The Brief

The Rose Parade is right around the corner, and thousands of people are already preparing to flock to Pasadena for the New Year’s Day festivities.

In its 136th year, the parade theme is “Best Day Ever,” with tennis icon Billie Jean King as the Grand Marshal. It kicks off at 8 a.m.

Whether you’ll be camping out the night before, or heading over with blankets in tow in the early morning hours, here’s what you need to know this year.

Parade details and closures

The Rose Parade route lasts two hours, with its 5.5-mile journey starting at Green Street and Orange Grove Boulevard.

The floats, bands, and horses will head north along Orange Grove at a slow but steady 2.5 mph before turning east onto Colorado Boulevard for a majority of the show. It’ll then head north onto Sierra Madre Boulevard, wrapping up at Villa Street.

Police and city officials will close the route to cars from 10 p.m. Tuesday, Dec. 31, through 2 p.m. Wednesday, Jan. 1.

That includes Colorado Boulevard from Orange Grove Boulevard to Sierra Madre Boulevard, and Sierra Madre Boulevard to Paloma Street. So if you’ll be hosting viewing parties or are overdue for a delivery, Tournament of Roses officials recommend telling everyone to arrive before the closures kick in Tuesday night.

If you’ll need to drive to or through the downtown Pasadena area, you can use:

• Walnut Street or the 210 Freeway for east-west travel north of Colorado Boulevard
• Del Mar Boulevard or Cordova Street for east-west travel south of Colorado Boulevard
• There will be designated crossing for north-south travel during the closure (see map for details)

Please note: There will be a 5K race at midnight to celebrate the New Year from Pasadena Avenue to Hill Street. Several intersections will close to cross traffic at 11 p.m. Dec. 31 and re-open at the end of the race, including Pasadena, Fair Oaks, and Marengo avenues (see full list on map.)

Tickets

You can still snag grandstand tickets from $75 to $125, depending on where you want to sit. You’ll need to have your ticket handy.

If you’re sitting on Orange Grove Boulevard between Colorado Boulevard and Green Street, it’s “highly recommended” you get there by 6:30 a.m, according to Visit Pasadena. If your spot is west of Fair Oaks Avenue, you should aim to be seated by 7 a.m., but you should arrive in the area by at least 6 a.m. either way to give yourself plenty of time to work through the crowds.

Curbside seating and camping

Curbside seating is free, and lots of people will set up shop and camp overnight, which is only allowed on Dec. 31. If you’ll be bringing your kids or teens along, they need to be with an adult during the overnight hours.

You can grab your sidewalk spot starting at 12 p.m. Dec. 31, but all your blankets and chairs have to stay on the curb until 11 p.m., at which point you’ll be able to move up a bit closer to the blue “honor-line.” Tents, sofas, unoccupied chairs, and boxes that can be used as stools or seats are not allowed along the route.

You can warm up with a small elevated barbecue, but it needs to be away from buildings and you have to have a fire extinguisher available. Bonfires and fireworks are banned, period.

Most importantly, don’t forget to drink water and stay warm (you can always sit on that extra jacket).

Parking

There is no parking allowed on the parade route, but you can purchase reserved spots. Pasadena’s recommendations include Sharp Seating, the city itself, LAZ Parking, and AP Parking.

Public paid parking is also available on a first-come, first-serve basis near the parade route, but supply is limited (and it’ll be busy, to say the least) so plan ahead. Metro rail stations, for example, often have paid or free parking. You can check here before you head out.

All parking meters are free and time limits will not be enforced on New Year’s Day, and overnight parking restrictions will not be enforced until 2 a.m. Jan. 4, according to the city. But keep an eye out for red curbs, “No Parking” signs, fire hydrants, and driveways, the usual restrictions still apply.

As our Sharon McNary wrote in 2021 — “if there IS traffic, then YOU are the traffic.”

Public transportation

Public transit is the easiest way to go, and Metrolink will be offering special early morning hours on the San Bernardino, Antelope Valley, Orange County, Ventura County, and 91 Perris Valley lines for the parade.

