First discovered in Italy's Ötztal Alps in September 1991, Ötzi was a prehistoric man who died, likely by murder, some 5,300 years ago before being mummified naturally inside glacier ice. But bad news for Ötzi was good news for four strains of cold-adapted glacier yeasts, which infiltrated his body shortly after his death and may still be active today. In fact, some of these yeasts are just right for baking bread — the scientists used it to make a sourdough they described as "very very good."

When is a tech company conspiring to release 64 million bacteria-riddled mosquitoes across the U.S. good news? This week, it turns out, with an application made by Google to the Environmental Protection Agency (EPA) for an experimental mosquito release permit.
The mosquitoes in question are non-biting male southern house mosquitoes (Culex quinquefasciatus) — a species whose females transmit diseases like West Nile virus and St. Louis encephalitis in humans. Infected with a bacterium called Wolbachia pipientis, the released males will prevent any females they mate with from having offspring, thereby slashing mosquito populations and disease rates over time.
The EPA has deemed Google's request to be of potential regional and national significance. The agency will make a final decision whether to grant the permit following a public comment period that ended on June 5.

Of the four fundamental forces, gravity is the one we experience most immediately throughout our lives. Yet it also remains the most mysterious — being a major confounding factor for any successful theory of everything. In fact, we can't even figure out exactly how strong Earth's gravity is. But why is it so hard to measure?

NASA announced a final farewell for its Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft this week — the probe is officially dead after 11 years of studying the Red Planet from orbit.
NASA lost contact with the probe in December of last year when it swung behind Mars on a regular orbit, only to go dark at the time of its reemergence. After convening a review board in February, the agency has now shared its findings that the craft appears to be dead for good. The culprit remains, thus far, a mystery; but a fragment of telemetry data hints that the spacecraft's unusually rapid rotation depleted its battery power.

When is a dead volcano just taking a nap? The disquieting answer may be more often than we thought, following the discovery by volcanologists that the extinct volcanoes surrounding us might actually just be going through a growth period before they roar back to life.
That's according to a new analysis of the formerly-extinct volcano Methana, near Athens, Greece, which has been found to have slept for 110,000 years before returning to activity. To figure out what this means for the other sleeping giants that surround us, Live Science contributor Chris Simms investigated.

An almighty roar and a vapor trail was about as much advance warning as the world got ahead of the maiden launch of China's Long March 12B rocket, which reportedly took off without any advance airspace notices on Monday (June 1).
The rocket is China's rival to SpaceX's Falcon 9 — a reusable, commercially-ran rocket that will be used to cost-effectively launch China's megaconstellation satellites into low Earth orbit.
The surprise launch came as China ramps up its rocket launches as part of a new space race with the U.S. But if you're able to tune out all the geopolitical posturing, the flight sure made for some cool photos.
