NewsBroad-spectrum coronavirus drug developed through AI-enabled dynamic modeling
Multidisciplinary AI- and physics-driven modeling of the viral fusion process enables discovery of an orally available drug inhibiting infection with multiple coronaviruses.

NewsScientists discover the ‘ticking’ mechanism driving nature’s simplest circadian clock
Researchers have uncovered the molecular mechanism that drives the ’ticking’ of the circadian clock in cyanobacteria. A clock protein called KaiC controls chemical reactions with precision, acting like the hand of a clock that waits, then moves at just the right moment.

NewsResearchers discover protein necessary for SARS-CoV-2 to evade the body’s defenses
Researchers have identified a protein that plays a key role in helping SARS-CoV-2 hide from the body’s defenses by suppressing the production of viral double-stranded (dsRNA), leading to increased viral replication while limiting the body’s immune response.

NewsNorthward jet stream shift hits phytoplankton in the Mediterranean Sea
In just over 20 years, the northward shift of the subtropical jet stream — a high-altitude airflow — caused by climate change has reduced primary production in the northwestern Mediterranean by about 40%, affecting the base of the marine food web.

NewsEvolutionary model for antibiotic resistance reveals dose timing critical to care
The study that uses a “fitness seascape” to incorporate a patient’s dosage schedule into models that predict whether an infection will develop antibiotic resistance has found that inconsistent timing and missing early doses can lead to treatment failure.

NewsMicrobiome stability shapes how corals withstand extreme heat
A new study reveals why some corals resist bleaching while others don’t: the answer lies in a complex partnership between corals and their microbial allies, shaped by the history of the waters they inhabit.

NewsOxymatrine, a quinoline alkaloid derived from Sophora flavescens, inhibits the Malassezia biofilm
Oxymatrine not only controls Malassezia overgrowth but also manages psoriasis symptoms, offering a dual-action mechanism for safer and more effective therapy, a new study shows.

NewsScientists develop a treatment platform to disable the ‘biofilm’ shield of superbugs
Researchers have developed a platform that utilizes microbubbles to deliver gene-targeted nanoparticles capable of breaking down MRSA biofilms, offering an innovative solution for treating infections resistant to conventional antibiotics.

NewsResearchers identify new llama-derived antibodies against current and future coronaviruses
Scientists have discovered a unique class of small antibodies that are strongly protective against a wide range of SARS coronaviruses, including SARS-CoV-1 and numerous early and recent SARS-CoV-2 variants.

NewsFusobacterium nucleatum in colorectal cancer: Ally mechanism and targeted therapy strategies
A recent review systematically outlines the pathogenic mechanisms of Fusobacterium nucleatum in colorectal cancer and summarizes both current and emerging strategies for its therapeutic targeting.

NewsGeneXpert MTB/RIF technology can distinguish non-tuberculous mycobacterial infection
Xpert Mycobacterium tuberculosis/rifampicin (Xpert MTB/RIF) in alveolar lavage fluid can not only detect rifampicin resistance but also distinguish pulmonary tuberculosis (TB) from non-tuberculosis mycobacterial (NTM) pulmonary disease.

NewsEpidemiological trends and serological profiles of respiratory pathogens in Guangzhou
A new study analyzing the epidemiological trends of multiple respiratory pathogens in Guangzhou, China, from 2013 to 2023, indicates the need for age- and gender-specific approaches to infection prevention and management.

NewsVaccinated patients hospitalized with COVID-linked acute kidney injury less likely to need dialysis after discharge
Vaccinated patients hospitalized with COVID-19 who developed acute kidney injury had better outcomes than unvaccinated patients with the same condition, new research suggests. The study found vaccinated patients were less likely to stay on dialysis after discharge, and more likely to survive, than unvaccinated patients.

NewsWhen bacteria get hungry, they kill – and eat – their neighbors
Scientists have discovered a gruesome microbial survival strategy: when food is scarce, some bacteria kill and consume their neighbors. The researchers show that under nutrient-limited conditions, bacteria use a specialized weapon — the Type VI Secretion System (T6SS) — to attack, kill, and slowly absorb nutrients from other bacterial cells.

News Ribosome profiling identifies thousands of new viral protein-coding sequences
With the help of a technique called Massively Parallel Ribosome Profiling (MPRP), scientists have identified more than 4000 open reading frames (ORFs) across 679 human-associated viral genomes.

NewsAn oral cholera vaccination campaign aims to reach more than 2.6 million people in Sudan’s Khartoum State
A 10-day reactive oral cholera vaccination campaign, launched on 10 June in 5 localities in Sudan’s Khartoum State, aims to protect more than 2.6 million people aged 1 year and above from cholera infection, interrupt transmission and help contain the cholera outbreak.

News2 million Americans with hepatitis C at risk if Supreme Court cancels free preventative care, study finds
A ruling overturning the Affordable Care Act (ACA) coverage mandate has the potential to dramatically change the landscape for early detection and treatment of hepatitis C virus in the U.S., according to a new paper.

NewsA combination of exercise and omega-3 reduces the severity of tooth root infections
Rats that exercised and took fatty acid supplements responded better to bacteria and the inflammatory process of apical periodontitis, which can occur when caries reach the root canal and cause an infection.

NewsIs your gut microbiome a calorie ‘super harvester’?
A little-known microbe makes methane in your gut — and may help you get more calories from food, according to a new study. Researchers found that people whose gut microbiomes produce a lot of methane are especially good at unlocking extra energy from a high-fiber diet.

NewsPeople with inflammatory RMD tolerate zoster vaccine well, study finds
New work presented at the 2025 annual EULAR congress in Barcelona focuses on the recombinant zoster vaccine (RZV), which contains recombinant glycoprotein E – the major target of CD4+T-cells. The abstract describes the tolerability and safety of RZV in patients with inflammatory rheumatic and musculoskeletal diseases (iRMD).
