New research links chemical changes in seawater to volcanic activity, climate — ScienceDaily

Sea salt hides a secret: tiny droplets of the seawater from which it came, preserving geologic history. Using specializing equipment obtained from National Science Foundation grant funds, Mebrahtu Weldeghebriel, PhD ’22, a postdoctoral fellow at Princeton University, and Binghamton University Distinguished Professor of Earth Sciences Tim Lowenstein were able to reconstruct changes in seawater chemistry … Read more

Particulate air pollution a growing risk for premature CVD death and disability worldwide — ScienceDaily

The impact of particulate matter air pollution on death and disability is on the rise worldwide, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association. Previous research established the association of particulate matter (PM) pollution to CVD death and disability. … Read more

Microplastics found in human heart tissues, both before and after surgical procedures — ScienceDaily

Everywhere scientists look for microplastics, they’ve found them — food, water, air and some parts of the human body. But examinations of our innermost organs that aren’t directly exposed to the environment are still limited. Now, in a pilot study of people who underwent heart surgery, researchers in ACS’ Environmental Science & Technology report that … Read more

Land-sea relationship is major driver of coral reef health outcomes — ScienceDaily

Climate change has long been considered as one of the greatest drivers of declining coral reefs, but the specifics of human impact have been largely unverified. In a new paper published in Nature, researchers tracked coral reef health in Hawai’i for 20 years — measuring increasing water acidification, land-based pollution, repercussions from a major climate … Read more

Did the Horn of Africa reach a drought tipping point 11,700 years ago? — ScienceDaily

New research suggests that the Horn of Africa is likely to become even drier, not wetter in the future as predicted by most climate models. ‘Wet gets wetter, dry gets drier’. That mantra has been used for decennia to predict how global warming will affect the hydrological cycle in different world regions. But if climate … Read more

Research identifies patterns to predict co-occurrence of heat and ozone extremes in China months — ScienceDaily

High temperatures exacerbate ground-level ozone production, resulting in a deadly combination of extreme heat and poor air quality that is especially dangerous for children, seniors, and people suffering from preexisting respiratory illnesses. Like most of the globe, China is dealing with increasing temperatures and longer and more frequent heat waves. But, because of its rapid, … Read more
