State officials unveil secret weapon to take down dangerous invasive species: 'They picked the right breed for the job'
Officials in British Columbia, Canada, campaigning against a destructive invasive species have unveiled their secret weapon: a very good boy.
Zebra mussels are native to Russia and Ukraine but have spread throughout Europe and North America. Like other invasive species, they destroy ecosystems by outcompeting native fauna for resources and reproducing in vast numbers.
As the National Park Service noted, a large population can rapidly clear a body of water of its floating particles, damaging the food web.
Zebra mussels spread into new areas by hitching rides on boats they attach themselves to. Because of robust preventative measures in place, they haven't yet spread to British Columbia.
As the Agassiz-Harrison Observer reported, boat owners must clean off all plants, animals, and mud, drain all water, and dry their vessels before returning to the sea. But it's too easy for the naked human eye to miss a zebra mussel attached to a boat. That's where the dogs come in.
Specially trained sniffer dogs can easily detect the tiny pests. The May 6 demonstration showed a German shepherd named Major finding a hidden mussel on a boat at Cultus Lake.
The discovery was especially valuable since quagga and zebra mussels are hardy critters. As a local official told the Observer, mussels "can survive out of water for potentially up to 30 days."
Using dogs in conservation efforts is a natural fit; helping humans comes naturally to our canine friends. Another example can be found in South Africa, where a clever border collie named Jessie sniffed out a species experts thought had disappeared 80 years ago.
Dogs and local community action are a powerful combination in the fight against invasive species. In Ontario, locals came together to remove a million invasive snails from the waterways.
With 225 million scent receptors (humans have only 6 million), German shepherds have one of the strongest noses among dogs. This, combined with their high intelligence, is why they're commonly used by law enforcement.
Should we be actively working to kill invasive species?
Absolutely
It depends on the species
I don't know
No — leave nature alone

Some Black Holes May Be Portals Through Spacetime In Disguise
Here's what you'll learn when you read this story: Theoretical physicists have long debated the possible existence of wormholes, which are mathematically possible, but no evidence points to their physical existence. One theory suggests that these hypothetical tunnels in spacetime could be masquerading as black holes, as both objects share similar characteristics as a result of existing right on the edge of where known physics breaks down. A new study adds more evidence to this conjecture by analyzing quasi-normal modes—distinctive vibrations in space-time caused by temporary perturbations—and finds that wormholes could mimic black holes in this particular context. Although traversable wormholes are a popular trope in sci-fi, the space-time structures that connect two different points of the universe are—at least, as of now—completely hypothetical. One of the first types of wormholes ever theorized, the Einstein-Rosen bridge, is simply a specific solution to Einstein's field equations, which map space-time geometry within certain matter and energy conditions. Sadly, these sci-fi dreams rest on the fantastical concept of 'negative energy,' a cosmic phenomenon that simply doesn't exist in the classical universe (though the answer isn't so clear cut in the quantum realm). Due to the space-time strangeness required to form a stable wormhole, some scientists have considered whether certain black holes might actually be wormholes in disguise. Although physical reality makes this a near-impossibility, mathematics shows that it's at least conceivable. Now, a new study has analyzed a certain attribute of Schwarzschild black holes—which are named for German physicist Karl Schwarzschild and are themselves hypothetical objects, as they're black holes that contain no rotation or electric field—known as quasi-normal modes (QNMs). These modes are considered quasi-normal because they describe distinctive vibrations of space-time when a compact object is perturbed (i.e. they don't continue indefinitely). Using different approaches—including a parameterization to define the properties of the area near the 'throat' of a wormhole while analyzing three different perturbation types (scalar, axial gravitational, and electromagnetic)—the researchers concluded that a wormhole could consistently replicate the QNMs associated with static (a.k.a. Schwarzschild) black holes. The results of the study were uploaded to the preprint server arXiv, and the authors note that the study will soon be published in the journal Physical Review D. 'Exotic compact objects—either beyond General Relativity (GR) predictions or arising from unconventional GR assumptions—could theoretically exist, though they remain undetected,' the authors wrote. 'This elusiveness may be due to their ability to closely mimic the observational properties of black holes.' The idea of wormholes masquerading as black holes of all shapes and sizes isn't a new one—in fact, it's a theory that's been debated for decades. More recently, a 2021 study pondered whether active galactic nuclei, or AGN, are actually wormhole mouths rather than supermassive black holes. A year later, a team from Sofia University in Bulgaria concluded that light emitted from a disk surrounding a traversable wormhole would likely be 'nearly identical' to that of a static black hole. Long-standing theories have also wondered if black holes could be paired with mirror twins, known as 'white holes,' which would together form wormholes. Of course, white holes have never been observed or detected either, but once again, the math allows for their existence. This new study adds to that growing discussion by analyzing the QNM aspect of static black holes and finding that the two are also similar. 'We can say that a wormhole can effectively emulate the Schwarzschild black hole in general relativity in its fundamental mode and first overtone across the three distinct perturbation types considered individually,' the authors wrote. The authors also expect to build on this approach by improving near-throat parameters and analyzing the polar gravitational perturbations theoretically exhibited by both wormholes and black holes (though the problem presents a few computational difficulties that will need solving). For now, wormholes remain firmly in the realm of science fiction. But with mathematics continuing to prove that such objects are possible, scientists will continue to search for these bridges across the universe.

