Engineers at the University of California San Diego have developed a miniature, ultra-low power injectable biosensor that could be used for continuous, long-term alcohol monitoring. The chip is small enough to be implanted in the body just beneath the surface of the skin and is powered wirelessly by a wearable device, such as a smartwatch or patch.
SAN FRANCISCO, CA--April 10, 2018--Over a decade ago, Shinya Yamanaka and Kazutoshi Takahashi made a discovery that would revolutionize biomedical research and trigger the field of regenerative medicine. They learned how to reprogram human adult cells into cells that behave like embryonic stem cells. Scientists were shocked that something so complex could be done so simply, and they had thousands of questions.
Many mammals consume blood as part of their diet, but blood is actually a pretty poor source of energy. Only bats (order Chiroptera) include species that feed exclusively on blood.
So how do vampire bats manage to survive on such low-grade nourishment? A recently published article in Nature Ecology & Evolution provides part of the answer. The bats had to evolve in tandem with their microorganisms.
Targeted treatments have revolutionized care for lung cancer patients whose tumors harbor ALK or ROS1 alterations. Basically, cancers may use these genetic changes to drive their growth, but also become dependent on the action of these altered genes for their survival. Targeted treatments like crizotinib block the actions of ALK and ROS1, thus killing cancers that depend on them. However, when doctors target ALK or ROS1, cancers often evolve new ways to survive. After a period of success, targeted treatments against ALK+ and ROS1+ lung cancers often fail.
Researchers have identified specific predictive biomarkers that could help assess the level of risk for recurrence in patients with malignant glioma. The study, led by Henry Ford Health System's Department of Neurosurgery and Department of Public Health Sciences, was published today in Cell Reports.
Scientists have decoded faint distortions in the patterns of the universe's earliest light to map huge tubelike structures invisible to our eyes - known as filaments - that serve as superhighways for delivering matter to dense hubs such as galaxy clusters.
WASHINGTON D.C. -- Glaciers in Alaska's Denali National Park are melting faster than at any time in the past four centuries because of rising summer temperatures, a new study finds.
WASHINGTON -- Women with polycystic ovary syndrome (PCOS), the most common hormone condition among young women, are prone to mental health disorders, and their children face an increased risk of developing attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
New research, published in PLOS Medicine, conducted by researchers at the University of Liverpool, Imperial College London, Friedman School of Nutrition Science and Policy at Tufts and collaborators as part of the Food-PRICE project, highlights the potential health and economic impact of the United States (US) Food and Drug Administration's proposed voluntary salt policy.
ANN ARBOR--The child welfare system is more likely to intervene in households in "less neighborly" neighborhoods and in which parents spank their kids, a new study shows.
Researchers at the University of Michigan and Michigan State University conducted analyses on nearly 2,300 families from 20 large U.S. cities who responded to surveys and interviews. Participating families had a child who was born between 1998-2000.
The research community now has a new framework toward developing a biologically-based definition of Alzheimer's disease. This proposed "biological construct" is based on measurable changes in the brain and is expected to facilitate better understanding of the disease process and the sequence of events that lead to cognitive impairment and dementia.
Chicago, April 10, 2018 - "NIA-AA Research Framework: Towards a Biological Definition of Alzheimer's Disease" was published today in the April 2018 issue of Alzheimer's & Dementia: The Journal of the Alzheimer's Association. First author Clifford R. Jack, Jr., M.D., of Mayo Clinic Rochester, MN and colleagues propose shifting the definition of Alzheimer's disease in living people - for use in research - from the current one, based on cognitive changes and behavioral symptoms with biomarker confirmation, to a strictly biological construct.
A new way to rapidly assess levels of consciousness in people with head injuries could improve patient care.
The new score - based on the Glasgow Coma Scale - could also help doctors assess the health of the patient's central nervous system in cases of serious trauma or intensive care.
Using it could improve the way doctors around the world care for patients in a coma from brain injury.
The Glasgow Coma Scale (GCS), which was created at the University of Glasgow and the city's Southern General Hospital in 1974.
A new study in SLEEP, published by Oxford University Press, indicates that delaying school start times results in students getting more sleep, and feeling better, even within societies where trading sleep for academic success is common.
The study aimed to investigate the short and longer-term impact of a 45-min delay in school start time on sleep and well-being of adolescents.
When listening to a speaker, we often feel that we know what the speaker will say next. How is this possible? It is assumed that our brain routinely uses clues within a sentence to estimate the probability of upcoming words. Activating information about a word before it appears helps to rapidly integrate its meaning, once it appears, with the meaning of the sentence.
