Genetic engineering and other advanced technologies may need to come into play if people want to live in Mars.

Last month’s NASA and SpaceX successful launch of astronauts from US soil for the first time in almost a decade, has reignited discussion about space travel to Mars and beyond. SpaceX is fronted by the billionaire Elon Musk.

A mysterious cloud containing radioactive ruthenium-106, which moved across Europe in autumn 2017, is still bothering Europe’s radiation protection entities. Although the activity concentrations were innocuous, they reached up to 100 times the levels of what had been detected over Europe in the aftermath of the Fukushima accident. Since no government had assumed responsibility, a military background could not be ruled out.

Researchers at the Leibniz University Hannover and the University of Münster (both Germany) were able to confirm that the cloud did not originate from military sources—but rather from civilian nuclear activities. Hence, the release of ruthenium from a reprocessing plant for nuclear fuels is the most conclusive scenario for explaining the incident in autumn 2017. The study has been published in the journal Nature Communications.

BioMed Realty, a real estate development firm that specializes in life-sciences and biotech space, is taking over development of a multi-acre site in Somerville’s Assembly Square to create a “best-in-class life science office park.”

BioMed has agreed to acquire an existing office at 5 Middlesex Ave. in Somerville, as well as 7.5 acres of land for future development, from a joint venture of Novaya Real Estate Ventures and Cresset Development. The firms did not disclose terms of the agreement.

BioMed, which investment giant Blackstone acquired in 2016, has a local portfolio spanning 3.5 million square feet, including a number of properties in Cambridge, as well as facilities in Watertown and Boston’s Longwood Medical Area. Its most recent project proposal in Cambridge is for a 16-story office and lab at 585 Third St.

Duke University researchers have developed an AI tool that can turn blurry, unrecognizable pictures of people’s faces into eerily convincing computer-generated portraits, in finer detail than ever before.

Previous methods can scale an image of a face up to eight times its original resolution. But the Duke team has come up with a way to take a handful of pixels and create realistic-looking faces with up to 64 times the resolution, ‘imagining’ features such as fine lines, eyelashes and stubble that weren’t there in the first place.

“Never have super-resolution images been created at this resolution before with this much detail,” said Duke computer scientist Cynthia Rudin, who led the team.

True genetic isolation is hard to pull off. Human populations tend to mix when they are in close proximity.

Consider the Hui people. These are Muslims who live across China and speak the local Chinese dialect of their locale. The Hui claim descent from Central Asians and Persians who arrived in China around 1,000 years ago. But the vast majority of their genomes are no different from the Han Chinese. Physically they are impossible to distinguish from Han Chinese unless you take note of their attire.

How can that be when they are so culturally different? For example, as Muslims the Hui do not eat pork and consider it unclean. In contrast, for the majority Han pork is dietary staple.

Analysing data from hundreds of major earthquakes, Doyeon Kim at the University of Maryland and his colleagues have found a new structure beneath the volcanic Marquesas Islands in the South Pacific Ocean. The structure, known as an ultra-low velocity (ULV) zone, is about 1000 kilometres in diameter and 25 kilometres thick, says Kim.

These structures are called ULV zones because seismic waves pass through them at slower velocities, but what they are made of is still a mystery. They might be chemically distinct from Earth’s iron–nickel alloy core and silicate rock mantle, or have different thermal properties.

The researchers discovered the structure while analysing 7000 records of seismic activity from earthquakes that occurred around the Pacific Ocean basin between 1990 and 2018. The earthquakes all had a magnitude of 6.5 or greater, and were all deeper than 200 kilometres below Earth’s surface.
