Boulder, Colo., USA - In Cerro Colorado, located in the Ica Desert of Peru, sedimentary sequences dating back nine million years have been found to host the fossil skeletons of hundreds of marine vertebrates. In 2008, remains of a giant raptorial sperm whale, Livyatan melvillei, were discovered at this site. In September 2014, the same international team of researchers, guided by Giovanni Bianucci from Pisa University (Italy), found a partial skeleton of a mysticete whale in a rock boulder.

Humans utilise forests and watercourses in a way that depletes ecosystem habitats, biodiversity and ecosystem services. Many areas are restored to break the trend, but to succeed you need to consider not only the ecosystem in mind, but also surrounding ecosystems. This according to researchers in Umeå in Sweden in an article published in BioScience.

In the first large-scale and comprehensive study on the impacts of transporting honey bees to pollinate various crops, research from North Carolina State University shows that travel can adversely affect bee health and lifespan. Some of these negative impacts may be reduced by moving bee colonies into patches with readily available food or by providing supplemental nutrition when there are few flowers for honey bees to visit, the researchers say.

Earth's climate interacts with so called surface processes - such as landslides or river erosion - and tectonics to shape the landscape that we see. In some regions, the sheer force of these processes has led scientists to believe that they may even influence the development of tectonics. An international team of researchers headed by the Cologne-based geographer Dr. Georgina King have now disproved this assumption. The results of their study, "Northward migration of the eastern Himalayan syntaxis revealed by OSL-thermochronometry," will appear in Science on 19 August 2016.

Nearly half of the world population is fed by the industrial N2 fixation, i. e., the Harbor-Bosch process. Although exergonic in nature, NH3 synthesis from N2 and H2 catalyzed by the fused Fe has to be conducted at elevated temperatures and high pressures. It consumes over 1% of the world's annual energy supply. Developing efficient catalysts that enable NH3 synthesis under mild conditions is a grand scientific challenge and is of great practical need.

For the first time in the world, a research group led by Osaka University, Japan, clarified the crystal structure of hydrogen sulfide in its superconducting phase at the high temperature of -70°C. This was achieved by conducting a combination of experiments at one of the world's largest synchrotron radiation facilities, SPring-8 in Japan. These results mark a huge step towards developing room-temperature superconductors, which may provide promising solutions to energy problems.

Parents who directly and actively engage their children in healthy living behaviour - instead of passively 'supporting' the behaviour - are significantly more likely to see their kids meet Canadian guidelines when it comes to physical activity, healthy eating and screen time, new research from Public Health Ontario (PHO) has found.

A new Yale-led study published in the journal Nature Communications sheds light on the surprising role that haze in China plays in promoting the urban heat island effect [UHI], a process whereby city centers tend to be significantly warmer than surrounding rural areas.

In an extensive interview published online this week, the winners of the 2016 Kavli Prize in Astrophysics discuss their 40-year effort to detect gravitational waves, the elusive ripples in the fabric of space-time that Albert Einstein so boldly predicted. The discussion, with physicists Kip Thorne and Rainer Weiss, covers the challenges of eavesdropping on gravitational waves, why their discovery has captured the world's imagination, and what the future holds for astronomy.

Researchers from North Carolina State University, the National Institute of Standards and Technology (NIST) and Oak Ridge National Laboratory (ORNL) have developed a novel approach to materials characterization, using Bayesian statistical methods to glean new insights into the structure of materials. The work should inform the development of new materials for use in a variety of applications.
