A new scientific study shows that exposure of preschool children to bright electric light in the evening suppresses melatonin production almost completely, an important addition to the growing body of research in this area. Melatonin suppression is a marker of disruption of our circadian rhythms. Ten kids, ages 3 to 5, were […]

Scientists have identified the molecular mechanism that leads to the death of neurons in amyotrophic lateral sclerosis (also known as ALS or motor neurone disease) and a common form of frontotemporal dementia. Writing in Cell, the researchers from the University of Cambridge and University of Toronto also identify potential therapeutic targets for these currently incurable […]

Back in 2013, researchers achieved human brain organoids for the first time, which they had eventually managed to induce to form structures like those seen in the brains of foetuses. The problem with the brainy organoids is their short life-span. “In our hands, the organoids stop growing around five weeks,” […]

Infection with Epstein-Barr virus (EBV), the cause of infectious mononucleosis, has been associated with subsequent development of systemic lupus erythematosus and other chronic autoimmune illnesses, but the mechanisms behind this association have been unclear. Now, a novel computational method shows that a viral protein found in EBV-infected human cells may […]

Most of the roughly 15.5 million cancer survivors in the U.S. receive chemotherapy, and roughly 65 percent develop some degree of the chemotherapy-induced nerve damage known as peripheral neuropathy. Peripheral neuropathy simply means nerves outside of the brain and spinal cord are affected, and symptoms include numbness and tingling in […]

The method involves the use of a new type of a nanotube – a tiny tube used in many applications, including drug delivery. This new type, designed and created by Dr Ben Newland at Cardiff University, is made from a non-toxic polymer called poly(ethylene glycol).  Unlike current nanotubes, which can cause […]

New research, published in Biological Reviews and conducted by researchers from the University of Liverpool and Escola Superior de Ciências da Saúde (Brasília, Brazil) has found some type of cancers unique to humans may be a result of evolutionary accidents. Cancer is a major cause of death worldwide. But humans are not […]

All of the body’s organs contain macrophages, which, as part of the immune system, consume bacteria and other foreign bodies. However, macrophages are also specialised according to the organ in which they operate; in the brain they are known as microglia, and researchers believe that this specialisation is controlled by […]

The small, pilot study aims to recruit seven people to find out if the bone marrow stem cell mobilising drug, granulocyte-colony stimulating factor (GCSF), could improve blood markers and potentially treat the condition. GCSF, which is commonly used in diseases related to the blood, as well as in healthy people […]

New research published in The Lancet and co-authored by Professor Lucilla Poston CBE, shows that the diet and lifestyle of both parents before conception plays a key role in the long-term health of their children. In a series of papers Professor Poston, Head of King’s School of Life Course Sciences, and colleagues from […]

Older adults who take a novel antioxidant that specifically targets cellular powerhouses, or mitochondria, see aging of their blood vessels reverse by the equivalent of 15 to 20 years within six weeks, according to new CU Boulder research. The study, published this week in the American Heart Association journal Hypertension, […]

Cancer is not as scary as it used to be. Of course, it is a terrible condition which causes a lot of deaths worldwide every year. But nowadays we have novel therapies to combat cancer, even though sometimes it is difficult to say what is and what isn‘t working. Now […]

Non-Hodgkin lymphoma, a cancer that is diagnosed in the U.S. more than 70,000 times annually, arises from overly proliferating immune cells within the body’s lymph nodes, which are connected to a network of lymph vessels through which lymphatic fluid flows. The most common type of lymphoma is diffuse large B-cell […]

Despite the great successes of targeted cancer drugs and the promise of novel immunotherapies, the vast majority of people diagnosed with cancer are still first treated with chemotherapy. Now a new study by UCSF researchers using techniques drawn from computational biology could make it much easier for physicians to use […]

Twenty years ago this fall, a team of scientists led by James Thomson at the University of Wisconsin–Madison published the first paper describing successful derivation of human embryonic stem cells. The discovery of these master human stem cells empowered a new and promising direction in biomedical research, and for the […]

“Night owls” — people who like to stay up late and have trouble dragging themselves out of bed in the morning — have a higher risk of dying sooner than “larks,” people who have a natural preference for going to bed early and rise with the sun, according to a […]

A new blood test using gold nanoparticles could soon give oncologists an early and more accurate prognosis of how cancer treatment is progressing and help guide the on-going therapy of patients. Researchers at The University of Queensland have developed new nanotechnology to monitor the diversity of individual cancer cells circulating […]
