Active galactic nuclei (AGN) are supermassive black holes at the centers of galaxies that are accreting material. These AGN emit jets of charged particles that move at speeds close to that of light, transporting huge amounts of energy away from the central black hole region and radiating across the electromagnetic spectrum. Blazars are extreme examples of AGN in which the collimated jets are...

A firefighter says asbestos, mold and toxic fumes inside a fire station in Alabama's largest city have sickened him and other firefighters.

Egypt's recent decision to transport ancient Pharaonic artifacts to a traffic circle in the congested heart of Cairo has fueled fresh controversy over the government's handling of its archaeological heritage.

Tiny bits of DNA collected from waters off the West Coast allowed scientists to identify more species of marine vertebrates than traditional surveys with trawl nets. They also reflect environmental shifts such as unusual ocean temperatures that affect the organisms present, new research shows.

Visible imagery from NASA's Aqua satellite on Dec. 31 revealed that Tropical Cyclone Calvinia had moved south of the island of Mauritius in the Southern Indian Ocean.

NASA-NOAA's Suomi NPP satellite provided forecasters with an image of Tropical Cyclone Sarai and it showed a much weaker storm near Tonga in the South Pacific Ocean.

Using the National Science Foundation's Karl G. Jansky Very Large Array radio telescope, a team of astronomers has captured for the first time an image of large-scale, coherent, magnetic fields in the halo of a faraway spiral galaxy, confirming theoretical modeling of how galaxies generate magnetic fields and potentially increasing knowledge of how galaxies form and evolve.

When drops of water touch the surface of a lotus flower leaf, they form beads and roll off, collecting dust particles along the way. In contrast, water droplets on a rose petal also form beads, but remain pinned to the petal's surface. A mechanical engineer at Washington University in St. Louis combined the two concepts to find a more efficient way for droplets to evaporate from a surface.

The school year is over and holidays are upon us. But that doesn't mean your children's learning experiences can't continue.

In pet-loving nations such as Australia, nobody likes the idea of dogs churning out litters in squalid conditions or sitting homeless in a shelter.

Australian summer temperatures have risen by 1.66℃ over the past 20 years. In the past century we've seen a significant increase in the number, intensity and duration of heatwaves during our summers.

A new wildfire model helps predict where and when wildfires will start in the Aburrá Valley of Colombia. This research, presented earlier this month at the 2019 American Geophysical Union Fall Meeting in San Francisco, is helping local cities avoid the devastating environmental and health impacts of fires.

Researchers from King's have carried out the first study of microplastics in the atmosphere in London to determine what people within the city might be exposed to and where this comes from.

This swirling mass of celestial gas, dust and stars is a moderately luminous spiral galaxy named ESO 021-G004, located just under 130 million light-years away.

As students, Jussi Lindgren and Jukka Liukkonen had found one element of their quantum mechanics lectures unsatisfying. "When we were taught physics, there were some fundamental elements you were told were true, and you had to accept they were true without it being shown why," said Jussi Lindgren, "and I didn't really like this".

Three researchers with the University of Potsdam report that thousands of natural lakes in the Himalayas are at risk of bursting their moraines due to global warming and causing flooding downriver. In their paper published in Proceedings of the National Academy of Sciences, Georg Veh, Oliver Korup and Ariane Walz describe simulations they ran on lake models and what they showed.

When a semiconducting nanowire is coupled to a superconductor, it can be tuned to topological quantum states thought to host localized quasiparticles known as Majorana Zero Modes (MZM). MZMs are their own antiparticles, with promising applications in topological quantum computing. Due to particle-antiparticle equivalence, MZMs exhibit quantized conductance at low temperatures. While many...

A group of researchers from the Potsdam Institute for Climate Impact Research, Beijing Normal University and Justus-Liebig-Universität Giessen has found a way to predict El Niño events up to a year before they occur. In their paper published in the Proceedings of the National Academy of Sciences, the group describes their complexity-based approach to better predicting the seemingly random...

TSU radiophysicists are forming a database of properties of composite materials that can be used to create 5G and space communication devices operating in the terahertz range. The scientists are creating composite materials from ABS plastic and nanotubes and measuring their properties in a frequency range from 10 MHz to 1 THz.

The sea encircling Antarctica acts as a huge mixer for water from all the ocean basins—and this circulating pattern influences the exchange of carbon dioxide (CO2) between the ocean and the atmosphere. A study by an international team of researchers led by Dr. Torben Struve from the University of Oldenburg's Institute for Chemistry and Biology of the Marine Environment (ICBM) has now established...

The Aeroschup technology created by TSU biologists to clean petroleum products from the bottom of reservoirs will be used to solve the problem of plastic contamination. The project team has already completed laboratory tests that confirmed the ability of the Aeroschup to extract plastic particles from bottom sediments. The team plans to conduct field tests of the technology in the summer of 2020.

A group of scientists from the Russian Academy of Sciences (ICG SB RAS) and the TSU Biological Institute has established a path through which nanoparticles of viruses and organic and inorganic substances from the environment enter the brain. Additionally, the researchers report a simple and inexpensive way to block their entry. The data obtained by the project could play a large role in medicine...

Alexander Buzaev, a young scientist at the TSU Faculty of Chemistry, is developing a photocatalytic coating for disinfecting indoor surfaces in hospitals, schools, kindergartens, and other institutions. The substance, which forms a very thin film without color or odor, could be used to protect against bacteria.

Thousands of holidaymakers and locals were forced to flee to beaches in fire-ravaged southeast Australia Tuesday, as blazes ripped through popular tourist areas leaving no escape by land.
