Phys.org / TIME instrument unlocks faint signals from early galaxies across vast stretches of sky
Cornell astronomers are deploying a new instrument that grants them, for the first time, a better view of the universe's earliest galaxies, which can't be observed individually with traditional ground- or space-based telescopes.
Phys.org / A baby bird's wish list: Mild weather, attentive parents, not being the smallest sibling
Experiences in the first days and weeks of life can have a profound impact on humans—and birds. A new study led by Sage Madden, a graduate student in evolution and ecology at the University of California, Davis, shows how ...
Phys.org / Quantum circuit test finally exposes what has been warping performance
Quantum computers could someday solve pressing problems that are too convoluted for classical computers, such as modeling complex molecular interactions to streamline drug discovery and materials development.
Phys.org / How a single radioactive cloud caused Fukushima particle contamination
A new study shows that a single radioactive cloud was responsible for a large share of the nuclear fallout during the Fukushima Daiichi nuclear disaster on 11 March 2011. The work is published in the Journal of Hazardous ...
Phys.org / Old newspapers track porpoise populations across the Baltic Sea
Harbor porpoises were once found across a much wider area of the Baltic Sea than they are today, including regions where they are now rare or absent. This is shown in a new study that uses centuries-old Swedish newspapers ...
Phys.org / 'Implosion carving' shrinks 3D photonic devices 2,000-fold for visible-light computing
Using a new technique that can create vacancies at any site across a material and then shrink it to about 1/2,000 of its original volume, MIT researchers have designed nanotechnology devices that could be used for optical ...
Phys.org / The shoal remembers: How signs of a collective memory shape a predator-prey arms race
Beneath the tropical trees of southern Mexico, enormous shoals of sulfur mollies blanket the water surface of toxic sulfur springs, where survival depends on collective defense against relentless attacks from predatory birds. ...
Dialog / Novel technique measures polymer degradation during cathodic overprotection
Oil and natural gas are vital constituents of our energy ecosystem that need to be transported across long distances. Although steel pipelines are the infrastructure used for this purpose, thereby serving as the lifeline ...
Phys.org / The fog is alive: Droplets host bacteria that clear toxins from our air
What if fog isn't just misty air, but a living ecosystem? This question hung over cloud researcher Thi Thuong Thuong Cao. As a Ph.D. student at Arizona State University, her curiosity led her from knocking on the doors of ...
Phys.org / Ancient bacterial toolkit links human gut health to ocean carbon cycling
Our gut is colonized by legions of bacteria, which supply us with essential nutrients and support our health. Among them are Akkermansia bacteria, which might be helpful in the management of conditions like obesity and diabetes.
Phys.org / Scientists dispute hypothesis that climate change will unleash massive agricultural pest populations
The widespread hypothesis that climate warming will result in unprecedented agricultural pest populations and cause food insecurity worldwide is oversimplified, according to a new study by a team led by Mia Lippey, an entomologist ...
Phys.org / AI surrogate accelerates nonlinear optics simulations by orders of magnitude
Simulating the nonlinear optical physics that underlies ultrafast laser systems is computationally demanding—a practical bottleneck in settings that require rapid feedback. A study by researchers at Stanford University, University ...
