“Chemical nose” smells vital variations in unusual folding of DNA structures

Small variations in the structure of DNA have been related to breast cancer and other diseases, but they have been incredibly hard to find so far.

New technology efficiently detects gene mutation in blood with low error rate

Next-generation gene sequencing (NGS) technologies --in which millions of DNA molecules are simultaneously but individually analyzed-- theoretically provides researchers and clinicians the ability to noninvasively identify mutations in the blood stream.

Study finds how SARS-CoV-2 hijacks human cell machinery to disrupt the immune response

SARS-CoV-2 hijacks human cell machinery to disrupt the immune response, enabling it to cause infection, replicate, and cause disease.

New nanopore sequencing tool can identify the existence of nucleobases

Nanopore technology has the potential to enable the development of portable, low-cost, small devices capable of real-time DNA sequencing.

Study reveals a compound found in avocados helps in the treatment of leukemia

According to recent research at the University of Guelph, a compound found in avocados may one day lead to improved leukemia treatment.

Researchers devise a small-molecule cocktail to protect stem cells from stress

Researchers at the National Institutes of Health (NIH) have devised a four-part small-molecule cocktail that can protect stem cells called induced pluripotent stem cells (iPSCs) from stress and maintain normal stem cell structure and function.

Increased expression of DUSP16 molecule leads to cancer chemoresistance

Chemotherapy is a drug treatment that uses powerful chemicals to kill fast-growing cancer cells in the body. It is a systemic treatment where drugs travel throughout the body and destroy cancer cells that have spread (metastasized) to parts of the body far away from the original (primary) tumour.

Protein in skeletal muscular system may play a key role in the body's fight or flight response

Researchers at the University of Cincinnati say a regulatory protein found in skeletal muscle fiber may play an important role in the body's fight or flight response when encountering stressful situations.

Natural molecule can effectively block the binding of human antibodies to SARS-CoV-2

Researchers have found that a natural molecule can effectively block the binding of a subset of human antibodies to SARS-CoV-2. The discovery may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus.

New enzyme-activated compostable plastic could diminish microplastics pollution

Despite our efforts to sort and recycle, less than 9% of plastic gets recycled in the U.S., and most ends up in landfill or the environment.

Study shows how tau aggregates promote Alzheimer’s disease

If looked deep into the brain of a patient with Alzheimer’s disease or those suffering from the most types of dementia or the concussion-associated syndrome, called chronic traumatic encephalopathy (CTE), there would be hairball-like tangles of a protein known as tau—a common suspected culprit.

New breakthrough in understanding the role of high-risk immune genes in rheumatoid arthritis

Researchers within the Biomedicine Discovery Institute at Monash University have made a breakthrough in understanding the role played by high-risk immune genes associated with the development of rheumatoid arthritis (RA).

Study reveals RNA regulatory mechanisms within transcription-translation couplings

To gain a better understanding of how bacterial RNA gives rise to proteins scientists are now focusing on the special way this process takes place in bacteria.

Ebola virus protein changes shape by using human RNA

The human genome contains the instructions to make tens of thousands of proteins. Each protein folds into a precise shape--and biologists are taught that defined shape dictates the protein's destined function. Tens of thousands of singular shapes drive the tens of thousands of needed functions.
