A hopper could explore more than 150 km of Triton"s surface in two years
Neptune's largest moon, Triton, is one of the most biologically interesting places in the solar system. Despite being hard to reach, it appears to have active volcanoes, a thin atmosphere, and even some organic molecules called tholins on its surface.....»»
NASA demonstrates "ultra-cool" quantum sensor for first time in space
NASA's Cold Atom Lab, a first-of-its-kind facility aboard the International Space Station, has taken another step toward revolutionizing how quantum science can be used in space. Members of the science team measured subtle vibrations of the space sta.....»»
A new approach to fine-tuning quantum materials
Quantum materials—those with electronic properties that are governed by the principles of quantum mechanics, such as correlation and entanglement—can exhibit exotic behaviors under certain conditions, such as the ability to transmit electricity w.....»»
Cricket physics: Wind tunnel experiments reveal why bowling with a near horizontal arm makes for tough batting
Key to winning a cricket match is tricking the other team's batters—no small feat, as bowlers bowl cricket balls nearly 100 miles per hour. In recent years, a bowling technique that has become popular involves keeping the arm almost entirely horizo.....»»
Study unveils limits on the extent to which quantum errors can be "undone" in large systems
Quantum computers have the potential of outperforming conventional computers on some practically relevant information processing problems, possibly even in machine learning and optimization. Yet their large-scale deployment is not yet feasible, large.....»»
The Physics of Cold Water May Have Jump-Started Complex Life
When seawater gets cold, it gets viscous. This fact could explain how single-celled ocean creatures became multicellular when the planet was frozen during “Snowball Earth,” according to experiments......»»
Almost unfixable “Sinkclose” bug affects hundreds of millions of AMD chips
Worse-case scenario: "You basically have to throw your computer away." Security flaws in your computer's firmware, the deep-seated code that loads first when you turn the machine on and controls even how its operating system boots up.....»»
Does Jewelry and Big Hair Slow Down Olympic Runners?
Even a little added weight and air drag can make a measurable difference. But WIRED's physics guru says, if it makes you feel strong, go for it!.....»»
Achieving quantum memory in the notoriously difficult X-ray range
Light is an excellent carrier of information used not only for classical communication technologies but also increasingly for quantum applications such as quantum networking and computing. However, processing light signals is far more complex, compar.....»»
Quantum computing: Finding solutions by the people for the people
PEARC24 launched its first Workshop on Broadly Accessible Quantum Computing (QC) as the full conference began, July 22, in Providence, RI. Led by NCSA's Bruno Abreu and QuEra's Tomasso Macri, 30+ participants included quantum chemists, system adminis.....»»
Study shows people associate kindness with religious belief
Experiments conducted by UC Merced researchers find that people who perform good deeds are far more likely to be thought of as religious believers than atheists. Moreover, the psychological bias linking kindness and helpfulness with faith appears to.....»»
The link between fuzzy images and quantum fields
