A new way to measure gravity: Using floating atoms

Posted by in category: particle physics

A team of researchers at the University of California, Berkeley, has found a new way to measure gravity—by noting differences in atoms in a supposition state, suspended in the air by lasers. In their paper published in the journal Science, the group describes their new technique and explain why they believe it will be more useful than traditional methods.

Currently, the standard way to conduct gravity experiments is to drop things down shielded tubes and measure them as they whiz by instruments. In addition to giving researchers a very brief glimpse of gravitational interactions, such methods often fall prey to inadvertent stray magnetic fields. In this new effort, the researchers have found a way to measure gravity that does not involve dropping objects at all.

The new approach involved releasing a cloud of cesium atoms into the air in a small chamber and then using to split several of them into a superposition state. Once split, lasers were used to keep all the atoms in fixed positions with one of each pair raised slightly higher than its mate. The team then measured each atom’s wave particle duality, which is impacted by gravity. By measuring the difference in duality between the paired atoms (because of the difference in their distances from Earth), the researchers were able to come up with a measurement for gravity.

Researchers convert 2-D images into 3D using deep learning

Posted by in category: robotics/AI

A UCLA research team has devised a technique that extends the capabilities of fluorescence microscopy, which allows scientists to precisely label parts of living cells and tissue with dyes that glow under special lighting. The researchers use artificial intelligence to turn two-dimensional images into stacks of virtual three-dimensional slices showing activity inside organisms.

In a study published in Nature Methods, the scientists also reported that their framework, called “Deep-Z,” was able to fix errors or aberrations in images, such as when a sample is tilted or curved. Further, they demonstrated that the system could take 2-D images from one type of and virtually create 3D images of the sample as if they were obtained by another, more advanced microscope.

Attoseconds break into atomic interior

Posted by in categories: particle physics, quantum physics

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very bright, and the photons delivered must have sufficiently high energy. This combination of properties has been sought in laboratories around the world for the past 15 years. Physicists at the Laboratory for Attosecond Physics (LAP), a joint venture between the Ludwig-Maximilians-Universität Munich (LMU) and the Max Planck Institute of Quantum Optics (MPQ), have now succeeded in meeting the conditions necessary to achieve this goal. In their latest experiments, they have been able to observe the non-linear interaction of an attosecond pulse with electrons in one of the inner orbital shells around the atomic nucleus. In this context, the term ‘non-linear’ indicates that the interaction involves more than one photon (in this particular case two are involved).

Freeman Dyson (Scientist)

Posted by in categories: biotech/medical, neuroscience

Abstract: We know that creatures like us have two separate systems for processing information, the genome and the brain. We know that the genome is digital, and we can accurately transcribe our genomes onto digital machines. We cannot transcribe our brains, and the processing of information in our brains is still a great mystery. I will be talking about real brains and real people, asking a question that will have practical consequences when we are able to answer it. I am not able to answer it now. All I can do is to examine the evidence and explain why I consider it probable that the answer will be that brains are analog.

The Physics of God: Unifying Quantum Physics, Consciousness, M-Theory, Heaven, Neuroscience and

Posted by in categories: alien life, life extension, neuroscience, quantum physics

What if god was literally real. Let’s just posit that instance. What if a type 7 civilization existed. What if the realm of impossibility of dream existed. I think if a realm of impossibility existed it have literal physics. This book talks about this real instance of possible impossibility. What if water into wine literally happened it would have a literal physics. In the realm of science of the impossible there could have a literal scientific proof that a chimp with god like powers did exist that essentially maybe it prove of a being that has impossible abilities. Some even posit that god is an alien perhaps. That the universe is a sandbox for us to live much like a video game is. That the vast expansion of this bubble universe with its realm of physics that has near endless possibilities stands to reason of a creator that has made those to be. That it is not just farming we do on earth but rather something different that even in a grain of sand there is infinite possibilities because essentially it was manufactured by a god like being that physically existed. This could rewrite the history books even proving that god does exist as an actual being of immense abundance and power. M theory would solve the questions we all hold dear that the secrets of the universe may be hidden in m theory.


Setting aside the pervasive material bias of science and lifting the obscuring fog of religious sectarianism reveals a surprisingly clear unity of science and religion. The explanations of transcendent phenomena given by saints, sages, and near-death experiencers—miracles, immortality, heaven, God, and transcendent awareness—are fully congruent with scientific discoveries in the fields of relativity, quantum physics, medicine, M-theory, neuroscience, and quantum biology.

Modified CRISPR gene editing tool could improve therapies for HIV, sickle cell disease

Posted by in categories: bioengineering, biotech/medical, genetics

City of Hope researchers may have found a way to sharpen the fastest, cheapest and most accurate gene editing technique, CRISPR-Cas9, so that it can more successfully cut out undesirable genetic information.

This improved cutting ability could one day fast-track potential therapies for HIV, and, potentially, other immune conditions.

“Our CRISPR-Cas9 design may be the difference between trying to cut a ribeye steak with a butter knife versus slicing it with a steak knife,” said Tristan Scott, Ph.D., lead author of the study and a staff research scientist at City of Hope’s Center for Gene Therapy. “Other scientists have tried to improve CRISPR cutting through chemical modifications, but that’s an expensive process and is like diamond-coating a blade. Instead, we have designed a better pair of scissors you can buy at any convenience store.”
