NewsBody lice may be bigger plague spreaders than previously thought
A new laboratory study suggests that human body lice are more efficient at transmitting Yersinia pestis, the bacterium that causes plague, than previously thought, supporting the possibility that they may have contributed to past pandemics.

NewsNew tool may help prioritize high-risk infants for RSV immunization
On the heels of a shortage of nirsevimab for infant respiratory syncytial virus (RSV) lower respiratory tract infection (LRTI) prevention, a new tool may help identify newborns at highest risk for developing serious infections.

NewsStudy sheds light on bacteria associated with pre-term birth
Researchers have found that multiple species of Gardnerella, bacteria sometimes associated with bacterial vaginosis (BV) and pre-term birth, can coexist in the same vaginal microbiome.

NewsForget the freezer - air-dried soils will still give up their microbial secrets
Scientists have found that soil stored under refrigerated or air-dried conditions can still retain the needed information for understanding microbial community composition and structure for many years.

NewsHow vaccine messaging is framed makes a difference, new research reveals
A one-size-fits-all approach to communicating the benefits of vaccines isn’t effective. Message framing plays a crucial role depending on the mindset, so it requires communicating in different ways for different people, a new study says.

NewsGut bacteria boost immune response to fight tumors
Roughly one in five cancer patients benefits from immunotherapy – a treatment that harnesses the immune system to fight cancer. Such an approach to beating cancer has seen significant success in lung cancer and melanoma, among others. Optimistic about its potential, researchers are exploring strategies to improve ...

NewsFrom fungi to fashion: mushroom eco-leather is moving towards the mainstream
As fashion designers look for alternatives to leather, growing mycelium – or fungi-based – ‘leather’ substitutes using a new paste media has opened up the possibility of growing this bio-fabricated material faster, and of cultivating it more easily.

NewsBreakthrough research identifies mechanism behind drug resistance in malaria parasite
A new study has found that a cellular process called transfer Ribonucleic acid (tRNA) modification influences the malaria parasite’s ability to develop resistance to Artemisinin-based combination therapies.

NewsA trial HIV vaccine triggered elusive and essential antibodies in humans
An HIV vaccine candidate triggered low levels of an elusive type of broadly neutralizing HIV antibodies among a small group of people enrolled in a 2019 clinical trial.

NewsRegenerating worms have genetic control over their algal partners
Researchers have found that when Convolutriloba longifissura, a species of acoel that hosts the symbiotic algae Tetraselmis, regenerates, a genetic factor that takes part in the acoel regeneration also controls how the algae inside of them reacts.
