A fundamental new discovery about how nerve cells in the brain store and release tiny sacs filled with chemicals may radically alter the way scientists think about neurotransmission — the electrical signaling in the brain that enables everything from the way we move, to how we remember and sense the world. According to the scientists at the University of California, San Francisco (UCSF) who conducted the research, the discovery doesn´t change the players involved so much as it...

New studies illuminate brain's complex neurotransmission machinery, point to potential source of problems leading to neurodegenerative and psychiatric conditions Two studies featuring research from Weill Cornell Medical College have uncovered surprising details about the complex process that leads to the flow of neurotransmitters between brain neurons -- a dance of chemical messages so delicate that missteps often lead to neurological dysfunction. A recent Nature Neuroscience study led by Dr....

The research could lead to advanced therapies for patients with dry mouth University of Louisville researchers are one step closer to helping millions of people whose salivary glands no longer work because of disease or damage from treatment of diseases. The scientific finding of Douglas Darling, PhD, professor, Department of Oral Health and Rehabilitation, UofL School of Dentistry, and his team identified a protein sorting mechanism used by the salivary gland. The National Institutes of...

With every bodily movement"”from the blink of an eye to running a marathon"”nerve cells transmit signals to muscle cells. To do that, nerve cells rely on tiny molecular motors to transport chemical messengers (neurotransmitters) that excite muscles cells into action. It's a complex process, which scientists are still trying to understand. A new study by Syracuse University researchers has uncovered an important piece of the puzzle. The study, published in the April 22 issue of...

Research in the worm is shedding light on a protein associated with a number of different human cancers, and may point to a highly targeted way to treat them.University of Wisconsin-Madison scientists were studying a worm protein called TFG-1, which is present in many cell types but whose exact role had never been understood. The scientists discovered that the protein controls key aspects of the movement, or secretion, of growth factors out of cells."TFG-1 has never been implicated in the...

Discovery of inorganic, semipermeable clay vesicles indicates minerals could have played a key role in the origins of life A team of applied physicists at Harvard's School of Engineering and Applied Sciences (SEAS), Princeton, and Brandeis have demonstrated the formation of semipermeable vesicles from inorganic clay. The research, published online this week in the journal Soft Matter, shows that clay vesicles provide an ideal container for the compartmentalization of complex organic...

Frontotemporal dementia is caused by a breakdown of nerve cells in the frontal and temporal region of the brain (fronto-temporal lobe), which leads to, among other symptoms, a change in personality and behavior. The cause of some forms of frontotemporal dementia is a genetically determined reduction of a hormone-like growth factor, progranulin. Scientists around Dr. Anja Capell and Prof. Christian Haass have now shown that various drugs that are already on the market to treat malaria, angina...

The ability of some forms of plankton and bacteria to build an extra natural layer of nanoparticle-like armor has inspired chemists at the University of Warwick to devise a startlingly simple way to give drug bearing polymer vesicles (microscopic polymer based sacs of liquid) their own armored protection. The Warwick researchers have been able to decorate these hollow structures with a variety of nanoparticles opening a new strategy in the design of vehicles for drug release, for example by...

Understanding how lignin building blocks are transported could break down barriers to biofuel production One big challenge in converting plants to biofuels is that the very same molecules that keep plants standing up make it hard to break them down. Now scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are unraveling details of how plant cells' structural supports - their cell walls - are made, with the hope of finding ways to change their composition for more...

Reclaimed proteins enable the fusion of transmitter vesicles with the cell membrane Neurons communicate via chemical transmitters which they store in the bubble-like synaptic vesicles and release as required. To be able to react reliably to stimulation, neurons must have a certain number of "acutely releasable" vesicles. With the help of a new method, neuroscientists at the Max Planck Institute of Experimental Medicine in Göttingen have now discovered that neurons systematically recycle...

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...
