Today marks the one year anniversary of Pokémon GO’s worldwide release that sent crowds hiking through parks, meandering into streets and walking for miles in search of Pokémon, those cute little digital characters that appear in real locations on your smartphone.

When it comes to the distant universe, even the keen vision of NASA's Hubble Space Telescope can only go so far. Teasing out finer details requires clever thinking and a little help from a cosmic alignment with a gravitational lens.

Climate evolution shows some regularities, which can be traced throughout long periods of earth’s history. One of them is that the global average temperature and the carbon dioxide concentration in the atmosphere usually go hand-in-hand. To put it simple: If the temperatures decline, the CO2 values also decrease and vice versa.

As Tropical Depression 4 was getting organized in the central Atlantic Ocean the Global Precipitation Measurement Mission or GPM satellite peered into the storm and measured rainfall within. The system became Tropical Depression 4 on July 6.

Structural geologist Michele Cooke calls it the “million-dollar question” that underlies all work in her laboratory at the University of Massachusetts Amherst: what goes on deep in the earth as strike-slip faults form in the crust? This is the fault type that occurs when two tectonic plates slide past one another, generating the waves of energy we sometimes feel as earthquakes.

Could cellulosic biofuels – or liquid energy derived from grasses and wood – become a green fuel of the future, providing an environmentally sustainable way of meeting energy needs? In Science, researchers at the U.S. Department of Energy-funded Great Lakes Bioenergy Research Center say yes, but with a few important caveats.

The Swedish-based carmaker, Volvo, will build only electric or hybrid-electric cars beginning in 2019, making it the first big auto company to abandon conventional gasoline-powered engines. 

The legendary auto manufacturer, now a wholly owned subsidiary of a Chinese company, had earlier set a goal of selling one million electric cars and hyrids by 2025. “This is how we are going to do it,” President and CEO Hakan Samuelsson said in a statement. 

A research group from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences recently reported the development of a new technology to boost performance of direct methanol fuel cells (DMFCs) using high-concentration methanol as fuel, shedding some light on the design of clean and affordable alternative energy sources for portable electric devices. 

When methanol, the fuel of DMFCs, crosses over from the anode to the cathode through the proton exchange membrane (PEM), fuel cell performance is significantly degraded, creating a major problem for the commercialization of DMFCs. Commonly, scientists use various strategies to improve DMFC performance at high concentrations of methanol. These include improving the fuel-feed system, membrane development, modification of electrodes, and water management. 

Reporting this week (Wednesday 5 July) in the journal Nature, an international team of researchers led by British Antarctic Survey (BAS) explains that wind-driven incursions of warm water forced the retreat of glaciers in West Antarctica during the past 11,000 years. These new results enable researchers to better understand how environmental change may impact future sea-level rise from this climate-sensitive region.

Tiny Japanese quail eggs are a small niche market in the United States, but they’re a big business in Brazil where they are sold fresh in grocery stores in egg cartons that hold 30 of the small, speckled delicacies, and are a hard-boiled staple on restaurant salad bars. Recent research from the University of Illinois helps Brazilian producers understand the birds’ behavior under wind and temperature variables and suggests environmental changes to boost their egg-laying productivity.
