[music] Have a look at these pictures. I tried to reproduce famous drawings of humans and rabbits embryos uh drawn by heckle. Can you tell for sure which one is human and which one is rabbit.Probably no. I wouldn't if it was not me who drew the pictures. Why they so similar.And how can such different organisms like humans and rabbits developed from a nearly identical embryo. Think of it. These are limps.Humans and horses. They are different for sure and they serve different purposes. Human arms are good for ...
How persistent pathogens could accelerate the aging process | Amy Proal | TEDxBoston
TEDx Talks· 2025-11-21 17:02
Core Argument - The prevailing aging models inadequately address the role of persistent pathogens (viruses, bacteria, parasites) as a significant driver of human aging and healthspan reduction [1] - Persistent pathogens can embed themselves in tissues and nerves, potentially driving various health problems later in life [2][3][4] - These pathogens can actively distort the signaling of human genes, impacting multiple hallmarks of aging [8] Pathogen Prevalence and Impact - Approximately 95% of individuals harbor one or more strains of herpes virus [5] - Around 11% of people in the US and up to 87% in some global regions carry the chronic parasite toxoplasma [6] - Persistent SARS-CoV-2 virus has been found in tissue samples months or years after initial infection [7] - Pathogens can drive mitochondrial dysfunction by hijacking host cell metabolism [10][11][12] - Viruses can integrate into telomeres, leading to shorter and more unstable telomeres [13][14] - Viral proteins can interact with and distort the signaling of human aging pathways [15] Proposed Solutions and Recommendations - The industry needs to seriously consider the impact of persistent pathogens when developing healthspan extending interventions [17] - Curbing the activity of pathogens should precede interventions like gene editing [18] - Integrating existing antiviral and anti-parasite medications into healthspan protocols is recommended [18] - Individuals with herpes simplex virus who regularly took anti-herpes virus medications had a 10 times lower risk of developing dementia [19] - Investment in new diagnostic test platforms to identify persistent pathogens is crucial [20][21] - Incorporating the activity of persistent pathogens into aging models is essential for successfully extending healthspan [22]
‘Flesh-eating’ bacteria kills four people in Florida
NBC News· 2025-07-20 21:47
Health Risk Alert - Four deaths have occurred due to a rare flesh-eating bacteria found in warm coastal waters [1] - At least 11 individuals have contracted illness from vibrio vulnificus [1] - Infections from vibrio vulnificus can be severe and life-threatening for some individuals [1] Bacteria & Infection Details - Vibrio vulnificus spreads through raw seafood, mainly oysters, or open wounds in direct contact with seawater [1] - The infection can spread rapidly [2] Prevention Measures - Doctors recommend covering open wounds with bandages if exposed to seawater [2] - Thorough cleaning of cuts and scratches is advised after seawater exposure [2]

High bacteria levels force beach closures across the U.S.
NBC News· 2025-07-02 10:37
Beach Closures & Public Health Concerns - At least five states, including New York, California, Massachusetts, Michigan, Illinois, and Washington State, are tracking beach closures due to rising bacteria levels in the water [1] - Health officials are urging people not to enter the water at 17 beaches in the Chicago area [1] Bacteria & Infection Risks - There isn't one common cause across all regions; Washington State is dealing with toxic algae, while other areas are concerned about E coli [2] - Vibrio, a bacteria naturally occurring in coastal waters, is a concern due to potential spikes during extreme heat and heavy rain [2] - Infection can occur if swimmers swallow contaminated water or if water enters open wounds [2]
