Scientists have created thin films made from barium zirconium sulfide (BaZrS3) and confirmed that the materials have alluring electronic and optical properties predicted by theorists.
The deaf community risks being excluded from aspects of modern science because the number of new advances is outpacing the development of sign language to explain them, a leading researcher says.
For the first time, LEGO ® has been cooled to the lowest temperature possible in an experiment which reveals a new use for the popular toy -- the development of quantum computing. A figure and four blocks were placed inside the most effective refrigerator in the world, capable of reaching 1.6 millidegrees above absolute zero (minus 273.15 Centigrade), which is about 200,000 times colder than room...
Artificial intelligence can detect one of the most common forms of blood cancer - acute myeloid leukemia -- with high reliability. Researchers at the DZNE and the University of Bonn have now shown this in a proof-of-concept study. Their approach is based on the analysis of the gene activity of cells found in the blood. Used in practice, this approach could support conventional diagnostics and...
Researchers developed a liquid electret material capable of semi-permanently retaining static electricity. They subsequently combined this material with soft electrodes to create the first bendable, stretchable vibration-powered device in the world. Because this device is highly deformable and capable of converting very subtle vibrations into electrical signals, it may be applicable to the...
Researchers investigated the science behind the formation of the 'V' patterns -- also known as chevron patterns -- in the swimming muscles of fish. The study focused on the myotome (a group of muscles served by a spinal nerve root) that makes up most of the fish body. The research team found that these patterns do not simply arise from genetic instruction or biochemical pathways but actually...
Neurochemicals such as serotonin and dopamine play crucial roles in cognitive and emotional functions of our brain. Vesicular monoamine transporter 1 (VMAT1) is one of the genes responsible for transporting neurotransmitters and regulating neuronal signaling. A research team has reconstructed ancestral VMAT1 proteins, revealing the functional changes in neurotransmitter uptake of VMAT1 throughout...
,Over the past few years, a variety of laws have been enacted in New York State and New York City as we accelerate our transition to a more efficient and decarbonized energy system. One new rule that is bound to attract attention is a new system of grading and then displaying the energy efficiency rating of large buildings. Just as restaurants must display the grade they receive evaluating the...
Around mid- to late summer, Adam Downing started receiving about double the number of calls he usually does about oak trees dying.
New evidence of a massive lightning strike at the center of a hidden stone circle in the Outer Hebrides may help shed light on why these monuments were created thousands of years ago.
Twin stars appear to share chemical "DNA" that could help scientists map the history of the Milky Way galaxy, according to new research by astronomer Keith Hawkins of The University of Texas at Austin accepted for publication in The Monthly Notices of the Royal Astronomical Society.
In physics, non-Hermitian systems are systems that cannot be described by standard (i.e., Hermitian) laws of quantum mechanics, or more precisely, that can only be described by non-Hermitian Hamiltonians. Non-Hermitian systems are ubiquitous in nature. Many open systems, i.e., systems that are not fully isolated from the rest of the world, belong to this class. The topology of these systems (i.e.,...
Recent advances in smart contact lenses can assist biomedical engineers to realize medical applications and vision imaging for augmented reality with wireless communication systems. Previous research on smart contact lenses were driven by a wireless system or wireless power transfer with temporal and spatial restrictions. Such power sources can limit their continuous use and require energy storage...
The critical tipping point for the Amazon rainforest has arrived, and an ecological disaster could be in the making if drastic actions aren't taken immediately.
Sex is an ancient and widespread phenomenon, with over 99 percent of eukaryotes (cells with nuclei) partaking in some form of sexual reproduction, at least occasionally. Given the relative ubiquity and presumed importance of sex, it is perhaps surprising that the mechanisms that determine an individual's sex vary so spectacularly across organisms. Mechanisms for sex determination can depend on...
A chemist from RUDN University has synthesized new types of optically active materials with the structure of the mineral perovskite. He proposed an environmentally friendly, fast, and easily reproducible mechanochemical method, which allows obtaining hybrid materials of high purity, promising for the creation of solar cells. The article was published in the journal Nanoscale.
British sign language is receiving an astronomical update thanks to a unique collaboration between a space scientist and a group of deaf astronomers.
The last 12 months have felt chaotic, destabilizing, and on occasion apocalyptic. Toxic nationalist movements have risen across the globe; politics in democratic nations have increasingly polarized; wealth gaps continue to expand; and the specter of climate change lurking at a remove has become an actual monster inside the house. It’s difficult, in the context…
Arguments over whether game addiction is real have led to feuds between government departments and a national debate over policy.
The discovery was made by scientists at a 4,000-year-old archaeological site in the Hebrides.
Autopilot run amok, bogus agriculture bots, and genetic gaydar all made our list of the worst technologies of the year.
Poll after poll shows that people now want action. But at the international level progress is being deliberately stymiedIn 1988, Time magazine selected “The Endangered Earth” as its person of the year. This December, 31 years later, the honour went to Greta Thunberg. The point of the Time exercise is to take a complex issue and locate a person through whom we can better understand it. Twenty...
Managed properly, dwarf mistletoe is a normal, even healthy part of B.C.'s forest ecosystem, but improper management and natural disasters can clear the way for infestations that stunt fledgling trees and wreck up to 40 per cent of the volume — and profitability — of a...
The amount of food needed to feed the world's population by the end of the century could increase by almost 80%, a study suggests.
Grown together, newly examined 'lost crops' could have produced enough seed to feed as many indigenous people as traditionally grown maize, according to new research from Washington University in St. Louis.
