The US Centers for Disease Control and Prevention have completed a pandemic risk assessment of the H5N1 avian influenza virus that recently infected a dairy worker in Texas. Using their Influenza Risk Assessment Tool, the CDC determined that the virus poses a low risk to the general public, but a moderate risk in terms of potential pandemic spread. This virus is the third of its kind to receive a moderate risk assessment in recent years, and it scored higher on some risk elements but lower on others compared to previous strains. The Colorado Veterinary Medical Association has also issued a warning about the virus's potential impact on cats, even without traditional risk factors or symptoms present.
Avian Influenza and Cat Virus Disease: An Overview
Avian influenza, commonly known as bird flu, is a highly contagious viral disease that primarily affects birds. However, certain strains of the virus have been known to infect humans and other mammals, including cats.
Current Outbreak
In February 2023, the United States Centers for Disease Control and Prevention (CDC) completed a pandemic risk assessment of the H5N1 avian influenza virus that recently infected a dairy worker in Texas. The virus was determined to pose a low risk to the general public but a moderate risk in terms of potential pandemic spread.
Impact on Cats
The Colorado Veterinary Medical Association (CVMA) has also issued a warning about the virus's potential impact on cats, even without traditional risk factors or symptoms present. Cats can become infected with H5N1 through contact with infected birds, their droppings, or contaminated surfaces.
Background
Avian influenza has been a global concern for decades. The virus is constantly mutating, and new strains emerge periodically. Some strains are highly pathogenic, causing severe illness and death in birds.
In recent years, there have been several outbreaks of avian influenza in both poultry and wild birds. In 2023, the virus was detected in both commercial and backyard flocks across the United States.

Social media was abuzz with videos of a small asteroid burning up over the Philippines on Wednesday. Named 2024 RW1, the asteroid was discovered just hours before its impact by research technologist Jacqueline Fazekas. This highlights the need for space agencies to continue their efforts in tracking and cataloguing near-Earth objects through missions like NASA’s Double Asteroids Redirect Test.
This year marks the 42nd anniversary of National Nutrition Week, an annual observance in India that aims to educate and raise awareness about the importance of nutrition for overall health and well-being. The week-long event focuses on the link between nutrition and good health, and provides strategies to combat issues related to malnutrition. With a focus on promoting balanced meals and reducing consumption of processed foods, this initiative is a crucial step towards improving the health and well-being of individuals across all age groups.
As Jupiter and Saturn make their return to the September sky, they bring along their diverse and intriguing moons for stargazers to admire. With Saturn boasting a total of 146 identified moons, including the easily visible Titan and the erupting Enceladus, and Jupiter showcasing the mesmerizing Galilean Moons, this month's celestial event is a must-see for astronomy enthusiasts. These moons not only offer stunning views, but also hold potential for future exploration missions, such as NASA's Dragonfly mission to Titan in the 2030s.
A rare and fatal mosquito-borne virus, known as Triple E, has claimed its first victim in the US this year. The eastern equine encephalitis virus (EEEV) has been detected in multiple states, including a death in New Hampshire and four other cases. Scientists warn that the virus, which primarily affects the eastern and Gulf Coast states, is difficult to predict and can be deadly. Experts explain its origins, symptoms, and how it can potentially spread.
NVIDIA's highly anticipated B100 AI GPU faces significant setbacks as design flaws halt its production and prompt a replacement with lower cost and performance. The company admits to low yields and plans to re-spin the B200 tile to improve production and meet its Q4 2026 release. Analysts predict a 3-month delay and prioritize the revised B200A for hyperscalers, effectively scrapping the B100. With a passion for AI hardware, Anthony Garreffa from TweakTown predicts the impact of these developments on NVIDIA's profitability and reputation.
NASA has announced that astronauts Suni Williams and Butch Wilmore will have to remain on the International Space Station (ISS) until 2025 due to ongoing issues with the Boeing Starliner spacecraft. With the return journey postponed, NASA has turned to Elon Musk's SpaceX to bring the astronauts back to Earth. This delay highlights the importance of careful consideration and communication in the risky world of spaceflight.
NASA has announced that they have selected Elon Musk's SpaceX to bring astronauts Sunita Williams and Barry Wilmore back from the International Space Station (ISS) next year. Williams and Wilmore have been on the ISS for over 80 days and were originally scheduled to return with Boeing's Starliner, but due to technical issues, their stay is being extended and they will now be returning with SpaceX's Crew Dragon spacecraft. NASA Administrator Bill Nelson explained the decision was made for the safety of the astronauts, as the Starliner's propulsion system presented too much risk. The news has also sparked discussions about rebuilding trust in Boeing among NASA officials.
As global space agencies continue to make plans for colonizing Mars, scientists have identified a variety of materials that can serve as protection against hazardous cosmic radiation. This study, led by researchers from the University of Patras and NYU Abu Dhabi, evaluated different materials using computer modeling and actual data from NASA's Curiosity rover. The development has implications for the safety of astronauts on extended Mars missions, as the planet's arid and exposed environment poses a significant risk for prolonged human exposure to radiation.
