If frequency of occurrence were an indicator, we might conclude that thanksgiving is important and praise-giving is twice as important! More...
Pluto's Craterless Plains Look Young
Earlier this year, New Horizons flew past dwarf planet Pluto and its sister Charon, rapidly capturing data. That information continues to trickle in, revealing a surprisingly smooth heart-shaped plain called "Tombaugh Regio." The countless craters expected from billions of years' worth of impacts are nowhere to be found. More...
Fossil Shrimp Brains Look Modern
Cambrian rocks are supposed to represent a time about 500 million years ago when ancient muds buried some of the first creatures that evolved on Earth. Today's array of life forms supposedly emerged from those "simpler" beginnings. But intriguing Cambrian discoveries, including newly described arthropod fossils from China, keep clashing with these out-of-touch ideas. More...
Unexpected Oxygen on Young-Looking Comet
The European Space Agency's Rosetta probe travelled all the way to comet 67P/Churyumov-Gerasimenko to collect unprecedented cometary details. The space probe keeps sending unexpected particulars about the comet—particulars with implications far beyond the comet itself. More...
2015 Nobel Prize Highlights Cell Repair Mystery
Three scientists were awarded the 2015 Nobel Prize in Chemistry for uncovering how human cells repair their own DNA. DNA repair mechanisms keep us alive, and understanding them undergirds a fuller comprehension of how cells work and fend off the disastrous consequences of too many mutations. The research of these three men implies that cells have always used DNA repair mechanisms, thus uncovering evolutionary mysteries that have not yet found sensible solutions. More...
Amazing Design Structures in Long-Necked Dinosaurs
The 75th annual meeting of the Society of Vertebrate Paleontology provided glimpses into the latest research on fossils of all kinds, including those long-necked dinosaurs called sauropods. One presentation revealed amazing structures that demonstrated the feasibility and efficiency of design that could hold 30-foot-long necks aloft. More...
Amazing Sauropod Neck Design in 'Cervical Ribs'
When someone says "ribs," people immediately think of those organ-protecting bones that wrap around a thorax. Well, cervical ribs are different, and cervical ribs on extinct long-necked dinosaurs were very different. They ran the whole length of certain sauropods' necks. Each rib attached to a neck vertebra, and each rib stretched across the length of three total vertebrae. Were these cervical ribs an evolutionary happenstance, or did they serve some kind of function as though created on purpose? More...
