Immense northern storms on Saturn can disturb atmospheric patterns at the planet's equator, finds the international Cassini mission in a study led by Dr Leigh Fletcher from the University of Leicester. This effect is also seen in Earth's atmosphere, suggesting the two planets are more alike than previously thought.

Despite their considerable differences, the atmospheres of Earth, Jupiter, and Saturn all display a remarkably similar phenomenon in their equatorial regions: vertical, cyclical, downwards-moving patterns of alternating temperatures and wind systems that repeat over a period of multiple years.

These patterns—known as the Quasi-Periodic Oscillation (QPO) on Saturn and the Quasi-Quadrennial Oscillation (QQO) on Jupiter, due to their similarities to Earth's so-called Quasi-Biennial Oscillation (QBO)—appear to be a defining characteristic of the middle layers of a planetary atmosphere.

Earth's QBO is regular and predictable, repeating every 28 months on average. However, it can be disrupted by events occurring at great distances from the equator of our planet—and a new study reveals that the same is true of Saturn's QPO.

"These oscillations can be thought of as a planet's heartbeat," says Leigh Fletcher of the University of Leicester, UK, lead author of the study (published in Nature Astronomy) and co-investigator of Cassini's Composite Infrared Spectrometer (CIRS). "Cassini spotted them on Saturn about a decade ago, and Earth-based observations have seen them on Jupiter, too. Although the atmospheres of the distant gas giants may appear startlingly different to our own, when we look closely we start to discover these familiar natural patterns."

Cassini observed Saturn from June 2004 until 15 September 2017 when the mission concluded by plunging into the gas planet's atmosphere. To better understand Saturn's QPO, Fletcher and colleagues studied data from Cassini's CIRS covering this entire time period.

"We looked at data of Saturn's 'heartbeat', which repeats roughly every 15 Earth years, and found a huge disturbance—a palpitation, to continue the metaphor—spanning 2011 to 2013, where the whole equatorial region cooled dramatically," adds co-author Sandrine Guerlet from Laboratoire de Météorologie Dynamique (LMD), France. "When we checked the timing, we realised this happened directly after the eruption of a giant storm that wrapped around Saturn's entire northern hemisphere. This suggests a link between the two events: we think that the wave activity associated with this huge storm headed towards the equator and disrupted the QPO, despite the storm raging tens of thousands of kilometres away!"

This storm was known as the Great Northern Storm. Such storms occur roughly once every Saturnian year, which is equivalent to 30 Earth years. The timing of the storm was thus serendipitous, allowing Cassini to observe it in detail from orbit around the ringed planet.

Although the influence of Saturnian storms was known to be substantial, this study suggests an even wider influence than expected, and confirms a connection between Saturn's QPO and remote, distinct events occurring elsewhere in the planet's atmosphere.

"We became especially excited when we compared this palpitation on Saturn to one observed in Earth's QBO in 2016: it was disturbed in a similar way by waves carrying momentum from Earth's northern hemisphere to the equator," adds Fletcher. "That disruption was unprecedented in over 60 years of monitoring the QBO—and yet we were lucky enough to capture a similar behaviour at work on Saturn with Cassini."

On Earth, this relationship between distant events in a planet's climate system is known as teleconnection. Meteorological patterns across the globe are known to be delicately linked together, and can affect one another quite significantly. A key example of this is the El Niño Southern Oscillation, which can influence temperatures and climate patterns across the Earth.

"It's remarkable to see this process occurring on another planet within our Solar System—especially one that's so vastly different to our own," says Nicolas Altobelli, ESA Project Scientist for the Cassini-Huygens mission.

"Cassini-Huygens may now have ended its mission, but there's still a wealth of data to explore, and a huge amount of valuable information to be gathered from the spacecraft's observations. As well as telling us more about Saturn, gas giant planets, and the Solar System in general, this study helps us better understand the Earth. This is one key driver of our research into other planets: to discover more about our own."

Vincent Lafforgue proposes a cryptocurrency system to reward referees

We start from the following two observations:
a) the work of the referees is fundamental and deserves to be valued,
b) the difficulty that the editorial boards of the journals may have in finding referees who check the articles with the greatest care is a serious problem for the sustainability of a flawless scientific research.
Moreover b) has the following two causes (among others):
(i) the time spent by researchers in many tasks, for example administrative tasks, and especially the time wasted in the search for funding,
(ii) the excessive pressure to publish, compared to the lack of reputational rewards for referees, so that too many articles are written and they are not enough checked and improved in the refereeing process.
We suggest to create a system enabling researchers to prove, if they wish, the
referee work they did, without compromizing [sic] their anonymity as referees. We hope it would help for a) and (ii).

and

This text is just a suggestion to be studied, I do not claim it is a good idea. In particular it should not open the door to automated evaluation of research which is a very bad idea. In fact what is proposed is rather a crypto-currency system, where journals give crypto-coins to referees (both for accepted and rejected articles, and taking into account the quality of the reports). The total number of crypto-coins a journal can give is equal to the number of pages published each year, and the value of these crypto-coins would be set by research institutions, depending on the scientific level, virtue and good practices of the journals.

Google Assistant Comes To Older Android Phones

This is a pretty big deal. If you're running Android 5.0 and up, you get the Google Assistant now. Android 5.0 phones would have come out almost 4 years ago. Google is supporting Google Assistant for up to four year old devices. There are still language and country restrictions of course, but that is easy to get around. Often running the English version of the app will bypass the country restrictions and you'll be able to use the Google Assistant on your device no matter where you are in the world.

"The Florida State University-headquartered National High Magnetic Field Laboratory has shattered another world record with the testing of a 32-tesla magnet—33 percent stronger than what had previously been the world's strongest superconducting magnet used for research and more than 3,000 times stronger than a small refrigerator magnet.

On Dec. 8, this new magnet reached a magnetic field of 32 tesla. Tesla is a unit of magnetic field strength; a small refrigerator magnet is about .01 tesla.

Made of a combination of conventional low-temperature and novel high-temperature superconductors, the "32 T" will allow physicists studying materials to explore how electrons interact with each other and their atomic environment, enabling new devices that will shape our world.

For decades, the world record for a superconducting magnet has inched forward incrementally. This single leap is bigger than all the improvements made over the past 40 years combined.

"This is a transformational step in magnet technology, a true revolution in the making," said MagLab Director Greg Boebinger. "Not only will this state-of-the-art magnet design allow us to offer new experimental techniques here at the lab, but it will boost the power of other scientific tools such as X-rays and neutron scattering around the world."

It has been a remarkable year for the MagLab, noted Boebinger: The 32 T is the third world-record magnet tested in the past 13 months, following a 41.4-tesla resistive magnet tested last summer and the 36-tesla Series Connected Hybrid magnet that reached full field in November 2016".
