‘Cellular chatter’: Researchers aim to decode communications within a tumor

Inside a tumor, chatter abounds. Multiple cell types are constantly communicating with each other, exchanging various types of information. Some are working together against the tumor, while others help the tumor grow. Researchers have a good handle on who the main players are, but it can be difficult to tell […]

UCLA Researchers Jump-Start Two Patients’ Brains, Leading to Recovery after Coma

Martin Monti, a Professor of Psychology and Neurosurgery at UCLA, and colleagues have recently published a paper in the journal Brain Stimulation, describing their success in jump-starting the brains of two patients in a long-term “minimally conscious state”. While Monti had already performed a similar procedure on a 25-year-old man […]

Immune cells are behind the depression experienced in inflammation

Special immune cells found in the brain, microglia, play a key role in the processes that make you feel uneasy and depressed in correlation with inflammation. The findings from a new study on mice suggest that microglial cells contribute to the negative mood experienced during several neurological diseases. David Engblom’s […]

Advocating the Use of Low Dose Ionizing Radiation as a Hormetic Treatment

Many forms of mild cellular stress produce benefits to health because they trigger the more efficient operation of cellular maintenance processes such as autophagy. That in turn causes better cell and tissue function, and thus improved health. This stress response and benefit is known as hormesis, and has been robustly […]

Researchers use patients’ cells to test gene therapy for rare eye disease

Scientists at the National Eye Institute (NEI) have developed a promising gene therapy strategy for a rare disease that causes severe vision loss in childhood. A form of Leber congenital amaurosis, the disease is caused by autosomal-dominant mutations in the CRX gene, which are challenging to treat with gene therapy.  The scientists […]

How does the immune system keep tabs on the brain?

Alzheimer’s disease, multiple sclerosis, autism, schizophrenia and many other neurological and psychiatric conditions have been linked to inflammation in the brain. There’s growing evidence that immune cells and molecules play a key role in normal brain development and function as well. But at the core of the burgeoning field of […]

Parkinson’s disease risk and severity is tied to the activity of a channel in cells’ ‘recycling centers’

Many genetic mutations have been found to be associated with a person’s risk of developing Parkinson’s disease. Yet for most of these variants, the mechanism through which they act remains unclear. Now a new study in Nature led by a team from the University of Pennsylvania has revealed how two different variations—one […]

New TAU study reveals “Achilles’ heel” of cancer cells

What makes cancer cells different from ordinary cells in our bodies? Can these differences be used to strike at them and paralyze their activity? Cancer researchers have been debating this question since the mid-19th century. A new study from Tel Aviv University (TAU) shows, for the first time, how an abnormal […]

First ever ‘pioneer’ factor found in plants enables cells to change their fate

Cells don’t express all the genes they contain all the time. The portion of our genome that encodes eye colour, for example, doesn’t need to be turned on in liver cells. In plants, genes encoding the structure of a flower can be turned off in cells that will form a […]

Study: Detecting ADHD with near perfect accuracy

A new study led by a University at Buffalo researcher has identified how specific communication among different brain regions, known as brain connectivity, can serve as a biomarker for attention deficit hyperactivity disorder (ADHD). The research relied on a deep architecture using machine-learning classifiers to identify with 99% accuracy those […]

Alcohol Causes Immediate Effects Linked to Heart Malady

A daily alcoholic drink for women or two for men might be good for heart health, compared to drinking more or not drinking at all. But while there is some evidence that drinking in moderation might prevent heart attacks, now a randomized, double-blinded clinical study of 100 heart patients has […]

Abnormal hyperactivation in the brain may be an early sign of Alzheimer’s

Abnormally hyperactive areas in the brain may help better predict the onset of Alzheimer’s disease, according to findings of a research team led by Université de Montreal researcher Sylvie Belleville, Scientific Director of the Institut Universitaire de gériatrie de Montréal research centre and professor in the Department of Psychology at […]

Genetic analysis of symptoms yields new insights into PTSD

Attempts to identify the genetic causes of neuropsychiatric diseases such as post-traumatic stress disorder (PTSD) through large-scale genome-wide analyses have yielded thousands of potential links. The challenge is further complicated by the wide range of symptoms exhibited by those who have PTSD. For instance, does extreme arousal, anger, or irritation […]

When — Not What — Obese Mice Ate Reduced Breast Cancer Risk

Restricting eating to an eight-hour window, when activity is highest, decreased the risk of development, growth and metastasis of breast cancer in mouse models, report researchers at University of California San Diego School of Medicine, Moores Cancer Center and Veterans Affairs San Diego Healthcare System (VASDSH). The findings, published in […]

Two Anti-viral Enzymes Transform Pre-Leukemia Stem Cells into Leukemia

Cancers, such as leukemia and multiple myeloma. The self-renewing nature of cancer stem cells makes them particularly hard to eradicate, and they’re often the reason a blood cancer reoccurs. Researchers at UC San Diego Health and University of California San Diego School of Medicine are working to understand what pushes […]

Keeping sperm cells on track

One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are antenna-like structures that protrude from most of the cells in our body, contain many microtubules. An example of flagell […]

How a Cancer Drug Carrier's Structure Can Help Selectively Target Cancer Cells

Porphyrins are interesting drug delivery vehicles that can specifically accumulate in cancer cells. However, how the structure of the drug-conjugated porphyrin affects its ability to penetrate and accumulate within cancer cells is not well understood. Researchers from the Tokyo University of Science now investigate the correlation between the structure and […]

Robust AI tools to predict future cancer

To catch cancer earlier, we need to predict who is going to get it in the future. The complex nature of forecasting risk has been bolstered by artificial intelligence (AI) tools, but the adoption of AI in medicine has been limited by poor performance on new patient populations and neglect to racial minorities.
