NewsClose contact within households may not influence COVID-19 transmission
A study measuring the impact of close contact on SARS-CoV-2 virus transmission within households suggests that being in proximity to someone with the virus may not influence the likelihood of becoming infected.
-
NewsMulticellular life on Earth ‘didn’t arise as described in textbooks’
Oxygen didn’t catalyze the swift blossoming of Earth’s first multicellular organisms, a new study says, defying a 70-year-old assumption about what caused an explosion of oceanic fauna hundreds of millions of years ago.

NewsPicolinic acid reveals its broad-spectrum antiviral abilities
Picolinic acid, a natural compound produced by mammalian cells, can block several disease-causing viruses such as SARS-CoV-2 and influenza A viruses, according to a new study.
-
NewsScientists track global atmospheric spread of harmful microbes
Researchers have published an article that helps to understand the intercontinental spread of harmful microorganisms through the atmosphere.
-
NewsGlobal overview of antibiotic resistance determinants yields surprising findings
Scientists have developed a statistical model of the main determinants behind worldwide antibiotic resistance dynamics based on a large-scale spatial-temporal analysis.
-
NewsStudy suggests the carbon cycle is speeding up
In Northern ecosystems, rising temperatures are depleting the soil carbon reservoir, a new study reveals.
-
NewsNew cholera substrains in Bangladesh uncovered by genomic surveillance
Researchers have uncovered two new cholera substrains in a displaced refugee population in southern Bangladesh, where a pre-emptive mass vaccination campaign of over one million refugees was successful in preventing an epidemic.
-
NewsResearchers discover novel biomarker for sepsis severity
Scientists have identified a novel biomarker that could change the way sepsis is approached and treated.
-
NewsScorpionfish protein kills drug-resistant bacteria from patients with cystic fibrosis
A scorpionfish protein effectively kills antibiotic-resistant bacteria from patients with cystic fibrosis, escaping an immune response that renders the human version of the protein ineffective.
-
NewsResearchers uncover mechanisms underlying Helicobacter pylori-induced gastric cancer
A new study shows how oncoprotein CagA from Helicobacter pylori disrupts Wnt/PCP signalling and promotes gastric carcinogenesis.
-
NewsScent dogs can detect COVID-19 more rapidly and accurately than current tests
Scent dogs may represent a cheaper, faster and more effective way to detect COVID-19, and could be a key tool in future pandemics, a new review of recent research suggests.
-
NewsOmicron subvariant BA.5 efficiently infects lung cells
Over the course of evolution of Omicron subvariants, viruses may arise that regain the ability to effectively spread in the lung and cause severe illness in risk patients and people with insufficient immunity, a new study suggests.
-
NewsBioluminescent bacteria coordinate signalling to colonize squid’s light organ
Researchers reveal how bioluminescent bacteria coordinate their behaviour to colonize the Hawaiian bobtail squid through cellular signaling and cues from the environment.
-
NewsBacteria discreetly living in throat are primary source of Strep A transmission
Breakthrough research has found that Group A Streptococcus (GAS) infections are more likely transmitted from asymptomatic throat carriage than skin-to-skin contact in communities with high rates of infection.
-
NewsBacterial protein may contribute to reduced fertility and birth defects
Scientists have published new findings that emphasize the crucial role of the urinary and genital tract microbiota in adverse pregnancy outcomes and genomic instability that originate in the womb during foetal development.
-
NewsDiscovery of new gene unveils sex determination in green algae
Scientists determine how female and male reproductive cells develop in volvocine algae.
-
NewsCell wall of Lyme disease pathogen causes lingering symptoms
The National Institutes of Health awarded a College of Agriculture and Life Sciences researcher $2.7 million to understand how the cell wall of the Lyme disease-causing pathogen makes people sick.
-
NewsChanging sponge microbiome triggers gene regulation modifications
Researchers demonstrate that sponges react to changes in their microbiome with extensive modifications in gene regulation.
-
NewsHigh-res map of the human placenta reveals COVID virus hideouts
Researchers have developed a high-resolution map of the human placenta visualizing an array of different immune microenvironments in healthy placentas from uninfected pregnancies, and those from pregnancies affected by COVID infections.

NewsStudy supports ‘catch up’ HPV test in older women
Screening recommendations for women over age 65 have been lacking empirical evidence, but a new study has found that older women who received a ‘catch up’ screening intervention were more likely to be diagnosed with cervical neoplasia.