You can find more information here, or by calling (800) 371-5465.

You can also take the Metro L Line (the Gold Line) to Pasadena. The closest stops are:

• Del Mar Station (walk .3 miles north to the parade route)
• Memorial Park Station (walk .2 miles south)
• Lake Station (walk .4 miles south)
• Allen Station (walk .4 miles south)

Metro will also have buses traveling to areas near the route and Rose Bowl game, which you can find more information on here, or by calling (323) 466-3876.

The agency is offering free rides from 4 a.m. Dec. 31 through 3 a.m. Jan. 1, and Metro bikes are free on Jan. 1 with the code “010125”.

Accessible viewing

Three street-level viewing areas are reserved for people with disabilities and up to four of their guests.

Each of those areas along the parade route will have a section with audio descriptions for visually impaired people and another with sign language interpreters.

Tickets are still available on the Ticketmaster resale market for the Oregon vs. Ohio State matchup. The cheapest options were going for around $235, with the best seats reaching up to $3,630 at the time of publication. Oregon fans will be in the west and north sections, with Ohio State fans in the east and south.

General parking is available in certain lots at the stadium, with spots going for $59 if you buy it in advance, or $70 on game day.

For public transportation, you can take the Metro A line and exit at the Memorial Park station. You’ll then want to follow the signs to the shuttle area at Parsons Corporation two blocks away, which will take you directly to the stadium for free.

If you’re planning to use a rideshare or taxi service, all drop-offs and pick-ups are not allowed at the stadium. You’ll need to head to Holly Street between Fair Oaks and Raymond avenues to catch the shuttle from there or walk over.

Please note: the stadium has a clear-bag policy, which means backpacks, purses, and camera cases are not allowed.

And if you have questions about closures and access, you can call the visitor hotline at (877) 793-9911. The Tournament of Roses will also be able to answer questions about resident parking passes at (626) 449-4100.

President Donald Trump said his administration will, for now, halt its efforts to deploy National Guard troops to Chicago, Los Angeles and Portland, Ore., after his deployments to the Democratic-led cities suffered a series of legal setbacks.

In a Truth Social post on Wednesday, Trump praised the deployments and claimed they have helped curtail crime.

"Portland, Los Angeles, and Chicago were GONE if it weren't for the Federal Government stepping in," he said.

The deployments in Chicago and Portland were blocked by the courts and Guard members left California after a sharp rebuke from a U.S. District Court judge earlier this month.

More recently, the Supreme Court last week ruled against the administration's emergency appeal to deploy troops to Chicago. It was the first time the high court waded into the matter. While not precedent-setting, the ruling brought some clarity to Trump's presidential powers.

Trump had argued that the Guard was needed in the Democratically led cities to quell crime and protect federal immigration officers and facilities. Democratic governors in those states staunchly opposed the deployments and federal judges were also wary of allowing the military to intervene in civilian matters.

"This principle has been foundational to the safeguarding of our fundamental liberties under the Constitution," U.S. District Court Judge Karin Immergut wrote in her November ruling freezing Trump's deployment of troops to Portland.

Trump has also deployed National Guard troops to other U.S. cities, including Washington, D.C., where more than 2,000 members of the Guard have been patrolling since August.

Those deployments have also faced legal challenges — earlier this month a federal appeals court ruled that troops can remain in the capital city while a panel of judges examines whether the deployment is legal.

A handful of Republican-led states have welcomed the Guard. In Tennessee, troops began patrolling in October. And moments after the Supreme Court ruling, Louisiana Gov. Jeff Landry said 350 troops would deploy to New Orleans. National Guard members arrived in the city Tuesday, member station WWNO reported.

In his Truth Social post on Wednesday, Trump promised, "We will come back, perhaps in a much different and stronger form, when crime begins to soar again - Only a question of time!"

Starting on Jan. 1, hundreds of new state laws will go into effect, some with the potential to shape the everyday lives of Californians. They’re meant to tackle the state’s housing affordability crisis, establish guardrails on the use of artificial intelligence and protect the sharing of personal information for those who could face federal immigration enforcement.

