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…
