The global food system could drive rapid and widespread biodiversity loss if not changed, new research has found. The findings show that the world’s food system will need to be transformed to prevent habitat loss across the globe. The international research team found that what we eat and how it is produced will need to change rapidly and dramatically to prevent widespread and severe biodiversity losses.

The threshold for dangerous global warming will likely be crossed between 2027 and 2042 – a much narrower window than the Intergovernmental Panel on Climate Change’s estimate of between now and 2052. In a study, researchers introduce a new and more precise way to project the Earth’s temperature. Based on historical data, it considerably reduces uncertainties compared to previous approaches.

Although violent and unpredictable, stellar flares emitted by a planet’s host star do not necessarily prevent life from forming, according to a new study. By combining 3D atmospheric chemistry and climate modeling with observed flare data from distant stars, a team discovered that stellar flares could play an important role in the long-term evolution of a planet’s atmosphere and habitability.

It took fifteen years of imaging and nearly three years of stitching the pieces together to create the largest image ever made, the 8-trillion-pixel mosaic of Mars’ surface. Now, the first study to utilize the image in its entirety provides unprecedented insight into the ancient river systems that once covered the expansive plains in the planet’s southern hemisphere. These three billion-year-old sedimentary rocks, like those in Earth’s geologic record, could prove valuable targets for future exploration of past climates and tectonics on Mars.

The perfect transmission of sound through a barrier is difficult to achieve, if not impossible based on our existing knowledge. This is also true with other energy forms such as light and heat. A research team has for the first time experimentally proved a century old quantum theory that relativistic particles can pass through a barrier with 100% transmission.

While global sea levels are rising due to the climate crisis and threatening near-coastal infrastructures, higher temperatures in other areas are having exactly the opposite effect. The water levels are falling and also causing massive problems. Although the consequences are equally serious, however, declining water levels are receiving less attention according to a new study.
