Hacking Humans : Search & replace gene editing is here

November 1st, 2019 at 11:21 am » Comments Off

The introduction of CRISPR changed the world of genetic engineering by allowing researchers to “cut and paste” DNA. But the process can introduce errors that produce unpredictable results. A recently published report in the journal Nature by David Liu, a Harvard university biologist, describes a new process that is more like a “search and replace” […]



Gene editing transforms gel into shape-shifting material

September 10th, 2019 at 3:23 am » Comments Off

  The CRISPR technique can trigger the new material to release drugs or pick up biological signals Is there anything CRISPR can’t do? Scientists have wielded the gene-editing tool to make scores of genetically modified organisms, as well as to track animal development, detect diseases and control pests. Now, they have found yet another application […]



Gene-edited cattle have a major screwup in their DNA

September 6th, 2019 at 11:29 am » Comments Off

  Bid for barnyard revolution is set back after regulators find celebrity “hornless” bovines contaminated by bacterial genes. They were the poster animals for the gene-editing revolution, appearing in story after story. By adding just a few letters of DNA to the genomes of dairy cattle, a US startup company had devised a way to […]



In a 1st, doctors in U.S. use CRISPR tool to treat patient with genetic disorder

August 16th, 2019 at 12:25 am » Comments Off

Victoria Gray, 34, of Forest, Miss., volunteered for one of the most anticipated medical experiments in decades: the first attempt to use the gene-editing technique CRISPR to treat a genetic disorder in the U.S. For the first time, doctors in the U.S. have used the powerful gene-editing technique CRISPR to try to treat a patient […]



Wait, What? The first human-monkey hybrid embryo was just created in China

August 14th, 2019 at 6:57 am » Comments Off

Last week, news broke that a prominent stem cell researcher is making human-monkey chimeras in a secretive lab in China. The story, first reported by the Spanish newspaper El País, has all the ingredients of a bombshell. First, its protagonist is the highly-respected Dr. Juan Carlos Izpisúa Belmonte, a Spanish-born stem cell biologist at the […]



How scientists built a ‘living drug’ to beat cancer

August 7th, 2019 at 12:07 pm » Comments Off

IN 2010, EMILY Whitehead was diagnosed with Acute Lymphoblastic Leukemia, a cancer of certain cells in the immune system. THIS IS THE most common form of childhood cancer, her parents were told, and Emily had a good chance to beat it with chemotherapy. Remission rates for the most common variety were around 85 percent. It […]



Using CRISPR to resurrect the dead

July 8th, 2019 at 12:10 pm » Comments Off

Gene-editing breakthroughs could allow us to bring extinct species, like the woolly mammoth, back from the dead. But should we? It really is worse than you think. We’ve gorged ourselves on fossil fuels, vacuumed up the Earth’s forests and spewed toxic gases into the atmosphere for years on end. The planet is getting warmer, we’re […]



His DNA solved a century-old jailhouse rape. The victim: His Grandmother

June 18th, 2019 at 11:39 am » Comments Off

Commercial DNA tests showed that Hiram and Bruce were related. But their link proved to be much deeper — and darker — than either could have imagined. As a black teenager in Compton, California, in the 1970s, Hiram Johnson began to wonder about his father’s fine curly hair, and the light-brown skin that strangers sometimes […]



Scientists created bacteria with a synthetic genome. Is this artificial life?

June 3rd, 2019 at 11:23 am » Comments Off

  A colored scanning electron micrograph of the bacteria E. coli. Scientists in Britain created bacteria with “recoded” DNA. In a milestone for synthetic biology, colonies of E. coli thrive with DNA constructed from scratch by humans, not nature. Scientists have created a living organism whose DNA is entirely human-made — perhaps a new form […]



This DIY biohacker is under investigation

May 26th, 2019 at 2:52 am » Comments Off

Josiah Zayner rose to internet fame after performing various biohacking stunts on himself — including a livestreamed attempt to edit his own genes using CRISPR. Those antics are coming to haunt Zayner. Now, the California Department of Consumer Affairs (DCA) is investigating a “complaint of unlicensed practice of medicine” filed against him — a strange […]



CRISPR gene editing is coming for the womb

May 7th, 2019 at 11:28 am » Comments Off

  When an unborn baby is diagnosed with a life-threatening defect, it can be devastating. So some scientists hope to treat the fetus in the uterus, using gene editing. WILLIAM PERANTEAU IS the guy parents call when they’ve received the kind of bad news that sinks stomachs and wrenches hearts. Sometimes it’s a shadow on […]



CRISPR is now being used on humans in the U.S.

May 6th, 2019 at 11:27 am » Comments Off

The gene editing trial has two patients so far. CRISPR therapies are entering the mainstream. The first U.S. trial of CRISPR in humans has begun, NPR reported Tuesday. Two patients are currently being treated as part of a University of Pennsylvania study. Per NPR, both have difficult-to-treat forms of cancer and both have relapsed after […]
