NewsHas life-saving HIV therapy contributed to increased rates of a sexually transmitted disease?
A study has uncovered an unintended consequence of a major medical breakthrough: while the availability of HIV treatments in the late 1990s dramatically improved survival, they also contributed to a resurgence in syphilis, a sexually transmitted infection.

CareersQ&A: Meet Letters in Applied Microbiology junior editor Daniel Jesuwenu Ajose
We caught up with Daniel Jesuwenu Ajose, a Postdoctoral Research Fellow at the School of Biology and Environmental Sciences, University of Mpumalanga in South Africa, who is one of the newest Junior Editors with Letters in Applied Microbiology

NewsConnected habitats help wildlife fight disease, strengthen protective microbes
Maintaining connections between natural habitats may support beneficial microbes that help wildlife defend against disease. A new study found that amphibians in connected natural forests and aquatic habitats were more likely to host beneficial skin microbes that inhibit a deadly fungal pathogen.

NewsLost millennium of Galápagos deep-sea corals linked to major Pacific climate shift
Scientists have discovered that deep-water corals in the Galápagos region vanished for more than 1,000 years before eventually recovering. The findings reveal that deep-water coral ecosystems may be more susceptible to climate change than previously thought.

NewsWorld-first shoe made entirely from pure mycelium unveiled at Milan Design Week
A prototype shoe made entirely from pure mycelium, the root-like network of fungi, will debut at Milan Design Week. The project is a collaboration between researcher and designer Lars Dittrich of Vrije Universiteit Brussel and head shoemaker Marie De Ryck at La Monnaie/De Munt.

NewsSome resilient fungi might survive the long voyage to Mars
Researchers recently identified fungi in samples from spacecraft-associated environments, including cleanrooms. Conidia grown from those fungi survived after exposure to simulations of the harsh conditions of Mars and space travel.

NewsScientists map how HIV hijacks human cells—and how cells can fight back
Scientists have opened a new door to understanding HIV by creating the first comprehensive genetic roadmap of how the virus interacts with real human cells. They identified a multitude of hidden players in HIV infection, human proteins that either help the virus thrive or work to stop it.

NewsPlastic texturing kills viruses when they land
Researchers have developed a thin plastic film that tears apart viruses on contact, offering a promising new way to keep high touch surfaces such as smartphones and hospital equipment from spreading disease.

NewsGut microbiome changes may signal Parkinson’s disease risk
Scientists have found that people with Parkinson’s disease have a distinctive makeup of gut microbes, as do healthy individuals who are genetically at risk of Parkinson’s disease. This could help to develop tests to reveal a person’s risk of developing Parkinson’s disease.

NewsSevere childhood malaria linked to cognitive impairment later in life
New findings suggest children who survive cases of cerebral malaria and severe malarial anemia experience cognitive and academic impairment that persists into adolescence.

NewsOral-gut axis points to salivary biomarkers for early gastric cancer detection
A recent study has identified distinct microbial “signatures” within the oral cavity and gut that serve as robust biomarkers for the early detection of gastric cancer (GC). Research shows how specific lactic acid-producing bacteria (LAB) migrate from the mouth to colonize the gastrointestinal tract.

NewsViruses enhance sulfamethoxazole removal in wetlands by modulating bacteria-phage interactions
A new study examines the role of viruses in sulfamethoxazole (SMX) removal in constructed wetlands. The research demonstrates that the addition of phage-concentrated solutions (PCS) enhances the degradation of SMX by enriching SMX-degrading bacteria.

NewsStudying two very different viruses helps to develop new strategies
When the SARS-CoV-2 pandemic began, virologist Theodora Hatziioannou, in conjunction with Paul Bieniasz brought her HIV-honed skills and tools to this new global threat, which made it easier and faster for researchers to gain insights into the virus and test antibodies for potential therapeutic candidates in real time.

NewsResearchers come up with novel strategies for coral restoration
Scientists have discovered a new way to help lab-grown baby corals survive through the early life stage. If young mountainous star corals are grown on cement tiles formulated with sodium carbonate, which raises the alkalinity of the water, they survive much better than the average lab-grown corals.

NewsScientists probe how neurons sense bacteria in the gut
Neural interaction with bacteria, e.g. in the gut microbiome, has important effects on brains of animals from worms to people. A new study investigates how neurons sense bacteria by revealing, in nematodes, the bacterial signals that a key neuron detects.

NewsWHO-recommended antibiotics cover only 1 in 4 neonatal sepsis infections in low- and middle-income countries
A major multi-country study has found that WHO-recommended first-line antibiotics for neonatal sepsis are likely to be effective in only one quarter of infections in low- and middle-income countries (LMICs).

NewsNew biosensor for detecting active tuberculosis
A research team is developing a sensor that paves the way for the rapid, selective and cost-effective detection of active tuberculosis. The device detects the presence of a protein secreted by Mycobacterium tuberculosis, the bacterium that causes the disease.

NewsGut bacteria predict skin cancer recurrence, but only when matched for ‘microbial fingerprint’
The specific mix of bacteria living in a person’s gut can predict the chances that melanoma will recur after surgery and immunotherapy, which helps immune cells target cancer cells, according to a new study.

NewsEngineered dual-bacterial sensors turn chemical signals into electricity
Most bacterial information transmission is done via electricity. While electricity-emitting bacteria exist, manipulating them into useful sensors has been quite challenging. Researchers recently developed a flexible bioelectrical sensor system called electroactive co-culture sensing system.

NewsSleep deprivation disrupts gut microbiota, worsening colorectal cancer outcomes
Researchers have found that the gut microbiota drives changes to the immune system caused by chronic sleep loss. These changes promote cancer progression, disrupt circadian rhythm and weaken the effectiveness of chemotherapy.
