CRISPR enzyme programmed to kill viruses in human cells

November 10th, 2019 at 5:15 pm » Comments Off

Researchers harness Cas13 as an antiviral and diagnostic for RNA-based viruses Researchers have now turned a CRISPR RNA-cutting enzyme into an antiviral that can be programmed to detect and destroy RNA-based viruses in human cells. Many of the world’s most common or deadly human pathogens are RNA-based viruses — Ebola, Zika and flu, for example […]



Nanoparticle tech reduces celiac disease symptoms by 90%

November 6th, 2019 at 12:53 pm » Comments Off

People with celiac disease have two options in life, neither of which is ideal. Because their immune systems can’t tolerate gluten, they can choose to never eat the many delicious foods containing it. Boring. Or they can devour all the cake, bread, and beer they want — but resign themselves to abdominal pain, diarrhea, and […]



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” […]



Mini brains grown in the laboratory produce brainwaves. Now what?

October 20th, 2019 at 1:08 pm » Comments Off

It’s hard to study the human brain. It is the most complex in the animal kingdom with its massive collection of neurons, 80-100 billion to be exact, three times more than chimpanzees. Research relating our brains to the brains of mice and monkeys can only go so far. And because of this complexity, scientists often […]



Humans hava a ‘Salamander-like’ ability to regenerate damaged body parts, study finds

October 15th, 2019 at 12:31 pm » Comments Off

  Axolotls (pictured) have a remarkable ability to regenerate lost body parts. Salamanders are renowned for their regenerative capabilities, such as growing back entire limbs. We can’t pull off this biological trick, but new research highlights a previously unknown regenerative ability in humans—one held over from our evolutionary past. Our bodies have retained the capacity […]
