By repurposing one of the human body's natural cargo transports, a research team has developed a vaccine platform that could curb certain engineering challenges, storage demands and side effects of vaccines that combat HIV epidemics and the COVID-19 pandemic.

New research provides rare evidence that natural hybridization can reduce the risk of extinction of species threatened by climate change. Researchers have identified genes that enable Rainbowfish to adapt to climate variations across the Australia using environmental models to work out how much evolution will likely be required for populations to keep pace with future climate change.

Stem cells have been modified to carry a therapy to treat companion animal patients with late-stage cancer, preserving good quality of life and extending their lives, potentially leading to better understanding of cancer treatments and their use in humans.

A new study has for the first time predicted which invasive species could pose a future threat to the UK's ecologically unique Overseas Territories.

High throughput sequencing (HTS) data is set to improve our knowledge of Physostegia chlorotic mottle virus biology, epidemiology, and genetic diversity.

A transporter which some bacteria use to recycle fragments of their cell wall has been discovered. Researchers found that the transporter controls resistance to certain kinds of cell-wall targeting antibiotics.

The World Health Organization (WHO) ranks antibiotic resistance as one of the top ten threats to global health. There is therefore a great need for new solutions to tackle resistant bacteria and reduce the use of antibiotics. A group of researchers are now presenting a new spray that can kill even antibiotic-resistant bacteria, and that can be used for wound care and directly on implants and other medical devices.

Scientific claims that babies harbor live bacteria while still in the womb are inaccurate, and may have impeded research progress, according to new research/

A new study suggests a way to re-energize critical killer immune cells that have become exhausted when fighting cancer or chronic viral infections.

Scientists have detailed a lifestyle switch that occurs in marine bacteria, where they change from coexisting with algae hosts in a mutually beneficial interaction to suddenly killing them.

Rapid economic growth has pushed rare species of big carnivores to the brink of extinction, but ecologists have suggested our appetite to once again live alongside big cats is increasing.

A new study finds that microorganisms live in richly diverse and interdependent communities in high-temperature geothermal environments in the deep sea. By constructing genomes of 3,635 Bacteria and Archaea from 40 different rock communities, researchers discovered at least 500 new genera and have evidence for two new phyla. Samples from the deep-sea Brothers volcano were especially enriched with different kinds of microorganisms, many endemic to the volcano. The genomic data from this study also showed that many of these organisms depend on one another for survival. Some microorganisms cannot metabolize all of the nutrients they need to survive so they rely on nutrients created by other species in a process known as a 'metabolic handoff.'

Federal environmental laws are failing to mitigate against Australia's extinction crisis, according to new research.

Microplastics -- tiny particles generated as plastics weather and fragment -- pose a growing threat to ecosystem and human health. A new laboratory study shows these threats extend beyond direct physical or chemical impacts, revealing that the presence of microplastics increases the severity of an important viral fish disease.

Researchers report that elephants play a key role in creating forests which store more atmospheric carbon and maintaining the biodiversity of forests in Africa. If the already critically endangered elephants become extinct, rainforest of central and west Africa, the second largest rainforest on earth, would lose between six and nine percent of their ability to capture atmospheric carbon, amplifying planetary warming.

Bacteria of the genus Enterobacter are among the most dangerous bacteria associated with hospital infections worldwide. Some of their representatives are highly resistant to commonly used antibiotics, so that the reserve antibiotic colistin is increasingly used as a last resort therapy option. To avoid unnecessary reliance on colistin and risk increasing resistance, bacteria are tested for sensitivity or resistance to colistin before recommending treatment. However, commonly used tests for Enterobacter are not reliable.

A potent plant toxin with a unique way of killing harmful bacteria has emerged as one of the strongest new antibiotic candidates in decades.
