Characterizing plausible causal pathways between COVID-19 reinfections and symptom ...
COVID-19 reinfections are prevalent, necessitating an urgent understanding of their cumulative, long-term impact in highly vulnerable populations. Evidence suggests that reinfections are associated with worse health outcomes; causal artificial intelligence (AI) modeling may provide additional insights. Using longitudinal symptom, biometric, and exertion data from 1,167 people with Long COVID and/or myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) in the Visible app, we investigated how cumulative COVID-19 infections may influence symptom trajectories. We evaluated five causal discovery algorithms with Non-combinatorial Optimization via Trace Exponential and Augmented lagRangian for Structure learning (NOTEARS) nonlinear emerging as optimal, showing strong predictive performance and structural validity. To evaluate pathways, we estimated interventional effects using the fitted structural causal model. Within our structural causal framework, our analysis suggests a 1.5% increase in post-infection symptom severity density and 4.9% increase in acute resting heart rate (RHR) across infections one to six. We estimate that pre-infection functional capacity (FUNCAP) may reduce post-infection symptom severity and symptom frequency by 27% and 21%, respectively, while pre-infection crashes may increase symptom severity by 8%. Due to symptom tracking requirements, this cohort was subject to a healthy user survivor bias, potentially underestimating true effects. These results indicate that reinfection count may exert measurable effects...

Large-scale whole-genome sequencing reveals the landscape and health implications of de novo mutations
We performed WGS of 8,328 live-born infants from 7,851 completed parent−offspring families after quality control (Fig. 2), including 7,374 singleton and 477 twin pregnancies, yielding 24,030 analyzed samples. Among these families, 5,619 conceived naturally (NC) and 2,232 conceived through ART (Extended Data Table 1). We identified 390,924 high-quality autosomal dnSNVs and 28,032 de novo indels (dnIndels), corresponding to an average mutation rate of 1.14 × 10−8 per nucleotide per generation, within the estimated ranges between 1.00 × 10−8 and 1.29 × 10−8 from previous WGS studies4,7,15,18. Of these, 42,811 (10.22%; 39,330 dnSNVs and 3,481 dnIndels) with variant allele frequencies (VAFs) below 0.35 were classified as EPZMs. For the remaining 376,145 DNMs, parent of origin was determined for 39.18% DNMs (147,372), yielding 112,037 (29.79%; 104,954 dnSNVs and 7,083 dnIndels) paternal and 35,335 (9.39%; 33,040 dnSNVs and 2,295 dnIndels) maternal DNMs. In subsequent analyses, DNM counts were standardized by callable region size, resulting in an average standardized DNM count of 61.61 per offspring. Consistent with previous studies4,19,20, maternal dnSNVs showed enrichment of C > T transitions at non-CpG sites, whereas paternal dnSNVs were enriched for T > G, C > A, C > G and C > T substitutions at CpG sites...

You can't give a cockatoo a face mask. There's only one way to fight bird flu
Opinion You can’t give a cockatoo a face mask. There’s only one way to fight bird flu Stephen LightfootConsultant anaesthetist August 7, 2026 — 3:30pm August 7, 2026 — 3:30pm You have reached your maximum number of saved items. Remove items from your saved list to add more. How does one prepare Australian birds for the arrival of the deadly H5N1 avian influenza virus – a virus with no treatment and no cure? Has Environment Minister Murray Watt spent the past few years handing out P2 face masks to cockatoos and teaching eastern rosellas the finer points of social distancing? As absurd as that sounds, that’s the impression one gets from the federal government as it becomes clear that bird flu has established itself in native bird populations in South Australia. “Don’t panic,” they say, “we’ve been preparing for years.” But a quick look at the government’s bird flu preparation shows how woefully prepared we are to protect our wildlife from this virus. The H5N1 virus is deadly. Not to humans but to birds and animals the world over. Recently, on the remote Heard and McDonald Islands, over 13,000 elephant seal pups died after the virus swept through breeding colonies...

Some COVID-19 Patients Suffered Heart Damage, an Overlooked Coronavirus Protein May Explain Why
When the COVID-19 pandemic started in 2020, leading to the largest, fastest, and most successful global development of a vaccine, researchers focused on the surface spike protein of SARS-CoV-2. This protein allows the virus to enter human cells, and because it sticks out all over the virus's outer shell, it makes the perfect target for a vaccine. But the spike protein isn't the only one that helps maintain the virus's function. By taking a closer look at the previously unrecognized role of the SARS-CoV-2 nucleocapsid protein, researchers from the University of California, Los Angeles (UCLA) found that it can hyperactivate the immune system in ways that may explain severe cases of COVID-19. In their study, published in Science Advances, they compared SARS-CoV-2's version of the nucleocapsid protein to those of other coronaviruses, like SARS and MERS, hoping to understand how to better tackle future virus outbreaks. “Coronaviruses are notorious for encoding proteins that antagonize the body's natural antiviral defenses,” said study lead Melody Li, an associate professor of microbiology, immunology, and molecular genetics at UCLA, in a news release. “When SARS-CoV-2 first appeared, almost nothing was known about it, so we wanted to find out whether it was using the...

Coronavirus disease 2019
COVID-19 is a contagious disease caused by the coronavirus SARS-CoV-2. In January 2020, the disease spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 can vary but often include fever,[7] fatigue, cough, breathing difficulties, loss of smell, and loss of taste.[8][9][10] Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms.[11][12] Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock, or multiorgan dysfunction).[13] Older people have a higher risk of developing severe symptoms. Some complications result in death. Some people continue to experience a range of effects (long COVID) for months or years after infection, and damage to organs has been observed.[14] Multi-year studies on the long-term effects are ongoing.[15] COVID‑19 transmission occurs when infectious particles are breathed in or come into contact with the eyes, nose, or mouth. The risk is highest when people are in close proximity, but small airborne particles containing the...
