We’ve seen a number of recent improvements to the CRISPR gene editing method, from enhanced precision to novel techniques to block the process. But despite all these innovations, the technique is generally only able to modify one single gene at a time.

Most people think of turmeric as a kitchen spice, or perhaps as a health supplement that’s taken orally. Now, however, scientists have incorporated curcumin – a compound extracted from turmeric – into a porous foam that’s designed to heal skin wounds with a minimum of scarring. read more

An extraordinarily sensitive new blood test has been developed that promises to be able to effectively track the progression of breast cancer at its earliest stages. It is suggested the blood test could track the efficacy of drug therapies better than current imaging techniques and prevent unnecessary surgical procedures or needless extra doses of chemotherapy. read more

Alkahest, a California-based biotech start-up, has just revealed some compelling early results from an ongoing Phase 2 trial into the efficacy of its novel formulation of plasma proteins derived from young blood, developed to slow, or even stop, the cognitive decline associated with Alzheimer’s disease. read more

Cancer Killer Found in Common Flower

Feverfew is a common flower easily recognizable either from a home garden or the shelf of the local health store. For hundreds of years it’s been used as a traditional medicine for migraines and other pains, though its actual usefulness in that regard is questionable.

When it comes to medical ailments and their diagnosis, time is absolutely of the essence. The sooner we’re aware of a developing condition, the better chance we have of treating and ultimately overcoming it. Lately we’re seeing how artificial intelligence is poised to play a greater and greater role in detecting tell-tale signs of disease long before doctors can, with potentially life-saving ramifications. read more

Outside of expensive transplants and drugs with questionable effectiveness, a proper treatment has continued to elude the great number of scientists working in the realm of hair loss. But sources of optimism are never far away, the latest coming out of Japan’s Yokohama National University where scientists have developed an improved technique they claim brings higher rates of follicle growth and could be scaled up to cover larger, vaster expanses more efficiently. read more

The over-abundance or lack of certain types of gut bacteria has been linked to everything from depression to heart disease to childhood asthma. Non-invasively determining which microbes make up a person’s “gut microbiome,” however, can be difficult – which is why a new 3D-printed capsule was developed. read more

A team of scientists from Israel report compelling new insights into how the metastatic spread of melanoma is assisted by nearby fat cells. The research does not suggest obesity enhances the metastatic potential of skin cancers but it does point to new drugs that can stop the spread of melanoma. read more

How to Protect Transplanted Cells

Bone marrow transplants are a common treatment for certain conditions related to the blood, but the patient’s immune system can often react badly to the foreign cells and attack them. Mesenchymal stromal cells (MSCs) may help, but they too can be cleared out by immune cells. Now, a Harvard team has shown that coating MSCs in a thin hydrogel can protect them, making bone marrow transplants more successful. read more