Most new laws won’t all bring change overnight. But some could stoke continued controversy and legal challenges. For example, if you live near public transit, one new state law will give developers the freedom to build taller, denser housing, overriding local zoning rules and potentially transforming some single-family neighborhoods. Some cities and counties remain vehemently opposed and are considering legal action.

If you’re a renter, your landlord starting Jan. 1 will be required to provide a working stove and refrigerator and keep them in working order, a nod to efforts to ease the state’s severe affordability challenges. And if you work in law enforcement or the health care field, new state laws will regulate what you can and can’t do with AI on the job.

Here’s a small sample of the many new California laws that will go into effect Jan. 1:

More housing near transit

California lawmakers approved a significant and controversial new housing law this year, Senate Bill 79. It allows for building denser, taller housing near major transit stations even in areas where local rules ban that level of development. The law will pave the way for apartment buildings as tall as 75 feet close to metro, light rail, and some bus stations. Democratic lawmakers were divided over the measure. Some argued it was necessary to speed housing development and alleviate the state’s housing shortage while others warned it would change neighborhoods of single-family homes and impact property values. Developers will officially get the green light to break ground on projects that fall under the new law starting in 2026.

Requiring stoves and fridges in rentals

While it’s quite common for rental units to include a stove and a fridge, it hasn’t been the law. Beginning Jan. 1, Assembly Bill 628 adds refrigerators and stoves to the state’s definition of a “habitable” home. This means landlords must provide them, keep them in working order and handle repairs or replacement. The rule applies to new or renewed leases. Tenants may voluntarily bring their own fridge, but they aren’t required to. The law makes exceptions for supportive housing and shared living buildings with communal kitchens. Supporters say the change is designed to improve affordability for low-income renters.

Arturo Rodriguez of the California Democratic Renters Council says this protects many renters in larger cities, where stoves and refrigerators are not included in a unit, which is more common.

“When landlords offload basic costs onto renters, it’s really destabilizing families,” said Rodriguez.

Several landlord and real-estate groups, such as the California Apartment Association and the California Association of Realtors, opposed the bill. They say new costs and installation could complicate expenses for property owners.

California’s 800,000 rideshare drivers will get the right to unionize in 2026. In turn, rideshare companies will also have drastically lower insurance costs. That’s under two new laws Governor Gavin Newsom signed after brokering a deal between labor and major rideshare companies, including Uber and Lyft. The Service Employees International Union (SEIU), which sponsored Assembly Bill 1340 to expand collective bargaining rights to gig drivers, has already reached out to drivers ahead of the law’s implementation. Senate Bill 371 will slash insurance requirements for rideshare companies for underinsured drivers from $1 million to $300,000 per incident.

Getting election results faster

Californians could see faster election results in 2026. That’s under a new law that will require election officials to count the vast majority of ballots by 13 days after election day, with exceptions for some ballots that require additional verification. There are no current requirements for counting benchmarks, just a deadline for officials to send final election results to the Secretary of State within 31 days after election day. That rule will still apply.

The new law comes as the state has seen a rise in close contests where results can take weeks. Proponents, including some election experts, say speeding up ballot counting will bolster trust in the state’s election process. “We're at the point where people are losing faith in the political process and the elections process because they hear these claims from some political leaders casting doubt on the reliability of our results, and that's a real problem,” said Kim Alexander, president of the California Voter Foundation.

Ban on AI Chatbots misrepresenting themselves as medical professionals

Starting Jan. 1, Assembly Bill 489 will make it illegal for AI Chatbots to misrepresent themselves as doctors, therapists or other licensed clinicians when people go to them for advice. This has been an emerging problem with the artificial intelligence technology available online.

The California Medical Association helped sponsor the bill. Lobbyist Stuart Thomspon told CapRadio that oftentimes vulnerable people seeking mental health advice are not aware the chatbot they are speaking to is not being monitored by a real person.

