3D movie at ℠ultraresolution´ shows how cell´s machinery bends membrane inwards Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have combined the power of two kinds of microscope to produce a 3-dimensional movie of how cells ℠swallow´ nutrients and other molecules by engulfing them. The study, published today in Cell, is the first to follow changes in the shape of the cell´s membrane and track proteins thought to...

Finding biocompatible carriers that can get drugs to their targets in the body involves significant challenges.  Beyond practical concerns of manufacturing and loading these vehicles, the carriers must work effectively with the drug and be safe to consume. Vesicles, hollow capsules shaped like double-walled bubbles, are ideal candidates, as the body naturally produces similar structures to move chemicals from one place to another. Finding the right molecules to assemble into capsules,...

Blue Light Culprit In Red Tide Blooms
2012-02-24 04:57:10

Each year, phytoplankton blooms known as "red tides" kill millions of fish and other marine organisms and blanket vast areas of coastal water around the world. Though the precise causes of red tides remain a mystery, a team of researchers in the United States and Spain has solved one of the main riddles about these ecological disasters by uncovering the specific mechanism that triggers phytoplankton to release their powerful toxins into the environment. "Previous theories about how...

The many factors that contribute to how cells communicate and function at the most basic level are still not fully understood, but researchers at Baylor College of Medicine have uncovered a mechanism that helps explain how intracellular membranes fuse, and in the process, created a new physiological membrane fusion model. The findings appear in the current edition of the journal PLoS Biology. "Within our cells, we have communicating compartments called vesicles (a bubble-like membrane...

Opening up a new door in synthetic biology, a team of researchers has developed a microfluidic device that produces a continuous supply of tiny lipid spheres that are similar in many ways to a cell's outer membrane. "Cells are essentially small, complex bioreactors enclosed by phospholipid membranes," said Abraham Lee from the University of California, Irvine. "Effectively producing vesicles with lipid membranes that mimic those of natural cells is a valuable tool for fundamental biology...

Potent intracellular messengers implicated in cancer metastasis, blood clotting and inflammation Researchers at NYU Langone Medical Center have discovered a protein called TAT-5 that affects the production of extracellular vesicles, small sacs of membrane released from the surface of cells, capable of sending signals to other cells. When released extracellular vesicles can affect tumor spread, blood clotting and inflammation. Their discovery gives new insight into how extracellular...

Ascent Scientific, together with Freie Universität Berlin, The University of Newcastle and Children's Medical Research Institute today announced that they have entered into an exclusive licence, supply and distribution agreement for the clathrin inhibitors Pitstop 1TM and Pitstop 2TM for research. These novel compounds are the first rationally designed inhibitors of clathrin, and represent important tools for investigating essential cellular processes such as endocytosis. The agreement...

Dr. Katja Fälber and Professor Oliver Daumke, structural biologists at the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, together with researchers from Freie Universität (FU) Berlin, have determined the molecular structure of dynamin, a ℠wire-puller´ that mediates nutrient uptake into the cell. Since pathogens such as HIV can also enter the body´s cells in this way, understanding the underlying molecular mechanisms...

The crystal structure of the dynamin protein – one of the molecular machines that makes cells work – has been revealed, bringing insights into a class of molecules with a wide influence on health and disease. "It's a really cool structure," said Jodi Nunnari, professor and chair of molecular and cellular biology at UC Davis and senior author of the paper, to be published Sept. 18 in the journal Nature. "This is a really important class of molecules for regulating membrane...

Complex system transports essential cargoes such as proteins and membrane vesicles Every cell in the human body contains a complex system to transport essential cargoes such as proteins and membrane vesicles, from point A to point B. These tiny molecular motor proteins move at blistering speeds on miniature railways carrying components of the cell to their proper destinations. But just how cells construct these transport railways to fit precisely inside of confined spaces of the individual...

Phallusia nigra
2014-01-12 00:00:00

Phallusia nigra is a species of sea squirt (tunicate) found in tropical seas around the world. It is usually found in shallow waters attached to any hard substrate. It is a solitary animal rather than living in colonies. Although the native range of this animal is unknown, the tropical western Atlantic Ocean, the Red Sea and the Indian Ocean are possibilities. Like all ascidians, this species has a thick leathery envelope (tunic) containing cellulosic material. The tunic encloses a...

Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
