Mystic Aquarium scientist to lead research expedition to underwater canyons ‘deeper than the Grand Canyon'
The scientists 'will study predator-prey interactions, collect and identify gelatinous zooplankton, conduct seabird population surveys, and collect environmental DNA to measure biodiversity,' according to Mystic Aquarium. They will travel on the Research Vessel Connecticut to explore the monument and collect data.
'Dr. Peter Auster, Scientist-in-Residence at Mystic Aquarium and Research Professor Emeritus at the University of Connecticut, will lead the expedition,' according to Mystic Aquarium. 'The team is comprised of scientists and educators representing organizations including Yale University, University of Rhode Island, University of Connecticut, the U.S. Fish and Wildlife Service, and University of Maryland Center for Environmental Science.'
The monument, a government-established marine protected area, is 'the first and only Marine National Monument off the continental United States,' according to the aquarium. It ' features three underwater canyons deeper than the Grand Canyon' as well as four seamounts, or extinct volcanoes, 'that rise higher than any mountain east of the Rockies.'
The environment allows refuge for marine life, according to Mystic Aquarium, which includes 'endangered marine mammals, sea turtles, seabirds, and many species of rare and fragile deep-sea corals, some thousands of years old.'
'The monument is located approximately 130 miles off Cape Cod and spans an area roughly the size of Connecticut,' according to the aquarium.
This CT baker uses an ingredient that's growing broadly in popularity. There's a reason she does it.
'The monument is a living laboratory, sitting in an undisturbed, remote location where migrating whales, sea turtles, sea birds and other species representing a large portion of the food web gather to eat, breed, and find shelter,' said Dr. Peter Auster, the expedition's chief scientist and principal investigator. 'As our oceans are rapidly changing, MPAs like the monument allow us to collect essential data to inform conservation strategies.'
'Marine protected areas are one of the most valuable ocean research and conservation tools we have, offering an unmatched opportunity to study how the ocean works in the absence of human disturbance and showcase its rich biodiversity,' said Katie Cubina, Education and Outreach Consultant for Mystic Aquarium. 'There is something in the ocean for everyone, whether it's the protection of endangered marine animals, scientific discoveries, or simply appreciating its intrinsic beauty.'

Dogs are helping people regulate stress even more than expected, research shows
In a 2022 survey of 3,000 U.S. adults, more than one-third of respondents reported that on most days, they feel 'completely overwhelmed' by stress. At the same time, a growing body of research is documenting the negative health consequences of higher stress levels, which include increased rates of cancer, heart disease, autoimmune conditions and even dementia. Assuming people's daily lives are unlikely to get less stressful anytime soon, simple and effective ways to mitigate these effects are needed. This is where dogs can help. As researchers at the University of Denver's Institute for Human-Animal Connection, we study the effects animal companions have on their humans. Dozens of studies over the last 40 years have confirmed that pet dogs help humans feel more relaxed. This would explain the growing phenomenon of people relying on emotional support dogs to assist them in navigating everyday life. Dog owners have also been shown to have a 24% lower risk of death and a four times greater chance of surviving for at least a year after a heart attack. Now, a new study that we conducted with a team of colleagues suggests that dogs might have a deeper and more biologically complex effect on humans than scientists previously believed. And this complexity may have profound implications for human health. How stress works The human response to stress is a finely tuned and coordinated set of various physiological pathways. Previous studies of the effects of dogs on human stress focused on just one pathway at a time. For our study, we zoomed out a bit and measured multiple biological indicators of the body's state, or biomarkers, from both of the body's major stress pathways. This allowed us to get a more complete picture of how a dog's presence affects stress in the human body. The stress pathways we measured are the hypothalamic-pituitary-adrenal, or HPA, axis and the sympathoadrenal medullary, or SAM, axis. When a person experiences a stressful event, the SAM axis acts quickly, triggering a 'fight or flight' response that includes a surge of adrenaline, leading to a burst of energy that helps us meet threats. This response can be measured through an enzyme called alpha-amylase. At the same time, but a little more slowly, the HPA axis activates the adrenal glands to produce the hormone cortisol. This can help a person meet threats that might last for hours or even days. If everything goes well, when the danger ends, both axes settle down, and the body goes back to its calm state. While stress can be an uncomfortable feeling, it has been important to human survival. Our hunter-gatherer ancestors had to respond effectively to acute stress events like an animal attack. In such instances, over-responding could be as ineffective as under-responding. Staying in an optimal stress response zone maximized humans' chances of survival. More to the story After cortisol is released by the adrenal glands, it eventually makes its way into your saliva, making it an easily accessible biomarker to track responses. Because of this, most research on dogs and stress has focused on salivary cortisol alone. For example, several studies have found that people exposed to a stressful situation have a lower cortisol response if they're with a dog than if they're alone – even lower than if they're with a friend. While these studies have shown that having a dog nearby can lower cortisol levels during a stressful event, suggesting the person is calmer, we suspected that was just