Scientists grow working human beta cells that can end diabetes in mice

Scientists grow working human beta cells that can end diabetes in mice Since we know that diabetes has to do with defective or missing beta cells, we have a very obvious candidate for treatment: Put in functioning beta cells to replace the bad or missing ones.The problem has always been growing those replacement cells properly, directing early-stage stem cells with the ability to “differentiate” into most possible cells to become specifically fully adult pancreatic beta cells.

‘Gene drive’ breakthrough creates weaponized mosquito extinction strain

‘Gene drive’ breakthrough creates weaponized mosquito extinction strain The name for this power is called gene drive.First, it forces itself into 99% of a mosquito’s sperm cells, and thus into 99% of its offspring.

‘Genetic unicorns’ hint at how we can defy our molecular destiny

‘Genetic unicorns’ hint at how we can defy our molecular destiny Similarly, the Nature study suggests there is more to genetic mutations than is currently accounted for by our present understanding of the subject.” Each year, thousands of babies are screened for Mendelian disorders and terminated or brought to term on the basis of the results.

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 identify autism-linked receptor that initiates synaptic pruning

Researchers identify autism-linked receptor that initiates synaptic pruning Disruptions in the delicate process of synaptic pruning are associated with disorders like schizophrenia and autism, which makes them hot topics for neuroscience research.Adolescent synaptic pruning is important for normal learning and memory function in adulthood.

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.

Hemophilia ‘cures’ are proving gene therapy really is all it’s cracked up to be

The latest example is hemophilia, and the incredible recent progress toward a cure (or cures) show just how much potential the field really has.About 1 in 5,000 males is born with Hemophilia A, which has to do with the function of the protein factor VIII, and 1 in 30,000 is born with hemophilia B, due to defective versions of factor IX.

This genetically engineered ‘living robot’ moves with rat heart cells

This genetically engineered ‘living robot’ moves with rat heart cells Plus: robot stingray!The hope is that building these sorts of projects, and learning how to better manipulate and develop heart cells to achieve certain aims, we’ll gain a better understanding of how heart cells work, and how whole hearts pump fluid throughout the body.

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.

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.
