Red-Supergiant Supernova: Secrets of an Earlier Universe

Four images of supernova exploding
Panels A-D (clockwise from upper left) show several different stages of the supernova: the location of the host galaxy after the supernova faded, the three images of the host galaxy and the supernova at different phases in its evolution, the three different faces of the evolving supernova, and the different colors of the cooling supernova.

Detailed telescope images help scientists learn more about the Universe two billion years after the Big Bang. An international research team led by the University of Minnesota Twin Cities has measured the size of a star dating back 2 billion years after the Big Bang, or more than 11 billion years ago...

High-performance thermoelectric devices for energy harvesting and cooling

Yanliang Zhang, associate professor of aerospace and mechanical engineering at the University of Notre Dame, and collaborators Alexander Dowling and Tengfei Luo have developed a machine-learning assisted superfast new way to create high-performance, energy-saving thermoelectric devices.

The novel process uses intense pulsed light to sinter thermoelectric material in less than a second (conventional sintering in thermal ovens can take hours). The team sped up this method of turning nanoparticle inks into flexible devices by using machine learning to determine the optimum conditions for the ultrafast but complex sintering process.

The achievement was just published in the journal Energy and Environmental Scie...

Huge Extragalactic Structure found Hiding behind the Milky Way

Huge extragalactic structure found hiding behind the Milky Way
False-color Z (blue), J (green), and Ks (red) image of a region corresponding to the galaxy group/cluster candidate. The red dashed circle delimits the six arcmin radius central area, the green lines indicate the two long-slit positions and the red squares show the five galaxies observed with F2. In the right panels we zoomed the 58 galaxy candidates within the studied area. The length of each box side is 20 arcsec. Credit: arXiv (2022). DOI: 10.48550/arxiv.2210.16332

A team of researchers with members from Universidad Nacional de San Juan, Universidade Federal do Rio Grande do Sul and Universidad Andres Bello has found evidence of a large extragalactic assembly hiding behind one part of the Milky Way galaxy...

Hormone discovery could Predict Long Term Health of Men

ISMalehormone1122JI

Researchers have discovered the vital role of a hormone, that develops in men during puberty, in providing an early prediction of whether they could develop certain diseases in later life.

Scientists from the University of Nottingham have discovered that the novel insulin-like peptide hormone, called INSL3, is consistent over long periods of time and is an important early biomarker for prediction of age-linked disease. Their latest findings have been published today in Frontiers in Endocrinology.

INSL3 is made by the same cells in the testes that make testosterone, but unlike testosterone which fluctuates throughout a man’s life, INSL3 remains consistent, with the level at puberty remaining largely the same throughout a man’s life, decreasing only slightly into old age...
