Primordial black holes are one of the strongest candidates for the Universe’s dark matter. In this scenario, their abundance would be large enough for at least one object to cross through the inner Solar System per decade. A flyby like this would introduce a wobble into Mars’ orbit, to a degree that today’s technology could
Bubble use evolved in many small invertebrates to enable underwater breathing, but, until recently, there has been no evidence that vertebrate animals use bubbles in a similar manner. Only one group of vertebrates, semi-aquatic Anolis lizards, may be an exception: these lizards dive underwater when threatened and, while underwater, rebreathe a bubble of air over

Archaeologists have unearthed hundreds of Clovis stone tools at the 13,000-year-old campsite of Belson in southwest Michigan; Clovis people traveled to this site annually, probably in the summer, for at least three but likely up to five consecutive years; the stone artifacts also show evidence that the settlers’ diets included a wide variety of animals
Blood groups are complex. The two best known blood group systems are ABO and Rh. Within each blood group, red cells can carry surface markers called antigens. For example, within the ABO blood group system, there are the A and B antigens — people with A have the A antigen, people with B have the
Using images from the JunoCam instrument aboard NASA’s Juno spacecraft, planetary scientists have spotted a fresh volcano with multiple lava flows and volcanic deposits covering an area about 180 x 180 km. A comparison of the JunoCam image from February 2024 with Galileo spacecraft imagery of the same area in November 1997 (grayscale insert) reveals
