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 […]



Faster super-resolution microscope can see virus particles moving through a cell

This image taken by the new microscope shows a living bone cancer cell with nucleus (blue), mitochondria (green) and cytoskeleton (magenta). When you want to look at something small up close, you use a microscope. And when you want to look at something really really small, you use a super-resolution microscope. These tools can look […]



A prosthetic leg that can sense touch makes it easier for amputees to walk

September 21st, 2019 at 1:04 am » Comments Off

The prosthesis tries to replicate the nervous system’s feedback loop. The issue: People who walk on both legs rely on constant feedback between their nerves and their brain to get around. But people using a prosthesis don’t have this brain-foot loop, which can make harder to walk confidently. A new bionic prosthesis, developed by researchers […]
