Phys.org / Cosmologists collaborate to sharpen measurements of the Hubble constant
Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in Astronomy & Astrophysics, ...
Phys.org / Atomic distortions reveal new clues about superconductivity
A team of researchers has identified atomic distortions that may be linked with high-temperature superconductivity in a promising class of nickel-based materials, offering new insight into how next-generation superconductors ...
Phys.org / 'Serendipitous' discovery of Martian ripple marks reveals an ancient sandstorm
The search for life on Mars involves the efforts of scientists from many different disciplines. An important aspect of that search is to study Martian sedimentary rocks for information about the planet's environment when ...
Phys.org / Compact flat-lens system can generate nondiffracting bottle beams
Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long distances. To overcome this challenge, ...
Phys.org / Deep mantle deformation is linked to subducted slabs, global map shows
Slow roiling convection currents deep within Earth's mantle, which are associated with the movements of tectonic plates, also deform the material of the mantle itself. Now, a new study in The Seismic Record confirms that ...
Phys.org / Engineered E. coli dependency may help contain microbes to defined areas
Take a typical fish out of the water and it won't live long. It gets the oxygen it needs from the water it swims in. In a similar way, scientists are exploring dependency as a method of controlling what microbes can do and ...
Phys.org / UV light method offers repeat recycling for acrylic plastics without the environmental cost
A breakthrough method for chemically recycling acrylic—one of the world's most widely used plastics—has been developed by researchers at the University of Bath. In contrast to conventional mechanical recycling, this method ...
Phys.org / Gravity from positivity: Single massive spin-3/2 particle makes gravity logically inevitable, study claims
Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists in nature. Two principles ...
Phys.org / Spectacular fossil treasure trove pushes back origins of complex animals
A newly discovered fossil site in southwest China has transformed our understanding of how complex animal life emerged on Earth, revealing that many key animal groups had already evolved before the start of the Cambrian Period. ...
Phys.org / New disk-shaped catalyst turns carbon dioxide into methanol at lower temperatures
Low-temperature CO2 hydrogenation might have sounded almost paradoxical until a recent study made it possible. Researchers have designed new catalysts that can transform the greenhouse gas into methanol at temperatures ranging ...
Phys.org / Rudeness may be rewarded—as a response to rudeness
If you don't have anything nice to say, perhaps it's OK to say it anyway—if responding to someone who has treated you or your team rudely, new Cornell research suggests. Civil responses to disrespectful behavior remain the ...
Dialog / New 2D material demonstrates capability for ultrathin waveplates
Polarization has always been a core property of light that is essential for a broad range of everyday applications, including displays (LED, LCD, 3D Cinematics), photography, as well as satellite and antenna technologies. ...
