Scientists have improved upon their own previous world-best efforts to pluck out just the right stem cells to address the brain problem at the core of multiple sclerosis and a large number of rare, fatal children´s diseases. Details of how scientists isolated and directed stem cells from the human brain to become oligodendrocytes — the type of brain cell that makes myelin, a crucial fatty material that coats neurons and allows them to signal effectively — were published...

Interfering with cell recruitment reduces damaging inflammation in animals´ models of several disorders Massachusetts General Hospital (MGH) researchers — along with collaborators from Massachusetts Institute of Technology (MIT) and Alnylam Pharmaceuticals — have found a way to block, in an animal model, the damaging inflammation that contributes to many disease conditions. In their report receiving early online publication in Nature Biotechnology, the investigators...

A slight change in molecular structure introduced by genetic engineering gives crop-protecting proteins called Bt toxins a new edge in overcoming resistance of certain pests, a UA-led team of researchers reports in Nature Biotechnology One of the most successful strategies in pest control is to endow crop plants with genes from the bacterium Bacillus thuringiensis, or Bt for short, which code for proteins that kill pests attempting to eat them. But insect pests are evolving resistance...

International scientists map out promising fungi that degrades biomass at high temperature Two heat-loving fungi, often found in composts that self-ignite without flame or spark, could soon have new vocations. The complete genetic makeup of Myceliophthora thermophila and Thielavia terrestris has been decoded by an international group of scientists. The findings, published in Nature Biotechnology, may lead to the faster and greener development of biomass-based fuels, chemicals and other...

Turning Up The Heat On Biomass Pretreatment Processes
2011-10-03 04:43:00

The nation's Renewable Fuels Standard calls for annual production of 36 billion gallons of biofuel by 2022. One of the biggest hurdles to achieving this goal lies in optimizing the multistep process involved in breaking down plant biomass and then converting it into fermentable sugars that can be refined into fuel for our transportation needs. To overcome this challenge, the U.S. Department of Energy supports several projects focused on identifying enzymes from fungi and microbes such as...

  Breakthrough to allow scientists to assemble genomes for thousands of bacteria species that previously couldn't be studied Researchers have developed a new method to sequence and analyze the dark matter of life–the genomes of thousands of bacteria species previously beyond scientists' reach, from microorganisms that produce antibiotics and biofuels to microbes living in the human body. Scientists from UC San Diego, the J. Craig Venter Institute and Illumina Inc.,...

For decades, scientists have studied a laboratory mouse model that develops signs of the paralyzing disease amyotrophic lateral sclerosis (ALS) as they age. In a new study appearing in Nature Biotechnology, investigators at Nationwide Children's Hospital have developed a new model of ALS, one that mimics sporadic ALS, which represents about 90 percent of all cases. ALS, commonly known as Lou Gehrig's disease, is characterized by the death of motor neurons, which are muscle-controlling nerve...

Comprehensive set of mutated mouse microRNAs will drive research A new resource to define the roles of microRNAs is announced today in Nature Biotechnology. The resource, called mirKO, gives researchers access to tools to investigate the biological role and significance for human health of these enigmatic genes. mirKO is a "library" of mutant mouse embryonic stem (ES) cells in which individual, or clustered groups of microRNA genes, have been deleted. Using these tools researchers can create...

A Purdue University scientist is urging federal officials to decide whether genetically engineered salmon would be allowed for U.S. consumption and arguing that not doing so may set back scientific efforts to increase food production. William Muir, a professor of animal sciences, said that based on data made available by the U.S. Food and Drug Administration, AquAdvantage (AA) salmon poses little real risk to the environment or human health. AA salmon were given a gene from Chinook salmon...

The study on single-nucleotide resolution structural variations (SVs) of an Asian and African genome was published online in Nature Biotechnology. This study was performed by BGI (previously known as the Beijing Genomics Institute), the largest genomics organization in the world, and demonstrates that whole genome de novo assembly could serve as a new solution for developing a more comprehensive SV map of individuals. With the rapid development of genomics, more and more experts focus upon...
