Soap Bubble Structures by Kym Cox. Bubbles optimise space and minimise their surface area for a given volume of air. This phenomenon makes them a useful tool in many areas of research, in particular, materials science and “packing” – how things fit together. Bubble walls drain under gravity, thin at the top, thick at the bottom, which interferes with travelling lightwaves to create bands of colour. Black spots show the wall is too thin for interference colours, indicating the bubble is about to burst. (Photo by Kym Cox/2019 Science Photographer of the Year/RPS)

“The most serious health problem in the U.S. today is obesity.” Sounds familiar, doesn’t it? But that pronouncement about obesity’s primacy in the hierarchy of national health problems is not new. Rather, it’s the opening line to a remarkable article published 60 years ago in LIFE magazine. This photographs made by Martha Holmes to illustrate that March 1954 article, titled “The Plague of Overweight.” Photo: Dorothy Bradley (left), photographed for LIFE magazine article on obesity, 1949.

Woolland Woods, Dorset. Landscape photographer of the year 2020. “Taken in spring of 2018 in a wooded area close to Milborne St Andrew in Dorset, this was the third visit to the area in a matter of days. On the previous days, both devoid of morning mists, the light had been harsh and unappealing but the third day delivered stunning conditions with mist swirling through the trees. The low shooting position allowed more emphasis to be placed on the wild garlic and pathway”. (Photo by Chris Frost/UK Landscape Photographer of the Year 2020)

The NASA Extreme Environment Mission Operations (NEEMO) 21 mission began on July 21 as an international crew of aquanauts splashed down to the undersea Aquarius Reef Base, located 62 feet below the surface of the Atlantic Ocean in the Florida Keys National Marine Sanctuary. The NEEMO 21 crew will perform research both inside and outside the habitat during a 16-day simulated space mission. During simulated spacewalks carried out underwater, they will evaluate tools and mission operation techniques that could be used in future space missions, including journeys to Mars.
