On the origin of academic traditions—and some alternatives for debate

The field of science aims to be objective, repeatable and justified in its choices and methods. These principles are what distinguish accepted scientific findings from pseudo-science. Yet the experience of learning and working ...

Investigations of the polysomatism of antigorite under pressure

Antigorite is a type of serpentine, which is the most abundant hydrated mineral on the Earth. It is widely believed that this mineral is the main carrier of water deep into the Earth in subducting oceanic plates. It has a ...

Researchers discover Earth and space share the same turbulence

In a paper published in Geophysical Research Letters, researchers have discovered that the turbulence in the thermosphere exhibits the same physical laws as the wind in the lower atmosphere. Furthermore, wind in the thermosphere ...

New GPS-based method can measure daily ice loss in Greenland

When the ice sheet in Greenland melts, as it has done increasingly in recent years, the bedrock beneath moves slightly.

Making ultra-fast electron measurements in multiple directions to reveal the secrets of the aurora

The energetic electrons that drive the aurora borealis (the northern lights) have a rich and very dynamic structure that we currently do not fully understand. Much of what we know about these electrons comes from instruments ...

Q&A: Clarifying the megathrust earthquake mechanism

There is a 70-80% chance that the Nankai Trough Megathrust Earthquake will occur in the next 30 years. It is predicted to cause more extensive damage than the 2011 Great East Japan Earthquake and fatalities may exceed 320,000.

A 3D view into chaos: Researchers visualize temperature-driven turbulence in liquid metal for the first time

Experiments with liquid metals could not only lead to exciting insights into geophysical and astrophysical flow phenomena, such as atmospheric disturbances at the rim of the sun or the flow in the Earth's outer core, but ...

Emergency atmospheric geoengineering wouldn't save the oceans

Climate change is heating the oceans, altering currents and circulation patterns responsible for regulating climate on a global scale. If temperatures dropped, some of that damage could theoretically be undone.
