  • Pattern of light from early universe detected by NASA

    Does light leave tracks? How is it possible for scientists to observe light that originated billions of years ago? These are questions that intrigue us and we are amazed when scientists figure out a way to observe what to most of us is un-observable. The journey of light from the very early universe to modern…

  • Freshwater biodiversity

    The biodiversity of our rivers, lakes, and ponds has gone largely un-addressed in our efforts to predict the impacts of land development. Planners look at increased runoff and the potential for downstream flooding, and on pollutant discharges and contamination issues. The biodiversity of freshwater bodies is also impacted buy development and agricultural activities, but until…

  • New UN climate change report

    The United Nations Intergovernmental Panel on Climate Change (IPCC) has been leading the effort in collecting scientific evidence of climate change and in looking to answer the most important question, is it caused by human activity? Some argue that it is caused mostly by natural variability, and non-human factors. The new IPCC report, released this…

  • Space weather

    The weather is important to everyone. Will it rain today, will I need a jacket? But what is space weather? Is there really “weather” in outer space? Isn’t space almost a perfect vacuum? UCLA has been studying this for some time and recently completed a study that sheds important light on space weather. Solar storms…

  • Earth’s radiation belts more complicated than thought

    The Earth is circled by belts of electrons and ions that have been the subject of study for decades. Now, a new study casts light on details of these radiation belts that eluded scientists. Since the discovery of the Van Allen radiation belts in 1958, space scientists have believed these belts encircling the Earth consist…

  • Secrets of Earth’s inner core

    The Earth has a solid iron core. That has been known since the days of Edward Halley, the discoverer of Halley’s comet. The inner core also rotates, but details of its rotation have defied explanation, until now! Scientists at the University of Leeds have solved a 300-year-old riddle about which direction the centre of the…

  • New insight on how tropical forests capture carbon

    Tropical forests are important globally in removing carbon from the atmosphere. It has been assumed that the tress were the mechanism that made this work. New research from Princeton University has shed insight on the importance of bacteria that co-exist with the trees have in absorbing atmospheric carbon. A unique housing arrangement between a specific…

  • New study of the Arctic Ocean finds alarming increase in acidity

    If you ever had a marine aquarium (or a swimming pool) you know that it is very important to keep the level of acidity (ph) within a narrow range for optimum results. In the case of the pool, to minimize corrosion of the metal parts in a heater and to reduce damage to the pool…

  • Happiness found to be a good target of policy

    Everyone yearns to be happy. Some think obtaining the next hot gadget or cell phone will do it. Others the new hot sports car. For others, a warm bed and food for their family will bring happiness. But what does our yearning for happiness have to do with government policy? How can governments increase our…
