Newly discovered ancient arthropod lived hundreds of millions of years ago
The Burgess Shale Formation, in the Canadian Rockies of British Columbia, is one of the most famous fossil locations in the world. A recent Palaeontology study introduces a 508 million year old (middle Cambrian) arthropod -- called Yawunik kootenayi -- from exceptionally preserved specimens of the new Marble Canyon locality within the Burgess Shale Formation.

X-raying the past: New insights into the life of extinct marine creatures
Using state-of-the-art imaging techniques, palaeontologists at the Ruhr-Universität Bochum have been examining extinct marine creatures. Quantitative analyses provide new evidence that ammonites were able to swim using their shell -- very much like the recent nautilus. For the purpose of the study, the researchers, together with partners from the industry, developed an evaluation process for high-res CT images. The science magazine 'RUBIN' reports about the results.

New study hints at spontaneous appearance of primordial DNA
The self-organization properties of DNA-like molecular fragments four billion years ago may have guided their own growth into repeating chemical chains long enough to act as a basis for primitive life, says a new study by the University of Colorado Boulder and the University of Milan.

Expedition will sample crater left by dinosaur-killing asteroid
An international research team is formalizing plans to drill nearly 5,000 feet below the seabed to take core samples from the crater of the asteroid that wiped out the dinosaurs. The group met last week in Merida, Mexico, a city within the nearly 125-mile-wide impact site, to explain the research plans and put out a call for scientists to join the expedition planned for spring 2016.

EARTH: Kamikaze typhoons spared Japan from Kublai Kahn
In a small lake along the Japanese coast, scientists have found evidence of turbulent waters centuries ago. These telltale signs of severe weather in the geologic record support the legend of the two kamikaze typhoons that protected Japan from Mongol invasion.

University of Nebraska-Lincoln, US Navy develop next-gen temperature sensor to measure ocean dynamics
Temperature is one of the key variables in studying the ocean. A fiber-optic sensor developed by University of Nebraska-Lincoln engineers and the US Naval Research Laboratory can register significantly smaller temperature changes, roughly 30 times faster than existing commercial sensors.

Northern coastal marshes more vulnerable to nutrient pollution
Salt marshes at higher latitudes, including those in densely populated coastal regions of New England and Europe, are more vulnerable to the effects of eutrophication, which, if left unchecked, can trigger intense overgrazing by marsh herbivores that can destabilize marshes and reduce their ability to defend shorelines from erosion. Geography and evolution both play roles in making these marshes more susceptible to nutrient loading and overgrazing than their counterparts in the tropics.

How many organisms do live in this aquatic habitat?
A new measurement method has been developed at Hiroshima University, Japan. The aim of this method is to estimate the distribution of aquatic animals using droplet digital polymerase chain reaction in order to quantify the number of target DNA copies present. This technique can be applied for habitat research on rare or non-native species in the field.

New evidence shows carbon's importance to ocean life's survival 252 million years ago
A new study led by UT Arlington Earth & Environmental Scientists shows for the first time how carbon offered a mode of survival for some ocean life after one of the greatest mass extinctions in the history of Earth.

NASA catches a tropical cyclone's birth in 3-D
Tropical Cyclone 05W was born in the Northwestern Pacific Ocean on April 3 west of the island of Pohnpei when the GPM satellite passed over it and analyzed its rainfall rates. That GPM data was made into a 3-D image that showed some high thunderstorms northwest of its center.

NASA's ISS-RapidScat: Typhoon Maysak's strongest winds tightly wound
The RapidScat instrument that flies aboard the International Space Station saw Typhoon Maysak's strongest winds wrapped tightly around its center, extending outward to over 30 miles from the eye. Maysak weakened as a result of increasing wind shear.

New study finds a natural oil dispersion mechanism for deep-ocean blowout

Ocean-scale dataset allows broad view of human influence on Pacific coral reef ecosystems
A study published today by scientists at the University of Hawai'i at Manoa, the National Oceanic and Atmospheric Administration, and the University of Victoria in the journal PLOS ONE draws on data from nearly 40 islands and atolls across the central and western Pacific, including 25 unpopulated islands, to investigate the relative influence of environmental variation and human presence on reef fish assemblages. The resulting message is sobering.

Story tips from the Department of Energy's Oak Ridge National Laboratory, April 2015
By studying fish and invertebrates in a creek with known mercury contamination, researchers are gaining a better understanding of the relationship between the toxin in the stream and bioaccumulation in organisms. While mercury concentrations in East Fork Poplar Creek in Oak Ridge, Tenn., have decreased significantly over the last 30 years, levels in tissue from fish have remained the same or increased. To understand why, a team led by Monica Poteat of Oak Ridge National Laboratory is examining the intricacies of the food chain and the biodiversity of the stream at locations about 10 kilometers apart.
