Phys.org / A 112°C test may separate 1,000-year-old pottery from recent forgeries
Museums around the world now have a new tool to distinguish real ancient clay artifacts from fakes. The research team at UC San Diego's Scripps Institution of Oceanography, led by postdoctoral scholar Yoav Vaknin, found a ...
Phys.org / Peptides can form well-defined structures in harsh, Venus-like conditions
When exploring solar system bodies for signs of past or present life, scientists have mainly focused on planets that have (or had) a liquid surface similar to Earth's. However, mounting evidence suggests that the ingredients ...
Phys.org / Keeping cool saves thousands of lives yearly, but at a cost of worsening global warming, experts say
Cooling from air conditioning saves lives—more than 5,000 a year in the United States alone—but it also heats up the planet and taxes our electrical grid, scientists say.
Phys.org / Manganese's emission lines shine a light on galactic evolution
In a new study, a team of astronomers has identified wavelengths of light that could be useful for tracing the chemical evolution of the universe. Using computational modeling to simulate how electrons interact with manganese ...
Phys.org / New gene activation tool may do what CRISPR cannot: Work inside the body
The ability to precisely adjust the expression of genes inside the human body—ramping up protective ones and tamping down harmful ones—holds enormous potential for treating and preventing disease. But the standard molecular ...
Phys.org / Organic crystal reveals how Joule heating stabilizes resistive switching
Metal-insulator transitions (MITs), in which a material changes from a metallic state with low resistivity to an insulating state because of a change in an external parameter, such as temperature, pressure or an electric ...
Phys.org / Loss of kelp forests reverberates down to the microbial level
As one moves north, Maine's kelp forests are being overtaken by dense mats of carpet-like turf algae. The steady decline of kelp and transition into this new state are altering the ecosystem all the way down to the microbial ...
Phys.org / Why some AI ads fail while others succeed
Artificial intelligence can create realistic depictions of just about anything, but that does not mean advertisers should lean on the technology, according to a study led by University of Mississippi professors.
Phys.org / Solar orbiter detects ion sorting at the solar wind's magnetic boundary
A Southwest Research Institute (SwRI) study of data from the European Space Agency's (ESA) Solar Orbiter gives the most detailed view of the heliospheric current sheet (HCS) to date. The HCS is a sprawling, undulating surface ...
Phys.org / Tiny mirror that controls light in 3D could make microscopes smaller and faster
Researchers use tightly focused laser beams to image biological samples, shape materials with microscopic precision and generate displays. But using those beams in three dimensions requires more than sweeping light from side ...
Phys.org / No smartphone, no problem: Plants have their own built-in 'Season-Meter'
You may check your phone before deciding what to wear tomorrow. Plants do something similar: they carry an internal gadget called a "Season-Meter" that tracks temperatures over the preceding weeks or months to help determine ...
Phys.org / Caught right-handed: Mystery of coiling snake embryos explained
An international team led by Canadian researchers has found evidence explaining why snake embryos form a curious spiral. This ability to coil as embryos enables snakes to hatch with the longest bodies of all vertebrates.
