That there's an ongoing component shortage in the electronics industry isn't news, particularly to PC gamers. Memory maker Micron has some words of encouragement for those who are still struggling to find the parts they need for a PC build at less than usurious pricing: Supply shortages are likely to be 'largely resolved' over the next few months. 'There have been extensive efforts to understand the environmental conditions and formative mechanisms associated with valley network incision, with past global studies primarily proposing formation by surface runoff (rainfall or snowmelt), groundwater discharge at the heads of valleys, and/or subglacial drainage from large ice sheets,' the paper, published in Nature this week, said. The research sheds light on the formation of landforms created in the 'valley network-forming era' of Martian history that ended between 3.5–3.7 billion years ago. In a paper that prompts a rethink of the Red Planet's ancient landscape, researchers from The University of Texas at Austin used data from the Mars Global Surveyor (MGS), a spacecraft that was launched in 1996, to probe the assumptions that water erosion on Mars is largely down to a continuous flow in its valleys. Scientists studying Mars now reckon flooding from lakes contributed to around a quarter of the planet's land erosion and not just continuous flows of water that had been assumed to be the cause.
