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...

Muscle movements generate body heat. However, body heat can also be generated in another way: body fat contains a small number of brown adipose cells – special fat cells that can generate heat without muscle activity. They do this using a protein known as UCP1 that enables babies or hibernating animals to keep warm without shivering. A research team at the University of Veterinary Medicine (Vetmeduni Vienna) has found that a specific chemical compound, an aldehyde, can activate UCP1 under...

Researchers have created tiny protein tubes named after the Roman god Janus which may offer a new way to accurately channel drugs into the body’s cells. Using a process which they liken to molecular Lego, scientists from the University of Warwick and the University of Sydney have created what they have named ‘Janus nanotubes’ – very small tubes with two distinct faces. The study is published in the journal Nature Communications. They are named after the Roman god Janus who is...

Researchers Explain The Flagellar Synchronisation Of Swimming Algae

Max Planck Institute The beating of flagella is one of the basic principles of movement in the cellular cosmos. However, up to now, scientists were unsure as to how the movements of several of these small cellular appendages are synchronized. Dresden-based researchers from the Max Planck Institute of Molecular Cell Biology and Genetics and the MPI for the Physics of Complex Systems have now succeeded in demonstrating how the green alga Chlamydomonas synchronizes the movements of its two...

New research from the University of California, Davis, shows that the tiny proportion of a cell's DNA that is located outside the cell nucleus has a disproportionately large effect on a cell's metabolism. The work, with the model plant Arabidopsis, may have implications for future treatments for inherited diseases in humans. Plant and animal cells carry most of their genes on chromosomes in the nucleus, separated from the rest of the cell. However, they also contain a small number of genes...

Study reverses understanding of heart cell development Mitochondria are the power plants of cells, manufacturing chemical fuel so a cell can perform its many tasks. These cellular power plants also are well known for their role in ridding the body of old or damaged cells. Now, researchers at Washington University School of Medicine in St. Louis and the University of Padua-Dulbecco Telethon Institute in Italy have shown that mitochondria remarkably also orchestrate events that determine...

The outer membrane of bacteria contains many proteins that form tiny pores. They are important for absorbing nutrients and transmitting signals into the cell. The research group of Sebastian Hiller, Professor of Structural Biology at the Biozentrum, University of Basel, has now shown for the first time at atomic resolution, that these pore proteins are transported in an unstructured, constantly changing state to the outer bacterial membrane. This landmark study was recently published in the...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
