The cell (from Latin cella, meaning "small room"[1]) is the basic structural, functional, and biological unit of all known living organisms. Cells are the smallest unit of life that can replicate independently, and are often called the "building blocks of life". The study of cells is called cell biology. Cells consist of a protoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.[2] Organisms can be classified as unicellular (consisting of a single cell; including most bacteria) or multicellular (including plants and animals). While the number of cells in plants and animals varies from species to species, humans contain about 100 trillion (1014) cells.[3] Most plant and animal cells are visible only under the microscope, with dimensions between 1 and 100micrometres.[4] The cell was discovered by Robert Hooke in 1665, who named the biological unit for its resemblance to cells inhabited by Christian monks in a monastery.[5][6] The cell theory, first developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that all cells come from preexisting cells, that vital functions of an organism occur within cells, and that all cells contain the hereditary … Continue reading →

ANN ARBOR--Whether you're baking bread or building an organism, the key to success is consistently adding ingredients in the correct order and in the right amounts, according to a new genetic study by University of Michigan researchers. Using the baker's yeast Saccharomyces cerevisiae, Patricia Wittkopp and her colleagues developed a novel way to disentangle the effects of random genetic mutations and natural selection on the evolution of gene expression. Their findings are scheduled for online publication in the journal Nature on March 16. "These results tell us that the effects of mutations available for natural selection to act on can play a large role in how an organism evolves. The approach we developed allows us to test what those influences are and to better understand how evolution works," said Wittkopp, an associate professor in the U-M Department of Ecology and Evolutionary Biology and in the Department of Molecular, Cellular and Developmental Biology. The first authors of the Nature paper are EEB graduate student Brian Metzger and former MCDB graduate student David Yuan. In their study, the U-M researchers used the TDH3 gene, which helps baker's yeast cells convert sugar into energy used for growth. To understand how different genetic mutations … Continue reading →

BETHESDA, MD - Nearly 1,000 scientists from 35 countries will attend the 28th Fungal Genetics Conference organized by the Genetics Society of America (GSA), March 17-22, 2015, at the Asilomar Conference Grounds in Pacific Grove, CA. The conference will feature approximately 900 presentations (including over 200 talks) of cutting-edge fungal genetics research - with a focus on filamentous fungi - on topics including genomics, gene regulation, cell biology and development, evolutionary biology, fungal-host interactions and biotechnology. Professor Michael J. Hynes from the University of Melbourne will present the Perkins/Metzenberg Lecture on Saturday, March 21 at 5:45 pm, just prior to the closing conference banquet. This lecture is given at each Fungal Genetics Conference by a leader in fungal genetics research; it often includes an historical and thought-provoking perspective as well as an outlook on the future of the field. For more information on the conference program, including the timing of plenary sessions - each of which ends with a Chair's Choice Talk presenting high impact studies nominated by the scientific community - please see the schedule of events. Numerous species of fungi are instrumental model organisms for the study of biology - particularly of genetics and related phenomena including heredity, … Continue reading →

A new approach for studying the behaviour of proteins in living cells has been developed by an interdisciplinary team of biologists and physicists in the Cell Biology and Biophysics Unit, the Ellenberg Laboratory and the Advanced Light Microscopy Facility Heidelberg, 16 March 2015 - A new approach for studying the behaviour of proteins in living cells has been developed by an interdisciplinary team of biologists and physicists in the Cell Biology and Biophysics Unit, the Ellenberg Laboratory and the Advanced Light Microscopy Facility at the European Molecular Biology Laboratory in Heidelberg. Described in a new study, published today in Nature Biotechnology, the approach allows scientists for the first time to follow the protein networks that drive a biological process in real time. Which proteins interact with each other and where they meet within cells is of huge interest to scientists because it reveals the state and activity of the molecular machinery that drives the most fundamental functions of life such as the ability of cells to divide. The new technique will also be useful for scientists to investigate the mechanisms of disease and for pharmaceutical companies to explore new drug targets. At the heart of this technology is a method … Continue reading →
