It's like rolling the dice for what you get in your vial. Both the FDA and EMA knew this but kept this out of the public view because if it were known, nobody would take the vaccines.Steve KirschAug 31 One of my readers has been trying to get my attention for 8 months on the EMA data leak that happened nearly 2 years ago.He recently posted this substack article documenting his attempts to get visibility on what the EMA document leak revealed.The gem in the article is this video which was posted 18 months ago that few people have seen....

Bent alkyne (left), diradical (center) and cyclobutadiene molecules under atomic force microscopy. (Leo Gross/IBM) If chemists built cars, they'd fill a factory with car parts, set it on fire, and sift from the ashes pieces that now looked vaguely car-like. When you're dealing with car-parts the size of atoms, this is a perfectly reasonable process. Yet chemists yearn for ways to reduce the waste and make reactions far more precise. Chemical engineering has taken a step forward, with researchers from the University of Santiago de Compostela in Spain, the University of Regensburg in Germany, and IBM Research Europe forcing a...

Reconstruction of the Jehol Biota and the well-preserved specimen of Caudipteryx.A team of scientists from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences and from the Shandong Tianyu Museum of Nature (STM) has isolated exquisitely preserved cartilage cells in a 125-million-year-old dinosaur from Northeast China that contain nuclei with remnants of organic molecules and chromatin. The study was published in Communications Biology on Sept. 24.The dinosaur, called Caudipteryx, was a small peacock-sized omnivore with long tail feathers. It roamed the shores of the shallow lakes of the Jehol Biota in Liaoning province during...

"This is in complete disagreement with accepted models based on the energies of its vibrational modes," said lead researcher Alexander Kolesnikov.Scientists at the Department of Energy's Oak Ridge National Laboratory have observed water molecules behaving unlike gas, liquid or solid states. Researchers discovered the new state while subjecting water molecules to extreme confinement. When water molecules were pushed into nanoscale tubes or channels in the mineral beryl, the water molecules become delocalized around a ring, with each molecule adopting "an unusual double top-like shape." Researchers described the new molecular state in the journal Physical Review Letters. "This means that the...

It's the second most abundant substance in the universe. It dissolves more materials than any other solvent. It stores incredible amounts of energy. Life as we know it would not be possible without it. And although it covers more than 70% of the Earth's surface, many parts of the world are in dire straits for lack of it. What is it? The answer, of course, is water. In some ways, water is one of the substances we know best, in part because it makes up 75% of our bodies. Every day we drink it, bathe in it, clean with it...

What will 3D printers ultimately evolve into? No one has a functioning crystal ball in front of them I assume, but a good guess would be a machine which can practically build anything its user desire, all on the molecular, and eventually atomic levels. Sure we are likely multiple decades away from widespread molecular manufacturing, but a group of chemists led by medical doctor Martin D. Burke at the University of Illinois may have already taken a major step in that direction. Burke, who joined the Department of Chemistry at the university in 2005, heads up Burke Laboratories where he...

Need an obscure medicinal compound found only in a jungle plant? Just print it.Say you're a medical researcher interested in a rare chemical produced in the roots of a little-known Peruvian flower. It's called ratanhine, and it's valuable because it has some fascinating anti-fungal properties that might make for great medicines. Getting your hands on the rare plant is hard, and no chemical supplier is or has ever sold it. But maybe, thanks to the work of University of Illinois chemist Martin Burke, you could print it right in the lab. In a new study published in the journal Science...

Air Force Office of Scientific Research and National Science Foundation-funded professor, Dr. Xiang Zhang has demonstrated at the University of California, Berkeley the world's smallest semiconductor laser, which may have applications to the Air Force in communications, computing and bio-hazard detection. The semiconductor, called a plasmon, can focus light the size of a single protein in a space that is smaller than half its wavelength while maintaining laser-like qualities that allow it to not dissipate over time. "Proposed almost seven years ago, researchers had been unable to demonstrate a working plasmonic laser until our experiment," said Zhang. "It is an...

