In the months after, the agency measured whether the thermal protection system effectively safeguarded the crew and Orion systems as the spacecraft reentered Earth’s atmosphere. This rigorous analysis confirmed that the […]

A deep-sea microbe uses an exceptionally heat-resistant enzyme to turn atmospheric nitrogen into ammonia at temperatures that would destroy most proteins. Its unusual structure and a newly observed reaction state may reveal an ancient, shared mechanism behind nitrogen fixation and could eventually inspire cleaner biotechnology and fertilizer production.

Low-e windows keep homes cool … but may set neighbours’ property on fire

Low-emissivity windows also keep houses warm in winter, but use on bowed glass can have magnifying-glass effect Low-emissivity or low-E window glass is a useful green technology for keeping buildings warm in winter and cool in summer … but a rare side-effect can set the neighbours’ property on fire. The glass is coated with a thin layer of metal or metal oxide which lets visible light through but acts like a mirror in the infrared. Heat from the interior is reflected back in, retaining warmth in winter, while unwanted solar radiation is repelled in summer. Continue reading...
