Harvard scientists have investigated why we age, and how we could stop it. In tests in mice, the team showed that epigenetic “software glitches” drive the symptoms of aging – and a system reboot can reverse them, potentially extending lifespan.
-
Although there are now a number of skin-worn sensors which identify metabolites in sweat, the technology is limited in what it can detect, plus the sensors often aren't reusable. A new one, however, utilizes a "molecularly imprinted polymer" to be much more useful.
-
Sudden infant death syndrome (SIDS) is one of leading causes of infant death and a team of researchers in Australia have now identified the first blood biomarker linked to brain arousal that could potentially be used to identify infants most at risk.
-
Urine analysis may indeed be a valuable source of information on a patient's health, but arranging for samples to be taken and analyzed can be time-consuming. A new sensor could help, by allowing diapers to do the job on an ongoing basis.
-
Cancer treatments have better outcomes if the disease is caught early. A new Oxford study demonstrates an experimental blood test that shows promise in detecting a variety of cancers in patients, and even whether or not they’ve spread.
-
Glioblastoma is a brain cancer that can be aggressive and, unfortunately, tricky to diagnose without a biopsy. But a new noninvasive method, tested in mice and pigs, could one day diagnose the disease with ultrasound pulses and a basic blood test.
-
Blood samples taken from Russian cosmonauts before and after long stints on the ISS have revealed elevations of biomarkers that could indicate brain damage, adding to a growing body of research highlighting the deleterious effects of space travel.
-
New research from the Stanford University School of Medicine and the Buck Institute for Research on Aging is demonstrating a new tool that can calculate a person’s immune system age, which could help predict frailty and disease before symptoms appear.
-
New data from a preliminary trial testing a novel kind of brain cancer drug has found incredibly promising responses in a particular subset of patients. A Phase 2 trial is now underway concentrating on patients with a specific biomarker.
-
Researchers are closer to an objective blood test for mood disorders, with a new study describing a panel of blood-based biomarkers that can distinguish between depression and bipolar disorder, and measure the future risk of developing these conditions.
-
A brand new type of particle has been discovered in the human bloodstream. The sausage-shaped structures were first found by researchers at La Jolla Institute for Immunology in mice with sepsis, and they appear to be related to inflammatory disease.
-
Preliminary research has discovered several blood-based biomarkers which can specifically indicate stroke damage to brain tissue. The goal of the research is to develop a simple blood test to rapidly detect whether a patient is suffering a minor stroke.
