“CRISPR” stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are the hallmark of a bacterial defense system which forms the basis for the popular CRISPR-Cas9 genome editing technology.
CRISPR-Cas9 is a genome editing tool that is creating a buzz in the science world. It is faster, cheaper and more accurate than previous techniques of editing DNA and has a wide range of potential applications.
Johns Hopkins University researchers developed a robotic surgical system called the Smart Tissue Automation Robot (STAR). It features a 3D imaging system and a near-infrared sensor to spot fluorescent markers along the edges of the tissue to keep the robotic suture needle on track. Unlike most other robot-assisted surgical systems, it operates under the surgeon’s supervision, but without hands-on guidance.
A few months back, China’s Scientist He Jiankui had announced that he was successfully edited the genes of Twins named Lulu and Nana so that they won’t get affected by HIV virus which causes AIDS. He used CRISPR gene editing tool for achieving this.
Since this kind of Gene-editing is illegal in most of the Countries including China, He Jiankui was put under house arrest by the Chinese Government.
Scientists have found that Pancreatic cells that don’t normally produce insulin can be modified to do so, and to help control blood sugar levels in diabetic mice.
The destruction of a single kind of insulin-producing cell in the pancreas can lead to diabetes — but a study suggests that other cells could be modified to take its place and help to control blood sugar levels.
Vitamin D has been found to speed up the clearance of tuberculosis
(TB) bacteria from the lungs of people with multi-drug resistant TB,
according to a study of 1,850 patients receiving antibiotic treatment,
led by Queen Mary University of London.
Lead researcher Professor Adrian Martineau
from Queen Mary University of London said: “Multi-drug resistant TB is
on the rise globally. It’s notoriously difficult to treat, and it
carries a much worse prognosis than standard TB.
“Our study raises the possibility that vitamin D – which is very safe
and inexpensive – could benefit this hard-to-treat group of patients by
taking a novel approach to their treatment. By adding vitamin D to
antibiotic treatment, we can boost the immune system to help the body to
clear TB bugs, rather than relying on antibiotics on their own to kill
the bacteria directly.