“ A lot of these chatbots will imply, or not even imply, directly state, that the patient who's interacting with them is actually interacting with a licensed mental health professional,” Thompson said. “When in fact all the content generated is purely AI.”

Assemblymember Mia Bonta is the law’s author. She said it provides safeguards for young people and elders who may have trouble discerning who they are speaking with.

 ”The world is our oyster when it comes to AI and the advancements that are being made with agentic AI,” she said, referring to artificial intelligence systems that act with autonomy. “It's very important that we are providing enough of the human in the loop to be able to ensure that those experiences end up being positive and ensure that consumers are protected.”

A spokesperson for Bonta said developers of these AI systems may be held to the same consequences as humans who impersonate medical professionals – up to a $10,000 fine and/or up to a year in prison.

Renewed Cap-and-Trade

California lawmakers passed legislation to renew the state’s cap-and-trade program — now officially calling it “cap-and-invest” — through 2045, with some amendments. The California Air Resources Board will begin rulemaking in the new year to figure out how to integrate the changes.

One change to the program allows CARB the chance to limit the distribution of free allowances. These allowances are meant to help address leakage risk, which refers to the risk that a company may decide to take its operations outside of California to avoid certain state restrictions. But critics have long said the leakage risk associated with the program is overblown, and these allowances allow companies to continue polluting.

CARB will soon announce the results of a revised assessment of the program’s leakage risk, which could guide their decisions to possibly limit free allowances after 2031.

Protecting street vendors' personal data

Senate Bill 635 aims to protect street vendors in California from having their sensitive personal data shared with the federal government as the Trump administration continues to crackdown on undocumented immigrants.

Beginning Jan. 1, state and local governments will be prohibited from voluntarily providing street vendors’ identifying information to federal immigration authorities. The law also bars local agencies from collecting information on immigration status or criminal history, or from requiring fingerprints or LiveScan background checks as part of the street vendor permitting process.

Under the new law, local authorities that collected this prohibited information prior to the law’s effective date must destroy those records by March 1.

“Street vendors are a cornerstone of our communities and contribute significantly to California’s vibrant culture and economy,” said Democratic Senator María Elena Durazo, the bill’s author. “SB 635 ensures that these hardworking entrepreneurs can operate their businesses without fear that their personal information will be turned over to immigration authorities.”

Opposition to the bill was limited during the legislative process, with critics primarily raising questions about language surrounding food safety enforcement and administrative costs rather than immigration policy.

Disclosing AI use in police reports

A new law going into effect Jan. 1 will require California law enforcement officers to disclose when they use AI to help write official reports.

Under the new law, agencies will need to provide a statement when the technology is used in a report as well as a signature from the officer involved in it.

Democratic State Senator Jesse Arreguín of Berkeley is the law’s author. Arreguín told a Senate committee earlier this year that its purpose is to promote transparency and safeguards for the new technology.

“Prosecutors, defense attorneys and courts rely heavily on police reports to determine criminal outcomes,” he said. “It's critically important that additional uses to generate a report is accurate to prevent someone’s livelihood from being wrongly impacted.”

The bill’s supporters included many criminal justice groups. Meanwhile, a few law enforcement agencies in Southern California opposed it.

Sgt. Amar Ghandi is a spokesperson for the Sacramento Sheriff's office. He said the agency does not use AI yet for helping with reports, but it isn’t out of the question in the future.

“The technology is evolving daily, at exponential, light speed,” Gandhi said. “It could come to us, but as of right now we don’t use it because again it is imperfect. There are still some things that need to be worked on and issues we have with it.”

Establishing a framework for reparations

Senate Bill 518 is a new California law that would establish the Bureau for Descendants of American Slavery.

The law was created by a 2023 task force that issued an 1,100-page document with recommendations for reparations for the descendants of enslaved people.

The law requires the bureau to create a Genealogy Division and to verify an individual's status as a descendant of slaves.

Democratic Assemblymember Corey Jackson co-authored the bill and said in July that it’s the first step in a long effort to implement reparations.

