Bird Flu: A New Threat Emerges for Marine Mammals

Bird flu isn’t just lurking inside cows, new research shows. Florida scientists have reported the first known case of highly pathogenic H5N1 avian influenza in a common bottlenose dolphin (Tursiops truncatus). This groundbreaking discovery underscores the potential threat bird flu strains pose to a wide variety of mammals.

The findings, published in the Nature Communications Biology journal, reveal that this unique case dates back to 2022 when researchers from the University of Florida’s Marine Animal Rescue Program identified a dolphin in distress near Horseshoe Beach, North Florida. Tragically, by the time they reached the site, the marine mammal had already succumbed. An autopsy performed at the university uncovered signs of poor health and inflammation in its brain and meninges.

Puzzled by their initial findings and driven by pre

Vienna (OTS) – Immunology Day is celebrated worldwide on April 29th. This day of action is intended to raise awareness of the importance of immunology and immunological research in the fight for lifelong health and individual well-being. This year’s theme is: Immunity and Aging: Navigating the Science of Aging and Immunology! The Austrian Society for Allergology and Immunology (ÖGAI) is the national expert platform for scientifically proven information on immunology topics and provides recommendations for both doctors and the general public free of charge.

Worldwide, the proportion of people over 60 in the population is increasing rapidly. By 2030 it will already be around a third. The performance of the immune system can decline, particularly as we get older. This year, “Immunology Day” is dedicated to the topic of healthy aging and provides information about how the immune system influences the aging process.

Research groups in Austria are also working on the topic. The Research Institute for Biomedical Aging Research The University of Innsbruck’s goal is to help people grow old with dignity and good health. The aim of the research is to investigate aging processes at the molecular, cellular and organismic level in order to better understand age-related changes and impairments. The working group of Prof. Dr. Birgit Weinberger, for example, resea

Music, that universal language capable of touching the soul, can be a possible remedy against insomnia, a condition that causes so many disorders. According to science, there is a song that is the best for falling asleep.

If you suffer from insomnia, it is not a good idea to go to bed on an empty stomach: three foods that help you fall asleep

According to the National Heart, Lung, and Blood Institute, insomnia is a common condition characterized by problems falling asleep, staying asleep, or getting a restful night’s rest.

That same body explains that it not only prevents falling asleep or maintaining it, but also affects the quality of life, generates fatigue, daytime sleepiness, and its duration can vary from days to weeks.

This disorder, which can be triggered by stress or changes in routine, has a cure in music, offering a sweet melody to calm the mind and promote rest.

What music is good for sleeping?

Music offers an effective remedy for insomnia, resulting in a significant improvement in quality of life.

According to the Body Mind website, certain melodies can exert a calming effect comparable to that of anti-anxiety and sedative medications used in surgeries with local anesthesia.

Researchers from the University of Pennsylvania, cited by the health portal, confirmed this with a specific piece of music.

What is the best song to sleep with?

The study mentioned by the portal compared the effects of the benzodiazepine with those of the subject Weightlessrecognized as the most relaxing song in the world.

The results indicated that music could be a viable alternative to using medications to manage anxiety.

“Weightless,” the song used by researchers at the University of Pennsylvania in a clinical trial with patients, is a work by the British group Marconi Union.

This piece, according to Body Mind, was studied by neuroscientists from Mindlab International, led by Dr. David Lewis-Hodgson, to identify the most relaxing songs.

When comparing 10 compositions and measuring their impact on the physiological constants of 20 individuals, “Weightless” stood out for reducing anxiety by 65%, the most signific

The whole world is suffering from dengue fever infection. According to the World Health Organization (WHO), 100 to 400 million people are infected with dengue fever every year, which is an eight-fold increase compared to 20 years ago. The reason dengue fever is spreading so quickly is because climate warming has allowed mosquitoes to breed in more areas.

In this situation, a startup called Birdview, based in Sao Paulo, Brazil, one of the countries most affected by dengue fever, decided to prevent the spread of dengue fever by releasing sterile male mosquitoes using

A worrying trend has emerged among girls under 12 years old, dubbed “Sephora Kids,” who have become addicted consumers of facial care, makeup, and beauty products. Large pharmaceutical companies in countries like Sweden are imposing age restrictions to curb this phenomenon and prevent premature use of cosmetics.

Bird flu found in dolphins: What does it mean for mammals and public health?

In a groundbreaking discovery, Florida scientists have reported the first known case of highly pathogenic H5N1 avian influenza in a common bottlenose dolphin. This finding raises concerns about the potential for flu strains to infect a wide range of mammals, including humans.

The research, published in the journal Communications Biology, details the case of a dolphin that was found to be infected with H5N1 in March 2022. The dolphin, which was already deceased by the time researchers arrived, exhibited signs of poor health and inflammation in its brain and spinal cord membranes.

This discovery is significant as it confirms the ability of avian flu strains to cross the species barrier to marine mammals. While there have been previous sightings of highly pathogenic avian influenza in marine mammals such as harbor seals, this is the first recorded case in a common bottlenose dolphin within North American waters.

It is important to note that not all bird flu strains pose the same level of risk to other animals they infect. Current outbreaks of H5N1 bird flu in cows, for example, have caused relatively mild illness. However, strains belonging to the lineage of H5N1 found in the dolphin have proven to be deadly to marine mammals.

Although the strain identified in this case did not exhibit known genetic changes that would enhance its ability to infect and spread among mammals, the rapid mutation rate of flu vi
