1. Diabetes Vaccine Gives Promising Results in A Genetic Subgroup

A clinical study has investigated whether immunotherapy against type 1 diabetes can preserve the body’s own production of insulin. The results suggest that injection of a protein, GAD, into lymph nodes can be effective in a subgroup of individuals.

2. Researchers Create Sterile Male Mosquitoes Using CRISPR/Cas9

A research team has made a breakthrough in one technique for controlling populations of Aedes aegypti, a mosquito that transmits dengue, yellow fever, Zika and other viruses. The study documents the first use of CRISPR/Cas9 gene editing to target a specific gene tied to fertility in male mosquitoes. The researchers were then able to discern how this mutation can suppress the fertility of female mosquitoes.

3. Good Bacteria Can Temper Chemotherapy Side Effects

A new study found that specific types of gut bacteria can protect other good bacteria from cancer treatments — mitigating harmful, drug-induced changes to the gut microbiome. By metabolizing chemotherapy drugs, the protective bacteria could temper short- and long-term side effects of treatment.

4. New Technique Breaks the Mould For 3D Printing Medical Implants

A research team has overturned the conventional 3D printing approach. Instead of making the bioscaffolds directly, the team 3D printed moulds with intricately-patterned cavities then filled them with biocompatible materials, before dissolving the moulds away. Using the indirect approach, the team created fingernail-sized bioscaffolds full of elaborate structures that, until now, were considered impossible with standard 3D printers.

5. Three Years Younger in Just Eight Weeks? A New Study Suggests Yes!


Source: Impact Journals LLC 27 May 2021


A groundbreaking clinical trial shows we can reduce biological age (as measured by the Horvath 2013 DNAmAge clock) by more than three years in only eight weeks with diet and lifestyle through balancing DNA methylation. A first-of-its-kind, peer-reviewed study provides scientific evidence that lifestyle and diet changes can deliver immediate and rapid reduction of our biological age. Since aging is the primary driver of chronic disease, this reduction has the power to help us live better, longer.

6. New Tool Activates Deep Brain Neurons by Combining Ultrasound, Genetics

Neurological disorders such as Parkinson’s disease and epilepsy have had some treatment success with deep brain stimulation, but those require surgical device implantation. A multidisciplinary team has developed a new brain stimulation technique using focused ultrasound that is able to turn specific types of neurons in the brain on and off and precisely control motor activity without surgical device implantation.

7. Detecting Skin Disorders Based on Tissue Stiffness with A Soft Sensing Device

By putting a piece of soft, strain-sensing sheet on the skin may be able to detect skin disorders non-invasively and in real-time very soon. A research team has designed a simple electromechanical device that can be used for deep tissue pathology diagnosis, such as psoriasis, in an automated and non-invasive fashion. The findings will lay a foundation for future applications in the clinical evaluation of skin cancers and or dermatology diseases.

8. Researchers Create New CRISPR Tools to Help Contain Mosquito Disease Transmission


Source: University of California - San Diego 28 May 2021


Scientists have now developed several genetic editing tools that help pave the way to an eventual gene drive designed to stop Culex mosquitoes from spreading disease. Gene drives are designed to spread modified genes, in this case those that disable the ability to transmit pathogens, throughout the targeted wild population.
