Dangerous superbugs are clinging on to surgical gowns and instruments even after the items have been disinfected, scientists have revealed.
Hospitals have been warned to monitor their hygiene practices after tests showed the pathogen C. difficile is becoming resistant to standard decontamination agents.
The bug, which is thought to be responsible for around 1,600 deaths a year in the UK, can cause diarrhea, fever, rapid heartbeat, inflammation of the intestines, and kidney failure.
Scientists develop a new treatment for type-2 diabetes.
The biological computer is an implantable device that is mainly used for tasks like monitoring the body’s activities or inducing therapeutic effects, all at the molecular or cellular level. This is made up of RNA, DNA and proteins and can also perform simple mathematical calculations.
DNA computing is a branch of computing which uses DNA, biochemistry, and molecular biology hardware, instead of the traditional silicon-based computer technologies. Research and development in this area concerns theory, experiments, and applications of DNA computing.

The exact causes of aging are still not understood, and it is unclear why some species live less than 1 d, while others can live more than 400 y. Research suggests that telomeres are related to the aging process, but a clear relationship between the life span of a species and initial telomere length has not been observed. Here, we measure the telomere lengths of a variety of different species. We find that, in fact, there is no strong correlation between the life span of a species and initial telomere length. However, we find a strong correlation between the telomere shortening rate and the life span of a species.
Telomere shortening to a critical length can trigger aging and shorter life spans in mice and humans by a mechanism that involves induction of a persistent DNA damage response at chromosome ends and loss of cellular viability. However, whether telomere length is a universal determinant of species longevity is not known. To determine whether telomere shortening can be a single parameter to predict species longevities, here we measured in parallel the telomere length of a wide variety of species (birds and mammals) with very different life spans and body sizes, including mouse (Mus musculus), goat (Capra hircus), Audouin’s gull (Larus audouinii), reindeer (Rangifer tarandus), griffon vulture (Gyps fulvus), bottlenose dolphin (Tursiops truncatus), American flamingo (Phoenicopterus ruber), and Sumatran elephant (Elephas maximus sumatranus). We found that the telomere shortening rate, but not the initial telomere length alone, is a powerful predictor of species life span.
The Longevity industry will dwarf all other industries in both size and market capitalization and will require unprecedented sophistication in its approach for assessment and forecasting from the start to neutralize challenges and manifest opportunities
The Longevity Industry is not just about biotechnology and biomedicine. Rather, it consists of several distinct segments: Geroscience, Biomedicine, AgeTech and Finance. Despite this seemingly clear market segmentation, many of these sectors intersect with various domains of science and technology, such as advanced biomedicine, preventive medicine, digital health, AI, financial systems, pension systems and government national strategies.
One of the biggest challenges in assessing the Longevity industry is the extreme broadness of the sector. Hundreds of sectors, industries and domains of science and technology must be analyzed in order to obtain a concrete and comprehensive understanding of the dynamics, trends and direction of the industry. This situation is entirely unique to the Longevity industry. Due to this extreme level of complexity, realistic assessment and forecasting is extremely challenging, and the methods currently being applied for assessment of the biotech and biomedical industries are completely inadequate.
The past decade of Alzheimer’s disease research has been fraught with disappointment.
Years of focus on one hallmark of the disease ultimately resulted in no progress toward treatment or prevention.
But next week, when top scientists gather in Los Angeles at the Alzheimer’s Association International Conference, an annual meeting, many will present research on a different target: inflammation.
A simple cold virus could wipe out tumors in a form of bladder cancer, a small new study suggests.
Though the idea of using viruses to fight cancer isn’t new, this is the first time a cold virus effectively treated an early-stage form of bladder cancer. In one patient, it eliminated a cancerous tumor, the group reported July 4 in the journal Clinical Cancer Research.
A group of researchers conducted an early-stage clinical trial in which they infected 15 bladder cancer patients with coxsackievirus A21, which is one of the viruses that cause the common cold. Coxsackievirus is not a genetically modified virus; it’s “something that occurs in nature,” said senior author Hardev Pandha, a professor of medical oncology at the University of Surrey in England.
