Plant life forms in the fossil record: When did the first canopy flowers appear?
(Geological Society of America) Most plant fossils are isolated organs, making it difficult to reconstruct the type of plant life or its ecosystem structure. In their study for GEOLOGY, published online on 28 Aug. 2014, researchers Camilla Crif and colleagues used leaf vein density, a trait visible on leaf compression fossils, to document the occurrence of stratified forests with a canopy dominated by flowering plants.

Antarctic sea-level rising faster than global rate
(University of Southampton) A new study of satellite data from the last 19 years reveals that fresh water from melting glaciers has caused the sea-level around the coast of Antarctica to rise by 2 cm more than the global average of 6 cm.

NASA sees Hurricane Cristobal racing through North Atlantic
(NASA/Goddard Space Flight Center) Satellite imagery shows Hurricane Cristobal racing through the North Atlantic on Friday, August 29 while losing its tropical characteristics.

NASA animation shows Hurricane Marie winding down
(NASA/Goddard Space Flight Center) NOAA's GOES-West satellite keeps a continuous eye on the Eastern Pacific and has been covering Hurricane Marie since birth. NASA's GOES Project uses NOAA data and creates animations and did so to show the end of Hurricane Marie.

Snails tell of the rise and fall of the Tibetan Plateau
(Geological Society of America) The rise of the Tibetan plateau -- the largest topographic anomaly above sea level on Earth -- is important for both its profound effect on climate and its reflection of continental dynamics. In this study published in GSA Bulletin, Katharine Huntington and colleagues employ a cutting-edge geochemical tool -- 'clumped' isotope thermometry -- using modern and fossil snail shells to investigate the uplift history of the Zhada basin in southwestern Tibet.

Managing coasts under threat from climate change and sea-level rise
(University of Southampton) Coastal regions under threat from climate change and sea-level rise need to tackle the more immediate threats of human-led and other non-climatic changes, according to a team of international scientists.

Not all phytoplankton in the ocean need to take their vitamins
(Canadian Institute for Advanced Research) Some species of marine phytoplankton, such as the prolific bloomer Emiliania huxleyi, can grow without consuming vitamin B1 (thiamine), researchers have discovered.

NASA sees a weaker Tropical Storm Marie
(NASA/Goddard Space Flight Center) When NOAA's GOES-West satellite captured an image of what is now Tropical Storm Marie, weakened from hurricane status on Aug. 28, the strongest thunderstorms were located in the southern quadrant of the storm.

NASA's TRMM analyzes Hurricane Cristobal
(NASA/Goddard Space Flight Center) NASA's Tropical Rainfall Measuring Mission or TRMM Satellite provided a look under the hood of Hurricane Cristobal as it continues moving north and paralleling the US East Coast. NASA's HS3 hurricane mission also investigated the storm. Cristobal is now close enough to the coast to trigger high surf advisories.

NASA's TRMM satellite adds up Cristobal's heavy rainfall in the Caribbean
(NASA/Goddard Space Flight Center) The Caribbean Islands of Turks and Caicos were drenched from Tropical Storm Cristobal before the storm moved north and intensified into a hurricane. NASA's TRMM satellite added up the rainfall and revealed the soaking those islands received.
