NewsGenomic analysis redefines the origin of eukaryotic cells
A new genetics study using the MareNostrum supercomputer redefines the genetic origin of the last common ancestor of all eukaryotes, highlighting the contribution of novel bacteria and even giant viruses in the emergence of eukaryotic cells.

NewsAsk the expert: World Cup travel and Ebola risk
Luis Ostrosky, MD, division chief of infectious diseases at McGovern Medical School at UTHealth Houston and chief epidemiology officer for Memorial Hermann Health System addresses the Ebola outbreak in Congo and Uganda and how the United States could be affected through travel.

NewsAs California warms, cases of dengue fever are expected to grow
Historically, dengue fever has been rare in California. But according to new research, a warming climate is making parts of the state more hospitable to the illness — and the mosquitoes that carry it.

NewsScientists probe antiviral molecules in bacteria that target bacteriophages
Researchers have examined the antiviral molecule daunorubicin, produced by Streptomycetes, and decoded its mode of operation against viruses. They now describe this mechanism, which primarily targets a specific group of viruses – namely bacteriophages.

NewsBacteria organise themselves into diverse, coordinated communities in order to travel across large distances
A new study examined the migration of microbial communities over long distances, and found bacteria migrate not as solitary swimmers, but in diverse, coordinated communities that also contain viruses and “hitchhiking” microbes that cannot swim on their own.

NewsFirst-in-human clinical trial shows promising results for new Lassa fever vaccine
Researchers have reported encouraging results from an early clinical trial that tested a new dual vaccine against Lassa fever and rabies. The study found that the vaccine was safe and induced immune responses against both viruses. There are currently no vaccines against Lassa fever on the market.

NewsPlants could be used to grow medicines in space, study shows
Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand. Researchers developed a simple method to grow and repeatedly harvest plant virus-based pharmaceuticals from plants under space-like conditions, without destroying the plants or generating large amounts of waste.

NewsTesting AI against public health’s existing tools
A new study found that AI chatbots made vaccine-hesitant parents more likely to say they would vaccinate their children against HPV, but did not outperform materials from government health agencies, whose effects also lasted longer.

NewsAccelerating chikungunya vaccine development in Africa: Launch of the ACT-CHIK Project
Funded by the Global Health EDCTP3 Joint Undertaking, a new €15.3 million project coordinated by Institut Pasteur brings together seven partners across four continents to advance clinical trials and prepare for the manufacturing of a chikungunya vaccine in Africa.

NewsNew study highlights maternal-fetal TORCH infection risk
Researchers have assessed long-term trends in TORCH infections in India, a region where reliable data have been lacking. TORCH includes pathogens that cause toxoplasmosis, rubella, cytomegalovirus (CMV), herpes simplex virus and other infections.

NewsNew tool quickly sequences hantavirus genome
The genetic diversity of hantavirus and the low levels of virus typically found in patient samples make sequencing its genome particularly challenging. Researchers have developed a new, effective, and low-cost way to carry out whole genome sequencing for hantaviruses.

NewsMaternal RSV vaccine cuts infant hospitalizations by 70%
A study has found that vaccination against respiratory syncytial virus (RSV) during pregnancy reduced the risk of hospitalization in young infants by nearly 70%. It provides early real-world evidence from U.S. clinical care, showing that administering one dose of the maternal RSV vaccine (RSVpreF vaccine) reduces hospitalization related to RSV in young infants.

NewsFlu drugs show promise against cognitive decline
A class of flu drugs may reduce cognitive decline and premature aging in people living with chronic viral infection. Scientists identified a new biological culprit: the degradation of protective sugar molecules in our bodies, known as glycans, that normally help keep inflammation in check.

NewsData from patients hospitalised with COVID-19 made available to the scientific community
The DIVINE study database has been published. The cohort includes clinical information from 5,813 patients hospitalised with COVID-19 during four waves of the pandemic, between March 2020 and August 2021, across five hospitals in the southern metropolitan area of Barcelona.

NewsFever and chills can make respiratory diseases more contagious
A new study reveals that when the difference between body temperature and the ambient temperature is greater, the clouds of particles generated by coughing or sneezing disperse more and maintain a higher concentration.

NewsResearchers combine bacteria and viruses to demonstrate a new way to fight cancer
Researchers have designed non-toxic Salmonella bacteria to deliver viruses that are safe to humans but potent against liver and pancreatic cancer tumors. Animal models treated with this combination of bacteria and viruses saw almost all their tumors eliminated and lived significantly longer.
-
NewsNew model could help track deadly viruses back to their source
A new predictive model could help scientists more efficiently identify the reservoirs of emerging zoonotic viruses and dangerous pathogens like Ebola that can spill over from animals into humans. It relies on detailed information collected on suspected reservoir species to identify key windows.

NewsResearchers develop new vaccine adjuvant that could make it easier to eradicate polio
Researchers have now come up with a way to modify the injectable polio vaccine so that it can also promote a mucosal immune response. This vaccine could help to achieve polio eradication while avoiding the risks of the oral polio vaccine.

NewsThe future of phage therapy will be decided by more than science alone
As antimicrobial resistance accelerates worldwide, leading experts gather in Valencia to address the scientific, regulatory, manufacturing and clinical challenges that will determine whether phage therapy becomes a routine healthcare solution.

NewsStudy reveals core values that drive Black and Hispanic parents’ decisions on vaccinating their kids against COVID-19
Persistently low rates of COVID-19 vaccination in Black and Hispanic children suggest that parents in these communities tend to be hesitant about the vaccine for their kids, even when they have received it themselves. A new study sheds light on the factors influencing decisions about vaccination.
