Just as the sun has planets and the planets have moons, our galaxy has satellite galaxies, and some of those might have smaller satellite galaxies of their own. To wit, the Large Magellanic Cloud (LMC), a relatively large satellite galaxy visible from the Southern Hemisphere, is thought to have brought at least six of its own satellite galaxies with it when it first approached the Milky Way, based on recent measurements from the European Space Agency's Gaia mission.

A new therapy could combat persistent joint infections in horses, potentially saving them from years of pain. Morris Animal Foundation-funded researchers at North Carolina State University have developed a platelet-rich plasma (PRP) lysate that, when teamed with antibiotics, can eradicate bacterial biofilms common in joint infections. The therapy could also be applied to other species, including humans and dogs.

Using a modified natural substance along with current approaches could improve colon cancer treatment, according to findings by University of California, Irvine biologists. The discovery comes from their research into the role of an amino acid in tumor development and a potential method for reversing the process. Their paper appears in Nature Cancer. The disease is the second-leading cause of cancer-related deaths in the United States.

The Casimir Force is a well-known effect originating from the quantum fluctuation of electromagnetic fields in a vacuum. Now an international group of researchers have reported a counterpoint to that theory, adding to the understanding of energy fluctuations within fluids.

It is clear that we must prioritize identifying and alleviating the conditions that made the Covid-19 pandemic possible. Even as it rages, scientists are already asking if it is more than just a virus, but rather a symptom emerging from something much deeper, a nonlinear dynamical system of coupled pathologies underlying a veneer of "progress" in an increasingly fragile, volatile, hyperconnected world.

Hospitals can prepare for a surge of patients critically ill with COVID-19, but it will require hospital leaders, practitioners and regional officials to adopt drastic measures that challenge the standard way of providing care, according to a new RAND Corporation report.

Some substances are known to exist in several different structurally disordered solid states, a phenomenon known as polyamorphism.

The first and perhaps most celebrated example of polyamorphic behavior was discovered in water ice in 1984 by Mishima et al. Two different forms of amorphous water ice were identified, known as low-density amorphous and high-density amorphous ices. Later on, similar phenomena were also observed in other important systems such as Si, SiO2, and GeO2.

Researchers have shown how a by-product of steel making can be used to both treat wastewater and make stronger concrete, in a zero-waste approach to help advance the circular economy.

Produced during the separation of molten steel from impurities, steel slag is often used as a substitute aggregate material for making concrete.

Steel slag can also be used to absorb contaminants like phosphate, magnesium, iron, calcium, silica and aluminium in the wastewater treatment process, but loses its effectiveness over time.

Before there were farms in southwest Michigan, there were prairies. For thousands of years, tall grass prairies stood undisturbed until European settlers turned the rich, highly productive soils to agriculture.

Today, tall grass prairies East of the Mississippi are virtually extinct.

But some landowners want to return land throughout the Midwest to its incredibly deep roots, converting abandoned, depleted and fallow agricultural fields to native prairie--with varying degrees of success.

Researchers have observed directly and for the first time magnetoacoustic waves (sound-driven spin waves), which are considered as potential information carriers for novel computation schemes. These waves have been generated and observed on hybrid magnetic/piezoelectric devices. The experiments were designed by a collaboration between the University of Barcelona (UB), the Institute of Materials Science of Barcelona (ICMAB-CSIC) and the ALBA Synchrotron. The results show that magnetoacoustic waves can travel over long distances -up to centimeters- and have larger amplitudes than expected.

When the brain gets injured, star-shaped brain cells called astrocytes come to the rescue. In the case of glioma - the most common type of primary brain tumor - this protective action comes at a price.

New research led by hearing scientists at Oregon Health & Science University suggests an avenue to treat and prevent intractable genetic disorders before birth.

Researchers at the Oregon Hearing Research Center, working with mice, injected a specially designed synthetic molecule into the developing inner ear of fetal mice 12 days after fertilization. The study found that the technique corrected the expression of a mutated gene that causes Usher syndrome, a disorder characterized by deafness and progressive vision loss affecting an estimated 4 to 17 of every 100,000 people.

As a Yale University postdoctoral researcher, economist Jude Bayham studied the potential consequences of a global pandemic that could shutter schools, close businesses, and strain hospitals. That was back in 2013.

Now, as the world grapples with the coronavirus, the Colorado State University economist and a multi-institutional team are turning those prescient modeling exercises into real insights for policymakers.

A protein called phytochrome B, which can sense light and temperature, triggers plant growth and controls flowering time. How it does so is not fully understood.

A sponge found in Manado Bay, Indonesia, makes a molecule called manzamine A, which stops the growth of cervical cancer cells, according to a recent publication in the Journal of Natural Products submitted by researchers at the Medical University of South Carolina (MUSC) and their collaborators. Collaborators include students and investigators at the University of South Carolina (UofSC), College of Charleston, Gadjah Mada University in Indonesia and the University of Malaya in Malaysia.
