Despite a less severe spread of the disease compared to 2024💥💥

An outbreak of avian influenza has led to the decision to cull over 1.3 million chickens on an Ohio farm, according to The Associated Press. The US Department of Agriculture announced on Tuesday that the flock is being slaughtered following the detection of a case of bird flu at the Union County egg farm. Despite a less severe spread of the disease compared to 2022, 8.1 million birds have been culled on commercial poultry farms this year, with 5.8 million birds in Ohio being among those culled this month, as reported by the AP.

This marks the second instance this month of a farm culling over 1 million birds, with a Taylor County,

 Iowa egg farm culling 1.1 million birds and a Wright County, Minnesota farm culling 940,000 birds.

Human cases of the disease remain rare, with only one reported case of a person contracting the H5N1

 strain of the virus in the U.S. since 2022, according to the CDC.

In related news, scientists have demonstrated how CRISPR gene editing can be used to combat bird flu.

What is bird flu?

Bird flu is a disease caused by a family of flu viruses primarily transmitted between birds.

According to the CDC and USDA, avian influenza viruses are classified into two groups:

1. Low Pathogenic Avian Influenza (LPAI) - often seen in wild birds

2. Highly Pathogenic Avian Influenza (HPAI) - found mostly in domestic poultry

The CDC states that LPAI viruses cause mild or no disease, while HPAI viruses cause severe disease and high mortality rates in infected birds.

The economic impact of bird flu has been significant, with the government spending roughly $660 million to manage the outbreak and poultry prices experiencing an increase.

At least 65 million birds have been culled since 2022 to limit the spread of the virus.

What are the signs of bird flu?

Signs that a bird may be infected with avian influenza include:

- Loss of appetite and lethargy

- Sudden death without prior symptoms

- Eyelid swelling

- Twisting of the head and neck

- Purple discoloration on body parts including the wattle and legs

- Stumbling and falling

- Diarrhea

- Difficulty breathing

- Nasal discharge

An Ohio farm is culling over 1.3 million chickens in response to an outbreak of avian influenza,

as initially reported by The Associated Press. The US Department of Agriculture announced on Tuesday

 that the flock is being euthanized following the detection of a case of bird flu on the Union County egg farm.Despite a milder impact compared to the previous year, the spread of the disease has resulted in the culling of 8.1 million birds on commercial poultry farms this year, with 5.8 million of them in Ohio alone,as reported by the AP. This marks the second instance this month of a farm culling over 1 million birds, with a Taylor County, Iowa egg farm and a Wright County, 

Minnesota farm also being affected.

Human cases of the disease remain infrequent, with only one reported case of a person contracting the H5N1 strain of the virus in the US since 2022, according to the CDC.

Additionally, scientists are exploring the use of CRISPR gene editing to combat bird flu, aiming to develop super-chickens resistant to the virus. Avian influenza, or bird flu, is caused by a family of flu viruses primarily transmitted among birds.

 According to the CDC and USDA, avian influenza viruses are categorized into Low Pathogenic Avian Influenza 

(LPAI) commonly found in wild birds, and Highly Pathogenic Avian Influenza (HPAI) prevalent in domestic poultry.These viruses cause varying degrees of disease in birds, with LPAI resulting in mild or no symptoms and HPAI causing severe disease and high mortality rates. The economic impact of the bird flu has been substantial,costing the government approximately $660 million and leading to increased prices of eggs and poultry. To curb the virus's spread, at least 65 million birds have been culled since 2022.Signs of avian influenza in birds include loss of appetite, lethargy, sudden death without prior symptoms, eyelid swelling, twisting of the head and neck, purple discoloration of body parts, stumbling and falling, diarrhea, difficulty breathing, and nasal discharge.

Consuming a reduced number of calories may help stave off the effects of aging.

 Consuming a reduced number of calories may help stave off the effects of aging.🥣🙅

In 1991, a group of eight volunteers sealed themselves inside a large greenhouse in the desert near Tucson, Arizona as part of an experiment known as "Biosphere 2". This experiment aimed to determine if a carefully chosen assortment of plants and animals could form a self-sustaining ecosystem independent of the outside world. While the Biosphere 2 experiments did not yield significant ecological insights, they did shed light on the potential effects of calorie restriction on human aging.

One of the participants in the Biosphere 2 project was Roy Walford, a professor at the University of California, Los Angeles. Walford's prior research had demonstrated that restricting the diets of various animals could remarkably extend their lifespans. Notably, laboratory protocols involving reduced calorie intake while maintaining necessary nutrients had lengthened the lives of nematode worms, fruit flies, rodents, and dogs by up to 50%.

The Biosphere 2 experiment provided Walford an opportunity to test this theory on humans within a confined environment. 

With a daily calorie intake of 1,750-2,100, the participants, already lean, experienced weight loss and sustained high energy levels. Furthermore, blood tests revealed physiological responses resembling those of calorie-restricted animals with extended lifespans.

While some individuals have considered incorporating calorie restriction into their lifestyles based on these findings, maintaining such diets proves challenging.

 Consequently

 there is a growing interest in discovering methods to obtain the benefits of calorie restriction without adhering to strict dietary limitations.

Calories represent the energy cells derive from breaking down food, a process regulated by various signaling pathways. Dysfunction in these nutrient-signaling pathways is recognized as one of the hallmarks of aging. The success of calorie restriction suggests that when energy is limited, cells' nutrient-signaling pathways maintain cellular health more effectively. Finding alternative cues to activate these pathways without reducing calorie intake is crucial in understanding the potential benefits of calorie restriction without its associated challenges.

Research into these pathways would be more straightforward if their functions were distinct and well-defined. Unfortunately, this is not the case, as pathways frequently regulate multiple functions and are controlled by various proteins with complex names. For instance, the MTORC1 pathway, which regulates metabolism in response to nutrient availability and use impediments, is influenced by the immune suppressant rapamycin, despite its name providing little insight into its broader functions.

Moreover, rapamycin has been linked to longevity in lab animals, despite its immune-suppressing effects, prompting some to seek off-label prescriptions for it. However, its side effects, such as anaemia and insulin insensitivity, limit its widespread use.
