NewsResearchers aim to improve access to high-quality research and biomanufacturing tools in resource-limited settings
Researchers have demonstrated the effectiveness of a suite of low-cost, portable biotechnology tools designed to improve access to laboratory research and diagnostics in resource-limited settings.

NewsScientists validate a link between autoimmunity in a subset of people with long COVID
A research team has demonstrated that autoimmunity, where the body’s immune system attacks its own tissues, is responsible for the often-debilitating and confounding symptoms of long COVID in a subset of people.

NewsLong Covid burden continues to grow, doubling current surveillance estimates, multi-hospital study shows
Investigators using a novel AI algorithm to comb through medical records of patients with COVID-19 in U.S. hospitals, found around one in six developed long COVID. These rates are twofold higher than current estimates.

NewsCommon illnesses, not hantavirus, pose greatest cruise and travel risk
Travelers booked on cruises this summer, or considering booking, shouldn’t change their plans out of fear of hantavirus, one researcher says. They should be aware of more common viral illnesses that occur in cruise settings such as norovirus, seasonal respiratory viruses, COVID-19 and influenza.

NewsHeart health may have impacted the risk of severe COVID-19 infection during the pandemic
Adults with highest heart health scores at the beginning of the pandemic were nearly half as likely to be hospitalized or die from COVID-19 when compared to those with the lowest scores, according to new research.

FeaturesEquity and the response to Covid 19 - Preparing for the next pandemic in Aotearoa New Zealand
Aotearoa New Zealand enacted an effective response to the Covid-19 pandemic. The government approach to the first few cases in March 2020 was to implement a swift ‘go hard and go early’ response. Borders were closed to non-residents, lockdowns were enforced, and infection was effectively eliminated within 76 days of ...

NewsNP14 aptamer: A novel biosensing recognition element for mutation-resilient SARS-CoV-2 detection
New research investigated a novel DNA aptamer, NP14, and developed an innovative dual-mode biosensing platform to achieve highly sensitive, mutation-resilient viral detection.

NewsNew immune system enhancer extends COVID-19 vaccine protection reducing need for repeated boosters
Researchers demonstrated that pairing the original COVID-19 mRNA vaccine with an adjuvant extended the duration of the vaccine’s protection in mice from a few months up to two years. The combo also showed a more pronounced response against omicron viral components than the vaccine alone.

NewsBrain inflammation is unlikely to explain persistent long COVID symptoms
A new brain imaging study has found no evidence of widespread brain inflammation in patients suffering from prolonged symptoms after COVID-19 infection. Instead, the most severe long COVID symptoms were associated with increased brain activity in regions involved in mood and emotion.

NewsPatent targets viruses with a breakthrough from linseed oil
A common vegetable oil may hold the key to fighting some of the world’s most dangerous viruses. Scientists have patented a linseed oil polyol-derived compound shown to inhibit viral infections including HIV and SARS-CoV-2 as well as bacterial infections causing strep and staph.

NewsHealthcare utilization disruptions continue in post-COVID China
Although China’s stringent public health policy, Dynamic Zero-Covid, was lifted in late 2022, researchers have discovered substantial, long-term declines in outpatient clinic visits and hospitalizations compared to expected levels from 2020 to 2024 in China.

NewsCOVID racism driven by more than fear of infection
Anti-Asian discrimination and violence increased during COVID, and new research has revealed one key psychological driver. Rather than being driven by a fear of infection, aggressive forms of discrimination appeared to be more strongly associated with anger.

NewsSweeping up dust to detect emerging viruses
Gathering dust from buildings may hold promise as a more efficient way to track viral outbreaks in indoor settings, according to a new study. After collecting nearly 30 vacuumed dust samples from different buildings, researchers simultaneously identified the presence of 54 distinct viruses.

NewsMeasuring SARS-CoV-2 diversity in wastewater improves disease surveillance
Tracking the genetic diversity of SARS-CoV-2 in wastewater, rather than just viral abundance, dramatically improves the ability to monitor and predict COVID-19 outbreaks, researchers report.

NewsIgG fucosylation linked to severe COVID-19 progression and traditional Chinese medicine therapy
A new study has uncovered that immunoglobulin G (IgG) fucosylation, a critical type of protein glycosylation, is closely associated with the progression of severe COVID-19, offering new insights into disease pathogenesis and potential therapeutic strategies.

NewsDiseases can spread between apartments via shared ventilation, study shows
Airborne diseases like measles, influenza and COVID-19 can easily spread between units in multi-family buildings via a type of bathroom ventilation system commonly used around the world, new research suggests.

NewsFlawed but correctable research hindered progress in infection-triggered chronic conditions
Researchers contend that studies of infection-associated chronic illnesses such as Lyme disease and COVID-19 suffer recurring problems such as the failure to prove participants have the relevant pathogen.

NewsStudy reveals common mutation linked to autoimmune diseases may protect people from viral infections
New research shows a “risk gene” linked to higher odds of developing autoimmune diseases such as diabetes or lupus may also provide a survival advantage fighting viral infections like coronavirus. The gene PTPN22 carries a mutation, 1858C>T (R620W), found in roughly one in 10 people in North America.

News‘Atomic snapshots’ of proofreading enzyme could lead to better COVID-19 drugs
A research team used images generated by a cryogenic electron microscope (cryo-EM) to observe the interplay between SARS-CoV-2 proofreading enzyme exoribonuclease (ExoN) and RNA incorporated with antivirals such as remdesivir, sofosbuvir and bemnifosbuvir.
