This question is fundamental for infectious disease experts and people who study bacteria. Harmful pathogens, like Salmonella, find their way through a complex gut system where they are vastly outnumbered by good microbes and immune cells. Still, the pathogens navigate to find vulnerable entry points in the gut that would allow them to invade and infect the body. /news/2024-08-electric-current-gut-pathogens-salmonella.html Cell & Microbiology Molecular & Computational biology Wed, 21 Aug 2024 10:45:04 EDT news643455902 "Oh, hello.

The new lens works much like progressive lenses used for vision correction but without the distortions typically seen with those lenses. It could help advance contact lens technologies, intraocular implants for cataracts and miniaturized imaging systems. /news/2024-02-spiral-lens-vision-range-distances.html Optics & Photonics Thu, 08 Feb 2024 10:00:08 EST news626608806 One problem in gene therapy is that not all genes transfer equally well into the target cells. UZH researchers have now developed a flexible method to transfer large genes efficiently and without significant side effects. The approach has strong potential for therapeutic use. /news/2023-10-methods-effective-large-genes-gene.html Biotechnology Molecular & Computational biology Tue, 24 Oct 2023 09:37:03 EDT news617359021 In a recent study from the Wilmer Eye Institute, researchers say they found that using a nanoparticle to target immune cells in the eyes of zebrafish enhanced neuron regeneration rates after injury. This research expands on previous studies, from Wilmer and other institutions, which showed that immune cells (microglia) regulate retinal cell regeneration in zebrafish and mice models. /news/2023-06-nanoparticle-drug-delivery-super-enhances-neuron.html Bio & Medicine Thu, 22 Jun 2023 11:19:03 EDT news606651541 New findings in color vision research imply that humans can perceive a greater range of blue tones than monkeys do. /news/2023-05-people-monkeys.html Plants & Animals Evolution Mon, 01 May 2023 09:02:04 EDT news602150522 Corneal transplants can be the last step to returning clear vision to many patients suffering from eye disease.
