Phys.org / How play and social connection may help some dogs understand words

Some dogs are seemingly more talented than others. So-called gifted word learners (GWL) are rare canines that can rapidly learn the names of toys, a skill that most dogs don't possess. To understand why this is so, researchers ...

Phys.org / Global warming is speeding breakdown of major greenhouse gas, research shows

Scientists at the University of California, Irvine have discovered that climate change is causing nitrous oxide, a potent greenhouse gas and ozone-depleting substance, to break down in the atmosphere more quickly than previously ...

Phys.org / New model predicts the melting of free-floating ice in calm water

A pair of US researchers have developed a new model to tackle a deceptively simple problem: how a small block of ice melts while floating in calm water. Using an advanced experimental setup, Daisuke Noto and Hugo Ulloa at ...

Phys.org / Reproduction in space, an environment hostile to human biology

As commercial spaceflight draws ever closer and time spent in space continues to extend, the question of reproductive health beyond the bounds of planet Earth is no longer theoretical but now "urgently practical," according ...

Phys.org / Supermassive black holes sit in 'eye of their own storms,' studies find

Gigantic black holes lurk at the center of virtually every galaxy, including ours, but we've lacked a precise picture of what impact they have on their surroundings. However, a University of Chicago-led group of scientists ...

Phys.org / One-of-a-kind 'plasma tunnel' recreates extreme conditions spacecraft face upon reentry

Picture a spacecraft returning to Earth after a long journey. The vehicle slams into the planet's atmosphere at roughly 17,000 miles per hour. A shockwave erupts. Molecules in the air are ripped apart, forming a plasma—a ...

Phys.org / Two huge hot blobs of rock influence Earth's magnetic field, study reveals

Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion km into space, the deepest we have ever gone below our feet is just over 12 km. Consequently, little ...
