Using the Dark Energy Camera (DECam) on the Víctor M. Blanco 4-m Telescope at Cerro Tololo Inter-American Observatory in Chile, astronomers have captured this image of the grand design spiral galaxy NGC 1566. This image from the Dark Energy Camera on the Víctor M. Blanco 4-m Telescope at Cerro Tololo Inter-American Observatory shows NGC 1566, a grand-design spiral galaxy some 70 million light-years...

Using the Framing Camera (FC) and the Visible and Infrared Spectrometer (VIR) aboard NASA’s Dawn spacecraft, planetary researchers have spotted bright brine residues and organics in the Urvara basin, one of the largest impact structures on the dwarf planet Ceres. The results strengthen the hypothesis that Ceres is and has been a geologically active world even in recent epochs, with salts and organic-rich...

In a new paper published this week in the journal Science Advances, paleoanthropologists report hominin fossils from Grotte Mandrin in France that reveal the presence of anatomically modern Homo sapiens in Europe between 56,800 and 51,700 years ago. The discovery indicates that the movement of modern humans into Europe and the overlap with Neanderthals is more complex than previously thought. View...

Dearc sgiathanach had an estimated wingspan of between 1.9 and 3.8 m (6.2-12.5 feet), roughly the size of the largest flying birds today (e.g., wandering albatross). An artist’s impression of the Middle Jurassic pterosaur Dearc sgiathanach. Image credit: Natalia Jagielska. Pterosaurs were the first vertebrates to evolve flight and include the largest flying animals in Earth history. While some...

Scientists have described a new species of the Neotropical orchid genus Maxillaria from cloud rainforests of northern Ecuador. Maxillaria anacatalinaportillae. Image credit: Hugo Medina. The genus Maxillaria, abbreviated as Max in the horticultural trade, belongs to one of the most diverse and species-rich groups of orchids. Depending on the applied classification, it counts from approximately 420,...

Physicists at the University of Chicago have demonstrated formation of a new kind of quantum object — dubbed a ‘domain wall’ — in a Bose-Einstein condensate. Their result can help scientists better understand exotic quantum particles and could suggest avenues for new technologies in the future. A ‘domain wall’ in this image is the lighter line between two groups of atoms. Image...

A team of scientists from Australia, Italy, Poland and Switzerland has examined the association between meat intake and life expectancy at a population level based on ecological data published by the United Nations agencies. You et al. shows that meat intake is positively associated with life expectancy at national level; the underlying reasons may be that meat not only provides energy but also complete...

Insecticide resistance and rapid pest evolution threatens food security and the development of sustainable agricultural practices, yet the evolutionary mechanisms that allow pests to rapidly adapt to control tactics is unclear. The Colorado potato beetle (Leptinotarsa decemlineata) has evolved resistance to over 50 different insecticides, making the insect a super-pest that wreaks havoc on potatoes...

Calcium silicate perovskite (CaSiO3) is arguably the most geochemically important phase in the Earth’s lower mantle, because it concentrates elements that are incompatible in the upper mantle. No one has ever successfully retrieved this high-pressure compound from the lower mantle before. This is because CaSiO3-perovskite is ‘unquenchable,’ meaning that it cannot retain its structure after...50th Birthday Shirts for Men - Vintage 1972 Aged to Perfection -
