Primitive Artificial Cells Turned Into Complex Biological Materials
2014-02-04 15:22:51

University of Southern Denmark It is a big dream in science: To start from scratch with simple artificial microscopic building blocks and end up with something much more complex: living systems, novel computers or every-day materials. For decades scientists have pursued the dream of creating artificial building blocks that can self-assemble in large numbers and reassemble to take on new tasks or to remedy defects. Now researchers from University of Southern Denmark have taken a step...

Critical Protein For Healthy Cell Growth In Mammals Discovered
2014-01-28 12:37:01

Penn State University A team of researchers from Penn State University and the University of California has discovered a protein that is required for the growth of tiny, but critical, hair-like structures called cilia on cell surfaces. The discovery has important implications for human health because lack of cilia can lead to serious diseases such as polycystic kidney disease, blindness and neurological disorders. "If we want to better understand and treat diseases related to cilium...

Mitochondrial Ribosome Deciphered
2014-01-24 13:37:28

ETH Zurich Researchers at the Swiss Federal Institute of Technology (ETH) in Zurich have deciphered the structure of part of the ribosome found in mitochondria, the power plants of the cell. The scientists were able to benefit from advancements in the field of electron microscopy and capture images of the mitochondrial ribosome at a level of resolution never achieved before. The ribosome can be thought of as a decryption device housed within the cell. It is able to decipher the genetic...

Do Mitochondrial Genes Matter?
2014-01-14 11:45:32

Uppsala University Contrary to common belief, mitochondrial genes seem to matter for how well individuals survive and reproduce. These new results are reported by researchers at Uppsala University, Sweden, who studied the genes of a common beetle species. Mitochondria are vital power plants of cells. They carry their own genes, which are inherited only through females, and these genes vary greatly between individuals. In the latest issue of the prestigious scientific journal Ecology...

-- Collaboration will focus on enabling detection of known cancer biomarkers in blood plasma NEW YORK, Jan. 13, 2014 /PRNewswire/ -- Exosome Diagnostics today announced an expansion of its strategic collaboration with QIAGEN to develop non-invasive molecular diagnostics for use in detecting and monitoring actionable genetic mutations in lung cancer patients. In contrast with current molecular diagnostics requiring tissue biopsy, the focus will be to enable detection of...

Cilia Use Different Molecular Motors For Different Jobs
2014-01-11 08:19:58

Brown University Cilia are one of nature’s great multipurpose tools. The tiny, hair-like fibers protrude from cell membranes and perform all kinds of tasks in all kinds of creatures, from helping clear debris from human lungs to enabling single-celled organisms to swim. Now, physicists from Brown University have discovered something that could help scientists understand how cilia have been adapted for so many varied tasks. The study, led by graduate student Ilyong Jung, looked at the...

Why Some Petunias Are Blue
2014-01-02 15:01:54

Cell Press Researchers have uncovered the secret recipe to making some petunias such a rare shade of blue. The findings may help to explain and manipulate the color of other ornamental flowers, not to mention the taste of fruits and wine, say researchers who report their findings in the Cell Press journal Cell Reports on January 2nd. From the flowers' point of view, the findings also have important implications, since blue petals instead of red might spell disaster when it comes to...

New research by scientists at the University of Exeter has shown that cells demonstrate remarkable flexibility and versatility when it comes to how they divide - a finding with potential links to the underlying causes of many cancers. The study, published today in Developmental Cell, describes a number of routes to the formation of a microtubule spindle – the tracks along which DNA moves when a cell divides in order to make two genetically identical cells. In order to understand the...

A new gene mutation which will help doctors give a more accurate diagnosis of a particular type of brain and muscle disease in children has been discovered for the first time by University of Leeds experts. Mitochondrial myopathy, as it is known, causes muscle weakness, movement problems and learning difficulties and affects more than 70,000 people in the UK. For the first time, mutations in a particular gene, MICU1, have been linked to myopathy. The discovery gives a better...


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.
