Circumventing evolution in cell factories can pave the way for commercializing new biobased chemicals to large-scale.
Duplicate copies of a gene shared by male and female fruit flies have evolved to resolve competing demands between the sexes. New genetic analysis by researchers at the University of Chicago describes how these copies have evolved separate male- and female-specific functions that are crucial to reproduction and fertility.
Adult male mice lacking a gene linked to intellectual disability have trouble completing and remembering mazes, with no changes in social or repetitive behavior, according to new research published in JNeurosci. This animal model provides a new way to study the role of this gene in learning and memory and provides a rodent model of pure intellectual disability.
The formation of self-organizing molecular patterns in cells is a critical component of many biological processes. Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich have proposed a new theory to explain how such patterns emerge in complex natural systems.
Researchers who've gotten the first look at a deep-sea 'dumbo' octopod hatchling report in Current Biology on Feb. 19 that the young octopods look and act much like adults from the moment they emerge from an egg capsule. Dumbo octopods are so named because their fins resemble Dumbo the elephant's ears.
In an effort to create a power source for future implantable technologies, a team of researchers developed an electric eel-inspired device that produced 110 volts from gels filled with water, called hydrogels. Their results show potential for a soft power source to draw on a biological system's chemical energy. Anirvan Guha will present the research during the 62nd Biophysical Society Annual Meeting, Feb. 17-21.
The Great Lakes Bioenergy Research Center (GLBRC), led by the University of Wisconsin-Madison, recently embarked on a new mission: to develop sustainable alternatives to transportation fuels and products currently derived from petroleum.
Honeybees gathering nectar inspired an algorithm that eased the burden of host servers handling unpredictable traffic by about 25 percent. Nature can inspire some great engineering, but it can also lead to some flops. Take slime mold: Standard algorithms beat it hands down to model connectivity. AAAS annual meeting presentation by systems researcher Craig Tovey.
Phospholipids are water insoluble "building blocks" that define the membrane barrier surrounding cells and provide the structural scaffold and environment where membrane proteins reside. During the 62nd Biophysical Society Annual Meeting, held Feb. 17-21, William Dowhan from the University of Texas-Houston McGovern Medical School will present his group's work exploring how the membrane protein phospholipid environment determines its structure and function.
Protein systems make up the complex signaling pathways that control whether a cell divides or, in some cases, metastasizes. Ras proteins have long been the focus of cancer research because of their role as 'on/off switch' signaling pathways that control cell division and failure to die like healthy cells do. Now, a team of researchers has been able to study precisely how Ras proteins interact with cell membrane surfaces.
