Presumed Extinct, the Rare 'Golden Wonder' Salamander Reappears After 42 Years

After pulling a disappearing act for 42 years, a rare, vibrantly colored amphibian called Jackson's climbing salamander (Bolitoglossa jacksoni) was recently spotted in Guatemala's Cuchumatanes Mountains, according to LiveScience. This marks just the second time it's ever been recorded in the wild, and the third species member ever spotted.

Jackson's climbing salamander is nicknamed the "golden wonder" for its bright yellow color, and it has a thick black dorsal streak that extends from its head to its tail. Jeremy Jackson, along with his friend Paul Elias, first spotted the unique critters in 1975 while hiking through the Cuchumatanes. Their trip also led to the discovery of two additional new species, the long-limbed salamander (Nyctanolis pernix) and the Finca Chiblac salamander (Bradytriton silus).

All three creatures turned out to be exceedingly elusive. Expeditions in 2009 and 2010 yielded sightings of the long-limbed salamander and the Finca Chiblac salamander, but Jackson's climbing salamander—which Jackson had originally found hiding beneath bark in a cloud forest, according to ScienceAlert—remained hidden.

In April 2017, the nonprofit group Global Wildlife Conservation added the long-lost amphibian to its Top 25 "most wanted" species list. The list was part of the organization's Lost Species initiative, which aimed to re-discover—and potentially save—rare creatures that hadn't been seen for years, if not decades. Global Wildlife Conservation planned a January 2018 search expedition to Guatemala to look for Jackson's climbing salamander, but a Guatemalan man named Ramos León ended up beating them to the punch.

León, a guard at the Finca San Isidro Amphibian Reserve in the Cuchumatanes (also called the Yal Unin Yul Witz Reserve), was on patrol in October 2017 when he saw—and photographed—a young Jackson's climbing salamander. León then sent the picture to Carlos Vasquez, a curator of herpetology at USAC University in Guatemala.

Vasquez, who's credited with rediscovering both the Finca Chiblac salamander and the long-limbed salamander, had been been looking for Jackson's climbing salamander since 2005. He taught León and other guards how to recognize the amphibian— which likes to hide in moss, leaves or bark—and even hung a poster of the creature at the reserve.

"We had started to fear that the species was gone, and now it's like it has come back from extinction," Vasquez said in a news statement. "It's a beautiful story and marks a promised future for the conservation of this special region."

He wasn't the only one who was thrilled to hear the news. "The night I got the news from Carlos that Bolitoglossa jacksoni had been rediscovered, I flew off the couch where I'd been falling asleep, let loose a string of expletives (in a good way), and did a little happy dance," Jackson said in a news release.

Finca San Isidro Reserve was established in 2015 by an international team of wildlife preservation groups. Their goal was to protect the species' habitat, and it looks like their efforts have paid off.

"With the Cuchumatanes Range under threat—a well-known epicenter for endangered amphibians and one of the highest global conservation priorities—in 2015 we acted swiftly to support the purchase and protection of critical properties," said Paul Salaman, the CEO of Rainforest Trust, in a statement. "And we are delighted to report that this important wildlife refuge has permitted the survival and ultimate rediscovery of the spectacular Jackson's climbing salamander."

More Details Emerge About 'Oumuamua, Earth's First-Recorded Interstellar Visitor

In October, scientists using the University of Hawaii's Pan-STARRS 1 telescope sighted something extraordinary: Earth's first confirmed interstellar visitor. Originally called A/2017 U1, the once-mysterious object has a new name—'Oumuamua, according to Scientific American—and researchers continue to learn more about its physical properties. Now, a team from the University of Hawaii's Institute of Astronomy has published a detailed report of what they know so far in Nature.

Fittingly, "'Oumuamua" is Hawaiian for "a messenger from afar arriving first." 'Oumuamua's astronomical designation is 1I/2017 U1. The "I" in 1I/2017 stands for "interstellar." Until now, objects similar to 'Oumuamua were always given "C" and "A" names, which stand for either comet or asteroid. New observations have researchers concluding that 'Oumuamua is unusual for more than its far-flung origins.

