Researchers Engineer Plant Cell Walls to Boost Sugar Yields for Biofuels
March 29, 2013 — Using the tools of synthetic biology, researchers are engineering healthy plants whose lignocellulosic biomass can more easily be broken down into simple sugars for the production of clean, green and ... > full story -
Gene Discovery May Yield Lettuce That Will Sprout in Hot Weather
March 29, 2013 — Plant scientists have identified a lettuce gene and related enzyme that put the brakes on germination during hot weather -- a discovery that could lead to lettuces that can sprout year-round, even at ... > full story -
Head-on Collisions Between DNA-Code Reading Machineries Accelerate Gene Evolution
March 29, 2013 — The bacteria Bacillus subtilis places some of their genes in prime collision paths for the moving molecular machineries that read the DNA code. This spatial-organization tactic to evolve and adapt ... > full story -
DNA: How to Unravel the Tangle
March 29, 2013 — A chromosome is rarely found in the shape we are used to seeing in biology books, that is to say the typical double rod shape (the X pattern, to put it simply). It is usually “diluted” in ... > full story -
Stem Cell Fate Depends on 'Grip'
March 28, 2013 — Scientists have generated new insight on how a stem cell's environment influences what type of cell a stem cell will become. They have shown that whether human mesenchymal stem cells turn into fat or ... > full story -
Biological Transistor Enables Computing Within Living Cells
March 28, 2013 — Bioengineers have taken computing beyond mechanics and electronics into the living realm of biology. Scientists have used a biological transistor made from genetic material -- DNA and RNA -- in place ... > full story -
Protective Prion Keeps Yeast Cells from Going It Alone
March 28, 2013 — A team of scientists has added markedly to the job description of prions as agents of change, identifying a prion capable of triggering a transition in yeast from its conventional single-celled form ... > full story -
Mixed Signals: Combinations of Estrogen-Mimicking Chemicals Strongly Distort Hormone Action
March 28, 2013 — What happens when -- as in the real world -- an individual is exposed to multiple estrogen-mimicking chemicals at the same time? Researchers have used new techniques to study exposure to low doses of ... > full story -
Parkinson's Disease Protein Gums Up Garbage Disposal System in Cells
March 28, 2013 — With a new neuron model system of Parkinson's disease pathologies, researchers have demonstrated that these aberrant clumps in cells resist degradation as well as impair the function of the ... > full story -
Brain's 'Molecular Memory Switch' Identified
March 28, 2013 — Scientists have identified a key molecule responsible for triggering the chemical processes in our brain linked to our formation of memories. The findings reveal a new target for therapeutic ... > full story
