‘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.

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.

Chill out, woolly mammoths aren't coming back just yet

Chill out, woolly mammoths aren't coming back just yet Woolly mammoths won't be trouncing through the Arctic tundra anytime soon.Woolly mammoths roamed the planet for hundreds of thousands of years before they vanished about 4,000 years ago.

22 photos that prove science is beautiful

22 photos that prove science is beautiful It's the 20th anniversary of the Wellcome Images Awards, which celebrates images of science and medicine.Their winners’ gallery features the most diverse range of images the contest's history.

Stanford researchers accidentally discover a whole new role for the cerebellum

Stanford researchers accidentally discover a whole new role for the cerebellum Scientists from Stanford have stumbled onto a new and different role for the cerebellum — and they found it while they were looking for something else entirely.Some granule cells lit up as expected, when a mouse was planning and executing arm movements.

Scientists wants this CRISPR pill to one day replace antibiotics

Scientists wants this CRISPR pill to one day replace antibiotics Their weapons of choice are deception and a powerful gene-editing tool called CRISPR.Initially borrowed from bacteria, which use CRISPR as an immune defense against viruses, the gene-editing tool works by recording snippets of the attacker’s DNA, so that the bacteria can recognize and eliminate future invaders.

Despite What You May Have Heard, Licking Frogs Does Not Cure the Flu

Despite What You May Have Heard, Licking Frogs Does Not Cure the Flu The skin microbiome of certain amphibians could help us figure out how to curb the fungal epidemic called chytridiomycosis that threatens tropical frogs.The strain of flu they were using binds to human cells using lollipop-shaped extensions jutting out from its surface.

Meet CRISPR: Our Genetic Superweapon

Meet CRISPR: Our Genetic Superweapon When we think of genetic damage or mutation, our minds either jump to pulp heroes like Bruce Banner or grotesque, deformed creatures.And it’s all thanks to CRISPR — a genetic superweapon.

Powerful gene-editing tool can eliminate HIV infection in mice

Powerful gene-editing tool can eliminate HIV infection in mice For the first time, a team of researchers has shown that they can remove HIV type 1 (HIV-1) from infected mouse cells using a powerful gene-editing tool.The new work builds on an earlier proof-of-concept study that involved genetically modified, or "transgenic," mice and rats.

CRISPR Moves Us a Step Closer to Quashing HIV

CRISPR Moves Us a Step Closer to Quashing HIV This time, because a team of researchers in China have published a paper detailing their work in adapting CRISPR for use as an HIV cure and the results are pretty stunning.For the stubborn among you, CRISPR is basically a genetic scalpel that allows us to precisely cut and move DNA, however, we’d like to.

Far More People Than Thought Are Carrying Rare Genetic Diseases

Far More People Than Thought Are Carrying Rare Genetic Diseases In fact, the comparison of evolution to a gambler might be the most apt, and nowhere is this more evident than in reference to genetic diseases like hemophilia.Now a recent study published in the Annals of Internal Medicine suggests far more people than previously thought are carrying variants of rare genetic diseases and could force us to redefine what is considered a healthy genome.

Scientists just fit a GIF onto DNA, which might be the most important thing to ever happen to GIF-kind

Scientists just fit a GIF onto DNA, which might be the most important thing to ever happen to GIF-kind But now GIFs are making their way to a new frontier: scientists have finally figured out how to store and retrieve them from bacterial DNA.This means that the recording DNA can capture and replay events in the order in which they occurred.

Controversial Gene Editing Tech Could Be Hard to Control

Controversial Gene Editing Tech Could Be Hard to Control But, another possible use has been gene drive (or the process of manipulating how genes are inherited).For a while now, scientists have suggested that we use CRISPR to, in essence, rid the world of disease-carrying mosquitos — savings tens of millions of lives.

Researchers edited the DNA of viable human embryos in U.S. for the first time, but don't freak out yet

Researchers edited the DNA of viable human embryos in U.S. for the first time, but don't freak out yet The experiment, using the revolutionary genome-editing technique CRISPR-Cas9, was led by Shoukhrat Mitalipov of Oregon Health and Science University.It went beyond previous experiments using CRISPR to alter the DNA of human embryos, all of which were conducted in China, in that it edited the genomes of many more embryos and targeted a gene associated with a significant human disease.

Oregon Scientists First in US to Edit Human Embryos

Oregon Scientists First in US to Edit Human Embryos Still, Mitalipov’s work marks a milestone for the United States—the second country to successfully edit human embryos, after China.Some, like the US National Academies of Science, Engineering, and Medicine, believe modified human embryos should be allowed—as long as researchers follow strict criteria.

CRISPR Used to Genetically Modify Human Embryo in the US

CRISPR Used to Genetically Modify Human Embryo in the US Researchers in the US have limited CRISPR experiments on the human genome, but for the first time, a US team has successfully edited a human embryo with CRISPR.In doing so, the scientists at Oregon Health and Science University also showed CRISPR has the potential to eliminate genetic diseases.

Designer babies are still a long way away, study suggests

Designer babies are still a long way away, study suggests Instead, they copied the healthy gene from their mother and incorporated that into their genome to replace the father’s.That offers the prospect of preventing inherited diseases such as cystic fibrosis, Huntington’s disease, and some cancers, as long as one parent carries a healthy gene to replace the disease-causing one.

Scientists Edit Human Embryos to Curb Disease

Scientists Edit Human Embryos to Curb Disease US scientists successfully edited human embryos to remove faulty DNA that causes hereditary heart disease.“Current treatment options for HCM provide mostly symptomatic relief without addressing the genetic cause of the disease,” according to the paper.

Your future organ donor might be a pig, study suggests

Your future organ donor might be a pig, study suggests Scientists have taken a major step toward enabling pig to human organ transplantation by using a novel gene editing technology known as CRISPR-Cas9.The new research is detailed in a study published in the journal Science on Thursday.
