Researchers have created a new optical illusion that makes your brain try to predict the future — namely, entering a dark tunnel.
Double Jeopardy with False Positives? And how this Relates to the Search for Extraterrestrial Life.

Putin also said that Russia would suspend its participation in a treaty aimed at keeping a lid on nuclear weapons expansion. The so-called New START Treaty was signed by Russia and the U.S. in 2010. It caps the number of long-range nuclear warheads they can deploy and limits the use of missiles that can carry atomic weapons.
Putin said Tuesday in a major address that Russia was not fully withdrawing from the treaty yet. He said Russia must stand ready to resume nuclear weapons tests if the US does so.
Russian President Vladimir Putin accused Western countries Tuesday of igniting and sustaining the war in Ukraine, refusing any blame for Moscow almost a year after the Kremlin’s invasion of its neighbor that has killed tens of thousands of people.
Out of numerous companies that have created quantum technology, these 6 are particularly known for their work in superconducting qubits.
Such credentials in the wrong hands could be dangerous, experts say, potentially allowing physical access to data centers. The affected data center operators say the stolen information didn’t pose risks for customer IT systems.
A prime target in the search for extraterrestrial life is Europa, a moon of Jupiter that’s covered with a sheet of salty ice. But what kind of salt is there? Researchers say they’ve created a new kind of salt crystal that could fill the bill, and perhaps raise hopes for finding life under the ice.
This salt crystal is both exotic and common: It’s actually table salt — also known as sodium chloride, with the chemical formula NaCl — but bound up with water molecules to form a hydrate that doesn’t exist naturally on Earth.
Researchers at Purdue University have discovered new waves with picometer-scale spatial variations of electromagnetic fields which can propagate in semiconductors like silicon. The research team, led by Dr. Zubin Jacob, Elmore Associate Professor of Electrical and Computer Engineering and Department of Physics and Astronomy (courtesy) published their findings in APS Physics Review Applied in a paper titled, “Picophotonics: Anomalous Atomistic Waves in Silicon.”
“The word microscopic has its origins in the length scale of a micron which is a million times smaller than a meter. Our work is for light matter interaction within the picoscopic regime which is far smaller, where the discrete arrangement of atomic lattices changes light’s properties in surprising ways.” says Jacob.
These intriguing findings demonstrate that natural media host a variety of rich light-matter interaction phenomena at the atomistic level. The use of picophotonic waves in semiconducting materials may lead researchers to design new, functional optical devices, allowing for applications in quantum technologies.
Rs-fMRI is used to investigate human brain connectivity changes induced by prolonged microgravity in cosmonauts before and after spaceflight, with both persistent and reversible location specific changes in connectivity being observed.
The outer layer of the brain, known as the cortex, is made of different types of neurons. Neuroscience studies suggest that these different neuron types have distinct functions, yet for a long time this was difficult to ascertain, due to the inability to examine and manipulate them in the brains of living beings.
In recent years, genetic techniques opened new possibilities for studying cells and their functions. Using some of these techniques, researchers at Forschungszentrum Jülich, RWTH Aachen University, Cold Spring Harbor Laboratory and other institutes in the United States closely examined the functions of different pyramidal cells, which are commonly found in the human cortex.
Their findings, published in Nature Neuroscience, suggest that distinct types of pyramidal cells drive patterns of cortical activity associated with different brain functions. The team’s study builds on some of their previous works focusing on neuronal activity in the cortex.
A combined team of physicists from Harvard University and Northwestern University has found the most precise value yet for the magnetic moment of an electron. In their paper published in the journal Physical Review Letters, the group describes the methods they used to measure properties of an electron and implications of the new precision.
The magnetic moment of an electron, also known as the electron magnetic dipole moment, results from its electric and spin properties. Of all the elementary properties that have been studied, it is the one that has been the most precisely measured, and also the most accurately verified.
Measuring the magnetic moment of an electron to ever higher standards of accuracy is important because physicists believe that at some point, such measurements will help to complete the standard model of physics. In this new effort, the research group has measured the magnetic moment to a precision twice that of any other effort—the last best effort was 14 years ago.
