Doctoral student Alejandro Suárez Mascareño, of the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), and his thesis directors at the IAC Rafael Rebolo and Jonay Isaí González Hernández, have discovered a

The Vela supercluster in its wider surroundings: The image displays the smoothed redshift distribution of galaxies in and around the Vela supercluster (larger ellipse; VSC). The centre of the image, so-called the Zone of Avoidance, is covered by the Milky Way (with its stellar fields and dust layers shown in grey scale), which obscures all

PIWI-interacting RNAs, or piRNAs for short, are a class of ‘small regulatory RNAs’ — tiny pieces of nucleic acid just 22-30 nucleotides in length. They may be small, but with their associated Argonaute proteins, piRNAs have the power to ‘silence’ transposable elements, so called egoistic genes found in the genomes of plants, fungi, and animals.

Well-established research suggests extensive plaques and tangles in the brain result in the death of neurons and are an indicator of Alzheimer’s dementia. But surprising new Northwestern Medicine research on the brains of individuals 90 years and older who had superior memories until their deaths revealed widespread and dense Alzheimer’s plaques and tangles in some

Children who drink whole milk are leaner and have higher vitamin D levels than those who drink low-fat or skim milk, new research suggests Children who drink whole milk are leaner and have higher vitamin D levels than those who drink low-fat or skim milk, new research suggests. Children who drank whole (3.25 per cent

A tiny, wearable acoustic sensor developed by researchers can be used to monitor heart health and recognize spoken words.

The star Kepler 11145123 is the roundest natural object ever measured in the universe. Stellar oscillations imply a difference in radius between the equator and the poles of only 3 km. This star is significantly more round than the Sun. © Illustration: Mark A. Garlick Scientists measure the shape of Kepler 11145123 with unprecedented precision
