New blood test can check for at least 50 types of cancer before symptoms of disease

April 1, 2020

New research from the UK and US, including the Dana-Farber Cancer Institute (DF) and University College London, has found a simple blood test can screen for more than 50 types of cancer. The test looks for telltale chemical changes to cell-free DNA that leak from tumours into the bloodstream, with mostly (96%) accurate diagnoses. The […]

UK study finds weight gain may reduce risk of breast cancer before menopause

March 31, 2020

Breast cancer is the most common cancer among women – according to the World Health Organization – and also accounts for the highest number of cancer-related deaths. But new research led by the Institute of Cancer Research (ICR), London, suggests that weight gain may have a protective effect against breast cancer– it has found that […]

Graphite nano-coating kills bacteria infesting implants, as designed by Swedish scientists

March 27, 2020

A new, antimicrobial implant coating, using carbon-based nanoplatelets, has been developed by scientists at Chalmers University of Technology (Chalmers) in Sweden – the vertically-protruding nanoplatelets can slice through the protective outer membrane of bacteria that might otherwise colonise the implant, effectively killing it. Human cells will not be harmed, because a human cell is about […]

NIH finds new coronavirus stable for hours on everyday surfaces

March 23, 2020

A new study led by scientists from the National Institutes of Health (NIH), US, has found that the new coronavirus, which causes the deadly respiratory disease COVID-19, remains stable for hours on various surfaces, and suggests that people may acquire the virus through the air and after touching contaminated objects. The study also provides key […]

Charged nanoparticles compromise waste disposal unit, kills cancer cells

March 20, 2020

Cancer cells’ garbage disposal systems, or lysosomes, are particularly vulnerable to internal attacks as opposed to those of healthy cells. Lysosomes are tiny sacs packed with enzymes and acids that degrade unwanted parts of the cell, before either recycling or ejecting the waste components. Scientists from South Korea’s Institute of Basic Science (IBS) have found […]

US researchers find falling estrogen levels in women can lead to muscle loss

March 19, 2020

A study from the University of Minnesota Medical School (UMN-Med) in Minneapolis has recently established that estrogen is essential in females for maintaining muscle stem cell health and function. The associated animal study showed that a lack of estrogen or genetic deletion of the estrogen receptor in muscle stem cells led to a 30 to […]

Gene-deficient bone marrow cells induce cancer tumour regression; slows tumour growth

March 13, 2020

An immunotherapy approach known as adoptive cell therapy, in which altered versions of a patient’s own cells are used to trigger a more heightened immune response to cancer, has been observed to slow the growth of prostate and pancreatic cancers in mice. Scientists at Johns Hopkins Sidney Kimmel Comprehensive Cancer Center in Baltimore, US, recently […]

Calorie restriction can protect against aging in cellular pathways, US-China study finds

March 6, 2020

Inflammatory response(s) characteristic of human aging can apparently be reversed by calorie-restriction, as observed by scientists from the Salk Institute for Biological Studies (Salk) in California, US, and collaborators from the Chinese Academy of Sciences (CAS) in Beijing, China. Caloric restriction has been previously shown, in animal models, to be an effective intervention against age-related […]

Machine study of brain scans puts forth new ideas to schizophrenia

March 4, 2020

The American Psychiatric Association (APA) dismissed a number of different diagnostic classifications for schizophreniain 2013 citing “limited diagnostic stability, low reliability, and poor validity” – the classifications were then based on observations of behavior and symptoms. Now, new research led by scientists from the University of Pennsylvania (UPenn) using a machine learning method called HYDRA […]

Deleted DNA segment linked to ventricular enlargement in schizophrenia

February 26, 2020

Patients may suffer from what is known as “auditory hallucinations” in schizophrenia – they hear often distressing and distracting “voices” due to enlarged cerebral ventricles, which afflicts nearly 80% of schizophrenic individuals. Uncovering the biological origins of auditory hallucinations is the first step to reducing the overall disease burden of schizophrenia – developmental neurobiologists at […]