It's a cigar-shaped object 10 times longer than it is wide, stretching to a half-mile long. It's also reddish in color, and is similar in some ways to some asteroids in our solar system, the BBC reports. But it's much faster, zipping through our system, and has a totally different orbit from any of those objects.

After initial indecision about whether the object was a comet or an asteroid, the researchers now believe it's an asteroid. Long ago, it might have hurtled from an unknown star system into our own.

'Oumuamua may provide astronomers with new insights into how stars and planets form. The 750,000 asteroids we know of are leftovers from the formation of our solar system, trapped by the Sun's gravity. But what if, billions of years ago, other objects escaped? 'Oumuamua shows us that it's possible; perhaps there are bits and pieces from the early years of our solar system currently visiting other stars.

The researchers say it's surprising that 'Oumuamua is an asteroid instead of a comet, given that in the Oort Cloud—an icy bubble of debris thought to surround our solar system—comets are predicted to outnumber asteroids 200 to 1 and perhaps even as high as 10,000 to 1. If our own solar system is any indication, it's more likely that a comet would take off before an asteroid would.

So where did 'Oumuamua come from? That's still unknown. It's possible it could've been bumped into our realm by a close encounter with a planet—either a smaller, nearby one, or a larger, farther one. If that's the case, the planet remains to be discovered. They believe it's more likely that 'Oumuamua was ejected from a young stellar system, location unknown. And yet, they write, "the possibility that 'Oumuamua has been orbiting the galaxy for billions of years cannot be ruled out."

As for where it's headed, The Atlantic's Marina Koren notes, "It will pass the orbit of Jupiter next May, then Neptune in 2022, and Pluto in 2024. By 2025, it will coast beyond the outer edge of the Kuiper Belt, a field of icy and rocky objects."

Last month, University of Wisconsin–Madison astronomer Ralf Kotulla and scientists from UCLA and the National Optical Astronomy Observatory (NOAO) used the WIYN Telescope on Kitt Peak, Arizona, to take some of the first pictures of 'Oumuamua. You can check them out below.

Scientists Analyze the Moods of 90,000 Songs Based on Music and Lyrics

Based on the first few seconds of a song, the part before the vocalist starts singing, you can judge whether the lyrics are more likely to detail a night of partying or a devastating breakup. The fact that musical structures can evoke certain emotions just as strongly as words can isn't a secret. But scientists now have a better idea of which language gets paired with which chords, according to their paper published in Royal Society Open Science.

For their study, researchers from Indiana University downloaded 90,000 songs from Ultimate Guitar, a site that allows users to upload the lyrics and chords from popular songs for musicians to reference. Next, they pulled data from labMT, which crowd-sources the emotional valence (positive and negative connotations) of words. They referred to the music recognition site Gracenote to determine where and when each song was produced.

Their new method for analyzing the relationship between music and lyrics confirmed long-held knowledge: that minor chords are associated with sad feelings and major chords with happy ones. Words with a negative valence, like "pain," "die," and "lost," are all more likely to fall on the minor side of the spectrum.

But outside of major chords, the researchers found that high-valence words tend to show up in a surprising place: seventh chords. These chords contain four notes at a time and can be played in both the major and minor keys. The lyrics associated with these chords are positive all around, but their mood varies slightly depending on the type of seventh. Dominant seventh chords, for example, are often paired with terms of endearment, like "baby", or "sweet." With minor seventh chords, the words "life" and "god" are overrepresented.

Using their data, the researchers also looked at how lyric and chord valence differs between genres, regions, and eras. Sixties rock ranks highest in terms of positivity while punk and metal occupy the bottom slots. As for geography, Scandinavia (think Norwegian death metal) produces the dreariest music while songs from Asia (like K-Pop) are the happiest. So if you're looking for a song to boost your mood, we suggest digging up some Asian rock music from the 1960s, and make sure it's heavy on the seventh chords.
