NewsScientists evaluate in-vitro activity of ceftazidime-avibactam against carbapenem-resistant gram-negative bacteria
Scientists explored the in-vitro activity of ceftazidime-avibactam (CAZ-AVI) in clinical isolates of carbapenem-resistant gram-negative bacteria collected at the outpatient, emergency, and inpatient departments of the Indus Hospital, Karachi.

NewsResearchers reveal lipid-based communication between body and gut microbes
A new study shows how a host protein can specifically recognize bacterial lipids, thus triggering beneficial immune responses. It also highlights a new way the body actively shapes the gut microbiome by communicating with microbes to maintain balance.

NewsScientists develop an ink that boosts coral reef settlement by 20 times
With coral reefs in crisis due to climate change, scientists have engineered a bio-ink that could help promote coral larvae settlement and restore these underwater ecosystems before it’s too late.

NewsResearchers develop living material from fungi
Researchers have developed a bio-based material that is completely biodegradable, but also tear-resistant and has versatile functional properties. All this with minimal processing steps and without chemicals – you can even eat it. Its secret: It’s alive.

News New study reveals our skin’s own bacteria can help protect us from the bad effects of sunlight
Researchers have substantiated that certain skin bacteria can protect us from the sun’s ultraviolet (UV) radiation specifically by metabolizing cis-urocanic acid using an enzyme called urocanase. This enables the skin’s ability to fine-tune how it responds to UV radiation.

News‘Loop’hole: HIV-1 hijacks human immune cells using circular RNAs
In a groundbreaking discovery, researchers have identified a never-before-seen mechanism that enables the human immunodeficiency type 1 virus (HIV-1) to evade the body’s natural defenses and use it to support its survival and replication.

NewsFirst all-oral treatment for a rare but deadly strain of sleeping sickness now available
A handful of patients in Ethiopia, Malawi, Tanzania, Zambia, and Zimbabwe, as well as foreign travellers, have now been treated with a medicine that is revolutionizing care for patients with rhodesiense sleeping sickness.

NewsTo restore gut health, a healthy diet outperforms fecal transplants
When our microbial ranks are damaged or depleted — whether by inflammatory bowel diseases, antibiotic regimens or bone marrow transplants — it is crucial to restore them. According to a new study, the most effective way of rebuilding the microbiome is also the simplest: maintaining a healthy diet.

NewsScientists reveal key bacterial immune mechanism
Researchers have uncovered a pivotal mechanism by which bacteria defend themselves against viral infection. Cyclic dinucleotides (CDNs), synthesized during activation of the cyclic oligonucleotide-based anti-phage signaling system (CBASS) immune mechanism, trigger the filamentous assembly of phospholipase effectors, which execute the downstream immune response.

NewsNew study offers insights into designing safe, effective nasal vaccines
Researchers found that nasal vaccine boosters can trigger strong immune defenses in the respiratory tract, even without the help of immune-boosting ingredients known as adjuvants. The findings, researchers suggest, may offer critical insights into developing safer, more effective nasal vaccines in the future.

NewsChimpanzees use medicinal leaves to clean and treat their wounds
Scientists studying chimpanzees in Budongo Forest, Uganda, have observed that these primates don’t just treat their own injuries, but care for others, too — information which could shed light on how our ancestors first began treating wounds and using medicines.

NewsTough microbes found in NASA cleanrooms hold clues to space survival and biotech
A new study involving AMI member Professor Alexandre Rosado has reported 26 novel bacterial species growing inside cleanrooms associated with NASA space missions. They carry genetic traits associated with resilience to extreme environments.

NewsEchidna microbiome changes while mums nurse puggle
Research shows microbial communities in echidna pseudo-pouches undergo dramatic changes while the animal is lactating, which could help in creating an environment for their young, known as puggles, to thrive.

NewsNew discovery explains why men are more affected by severe COVID-19
Researchers have found another piece of the puzzle that explains why there are differences in immune responses in women and men when they get sick with COVID-19. This discovery has implications for treatment strategies for severe COVID-19.

NewsWily parasite kills human cells and wears their remains as disguise
The single-celled parasite Entamoeba histolytica gains resistance to the human immune system by ingesting proteins from the outer membranes of human cells and placing them on its own outer surface, a new study finds.

NewsMeasles virus detected in Houston wastewater before cases were reported
An innovative outbreak detection program that tracks disease-causing viruses in wastewater identified the measles virus in Houston samples collected in early January 2025, before cases were reported.

NewsViruses that kill toxic algae may increase risks for people and ecosystems
New laboratory research shows that when viruses attack a species that forms toxic algal blooms, those thick, blue-green slicks that choke waterways and that threaten ecosystems, drinking water, and public health, what results might be even worse than before the infection.