WASHINGTON (Reuters) - An organic molecule has been spotted for the first time in the atmosphere of a planet outside our solar system, a key step toward possibly finding signs of life on a distant world, scientists said. Astronomers using the Hubble Space Telescope found methane in the atmosphere of a planet called HD 189733b, which is about the size of Jupiter and is 63 light-years from Earth, they said in research published on Wednesday in the journal Nature. Organic molecules contain carbon-hydrogen bonds and can be found in living things. Methane, for instance, is found in natural gas and...

Organic molecules found on alien world for first time 18:21 11 February 2008 NewScientist.com news service Stephen Battersby The giant planet HD 189733b is too hot for its methane and water vapour to signal life (Illustration: Christophe Carreau/ESA)Tools Organic molecules – in the form of methane – have been detected on a planet outside our solar system for the first time. The giant planet lies too close to its parent star for the methane to signal life, but the detection offers hope that astronomers will one day be able to analyse the atmospheres of Earth-like worlds. Astronomers Mark Swain and...

In an article in Science magazine, SUNY Downstate researchers describe erasing memory from the brain by targeting a molecular mechanism that controls memory. Finding may be applied to chronic pain, memory loss, and other conditions.Scientists at SUNY Downstate Medical Center have discovered a molecular mechanism that maintains memories in the brain. In an article in Science magazine, they demonstrate that by inhibiting the molecule they can erase long-term memories, much as you might erase a computer disc.Furthermore, erasing the memory from the brain does not prevent the ability to re-learn the memory, much as a cleaned computer disc may be...

A single molecule, trapped between two electrodes, acts as a switch and has a ‘memory’ of the type used in data storage, Swiss and US researchers have found. Heike Riel of IBM’s research labs in Zurich says this is ‘a step along the way’ to making nanoscale electronic components a reality. Using single organic molecules as electronic components could allow researchers to miniaturise circuits far more than conventional techniques allow. They also avoid the interactions between the millions of molecules found in a standard transistor that can disrupt the conduction of charge. The scientists built their switch using a molecule...

THE scientist who led the team that cracked the human genome is to publish a book explaining why he now believes in the existence of God and is convinced that miracles are real. Francis Collins, the director of the US National Human Genome Research Institute, claims there is a rational basis for a creator and that scientific discoveries bring man “closer to God”. His book, The Language of God, to be published in September, will reopen the age-old debate about the relationship between science and faith. “One of the great tragedies of our time is this impression that has been...

Charles Darwin, the 19th century geologist who wrote the treatise 'The Origin of Species, by means of Natural Selection' defined evolution as "descent with modification". Darwin hypothesized that all forms of life descended from a common ancestor, branching out over time into various unique life forms, due primarily to a process called natural selection. However, the fossil record shows that all of the major animal groups (phyla) appeared fully formed about 540 million years ago, and virtually no transitional life forms have been discovered which suggest that they evolved from earlier forms. This sudden eruption of multiple, complex organisms is...

03/29/04 -- Viruses, often able to outsmart many of the drugs designed to defeat them, may have met their match, according to new research from the University of Wisconsin-Madison. The findings show that the introduction of a harmless molecule that uses the same machinery a virus needs to grow may be a potent way to shut down the virus before it infects other cells or becomes resistant to drugs. The results are published in the March issue of the journal, Antimicrobial Agents and Chemotherapy. "When a virus encounters a susceptible cell, it enters and says, 'I'm now the boss,'" explains...

Red meat molecule 'may cause health problems' Eating red meat introduces a potentially dangerous non-human molecule into the body tissues, new research has showed. A study found that the molecule, a sugar only found in non-human mammals, is absorbed into tissues such as blood vessels and secretory cells. Tests showed that it can generate an immune response which might induce harmful inflammation. The scientists have not ruled out a link with cancer and heart disease - although they acknowledge that at present this is speculation. To date, research has focused on the role of red meat saturated fats and chemical...

The molecule that helps us... erm, forget it August 28 2002 at 05:59PM Paris - A molecule which helps the brain delete unwanted information could be to blame for the memory loss which creeps up with old age, according to a Swiss study that was published on Thursday. "Not everything that we learn is useful, so the brain needs a mechanism to prevent itself being burdened by unhelpful details," said researchers Alcino Silva and Sheena Josselyn in the article in the British journal Nature. Studies on mice by the Swiss Federal Institute of Technology in Zurich found that those in...
