The Electronics Cooling System 400 Million Years in the Making





Over hundreds of millions of years of evolution, water-repellant skin has enabled tiny insects, called springtails, to breathe through their skin without suffocating in damp soil flooded by rainwater. More recently, such natural engineering has inspired a new approach to cooling new generations of miniaturized electronic devices. The secret of the springtail’s skin is tiny surface compartments that contain sharp edges: a physical design that resists the advance of liquids and can help contain the flow of liquids. Researchers in the United States and South Korea adapted this idea in a “porous membrane” design that could someday keep electronic systems from overheating through evaporative cooling. The porous membrane consists of tiny liquid-filled pillars that rely upon the sharp-edged trick to keep the liquid contained, even as the open ends of the pillars allow for liquid evaporation to get rid of excess heat.



Samsung Electronics rejects 2018 lobbying allegations




Broadcaster SBS has reported that a prosecution investigation into the corruption scandal that led to the downfall of former South Korean President Park Geun-hye had uncovered e-mails linking the tech giant to efforts to secure votes for Pyeongchang’s third bid to host the Games. SBS said it had obtained copies of e-mails between Samsung officials and Papa Massata Diack, who has been accused by France’s financial prosecutor of being part of a corruption racket involved in determining the Olympic host cities.
