New study explores functionality in aquatic ecosystems

The functions of water-dominated ecosystems can be considerably influenced and changed by hydrological fluctuation. The varying states of redox-active substances are of crucial importance here. Researchers at the University ...

New weather warning gauge for Australia

Australia, the driest inhabited continent, is prone to natural disasters and wild swings in weather conditions—from floods to droughts, heatwaves and bushfires.

Dust storms and valley fever in the American West

Valley fever is a dangerous threat to human health—and cases are on the rise in the arid southwestern United States, as wind from increasing dust storms can transport the fungal spores that cause the disease. Valley fever ...

New indicator for oxygen levels in early oceans developed

Oxygen is essential for the development of higher life. However, it was hardly present in the oceans of the young Earth. It was not until the evolution of photosynthetic bacteria that the oceans saw a significant increase ...

A deep reservoir of primordial helium in the Earth

Noble gases, including helium, neon, and argon, are characterized by high chemical inertness which causes low reactivity with other materials and high volatility. Among them, 3He, 20Ne, and 36Ar are particular isotopes which ...

Lifestyle changes to keep the world from warming up

Scientists widely agree that we must limit global warming to 1.5 degrees Celsius to avoid catastrophic climate impacts. Environmental scientist Laura Scherer investigates how we should change lifestyles to achieve this temperature ...

Climate change: How bad could the future be if we do nothing?

The climate crisis is no longer a looming threat—people are now living with the consequences of centuries of greenhouse gas emissions. But there is still everything to fight for. How the world chooses to respond in the ...

What are waterspouts, and how do they form?

Waterspouts are extraordinary, impressive weather events. Observers describe them as looking like "the start of an alien invasion" and post their snaps across social media.

Methane nibbling bacteria are more active during summer

Bacteria that thrive on methane released from the ocean floor are an important barrier preventing the greenhouse gas from reaching the atmosphere. A new study finds that these microbial communities flourish in seabed depressions ...

Confirmation of an auroral phenomenon

A new auroral phenomenon discovered by Finnish researchers a year ago is probably caused by areas of increased oxygen atom density occurring in an atmospheric wave channel. The speculative explanation offered by the researchers ...
