NewsModeling premature aging in yeast reveals key effects of progerin on cellular lifespan
Researchers developed a yeast-based model to study premature aging by expressing Progerin, the toxic protein responsible for Hutchinson–Gilford Progeria Syndrome. Using genetically engineered yeast cells, they compared the effects of Progerin with its normal counterpart, Lamin A.

NewsScientists explore the bidirectional skin-brain axis: Mental health, dermatology-related quality of life, and the role of probiotics
Researchers investigating associations between mental health, dermatology-related quality of life (DLQI), and probiotic intake in 305 Brazilian adults found that women had significantly higher scores for anxiety, depression, and stress compared to men.

NewsLong-term cure rates for multidrug-resistant tuberculosis much better than expected
A new national cohort study from Latvia provides important insights into the treatment of multidrug-resistant tuberculosis (MDR-TB). The study shows that long-term disease-free survival rates are significantly higher than previous standard indicators suggest.

NewsHong Kong’s waters at risk from over-the-counter drug pollution
A recent study of Hong Kong’s river and estuary systems has uncovered an overlooked major source of water pollution: common over-the-counter (OTC) drugs. Accessible, everyday OTC drugs accounted for up to 85% of pharmaceutical pollution in these waters during the wet season.

NewsViruses found in Antarctic air, including some new to science
It may seem stark and lifeless, but the air around the remote sub-Antarctic island of South Georgia contains viruses, including some that are new to science. Using metagenomics, researchers discovered that South Georgia harbours a diverse and dynamic airborne viral community.

NewsHow gut bacteria and acute stress are linked
Researchers have demonstrated for the first time that, in healthy adults, the diversity of gut bacteria and their capacity to produce certain metabolites are associated with the acute stress response - particularly stress reactivity.

NewsAncient viruses serving as gene delivery couriers to help bacteria resist antibiotics
Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR).

NewsDon’t build the engine, grow it: biohybrid miniature robots using living organisms
By fusing living organisms like bacteria, algae, and insects with synthetic payloads, researchers are creating living biohybrid miniature robots that self-fuel, self-repair, and navigate environments that would paralyze a rigid silicon chip.

NewsFoxes and birds could be ‘early warning system’ to survey spread of antibiotic resistance into ecosystems
Wildlife monitoring could alert us to the spread of highly antibiotic resistant bacteria into unexposed ecosystems, highlighting a potential public health strategy.

NewsAncient tooth reveals the bacterium responsible for scarlet fever was not introduced to the Americas by Europeans
A research team has identified the Streptococcus pyogenes bacterium in a pre-Columbian Bolivian mummy and, for the first time, reconstructed the genome of this centuries-old pathogen.

NewsThe giants of the reef: New citizen science project races to document centennial corals
Coral reefs hide “scientific treasures” that have survived for centuries, yet many of these giant, ancient organisms remain largely unknown to science. A new study introduces a pioneering citizen-science initiative to find these giant coral colonies before they are lost to escalating global pressures.

NewsNovel research reveals the active role that skin cells play in rabies infection
A new study provides direct evidence that keratinocytes can support viral replication and transmit the rabies virus to neurons. The investigators offer a mechanistic explanation for how superficial skin exposures from scratches or minor bites by dogs and bats can lead to neuroinvasion.

NewsStudy reveals new way to strengthen immunity against the flu
A new vaccine model targets epitopes, specific but distinct regions of the protein on the surface of the influenza virus. The model includes different versions of epitopes in hopes of redirecting how the immune system responds.

NewsResearchers synthesize photosynthetic molecule found in bacteria
Researchers have successfully synthesized bacteriochlorophyll a, a photosynthetic pigment found in bacteria which absorbs infrared light. The work represents the first chemical synthesis of this molecule and could give scientists deeper insights into photosynthetic function and photosynthetic energy.

NewsPoor hygiene and food handling practices increase the risk of bacterial outbreaks in Brazilian households
A significant number of Brazilians engage in improper food hygiene and handling practices at home. Examples include washing meat in the kitchen sink and failing to properly wash vegetables.

NewsAs syphilis cases rise, study links infection with higher risk of stroke, heart attack and other serious cardiovascular problems
Adults with later-stage syphilis are more likely to develop major cardiovascular problems – including stroke, heart attack or aortic aneurysm – than similar patients without the infection. The increased risk is primarily found in those whose infection progressed longer than a year.
-
NewsStudy: Microbes show almost universal potential for biodegrading plastics
Researchers have identified more than 600,000 microbial proteins capable of breaking down natural and synthetic plastics, revealing a far broader biodegradation potential across microbes than previously known.
-
NewsSelf-propulsion or slow diffusion: How bacteria, cells, and colloids respond to stimuli
One enables them to quickly leave an environment; the other helps them move toward where they are needed. In microorganisms, as well as in artificial structures, these are the movements triggered in response to incoming and outgoing signals.

NewsFirst continent-wide map of dominant avian influenza strain explains its spread
Scientists provided the most complete view of bird flu’s spread through wild bird populations across North America, explaining how the dominant strain advanced, maintaining the risk of human infections.

NewsStudy reveals genome-wide host–virus genetic interactions in cancer risk
Researchers report a major advance in understanding how interactions between human and viral genomes shape disease risk. They found that variations in the Epstein–Barr virus, together with a specific immune-related gene (HLA-A*11:01), strongly influence the risk of nasopharyngeal cancer.
