Cell division is an intricately choreographed ballet of proteins and molecules that divide the cell. During mitosis, microtubule-organizing centers assemble the spindle fibers that separate the copying chromosomes of DNA. While scientists are familiar with MTOCs' existence and the role they play in cell division, their actual physical structure remains poorly understood. Researchers are now trying to decipher their molecular architecture.
Circadian clocks arose as an adaptation to dramatic swings in daylight hours and temperature caused by the Earth's rotation, but we still don't fully understand how they work. Scientists studying the circadian clock of blue-green colored cyanobacteria. The group discovered that how the proteins move hour by hour is central to cyanobacteria's circadian clock function.
A new study illuminates the biology that guides behavior across different stages of life in worms, and suggests how variations in specific neuromodulators in the developing nervous system may lead to occasional variations.
Preliminary research from a small pilot study carried out in Meru, in eastern Kenya, shows a link between chronic pain and consumption of glutamate, a common flavor enhancer found in Western and non-Western diets worldwide.
Sound waves generated by burbling lakes of lava atop some volcanoes point to greater odds of magmatic outbursts. This finding could provide advance warning to people who live near active volcanoes.
The findings highlight a rural-urban divide and show that ranchers' access to water was neither equal nor valued during the drought in Mexico's Baja California Sur state from 2006 to 2012.
A new blood test called the Tick-Borne Disease Serochip (TBD Serochip) promises to revolutionize the diagnosis of tick-borne disease by offering a single test to identify and distinguish between Borrelia burgdorferi, the pathogen responsible for Lyme disease, and seven other tick-borne pathogens.
