NewsCOVID-19 leaves a lasting mark on the human brain
COVID-19 does not just affect the respiratory system, but also significantly alters the brain in people who have fully recovered from the infectious disease, highlighting the long-term neurological impact of the virus.

NewsWho is more likely to get long COVID?
Scientists have identified the key genetic drivers behind long COVID, revealing why some people continue to experience debilitating symptoms long after their initial infection.

NewsCOVID-19 vaccination significantly reduces risk to pregnant women and baby
Pregnant women who received a COVID-19 vaccine were far less likely to experience severe illness or deliver their babies prematurely, according to a major new study.

NewsCould hidden infections be fueling long COVID?
For millions suffering from long COVID, their persistent breathlessness, brain fog and fatigue remain a maddening mystery, but microbiologists think they may have cracked the case. The review argues that co-infections acquired before or during COVID could cause symptoms to persist indefinitely for many people.

NewsStudy shows why mRNA-based COVID-19 vaccines can cause myocarditis
Investigators have unearthed the biological process by which mRNA-based vaccines for COVID-19 can cause heart damage in some young men and adolescents — and they’ve shown a possible route to reducing its likelihood.

NewsOld molecules show promise for fighting resistant strains of COVID-19 virus
SARS‑CoV‑2 continues to mutate, with some newer strains becoming less responsive to current antiviral treatments like Paxlovid. Now, researchers have identified several promising molecules that could lead to new medications capable of combating these resistant variants.

NewsTo treat long COVID, we must learn from historical chronic illnesses, medical researchers say
Scientists and doctors have highlighted the importance of studying long COVID in the context of other post-acute infection syndromes or chronic illnesses. By analyzing historical accounts of other epidemics, researchers can gain important perspective on the effects of these chronic illnesses.

NewsThe immune system creates its own targets within viruses
A new study reveals that our immune system does more than defend against viruses. In certain cases, it induces mutations within viruses that make them easier to recognize later on.

OpinionWe couldn’t get people interested in science - until we started speaking their language
In 2020, Puerto Rico faced a misinformation crisis. Melanie Ortiz Alvarez De La Campa reveals how five STEM undergraduates created a sci-comm organization that helped pass legislation, educated thousands, and created an inclusive database of Caribbean scientists.

NewsScientists uncover how COVID-19 variants outsmart the immune system
Researchers have created the most comprehensive map to date showing how antibodies attach to the SARS-CoV-2 virus, which causes COVID-19, and how viral mutations weaken that attachment.

NewsDid US cities’ indoor vaccine mandates affect COVID-19 vaccination rates and outcomes?
New research reveals that despite widespread adoption of indoor vaccine mandates in major US cities during the COVID-19 pandemic, there is no consistent evidence that these policies significantly increased vaccination rates or reduced COVID-19–related outcomes. The findings contrast with those from other countries, as national mandates abroad boosted vaccine uptake.

NewsWomen are three times more likely than men to get severe long COVID: Here’s why
Researchers have identified a distinct immune signature in female long Covid patients versus male patients. They found evidence of ’gut leakiness’ in the women patients, including elevated blood levels of intestinal fatty acid binding protein, lipopolysaccharide, and the soluble protein CD14 — all signs of gut inflammation that can then trigger further systemic inflammation.

NewsHuman PARP gene could be novel target for viral diseases or immune-mediated disorders
Researchershave discovered a human gene, the protein PARP14, plays a role in regulating interferon, part of the body’s innate immune system. Their study could guide development of antiviral therapies for several groups of viral infection.

NewsCould tiny airborne plastics help viruses spread? Scientists warn of a hidden infection risk
While plastics are already recognized as a global environmental threat, a new commentary highlights that their microscopic airborne forms could also play a hidden role in human infection.
-
NewsNo-needle test can tell if flu/COVID vaccines are effective
A team of researchers has developed a skin patch that can detect antibodies associated with COVID and flu infections. It’s orders of magnitude more sensitive than existing tests, uses just a half volt of electricity, and can return results in 10 minutes.

NewsCOVID-19 vaccination lowers long COVID risk in adolescents
Adolescents who were vaccinated against COVID-19 were less likely to develop long COVID after their first SARS-CoV-2 infection than unvaccinated peers, finds a new study.

NewsERC Synergy Grant awarded to physicist Michael Lässig and virologist Florian Klein
Researchers have been awarded a Synergy Grant by the European Research Council (ERC) for the project CoEvolve, which investigates the co-evolution of viruses and the immune system.

NewsCOVID-19 vaccination linked to reduced infections in children with eczema
Children with atopic dermatitis (AD), commonly known as eczema, may experience fewer infections and allergic complications if they receive the COVID-19 vaccine, according to new research.
-
NewsResearch finds higher rare risk of heart complications in children after COVID-19 infection than after vaccination
A whole-population study showed that although these conditions were rare, children and young people were more likely to experience heart, vascular or inflammatory problems after a COVID-19 infection than after having the vaccine — and the risks after infection lasted much longer.

NewsCOVID-19 during pregnancy linked to higher risk of neurodevelopmental disorders in children
Children born to mothers who had COVID-19 while pregnant face an elevated risk of developmental disorders by the time they turn 3 years old, including speech delays, autism, motor disorders, and other developmental delays, according to new research.
