As molten rock gathers underground, a huge volcanic field in Chile is the fastest-rising land on Earth. The biggest eruptions at Laguna del Maule, if they happened today, would change our climate and planet. Scientists are racing to understand a strange unrest in a bizarre landscape.
And how did it traverse 460 kilometers of ocean? Apparently by crossing a narrow band of ice during the last Ice Age. A new study echoes evolutionary giants Darwin and Wallace and highlights the role of sea level in animal migration.
Finally, an A-to-Z encyclopedia of ionizing radiation — but one that omits key topics.
“Yes, but…” is the word from the frontiers of physics. The world’s largest atom smasher has blasted protons against each other with such enormous energy that they have — apparently — appeared in the debris of decaying particles. At last, matter can have mass!
How do patents work? What is “new, non-obvious and useful”? What will happen after the biggest change in patent law in 60 years?
How do homing pigeons find their way on their amazing migrations? For a decade, scientists thought iron-bearing nerve cells in the beak can detect Earth’s magnetic field. But those iron granules are in immune cells. So how do the birds do it?
Sometimes, scientists feel the need to leave the lab and warn the public about onrushing hazards. Rowland warned about ozone, but others are warning about warming. Does scientific culture encourage or hinder going public? Does the helpful response to ozone depletion suggest we’ll succeed in confronting global warming?
Volcanic eruptions are unpredictable, but here’s a new view of the historic eruption of a Mediterranean monster. About 3,500 years ago, Santorini’s eruption left a giant caldera and 60-meter layers of pumice. A new study of tiny crystals tracks the movement of molten magma before the cataclysm.
In African savannas, cattle graze the same grass as zebras, elephants and gazelles. Obviously, wildlife are stealing food from the mouths of cattle, and from the people who depend on cattle. But new data show that in the wet season, grazing wildlife actually benefit cattle!
Hitting the road? What could be more enlightening than gawking at a cave, exploring a desert, or eyeballing the largest telescope in the world? Need proof that science is not just books and websites or equations and software? Get moving!
Experiment finds Earth “dragging” spacetime, as Einstein predicted. Einstein knew his physics. Bending light, gravity lenses, shifting spacetime, spinning neutron stars: he called them all.
Earth’s orbit subtly changes over thousands of years, in complex cycles that affect the timing and delivery of sunlight to various regions of the globe. Climatologists have said that when this “Milankovitch cycle” warms the Arctic, it somehow warms the Antarctic. A new study finds that the cycle acts more directly.
Three gross “biotherapies”: Leeches suck blood after surgery. Maggots clear dead tissue from wounds. Parasitic worms fight ulcerative colitis.
A federal court has thrown the field of embryonic stem cell research into confusion. Last week, research that destroys embryos could not get federal bucks — even if those embryos were doomed or destroyed years ago. This week, it can. How is the legal yo-yo affecting researchers — and desperate patients?
