Phys.org / Ancient hobbit-like humans may have survived on meat left behind by Komodo dragons

Arguably one of the most curious ancient human relatives is Homo floresiensis, a 3-foot-tall species that lived on the Indonesian island of Flores and has been nicknamed "hobbit" for its diminutive stature. Even though they ...

Phys.org / Hummingbirds speed up pineapple family's evolution

Hummingbirds make bromeliad plants split into new species twice as fast as other pollinators do, scientists at the University of Reading have found. The research team gathered records of which animals pollinate 403 types ...

Phys.org / Chemists capture structure of the elusive borylnitrene trapped in a crystal using X-ray

Nitrenes are the ghosts of synthetic chemistry, formed in an instant and gone just as quickly, rearranging into something entirely different. These highly reactive intermediates are widely used in synthesis, yet remain notoriously ...

Phys.org / Storms impact the architecture of webs and the survival of spiders

In the dense forests of the Ecuadorian Andes, the survival of a spider relies not only on its ability to prey on insects but also on its capacity to resist a threat coming from the skies. A new study revealed that the heavy ...
