Our cells breathe and digest, as does the organism as a whole. They indeed use oxygen to draw the energy contained in the nutrients they ingest, before discarding the waste, as carbon dioxide and water. Glucose is a preferred nutrient for the cells. Its digestion occurs in the cytoplasm, in the absence of oxygen, and leads to the formation of pyruvate and a small amount of energy. Pyruvate is then carried into mitochondria, the cell's power plants, for a complete burning, thus providing a...

St. Jude Children's Research Hospital discovery that a protein vital for cell survival and immune balance has another form with a different function could yield additional cancer treatment strategy Research led by St. Jude Children's Research Hospital investigators suggests that safeguarding cell survival and maintaining a balanced immune system is just the start of the myeloid cell leukemia sequence 1 (MCL1) protein's work. Nearly 20 years after MCL1 was discovered, scientists have...

Findings offer new insights into neurologic development and regenerative therapies for neurologic disease Researchers at Columbia University Medical Center (CUMC) have identified a molecular pathway that controls the retention and release of the brain's stem cells. The discovery offers new insights into normal and abnormal neurologic development and could eventually lead to regenerative therapies for neurologic disease and injury. The findings, from a collaborative effort of the...

Researchers at the University of Liverpool have resolved the debate over the mechanisms involved in the shut-down process during cell division in the body. Research findings, published in the journal PNAS, may contribute to future studies on how scientists could manipulate this shut-down process to ensure that viruses and other pathogens do not enter the cells of the body and cause harm. Previous research has shown that when cells divide, they cannot perform any other task apart from...

The hair cells of the inner ear have a previously unknown "root" extension that may allow them to communicate with nerve cells and the brain to regulate sensitivity to sound vibrations and head position, researchers at the University of Illinois at Chicago College of Medicine have discovered. Their finding is reported online in advance of print in the Proceedings of the National Academy of Sciences. The hair-like structures, called stereocilia, are fairly rigid and are interlinked at their...

(Ivanhoe Newswire)-- Yale researchers have discovered how megakaryocytes or giant blood cells that produce wound healing platelets grow 10 or more times bigger than other blood cells and how they may cause a form of leukemia. "A failure of these cells to grow might be an initial trigger for megakaryoblastic leukemias," Diane Krause, senior researcher for the Yale Cancer Center, professor of laboratory medicine, cell biology, and pathology and associate director of the Yale Stem Cell...

Finding promises to streamline creation of therapeutic cells Despite the promise associated with the therapeutic use of human stem cells, a complete understanding of the mechanisms that control the fundamental question of whether a stem cell becomes a specific cell type within the body or remains a stem cell has–until now–eluded scientists. A University of Georgia study published in the March 2 edition of the journal Cell Stem Cell, however, creates the first ever blueprint...

Working in the emerging field of systems biology, UT Southwestern Medical Center researchers mathematically predicted how bacteria that cause food poisoning hijack a cell's sense of direction and then confirmed those predictions in living cells. The study proposed a new model to explain how mammalian cells establish the sense of direction necessary to move, as well as the mechanism that a disease-causing form of E. coli bacteria employ to hijack that ability. Cells need to orient...

In recent years, a number of controversial claims have been made about the female mammal's egg supply — that it is renewed over her adult lifetime (as opposed to the conventional understanding that she is born with all of her eggs), and that the source of these eggs is stem cells that originate in the bone marrow. Now, Weizmann Institute scientists have disproved one of those claims and pointed in new directions toward resolving the other. Their findings, based on an original method for...

Cell is a peer-reviewed scientific journal founded by Benjamin Lewin in January 1974 with the sponsorship of MIT Press. Lewin bought the rights to the journal in 1986 and published it under his own publishing arm Cell Press. Cell Press was sold to Elsevier in 1999, which currently publishes Cell twice monthly. Cell Press publishes several biomedical journals, including Cell, Neuron, Immunity, Molecular Cell, Developmental Cell, Cancer Cell, Current Biology, Structure, Chemistry &...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
