Ohh nice! New vaccine science it seems though I’m not familiar with vaccines, this does seem like a novel approach. It’s kinda future proof to train the immune system to target proteins that are shared across all coronavirus’ I’m hoping it provides, as do they, that it provides a better solution than current vaccines.

The vaccine is made by attaching harmless proteins from different coronaviruses to minuscule nanoparticles that are then injected to prime the body’s defences to fight the viruses should they ever invade.

Because the vaccine trains the immune system to target proteins that are shared across many different types of coronavirus, the protection it induces is extremely broad, making it effective against known and unknown viruses in the same family.

Serial home tests would reduce unnecessary colonoscopy testing. Patients with suspected inflammatory bowel disease (IBD) could benefit from better testing protocols that would reduce the need and lengthy wait for potentially unnecessary colonoscopies, a new study has found.

In a paper published in Frontline Gastroenterology, researchers from the Birmingham NIHR Biomedical Research Centre (BRC) at the University of Birmingham tested a new protocol to improve IBD diagnosis combining clinical history with multiple home stool tests.

In the two-year study involving 767 participants, patients were triaged and had repeated faecal calprotectin (FCP) tests and the research team found that the use of serial FCP tests were able to strongly predict possible IBD as well as Crohn’s Disease and Ulcerative Colitis.

Scientists have found a way to restore brain cells impaired by a rare and life-threatening genetic disorder called Timothy syndrome.

A type of drug known as an antisense oligonucleotide allowed clusters of human neurons to develop normally even though they carried the mutation responsible for…

A therapy that restores brain cells impaired by a rare genetic disorder may offer a strategy for treating conditions like autism, epilepsy, and schizophrenia.

In a recent review published in the journal Nature Reviews Immunology, researchers discussed the limitations of current influenza vaccines and the potential for future vaccines to induce both T-cell responses and antibodies for enhanced protection. They examined the strategies to develop influenza vaccines with broad strain specificity and long-term efficacy, covering protection requirements, immune response evaluation, expected outcomes, and financial considerations.

Abstract. Long single-stranded DNA (ssDNA) is a versatile molecular reagent with applications including RNA-guided genome engineering and DNA nanotechnology, yet its production is typically resource-intensive. We introduce a novel method utilizing an engineered Escherichia coli ‘helper’ strain and phagemid system that simplifies long ssDNA generation to a straightforward transformation and purification procedure. Our method obviates the need for helper plasmids and their associated contamination by integrating M13mp18 genes directly into the E. coli chromosome. We achieved ssDNA lengths ranging from 504 to 20 724 nt with titers up to 250 μg/l following alkaline lysis purification. The efficacy of our system was confirmed through its application in primary T-cell genome modifications and DNA origami folding. The reliability, scalability and ease of our approach promise to unlock new experimental applications requiring large quantities of long ssDNA.

A previously unknown mechanism for inactivating genes that suppress tumor formation helps explain why cancer risk is associated with an unhealthy diet or unmanaged metabolic conditions like diabetes.

Researchers from Singapore and the UK used mouse models, human tissue, and human breast organoids grown in the lab to find that changes in glucose metabolism could help cancer grow by temporarily disabling a gene that protects us from tumors called BRCA2.

“These findings raise awareness of the impact of diet and weight control in the management of cancer risks,” says the first author of the new study, cancer pharmacologist Li Ren Kong from the Cancer Science Institute of Singapore (CSI Singapore).

Scientists at the Ineos Oxford Institute (IOI) have found a new potential combination therapy to combat antimicrobial resistance (AMR) by targeting two key bacterial enzymes involved in resistance.

Researchers identified a subcortical brain network that is thought to combine arousal and awareness, playing a key role in human consciousness.

A study recently published in Science Translational Medicine by researchers from Massachusetts General Hospital and Boston Children’s Hospital, both part of the Mass General Brigham healthcare system, introduces a connectivity map of a brain network. This map, the researchers suggest, is essential for maintaining human consciousness.

The study involved high-resolution scans that enabled the researchers to visualize brain connections at submillimeter spatial resolution. This technical advance allowed them to identify previously unseen pathways connecting the brainstem, thalamus, hypothalamus, basal forebrain, and cerebral cortex.
