Fast-mutating DNA sequences shape early development; guided evolution of uniquely human traits
What does it mean to be human? According to scientists the key lies, ultimately, in the billions of lines of genetic code that comprise the human genome. The problem, however, has been deciphering that code. But now, researchers at the Gladstone Institutes have discovered how the activation of specific stretches of DNA control the development of uniquely human characteristics -- and tell an intriguing story about the evolution of our species.

Single-cell genome sequencing gets better
Researchers led by bioengineers at the University of California, San Diego have generated the most complete genome sequences from single E. coli cells and individual neurons from the human brain. Preliminary data suggest that individual neurons from the same brain have different genetic compositions. The breakthrough, published in Nature Biotechnology, comes from a new single-cell genome sequencing technique that confines genome amplification to fluid-filled wells with a volume of just 12 nanoliters.

TGen-led study reveals TWEAK-Fn14 as key drug target
A cellular pathway interaction known as TWEAK-Fn14, often associated with repair of acute injuries, also is a viable target for drug therapy that could prevent the spread of cancer, especially brain cancer, according to a study led by the Translational Genomics Research Institute.

Dartmouth researcher finds novel genetic patterns that make us rethink biology and individuality
Scott Williams, Ph.D., of the iQBS at Dartmouth, has made two novel discoveries: 1) a person can have several DNA mutations in parts of their body, with their original DNA in the rest -- resulting in several different genotypes in one individual -- and 2) some of the same genetic mutations occur in unrelated people. We think of each person's DNA as unique, but if a person can have more than one genotype, this may have broad implications.

Cost-effective method accurately orders DNA sequencing along entire chromosomes
A new computational method has been shown to quickly assign, order and orient DNA sequencing information along entire chromosomes. The method may help overcome a major obstacle that has delayed progress in designing rapid, low-cost -- but still accurate -- ways to assemble genomes from scratch. Data gleaned through this new method can also validate certain types of chromosomal abnormalities in cancer.

UNH, UC Davis launch network to study environmental microbes
A grant to the University of New Hampshire and the University of California, Davis, will help biologists identify an abundant yet largely unknown category of organisms, leading to better understanding of the vital environmental functions they play. The National Science Foundation awarded the universities $500,000 to develop a Research Coordination Network on eukaryotic biodiversity. The work will apply new genome sequencing technology to study and classify microscopic eukaryote species like nematodes, fungi, and single-celled animals.

Nature's great diversity: Remarkable 277 new wasp species from Costa Rica
Costa Rica reveals astonishing biodiversity of braconid wasps, with 277 new species of the tribe Heterospilini described, from a total of 286 attributed to the group. The study published in the open access journal ZooKeys is the second part of an extensive two-part study of the braconid subfamily Doryctinae from Costa Rica, to reveal the great species diversity within such a small territory.

New computing model could lead to quicker advancements in medical research, according to Virginia Tech
For the past two years, Wu Feng has led a research team that has now created a new generation of efficient data management and analysis software for large-scale, data-intensive scientific applications in the cloud. "Our goal was to keep up with the data deluge in the DNA sequencing space. Our result is that we are now analyzing data faster, and we are also analyzing it more intelligently," Feng said.

Next-generation global e-infrastructure for taxon names registry
Issue no. 346 of ZooKeys has been automatically registered in ZooBank on its day of publication last Friday. This marks the successful deployment of an automated registration-to-publication pipeline for taxonomic names for animals. The innovative workflow sets directions towards building a next-generation e-infrastructure for a common global taxon names registry.

GenSeq: Updated nomenclature for genetic sequences to solve taxonomic determination issues
An improved and expanded nomenclature for genetic sequences is introduced that corresponds with a ranking of the reliability of the taxonomic identification of the source specimens. Verifying the taxonomic identity of the voucher specimens that are the source of genetic materials has become increasingly difficult but remains vitally important; this new nomenclatural system for DNA sequences helps remedy this issue. The study was published in the open access journal Zookeys.

Automated system promises precise control of medically induced coma
Putting patients with severe head injuries or persistent seizures into a medically induced coma currently requires that a nurse or other health professional constantly monitor the patient's brain activity and manually adjust drug infusion to maintain a deep state of anesthesia. Now a computer-controlled system developed by Massachusetts General Hospital investigators promises to automate the process, making it more precise and efficient and opening the door to more advanced control of anesthesia.

Cellular tail length tells disease tale
Simon Fraser University molecular biologist Lynne Quarmby's adventures in pond scum have led her and four student researchers to discover a mutation that can make cilia, the microscopic antennae on our cells, grow too long. When the antennae aren't the right size, the signals captured by them get misinterpreted. The result can be fatal. They have discovered that the regulatory gene CNK2 is present in cilia and controls the length of these hair-like projections.

Evolution of new species requires few genetic changes
Only a few genetic changes are needed to spur the evolution of new species -- even if the original populations are still in contact and exchanging genes. Once started, however, evolutionary divergence evolves rapidly, ultimately leading to fully genetically isolated species, report scientists from the University of Chicago in the Oct. 31 Cell Reports.

TGen-led research shows ability to do next-generation sequencing for patients with advanced cancers
A pilot study led by the Translational Genomics Research Institute and the Virginia G. Piper Cancer Center at Scottsdale Healthcare shows that, even for patients with advanced and rapidly transforming cancer, researchers can find potential therapeutic targets using the latest advances in genomic sequencing. Sequencing spells out, or decodes, the billions of letters of DNA and other genomic data so that clinicians can discover what genetic changes might lead to cancer.

HIV -- Geneticists map human resistance to AIDS
The key to future HIV treatment could be hidden right in our own genes. Everyone who becomes infected deploys defense strategies, and some even manage to hold the virus at bay without any therapy at all. Scientists retraced the entire chain of events in these battles, from the genome of the virus to the genome of the victim. Their research is published in the journal eLife on Oct. 29.
