A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.

Researchers have discovered 16 new species of strange-looking parasitoid wasps from the Loboscelidia group. The study also revealed for the first time the unique parasitic behavior of a captive female from one species, who after parasitizing her host egg, buried the egg in a hole in the soil.

A new type of analysis suggests that droughts in Ohio were more severe from 2000 to 2019 than standard measurements have suggested.

Fires that raged in the days following the 1 September 1923 magnitude 7.9 Kant earthquake killed roughly 90% of the 105,000 people who perished in and around Tokyo, making it one of the deadliest natural disasters in history -- comparable to the number of people killed in the World War II atomic bombing of Hiroshima. The story of the conflagration, not well-known outside of Japan, holds important lessons for earthquake scientists, emergency response teams and city planners, according to a new article.

Researchers have developed a new simulation model, which can predict flooding during an ongoing disaster more quickly and accurately than currently possible.

A review of almost 1000 studies on the effects of climate change and extreme weather events on rivers around the world has found an overall negative effect on water quality in rivers globally. An international team of experts sourced from every continent, conducted between 2000-2022.

Climate experts project a decline in the frequency of future tropical storms but an increase in their strength across the Ganges and Mekong basins allowing for better future planning.

Research found that, in some western states, the amount of snow already on the ground by the end of December is a good predictor of how much total snow that area will get.

Researchers have focused on the moisture present in the air as a potential source of drinking water for drought-stressed populations. They reached a significant breakthrough in their efforts to create drinkable water out of thin air: a molecularly engineered hydrogel that can create clean water using just the energy from sunlight.

Failing to achieve climate mitigation goals puts increasing pressure on climate adaptation strategies. In two new studies, researchers address novel approaches to these issues.

The sun and the sea -- both abundant and free -- are being harnessed in a unique project to create vertical sea farms floating on the ocean that can produce fresh water for drinking and agriculture.

Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.

Atmospheric scientists have discovered abundant fine sea salt aerosol production from wind-blown snow in the central Arctic, increasing seasonal surface warming.

Tropical forests in South America lose their ability to absorb carbon from the atmosphere when conditions become exceptionally hot and dry, according to new research. For a long time, tropical forests have acted as a carbon sink, taking more carbon out of the air than they release into it, a process that has moderated the impact of climate change. But new research found that in 2015 -- 2016, when an El Niño climate event resulted in drought and the hottest temperatures ever recorded, South American forests were unable to function as a carbon sink.

At a time of unparalleled rates of biodiversity loss, a new interconnected system to monitor biodiversity around the world is needed to guide action quickly enough to target conservation efforts to where they are most needed.

As climate change continues to pose severe challenges to ensuring sustainable food supplies around the world, scientists are looking for ways to improve the resilience and nutritional quality of potatoes. Scientists have assembled the genome sequences of nearly 300 varieties of potatoes and its wild relatives to develop more nutritious, disease-free, and weather-proof crop. A team has now created a potato super pangenome to identify genetic traits that can help produce the next super spud.
