NewsMarine viruses use ‘hijacked’ genes to take over bacteria and exploit their energy systems
Marine viruses deploy a sophisticated Trojan horse maneuver that enables them to dismantle the energy systems of ocean bacteria and use the breakdown products for self-replication, according to a new study.

NewsGut microbiome connects obesity to cancer, impacting public health
A new review highlights growing scientific evidence that imbalances in gut bacteria can influence metabolism, trigger inflammation, and increase cancer risk. These insights offer new possibilities for disease prevention, early detection, and personalized health care.

NewsCircadian rhythms as a modulator of gut microbiota-tumor microenvironment crosstalk
A new review examines how circadian disruption modifies the diversity and metabolic functions of gut microbiota, resulting in alterations of microbial metabolites, including short-chain fatty acids and secondary bile acids.

NewsNew study identifies key mechanism driving HIV-associated immune suppression
Using humanized mouse models and blood samples from people living with HIV, resarchers found that reducing overactive plasmacytoid dendritic cells helped restore antiviral T cell function and shrink the viral reservoir.

NewsHospital bug jumps from lungs to gut, raising sepsis risk
A hospital-acquired bacterium that causes serious infections can move from the lungs to the gut inside the same patient, raising the risk of life-threatening sepsis, new research reveals.
-
NewsFive new phages discovered in university’s Botanical Gardens
Five new bacteriophages have recently been discovered in the ponds of Lund University’s Botanical Gardens. Phages thrive wherever bacteria are found, which often means ponds and watercourses that are rich in organic material.

NewsEmerging human and canine leptospirosis in New South Wales shows separate transmission pathways
A geospatial study of leptospirosis outbreaks in New South Wales suggests that humans and dogs may have largely independent transmission pathways.
-
NewsNew super pest combines broad spectrum of microbes
Researchers investigating what role the reed leafhopper’s microbial flora might have played in its rapid spread as a pest found it hosts at least seven species of bacteria and appears to be completely dependent on three of these species, which inhabit specific organs.
-
NewsClues to origins of complex life revealed with discovery of new unicellular organism and phylum
A new paper describes the discovery of Solarion arienae, a previously unknown unicellular organism that provides new insight into the earliest stages of complex life on Earth. This microscopic protist displays two distinct cell types and a unique predatory structure unlike any seen before.

NewsSnakebites: COVID vaccine tech could limit venom damage
The same technology used in COVID-19 vaccines could help prevent muscle damage from snakebites, according to scientists who say it could be even more useful for other conditions where toxins cause harm gradually, such as blocking harmful toxins produced by bacteria during infections.

News‘FluWarning’ system raises early alerts for virus spillovers
How can we monitor the cross-species transmission of avian flu? The answer is FluWarning, a digital system that reports abnormal changes in flu viruses. It analyses their genetic code, looking for subtle but significant changes that could indicate cross-species transmission.

NewsNew vaccine against a deadly virus acts fast and protects for over a year
A research team has developed a vaccine made from a non-infectious version of the Crimean-Congo hemorrhagic fever virus that protects quickly and provides long-lasting immunity.
-
NewsSoil carbon decomposition varies vastly, holding implications for climate models
A new study shows that even under uniform laboratory conditions, the rate of organic carbon decomposition in soil samples collected across the U.S. differed by up to tenfold, in part due to variations in soil mineral and microbial properties.
-
NewsNew flu strain underscores urgent need for vigilance, vaccination, and investment in virus science
Virologists have issued a statement on the emergence of a new influenza A (H3N2) variant known as H3N2 subclade K that is spreading rapidly and may contribute to a more intense flu season worldwide. Public health agencies have reported sharp week-over-week increases in cases driven by this subclade.

NewsNatural, non-engineered bacterium selectively targets colorectal cancer
Scientists have demonstrated that the marine bacterium Photobacterium angustum exhibits potent antitumor effects against colorectal cancer. The natural bacterium requires no genetic modification yet selectively accumulates in tumor tissues with minimal impact on healthy organs.
-
NewsTeam discovers cyanobacteria activate different genes by day and by night
By analyzing gene expression in the cyanobacterium Nostoc punctiforme, scientists discovered that during daylight, the cells focus on metabolism. But under cover of darkness, they turn to the control of genome repair and activate various genetic elements.

NewsNew research confirms HPV vaccination prevents cervical cancer
Two new Cochrane reviews show strong and consistent evidence that HPV vaccines are effective in preventing cervical cancer and pre-cancerous changes, especially when given to young people before they are exposed to the virus.
-
NewsRebalancing lung repair with immune damage is key to surviving severe influenza
Recovery from deadly influenza infection may hinge on helping the lungs heal in addition to stopping the virus, according to a new study in mice, which shows that pairing modest antiviral therapies with immune modulation can restore damaged tissues and lung function, even after severe infection has taken hold.
-
NewsToxic gut bacteria may drive ulcerative colitis by killing protective immune cells
A toxin-secreting gut bacterium may fuel ulcerative colitis by killing protective immune cells that maintain intestinal homeostasis, according to a new study. The findings suggest potential for new treatment strategies.

NewsHear us out: scientists say garlic shows promise as a mouthwash alternative
Garlic extract demonstrates antimicrobial efficacy comparable to other widely used antiseptics and disinfectants, such as chlorhexidine, according to scientists. While garlic-based mouthwash may cause more discomfort than chlorhexidine, it offers longer-lasting residual effects.
