Lab-grown meat could be the future of food — but possibly not in our lifetimes: experts

The Current24:29Will lab-grown meat ever reach our plates?Read transcribed audio.What's cultivated, meat-like, and could help lower greenhouse gas emissions? Lab-grown meat — and it could be the future of protein.Sometimes known as cultured meat, lab-grown meat is unlike plant-based alternatives from companies such as Beyond Meat or Impossible Foods. Instead, it's made by taking a few stem cells from an animal's muscle, then placing them in a nutrient broth where they multiply and are triggered to turn into muscle…

Nanoparticles Repair Lung Tissue Damaged From Flu or COVID-19

Confocal imaging demonstrating the dense network of capillary blood vessels in the lung that allow oxygen to move into our bloodstream. This complex vascular network can be severely disrupted upon viral infections like influenza and COVID-19, which greatly contributes to disease severity and mortality. Credit: Gan ZhaoRecent research reveals a breakthrough in lung repair, showing how delivering VEGFA via lipid nanoparticles can significantly repair damaged blood vessels, akin to plumbing repairs. This method, validated in…

Born in October? You’re Less Likely To Catch the Flu, According to a New Study

A study published in The BMJ finds that October-born children have higher flu vaccination rates and lower flu diagnosis rates, underscoring October as the optimal month for vaccinating young children against influenza, in line with existing health recommendations.A new study indicates that October is the best time for young children to have annual flu shot.A study recently published in The BMJ reveals that children born in October have a higher likelihood of receiving influenza vaccinations and a lower likelihood of being…

Scientists Propose New Way To Prevent Spread of Flu

Recent research demonstrates that blocking the attachment of virus particles to cell surface molecules in infant mice can significantly reduce the transmission of influenza A. This finding opens the door to new preventative strategies against seasonal flu, potentially supplementing existing vaccines and treatments with methods that target the host’s ability to spread the virus.Researchers have long understood that certain viruses and bacteria initiate infections by initially attaching to sugar molecules present on the…

Gut Bacteria’s Surprising Role in Combating Flu and COVID-19

Research from Georgia State University shows that gut bacteria, particularly segmented filamentous bacteria, play a crucial role in protecting mice against respiratory viruses by influencing immune cells in the lungs. This study could have profound implications for understanding and managing respiratory infections in humans.Researchers at the Center for Translational Antiviral Research within the Institute for Biomedical Sciences at Georgia State University have discovered that the makeup of gut microbiota affects mice’s…

Scientists Discover New Class of Antibodies That Could Neutralize the Flu Virus

Researchers have discovered a new class of antibodies capable of neutralizing various flu virus strains, potentially aiding in the development of more broadly protective flu vaccines. This breakthrough, to be published in PLOS Biology, emphasizes the importance of diversifying flu vaccine production methods and provides new avenues for vaccine design.The findings may assist in creating vaccines that offer wider protection against various flu strains.Researchers led by Holly Simmons from the University of Pittsburgh School…

Bird Flu Has Made a Terrifying Leap That’s Devastated Argentina’s Seal Populations : ScienceAlert

Almost 96 percent of Southern elephant seal pups across Argentina born in 2023 have met a tragic end as a highly contagious strain of avian influenza continues to wreak havoc on wildlife.The scale of mortality sparks concerns that the H5N1 strain is now capable of mammal-to-mammal infection."The sight of elephant seals found dead or dying along the breeding beaches can only be described as apocalyptic," says Wildlife Conservation Society (WCS) health director Chris Walzer.The three beaches where the species breeds were…

Bird Flu Kills a Polar Bear in a World First. Here’s What That Means For Us. : ScienceAlert

Climate change is a threat to polar bear's survival. Now they have a new deadly challenge facing them: bird flu. It was recently confirmed that a polar bear from northern Alaska has died from the disease.The current strain of H5N1 influenza has affected a far wider range of species than any previously recorded strain. This has included several mammal species, such as foxes, otters, mink, sea lions and seals (including, for the first time, seals in Antarctica).Cases have been detected in humans, too.However, while some…

There’s a Huge Covid Surge Right Now and Nobody Is Talking About It

Since 2021, all dominant Covid variants have descended from Omicron. The 2023–2024 booster was tailored for the XBB.1.5 strain of Omicron, but JN.1 is about as different from XBB.1.5 as Omicron was from Delta. Even so, researchers from China and the US have posted preliminary analyses suggesting that the newest vaccines still effectively defend against JN.1.That is, if people keep up with their vaccinations—and most haven’t. Over 80 percent of people in the US have not yet received the updated 2023–2024 booster shot, the…

The Rise of “Long Flu” – A New Health Challenge Similar to Long COVID

By Washington University in St. Louis December 31, 2023A study comparing COVID-19 and seasonal influenza shows both viruses can cause significant long-term health issues post-hospitalization, with COVID-19 affecting multiple organ systems and the flu mainly impacting the respiratory system. Study shows patients hospitalized for flu or COVID-19 face increased risk of long-term health problems and death.Since the COVID-19 pandemic began, extensive research has emerged detailing the virus’s ability to attack multiple organ…
