Phys.org / Hunted by Neanderthals, giant elephants traveled hundreds of kilometers across ice-age Europe
Neumark-Nord in northeastern Germany was a lake landscape in the last interglacial period. It is rich in archaeological finds discovered during lignite mining. The area in Saxony-Anhalt is one of the most important European ...
Phys.org / Amazonian chocolate: Combining cocoa clones with different post-harvest processes balances flavor and nutritional value
Chocolate produced in the Amazon is internationally recognized for its unique flavor. A study by researchers at São Paulo State University (UNESP) in Brazil has shown that it could be even more valuable. The analysis indicates ...
Phys.org / A clear roadmap for engineering combs of light
Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for precision measurement, found in optical clocks, gas-sensing spectrometers, and instruments that detect ...
Phys.org / Cannibalism takes major bite out of young blue crabs, but the shallows offer a refuge
The Chesapeake Bay's most popular crustacean has a dark streak. Cannibalism is the No. 1 killer of juvenile blue crabs in mid-salinity waters where they are known to congregate, according to a new study from the Smithsonian ...
Phys.org / Ocean bacteria team up to break down biodegradable plastic
Biodegradable plastics could help alleviate the plastic waste crisis that is polluting the environment and harming our health. But how long plastics take to degrade and how environmental bacteria work together to break them ...
Phys.org / Laser-assisted electron scattering seen with circularly polarized light for the first time
Researchers from Tokyo Metropolitan University have succeeded in detecting laser-assisted electron scattering (LAES) using circularly polarized light for the first time. The use of circularly polarized light promises valuable ...
Phys.org / Molecular chains with bite: Customized carbon nanoribbons open a cleaner path to molecular electronics
The longest chains of the conductive polymer poly(p-phenylene; PPP) produced to date are just under one micrometer (thousandth of a millimeter) long—almost an order of magnitude longer than previously possible. A research ...
Phys.org / Why sugar breakdown matters beyond energy—new insights into how it makes cells move
It has long been known that our bodies derive energy from sugar. Researchers at RPTU University Kaiserslautern-Landau have now discovered that sugar breakdown produces an intermediate product that is also crucial for the ...
Phys.org / Milk-derived nanoparticles may enable physicians to target aggressive bile duct cancer
Mayo Clinic researchers have developed a promising new way to deliver treatment directly to cholangiocarcinoma tumors, a rare and aggressive bile duct cancer with limited treatment options, using milk-derived nanoparticles ...
Phys.org / Photonics and nanotech could spot cancer signals 5 to 8 years earlier
Timing is critical in diagnosing diseases such as cancer. Researchers within The Grainger College of Engineering at the University of Illinois Urbana-Champaign used a historically underappreciated tiny powerhouse to detect ...
Phys.org / A new class of molten planet stores abundant sulfur in a perpetual magma ocean
A study led by the University of Oxford has identified a new type of planet beyond our solar system—one that stores large amounts of sulfur deep within a permanent ocean of magma. The findings have been published in Nature ...
Phys.org / Q&A: Reevaluating reaction rates to better understand the stars
Thermonuclear reaction rates power the models that explain how stars live, explode and create the elements. A new study co-authored by NC State faculty member Richard Longland provides a comprehensive, statistically grounded ...
