On 22 December 2018, a flank of the Anak Krakatau plunged into the Sunda strait between the Indonesian islands of Sumatra and Java, triggering a tsunami that killed 430 people. An international research team has now shown that the volcano produced clear warning signals before its collapse. The researchers recommend to use their study to improve monitoring of volcanoes.
Read moreFaced with extreme weather events and unprecedented environmental change, animals and plants are scrambling to catch up — with mixed results. A new model helps to predict the types of changes that could drive a given species to extinction.
Read moreRising ocean temperatures have long been linked to negative impacts for marine life, but a team has recently found that the long-term outlook for many marine species is much more complex — and possibly bleaker — than scientists previously believed.
Read moreMany scientists have said that storms are more intense than ever before – Cat. 4 or 5 storms used to be outliers, but today, it seems they are becoming the norm. Why? That's the question a research team is working to answer – they are looking what contributes to the rapid intensification of storms.
Read moreResearchers have developed a new laser-based system that offers an efficient and low-cost way to detect fires in challenging environments such as industrial facilities or large construction sites. With further development, the system could eventually detect fires that are more than a kilometer away.
Read moreOverturning tractors are the leading cause of death for farmers around the world. In order to reduce the rate of overturned tractors, researchers have developed a model for understanding the conditions that lead to a tractor overturning from an unlikely source: They based their model on one used to understand the unpredictability of a bouncing ball.

Read moreThe wind is always blowing somewhere, but deciding where to locate a wind farm is a bit more complicated than holding up a wet finger. Now a team of researchers has a model that can locate the best place for the wind farm and even help with 24-hour predictions of energy output.
Read moreBeing able to accurately forecast how much solar energy reaches the surface of the Earth is key to guiding decisions for running solar power plants and new work looks to provide a standard of reference to the field. A researcher proposes an improved way to assess day-ahead solar forecasting, which combines two popular reference methods for weather forecasting, namely persistence and climatology. His approach provides a new way to gauge the skill of a forecaster.
Read moreFor more than a century, a guiding principle in seismology has been that earthquakes recur at semi-regular intervals according to a 'seismic cycle.' In this model, strain that gradually accumulates along a locked fault is completely released in a large earthquake. Recently, however, seismologists have realized that earthquakes often occur in clusters separated by gaps, and one research group now argues that the probability of a tremor's recurrence depends upon whether a cluster is ongoing — or over.
