NewsNew gel-based system allows bacteria to act as bioelectrical sensors
Researchers have developed a safe bioelectronic sensor that allows for effective electronic communication even in liquid environments. The system uses the naturally occurring polymer chitosan, acting as a kind of shell to keep the bacteria from escaping.

NewsPenicillin–streptomycin influences macrophage mechanical properties and microenvironment mechano-sensation
A foundational finding in mechanobiology reveals that penicillin-streptomycin (pen-strep), the antibiotic mixture universally added to mammalian cell culture media, is not a biologically inert antimicrobial agent.

News Natural dye produced by Amazonian fungus can be used in cosmetics
A red extract made from Talaromyces amestolkiae was tested in the bases of potential products, including face cream, shampoo, and gel sticks, for its antioxidant and antibacterial properties.

NewsAntibacterial coatings with short-term effect may fail over longer periods of time
Researchers have shown that antibacterial coatings which initially appear highly effective at destroying bacteria may lose their performance over time. Therefore, long-term testing is essential for developing the best antibacterial materials.

NewsScientists develop shape-shifting scaffold that fights infection and rebuilds bone
Scientists have developed a body-temperature–responsive, 3D-printed shape-memory scaffold coated with a metal–polyphenol network to treat infectious bone defects. It is designed to adapt to irregular bone defects while providing antibacterial activity, immune regulation, and osteogenic support.

NewsBacterial cellulose as a sustainable vehicle for the controlled release of nisin and mandelic acid: A clean beauty-based approach for acne treatment
A new study developed a bacterial cellulose-based delivery system loaded with nisin and mandelic acid, targeting acne treatment. Bacterial cellulose, derived from Komagataebacter xylinus, served as a biocompatible, biodegradable matrix to control the release of bioactive compounds.

NewsFe₃O₄@mPEG-Ag nanoparticles: a new frontier in combating antibiotic resistance
A collaborative study introduces Fe₃O₄@mPEG-Ag nanoparticles (NPs) as a groundbreaking non-antibiotic strategy to combat drug-resistant bacteria, offering the antibacterial properties of silver (Ag) with the stability and biocompatibility of magnetite (Fe₃O₄) modified by methoxy poly(ethylene glycol) (mPEG).

NewsImaging technique is step towards needed treatments for hantaviruses in new molecular ma
Researchers have produced a detailed blueprint, the highest resolution yet, for a protein complex the Andes virus uses to infect host cells. The new detailed structural information enabled the researchers to produce a vaccine candidate that caused mice to produce neutralizing antibodies against the Andes virus.

NewsAcoziborole Winthrop receives European Medicines Agency positive opinion as three-tablet, single-dose treatment for most common form of sleeping sickness
The European Medicines Agency has granted a positive opinion to Acoziborole Winthrop (acoziborole) as a single-dose oral treatment for both early- and advanced-stage gambiense sleeping sickness in adults as well as in adolescents 12 years and older weighing at least 40 kilograms.

NewsScientists uncover mechanism used by three bacteria-killing viruses to target transporter
Biochemists have homed in on an underexplored small transporter called MurJ that is a vital part of the pathway bacteria use to build their chain-mail-like cell wall. Using advanced tools, the scientists have determined the common mechanism used by three different bacteria-killing viruses to block MurJ from doing its job.

NewsSingle daily pill shows promise as replacement for complex, multi-tablet HIV treatment regimens
A phase 3 clinical trial has shown that a new, daily oral tablet that combines two current HIV treatment medications – bictegravir and lenacapavir (BIC/LEN) – may simplify treatment significantly for people with HIV who currently take very complex treatments.

NewsNew strategies aim at HIV’s last strongholds
A new study has overcome a long-standing challenge—how to isolate and study elusive HIV-infected cells called authentic reservoir clones (ARCs) that evade the immune system, making the disease difficult to cure.

NewsScientists develop first-of-its-kind antibody to block Epstein Barr virus
Using mice with human antibody genes, scientists have developed new genetically human monoclonal antibodies that prevent two key antigens on the surface of the Epstein Barr virus (EBV) from binding to and entering human immune cells.
-
NewsNew antibody–drug conjugate strategy to block HIV infection
New antibody–drug conjugates (ADCs) combine a CD4 mimic with neutralizing antibodies for enhanced suppression of HIV infection. By targeting the gp120 on the viral envelope via a two-step mechanism, the ADCs effectively block viral entry.

NewsRhododendron-derived drugs now made by bacteria
Bioengineered E. coli bacteria can now produce a group of compounds with anticancer, anti-HIV, antidiabetic and anti-inflammatory activities. The compounds, orsellinic acid-derived meroterpenoids, are produced by Rhododendron species.
