NewsHeatproof microbes reveal molecular secrets of nature’s hottest recycling system
This study reveals how thermophilic bacterial communities withstand temperatures of up to 87°C by remodeling their molecular machinery. Scientists uncovered a heat-defense network centered on heat shock proteins that refold damaged enzymes and preserve protein structure.

NewsHidden HPV-linked cell type may drive early cervical cancer, scientists report
A new study identifies tumor-promoting keratinocytes linked to HPV infection and poor prognosis. Scientists employed single-cell RNA sequencing (scRNA-seq) and multiplex immunohistochemistry (mIHC) to delineate the molecular landscape of early-stage CESC.

NewsNewly discovered host mechanism in coronaviruses
A previously unknown cellular mechanism crucial to the replication of coronaviruses has been identified: c-Jun N-terminal kinase (JNK) is activated during infection with human coronavirus HCoV-229E and mediates the phosphorylation of the viral nucleocapsid (N) protein.

NewsFirst detection of zoonotic Rickettsia species in dog ticks from Malawi reveals potential public health risk
An international research team has reported the first molecular detection of Rickettsia bacteria in ticks collected from domestic dogs in Malawi, addressing a significant knowledge gap in understanding tick-borne disease risks in southeastern Africa.

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.

NewsNew study shows invasive Group A Streptococcus outcomes shaped by treatment strategies, not species lineage
Researchers highlight the role of early clindamycin prescription in improving the recovery rate of patients with invasive Group A Streptococcus infections in a study that examined the evolving epidemiology of such infections.

NewsEvolving antibiotic resistance under pressure may lead to personalized treatment
A new study demonstrates the use of an experimental evolution approach to map genetic mutations in Acinetobacter baumannii treated with one of two uncommon antibiotics.

NewsLow-dose cannabis compound reduces side effects of HIV treatment
Long-term, low doses of THC mitigate many harmful side effects and inflammation caused by HIV and antiretroviral therapy (ART). Benefits included increased production of serotonin, while inflammation, cholesterol and harmful secondary bile acids were all reduced.

NewsNew nasal vaccine has potential to transform respiratory disease prevention
Researchers have demonstrated that their nasally-delivered, antibiotic-inactivated Bordetella pertussis (AIBP) vaccine not only prevents severe disease but also curbs bacterial transmission — an achievement long sought by vaccine developers worldwide.

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.

News Sea stars show surprising resilience after disease outbreak
A decade after sea star wasting disease devastated ochre sea star populations along the U.S. West Coast, new research suggests that the epidemic shifted populations from a stable, adult-dominated state to one marked by fluctuations in sea star sizes and ages.

NewsMicroalgal-bacterial sludge offers sustainable solution for removing hormonal pollutants from wastewater
A team of researchers have revealed how microalgal-bacterial granular sludge (MBGS) can adapt and efficiently degrade estriol, a common endocrine-disrupting compound (EDC), under environmentally relevant conditions.

NewsBiochemists search for cellular vulnerabilities in killer ‘superbugs’
Helen Zgurskaya and Valentin Rybenkov are leading a five-year, $5.3 million project funded by the National Institute of Allergy and Infectious Diseases to find new ways to deliver lifesaving drugs directly into resistant pathogens.
-
NewsRODIN project will invest 10 M€ to explore cells as the architects of future biomaterials
RODIN - Cell-mediated Sculptable Living Platforms - is set to revolutionize the field of biomaterials and tissue engineering by shifting the focus from designing materials for cells to empowering cells to design their own environments.

NewsThe ‘MDME Axis’: A new view on how microbial metabolites epigenetically shape host health
A review introduces the ’MDME Axis’, a new framework explaining how metabolites from the gut microbiome epigenetically reprogram our genes, influencing host health and disease.
-
NewsResearchers discover novel phage DNA modifications that offer new hope against antibiotic-resistant superbugs
A groundbreaking discovery reveals a unique way phages modify their DNA with arabinose sugars to protect themselves from bacterial defence systems. Natural DNA phage modifications occur at a higher rate than previously predicted, the study revealed.

NewsMicrobiome around Xanthomonas infection in tomato plants signposts scientists to the bacterium of its downfall
Scientists have uncovered a bacterium in the microbiome of tomato leaves that can be used to fight back against infection by Xanthomonas, a disease that poses a major challenge to tomato growers worldwide.

NewsTemporary benefit for immune system in early HIV treatment, but dysregulation returns
A study investigated whether immune dysregulation can be prevented by starting HIV medication immediately after infection. Six months after this early treatment, the immune system did indeed work as in people without HIV, but in the longer term, the immune system was disrupted again.

NewsThe fart factor: researchers get wind of hydrogen’s role in the gut
Scientists have revealed how hydrogen is made and used in the human gut. Though infamous for making farts ignite, hydrogen also has a positive role supporting gut health.
