Think You Understand Your Dog? Think Again.
Dogs can't talk, but their body language speaks volumes. Many dogs will bow when they want to play, for instance, or lick their lips and avert their gaze when nervous or afraid.
But people aren't always good at interpreting such cues — or even noticing them, a new study suggests.
In the study, the researchers presented people with videos of a dog reacting to positive and negative stimuli, including a leash, a treat, a vacuum cleaner and a scolding. When asked to assess the dog's emotions, viewers seemed to pay more attention to the situational cues than the dog's actual behavior, even when the videos had been edited to be deliberately misleading. (In one video, for instance, a dog that appeared to be reacting to the sight of his leash had actually been shown a vacuum cleaner by his owner.)
'When it comes to just perceiving dog emotions, we think we know what's happening, but we're actually subconsciously relying on a lot of other factors,' said Holly Molinaro, who is a doctoral student at Arizona State University and the first author of the new paper, which was published on Monday in the journal Anthrozoös.
That bias could mislead owners about their dogs' well-being, Ms. Molinaro said. People who want to be attentive to their dog's experiences and emotions need to 'take a second or two to actually focus on the dog rather than everything else that's going on,' she said.
The idea for the study was born in 2021, when Ms. Molinaro was just beginning her doctoral work in canine emotions but the Covid-19 pandemic had sharply limited her ability to do in-person research.
She was inspired by studies that explore how context clues affect people's perceptions of others' emotions. She was also inspired by a distinctly pandemic-era technology: Zoom. The video conferencing software has a feature that blurs out workers' backgrounds. Ms Molinaro and her adviser, Clive Wynne — a canine-behavior expert at Arizona State — began to wonder if they could do something similar, creating videos that allowed people to see a dog's behavior without seeing what was unfolding around it.
And so, while visiting her parents in Connecticut, Ms. Molinaro began recording videos of her family dog, Oliver, a 14-year-old pointer-beagle mix, interacting with her father. In some of the videos, Ms. Molinaro's father did things that Oliver was likely to respond to positively, such as show him his leash or a toy. In others, he did things that were likely to elicit more negative reactions, such as gently scold Oliver or present him with Ms. Molinaro's cat, Saffron. ('He was not a fan,' she said.)
Then, after a crash course in video editing, Ms. Molinaro made versions of each video that removed all of the situational context, leaving footage of Oliver, alone, on a black background.
The researchers asked hundreds of undergraduates to watch both sets of videos and assess Oliver's emotional state in each clip. When the subjects evaluated the original videos, they rated Oliver's emotions as more positive in the positive scenarios than in the negative ones. But when the context was removed, they rated Oliver's emotions as equally positive in both types of situations.
Then, the scientists took things a step further by splicing together footage from different situations — showing, for instance, Ms. Molinaro's father presenting a vacuum alongside footage of Oliver's response to seeing his leash.
Viewers seemed to be swayed more by the context than by Oliver's behavior. When Ms. Molinaro's father was depicted doing something positive, subjects judged Oliver's emotions to be positive, even if he had been filmed reacting to something negative.
'There's no evidence at all that people actually see the dog,' Dr. Wynne said. 'They seem to have a sort of a big blind spot around the dog himself.'
The study has limitations, including that it was based on the behavior of just a single dog. People might also perform better when asked to evaluate the emotions of their own dogs, Dr. Wynne said, and probably would have noticed signs of intense terror or trauma. (The scientists did not subject Oliver to any extremely negative experiences.)
Still, he hoped that the study would be a wake-up call for pet owners. 'I'm taking it to heart in my own life,' said Dr. Wynne, who recently adopted a retired racing greyhound.
'I'm making it a project to learn how she expresses herself,' he added. 'Because if I know what makes her happy and unhappy, well, then I can guide her life toward greater happiness.'
Sadly, Oliver did not live long enough to see the study published. 'But it's sweet that he's memorialized in this research,' Ms. Molinaro said.

