Phoenix Mars Lander finds surprises about red planet's watery past Liquid water has interacted with the Martian surface throughout Mars' history, measurements by NASA's Phoenix Mars Lander suggest. The findings also suggest that liquid water has primarily existed at temperatures near freezing, implying hydrothermal systems similar to Yellowstone's hot springs on Earth have been rare on Mars throughout its history. Strategy discovered to prevent Alzheimer's-associated traffic jams in the brain Amyloid beta proteins, widely thought to cause Alzheimer's disease, block the transport of vital cargoes inside brain cells. Scientists have discovered that reducing the level of another protein, tau, can prevent amyloid beta from causing such traffic jams. Chemical engineer's work could lead to improved DNA analysis DNA analysis is poised to experience a significant advancement thanks to the work of a chemical engineer who has discovered a way to achieve more effective separation of DNA fragments. Improvement in prediction of blood clots in cancer patients For cancer patients, who have an increased risk of developing venous thromboembolism due to a hyperactive blood coagulation system, there is now an enhanced risk model to predict their chance of developing blood clots, according to a recent study. Energy technologies not enough to sufficiently reduce carbon emissions, expert concludes Current energy technologies are not enough to reduce carbon emissions to a level needed to lower the risks associated with climate change, a physicist concludes in a new evaluation.
