Researchers discover the evolutionary origins of the cat attractant nepetalactone. Catmint, also known as catnip, is well-known for its intoxicating effect on cats. The odor…
The Oldest Upper Paleolithic Homo Sapiens in Europe Two studies report new Homo sapiens fossils from the site of Bacho Kiro Cave in Bulgaria. “The Bacho Kiro…
An analysis of 369 solar-like stars shows that solar brightness variations are extremely weak. The extent to which solar activity (and thus the number of…
New method of discerning sources of ancient feces makes this archaeological find far more informative. The archaeological record is littered with feces, a potential goldmine…
Humans have been studying the light from stars since the beginning of our history; however, we’ve only just discovered in the last few decades that…
Magnetars are neutron stars endowed with the strongest magnetic fields observed in the Universe, but their origin remains controversial. In a study published in Science…
International team uses a novel approach combining gravitational-wave observations, multi-messenger astronomy, and nuclear physics to obtain the best measurement of neutron star size to date….
Permanent magnets akin to those used on refrigerators could speed the development of fusion energy – the same energy produced by the sun and stars….
By combining modern data analysis techniques with stellar structure modeling for main-sequence and giant stars, researchers shed new light on stellar dynamos. In their interiors,…
New archaeological work supports the hypothesis that human populations were present in India by 80,000 years ago and that they survived one of the largest…
Brain imprints on cranial bones from great apes and humans refute the long-held notion that the human pattern of brain asymmetry is unique. The left…
Processes taking place inside tiny electronic components or in molecules can now be filmed at a resolution of a few hundred attoseconds and down to…
Atomic frequencies measured with 100 million times higher resolution. Scientists from the PTB and the Max Planck Institute for Nuclear Physics (MPIK), both Germany, have…
Basic cooperation skills appear to be shared by dogs and wolves, suggesting that this ability was present in a common ancestor and was not lost…
The physical process driving Gamma-Ray Bursts might be synchrotron radiation after all. A new analysis of Fermi/GBM archival data of gamma-ray bursts (GRB), the most…
The first comprehensive study of the human ability to recognize the facial expressions of dogs suggests this ability is mainly acquired through age and experience…
New archeological analysis challenges long-standing hypotheses about ostrich eggshell beads and the spread of pastoralism in Africa. Ostrich eggshell beads are some of the oldest…
A new miniature NMR implant measures neuronal activity. A team of neuroscientists and electrical engineers from Germany and Switzerland developed a highly sensitive implant that…
