Jessica Oster and her colleagues have shown that the analysis of a stalagmite from a cave in north east India can detect the link between El Nino conditions in the Pacific Ocean and the Indian monsoon.
Genetic material from fungi collections at Purdue University and the Royal Botanic Gardens, Kew, helped a team of researchers resolve the mushroom 'tree of life,' a map of the relationships between key mushroom species and their evolutionary history that scientists have struggled to piece together for more than 200 years.
Disaster investigators and emergency personnel may find themselves better able to assess and respond to terrorist attacks and industrial accidents with the aid of a new computational tool that determines the energy from explosions near the Earth's surface.
A study carried out in Arizona by an international research team from Poland and Korea revealed that the Mexican Jays (Aphelocoma wollweberi) distinguish between heavier and lighter peanuts without opening the nuts. The birds do it by shaking the nuts in their beaks, which allows them to 'feel' nut heaviness and to listen to sounds produced by peanuts during handling.
Animals with large brains are considered to be more intelligent and more successful than those with smaller brains. Researchers from the Vetmeduni Vienna and Stockholm University have provided the first experimental evidence that large brains provide an evolutionary advantage. Large-brained female fish have a higher survival rate than those with small brains when faced with a predator, although brain size surprisingly did not influence male survival. The results were published in Ecology Letters.
Increasing public knowledge and understanding about energy issues is vital if improved energy-saving behaviors are to be encouraged among individuals and organizations, a study conducted at Plymouth University suggests.
Study shows how heavy-ion induced atomic-scale defects in iron-based superconductors 'pin' potentially disruptive quantum vortices, enabling high currents to flow unimpeded. The study opens a new way forward for designing and understanding superconductors that can operate in demanding high-current, high magnetic field applications, such as zero-energy-loss power transmission lines and energy-generating turbines.
The GOES-R satellite, slated to launch in 2016, is ready for environmental testing. Environmental testing simulates the harsh conditions of launch and the space environment once the satellite is in orbit.
The Moderate Resolution Imaging Spectroradiometer on NASA's Aqua satellite collected this natural-color image which detected dozens of fires burning in southwestern Africa on May 21, 2015.
Researchers have developed a model to assess how dams affect the viability of sea-run fish species that need to pass dams as they use both fresh and marine waters during their lifetimes. NOAA's Northeast Fisheries Science Center and Greater Atlantic Regional Fisheries Office have partnered on this project to test how varying passage efficiency at dams related to survival rates for these species, using a model of endangered Atlantic salmon as a case study.
