Climate and carbon cycle trends of the past 50 million years reconciled — ScienceDaily

Predictions of future climate change require a clear and nuanced understanding of Earth’s past climate. In a study published today in Science Advances, University of Hawai’i (UH) at Manoa oceanographers fully reconciled climate and carbon cycle trends of the past 50 million years — solving a controversy debated in the scientific literature for decades. Throughout […]

‘Old murderer’ bug died 50 million years ago, fossilized with its penis intact

The broken parts of a tiny Cretaceous insect’s minuscule genitals were recently put back together after spending more than a decade apart.  Researchers have described a new species of assassin bug from a remarkably well-preserved fossil dating to around 50 million years ago. At the time of the fossil’s discovery in Colorado in 2006, it […]

Lizzie Borden’s home, site of brutal axe murders, could be yours for $2 million

The home where the 19th-century accused killer Lizzie Borden allegedly murdered her father and stepmother with a hatchet in 1892 is for sale … as a bed-and-breakfast. Borden was accused and tried of the gruesome double murders after the bodies were discovered in the house on the morning of Aug. 4, 1892, in Fall River, […]

Conductive nature in crystal structures revealed at magnification of 10 million times

University of Minnesota Professor K. Andre Mkhoyan and his team used analytical scanning transmission electron microscopy (STEM), which combines imaging with spectroscopy, to observe metallic properties in the perovskite crystal barium stannate (BaSnO3). The atomic-resolution STEM image, with a BaSnO3 crystal structure (on the left), shows an irregular arrangement of atoms identified as the metallic […]
