| Crack discovered in Earth's magnetic shield Posted: 03 Nov 2016 09:59 AM PDT The GRAPES-3 muon telescope recorded a burst of galactic cosmic rays of about 20 GeV, on 22 June 2015 lasting for two hours. The burst occurred when a giant cloud of plasma ejected from the solar corona, and moving with a speed of about 2.5 million kilometers per hour struck our planet, causing a severe compression of Earth's magnetosphere from 11 to 4 times the radius of Earth. It triggered a severe geomagnetic storm that generated aurora borealis, and radio signal blackouts in many high latitude countries. |
| Spiral growth: Feedback loop behind spiral patterns in plants uncovered? Posted: 03 Nov 2016 09:44 AM PDT For centuries, artists, biologists and mathematicians have been inspired by the recurring patterns of the plant world: the exquisite symmetry of flowers, the sweeping spirals of seeds, spines and leaves. How do plants create such amazing patterns? |
| Frog, toad larvae become vegetarian when it is hot Posted: 03 Nov 2016 08:52 AM PDT Climate change is currently one of the greatest threats to biodiversity, and one of the groups of animals most affected by the increase in temperature is amphibians. A team of scientists studied how heat waves affect the dietary choices of three species of amphibian found on the Iberian Peninsula: the European tree frog, the Mediterranean tree frog and the Iberian painted frog. |
