NewsMarine microbes reveal extreme cooling ended the first human occupation of Europe
Paleoclimate evidence shows that around 1.1 million years ago, the southern European climate cooled significantly and likely caused an extinction of early humans on the continent, according to a new study.

NewsGut microbiome can increase risk and severity of HIV and EBV disease
Researchers have shown that the microbiome has a significant impact on the acquisition of Epstein-Barr virus (EBV) and human immunodeficiency virus-1 (HIV) infection and plays a role in the course of disease.

NewsGut microbiome diversity boosts survival in children receiving stem cell transplants
Researchers have shown that among children who have undergone a donor stem cell transplant, the presence of diverse species of micro-organisms in the intestinal tract beforehand resulted in significantly better overall patient survival and fewer complications.

NewsScientists reveal inner workings of Ebola’s ‘viral factories’
A new study reveals how the Ebola virus’s replication machinery forms fascinating microscopic structures inside host cells that become viral factories.

NewsSome phytoplankton can blitz neurotoxin methylmercury - even in the dark
In the search for ways to fight methylmercury in global waterways, scientists have discovered that some forms of phytoplankton are good at degrading the potent neurotoxin - even in the absence of sunlight.

NewsMolnupiravir dose of human effect size-equivalent blocks Covid transmission in ferrets
Two oral drugs provide equivalent therapeutic benefit in preventing severe COVID-19 in animal models, but only molnupiravir efficiently blocked SARS-CoV-2 transmission when administered at a human effect size-equivalent dose.

NewsModulating type 1 Interferon may expand treatment options for COVID-19
Researchers have, for the first time in nonhuman primates, studied how modulating the signaling of type 1 Interferon (IFN-I), one of the body’s initial defenses against infection, impacts SARS-CoV-2 viral replication and disease progression.
-
NewsScientists discover broadly neutralizing antibodies that contribute to HIV control
Researchers have investigated and revealed how neutralizing antibodies, including those described as broadly neutralizing, contribute to HIV control.

NewsResearchers reveal how the herpes virus HCMV deceives its host cells
Researchers have created a detailed map of the spatial interactions between viral and host cell proteins within HCMV particles, revealing that certain host cell proteins are recruited by viral proteins and play a role in viral replication.

NewsAspergillus fumigatus adapts to life in humans - and shapes their lung microbiome
Aspergillus fumigatus strains that infect humans have a significantly altered metabolism compared to other strains in the environment. At the same time, infection with the fungus leads to an apparent change in the human lung microbiome.
