Ancient Solar Storm Reveals Vikings Were In North America Exactly 1,000 Years Ago

Most estimates of when the first Europeans set foot on American soil have relied heavily on information gleaned from Icelandic sagas – but a new study has pinpointed the Viking presence in North America to 1021 CE. This date now stands as the earliest known crossing of the Atlantic Ocean. It all comes down to a massive solar storm that occurred in 992 CE, leaving an uplift in radiocarbon production in wooden artifacts.

First Crab Found In Amber Still Fabulous At 100 Million Years Old

The first-ever true crab from the age of dinosaurs has been found preserved in amber. The crustacean, Cretapsara athanata, is around 100 million years, with the anatomy of its gills still intact. Their structure indicates that this crab enjoyed an amphibious or freshwater lifestyle, an evolutionary departure from its marine-dwelling ancestors. The amber was in a batch of commercial “raw” amber pieces gathered by Burmese miners and sold to a gemstone vendor at a fair in 2015.

Genetically Engineered Pig Kidney Successfully Transplanted Into Human In World First

In a world-first, US surgeons have successfully transferred a kidney taken from a pig into a braindead human patient with the permission of her family. This is a major step towards using animal organs in human transplantations. The team used an organ from a pig that had been genetically engineered in order to remove a sugar molecule known to play a significant role in rejection. It was not rejected by the host and functioned normally.

Astronomers Catch White Dwarf "Switching On And Off" For First Time

Astronomers have for the first time caught a star brightening before dimming again over the space of 30 minutes. The white dwarf has a companion from which it siphons hydrogen and helium. When it is actively accreting, the white dwarf is "on", becoming brighter. Then suddenly the accretion stops, and the white dwarf accretion turns off. Other white dwarf stars steal material and brighten over days or months – but for TW Pictoris this happens in just minutes.
