The Food and Drug Administration says it will begin regulating laboratory-developed tests, a growing class of medical diagnostics that have never before been subject to federal oversight.
Researchers say they have discovered a chemical alteration in a single human gene linked to...
Scientists have linked more than 100 spots in our DNA to the risk of developing schizophrenia,...
Scientists have identified a set of 10 proteins in the blood which can predict the onset of Alzheimer’s, marking a significant step towards developing a blood test for the disease.
Located deep in the human gut, the small intestine is not easy to examine. Now, researchers are developing a new imaging technique involving nanoparticles suspended in liquid to form “nanojuice” that patients would drink.
3-D mammograms may be better at finding cancer than regular scans, a large study suggests, although whether that means saving more lives isn't known. The study involved almost half a million breast scans, with more than one-third of them using relatively new 3-D imaging along with conventional scans.
Stanford University researchers have devised a noninvasive way to detect heart-transplant rejection weeks or months earlier than previously possible. The test, which relies on the detection of increasing amounts of the donor’s DNA in the blood of the recipient, does not require the removal of any heart tissue.
Lung cancer causes more deaths in the U.S. than the next three most common cancers combined. The reason for the striking mortality rate is simple: poor detection. Lung cancer attacks without leaving any fingerprints, quietly afflicting its victims and metastasizing uncontrollably—to the point of no return. Now a new device may turn the tide by both accurately detecting lung cancer and identifying its stage of progression.
Improved diagnosis and management of one of the most common cancers in men- prostate cancer- could result from research, which has discovered that seminal fluid (semen) contains biomarkers for the disease.
A test that counts the number of locations in tumor specimens where tumor cells may invade blood vessels predicted the risk of distant spread, or metastasis, for the most common type of breast cancer.
Christofer Toumazou believes he can change the world with his “one chip, one bug – one chip, one drug,” slogan. Nominated for the European Patent Office’s 2014 European Inventor award, he holds a patent for the technology behind a microchip that can analyze DNA within 30 minutes and without a laboratory.
A sensor which can be used to screen for diabetes in resource-poor settings has been developed by researchers and tested in diabetic patients, and will soon be field tested in sub-Saharan Africa.
A multicenter team of researchers report that a commercial test designed to rule out the presence of genetic biomarkers of prostate cancer may be accurate enough to exclude the need for repeat prostate biopsies in many— if not most— men.
Scientists and physicians at UC San Francisco are leading a $26 million, multi-institutional research program in which they will employ advanced technology to characterize human brain networks and better understand and treat a range of common, debilitating psychiatric disorders.
Researchers have developed a new cognitive test that can better determine whether memory impairments are due to very mild Alzheimer’s disease or the normal aging process.
Researchers from The University of Texas at Dallas and the University of Tokyo have created electronic devices that become soft when implanted inside the body and can deploy to grip 3-D objects, such as large tissues, nerves and blood vessels. These biologically adaptive, flexible transistors might one day help doctors learn more about what is happening inside the body, and stimulate the body for treatments.
An app called DermoScreen, which would allow users to take a photo of a suspicious mole or lesion with your phone, run it through an embedded software program and find out within a few seconds if it is likely to be cancerous, is currently being evaluated for further testing.
Chromosomal abnormalities that result in birth defects and genetic disorders remain a significant health burden, as some prenatal screenings are a potential risk to mother and unborn child. Now, scientists are investigating a new sequencing procedure that can be completed without harm to mother or fetus.
A study of concussion patients using diffusion tensor imaging (DTI) found that males took longer to recover after concussion than females did. Results of the study also show that DTI can be used as a bias-free way to predict concussion outcome.
Researchers have established a technique that allows them to track neural communication in the brain over time, using magnetic resonance imaging (MRI) along with a specialized molecular sensor.
Federal health regulators have cleared a genetic test from Roche as a first-choice screening option for cervical cancer. It was a role previously reserved for the Pap smear, the decades-old mainstay of women's health.
Researchers have developed an ultrasound device that could help identify arterial plaque that is at high risk of breaking off and causing heart attack or stroke.
The process of metastasis is still poorly understood. Now, a research team has developed a simple test that can reveal the evolutionary relationships among various tumor sites within a patient, information that may someday help with treatment planning.
Scientists collaborated on the first large-scale investigation into the evolution of self-control in animals, defined in the study as the ability to inhibit powerful but ultimately counter-productive behavior.
Researchers used an MRI-based method to identify and confirm the presence of brown adipose tissue in a living adult, which could prove to be an essential step towards a new wave of therapies to aid the fight against diabetes and obesity.
Using just a single drop of blood, a team of UW-Madison researchers has developed a faster, cheaper and more accurate tool for diagnosing even mild cases of asthma. This handheld technology—which takes advantage of a previously unknown correlation between asthmatic patients and the most abundant type of white blood cells in the body—means doctors could diagnose asthma even if their patients are not experiencing symptoms during their visit.
Researchers have devised a way to quickly bring to the clinic the technique of using blood samples to diagnose many types of solid cancers, or to monitor the amount of cancer in a patient’s body and responses to treatment.
In a series of studies researchers have used specialized 3-D MRI scans to precisely measure living and dying tumor tissue to quickly show whether highly toxic chemotherapy is working.
