Yeast Mothers Sacrifice All For Their Babies
2012-11-09 10:28:33

University of California - San Francisco UCSF discovery shows evolution at work in the laboratory A mother's willingness to sacrifice her own health and safety for the sake of her children is a common narrative across cultures — and by no means unique to humans alone. Female polar bears starve, dolphin mothers stop sleeping and some spider moms give themselves as lunch for their crawly babies' first meal. Now an unexpected discovery at the University of California, San...

Key To Controlling Fruit Ripening Could Be In The Functions Of Chloroplasts
2012-11-01 14:51:47

University of Leicester Biologists may have unearthed the potential to manipulate the functions of chloroplasts, the parts of plant cells responsible for photosynthesis. Researchers in the University of Leicester's Department of Biology discovered that chloroplasts are affected by the ubiquitin proteasome system (UPS) — a process which causes the breakdown of unwanted proteins in cells, previously thought to only act on central parts of the cell. As a result, the researchers...

Titan: World's Fastest Supercomputer Unleashed
2012-10-29 10:21:25

Michael Harper for redOrbit.com — Your Universe Online The Oak Ridge National Laboratory (ORNL) has created a machine capable of doing the unthinkable. In fact, it´s capabilities not only sound impossible, they sound fictional. By combining traditional CPUs with graphical processing units (GPUs), the Titan Supercomputer capable of spitting out 20 petaflops, making it 10 times more powerful than ORNL´s previous Jaguar supercomputer. For the uninitiated, a petaflop, says...

Multicellular bacteria transmit electrons across relatively enormous distances A multinational research team has discovered filamentous bacteria that function as living power cables in order to transmit electrons thousands of cell lengths away. The Desulfobulbus bacterial cells, which are only a few thousandths of a millimeter long each, are so tiny that they are invisible to the naked eye. And yet, under the right circumstances, they form a multicellular filament that can transmit...

RNA-world Hypothesis Under The Microscope
2012-10-15 05:27:46

redOrbit Staff & Wire Reports - Your Universe Online A chemical model developed by a team of US researchers shows how the Earth's first life forms may have packaged the genetic coding material known as ribonucleic acid (RNA), demonstrating one of the earliest steps that could have paved the way for the formation of cellular life some four billion years ago. The Penn State University scientists behind the project used a type of macromolecule called polymers to create primitive...

Body's Own Recycling System
2012-10-12 11:19:21

Researchers discover "molecular emergency brake" in charge of regulating self-digestion Times of distress literally eat away at the core of starving cells: They start to digest their own parts and recycle them for metabolic purposes. This process — called autophagy — also plays a role in immune defense. In that context, however, the digestive machinery is switched on for an entirely different purpose: the elimination of pathogens that have invaded the body. Now, Prof. Ingo...

Cell (journal)
2012-06-04 14:15:36

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 &...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