'Diving into a different world': Why an ASU professor studies the ocean in the desert
When Susanne Neuer closed her eyes, she could see it: the crystal clear waters of the Mediterranean. A smile broke out on her face as she reminisced about the times her family visited the coastline of Ibiza. She has fallen in love with the ocean over and over, each time her family visited when she was young. She pictured a life on a boat fitted with all sorts of research equipment, salt in her face and the waves beneath her feet. No land for miles and miles. And she had that life, for a little bit. Her research cruises were far from luxurious. Neuer said they were "spartan" in a way. But they were exactly what she wanted. "Just the sea in all its different states," she said. "The terrible waves that make me seasick or a smooth ocean and beautiful sunsets, and then the animals, the dolphins that come about and play in the wake of the ship," Neuer said, her cadence speeding up with excitement. "It's really diving into a different world." Neuer's life took a sharp left turn to the desert in 2000 when she landed in Arizona after her husband got a job at Arizona State University. The desert landscape was a stark difference from the glittering blue waves dotted with bioluminescent plankton. She eventually found her place in Arizona, becoming a world-renowned researcher studying the role of ocean life in the carbon cycle. In 2022, Neuer was named the founding director of Arizona State University's School of Ocean Futures, a unique position to teach desert dwellers about the ocean. Neuer, 62, grew up in southern Germany, hundreds of miles away from the ocean in all directions. But her family vacationed in Ibiza, a Spanish island, and the ocean waves lapped at the edges of her mind. She wanted to learn more about the ocean. So, she turned to the ponds and streams that surrounded her hometown, flipping over rocks and digging into the dirt and mud. When she was in her early teens, she worked one summer at a garden shop to buy her own microscope so she could uncover the mysteries in the water. It changed her life. She knew it then, that she would study the ocean and the microorganisms that were only revealed to her through the microscope on those summer days. Her university studies took her first to the University of Heidelberg in west Germany, then north to the University of Kiel on the Baltic Sea, a far cry from the warm embrace of the Mediterranean. It was one of the only places Neuer could study marine science, she said. Then, she found out about the Fulbright Program, and she was accepted at the University of Washington to study oceanography. She planned to only stay in the U.S. for a year until she met her husband on a trip to California with other Fulbright students. "I realized that, you know, that this was probably serious," Neuer said. She and her husband, who was from Spain, decided to stay and finish out their studies in the U.S. They had a daughter, finished their doctoral degrees and moved back to Germany for postdoctoral work. The family stayed in Germany for six years. "There was, back then, no way we could stay both and get both permanent positions in Germany," she said. "We said the first one who would get at tenure track offer would take the other one along." Her husband beat her to the punch. He landed a job at ASU in the middle of the Sonoran Desert, perfect for his career as a microbiologist focused on desert soil. Not so perfect for Neuer's career in oceanography. When Neuer arrived in Arizona in 2000, she was lonely. The lone oceanographer in a sea of sand and hours away from the brilliant blue ocean — again. She followed her husband's lead and got a job at ASU. She taught oceanography through the geology department and spent more time with geologists than biologists. She tried teaching as many courses about marine life as possible and ended up pioneering degrees focused on environmental and marine sciences. She fell in love with teaching, even if it meant being in the desert. She said that's a benefit, not a detriment. "You can't really understand our planet and how our planet works without the oceans," Neuer said. "(The ocean) is so intricately engrained in our climate and our weather. ... Here in Arizona, you know, we receive water that enables life in the desert, and that water has come evaporated from the ocean." As the years dragged on, she was still the only oceanographer at the university. Sure, there were biologists and geologists and other "ologists," but none focused solely on the ocean, like Neuer. She eventually found a home in the School of Life Sciences, where her programs lived for 20 years. She developed curricula for students and led the graduate program. That's how she met Jesse Senko. Senko was at ASU as a doctoral candidate studying biology in 2011. Senko, from Connecticut, had planned on staying in Arizona for four years, just long enough to get his degree. His dream was to study marine life, specifically sea turtles. He wasn't sure if he was going to make it if not for Neuer. "She provided a safe space for me," Senko said. "If it wasn't for her, I definitely would've left the school, and I don't even know if I would've gotten a Ph.D." More than 10 years later, Senko hasn't left Arizona. He hasn't even left ASU, all because of Neuer. After years of being the lone oceanographer, Neuer founded a home for people like her. Like Senko. Those passionate about the ocean while loving the desert. Neuer was named the director of ASU's School of Ocean Futures in 2022, a "180-degree turn from being the lonely oceanographer to becoming the founding director of that school," she said. The school opened in 2023 and began offering degree programs in 2024. Students are able to study from across the world, from Hawaii to Bermuda. Senko teaches at the school and leads students on research trips to Baja California in northwest Mexico to study sea turtles. "We are connected," Neuer said, "considering the ocean as a home."