“We are not only creating a place to certify eligibility and provide education, but also laying the groundwork for future programs that can deliver remedies and opportunities for descendants.”

Legal counsel for immigrant youth

Starting Jan. 1, immigrant youth going through immigration court in California will have access to legal counsel when facing deportation. That’s because of a new law, Assembly Bill 1261, requiring the state to pay for youth legal counsel if the federal government fails to do so. The law could cost taxpayers as much as $77 million.

From backyard parties to sweaty moshpits, music lovers of all ages flocked to Riverside in the late 1980s and early 2000s to experience bands like Voodoo Glow Skulls and The Skeletones at smaller, independent venues — a community of fans, artists and promoters that shaped the city’s underground music scene before the days of the internet.

Some of that history is now on display at the Riverside Art Museum in an exhibition called “60 Miles East.” Curators Zach Cordner and Ken Crawford compiled thousands of photographs, flyers and other materials to showcase the impact of local punk, ska and hardcore bands — an era that was separate and distinct from what was happening in Los Angeles and Orange County at the time.

“ We were definitely in the shadow,” Crawford told LAist. “We kinda had to make do with hodgepodge shows and backyard bands. And then these great venues ended up emerging.”

That included places like The Barn at UC Riverside, as well as the Showcase Theatre and Spanky’s Cafe — both of which are now closed. Cordner and Crawford said they would learn about upcoming performances from friends, magazines and at record stores like the now-shuttered Mad Platter.

“As the mid nineties kind of progressed… bands were coming to Riverside finally, so we really didn't have to go too far,” Cordner said. “It was amazing.”

At the time, there was no social media to spread the word about shows, and very little internet access, which made it difficult to navigate the scene. Most people would draw maps and scribble directions to venues on the back of hand-copied flyers and posters.

“We had to actively seek it out, and hope that the map was accurate enough to actually get you there,” Cordner said. “It was definitely a more participatory thing.”

The title of the exhibition is a nod to the Inland Empire — sometimes the simplest way to describe where cities like Riverside and San Bernardino are located is to say they’re about “60 miles east” of L.A.

Ken Crawford and Zach Cordner met as kids in Riverside.

Cordner and Crawford first met as kids in the I.E. and later bonded over their shared love of skateboarding and concerts during their teen years at Riverside Polytechnic High School.

“My parents had the hangout spot and I had the car with the most seats in it, so I got to be the host and chauffeur,” Crawford said.

During that time, Cordner got hooked on photography. He was about 14 or 15 when he shot his first-ever show featuring a hardcore band called Process. That experience helped him develop relationships with other artists who would then use his prints for their albums and other promotional materials.

“After that I was just smitten,” Cordner said. “I was like, ‘This is what I want to do.’”

The pair reconnected about three decades later. Cordner now serves as publisher of Riversider Magazine, and Crawford is editor-at-large.

In 2023, Crawford said he was covering a story at the opening of a Stater Bros. when he ran into an executive at Riverside Art Museum and later pitched her the idea for “60 Miles East.”

“And we ran with it. We started collecting not only from (Zach’s) stuff but from the community,” he said. “It became very evident very quickly that curating was going to be more of an issue than collecting.”

Cordner said it took almost half a year to sort through all the materials and narrow it down — and that’s “just the tip of the iceberg” of what they have.

The exhibition "60 Miles East" runs through April 12 at the Riverside Art Museum.

Today, the music scene in Riverside is still alive, Crawford said, but it’s smaller and lacks institutional support. But thanks to social media, it’s also easier to connect with bands and to learn about events in your area.

“I mean, it's Riverside. We still have a lot of these bands here…. it's just a matter of connecting and creating a community that really fosters the scene,” Cordner said.

Part of the reason they created “60 Miles East” was to educate people on how great the underground scene in Riverside was in its heyday — and how great it can still be today.

“I really love it when I see younger generations in the exhibition, reading the walls and just soaking all of that in,” Cordner said. “Hopefully they see that and can do it, and restart it. That's my hope for it.”

The exhibition “60 Miles East” runs through April 12 at the Riverside Art Museum.

