First some mathematics items: Igor Shafarevich, one of the great figures of twentieth century algebraic geometry and algebraic number theory, died this past weekend at the age of 93. Besides his many contributions to mathematics research, he was also a … Continue reading ?

Science versus the 'Horatio Alger myth'

In a new study published today in the journal PLOS ONE, Los Alamos National Laboratory scientists have taken a condensed matter physics concept usually applied to the way substances such as ice freeze, called "frustration," and applied it to a simple social network model of frustrated components.

Researchers gain insight into a physical phenomenon that leads to earthquakes

Scientists have gotten better at predicting where earthquakes will occur, but they're still in the dark about when they will strike and how devastating they will be.

Artificial intelligence in quantum systems, too

Quantum biomimetics consists of reproducing in quantum systems certain properties exclusive to living organisms. Researchers at University of the Basque Country have imitated natural selection, learning and memory in a new study. The mechanisms developed could give quantum computation a boost and facilitate the learning process in machines.

Physicists investigate erasing information at zero energy cost

(Phys.org)—A few years ago, physicists showed that it's possible to erase information without using any energy, in contrast to the assumption at the time that erasing information must require energy. Instead, the scientists showed that...Show More Summary

Laser heating hits the spot

A method for accurately measuring the thermomagnetic properties of heat-assisted magnetic recording (HAMR) media reveals what the minimum bit size and ultimate data density might be for this next generation storage technology.

Time crystals—how scientists created a new state of matter

Some of the most profound predictions in theoretical physics, such as Einstein's gravitational waves or Higgs' boson, have taken decades to prove with experiments. But every now and then, a prediction can become established fact in an astonishingly short time. Show More Summary

Scientists create a nano-trampoline to probe quantum behavior

A research group from Bar-Ilan University, in collaboration with French colleagues at CNRS Grenoble, has developed a unique experiment to detect quantum events in ultra-thin films. This novel research, to be published in the scientific journal Nature Communications, enhances the understanding of basic phenomena that occur in nano-sized systems close to absolute zero temperature.

Putting to good use: Old lab equipment goes to new science

Some older lab instruments may have outlived their usefulness in Fermilab experiments, but that doesn't mean they can't live on in other science projects.

Parents' enthusiasm for science boosts teens' exam scores

Talking to children about importance of STEM influences career choices

TeV Particle Astrophysics 2017 -- TeVPA 2017

Conference: 7 Aug 2017 - 11 Aug 2017, Columbus, Ohio, United States. Organized by Center for Cosmology and AstroParticle Physics (CCAPP), The Ohio State University.

Synopsis: Neutrino Flashes from Exploding Stars

Calculations indicate that neutrino emission from a supernova could be detected on Earth, possibly revealing how the star explodes. [Physics] Published Tue Feb 21, 2017

New design for longer lasting night-vision cameras

With the amazing ability to survey areas in complete darkness, night-vision cameras have revolutionized the security industry. But the materials and technology embodied in current cameras tend to degrade under temperature stress, causing night-vision devices to frequently break.

Viewpoint: A Crumpled Sheet’s Remembrance of Things Past

Author(s): Nathan Keim Crumpled sheets “remember” the application and removal of a force for days, a newly discovered memory effect that suggests crumpled sheets are a lot like glasses. [Physics 10, 18] Published Tue Feb 21, 2017

Engineers overcome a hurdle in growing a revolutionary optical metamaterial

When John Crocker, a professor of chemical and biomolecular engineering in the University of Pennsylvania's School of Engineering and Applied Science was a graduate student, his advisor gathered together everyone in his lab to "throw down the gauntlet" on a new challenge in the field.

Scientists combine the ultra-fast with the ultra-small to pioneer microscopy at terahertz frequencies

For the first time ever, scientists have captured images of terahertz electron dynamics of a semiconductor surface on the atomic scale. The successful experiment indicates a bright future for the new and quickly growing sub-field called terahertz scanning tunneling microscopy (THz-STM), pioneered by the University of Alberta in Canada.

New approach to measure fluid drag on the body during swimming

A key factor to improve swimming performance is reducing resistance that water exerts on the moving body. This resistance, known as drag, is influenced by factors including the stroke rate, swimmer's size, and swimming speed. The range of factors, along with the motion of the swimmer, have made it difficult to measure drag accurately.
