The eruption in the South Pacific earlier this year released what was likely the most powerful explosion the world has experienced since the famous 1883 eruption of Mt. Krakatau in Indonesia. The rapid release of energy excited pressure waves in the atmosphere that quickly spread around the world. The atmospheric wave pattern close to the …

Michalski and the international team recently published their results in Nature Astronomy, which describe a global analysis of ancient Martian lakes. “We know of approximately 500 ancient lakes deposited on Mars, but nearly all the lakes we know about are larger than 100 km2,” explains Michalski. “But on Earth, 70% of the lakes are smaller …
While the negative cardiovascular effects of air pollution on adults has already been established, this study is the first to assess the impact of air pollution on teenagers in the general population. “While relatively rare, irregular heart rhythms can lead to sudden cardiac death in otherwise healthy adolescents and young adults. Our findings linking air …

The results of an extensive five-year study conducted in Peru revealed a 50% decline in arthropod biomass following short periods of both drought and increased precipitation. One of only a few studies of this scope conducted in the tropics, the findings suggest terrestrial arthropods, a group that includes insects and spiders, will be more susceptible …

The concern about plastic pollution has become widespread after it was realised that mismanaged plastics in the environment break down into smaller pieces known as microplastics and nanoplastics. It is likely that nanoplastics, due to their small size, can pass through physiological barriers and enter organisms. Despite the growing body of evidence on the potential …
Nanoplastics can move up the food chain from plants to insects and from insects to fish Read More »
An international research team synthesised evidence for tipping points, their temperature thresholds, timescales, and impacts from a comprehensive review of over 200 papers published since 2008, when climate tipping points were first rigorously defined. They have increased the list of potential tipping points from nine to sixteen. The research, published in advance of a major …

Heat waves, drought, floods, forest fires — the consequences of climate change are increasing and are changing our environment. A prime example is the countryside in the catchment area for the Rappbode reservoir in the eastern Harz region. This is the largest drinking water reservoir in Germany and provides drinking water for roughly one million …

A new study published today in leading journal, Science, finds that between 90 and 99 percent of all deforestation in the tropics is driven directly or indirectly by agriculture. Yet only half to two-thirds of this results in the expansion of active agricultural production on the deforested land. The study is a collaboration between many …

In a new study, Yale University researchers discovered that light is a surprising ally in fostering this electronic activity within biofilm bacteria. Exposing bacteria-produced nanowires to light, they found, yielded an up to a 100-fold increase in electrical conductivity. The findings were published Sept. 7 in the journal Nature Communications, “The dramatic current increases in …

The work was done in collaboration with scientists from the University of Toledo, the University of Colorado-Boulder, and the University of California-San Diego. A unique architectural structure enabled the researchers to record a certified stabilized efficiency of 24% under 1-sun illumination, making it the highest reported of its kind. The highly efficient cell also retained …
