More than 17,000 southern elephant seal pups, about 95% of the total number of seals born last year, died on Argentina’s Valdez Peninsula from a highly contagious strain of the virus. H5N1, or bird flu. According to publications V Live Sciencean outbreak of avian influenza has been confirmed by the Argentine Government Animal Health Service (SENASA), and against this background, suspicions arose among environmentalists and scientists that the virus had mutated and was able to transmit from mammal to mammal.

According to the researchers, a catastrophic jump in mortality among elephant seal pups occurred in November last year. It is noted that their young are born between September and November and remain with their mother for the next three weeks.

Scientists obtained data from three zones on the Valdez Peninsula, which includes about 500 kilometers of coastline. Experts found that 96% of the cubs of this species in the studied areas died. According to scientists, about 18 thousand new individuals were born in 2022, which suggests that almost the entire young population was lost.

Researchers do not yet know how the disease affects adults, but their research work, presented in Marine Mammal Science, states that on one of the densely populated beaches, 46 deaths were recorded among adult elephant seals, although even one such death is rare in a year. Scientists explain the incident by the transmission of the virus from mammal to mammal, which could have happened when the disease was transmitted from sea lions to elephant seals.

Aromatic chicken broth is often recommended for colds. However, is it really that useful?

In the 21st century, it may seem that this is just a placebo that makes the process of fighting infection a little more comfortable. However, this is only partly true.

In 1998, doctors proved that chicken broth helps improve the function of cilia – special structures in the human nose that prevent foreign bodies from entering the respiratory tract. And the vegetables contained in the broth enrich it with nutrients that strengthen the immune system.

This remedy will clearly not harm a person who is already sick. In addition, it is a wonderful source of calories that the body can easily absorb even when unwell. The broth also contains glucosamine, one of the main building blocks of the digestive system, released from bones during heat treatment. The cooled broth forms a jelly-like substance, which is precisely a combination of gelatin and glucosamine, which additionally protects the mucous membrane of the digestive tract.

The broth also contains carnosine and chondroitin. The first eliminates nasal and throat congestion, and the second, together with glucosamine, is an extract of joint and ligament tissue.

Thus, chicken broth is, of course, not a medicine that cures an infection, but it serves as a good help for an ailing body and simply improves mood.

Fresh publication V JAMA Neurology says, scientists from the University of Maastricht in the Netherlands, with the assistance of British colleagues, analyzed data from more than 350 thousand participants in the UK biobank, during which they identified 15 factors that are directly related to an increased risk of dementia under the age of 65, which is considered young.

It is noted that as part of the work, data from over 350 thousand people was studied, the majority of which, namely just over 55%, were women. The average age of people was about 55 years. There were 485 deaths identified during the study period, and of the 39 risk factors initially selected, 30 were significantly associated with the development of early-onset dementia.

The key factors that can lead to the development of a dangerous disease are low levels of education and socio-economic status. In addition, the scientists determined that moderate or heavy alcohol consumption was less associated with the risk of developing a dangerous disease compared to complete abstinence from alcoholic beverages or alcoholism. Participants who interacted with loved ones less than once a month had a greater risk of developing the disease, and it was also affected by a lack of vitamin D.

The scientists’ findings indicate that early-onset dementia has modifiable risk factors that can be influenced by developing special preventive programs.