Flight hit by violent turbulence, forcing emergency landing in Germany and injuring 9 people
Severe storms in southern Germany forced a Ryanair flight to make an emergency landing late Wednesday after violent turbulence injured nine people on board, German police said in a statement Thursday. The flight, traveling from Berlin to Milan with 179 passengers and six crew members, encountered turbulence so intense around 8:30 p.m. that the pilot was forced to make an unscheduled landing at Memmingen Airport in Bavaria, a region of southern Germany. Eight passengers and one crew member were hurt. Three people were taken to the hospital in Memmingen for treatment; the other injured people were released after receiving outpatient treatment. As a precaution, all passengers were checked for injuries by the emergency services. Authorities did not permit the plane to continue flying, and the airline arranged bus transport for passengers. Milan is about 236 miles south of Memmingen. It's the latest in a string of notable incidents where severe turbulence has grounded planes and injured or even killed passengers. A Scandinavian Airlines flight from Sweden to Miami had to turn around and return to Europe after hitting turbulence over Greenland in November last year. No injuries were reported, but photos showed debris scattered around the plane's interior. Earlier last year, over 100 passengers were injured and one was killed when a Singapore Airlines flight hit clear-air turbulence while flying from London to Singapore. The flight was diverted to Bangkok, where some passengers were hospitalized. Turbulence is more common in the warmer summer months, Taylor Garland, spokesperson for the Association of Flight Attendants, told CBS News in 2022. Passengers can stay safe by listening to pilots and flight attendants and staying seated and buckled in when the seatbelt sign is on, Garland said. "That seatbelt sign comes on for a reason. You should not be up or going to the bathroom," Garland said. "That sign is on for your safety, but some passengers may think 'Oh, I'll be fine,' but with turbulence, you can injure yourself and other people around you." Elsewhere in southern Germany, storms damaged several homes in Ulm, Baden-Württemberg, according to the German news agency dpa. In the Donaustetten district, strong winds tore roofs off multiple row houses, rendering them uninhabitable, though no injuries were reported. Fire officials suspect a small tornado or waterspout caused the damage. The German Weather Service is investigating, according to dpa. Storm-related emergency calls also came from other areas in southern Germany, where damage was mostly limited to fallen trees and flooded basements. The weather service warned of further storms Thursday, with hail, strong winds, and localized heavy rain expected.

Researchers make critical breakthrough after using powerful satellite to track dangerous pollution: 'Large-scale missions'
Research published this March in the journal Environmental Research Letters has demonstrated an impressive new way to zero in on heavy polluters and monitor evolving pollution problems, according to a release via Researchers at the Max Planck Institute and Heidelberg University have established a method for using a German satellite, the Environmental Mapping and Analysis Program, or EnMAP, to determine the amount of atmospheric carbon dioxide (CO2) and nitrogen dioxide (NO2) present in the same area "with an unprecedented spatial resolution." These common air pollutants are generally released from the same source, so measuring one or the other independently has been challenging to date. This team leveraged the new technique to assess emissions from power plants. The technology used for such measurements has typically "only [achieved] a spatial resolution of 3 to 5 kilometers" (about 1.9 to 3.1 miles), according to the release. But the EnMAP can achieve an "exceptionally high level of spatial detail" of a 30-meter (98-foot) square, producing more precise and usable data. NO2 isn't technically a greenhouse gas like CO2, methane (CH4), or nitrous oxide (N2O), though it is harmful when in the home. Meanwhile, because NO2 is so often emitted alongside CO2, it is often used to measure CO2 based on an assumed ratio. With independent measuring made possible with the EnMAP, readings can now provide more accurate and insightful information. The EnMAP has been in the sky for three years as of April and has been key to numerous climate-related studies. The paper's co-authors are hopeful about the future applications of the method they have developed using the satellite. "Our study shows how satellites with high spatial resolution can contribute to the targeted monitoring of industrial emissions in the future—in addition to large-scale missions such as the European CO2M satellite," said research leader Thomas Wagner in a statement. With accurate data being key to catching polluters as well as tracking potential improvements, there's the possibility for innovative measurement techniques to play a role in not only penalties for offenders but also in setting more pro-environment policies down the line.