A New COVID Variant Is Here, And It's More Transmissible — Here Are The Signs And Symptoms
A new COVID variant known as NB.1.8.1 has made landfall in the United States. The variant, which was first detected in China this past January, currently accounts for 10% of the SARS-CoV-2 sequences tested from around the world, recent surveillance data found. That's a significant jump from 2.5% four weeks ago. A Centers for Disease Control and Prevention (CDC) spokesperson told HuffPost that the agency is in regular contact with international partners about the activity of NB.1.8.1. To date, only 20 NB.1.8.1 sequences have been identified in the U.S. — that's below the threshold needed for a variant to appear on the agency's COVID dashboard. (As soon as its prevalence increases, NB.1.8.1 will pop up on the tracker, the spokesperson added.) It's nerve-wracking to hear that a new variant is making the rounds, but infectious disease specialists say there are no glaring differences between the symptoms of NB.1.8.1 and those caused by other versions of SARS-CoV-2. 'Currently it appears that NB.1.8.1 would have similar symptoms to other COVID variants that have recently been circulating,' Dr. Zachary Hoy, a pediatric infectious disease specialist with Pediatrix Medical Group in Nashville, Tennessee, told HuffPost. Here's what to know about the newest COVID variant that's gaining traction around the world. Compared to the currently dominant variant in the U.S. (LP.8.1), NB.1.8.1 has a handful of new mutations on the spike protein that may enhance its ability to bind to our cells, according to the World Health Organization (WHO). The agency suspects these mutations will increase the virus's transmissibility and, potentially, diminish the effectiveness of neutralizing antibodies that prevent pathogens from latching to our cells. In other words, the variant may be skilled at dodging some of our immune defenses, research suggests. According to Dr. Amesh Adalja, an infectious diseases expert and senior scholar at the Johns Hopkins University Center for Health Security, NB.1.8.1's symptoms are pretty much the same as those seen with other SARS-CoV-2 variants. Two of COVID's hallmark symptoms are a mild but persistent dry cough and nasal congestion, Hoy said. Many people who come down with COVID are also hit with fatigue and tiredness. 'An infected person can still make it through the day, but they are resting more and feel more tired throughout the day,' Hoy said. Other common symptoms include a fever, chills, a sore throat and muscle aches. 'Some have described recent variants as less intense symptoms as compared to wintertime influenza viruses, but both can have severe symptoms,' Hoy said. There's no evidence suggesting the variant causes more severe disease or an uptick in hospitalizations or deaths, the WHO states. The only noticeable aspect, as of now, is that it's rising in prevalence, Adalja said. It's too early to know exactly how effective the shots are — as the research on NB.1.8.1 is limited since it's so new — but scientists expect the shots to hold up well. NB.1.8.1 broke off from the Omicron JN.1 lineage, which the 2024-2025 vaccines target. 'The ability of the vaccines to prevent severe illness is intact though protection versus infection is limited and transient,' Adalja said. Anyone who is at risk of severe disease should stay up-to-date with the shots. 'Those in older populations or with underlying immune disorders or on immune-decreasing medications would benefit more from vaccination or those with increased exposure such as healthcare workers,' Hoy added. So if you have a condition that puts you at risk, it's worth getting vaccinated if it's been more than six months since your last vaccine or bout of COVID, Adalja advises. He also added that those who are low-risk likely do not need to go out and get another shot. Most people will be able to recover at home by resting and staying hydrated. While you're sick, acetaminophen and ibuprofen can help alleviate muscle aches and fevers, Hoy said. And, in most cases, symptoms should clear up within a week. For those who are at risk for severe disease, including older adults and people who are immune-compromised, it's worth contacting a physician as they can prescribe antivirals — Paxlovid and Molnupiravir — that can significantly lower the risk of severe complications and death. As was the case with previous variants, these antivirals work best when started within five days of symptom onset. As for when you should go to an urgent care or emergency room? When you have chest pain, have a hard time waking up or staying awake, or feel confused and disoriented, the CDC advises. Hoy says the most concerning symptom he warns patients about is difficulty breathing. 'If you have COVID or COVID-like illness and have worsening trouble breathing or chest pain, you should be evaluated at your doctor's office, urgent care or the ER,' he said.

New coronavirus discovered in China ‘only small step' from infecting humans
A new coronavirus discovered in China is only a small step from mutating and causing another global pandemic, experts have warned. Scientists believe the variant, called HKU5-CoV-2, may infect a broader range of animals than Covid-19 – which caused millions of deaths – and may have more potential for jumping between species. US researchers fear that HKU5-CoV-2, found in China, in February, could also infect humans, leading to a widespread outbreak. The new study, published in Nature Communications, looked at a lesser-known group of coronaviruses called merbecoviruses, which includes HKU5 and MERS-CoV, which is responsible for the deadly Middle East Respiratory Syndrome. The team from Washington State University looked at how the new pathogen interacts with human cells. They found that a small change in the virus's spike protein could allow it to attach to human ACE2 cells in people's throats, mouths and noses. HKU5-CoV-2 can infect and replicate inside human cells in both the airways and gut. According to the World Health Organisation, about 35 per cent of people infected with Middle East Respiratory Syndrome die. Since 2012, some 27 countries have reported cases, leading to 858 known deaths due to the infection, which spread from camels. But when HKU5 was discovered in February, scientists warned against exaggerating the risks because it does not enter human cells as readily as Sars-CoV-2, which caused Covid-19. HKU5 was first detected in bats by scientists from the Chinese laboratory where some say Covid originated in 2019. Prof Michael Letko, a virologist who co-led the study, said: 'HKU5 viruses in particular really hadn't been looked at much, but our study shows how these viruses infect cells. 'What we also found is HKU5 viruses may be only a small step away from being able to spill over into humans.' When Covid-19 emerged it was widely blamed on markets in China where different breeds of wild animal are kept caged and often slaughtered close to other animals. Meat is sold at the open-air stalls. Critics said the markets were the perfect breeding ground for new zoonotic diseases – those that spread to humans – to emerge. The scientists, whose experiments studied how the new pathogen interacts with human cells, believe the virus would have to carry certain mutations if it were to infect humans. 'These viruses are closely related to MERS, so we have to be concerned if they ever infect humans,' Prof Letko said. 'While there's no evidence they've crossed into people yet, the potential is there and that makes them worth watching.'
