The Silver Institute highlighted some of the advancements using silver in the latest edition of Silver News.Silver nanoparticles can apparently kill biting midges without the use of harsh pesticides. Biting midges are tiny flying insects that spread
As celestial entities go, black holes are, paradoxically, both commonplace and extraordinary. They could be seen as commonplace due to their general ubiquity. Astrophysicists now believe that giant black holes ?" each with the mass of millions or b
Changing the way numbers are stored in computers could improve the accuracy of calculations without needing to increase energy consumption or computing power, which could prove useful for software that needs to quickly switch between very large and s
There is one argument against the claim that the distribution of intelligence is different by race or gender that I have very rarely seen and have not discussed here ?" the claim that since there is no advantage to being stupid there is no reason w
Bohr had electrified the scientific world in 1913 with his bold theory of how atoms are constituted. Drawing on an idea proposed in 1900 by the German physicist Max Planck, he said that the electrons that orbit the dense central nucleus are constra
Here is a 3 minute clip showing the voltage that can be created by spinning mercury. All the pyramids with pools of mercury under them seem to ring a bell….
But in 1912, Austrian-American physicist Victor Hess measured the ambient radiation level in a high-altitude balloon and discovered it was much higher than at ground level, even during an eclipse when the Sun was blocked. This meant the radiation had
One summer afternoon, there had been a rain shower that left the air fresh. I looked at the clouds and saw a rainbow strangely close by. I followed its arc and to my amazement, the rainbow came down nearby. I headed toward the floating colors. They w
We learn in grade school that water freezes at zero degrees Celsius, but that's seldom true. In clouds, scientists have found supercooled water droplets as chilly as minus 40 C, and in a lab in 2014, they cooled water to a staggering minus 46 C bef
Quasars are among the brightest objects in the Universe. They are galaxies in which the supermassive black hole is feeding at a tremendous rate: a gargantuan cloud of dust and gas surrounds it, from which the black hole therein is positively guzzling
"The structure of the brain at the cellular level appears to be near a phase transition," said Northwestern's Helen Ansell, the first author of a paper about the finding. "An everyday example of this is when ice melts into water. It's still wate
In general relativity, time is baked into the fabric of the universe - our physical reality is set in space-time. Under this theory, time can warp and dilate in the presence of gravity. But quantum theory treats time as something that is not mall
Similarly, in one paper, an ant colony was bizarrely rebranded as an "underground creepy crawly state." The misuse of terminology extends to machine learning, where a 'random forest' is whimsically translated to 'irregular backwoods' or 'ar
It turns out that the ineffective COVID shots were just the beginning. As far as we know and have discovered in the course of investigations, the shot was developed quickly as a countermeasure to distract from the problem of a lab leak. The world's
The research, performed at the National University of Singapore's Cancer Science Institute of Singapore, and led by professor Ashok Venkitaraman and Li Ren Kong, a senior research fellow at the University of Singapore, found a chemical released whe
The brain is complex; in humans it consists of about 100 billion neurons, making on the order of 100 trillion connections. It is often compared with another complex system that has enormous problem-solving power: the digital computer. Both the brain
Despite an ever-growing body of evidence indicating we're now living beneath unprecedented levels of atmospheric greenhouse gases, a lack of thorough historical knowledge has hindered our ability to put present-day CO2 emissions into a concrete, long
He just seems so convinced that he's right. And that he is about to change the world.
The sun's magnetic engine, called the solar dynamo, lies about 200,000 kilometers beneath the sun's surface. As it churns, that engine drives solar activity, which waxes and wanes over periods of roughly 11 years. When the sun is more active, sol
The Eta Aquariids, slated to be one of the best meteor showers during 2024, have begun. The Eta Aquariid meteor shower runs from April 15 through May 27, peaking on the night of May 4-5.
The EHang EH216-S autonomous flying taxi is the first eVTOL ready for mass production and could lead the way for flying cars around the world.
A 2023 study found that olivine sand deployed across the oceans would mostly sink into the depths before it could raise pH. Yool and Palmiéri modelled an alternative scenario, in which the olivine would be spread over coastal shelves less than 100
In 1978 a chess engine named Belle won the North American Computer Chess Championship run by the Association for Computing Machinery, the engine's special hardware allowed it to analyze around thirty million positions in three minutes. Belle also h
