Research finds runoff from melting glaciers is giving climate change a boost
byMelting glaciers are one runaway symptom of global warming, but new research suggests that they might also be a contributing factor. Scientists have discovered evidence of a previously unknown vicious circle, whereby melted glacial water alters the chemistry on the surface of the ocean and drives further glacial melting, in turn accelerating the rise of sea […]

How plants avoid ‘sunburn’
byIf the ultraviolet radiation from the sun damages human DNA to cause health problems, does UV radiation also damage plant DNA? The answer is yes, but because plants can’t come in from the sun or slather on sunblock, they have a super robust DNA repair kit. Research finds that this powerful DNA repair system in […]

The planet-hunter telescope TESS launches today
byPlanet hunters have a new tool in their quest for planets like Earth: a space telescope called TESS, set to launch from Cape Canaveral today. Over the course of its two-year mission, TESS (Transiting Exoplanet Survey Satellite) will scan almost the entire sky, using four cameras to snap images of more than 200,000 stars. Astronomers anticipate […]

What’s new: A growing number of researchers believe while there may have been a main […]

Three ‘coronal holes’ appear on the sun as solar storm buffets Earth
byThree alarming-looking coronal holes have appeared on the surface of the sun – as a solar storm has buffeted our planet. But while coronal holes (which are only visible in certain wavelengths of light) look alarming, they’re actually quite common, and this week’s solar storm has been mild. NASA says that it spotted the holes […]

Global warming is making ocean heat waves longer, slowing down underwater currents
byA pair of scientific studies released this week pinpoint how climate change is impacting the world’s oceans. The first study notes that heat waves over the ocean have become longer and more frequent over the last century, harming marine life and coral reefs. The study, published in Nature Communications on Tuesday, found an increase of 54% in the number of […]

NASA studies how seasonal changes affect Plankton
byHampton, VA – Each new season brings change. Seasonal change on land is something that we’re familiar with and adjust to regularly. But what happens to billions of plankton in the ocean each season? How do they adjust to changing sunlight patterns and mixing of the water column? And what impact do these tiny critters have […]
