A new study found that 50 minutes of dry heat in an electric cooker decontaminated N95 respirators inside and out while maintaining their filtration and fit. This could enable wearers to safely reuse limited supplies of the respirators.

Nearly 10 years after the Tohoku-oki earthquake and tsunami devastated Japan's Fukushima Dai-ichi Nuclear Power, radiation levels have fallen to safe levels in all but the waters closest to the shuttered power plant. A new article looks at the many radioactive elements contained in the tanks and suggests that more needs to be done to understand the potential risks of releasing wastewater from the tanks into the ocean.

Engineers have studied the simple act of shaving up close, observing how a razor blade can be damaged as it cuts human hair -- a material that is 50 times softer than the blade itself. They found that hair shaving deforms a blade in a way that is more complex than simply wearing down the edge over time.

Taking advantage of a total lunar eclipse, Hubble used the Moon as a mirror to study sunlight that had passed through Earth's atmosphere. As a result, Hubble detected Earth's own brand of sunscreen - ozone - in our atmosphere. The technique simulates how scientists will search for evidence of life on planets around other stars.

The periodic system contains 118 chemical elements. However, only a few of them are of major importance in our daily lives. An international research group has now discovered astonishing and beautiful molecular structures when they used the element tellurium in ring-shaped hydrocarbon molecules. These compounds are distinguished by the fact that they are arranged in the crystal to form highly symmetrical tubes that interact with each other via the tellurium atoms.
