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.

The Rabbit R1 handheld AI device is a simple Android device, and a developer made the AI run on an iPhone.

The Rabbit R1 offers the ability to answer queries and perform tasks using AI, instead of using an iPhone directly. However, the work of one enterprising developer has resulted in a clone of the “iPhone-killer” which can run on an iPhone.

In X tweets on Monday, Will Hobick of Flutterflow posted that he would be posting a “cloneable template” of the Rabbit R1 app later in the week. In a follow-up post on Tuesday, he demonstrates a version of the app running on an iPhone.
