Astronomers confirm the existence of small, hot and likely rocky planets by observing the subtle gravitational wobbles of the star they orbit Researchers supported by the U.S. National Science Foundation have discovered four tiny exoplanets orbiting Barnard’s star, a red dwarf at the center of the nearest single-star system to Earth. Using a specialized […]
New research examining 11,700 years of bowhead whale persistence throughout the Arctic projects that sea ice loss due to climate change will cause their habitat to severely contract by up to 75 per cent. An international team led by researchers from the University of Adelaide and the University of Copenhagen reconstructed an 11,700-year ecological baseline […]

There’s no one-size-fits-all approach when it comes to photovoltaic systems. Existing models can help users evaluate alternatives, and a new study looks at how effective such models are in northern climates. Photovoltaic, or PV, systems use solar panels to generate electricity from the sun’s energy. Accurate predictions about panel effectiveness are critical for the design, […]
