The Eastern Pacific Ocean's Tropical Depression 9E formed on July 26 and by July 27 the depression had dissipated over 1,200 miles from Hilo, Hawaii. NASA's Terra satellite captured a look at the storm at its peak.

Washington State University researchers have created a sustainable alternative to traditional concrete using coal fly ash, a waste product of coal-based electricity generation.

The advance tackles two major environmental problems at once by making use of coal production waste and by significantly reducing the environmental impact of concrete production.

Xianming Shi, associate professor in WSU’s Department of Civil and Environmental Engineering, and graduate student Gang Xu, have developed a strong, durable concrete that uses fly ash as a binder and eliminates the use of environmentally intensive cement. They report on their work in the August issue of the journal, Fuel.

Renewable energy met more of Germany’s electricity needs than coal during the first six months of 2018 — the longest period that renewables have been the country’s largest source of energy to date. According to new data from the German Association of Energy and Water Industries (BDEW), 36.3 percent of Germany’s electricity was generated by solar, wind, hydropower, and biogas between January and June of this year, while coal provided only 35.1 percent.

The second tropical cyclone of the North Atlantic Hurricane season formed in the Central Atlantic Ocean and far from land. NASA's Terra satellite provided an early morning look at the small depression.

Scientists have developed a technique that allows them to measure how well cancer drugs reach their targets inside the body. It shows individual cancer cells in a tumour in real time, revealing which cells interact with the drug and which cells the drug fails to reach.

In the future, the findings, published in Nature Communications, could help clinicians decide the best course and delivery of treatment for cancer patients.
