A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary stars, usually referred to as wide binaries in astronomy and astrophysics. The study carried out by Kyu-Hyun Chae, professor of physics and astronomy at Sejong Read more about Gravity Changes how it works at low acceleration shown by observations of widely seperated binary stars[…]

A team from the University of Chicago has announced the first evidence for “quantum superchemistry”—a phenomenon where particles in the same quantum state undergo collective accelerated reactions. The effect had been predicted, but never observed in the laboratory. […] Chin’s group is experienced with herding atoms into quantum states, but molecules are larger and much Read more about Scientists observe first evidence of ‘quantum superchemistry’ in the laboratory[…]

Scientists have combined two light wavelengths to deactivate a bacterium that is invulnerable to some of the world’s most widely used antibiotics, giving hope that the regime could be adapted as a potential disinfectant treatment. Under the guidance of project leader Dr. Gale Brightwell, scientists at New Zealand’s AgResearch demonstrated the novel antimicrobial efficiency of Read more about Dual wavelengths of light shown to be effective against antibiotic-resistant superbug bacterium[…]

The team at NASA made three animations, all showing the carbon dioxide levels throughout the year 2021. Each one shows four major contributors: fossil fuels, burning biomass, land ecosystems, and the oceans. In the view showing North and South America, we can see the results of plants absorbing the gas via photosynthesis and then releasing Read more about Animation Shows What the World Would Look Like If You Could See Carbon Dioxide Emissions[…]

A new study examining the effects of planting a wildflower meadow in the historic grounds of King’s College, Cambridge, has demonstrated its benefits to local biodiversity and climate change mitigation.   The study, led by King’s Research Fellow Dr. Cicely Marshall, found that establishing the meadow had made a considerable impact to the wildlife value Read more about Establishing a wildflower meadow bolstered biodiversity and reduced greenhouse gas emissions, study finds[…]

Brain signals can be used to detect how much pain a person is experiencing, which could overhaul how we treat certain chronic pain conditions, a new study has suggested. The research, published in Nature Neuroscience today, is the first time a human’s chronic-pain-related brain signals have been recorded. It could aid the development of personalized Read more about Brain waves can tell us how much pain someone is in[…]

Research has shown that a thin cellulose film can inactivate the SARS-CoV-2 virus within minutes, inhibit the growth of bacteria including E. coli, and mitigate contact transfer of pathogens. The coating consists of a thin film of cellulose fiber that is invisible to the naked eye, and is abrasion-resistant under dry conditions, making it suitable Read more about The ‘invisible’ cellulose coatings that mitigate surface transmission of pathogens (kills covid on door handles)[…]

Finding, cultivating, and bioengineering organisms that can digest plastic not only aids in the removal of pollution, but is now also big business. Several microorganisms that can do this have already been found, but when their enzymes that make this possible are applied at an industrial scale, they typically only work at temperatures above 30°C. Read more about Scientists discover microbes in the Alps and Arctic that can digest plastic at low temperatures[…]

[…] an alarming new study has found that even when plastic makes it to a recycling center, it can still end up splintering into smaller bits that contaminate the air and water. This pilot study focused on a single new facility where plastics are sorted, shredded, and melted down into pellets. Along the way, the Read more about Yet another problem with recycling: It spews microplastics[…]

[…] a team of researchers from the École Polytechnique Fédérale de Lausanne (EPFL) successfully developed a machine-learning algorithm that can decode a mouse’s brain signals and reproduce images of what it’s seeing. […] The mice were shown a black and white movie clip from the 1960s of a man running to a car and then Read more about Researchers See Through a Mouse’s Eyes by Decoding Brain Signals[…]

[…] Toucan, a browser extension, is trying a different approach, and it might just be the thing that finally clicks for you. How Toucan works With Toucan installed for either Chrome, Edge, or Safari, the first time you visit a website or click on an article, you’ll notice something strange: Some of the words on the Read more about Toucan Teaches You a New Language While You Browse the Internet[…]

An anonymous reader quotes a report from Reuters: Researchers said on Wednesday they have discovered that parts of the brain region called the motor cortex that govern body movement are connected with a network involved in thinking, planning, mental arousal, pain, and control of internal organs, as well as functions such as blood pressure and Read more about Scientists Identify Mind-Body Nexus In Human Brain[…]

A survey of plastic waste picked up in the North Pacific Subtropical Gyre—aka the Giant Pacific Garbage Patch—has revealed that the garbage is providing a home to species that would otherwise not be found in the deep ocean. Over two-thirds of the trash examined plays host to coastal marine species, many of which are clearly Read more about Pacific garbage patch providing a deep ocean home for coastal species[…]

[…] Debashis Chanda, a nanoscience researcher with the University of Central Florida, and his team have created a way to mimic nature’s ability to reflect light and create beautifully vivid color without absorbing any heat like traditional pigments do. Chanda’s research, published in the journal Science Advances, explains and explores structural color and how people Read more about Scientists create structural paint that stays cool underneath, doesn’t fade, extremely light and no toxins[…]

Scientists using data from the Atacama Cosmology Telescope in Chile have made a detailed map of dark matter’s distribution across a quarter of the sky. The map shows regions the distribution of mass extending essentially as far we can see back in time; it uses the cosmic microwave background as a backdrop for the dark Read more about New Map of Dark Matter Supports Einstein’s Theory of Gravity[…]

Researchers have discovered that in the exotic conditions of the early universe, waves of gravity may have shaken space-time so hard that they spontaneously created radiation. […] a team of researchers have discovered that an exotic form of parametric resonance may have even occurred in the extremely early universe. Perhaps the most dramatic event to Read more about Physicists Discover that Gravity Can Create Light[…]

The experiment relies on materials that can change their optical properties in fractions of a second, which could be used in new technologies or to explore fundamental questions in physics. The original double-slit experiment, performed in 1801 by Thomas Young at the Royal Institution, showed that light acts as a wave. Further experiments, however, showed Read more about Double-slit experiment done using time instead of space[…]

What does a stressed plant sound like? A bit like bubble-wrap being popped. Researchers in Israel report in the journal Cell on March 30 that tomato and tobacco plants that are stressed—from dehydration or having their stems severed—emit sounds that are comparable in volume to normal human conversation. The frequency of these noises is too Read more about Stressed plants emit airborne sounds that can be detected from more than a meter away[…]
