Astronomers have detected “hot Jupiter” exoplanets transiting two distant stars. The newly found alien worlds, designated EPIC 229426032 b and EPIC 246067459 b, appear to be larger than it should be according to theoretical models. The finding is reported January 24 in a paper published on arXiv.org. The so-called inflated planets are those that expand in size when their parent stars are at the end of their lives. They have been known to astronomers for almost two decades, but it is still unclear what causes the inflation processes...

The quiescent galaxy eMACSJ1341-QG-1 as seen by the Hubble Space Telescope. The yellow dotted line traces the boundaries of the galaxy’s gravitationally lensed image. The inset on the upper left shows what eMACSJ1341-QG-1 would look like if we observed it directly, without the cluster lens. The dramatic amplification and distortion caused by the intervening, massive galaxy cluster (of which only a few galaxies are seen in this zoomed-in view) is apparent. Credit: Harald Ebeling, UH IfA

An international team of has discovered one of the most extreme instances of magnification by gravitational lensing...

“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...
