Phys.org / Dust from a giant asteroid crash caused an ancient ice age

About 466 million years ago, long before the age of the dinosaurs, the Earth froze. The seas began to ice over at the Earth's poles, and the new range of temperatures around the planet set the stage for a boom of new species ...

Phys.org / Study of ancient climate suggests future warming could accelerate

The rate at which the planet warms in response to the ongoing buildup of heat-trapping carbon dioxide gas could increase in the future, according to new simulations of a comparable warm period more than 50 million years ago.

Medical Xpress / Learning to read boosts the visual brain

Reading is a recent invention in the history of human culture—too recent for dedicated brain networks to have evolved specifically for it. How, then, do humans accomplish this remarkable feat? As we learn to read, a brain ...

Medical Xpress / Promising drug candidate could stop malaria parasites at multiple stages

Redesigning molecules originally developed to treat the skin disease psoriasis could lead to an effective new drug against malaria, according to an international team of researchers. The team modified a class of molecules ...

Phys.org / Geophysicists challenge conventional view of the cause of porosity in weathered rock

New research published today in the journal Science Advances challenges the conventional view of how a vital and life-sustaining feature of weathered rock is created. Porosity, the void space found in rock, was traditionally ...

Phys.org / Greenland's growing 'ice slabs' intensify meltwater runoff into ocean

Thick, impenetrable ice slabs are expanding rapidly on the interior of Greenland's ice sheet, where the ice is normally porous and able to reabsorb meltwater. These slabs are instead sending meltwater spilling into the ocean, ...
