become highly susceptible to damage, which is believed to underlie their destruction, leading to the steady clinical decline seen in progressive forms of multiple sclerosis. Continue reading ...

How were fossil tracks made by Early Triassic swimming reptiles so well preserved?


February 27th, 2015         by News -- ScienceDaily

That swim tracks made by tetrapods occur in high numbers in deposits from the Early Triassic is well known. What is less clear is why the tracks are so abundant and well preserved. Paleontologists have now determined that a unique combination of factors in Early Triassic delta systems resulted in the production and unusually widespread preservation of the swim tracks: delayed ecologic recovery, depositional environments, and tetrapod swimming behavior.

Growth signal can influence cancer cells’ vulnerability to drugs, study suggests


February 27th, 2015         by News -- ScienceDaily

In theory, a tumor is an army of clones, made up of many copies of the original cancerous cell.
