Enviro+ for Raspberry Pi

By Pimoroni: Monitor your world with Enviro+ for Raspberry Pi! There’s a whole bunch of fancy environmental sensors on this board, and a gorgeous little full-colour LCD to display your data. It’s the perfect way to get started with citizen science!

 

Enviro+ is an affordable alternative to environmental monitoring stations that can cost tens of thousands of pounds and, best of all, it’s small and hackable and lets you contribute your data to citizen science efforts to monitor air quality via projects like Luftdaten.

The new Enviro+ environmental monitoring sensors for Raspberry Pi

The alarming drop in our air quality is something that’s really important to understand. Devices like Enviro+ allow fine-grained, detailed datasets that let us see shifts in air quality through time and across different areas of cities. The more devices that contribute data, the better quality the dataset becomes.

Three reasons why the periodic table needs a redesign

New Scientist: Chemists can’t agree on the best way to arrange the elements, prompting proposals of everything from spiral-shaped alternatives to radically elongated versions.

Theodor Benfey periodic table

Above: This reimagining of the periodic table, proposed by chemist Theodor Benfey in 1964, emphasises the continuity of the elements rather than imposing artificial breaks.

Mark Leach at Manchester Metropolitan University, UK, keeps the internet database of periodic tables, which contains hundreds of versions.

Why the periodic table needs a redesign

Redesigning the periodic table might seem a quixotic quest, but it could soon take on a new urgency. We are already on the trail of element 119. Where it will go, and how the table will morph to make space for it, remains to be seen.

Look at These Incredibly Realistic Faces Generated By A Neural Network

NVIDIA AI faces

Futurism: The results are spectacular. Even small seemingly random details like freckles, skin pores or stubble are convincingly distributed in the images the project generated.

Incredibly realistic faces generated by a neural network

“Researchers at NVIDIA have harnessed the power of a generative adversarial network (GAN) — a class of neural network — to generate some extremely realistic faces. The results are more impressive than anything we’ve seen before.” — Futurism

Researchers map where subjective feelings are located in the body

Bodily feeling maps
Pixel intensities show regions where each feeling was associated with statistically significant bodily sensations.

British Psychological Society: “How do you feel?” is a simple and commonly asked question that belies the complex nature of our conscious experiences. The feelings and emotions we experience daily consist of bodily sensations, often accompanied by some kind of thought process, yet we still know very little about exactly how these different aspects relate to one another, or about how such experiences are organised in the brain.

Now, reporting their results in PNAS, a team of researchers in Finland, led by neuroscientist Lauri Nummenmaa of the University of Turku, has produced detailed maps of what they call the “human feeling space”, showing how each of dozens of these subjective feelings is associated with a unique set of bodily sensations. [⋮]

The new results provide yet more evidence for the emerging idea that the body plays a crucial role in cognitive and emotional processes – something which has, until very recently, been overlooked. “In other words,” says study co-author Riita Hari, “the human mind is strongly embodied.”

The Dark Past of Sea Monkeys

Great Big Story: This is the story of how a tiny, magical creature was transformed into a cultural phenomenon by inventor, marketing genius and complicated eccentric Harold von Braunhut. Full of fun facts (both charming and disturbing), Just Add Water is a colorful short film about a half-century of marketing directly to children, the force of nostalgia in pop culture, and an unlikely meeting of flim-flam and hard science. A film by Penny Lane.

Antineutrino Global Map 2015

The open source AGM2015 provides fundamental data for experiments, assists in strategic detector placement to determine neutrino mass hierarchy, and aids in identifying undeclared nuclear reactors.

Antineutrino Global Map 2015

“The open access availability of these antineutrino maps represents the next generation of cartography and gives important insights into the basic understanding about the interior of our planet.” Shawn Usman — NGA R&D

This is what Earth would look like if you could see its glow of neutrinos–from natural radioactivity mostly, but lightly dotted with nuclear reactors. Amazing map. [⋮] Continental rocks are enriched in uranium and thorium, so the continents “glow” in antineutrinos.” — @coreyspowell

Juno Perijove — Jupiter Flyby

A wonderful video by Seán Doran putting recent imagery from the Juno spacecraft to György Ligeti’s Atmosphères, famously used in 2001: A Space Odyssey.

From the original video: This computer animation uses the JunoCam images of PJ-05 as textures, and SPICE trajectory data in order to reconstruct the flyby as seen from Juno’s perspective.

Above: Edits by Seán Doran // Below: as featured on APOD

On May 19, the Juno spacecraft once again swung by Jupiter in its looping 53 day orbit around the Solar System’s ruling gas giant.

Perijove Passage

APOD: Beginning at the top, this vertical 14 frame sequence of enhanced-color JunoCam images follows the spacecraft’s rapidly changing perspective during its two hour passage. They look down on Jupiter’s north polar region, equatorial, and south polar region (bottom images). With the field-of-view shrinking, the seventh and eighth images in the sequence are close-up. Taken only 4 minutes apart above Jupiter’s equator they were captured just before the spacecraft reached perijove 6, its closest approach to Jupiter on this orbit. Final images in the sequence pick up white oval storm systems, Jupiter’s “String of Pearls”, and the south polar region from the outward bound spacecraft.
