Fake frogs in school dissections eliminate gross-out-factor
Sometimes it happens in middle school, sometimes in high school. The frogs are slimy and greenish-grey, and they stink because they're pickled in formaldehyde. One Florida high school recently tried to eliminate the gross-out factor by using fake, yet highly realistic,...
Earthshot Prize: William and Kate launch prize to 'repair the Earth'
The Duke and Duchess of Cambridge unveil a global prize to tackle climate issues in the next decade.
Giant magnetic ropes seen in Whale Galaxy's halo
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.
Plants model more efficient thermal cooling method
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.
New cultures, new experiences: 4 ways to keep kids learning while travelling
The school year is over and holidays are upon us. But that doesn't mean your children's learning experiences can't continue.
Let it breed: why desexing dogs isn't always the best thing to do
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.
Hot and bothered: heat affects all of us, but older people face the highest health risks
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.
Wildfire modeling helps predict fires in Colombia
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.
New study reveals higher microplastics in London air compared to other cities
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.
Image: Hubble views a galaxy with an active center
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.
Rewriting quantum mechanics in their spare time
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".
Simulations show thousands of lakes in Himalaya Mountains at risk of flooding due to global warming
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.
York to ban cars from city centre
The measure would ban all "non-essential" private car journeys in the city centre by 2023.

Prince William launches Earthshot Prize for innovations in solving environmental challenges
Prince William is collaborating with a global alliance of groups to launch a prize geared toward fostering innovation to combat climate change and solve environment...
Sleeping too long or not enough linked to pulmonary fibrosis: new study
New UK research suggests that people who regularly sleep too little or too much are more likely to have pulmonary fibrosis, compared to those who sleep the recommended seven hours a night. The study, by researchers at the University of Manchester, looked at 500,074 participants taking part in the long-term UK Biobank study, which includes genomic data on more than half a million UK residents....
Skomer Island managers seek 'fit and hardy' staff
The Wildlife Trust is looking to recruit a deputy warden and a visitor officer to work on the island.
Nearly quantized conductance plateau of vortex mode in an iron-based superconductor
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...
Extending El Niño event predictions to a year
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...
Radiophysicists study the properties of composites for 5G devices
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.
Wind conditions influence water circulation and carbon dioxide concentrations in the Southern Ocean
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...
Biologists use the Aeroschup to clean plastic from water
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.
How nanoparticles from the environment enter the brain
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...
Student creates a spray for flash disinfecting of institutions
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.
