Under a microscope, it can be difficult to tell the difference between any two neurons, the cells in our brain responsible for storing and processing information. The mammalian brain contains … Continue Reading New technique identifies previously unknown human neurons.
Over the past three decades DNA has emerged as an exceptional molecular building block for nanoconstruction due to its predictable conformation and programmable base-pairing interactions. DNA nanotechnology is the design … Continue Reading Low-cost DNA nanobot can detect many diseases, including HIV.
A lab-on-a-chip is a device that integrates one or several laboratory functions on a single chip of only millimeters to a few square centimeters to achieve automation and high-throughput screening. … Continue Reading New ‘ELISA-on-a-chip’ set to revolutionise point-of-care testing.
Impaired activation of mitochondrial energy metabolism in the presence of glucose has been demonstrated in pancreatic beta-cells from patients with type 2 diabetes. The cause of this dysfunction has been … Continue Reading New diagnostic identifies mitochondria dysfunction in Type 2 diabetes.
A research group from Helmholtz Zentrum München has developed an assay whereby mini-breasts in-a-dish can be grown, with cultured human breast epithelial cells rebuilt into the three-dimensional tissue architecture of the … Continue Reading Researchers grow mini breast-in-a-dish, provide breakthrough in breast cancer proliferation.
A test that costs less than a $1 and yields results in minutes has been shown in newly published studies to be more sensitive and more exact than the current … Continue Reading Study finds $1 test using gold nanoparticles outperforms PSA screen for prostate cancer.
Telomeres are short stretches of repeated nucleotides that protect the ends of chromosomes. In somatic cells, these protective sequences become shorter with each cellular replication until a critical length is … Continue Reading Large scale human study shows longer telomere length leads to higher cancer mortality.
A team of researchers from Columbia University, Rwanda Biomedical Center, Centers for Disease Control and OPKO Diagnostics have developed a low-cost smartphone accessory that can perform a point-of-care test that simultaneously detects … Continue Reading Smartphone device is the first ever to replicate all functions of a lab-based blood test.
One of the roadblocks to the eradication of tuberculosis (TB) is the difficulty in identifying patients with latent TB infections. Neither the tuberculin skin test nor interferon-gamma release assays (IGRAs) … Continue Reading New whole blood assay is the first to identify latent TB infections.
A group of researchers from the University of Kentucky, Duke University and Max Planck Research have identified the receptors activated by two odours using a new method that tracks responses to … Continue Reading Researchers obtain the holy grail of odorant receptor identification.
Researchers from the Broad Institute of MIT and Harvard, Harvard Medical School, and Harvard-affiliated hospitals have uncovered an easily detectable, ‘pre-malignant’ state in the blood that significantly increases the likelihood … Continue Reading Two studies identify and verify a detectable, pre-cancerous state in the blood.
A study led by University of North Carolina researchers represents an important step forward in the accurate diagnosis of people who are experiencing the earliest stages of psychosis. Psychosis includes … Continue Reading Blood test may help determine who is at risk for psychosis.
A simple point-of-care testing device for anemia could provide more rapid diagnosis of the common blood disorder and allow inexpensive at-home self-monitoring of persons with chronic forms of the disease. … Continue Reading FDA-funded study for one-minute point-of-care anemia test shows promise.
A newborn screening test for severe combined immunodeficiency (SCID) reliably identifies infants with this life-threatening inherited condition, leading to prompt treatment and high survival rates, according to a study supported … Continue Reading Test reliably detects inherited immune deficiency in newborns.
The FDA has approved the world’s first zinc transporter 8 autoantibody (ZnT8Ab) test that can help determine if a person has type 1 diabetes and not another type of diabetes. … Continue Reading FDA approves world’s first ZnT8Ab autoantibody test to diagnose type 1 diabetes.
