Fungal infections are killing thousands of Americans each year, some with a morbidity rate of nearly 80%. To make matters worse, only a handful of antifungal treatments are available, and even those are becoming less effective as fungi become more resistant. However, researchers recently published findings indicating that a novel breakthrough treatment may have been discovered.

Geoscientists have long thought that water -- along with shallow magma stored in Earth's crust -- drives volcanoes to erupt. Now, thanks to newly developed research tools, scientists have learned that gaseous carbon dioxide can trigger explosive eruptions.

Kama?ehuakanaloa (formerly L??ihi Seamount), a submarine Hawaiian volcano located about 20 miles off the south coast of the Big Island of Hawai'i, has erupted at least five times in the last 150 years, according to new research led by Earth scientists at the University of Hawai'i at M?noa.

Researchers have optimized a new technique to help forecast how volcanoes will behave, which could save lives and property around the world.

Scientists have wondered what happens to the organic and inorganic carbon that Earth's Pacific Plate carries with it as it slides into the planet's interior along the volcano-studded Ring of Fire. A new study suggests a notable amount of such subducted carbon returns to the atmosphere rather than traveling deep into Earth's mantle.

Volcanic disasters have been studied since Pompeii was buried in 79 A.D., leading the public to believe that scientists already know why, where, when and how long volcanoes will erupt. But a volcanologist said these fundamental questions remain a mystery.

Scientists have discovered a new molecular signalling pathway, triggered when leaves are exposed to low humidity, that ensures plant roots keep growing towards water. A new study has found that when the leaves of a plant are exposed to dry air (low humidity), they send a shoot-to-root signal, using abscisic acid (ABA), to tell the roots to keep growing. This is a surprising finding as ABA is usually thought to be a growth inhibitor, not a growth promoter.

Researchers have found that the cooling effect that volcanic eruptions have on Earth's surface temperature is likely underestimated by a factor of two, and potentially as much as a factor of four, in standard climate projections.

An obscure aquatic plant has helped to explain how plants avoid cracking up under the stresses and strains of growth.

For the first time, researchers have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's physiological traits. Their work reveals unprecedented insights into gene regulatory networks and identifies a new library of DNA parts that can be used to optimize plants for bioenergy and agriculture.

As scientists try to understand the effect of climate on trees, advances in imaging technology are helping them see both the whole forest and every individual tree. High-resolution images taken by cubesats, small, shoebox-sized devices launched into low Earth orbit, are helping environmental scientists make more precise measurements about trees' response to a warming climate.

Researchers have discovered that extracts from plants used by the Kwakwaka'wakw First Nations peoples in their traditional botanical medicine practices are able to rescue the function of ion channel proteins carrying mutations that cause human Episodic Ataxia.

Machine learning can help extract important information from the huge numbers of plant specimens stored in herbaria, say scientists.

New research showed that the plume emitted by the Hunga Volcano eruption in 2022 created the highest lightning flash rates ever recorded on Earth, more than any storm ever documented.

Biologists provide evidence for an alternative genetic mechanism that can lead to plants becoming self-pollinators.

A 3D model of a 407-million-year-old plant fossil has overturned thinking on the evolution of leaves. The research has also led to fresh insights about spectacular patterns found in plants.

New work deploys a bold new approach for inferring the temperature sensitivity of ecosystem respiration -- which represents one side of the equation balancing carbon dioxide uptake and carbon dioxide output in terrestrial environments. This will improve scientists' models for climate change scenarios.

A cutting-edge experiment has revealed the quantum dynamics of one of nature's most crucial processes.

The new study used a model of volcano fracturing to interpret patterns of earthquakes and ground uplift, and concluded that parts of the volcano had been stretched nearly to breaking point.
