    Natural acids in soil could protect rice from toxic nanoparticles

    A dose of dirt could defend rice plants from the damaging effects of toxic nanoparticles.

    Acids naturally found in the organic matter of soil, collectively called humic acid, can protect rice seedlings from the cell damage and stunted root growth caused by copper oxide nanoparticles, researchers report April 13 in...

    Weather forecasting is getting a high-speed makeover

    In late January, a massive snowstorm drifted toward New York City. Meteorologists warned that a historic blizzard could soon cripple the Big Apple, potentially burying the city under 60 centimeters of snow overnight. Governor Andrew Cuomo took drastic action, declaring a state of emergency for several counties and shutting down the city that never sleeps. For the first time in its 110-year...

    Onshore hurricanes in a slump

    No major hurricanes have slammed into the coast of the United States since Hurricane Wilma in 2005. The gap in these hurricanes making landfall is the longest in recorded history and is incredibly rare, researchers report.

    Many hurricanes in recent years have reached Category 3 or above while out to sea, but...

    Low levels of lead linked to lower test scores in children

    Small doses of lead may have big impacts on reading and math scores, scientists report April 7 in Environmental Health.

    Researchers looked at third grade test scores and levels of lead in blood samples from 58,650 students in Chicago public schools. As little as 2...

    The moon is about as old as we thought it was

    Many, many moons ago, a proto-planet the size of Mars slammed into early Earth. In its wake, the collision left a planetary disk that formed the moon and sent bits of proto-planet flying into our solar system’s main asteroid belt. The collision occurred around 4.47 billion years ago, researchers report in the April 17 ...

    Oil from BP spill probably sprayed out in tiny drops

    Much of the oil that gushed into the Gulf of Mexico during the 2010 Deepwater Horizon oil spill may have shattered into droplets too small to rise to the surface.

    Droplets with an average diameter of about 80 micrometers would have formed as the oil violently rushed out of the well and into the crushing pressure of 1,500-meter-deep water,...

    Meeting of the Americas came early, study suggests

    North and South America may have hooked up 10 million years earlier than thought.

    Many scientists think that the seaway separating the two continents closed about 3 million years ago, sparking mass animal migrations and an ice age in the Northern Hemisphere. After analyzing crystals excavated from an ancient South American streambed, researchers...

    Tiny sea turtles are swimmers, not drifters

    It has long been thought that after sea turtles hatch and make their run for the sea, the tiny reptiles passively drift through the oceans, their destination driven by the currents, not the turtles themselves. No one really knew where the turtles went, and their early lives were nicknamed the “lost years” in recognition of human ignorance.

    Then...
