SEATTLE, May 15, 2014 /PRNewswire-USNewswire/ -- Known for its advocacy of intelligent design, Discovery Institute has released The Workhorse of the Cell: Kinesin, a dramatic new three-minute video revealing what could be the most visually stunning molecular machines in cells, called kinesins. The animation provides a new presentation of evidence for intelligent design at the cellular level. "It's one thing to tell someone, 'Hey, kinesins are key transport proteins within the cell.'...

Tokyo, Nov 25, 2013 - (ACN Newswire) - Researchers at Waseda University in Japan have for the first time directly observed the "molecular motor", called Xkid, that plays a critical role in facilitating the proper alignment of chromosomes during cell division. Their findings are expected to contribute greatly to elucidating the molecular mechanisms of chromosome segregation, a key aspect of the development of certain medical disorders including cancer and birth defects.A human being begins as...

[ Watch The Video: Nanotrain Transport System ] University of Oxford Tiny self-assembling transport networks, powered by nano-scale motors and controlled by DNA, have been developed by scientists at Oxford University and Warwick University. The system can construct its own network of tracks spanning tens of micrometres in length, transport cargo across the network and even dismantle the tracks. The work is published in Nature Nanotechnology and was supported by the Engineering...

Just like people, some proteins have characteristic ways of "walking," which (also like human gaits) are not so easy to describe. But now scientists have discovered the unique "drunken sailor" gait of dynein, a protein that is critical for the function of every cell in the body and whose malfunction has been associated with neurodegenerative disorders such as Lou Gehrig's disease and Parkinson's disease. The research, which was led by Samara Reck-Peterson of Harvard Medical School and...

How a molecular traffic jam impacts cell division Interdisciplinary research between biology and physics aims to understand the cell and how it organizes internally. The mechanisms inside the cell are very complicated. LMU biophysicist Professor Erwin Frey, who is also a member of the Cluster of Excellence “Nanosystems Initiative Munich” (NIM) is working with his group on one particular issue involved in the cell´s life. The professor for statistical and biological physics...

The transport system inside living cells is a well-oiled machine with tiny protein motors hauling chromosomes, neurotransmitters and other vital cargo around the cell. These molecular motors are responsible for a variety of critical transport jobs, but they are not always on the go. They can put themselves into "energy save mode" to conserve cellular fuel and, as a consequence, control what gets moved around the cell, and when. A new study by Carnegie Mellon University biochemists, published...

Researchers at the University of California, San Diego School of Medicine have identified the motors that move non-infectious prion proteins (PrPC) "“ found within many mammalian cells "“ up and down long, neuronal transport pathways. Identifying normal movement mechanisms of PrPC may help researchers understand the spread of infectious prions within and between neurons to reach the brain, and aid in development of therapies to halt the transport. Their study is published in the...

Rice University bioengineers measure pulling power of hitched pairs of protein motors A new study by Rice University bioengineers finds that the workhorse proteins that move cargo inside living cells behave like prima donnas. The protein, called kinesin, is a two-legged molecular machine. Rice's scientists invented tools that could measure the pulling power of kinesin both singly and in pairs, and they report this week in Biophysical Journal that kinesins don't work well together -- in...

Findings shed light on brain malformation that kills infants A University of Utah researcher helped discover how a "wimpy" protein motor works with two other proteins to gain the strength necessary to move nerve cells and components inside them. The findings shed light on brain development and provide clues to a rare brain disorder that often kills babies within months of birth. "It's like the 'Transformers' films: You start with this puny little car and it becomes a big robot capable of...

Breakthrough reveals that unleashing the power within requires another critical element for life: Water Researchers at the Louisiana State University Health Sciences Center have figured out how ATP is broken down in cells, providing for the first time a clear picture of the key reaction that allows cells in all living things to function and flourish. Discovered some 80 years ago, adenosine triphosphate is said to be second in biological importance only to DNA. Each cell in the human body...


Word of the Day
jument
  • A beast of burden; also, a beast in general.
'Jument' ultimately comes from the Latin 'jugum,' yoke.
