Debugging Behind the Iron Curtain (2010)

Sergei is a veteran of the early days of the computing industry as it was developing in the Soviet Union. I had the pleasure of working and learning from him over the past year, and in that time I picked up more important lessons about both life and embedded programming than any amount of school could ever teach. The most striking lesson is the story of how and why, in late summer of 1986, Sergei decided to move his family out of the Soviet Union. In the 1980s, my mentor Sergei was writing soft

LHC's New Chip Tackles Radiation Challenges

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. Deep in the belly of the Large Hadron Collider (LHC), about 400 million particle collisions are happening in a single second. But as the LHC undergoes upgrades and becomes the High Luminosity-LHC, the number of collisions will increase to an astounding ~1.5 billion collisions or more per second. Capturing all these events via detectors and analyzing the staggering amount of data created from each ex

Synthetic Biology for Space Exploration

The Apollo 11 Moon landing encouraged humankind to consider and investigate life beyond Earth more than 50 years ago1. However, in contrast to its lightning-fast success in terms of the remarkable technology development of the Mercury, Gemini and Apollo programs, human space exploration has been confined in Low Earth Orbit (LEO) for the past 50 years. Nevertheless, other space agencies, such as the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA), have joined the two

The ‘Hail Mary’ That Saved NASA’s Juno Camera From Jupiter’s Radiation Hell

NASA’s Juno spacecraft, which launched in 2011 to investigate Jupiter’s origin and evolution, travels through the solar system’s most intense planetary radiation fields. When the spacecraft’s JunoCam—a color, visible-light camera—began to suffer the consequences in December 2023, the mission team back on Earth had to think of a remote fix before they lost their chance to photograph the Jovian moon, Io. A relatively simple process was ultimately what enabled the long-distance save: heating the i

Scientists Are Sending Cannabis Seeds to Space

Having dedicated much of his working life to studying the cannabis plant, Radišič believes it is uniquely qualified for space agriculture. It grows fast, adapts well, and has been an agricultural crop for thousands of years. According to Radišič, if at some point we want to grow life on Mars, this makes it an ideal candidate. “Sooner or later, we will have lunar bases, and cannabis, with its versatility, is the ideal plant to supply those projects,” he tells WIRED. “It can be a source of food, p

Preparation of a neutral nitrogen allotrope hexanitrogen C2h-N6

As AgN 3 is an excellent reagent for the synthesis of polyazides35 and halogen azides both in the gas phase36 and in solution37,38, we suggest that the reaction of AgN 3 with XN 3 (X = halogen) is a viable route to N 6 (Fig. 1b). The reactions were conducted in either a quartz tube or a U-trap by flowing gaseous Cl 2 through solid AgN 3 under reduced pressure at room temperature (see the ‘Synthesis details’ section in Methods and Supplementary Fig. 1). Apart from the known bands of ClN 3 (ref. 3