An ancient sea cow in the Persian Gulf

Cows often get a bad rap for contributing to greenhouse gas emissions, but a newly discovered species of their ocean counterparts suggests that sea cows have been key contributors to a natural climate change solution for the past 21 million years.

This long-extinct sea cow's fossil remains were discovered in Al Maszhabiya, Qatar, which is now known to be the richest fossil sea cow deposit in the world. Like today's manatees and dugongs, it mainly grazed on seagrass and was considered an "ecosystem engineer" in the coastal waters of the Persian Gulf, where it primarily lived.

With their fleshy muzzles, these mammals would browse the seafloor, grab the plants, and use their tusks to snip the roots and eat them. In the process, they lift up nutrients from the seafloor that would otherwise be buried, which other animals in the ecosystem can use. These nutrients, in addition to the sea cow's excrement, help cultivate a healthier and more diverse ecosystem.

"Supporting seagrass communities through ecosystem engineering is a great natural climate solution, because seagrass communities store an incredible amount of carbon," says Nicholas Pyenson, curator of fossil marine mammals at the Smithsonian's National Museum of Natural History.

The name of the new species, Salwasiren qatarensis, honors the fossil's discovery site in Qatar, and the Bay of Salwa in the Persian Gulf, where the largest herd of dugongs can be found today. But Pyenson says Salwa, an Arabic word which roughly translates to "solace," is also a nod to the potential for the new species to "elevate the visibility and protection of natural heritage," adding that "natural heritage doesn't actually, in all cases, respect geopolitical boundaries."

Pyenson is referring to the fact that the seagrass meadow in the Bay of Salwa spans the coasts of Qatar, Saudi Arabia and Bahrain. His colleagues are currently in the process of applying for UNESCO World Heritage status to protect the region.

"This is a great example of science diplomacy," Pyenson says, "where data sharing, making data open access and available when you publish, has the potential to actually form a metaphorical bridge between countries that maybe have not historically seen eye to eye."

A mini marsupial in the Andes Mountains

This new species of mouse opossum, called Marmosa chachapoya, has bright reddish fur and a long and delicate snout which distinguishes it from its closest relatives.

A beady-eyed mouse opossum living high up in the Peruvian Andes wasn't what Silvia Pavan initially set out to find during her expedition in Río Abiseo National Park, but the new species gives yet another reason why this special region is protected as a UNESCO World Heritage site.

Pavan, an assistant professor at Cal Poly Humboldt, was on the hunt for a specific squirrel species when she and her colleagues came across an animal they eventually named Marmosa chachapoya to honor the Chachapoya people who formerly occupied the area.

The tiny marsupial (which, despite its scientific name, is not a marmoset) was the first small mammal that the researchers collected on their trip. While the animal looked a lot like a mouse opossum, its long and delicate snout and home high in the mountains set it apart from other marmosa species. But once Pavan brought the samples back, DNA analysis — coupled with a close examination of its skull — proved that this was indeed a new species.

The high-altitude area of the mountains where the expedition took place is difficult to access, but Pavan says these underexplored areas are even more important to study: "We do not know yet completely what we have, and it highlights how much we still need to explore and study the area, and how unique and important [it] is for biodiversity."

With the threat of climate change and human impact, Pavan says, "the species are being lost before we know they exist."

On this trip alone, the team of researchers collected roughly 100 different specimens that they are continuing to identify.

An undercover spider in Northern California

Marshal Hedin discovered this brown spider, Siskiyu armilla, along the river near where he grew up.

Marshal Hedin was walking along the river near where he grew up in Northern California when he came across a spider he hadn't seen before. Fifteen years later, the professor of biology at San Diego State University finally got to identify it as a new species of an entirely new genus, which he named after his home of Siskiyou County.

Brown spider species like Siskiyu armilla are very difficult to tell apart using only their physical characteristics. Many species look similar because they live in the same kind of habitat: under rocks or in other dark, humid places.

