Infrared vision for immunotherapy
A new technique employs a bright infrared light that can pass through millimeters of tissue to illuminate tumors deep inside the body. Stanford chemists have developed a new deep-tissue imaging technique that can see beneath the skin of living subjects to illuminate buried tumors with unparalleled clarity.

How AI could change science
When most people encounter artificial intelligence today, it's recommending a new song or movie. But that's only the start to what's possible. AI technology is increasingly used to open up new horizons for scientists and researchers. At the University of Chicago, researchers are using it for everything from scanning the skies for supernovae to finding new drugs from millions of potential combinations and developing a deeper understanding of the complex phenomena underlying the Earth's climate.

Quantum material goes where none have gone before ?
Quantum material goes where none have gone before ?
Alloy behaves strangely while traversing potential 'spin liquid' state Rice University physicist Qimiao Si began mapping quantum criticality more than a decade ago, and he's finally found a traveler that can traverse the final frontier. The traveler is an alloy of cerium palladium and aluminum, and its journey is described in a study published online this week by Si, a theoretical physicist and director of the Rice Center for Quantum Materials (RCQM), and colleagues in China, Germany and Japan.

Growing old together: a sharper look at black holes and their host galaxies
Some relationships are written in the stars. That's definitely the case for supermassive black holes and their host galaxies, according to a new study from Yale University. The "special relationship" between supermassive black holes (SMBHs) and their hosts - something astronomers and physicists have observed for quite a while - can now be understood as a bond that begins early in a galaxy's formation and has a say in how both the galaxy and the SMBH at its center grow over time, the researchers note.

Quantum Mechanics survives a gravity test
Quantum Mechanics survives a gravity test
Scientists have challenged one of the great mysteries of physics - by undertaking an experiment in space proposed by The University of Queensland a decade ago. The School of Mathematics and Physics' Professor Timothy Ralph collaborated on the study, which he said could help bring quantum technologies, such as a global quantum internet, closer to being part of everyday life.

How to dismantle a nuclear bomb
How to dismantle a nuclear bomb
MIT team successfully tests a new method for verification of weapons reduction. UPI reporter Brooks Hays writes that MIT researchers has developed a new test to verify the destruction of nuclear weapons. "The test can identify the specific isotope of the target element, which could allow inspectors to confirm the identity of a warhead before it's disassembled," writes Hays.

Particle physicists lend a hand to advance neuroscience
Particle physicists lend a hand to advance neuroscience
After meeting at a party, a Stanford psychologist and SLAC particle physicists have collaborated on a new kind of EEG device that can stimulate the brain and read out the effects. Psychologist Anthony Norcia had a problem. In his research untangling vision processing in the brain, he wanted to simultaneously zap the brain with electricity and measure the electrical aftereffects - two techniques commonly used to probe brain function, but never successfully combined.

More accurate than expected
More accurate than expected
Despite their extremely small mass, neutrinos play a key role in cosmology and particle physics. After evaluation of the first measurement results in the Karlsruhe Tritium Neutrino Experiment (KATRIN), it is now clear: The previously unknown mass of the neutrinos must be less than 1 electron volt. This result is more accurate than previous measurements and raises hopes of discovering new neutrino properties.

An Elegant Solution to the Soft Sensing Challenge
From warehouses to hospitals, soft robots are used in different places to assist humans in moving items, treating patients and gathering information. As interests in these robots keep growing, Carnegie Mellon University scientists are developing ways to give them the kind of sensing capabilities found in natural soft tissue.

A planet that should not exist
A planet that should not exist
Astronomers detected a giant planet orbiting a small star. The planet has much more mass than theoretical models predict. While this surprising discovery was made by a Spanish-German team at an observatory in southern Spain, researchers at the University of Bern studied how the mysterious exoplanet might have formed.

Galaxy found to float in a tranquil sea of halo gas
Galaxy found to float in a tranquil sea of halo gas
Using one cosmic mystery to probe another, an international team of astronomers has analyzed the signal from a fast radio burst - an enigmatic blast of cosmic radio waves lasting less than a millisecond - to characterize the diffuse gas in the halo of a massive galaxy. Their findings , published online  Sept.

Detailed PICture reveals how tooth enamel is strong enough to last a lifetime
Break any bone in the human body, and the body can repair the tissue and fix the damage. Yet tooth enamel - the strongest tissue in the human body - cannot repair itself. Still, our teeth last a lifetime. "We apply huge pressure on tooth enamel every time we chew, hundreds of times a day," says Pupa Gilbert , professor of physics at the University of Wisconsin-Madison.

Ultra rare kaon decay could lead to evidence of new physics
Scientists searching for evidence of new physics in particle processes that could explain dark matter and other mysteries of the universe have moved one step closer, with the new result of the NA62 experiment reported today at CERN. An international team of scientists have succeeded in harnessing a new technique which captures and measures the ultra rare decay of a sub atomic particle called a kaon.

Enigmatic radio burst illuminates a galaxy's tranquil halo
Enigmatic radio burst illuminates a galaxy’s tranquil halo
Astronomers using ESO's Very Large Telescope have for the first time observed that a fast radio burst passed through a galactic halo. Lasting less than a millisecond, this enigmatic blast of cosmic radio waves came through almost undisturbed, suggesting that the halo has surprisingly low density and weak magnetic field.

A radio that searches for dark matter
A radio that searches for dark matter
An "out there" theory inspired the development of the Dark Matter Radio, a device that could explain the mysterious matter that makes up 85 percent of the mass of our universe. A team of Stanford University researchers are on a mission to identify dark matter once and for all. But first, they'll need to build the world's most sensitive radio.

Precision physics with 'tabletop' experiments
Precision physics with ’tabletop’ experiments
With the future of large particle accelerators uncertain, Stanford theorists are exploring the use of smaller, more precise "tabletop" experiments to investigate fundamental questions in physics. The history of particle accelerators is one of seemingly constant one-upmanship. Ever since the 1920s, the machines - which spur charged particles to near light speeds before crashing them together - have grown ever larger, more complex and more powerful.

The quantum superposition principle has been tested on a scale as never before in a new study by scientists at the University of Vienna in collaboration with the University of Basel. Hot, complex molecules composed of nearly two thousand atoms were brought into a quantum superposition and made to interfere.

Plasma flow near sun's surface explains sunspots, other solar phenomena
Plasma flow near sun’s surface explains sunspots, other solar phenomena
For 400 years people have tracked sunspots, the dark patches that appear for weeks at a time on the sun's surface. They have observed but been unable to explain why the number of spots peaks every 11 years. A University of Washington study published this month in the journal Physics of Plasmas proposes a model of plasma motion that would explain the 11-year sunspot cycle and several other previously mysterious properties of the sun.