part of the story. What our study measured For our study, we recruited about 40 dog owners to participate in a 15-minute gold standard laboratory stress test. This involves public speaking and oral math in front of a panel of expressionless people posing as behavioral specialists. The participants were randomly assigned to bring their dogs to the lab with them or to leave their dogs at home. We measured cortisol in blood samples taken before, immediately after and about 45 minutes following the test as a biomarker of HPA axis activity. And unlike previous studies, we also measured the enzyme alpha-amylase in the same blood samples as a biomarker of the SAM axis. As expected based on previous studies, the people who had their dog with them showed lower cortisol spikes. But we also found that people with their dog experienced a clear spike of alpha-amylase, while those without their dog showed almost no response. No response may sound like a good thing, but in fact, a flat alpha-amylase response can be a sign of a dysregulated response to stress, often seen in people experiencing high stress responses, chronic stress or even PTSD. This lack of response is caused by chronic or overwhelming stress that can change how our nervous system responds to stressors. In contrast, the participants with their dogs had a more balanced response: Their cortisol didn't spike too high, but their alpha-amylase still activated. This shows that they were alert and engaged throughout the test, then able to return to normal within 45 minutes. That's the sweet spot for handling stress effectively. Our research suggests that our canine companions keep us in a healthy zone of stress response. Dogs and human health This more nuanced understanding of the biological effects of dogs on the human stress response opens up exciting possibilities. Based on the results of our study, our team has begun a new study using thousands of biomarkers to delve deeper into the biology of how psychiatric service dogs reduce PTSD in military veterans. But one thing is already clear: Dogs aren't just good company. They might just be one of the most accessible and effective tools for staying healthy in a stressful world.

Huge Study Reveals 2 Vaccines That Appear to Reduce Dementia Risk
Some immunizations may be quietly protecting us from cognitive decline. How the medicine might do that is a mystery scientists are desperate to solve. A new study on two vaccines for older adults gives us a crucial clue. The retrospective cohort study included more than 130,000 people in the US. It reveals that the shingles vaccine (called Shingrix) and the respiratory syncytial virus (RSV) vaccine (Arexyv) are associated with a reduced risk of dementia compared to the annual flu vaccine. Related: Both Shingrix and Arexyv are recommended for older adults, and they contain the AS01 adjuvant, which helps stimulate the immune system after vaccination. The flu vaccine does not. Because the link to dementia was noticed soon after receiving the jab, it's unlikely that the vaccines' protection from direct viral exposure is behind the dementia link. Instead, the findings from the University of Oxford suggest "that the AS01 adjuvant itself plays a direct role in lowering dementia risk." Within 18 months of receiving just the Shingrix vaccine, participants showed an 18 percent reduction in dementia risk compared to those who received only the flu vaccine. Meanwhile, those who received the RSV vaccine showed a 29 percent reduction in dementia risk compared to the flu vaccine. Participants who received both the Shingrix and the Arexyv vaccine showed a 37 percent reduction in risk. This combined effect was not statistically greater than one vaccine on its own. In other words, protection from two viruses didn't significantly increase the protection against dementia. The findings suggest that some vaccines "protect against dementia through mechanisms unrelated to (or at least in addition to) the prevention of their [target virus]", write the study authors, led by psychiatrist Maxime Taquet from the University of Oxford. If that's true, then certain vaccines may protect against dementia by triggering important pathways in the immune system. The conclusions align with an emerging hypothesis: that dementia is not actually a brain disease but a disorder of the immune system within the brain. Perhaps vaccines can help get that system up and running again, even if a threatening virus never comes along. In recent years, studies have shown that exposure to several common viruses, like those behind cold sores, shingles, mono, pneumonia, and COVID-19, can lead to a higher risk of cognitive decline down the road. Moreover, vaccines seem to reduce that risk by a significant amount. But why that is has remained a mystery. In 2024, for instance, a study from the United Kingdom found that Shingrix delayed dementia onset by 17 percent compared to older, less effective shingles vaccines. At the time, this was interpreted as indicating that the more effective a shingles vaccine is at reducing viral exposure, the more the brain is protected against cognitive decline. This older version of the shingles vaccine (called Zostavax), however, doesn't include the AS01 immune-booster, and that may have influenced the results. In the US, it is generally recommended that adults over the age 50 receive two doses of the shingles vaccine to protect themselves against the varicella-zoster virus. This is the same virus that causes chicken pox, and it can lie latent in the brain for years before re-emerging in adults. It is also recommended that adults over age 75 receive the RSV vaccine. Both of these vaccines can protect from dangerous infections, but it seems that may not be all they do. "It is likely that both the AS01 shingles and RSV vaccines provide some protection against dementia," conclude Taquet and his colleagues. "The mechanisms underpinning this protection remain to be determined." Vaccines have saved a staggering 154 million lives around the world in the last half century from deadly viruses. If we're lucky, that's just the tip of the iceberg. The study was published in npj Vaccines.
