Astronomers have published the most detailed images seen of galaxies beyond our own yet, revealing their inner workings in unprecedented detail.

The images were created from data collected by the Low Frequency Array (LOFAR), a network of more than 70,000 small antennae spread across nine European countries. The results come from the team’s years of work, led by Dr. Leah Morabito at Durham University. The team was supported in the UK by the Science and Technology Facilities Council (STFC).

As well as supporting science exploitation, STFC also fu...

Benefits of Time-Restricted Eating depend on Age and Sex

Time-Restricted Eating Has Important Health Benefits – Even With Infectious  Diseases Such As COVID-19

Not everyone benefits equally from TRE, but TRE has important health benefits for all. Time-restricted eating (TRE), a dietary regimen that restricts eating to specific hours, has garnered increased attention in weight-loss circles. A new study by Salk scientists further shows that TRE confers multiple health benefits besides weight loss. The study also shows that these benefits may depend on sex and age.

Most TRE studies focus on weight loss in young male mice, but Salk scientists wanted to determine whether TRE confers additional benefits on other populations...

Vascular diseases such as aneurysms, peripheral artery disease and clots inside blood vessels account for 31% of global deaths. Despite this clinical burden, cardiovascular drug advancements have slowed over the past 20 years. The decrease in cardiovascular therapeutic development is attributed to the lack of efficiency in converting possible treatments into approved methods, specifically due to the discrepancy between studies that take place outside the body compared to inside.

Researchers at Texas A&M University aim to remodel current methodologies to minimize this gap and improve the translatability of these techn...

Cracking a Mystery of Massive Black Holes and Quasars with Supercomputer Simulations

Distribution of gas across scales, with the gas density increasing from purple to yellow. The top left panel shows a large region containing tens of galaxies (6 million light-years across). Subsequent panels zoom in progressively into the nuclear region of the most massive galaxy and down to the vicinity of the central supermassive black hole. Gas clumps and filaments fall from the inner edge of the central cavity occasionally feeding the black hole. Credit: Anglés-Alcázar et al. 2021, ApJ, 917, 53.
