Phys.org / Human sacrifice in Inca Empire may have been driven by political motives, not religion
Three decades ago, researchers working atop the Llullaillaco volcano, located on the border between Argentina and Chile, discovered exceptionally well-preserved remains. The find included the mummified bodies of three children ...
Phys.org / Well-known planetary nebula's ear-like lobes rewrite its evolutionary timeline
Using the Multi Unit Spectroscopic Explorer (MUSE) and the Manchester Echelle Spectrograph (MES), astronomers from Turkey and Mexico have investigated a planetary nebula discovered two centuries ago, known as NGC 6563. Results ...
Phys.org / El Niño is underway, satellite observations show
El Niño, characterized by warmer-than-normal water temperatures in parts of the equatorial Pacific, made its return in June 2026. Observations of sea surface height from the Sentinel-6 Michael Freilich satellite that month ...
Phys.org / Quantum mechanics theory may work without imaginary numbers, new analysis suggests
Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In an article published in the journal Physical ...
Phys.org / Nanoscale CoAl design delivers 6 GPa strength with 15% plastic strain at room temperature
Materials engineers have developed the ability to manipulate structure and matter at the nanoscale for solid-state alloys called intermetallics, making it possible to alter their properties for improved performance.
Phys.org / Arctic marine heat waves surge since 1980s, with record event lasting 480 days
In recent years, marine heat waves have been taking an ever-greater toll on the world's oceans and their ecosystems. Amplified by increasing global warming, these events are occurring more frequently and lasting longer. The ...
Phys.org / Stress gives bees sharper vision and faster reactions, researchers discover
Bumblebees see the world differently under stress, processing visual information more sharply and making quicker decisions, new research from Newcastle University reveals.
Phys.org / Engineered bacterial spores reveal new protein targets for enzymes and vaccines
A remarkable quality of bioengineering is that scientists can take biological processes honed by millions of years of evolution and use them to efficiently create drugs, chemicals and other products to improve our lives. ...
Phys.org / Modular nanorobot self-assembles, targets cancer cells and cuts viability
A team at the University of Basel, Switzerland, has developed a versatile nanorobot with propulsion and payload modules. The two reusable modules autonomously self-assemble and could be used in medicine or industry.
Phys.org / Tropical ocean temperatures may drive changes in malaria cases in Malawi
Malaria is one of the world's deadliest infectious diseases. Because it is transmitted by mosquitoes, malaria is extremely sensitive to environmental conditions like rainfall and temperature that affect mosquito survival ...
Phys.org / Jumping gene caught moving between species in first direct observation
Genes are not passed on exclusively from parents to their offspring. Some are mobile and can also jump to other species, as researchers at the Max Planck Institute for Marine Microbiology in Bremen have now shown. The direct ...
Phys.org / Ancient Mongolian cemetery reveals power and status mattered more than blood ties
On the edge of the Mongolian steppe, overlooking where two rivers meet, lies an ancient cemetery. Buried within are two families, traced through ancient DNA across six generations, surrounded by dozens of "strangers." The ...
