It’s a mystery that’s puzzled astronomers for years. Which came first, supermassive black holes or the galaxies that surround them? The post Supermassive Black Holes or Their Galaxies? Which Came First? appeared first on Universe Today.... Read more »

All stars die, some more violently than others. Once our own Sun has consumed all the hydrogen fuel in its core, it too will reach the end of its life. Astronomers estimate this to be a short 7 billion years from now. For a few million years, it will expand... Read more »

For the first time, astronomers are able to accurately simulate galaxies from shortly after the big bang to today by including a realistic treatment of the effects stars have on their host galaxies. For the past few decades astronomers have simulated galaxies by mixing the basic physical ingredients — gravity,... Read more »

Take a look around the Moon… no, really, take a good look AROUND the Moon! This is a fantastic animation of our planetary partner in space made by the folks on the Lunar Reconnaissance Orbiter team at Arizona State University. Assembled from reflectance maps and digital terrain models created from... Read more »

We’ve got two new podcasts from the Astronomy Cast team of Dr. Pamela Gay and Fraser Cain: Ep. 313: Precession, and Episode 314: Acceleration. 313: Precession The Earth is wobbling on its axis like a top. You can’t feel it, but it’s happening. And over long periods of time, these... Read more »

What’s new in the outer reaches of our solar system? Try the discovery of a Trojan asteroid orbiting Uranus. While a plethora of puns exist for this simple fact, the reality check is that this means there are far more of these objects out there than astronomers expected. The new... Read more »

Why don’t we have insects the size of horses? Why do bubbles form spheres? Why does it take so much energy to broadcast to every star? Let’s take a look at some non-linear mathematical relationships and see how they impact your day-to-day life. Click here to download the episode. Or... Read more »

Scientists have found answers to how a species' long-term adaptation to living in an extremely cold climate changes its social evolution. The post How did adaptations to living in cold climates favor social evolution? appeared first on Now Archaeology.... Read more »

The limestone slab, which resembled a toilet seat and had an access hole, was discovered in a home said to have belonged to a wealthy, high ranking family in a historic section of Jerusalem, Israel. The post Parasite filled poop found in a 2,500 year old luxury toilet appeared first... Read more »

An ancient quarry has been discovered in Malta in an area between Zejtun and Marsaxlokk. The post Ancient quarry discovered in Malta appeared first on Now Archaeology.... Read more »

Our species first appeared in Africa more than 300,000 years ago. The post Emergence of Homo sapiens in Africa appeared first on Now Archaeology.... Read more »

Scientists believe they have discovered the first evidence of wine consumption in the Americas on a Caribbean island. The post Oldest evidence of wine consumption in the Americas discovered appeared first on Now Archaeology.... Read more »

The writing on the little stone tablet discovered on Pilgrimage Road at the City of David site was possibly a receipt. The post 2,000 year old receipt found in Jerusalem appeared first on Now Archaeology.... Read more »

This study aimed to evaluate contrast-enhanced mammography (CEM) and to compare breast lesions on CEM and breast magnetic resonance imaging (MRI) using 5 features. We propose a flowchart for BI-RADS classification of breast lesions on CEM based on the Kaiser score (KS) flowchart for breast MRI. Sixty-eight subjects (women and... Read more »

Infrared small target detection is a crucial technology in both military and civilian applications, including surveillance, security, defense, and combat. However, accurate infrared detection of small targets in real-time is challenging due to their small size and similarity in gray level and texture with the surrounding environment, as well as...

Radish (Raphanus sativus) plants exhibit varied root colors due to the accumulation of chlorophylls and anthocyanins compounds that are beneficial for both human health and visual quality. The mechanisms of chlorophyll biosynthesis have been extensively studied in foliar tissues but remain largely unknown in other tissues. In this study, we... Read more »

Porosity in sintered materials negatively affects its fatigue properties. In investigating its influence, the application of numerical simulations reduces experimental testing, but they are computationally very expensive. In this work, the application of a relatively simple numerical phase-field (PF) model for fatigue fracture is proposed for estimation of the fatigue... Read more »

Polypeptoids are a family of synthetic peptidomimetic polymers featuring N-substituted polyglycine backbones with large chemical and structural diversity. Their synthetic accessibility, tunable property/functionality, and biological relevance make polypeptoids a promising platform for molecular biomimicry and various biotechnological applications. To gain insight into the relationship between the chemical structure, self-assembly behavior,... Read more »

An overwhelming number of people with HIV (PWH) experience chronic widespread pain (CWP) throughout their lifetimes. Previously, we demonstrated that PWH with CWP have increased hemolysis and attenuated heme oxygenase 1 (HO-1) levels. HO-1 degrades reactive, cell-free heme into antioxidants like biliverdin and carbon monoxide (CO). We found that high... Read more »

Objectives: The aims of the present study were two-fold: to investigate whether, compared to an active control condition, a modified mindfulness-based stress reduction (MBSR) program could (1) reduce symptoms of stress and depression, and (2) regulate salivary cortisol and serum creatine kinase (CK) concentrations, two physiological stress markers. Methods: Thirty... Read more »

Bamboo scrimber is widely used in interior decoration, architecture, and many other fields. However, it has caused huge security risks due to its inherent flammability and easy-to-produce toxic volatiles after combustion. In this work, the bamboo scrimber with superior flame retardant and smoke suppression properties was produced via the coupling... Read more »

Analyzing deep neural networks (DNNs) via information plane (IP) theory has gained tremendous attention recently to gain insight into, among others, DNNs’ generalization ability. However, it is by no means obvious how to estimate the mutual information (MI) between each hidden layer and the input/desired output to construct the IP.... Read more »

Positive displacement pumps are widely employed for their characteristics, but the pulsating flow they produce is a major and well-known drawback. To reduce the flow ripple produced by the pump, which in turn generates a pressure ripple, many methods have been investigated, from optimising the pump geometrical features to the... Read more »

Decoration of nanoparticles with specific molecules such as antibodies, peptides, and proteins that preserve their biological properties is essential for the recognition and internalization of their specific target cells. Inefficient preparation of such decorated nanoparticles leads to nonspecific interactions diverting them from their desired target. We report a simple two-step... Read more »

This paper presents a target tracking algorithm based on 4D millimeter-wave radar point cloud information for autonomous driving applications, which addresses the limitations of traditional 2 + 1D radar systems by using higher resolution target point cloud information that enables more accurate motion state estimation and target contour information. The... Read more »

Over a period of two years, this study analyzes the effect on food security of introducing new technologies through farmer field schools in the project “Adapting Agriculture and Livestock to Climate Change” (ACC). A household survey was conducted to compare 125 households in villages that were part of the project... Read more »

Cultural heritage is under tremendous pressure in the rapidly growing and transforming cities of the global south.