To make sure the spider Hedin found was genetically different from existing species, he and his colleagues decided to perform a DNA analysis. So he returned to the river to search for a new specimen of the rare spider (and brought his son along with him, too).

Coauthor Rodrigo Monjaraz Ruedas, an assistant curator of entomology at the Natural History Museum in Los Angeles who focused on the DNA analysis, was surprised to find that there was such a huge diversity of spider species in the area.

He says that if we simply assume that spiders that look similar are the same species without actually examining their DNA, "we're going to be missing a lot of the actual diversity these spiders have."

California plays an especially important role in this diversity, according to Monjaraz Ruedas. As part of a project from the California Institute of Biodiversity, which hasn't yet been published, he has found that close to 40% of the total number of described species of spiders in the U.S. can be found in the state.

Hedin, who was once oblivious to the diversity of species his home boasts, says that this journey has brought him full circle: "Now I know that it's a very unique place." He hopes that this discovery shows the other folks living along the river how special their home is.

And "this is just the tip of the iceberg," Monjaraz Ruedas says, because they're still examining 40 to 50 other spiders that might also be new species.

A smiley snailfish from the deep sea

The bumpy snailfish, Careproctus colliculi, was officially described by MBARI researchers this year.

(

MBARI

)

Nearly 11,000 feet into the deep sea, scientists discovered a new species that caught the attention — and affection — of viewers from around the world. The bumpy snailfish was captured on video by researchers at the Monterey Bay Aquarium Research Institute during their expedition off the shores of Central California — and with its big eyes, feathery fins and a mouth bearing the suggestion of a smile, it was an instant hit.

To help determine if the floppy pink sea creature was new or one of the 400 existing species of snailfish, they assembled a team of scientists, including Mackenzie Gerringer, an associate professor of biology at the State University of New York at Geneseo.

Even though Gerringer has "never met a snailfish [she] didn't love," she knows that the deep sea, where some of the species live, is seen as a bit of an alien environment by many people, which can come with a negative connotation.

She says the new species can help people question their assumptions about the deep sea because "you're left with these fishes that are, in my opinion, quite cute, and they really look quite fragile in an environment that we think of as being very harsh."

The research team also identified two other species of snailfish, which Gerringer says highlights just how much there still is to learn about the deep sea.

While discovering a new species can be very exciting, Gerringer believes the importance of the practice goes beyond that.

"It's critical to know who is in these ecosystems, so that we can understand how they're working, so that we can protect habitats like the deep sea that we know play hugely important roles," she says. Some of those roles, including the deep sea's ability to store enormous amounts of carbon, are especially important given the threat of climate change.

Many people remember learning about the typical life cycle of frogs and toads in elementary school: Eggs turn into tadpoles, which eventually become adults. But scientists have found three new species of toads in Tanzania that do something very unusual: they give birth to live young.

Another striking thing about these new species, which are all part of the genus Nectophrynoides: The journey to discover them took over 100 years. The first toad in this genus was described in the early 1900s, and because all the specimens collected looked so similar, they were all thought to belong to a singular species.

But Christoph Liedtke, an academic researcher from the Spanish National Research Council who has spent the last decade studying these toads, wondered whether there was more biodiversity in the highlands of the Eastern Arc mountains of Tanzania than previously thought. So he and his colleagues tried to see if there was more than one species in the Nectophrynoides genus.

This was no easy task because many of the specimens they needed to examine and compare to modern-day samples were collected before the time of DNA sequencing. Coauthor John Lyakurwa, an assistant lecturer at the University of Dar es Salaam, says that the process was like a "big puzzle that we had to solve."

So they teamed up with researchers from Denmark and Belgium to extract DNA from over 200 museum specimens. From there, they used next-generation sequencing to identify three new species in the genus, which was more than previously thought.

It's not clear how these toads will fare in the future. Like many species, their populations are in decline, with one species already extinct and others not being spotted for the past 20 years. For his PhD thesis, Lyakurwa has been focusing on understanding why these toad populations have been shrinking. Especially because of their unusual method of reproduction, he stresses that "if we lose them, we lose a very big evolutionary history."
