Although it’s been a tough winter for many people in the U.S., summer is coming. And that means backyard barbeques, fun on the beach and, of course, slathering on sunscreen. But one particular environmentally friendly sunscreen ingredient has been difficult to obtain – shinorine, could only be harvested from nature. Scientists now report in ACS Synthetic Biology the laboratory production of that compound.

Sunscreen is key to protecting the skin from carcinogenic UV radiation. However, some synthetic sunscreen components can accumulate in aquatic environments and potentially cause harm by acting as hormone disruptors...

“By delivering red wine antioxidants during conventional angioplasty, it may be possible to prevent excess tissue from building up and the blood vessel from narrowing again as it heals,” Dr. Dugas said.

Antioxidants found in wine have advanced stents. Antioxidant compounds found in red wine are advancing the treatment of heart disease – the leading cause of death for both men and women in the U.S. Heart disease occurs when plaque builds up within artery walls blocking the blood flow through tissues in the body, increasing the risk of a heart attack or stroke. About 630,000 people die each year from heart disease, according to the Centers for Disease Control and Prevention.

While there is no singular cure for heart disease, there are numerous forms of treatment including lifestyle chang...

The structure of human telomerase reverse transcriptase (hTERT). Human TERT contains four key domains: the telomerase essential N-terminal (TEN) domain; the TERT RNA binding (TRB) domain; the reverse transcriptase (RT) domain and the C-terminal extension (CTE) domain.

Researchers from several institutions, including, UCLA, Boston University, Stanford University and the Institute for Aging Research at Hebrew SeniorLife, analyzed blood samples from nearly 10,000 people to find that genetic markers in the gene responsible for keeping telomeres (tips of chromosomes) youthfully longer, did not translate into a younger biologic age as measured by changes in proteins coating the DNA.

DNA methylation age is a biomarker of chronological age and predicts lifespan, but its underlying molecular mechan...

Bacteria play a critical role in the development of colon cancer, new research suggests. Credit: Elizabeth Cook

Patients with an inherited form of colon cancer harbor two bacterial species that collaborate to encourage development of the disease, and the same species have been found in people who develop a sporadic form of colon cancer, a study led by a Johns Hopkins Bloomberg~Kimmel Institute for Cancer Immunotherapy research team finds. A second study in mice published concurrently by the same researchers shows a possible mechanism behind how one of these species spurs a specific type of immune response, promoting – instead of inhibiting – the formation of malignant tumors...
