Powerful telescopes like NASA’s Hubble, James Webb, and Chandra X-ray Observatory provide scientists a window into deep space to probe the physics of black holes. While one might wonder how you can “see” a black hole, which famously absorbs all light, this is made possible by tidal disruption events (TDEs) - where a star is destroyed by a supermassive black hole and can fuel a “luminous accretion flare.” With luminosities thousands of billions of times brighter than the Sun, accretion events enable astrophysicists to study supermassive black holes (SMBHs) at cosmological distances. TDEs occur when a star is violently ripped ...

As a frontier research area, LLPS plays a significant role in cancer through its regulation of multiple facets, including signaling pathways, gene expression, and tumor microenvironment. Dysregulation of LLPS leads to the formation of various aggregates, such as amyloid proteins, suggesting that modulating LLPS in ...

The brain is responsible for the "general command" of human thinking and coordination of the body. Thus, various brain diseases can cause great damage to the human body and nervous system. Brain tumors are caused by abnormal cells that grow and multiply irregularly within the brain. Glioma is one of the most common malignant tumors in adults. It originates from glial cells and the surrounding infiltrating tissue, compresses other normal tissues in the brain during the growth process, and blurs the boundary of the tumor. ...

Understanding how cells move and behave can lead to breakthroughs in treating diseases, developing new drugs, and creating innovative therapies. For example, in cancer research, tracking how cancer cells migrate can reveal how tumors grow and spread through the human body. This insight can led to the discovery of more efficient and targeted treatments to stop or even prevent metastasis. Scientists have introduced CellTracksColab, a tool that simplifies cell tracking data analysis. This free platform leverages advanced ...

Researchers at Utrecht University in the Netherlands have identified a new way in which the toxic protein aggregates associated with Huntington’s disease may damage nerve cells and cause them to die. The study, to be published August 16 in the Journal of Cell Biology (JCB), suggests that the aggregates can poke holes in the membrane that separates the nucleus from the rest of the cell, damaging the DNA inside the nucleus and changing the activity of neuronal genes. Huntington’s disease is a devastating neurogenerative disorder caused by a mutation in the HTT gene that results in cells producing abnormally large versions of the huntingtin protein. These ...

The Colorado River and its tributaries provide water for hydropower, irrigation and drinking water in seven U.S. states and Mexico. Much of this water comes from the snowpack that builds up over the winter and then melts each spring. Every year in early April, water managers use the snowpack to predict how much water will be available for the upcoming year. But since 2000, these predictions have been incorrect, with the actual streamflow being consistently lower than the predicted streamflow. That’s left water managers ...

On May 11, a gorgeous aurora surprised stargazers across the southern United States. That same weekend, a tractor guided by GPS missed its mark. What do the visibility of the northern lights have in common with compromised farming equipment in the Midwest? A uniquely powerful geomagnetic storm, according to two newly published papers co-authored by Virginia Tech's Scott England. “The northern lights are caused by energetic, charged particles hitting our upper atmosphere, which are impacted by numerous factors in space, including the sun,” said England, associate professor in the Kevin T. Crofton Department of Aerospace and Ocean Engineering. “During ...

COLUMBUS, Ohio – A new national study provides the best evidence to date that generous unemployment insurance benefits during the COVID-19 pandemic helped reduce reliance on high-cost credit use.   Researchers found that lower-income residents of states with more generous benefits were significantly less likely than those living in less-generous states to take out new credit cards, personal finance loans and payday loans or other alternative financial service offerings.   The study, published recently in the journal ...

With new medications on the market or in the works for Alzheimer’s disease and other kinds of dementia, a new study suggests that getting the diagnosis needed to access these new treatments may depend on where you live.  The percentage of people who get a new dementia diagnosis each year varies a lot across regions of the U.S., the study finds. And the differences between regions of the country are even larger for people on the young end of the dementia-risk age range, ages 66 to 74, and for those who are Black ...

Barely audible to human ears, healthy soils produce a cacophony of sounds in many forms – a bit like an  underground rave concert of bubble pops and clicks. Special recordings made by Flinders University ecologists in Australia show this chaotic mixture of soundscapes can be a measure of the diversity of tiny living animals in the soil, which create sounds as they move and interact with their environment. With 75% of the world’s soils degraded, the future of the teeming community of living species that live underground face a dire future without restoration, says microbial ecologist Dr Jake Robinson, from the Frontiers ...

COLUMBUS, Ohio (August 16, 2024) – Building positive connections with teachers and peers in the classroom can be critical to the mental health and academic success of children and adolescents.

People who are homeless often endure constant and intrusive police interactions, leaving them feeling intimidated, harassed and stigmatised, a new study finds. More people of all ages and backgrounds are finding themselves homeless, often due to job loss or illness, as well as a lack of affordable housing. Between 2016 and 2021 homelessness increased by 5.2% in Australia.  Professor of Law Thalia Anthony from the University of Technology Sydney (UTS) said the research aimed to give a voice to people experiencing homelessness ...

A rock formation spanning Ireland and Scotland may be the world’s most complete record of “snowball Earth”, a crucial moment in planetary history when the globe was covered in ice, finds a new study led by UCL (University College London) researchers. The study, published in the Journal of the Geological Society of London, found that the Port Askaig Formation, composed of layers of rock up to 1.1km thick, was likely laid down between 662 to 720 million years ago during the Sturtian glaciation – the first of two global freezes thought to have ...

Thomas Edison went through thousands of materials before he finally found the right tungsten filament to create a working lightbulb. This type of trial-and-error research continues today and is responsible for countless inventions that improve our world. Battery systems that help power our lives in many seen (and unseen) ways are one example. However, improving these materials and devices requires more than experimentation. Modern engineers must also form a deeper understanding of the general principles that govern material performance, from which they can design better materials to achieve challenging product requirements.  In a paper ...

New Haven, Conn. — In humans, the process of learning is driven by different groups of cells in the brain firing together. For instance, when the neurons associated with the process of recognizing a dog begin to fire in a coordinated manner in response to the cells that encode the features of a dog — four legs, fur, a tail, etc. — a young child will eventually be able to identify dogs going forward. But brain wiring begins before humans are born, before they have experiences or senses like sight to guide this cellular circuitry. How does that happen? In a new ...
