A New DNA Sequencing Startup Wants to Pay You For Your Genetic Data. In Brief A genetic sequencing startup is offering kits to sequence your exome, about 1% of the total genome, and will pay you to submit your results to studies.

A New DNA Sequencing Startup Wants to Pay You For Your Genetic Data

Crowdsourcing isn't just a good way to fund videogames; working together with these startups, we can provide more data to help us best understand disease. Sequencing Startups. Scientists Are Inching Closer to Bringing Synthetic Human DNA to Life. GP-Write, Meeting Again In May 2016, more than 100 experts in bioengineering and genetics convened for a private meeting at Harvard Medical School.

The press were not permitted to attend, and participants were asked not to post about the event on social media. Ancient Microbes Found in Neanderthal Plaque DNA. Autism Researchers Discover Genetic ‘Rosetta Stone’ Distinct sets of genetic defects in a single neuronal protein can lead either to infantile epilepsy or to autism spectrum disorders (ASDs), depending on whether the respective mutations boost the protein’s function or sabotage it, according to a new study by UC San Francisco researchers.

Autism Researchers Discover Genetic ‘Rosetta Stone’

Tracing how these particular genetic defects lead to more general changes in brain function could unlock fundamental mysteries about how events early in brain development lead to autism, the authors say. 4 Beneficial Evolutionary Mutations That Humans Are Undergoing Right Now. Most random genetic changes caused by evolution are neutral, and some are harmful, but a few turn out to be positive improvements.

4 Beneficial Evolutionary Mutations That Humans Are Undergoing Right Now

These beneficial mutations are the raw material that may, in time, be taken up by natural selection and spread through the population. Multiplexing Genetic and Nucleosome Positioning Codes: A Computational Approach. Abstract Eukaryotic DNA is strongly bent inside fundamental packaging units: the nucleosomes.

Multiplexing Genetic and Nucleosome Positioning Codes: A Computational Approach

It is known that their positions are strongly influenced by the mechanical properties of the underlying DNA sequence. Here we discuss the possibility that these mechanical properties and the concomitant nucleosome positions are not just a side product of the given DNA sequence, e.g. that of the genes, but that a mechanical evolution of DNA molecules might have taken place. We first demonstrate the possibility of multiplexing classical and mechanical genetic information using a computational nucleosome model. In a second step we give evidence for genome-wide multiplexing in Saccharomyces cerevisiae and Schizosacharomyces pombe.

Maybe you’ve wondered, as I have, how it could possibly be that all of the different types of cells in our bodies are made up of the same DNA chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

These chemicals pair of into A/T and C/G base pairs which then form into sequences, or “genes.” Craig Venter: Watch me unveil "synthetic life" Riccardo Sabatini: How to read the genome and build a human being. Scientists Identify Gene Behind Evolution in Action in Darwin's Finches. Researchers Observe Grafted Plants Sharing Genomic Information. Epigenetic Communication The grafting of one plant onto another is as old as the discovery of agriculture itself (or nearly so); but what has remained mysterious was how the resultant mélange of plant species functioned as a conjoined organism.

Researchers Observe Grafted Plants Sharing Genomic Information

Scientists at the Salk Institute and Cambridge University have taken a big step toward understanding how it all works, with important implications for agricultural science, and possibly opening up new avenues for the creation of novel forms of genetically-modified (GM) organisms and crop species. The new research, which was published in the Proceedings of the National Academy of Sciences for the week of January 18, 2016, shows that grafted organisms communicate and interact on a genomic level—though not through the transference of actual DNA. Rather, they communicate epigenetically. “Our study showed genetic information is actually flowing from one plant to the other. 23andMe Rides Again: FDA Clears Genetic Tests To Predict Disease Risk.

Gene drives spread their wings. Genies are said to have the power to grant three wishes.

Gene drives spread their wings

But genies recently released from laboratory flasks promise to fulfill nearly any wish a biologist can dream up. End the scourge of insect-borne diseases? Check. Inoculate endangered amphibians against killer fungi? Yes. Making of Europe unlocked by DNA. DNA sequenced from nearly 40 ancient skeletons has shed light on the complex prehistoric events that shaped modern European populations.

Making of Europe unlocked by DNA

A study of remains from Central Europe suggests the foundations of the modern gene pool were laid down between 4,000 and 2,000 BC - in Neolithic times. These changes were likely brought about by the rapid growth and movement of some populations. DNA/genetics. DNA. Deoxyribonucleic acid (DNA) is a long chain organic molecule that contains the coding for all metabolic and reproductive processes of all living organisms, save for certain viruses.


This helix shaped molecule consists of a spine that contains a sequence of nucleotides, whose order comprise the coding instruction for each specific lifeform. DNA itself is not alive, but holds the instruction set for building a vast array of proteins as well as its own replication. By governing the synthesis of proteins, DNA is inherently the key substance for the maintenance and replication of every cell in nature, as well as DNA-containing viruses that subsist in another organism's host cells. Most DNA is contained in cell nuclei except for mitochondrial DNA—this is contained in cell organelles or chloroplasts. Double helix DNA model The double helix Sense and anti-sense strands. Genetics. DNA from the Beginning -animated experiments. DNA from the Beginning is organized around key concepts.

The science behind each concept is explained by: animation, image gallery, video interviews, problem, biographies, and links.

Might Alien Life Evolve Like the Incredible Octopus? By Natalie Shoemaker Consider the octopus: a creepy skeleton-less creature with limbs that have regenerative properties and a mind of their own.

AMSTERDAM—Insecure about your height? You may want to avoid this tiny country by the North Sea, whose population has gained an impressive 20 centimeters in the past 150 years and is now officially the tallest on the planet.

DNA study shows Celts are not a unique genetic group. 18 March 2015Last updated at 14:00 ET By Pallab Ghosh Science correspondent, BBC News "What's fascinated historians is why over such a short space of land, the people are so different", as Pallab Ghosh reports A DNA study of Britons has shown that genetically there is not a unique Celtic group of people in the UK. According to the data, those of Celtic ancestry in Scotland and Cornwall are more similar to the English than they are to other Celtic groups.

The study also describes distinct genetic differences across the UK, which reflect regional identities.
