DNA Day 2016: Get tested, learn more about what makes you unique

DNA Day 2016: Get tested, learn more about what makes you unique In this month alone, we’ve covered three different stories about how we’re using DNA to solve major problems.If genealogy interests you, AncestryDNA is selling for $79 per kit, and Family Tree DNA kits start at $79 too.

Researchers team up with viruses to evolve a better insecticide

Researchers team up with viruses to evolve a better insecticide Under selective pressure, like an insect being exposed to pesticides, life does what it does best: figure out how to persist through adversity.The Bt endotoxin does its work by binding to cell surface proteins in the insect’s gut, which opens pores that ultimately kill the cells.

Can DNA become the future of digital storage? Microsoft is betting on it

Can DNA become the future of digital storage? Microsoft is betting on it A more interesting challenge comes when we pit machines against evolution in an area she has been optimizing for a long time — like data storage and retrieval.But a parallel process takes place in nature every second of the day: DNA storage and replication.

The synthetic human genome could be around the corner

The synthetic human genome could be around the corner We’ve seen controversial proposals for cloned human beings and three-parent children, mostly in pursuit of fixing some horrible genetic disease — but now, scientists are starting to rumble about the possibility of creating an all-new human genome from scratch.The human genome is more touchy, but we can genetically engineer cultures of human cells, and take individual human genes and put them into similar organisms to see what they do.

How DNA data storage works, as scientists create the first DNA ‘RAM’

How DNA data storage works, as scientists create the first DNA ‘RAM’ Even more impressive, that data was stored in a quickly and easily accessible form, making it more akin to computer RAM, than computer storage.At the end of the day, DNA’s key special attribute it data storage density: how much information can DNA fit into a given unit volume?

Microsoft's huge breakthrough with DNA data storage

Microsoft's huge breakthrough with DNA data storage For most, data storage devices equate to floppy disks (debatable), external hard drives, USBs, CD’s and smart phones.However, researchers at Microsoft and the University of Washington have reached an early milestone by storing a record 200 megabytes of data within DNA.

How MIT’s new biological ‘computer’ works, and what it could do in the future

How MIT’s new biological ‘computer’ works, and what it could do in the future With a fully realized ability to program cell behavior as reliably as we do computer behavior, there’s no telling what biological computing could accomplish.In 2013, this same team designed the computing strain that preceded this one: a biological “state machine.

NASA’s new DNA sequencer on the ISS could be used on aliens

NASA’s new DNA sequencer on the ISS could be used on aliens The regular resupply missions to the International Space Station include the basics like food, but all sorts of new science toys as well.In the Dragon capsule that docked with the station several days ago, there was one particularly interesting device — a DNA sequencer.

Huge Pew study says human augmentation will be a hard sell, but it probably won’t be

Huge Pew study says human augmentation will be a hard sell, but it probably won’t be There are basically two arguments against non-medical human augmentation.The study focuses most powerfully on gene editing of babies and adults, upgraded synthetic blood, and intracranial brain implants for cognitive enhancement.

The gene therapy revolution is coming. Will the US get left behind?

The gene therapy revolution is coming. Will the US get left behind? Last year, the United States federal budget included a rider banning certain types of gene therapy research, and that has some in the scientific community worried.For one, embryonic stem cell research was mostly opposed through funding bans, but more importantly the arguments against it centered on moral and religious arguments, not practical or scientific ones.

Crowdsourced genetics study ferrets out the hereditary roots of depression

Crowdsourced genetics study ferrets out the hereditary roots of depression But in at least one arena, we really are better off together, and that’s when it comes to crowdsourced genetics studies.The real plaudits go to those individuals who gave permission to share their data and make possible the study.

Here come the appeals: White House report attacks modern forensic science

Here come the appeals: White House report attacks modern forensic science The Justice Department and the FBI have both expressed concerns with the report.The FBI said that it “disagrees with many” of the report’s claims that it “makes broad, unsupported assertions regarding science and forensic science practice.

Human skeleton found on shipwreck that held mysterious Antikythera Mechanism

Human skeleton found on shipwreck that held mysterious Antikythera Mechanism They called it the Antikythera device, after the island near which it was found.Cousteau heard of the Antikythera device shortly after the first publication about it, by bespectacled British historian Derek de Solla Price.

Tardigrade DNA inserted into human cells gives them X-ray resistance

Tardigrade DNA inserted into human cells gives them X-ray resistance A study just broke out of Tokyo that says some eyebrow-raising things about water bears and their DNA.First among the revelations is the finding that water bears might not be all that much not-tardigrade at all.

Scientist claims 115 is the hard limit on human lifespan, but it’s not that simple

Scientist claims 115 is the hard limit on human lifespan, but it’s not that simple Jan Vijg of the Albert Einstein College of Medicine has made a heavily qualified assertion that the maximum human lifespan is 115 years, plus or minus a bit.Since the data don’t show anyone living past about 115, with a very few notable exceptions, Vijg says that the data “strongly suggests” that 115 represents a hard limit to human longevity.

Researchers discover a virus that makes the toxin from black widow spider venom

Researchers discover a virus that makes the toxin from black widow spider venom Biotechnologists have discovered some horrifying new consequences of lateral gene transfer: a virus that started making the toxin from black widow spider venom, all by itself.It’s even less comforting that the virus acquired the ability to make the black widow toxin all on its own.

Genetic Sudoku is here, and it vastly speeds genomic analysis

Genetic Sudoku is here, and it vastly speeds genomic analysis The innovation has to do with one of the most powerful techniques in genetic analysis: whole genome knockout collections.Expose enough bacteria and you can be assured that you’ve got a mutation into every gene in an organism.

Scientists figure out how to tweak plant genomes to boost photosynthesis

Scientists figure out how to tweak plant genomes to boost photosynthesis Ample sunlight is good…except when there’s too much of it, which can cause damage to the plant’s cells.As the sun moves across the sky, changes in light can leave many leaves in the shade with a depressed rate of photosynthesis.
