NewsMicrobiome transplants from wild and lab-reared mosquitoes spur differing gene expression in recipient mosquitoes
Mosquitoes that receive microbiome transplants respond differently depending on whether the donor was wild or lab-reared, a new study has revealed.

NewsSyphilis-like diseases were already widespread in America before the arrival of Columbus
Researchers at the Universities of Basel and Zurich have discovered the genetic material of the pathogen Treponema pallidum in the bones of people who died in Brazil 2,000 years ago. Source: Photo: Dr. Jose Filippini Skeleton at the site in Jubuicabeira II, Brazil. This is the oldest ...

NewsNew pieces discovered in the puzzle of first life on Earth
Researchers have found evidence dating to around 3.42 billion years ago of an unprecedentedly diverse carbon cycle involving various microorganisms.

NewsResearchers pinpoint most likely source of HIV rebound infection
Researchers used genetic sequencing techniques on the nonhuman primate version of HIV to identify that lymph nodes in the abdomen are the main source of rebound infection after the first week of stopping antiretroviral treatment.

NewsScientists uncover how coronavirus defends itself against our immune system
A research team identifies “protective switches” in the protein of the SARS-CoV-2 virus.

NewsStudy in mice uncovers new protective benefit of breast milk
An immune component of breast milk known as the complement system shapes the gut environment of infant mice in ways that make them less susceptible to certain disease-causing bacteria, according to a new study.

NewsFoodborne-pathogen Listeria may hide from sanitizers in multi-species biofilms
The finding could result in more effective sanitation procedures, leading to safer food supply, researchers said.

NewsHIV ‘secret handshake’ helps it reach cell’s centre to kickstart infection
New research reveals how the HIV capsid gets into the nuclear pore barrier channel.
-
NewsProtein may be the ‘glue’ that helps COVID virus stick
A study found that perlecan LG3 – a protein most commonly found in blood vessels and the brain – readily formed a stable bond with the COVID spike protein and perhaps enhanced the virus’ ability to bind with cells.

NewsVirus that infected the first animals now essential for development of the human embryo
All animals have evolved thanks to the fact that certain viruses infected primitive organisms hundreds of millions of years ago. Researchers now describe the role played by these viruses in a process that is absolutely vital for our development.

NewsNew tool reveals gene behavior in bacteria
Researchers showed that the way in which genes are turned on and off as bacteria grow provide clues to their regulation.

NewsCyanobacteria blooms intensify in Argentinian reservoirs
Research reveals cyanobacteria blooms have become more intense in Argentinian reservoirs, with positive records of cyanotoxins observed only in the last four years of the study period.
-
NewsScientists identify window of opportunity for treatment promoting HIV remission
Starting treatment four weeks after infection with HIV promotes long-term control of the virus following the interruption of treatment after two years of antiretroviral therapy.

NewsExperiment shows how predator mass mortality events affect food webs
A team of biologists experimentally caused a predator die-off to understand how rapid predator deaths affect freshwater ecosystems.
-
NewsComplex green organisms emerged a billion years ago
Using modern gene sequencing data, researchers investigating the evolutionary history of morphological complexity in streptophytes have pinpointed the emergence of multicellularity to almost a billion years ago.

NewsDisinfection is most effective way to prevent viral contamination of restroom surfaces
Closing the toilet lid before flushing does not reduce the spread of viral particles, a new study reveals.
-
NewsInfants born to COVID-infected mums have triple risk of developing respiratory distress
Vaccinating mothers prior to infection significantly reduced the risk for full-term infants developing a breathing disorder that most often strikes premature newborns.
-
NewsMutating hepatitis viruses make drug treatment more difficult
Sofosbuvir and Ribavirin combination therapy efficiently decreased viral RNA in blood and stool in patients with chronic HEV infection, but variants that are associated with antiviral resistance emerged during treatment.
-
NewsCooler conditions spur bacterial prey species to become the predator
In a new study, two species of bacteria grown in a lab reversed their predator-prey relationship after one species was grown at a lower temperature.

NewsSpace-grown salad more susceptible to foodborne infections than on earth
A research team finds lettuce and other plants are more susceptible to bacterial infections in space than on Earth.
