NewsZoo poo might hold the secrets to new medical treatments
Scientists are hoping the collection of poo from tigers, elephants, giraffes and other exotic animals, could contain the secret to finding new medical treatments. Although a waste product to the animals, hidden amongst it are thousands of phages which are potentially capable of fighting bacterial infections.

NewsUnlocking how bacteria bounce back after antibiotics
A groundbreaking study has uncovered how Escherichia coli (E. coli) persister bacteria survive antibiotics by protecting their genetic instructions. The work offers new hope for tackling chronic, recurring infections.

NewsLess is more: Gene loss drives adaptive evolution of a pandemic bacterium
A study reveals a surprising evolutionary insight: sometimes, losing genes rather than gaining them can help bacterial pathogens survive and thrive. The research focused on Vibrio parahaemolyticus, a bacterium behind many of the seafood-related infections worldwide.

News‘Migrion’ – a chimeric structure of virus and migrasome, a novel unit for intercellular viral transmission
Researchers found that in infected cells, nucleic acids and proteins of vesicular stomatitis virus (VSV) are actively transported into migrasomes, newly characterized cellular structures generated specifically during cell migration.

NewsTherapeutic vaccination against HPV-related tumors: Nanoparticles make the difference
Researchers have developed a therapeutic vaccination concept that can mobilize the immune system to target cancer cells. Virus peptides coupled to silica nanoparticles can elicit effective T-cell responses against HPV-related tumors. In a mouse model, the nanoparticle-based vaccine was able to partially or completely suppress HPV-related tumors.

NewsAncient mammoth remains yield the world’s oldest host-associated bacterial DNA
An international team has uncovered microbial DNA preserved in woolly and steppe mammoth remains dating back more than one million years. The analyses reveal some of the world’s oldest microbial DNA ever recovered, as well as the identification of bacteria that possibly caused disease in mammoths.

NewsMicroalgae are more significant for carbon dioxide absorption in the Southern Ocean than previously thought
14,000 years ago, algal blooms in the Southern Ocean helped to massively reduce the global carbon dioxide content of the atmosphere – as has now been revealed by new analyses of ancient DNA. Declines in sea ice pose a serious threat to these algae.

NewsNew pimple patches deliver a powerful remedy to unwanted zits
Researchers have designed a two-stage pimple patch set with an array of tiny spikes that grabs onto the pimple and delivers antibacterial or anti-inflammatory compounds. Human clinical trials confirmed that the pimples disappeared after seven days of treatment.

NewsMicrobiologists uncover bacteria that remove toxic sulfide and use iron minerals for growth
An international team of scientists has discovered a new microbial metabolism: so-called MISO bacteria “breathe” iron minerals by oxidizing toxic sulfide. The previously unknown biological process sees versatile microbes remove toxic sulfide and use it for their growth.
