Walkable communities lowered mental health stressors during COVID-19 pandemic

University of New Hampshire
Peer-Reviewed Publication

Research out of the University of New Hampshire shows that communities that were easier for people to lace up and get out for a walk during the COVID-19 pandemic also helped lower the impact of mental health issues, like stress and anxiety.

Access to green space was a mental health lifeline during COVID-19 pandemic

University of Toronto
Peer-Reviewed Publication

A new national study led by researchers from Carleton University and the University of Toronto reveals that older adults living in greener neighborhoods were less likely to experience depression during the early months of the COVID-19 pandemic.

Exploring the therapeutic potential of pyridazinone derivatives: A comprehensive review

FAR Publishing Limited
Peer-Reviewed Publication

A recent review published in Current Pharmaceutical Analysis provides an in-depth look at the design, synthesis, and therapeutic potential of pyridazinone-based compounds. These derivatives have shown broad biological activities, including anticancer, anti-inflammatory, and antimicrobial properties. The study highlights recent advances and future directions in this promising field.

Patients with Long COVID forced to become their own doctors

University of Surrey
Peer-Reviewed Publication

An inability to get the support they need from medical professionals is forcing Long COVID sufferers to navigate and self-manage their illness using digital self-tracking tools and online support groups, according to a new study from the University of Surrey.

Vaccines trigger rapid lymph node responses

University of Turku
Peer-Reviewed Publication

Vaccines trigger a notably rapid response in the stromal cells of draining lymph nodes within the first hours after administration. Researchers at the University of Turku and the InFLAMES Flagship in Finland also discovered that the stromal alterations prime the lymph node landscape for the subsequent steps of vaccine-induced immune responses.

Covid infection ages blood vessels, especially in women

European Society of Cardiology
Peer-Reviewed Publication

A Covid infection, particularly in women, may lead to blood vessels aging around five years, according to research published in the European Heart Journal [1]. Blood vessels gradually become stiffer with age, but the new study suggests that Covid could accelerate this process. Researchers say this is important since people with stiffer blood vessels face a higher risk of cardiovascular disease, including stroke and heart attack.

COVID-19 linked to increased asthma risk – vaccine offers protection

Karolinska Institutet
Peer-Reviewed Publication

People who have had COVID-19 are at increased risk of developing certain inflammatory diseases of the airways, such as asthma, hay fever and chronic sinusitis. However, vaccination against the SARS-CoV-2 virus appears to reduce the risk, according to a comprehensive epidemiological study led by researchers at Karolinska Institutet.

Broad COVID-19 vaccination makes economic sense, especially for older adults, study finds

Michigan Medicine - University of Michigan
Peer-Reviewed Publication

As the nation gears up for the rollout of an updated COVID-19 vaccine, a new study shows the economic benefits of continued broad vaccination in adults. In fact, the country would ultimately save more money that it would spend on vaccinating every person over age 65 with a single dose of an updated mRNA vaccine against coronavirus, the study concludes.

Parents may have been more likely to cheat than non-parents during the COVID-19 pandemic

PLOS
Peer-Reviewed Publication

In a survey study of more than 1,000 U.S. adults who were in committed, heterosexual relationships during the first year of the COVID-19 pandemic, parents were more likely than non-parents to report an increased desire for infidelity since before the pandemic, and were also more likely to report having actually cheated on their partner during the pandemic. Dr. Jessica T. Campbell of Indiana University Bloomington, U.S., and colleagues present these findings in the open-access journal PLOS One on August 13, 2025.

Can officials say what they need to say about a health emergency in 280 characters?

Texas A&M University
Peer-Reviewed Publication

Public health officials had an unprecedented tool for near-instant, widespread communication during the COVID-19 pandemic and mpox epidemic: social media.

Now, one of the first studies of its kind, led by a health policy expert with the Texas A&M University School of Public Health, has found that X (Twitter at the time of the events) brought advantages — as well as disadvantages — in getting the word out.

Insilico employs AI-driven tools to uncover the link between idiopathic pulmonary fibrosis (IPF) and accelerated aging

InSilico Medicine
Peer-Reviewed Publication

Key Findings:

AI-powered Aging Clock: The new proteomic clock predicts biological age with high accuracy (R²=0.84, MAE=2.68 years) and captures accelerated aging signatures in severe lung disease cases—patients with severe COVID-19 (and likely fibrosis) exhibited biological ages nearly three years older than healthy controls.

Distinct Molecular Signatures: Analysis with the ipf-P3GPT generative model revealed both shared and unique gene expression patterns between aging lungs and fibrotic disease, highlighting that IPF is not just accelerated aging but entails unique pathological processes.

Pathway-Level Insights: The study identified four key pathways (TGF-ß signaling, oxidative stress, inflammation, ECM remodeling) as central to both IPF and aging, but involved differently at the gene level.

Fast, accurate, low-cost diagnostics: No lab required

Arizona State University
Peer-Reviewed Publication

Researchers at Arizona State University have developed a breakthrough diagnostic tool that could transform how quickly and reliably we detect illnesses like COVID-19, Ebola, AIDS or Lyme disease. The test uses just a single drop of blood, costs a couple of dollars and delivers results in only 15 minutes.

Study: Long COVID remains a substantial financial and medical burden

Rush University Medical Center
Peer-Reviewed Publication

Rush University Medical Center researchers who for years have been refining the clinical understanding of Long Covid (defined as persistent symptoms for more than three months) today shared findings showing that people experiencing those persistent symptoms also incurred more medical expenses and work-related issues than those who recovered more quickly from Covid-19. Detailed survey responses since early in the pandemic from more than 3,600 participants in the INSPIRE Covid-19 patient registry also suggests that getting vaccinated against Covid-19 is associated with better work and financial outcome whether people had Long Covid or not

What exactly is Long COVID? New UCLA research shows the answer depends on whom you ask

University of California - Los Angeles Health Sciences
Peer-Reviewed Publication

The definition of Long COVID varies so widely across published studies that the percentage of people identified as having the condition can differ dramatically, making it harder to treat patients and advance research.
