FeaturesClinical considerations for the next pandemic: challenges facing Japan and strategic preparedness
Multiple global pandemics over the past century – the Spanish influenza (1918), Asian influenza (1957), Hong Kong influenza (1968), H1N1 influenza (2009), and COVID‑19 (since 2019) – have increasingly underscored the necessity for healthcare systems worldwide to be resilient, rapidly responsive, and forward‑facing.

NewsA closer look at immune ‘memory’ - and how long it lasts
A new review shares recent advances from the field of immune memory and highlights key steps we might take to develop even more effective, longer-lasting immunity against deadly diseases.

NewsResearchers explore potential link between COVID-19 and lung cancer risk
New findings have identified a potential association between COVID-19 and increased lung cancer risk, driven by underlying biological mechanisms in the lung. The study integrates human clinical data with mechanistic research in animal and cellular models.

NewsLong COVID associated with increased risk of cardiovascular disease
People with long COVID are at increased risk of developing cardiovascular disease, according to a new study. Women with long COVID had just over twice the risk of receiving a cardiovascular diagnosis compared with women without long COVID. Men had approximately a third higher risk.

NewsNew vaccine strategy could help extend immunity against evolving viruses
Researchers have identified a possible way to make longer lasting vaccines for respiratory viruses like influenza and the coronavirus that causes COVID-19.

OpinionDisease X and the limits of voluntary multilateralism
Disease X is less a biological uncertainty than a governance stress test. The real question is whether the WHO Pandemic Agreement has corrected the failures exposed during COVID-19.

NewsAging lung cells could be why COVID and flu are so dangerous to the elderly
Older adults are much more likely to become seriously ill from flu or COVID because aging lung cells can drive excessive immune responses, according to a new study led by researchers.

FeaturesCan we make a vaccine against the next Disease X in 100 days?
The COVID-19 pandemic was one of the deadliest events in modern history. Estimated to have killed over 25 million people worldwide and caused trillions of dollars in economic damage, the devastation caused by this virus was both astronomical and unforgettable.

NewsGenetic breakthrough uncovers evolutionary limits of the COVID-19 virus
A new paper indicates that while the COVID-19 virus has developed rapidly since 2019, it has done so within limited genetic channels. These genetic limits have remained unchanged.

NewsAutoantibodies implicated as drivers of long COVID in new study
A new study shows that antibodies from Long COVID patients can induce persistent pain-like symptoms in mice. This provides evidence for a potential causal role of autoantibodies in Long Covid.
-
NewsStudy details neuropsychiatric symptoms and biological mechanisms of long COVID
A review highlights the need to standardize diagnosis and treatment of long Covid. In the study, the researchers emphasize that avoiding SARS-CoV-2 infection is the only way to prevent long COVID so far.

NewsNew study reveals spleen-to-lung neutrophil axis orchestrates antiviral defense
Single-cell spatial mapping uncovers the spleen as a critical reservoir for lung neutrophils during respiratory viral infection, according to a new study.

NewsNovel biosensing platform enables fingertip blood-based micro-volume t-cell immune monitoring
A new platform, known as Tip Optofluidic Immunoassay Interferon-Gamma Release Assay (TOI-IGRA), could revolutionize how people monitor their immune health. The platform allows for the precise quantification of pathogen-specific T-cell responses using a mere 15-25 μL of fingertip blood.

NewsInappropriate antibiotic use for COVID-19 is linked to resistance
Taking azithromycin for as little as one day triggers antibiotic resistance in the respiratory tract, according to a first-of-its kind look by scientists at the changes that occur in the microbiome of hospitalized patients who were treated for COVID-19.

NewsTrial finds vitamin D supplements don’t reduce Covid severity but could reduce long COVID risk
In a large, randomized trial, researchers have found that high-dose vitamin D3 did not reduce COVID-19 infection severity, but may impact long COVID outcomes.

NewsSevere COVID-19 and flu facilitate lung cancer months or years later, new research shows
Severe COVID-19 and influenza infections prime the lungs for cancer and can accelerate the disease’s development, but vaccination heads off those harmful effects, new research indicates.
-
NewsBuilding protection against infectious diseases with nanostructured vaccines
Researchers have leveraged a recently developed highly versatile DNA origami nanotechnology that is both vaccine and adjuvant, named DoriVac, as an alternative to current vaccine platforms.
-
NewsRecent pandemic viruses jumped to humans without prior adaptation, study finds
A large-scale evolutionary analysis shows most zoonotic viruses emerge without prior adaptation, while passing through a laboratory leaves detectable genetic signatures, offering a new tool to interpret outbreak origins.

News How viruses mess with our brains
What impact does a viral infection have on our memory, attention, and concentration? A new review has identified several biological markers associated with cognitive decline in the context of infection. It also provides a solid foundation for future research.

NewsStudy finds natural fungal supplement improves COVID-19 vaccine response
Researchers have found that a natural fungal supplement taken at the time of COVID-19 vaccination reduced short-term vaccine side effects and helped antibodies last longer in people who had not previously been exposed to the virus.
