Phys.org / Ancient bone arrow points reveal organized craft production in prehistoric Argentina
For decades, research and understanding of the diverse bone raw material used by the Late Prehispanic Period (~1220 to 330 cal BP) people of the Sierras de Córdoba were scarce. However, Dr. Matías Medina and his colleagues, ...
Phys.org / Veritas explores the nature of a mysterious gamma-ray emitter
Astronomers have employed the Very Energetic Radiation Imaging Telescope Array System (VERITAS) to observe a mysterious gamma-ray emitting source designated HESS J1857+026. Results of the observational campaign, published ...
Phys.org / Why we may be misreading our dogs' emotions
Humans and dogs have been living together side by side for thousands of years, so you would think we know everything about our four-legged friends by now. But we may not understand them as well as we think we do.
Phys.org / Evidence of a quantum spin liquid ground state in a kagome material
Quantum spin liquids are exotic states of matter in which spins (i.e., the intrinsic angular momentum of electrons) do not settle into an ordered pattern and continue to fluctuate, even at extremely low temperatures. This ...
Phys.org / Mathematicians crack cellular noise puzzle, paving path for better cancer treatment
Why does cancer sometimes recur even after successful treatment, or why do some bacteria survive despite the use of powerful antibiotics? One of the key culprits identified is "biological noise"—random fluctuations occurring ...
