Demand for food-bearing labels like ‘organic’ or ‘sustainable’ is soaring, but some growers question whether the name is really worth the pain. While some industry groups say that labels help consumers make choices, and getting the right credentials can offer manufacturers a valuable point of difference, others worry that the labels present a barrier to those wishing to adopt some of the practices associated with them. Consumers push the urge, but when they buy organic, natural, regenerative or conventional agricultural products, do they really know what that means? Stay out of the label box Labels such as “certified organic” require farmers to meet certain production standards, which can limit chemical use and regulate farm management. Herders Peter and Nikki Thompson use mostly natural practices such as multi-species planting and reduced input use on their 4,000 hectare Echo Hills property, 80 kilometers northeast of Rome in Queensland. But they haven’t found a label that reflects th

Specifically, the Antipas team used their experiments to search for a class of dark matter known as ultralight dark matter. At their heaviest, ultra-bright dark matter particles are still about a trillion times lighter than electrons. According to quantum mechanics, all matter has both particle-like and wave-like qualities, with larger objects typically having more particle-like qualities and smaller ones having more wave-like qualities. “When people talk about ultra-bright dark matter, they mean that dark matter is more like a wave,” said physicist Kathryn Zurek of the California Institute of Technology, who was not involved in the experiment. Like all other dark matter experiments so far, the Antipas search has found nothing. However, the absence of their discovery helps limit the properties of dark matter, as experiments show what dark matter is not. Also, the team’s approach differs from that of the more famous dark matter experiment, which looks for particles known as WIMPs (

Researchers have just studied the oldest lensing of light we can see and found the oldest dark matter ever observed, around a galaxy 12 billion years old. They spotted this dark matter by looking at how some galaxies bend the cosmic microwave background light, the earliest detectable radiation after the Big Bang, that rocked the universe as we know it. The team’s research is published in Physical Review Letters. “Most researchers use source galaxies to measure the distribution of dark matter from now to eight billion years ago,” said Yuichi Harikane, astronomer at the Institute for Cosmic Ray Research at the University of Tokyo and co-author of a recent paper, in a Nagoya University release. . “However, we were able to look further into the past because we used the CMB further afield to measure dark matter. For the first time, we’re measuring dark matter almost from the early days of the universe.” Dark matter makes up about 27% of the universe, although we cannot detect it directly

In a former gold mine a mile underground, inside a titanium tank filled with a rare liquefied gas, scientists have begun a search for what so far has not been able to find: dark matter. Scientists are pretty sure invisible objects make up most of the mass of the universe and say we wouldn’t be here without them – but they don’t know what they are. The race to solve this great mystery has taken one team to the depths beneath Lead, South Dakota. The question for scientists is basic, says Kevin Lesko, a physicist at Lawrence Berkeley National Laboratory. “What is this great place I live in? Right now, 95% of it is a mystery.” The idea is that a mile of dirt and rock, a giant tank, a second tank, and the world’s purest titanium will block out nearly all of the cosmic rays and particles that glide around – and penetrate – all of us every day. But dark matter particles, scientists say, can avoid all those obstacles. They hoped someone would fly into a vat of liquid xenon in the inner

Australian scientists are making strides to solve one of the universe’s greatest mysteries: the invisible nature of “dark matter”. The ORGAN Experiment, Australia’s first major dark matter detector, recently completed the search for a hypothetical particle called an axion — a popular candidate among theories trying to explain dark matter. ORGAN has placed new limits on the possible characteristics of axions and thus helped to narrow their search. But before we get ahead of ourselves… Let’s start with a story About 14 billion years ago, all the tiny bits of matter – the fundamental particles that would later become you, the planets and galaxies – were compressed into one very dense and hot region. Then the Big Bang happened and everything flew apart. Particles combine to form atoms, which eventually clump together into stars, which explode and create all kinds of exotic matter. After a few billion years came the Earth, which finally crawled on the little things called humans. Cool st

Physicists have created an extraordinary phase of matter never seen before in a quantum computer. Physicists demonstrate a less error-prone way of storing quantum information by subjecting quantum computer qubits to quasi-rhythmic laser pulses based on the Fibonacci sequence. Physicists have created an extraordinary, never-before-seen phase of matter by shining a sequence of laser pulses inspired by the Fibonacci sequence on atoms inside a quantum computer. Although there is still only a single time stream, phases have the benefit of two time dimensions, physicists report July 20 in the journal. Natural . This mind-bending property offers a much-desired benefit: Information stored in phases is much more protected from error than the alternative settings currently used in quantum computers. As a result, information can last longer without becoming garbled, an important milestone to create quantum computing Perform computations using quantum mechanical phenomena such as superposition a

Hawaii’s volcanic environment contains a mysterious variety of microbes, new research has discovered this week. Scientists say that the island’s lava caves and other structures created by volcanic activity have unique, diverse, and still-living bacterial communities within them. The findings suggest that much remains to be learned about life in some of the most extreme conditions on Earth. Researchers at several universities and NASA collaborated for the study, which was published Thursday in Frontiers in Microbiology. They studied samples collected from 70 sites along the Big Island of Hawaii, the largest island in the Hawaiian archipelago. These sites include caves, tubes, and fumaroles, which are openings or vents through which volcanic gases and water can escape. They analyzed and sequenced the RNA found in the samples, making it possible to create a rough map of the bacterial community living there. Stalactite formations in the Hawaiian cave system from this study with co

Summary: In a study of speakers of 45 languages, researchers found similar patterns of brain activity and language selectivity. Source: MIT For decades, neuroscientists have created well-defined maps of the brain’s “language network,” or regions of the brain specialized for processing language. Found primarily in the left hemisphere, this tissue includes areas within Broca’s area, as well as in other parts of the frontal and temporal lobes. However, most of these mapping studies were conducted on English speakers while they were listening to or reading English texts. MIT neuroscientists have now conducted brain imaging studies of speakers of 45 different languages. The results show that the language network of speakers appears to be essentially the same as that of native English speakers. This finding, though not surprising, establishes that the location and key properties of language networks appear to be universal. This work also lays the groundwork for the future study of lingui

Scientists working at the CERN laboratory recently announced the discovery of exotic matter not seen in nature: two distinct “tetraquarks” and “pentaquarks,” all of which were created in the collision between pairs of protons colliding with each other at very close velocities. lamp speed. The energy from this collision is literally transmuted into these exotic particles, a process governed by Einstein’s famous equation E = mc 2 . They will provide a new method for studying the forces that bind atomic centers together. What are quarks? Quarks were proposed in 1964 by American physicist Murray Gell-Mann as a solution to a major problem at the time. From the late 1940s to the early 1960s, physicists discovered hundreds of particles with a dizzying array of masses, electric charges, lifetimes, and ways in which the particles interacted. So many different particles had been discovered with such diverse properties that researchers at the time referred to the zoo as a “particle zoo”. At

A team of physicists at MIT recently published a stunning research paper detailing their successful attempt to use entanglement and ‘quantum time reversal’ to create sensors capable of taking very deep measurements. It sounds like a lot of science jargon, but the point is this could potentially lead to a legitimate ‘dark matter detector’, and it’s something that could revolutionize humanity’s understanding of everything . In advance: Physics is a moving target. Because we are like fish in an aquarium, we don’t know where the water we are swimming is coming from or what lies behind the blurry shadows on the edge of our glass-paneled horizon.
