A team led by a University of Miami researcher is creating the first map of protein interactions within neurons, in a live organism University of Miami biology professor Akira Chiba is leading a multidisciplinary team to develop the first systematic survey of protein interactions within brain cells. The team is aiming to reconstruct genome-wide in situ protein-protein interaction networks (isPIN) within the neurons of a multicellular organism. Preliminary data were presented at the...

[ Watch the Video ] A new method for visualizing mechanical forces on the surface of a cell, reported in Nature Methods, provides the first detailed view of those forces, as they occur in real-time. “Now we´re able to measure something that´s never been measured before: The force that one molecule applies to another molecule across the entire surface of a living cell, and as this cell moves and goes about its normal processes,” says Khalid Salaita, assistant...

The carbon footprint of humans will be reduced by four awards for plant and microbial research issued under a new joint U.S./Japanese program Four joint United States and Japanese research teams have been awarded funding totaling about $12 million (about Yen 960 million) to develop new environmentally-friendly techniques to increase the production of renewable biofuel and reduce pesticide use. These environmentally-friendly techniques will be based on studies of metabolites--chemical...

A new technique developed by researchers at RIKEN has clarified the location and dynamics of specific metabolites in a single cell of the alga Chara australis. The findings reveal that these metabolites are regulated and fluctuate under stress conditions, providing insight into previously-unknown functions of the vacuole in cellular processes. Metabolites, the intermediates and products of chemical reactions that sustain all living organisms, play a central role in cellular processes...

Molecules in their breath, sweat and skin have been used to detect humans in a simulation of a collapsed building, raising the prospect of portable sensors for use in real-life situations, such as the devastating aftermath of the 9/11 attacks and more recent disasters in New Zealand and Japan. Published today, Monday 12 September, in IOP Publishing's Journal of Breath Research, the study examined flumes of air to create a preliminary profile of molecules that could indicate human activity...

When It Comes To Speaking Out, Cells Wait Their Turn

  Revealing how cells communicate, Tel Aviv University research could lead to new cancer drugs and more Cell communication is essential for the development of any organism. Scientists know that cells have the power to "talk" to one another, sending signals through their membranes in order to "discuss" what kind of cell they will ultimately become – whether a neuron or a hair, bone, or muscle. And because cells continuously multiply, it's easy to imagine a cacophony of...

callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary.
