NASA lab confirms DNA sugar can be made in space, adding evidence that ‘life’ could be all over the universe
NASA researchers at the Ames’ Astrophysics and Astrochemistry Lab in Mountain View, California have provided the first experimental evidence demonstrating that the sugar in DNA – 2-deoxyribose – can be formed in interstellar space. In their study published on December 18, 2018 in the journal Nature Communications, Michel Nuevo, George Cooper, and Scott Sandford combined organic compounds, water vapor, and light – all elements present in interstellar space – inside a vacuum chamber mimicking the cosmic environment and observed the results. Along with the DNA sugar, a variety of other sugar derivatives were found to have been created. This discovery is more evidence that the chemical building blocks of life could be common all over the universe, seeding other planets as they did Earth in the ancient past.
One of the biggest questions science is constantly pursuing is whether we are alone in the universe, a research endeavor that takes many paths. Astrophysicist Carl Sagan is famously quoted often, saying, “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of star stuff.” It meant that the universe is filled with the building blocks of life, thus the pursuit to find out how those building blocks combine to actually form life is an endeavor with the farthest reaching implications. Scott Sandford, one of the study’s researchers, added to this in reference to his own team’s experiment, saying, “The universe is an organic chemist. It has big beakers and lots of time – and the result is a lot of organic material, some of which is useful to life.”
To make their discovery, the Ames team cooled an aluminum substance to near absolute zero inside a vacuum chamber (since space is a vacuum), and added a mixture of water vapor and methanol gas before exposing it to ultraviolet light and heat, fully mimicking the interstellar environment. The space between stars is filled with dust and gases and is constantly subjected to light particles bombarding in from every radiation-emitting source around it. The experiment was designed to help answer the question of whether the space environment itself can make the compounds essential to life rather than just the single-elemental building blocks. Another team of researchers in France previously discovered the creation of ribose – the sugar in RNA, a possible precursor to DNA – in an experiment similar to the current study, setting the stage for the team’s further findings.
A growing number of organic compounds have been found on meteorites over the years including carbon, hydrogen, oxygen, nitrogen, and sulphur. Despite the actively changing geography of Earth complicating the discovery of remnants from its very early days, scientists have been able to find and study things like carbonaceous chondrites, meteorites originating from asteroids as old as our solar system. This research has made it possible to analyze how planets have formed and evolved over billions of years. Combining this type of research along with other work demonstrating that meteorites in general contain the building blocks of life and travel throughout the galaxies of the universe, the expanding number of exoplanets being found could imply even more significant possibilities.
Exoplanets, i.e., planets that orbit stars other than our own, are being discovered on a regular basis as data from prior and current observatory and telescope missions is reviewed. Over the last 20 years since “planet hunting” really got started, over 3800 exoplanets have been confirmed with around 2900 more awaiting confirmation. By observing the amount of light a distant star dims over period of time, scientists can determine whether there is a planet orbiting it, its size, distance from its star, and the colors missing in the planets’ atmosphere light spectrum which tell what chemicals are present, such as oxygen, carbon dioxide, nitrogen, and so forth. After analyzing all of these things, it can be predicted whether an exoplanet may be Earth-like and whether it’s in what’s called the “Goldilocks Zone”, or position where life as we know it might have the right conditions to evolve.
That may seem like a lot of conditions to meet, but it’s estimated that around 20-50 percent of the stars in our night sky may have small, rocky planets in their stars’ habitable zones. As more is learned about planet formation, that number may be revised up or down. Thus far, one planetary system has been studied extensively that has planets somewhat similar to Earth: TRAPPIST-1. It’s comprised of an ultra-cool dwarf star with 7 rocky worlds orbiting it, all of them potentially having water, some more than Earth. Considering the growing evidence that the seeds for life to evolve are prominently distributed and created throughout space with the number of potentially Earth-like planets being discovered, we may have some exciting news from the interstellar world in the near future.

Tesla starts laying the groundwork for FSD tests in Austria
The job opening comes as the company pushes regulatory approvals and data collection in new European markets.
Tesla seems to be ramping its efforts to hire key personnel for FSD’s eventual expansion in Europe. This was hinted at in a new job listing for a vehicle operator role in Vienna, Austria.
The job opening comes as the company pushes regulatory approvals and data collection in new European markets.
Vienna’s vehicle operator role
Tesla posted the job for “Fahrer (Vehicle Operator) (m/w/d)” in its Vienna office on its Careers website, seeking candidates to drive and monitor test vehicles as part of the Autopilot and AI team. The role involves collecting real-world driving data to refine Full Self-Driving systems for the country’s local roads. Responsibilities include operating vehicles in urban and highway environments, documenting system performance, among other tasks.
Applicants need a valid Austrian driver’s license and at least two years of driving experience. Fluency in English is essential, along with a familiarity with driver assist systems. Tesla noted that the position offers a minimum annual gross salary of EUR 32,000, though relevant professional experience and qualifications will be taken into account. Similar to other Tesla roles, the position also offers TSLA stock as an incentive.
Tesla’s FSD Push in Europe
Tesla’s FSD efforts in Europe have accelerated in recent months, with significant progress in Spain serving as a key milestone. In July 2025, Spain’s Directorate-General for Traffic launched the ES-AV framework to standardize automated vehicle testing, authorizing Tesla for nationwide FSD trials with 19 vehicles under Phase 3, which allows optional onboard safety operators and remote monitoring.
-->The program, running through November 2027, aims to position Spain as a leader in the field, as DGT stated: “The program is designed to complement and enhance oversight, regulation, research, and transparency efforts, as well as to support innovation and advancements in automotive technology and industry.”
Beyond Spain, Tesla has conducted FSD demonstrations in Germany, France and Italy for consumers, while pursuing national approval in the Netherlands for early 2026.

Tesla Semi factory looks almost complete during Thanksgiving weekend
Based on recent drone videos, the Tesla Semi factory looks practically ready to start operations.
It appears that the Tesla Semi factory near Giga Nevada is already hard at work preparing for the initial production of the Class 8 all-electric truck. This was, at least, hinted at in a recent drone flyover of the facility from a longtime watcher.
The Tesla Semi factory after Thanksgiving
Drone operator and Tesla Semi advocate @HinrichsZane recently shared some footage he captured of the upcoming facility during the Thanksgiving weekend. Based on his video, it appears that Tesla gave its employees in the area the weekend off. One thing is evident from the video, however, and that is the fact that the Tesla Semi factory looks practically ready to start operations.
The Tesla Semi watcher did point out that the electric vehicle maker is still busy bringing in production equipment into the facility itself. Once these are installed, it would not be surprising if initial production of the Tesla Semi begins.
A new Tesla Semi
The upcoming completion of the Tesla Semi factory near Gigafactory Nevada seems all but inevitable in the coming months. What would be especially interesting, however, would be the vehicles that would be produced on the site. During Elon Musk’s presentation at the 2025 Annual Shareholder Meeting, a glimpse of the production Tesla Semi was shown, and it looks quite a bit different than the Class 8 all-electric truck’s classic appearance.
As could be seen in the graphic from the CEO’s presentation, the updated Tesla Semi will feature slim lightbar headlights similar to the new Tesla Model Y, Cybertruck, and the Cybercab. Tesla also teased a number of aerodynamic improvements that increased the truck’s efficiency to 1.7 kWh per mile. Extended camera units, seemingly for FSD, could also be seen in the graphic.
