Nanolaser Can Perform Medical Procedures Without Damaging Tissue

Researchers have used novel materials to create a nanolaser that can function inside the human body without damaging healthy tissues. (Image source: Northwestern University) Researchers are eyeing next-generation, bio-compatible medical devices to perform complex procedures inside the human body without being majorly invasive. As part of this endeavor, researchers at Northwestern and Columbia Universities have developed a nanolaser that is they say is biocompatible and can function inside living tissues without harming them. The researchers published a paper on their work in the journal Nature Materials. The researchers envision their laser can be used not only for internal medical purposes such as targeted diagnosis and treatment of diseases such as cancer, but also as part of lab-on-a-chip schemes for fast and large-scale molecular characterization, sensing, and synthesis. There are two key aspects of the laser’s design: One is that the laser is comprised mostly of glass, which is an inherently biocompatible material. The other is that it can be excited with longer wavelengths of light and emit at shorter wavelengths. Moreover, the laser is just 50 to 150 nanometers thick, or about 1/1,000th the thickness of a single human hair. This means it can fit and function inside extremely confined spaces – including quantum circuits, microprocessors, and even living tissues, researchers said. Some of the tasks it might perform inside the human bo...

Our world has never witnessed a time of greater promise for improving human health. Many of today’s health advances have stemmed from a long arc of discovery that begins with strong, steady support for basic science. In large part because of fundamental research funded by the National Institutes of Health (NIH), which traces its roots to 1887, Americans are living longer, healthier lives. Life expectancy for a baby born in the U.S. has risen from 47 years in 1900 to more than 78 years today. Among the advances that have helped to make this possible are a 70% decline in the U.S. death rate from cardiovascular disease ...

HOLLISTON (CBS) – To spend time with Declan Vail is to experience an elevating joy. Whether he is plucking a guitar in his playroom, putting on a puppet show with his younger brother Teagan or riding in the back of a police car to the Dana Farber Jimmy Fund Clinic, he is the embodiment of happiness. And yet, this bubbly, outgoing three year-old is fighting a brain tumor. An inoperable brain tumor that has thrown his family’s life into–some degree of–chaos and uncertainty. “I think he has always been brave and strong but he is steadfast in it now,” his father, Jeremy told WBZ’s Lisa...

AbstractBackgroundThe high efficacy of targeted treatments in a- to oligosymptomatic non-small cell lung cancer (NSCLC) brain metastases (BM) revived the long discussion on BM screening. Therefore, we aimed to investigate the prognostic impact of symptomatic burden in patients with newly NSCLC BM in a large real-life cohort.MethodsPatients with newly diagnosed NSCLC BM were identified from the Vienna Brain Metastasis Registry.Results1531 patients (male 57.4%, female 42.3%; median age 62 years) were available for further analysis. Neurological symptoms including neurological deficits (952/153; 62.2%), symptoms of increased ...

You're reading 8 Nootropics to Stimulate Your Brain This Fall, originally posted on Pick the Brain | Motivation and Self Improvement. If you're enjoying this, please visit our site for more inspirational articles. Nootropics is a term coined by Dr. Corneliu E. Giurgea to describe a class of drugs, supplements, and other synthetic and naturally occurring compounds that improve cognitive function in our brains. They’re often called “smart drugs,” as they can help us think faster and more efficiently. Although used by pretty much everyone, these nootropic supplements are especially popular among youn...

Abstract Temporal lobe epilepsy (TLE) is the most common form of epilepsy characterized by spontaneous recurrent seizures. It has been widely accepted that individuals with TLE tend to have neuronal injuries and memory impairment. However, little is known about the underlying molecular mechanisms. MicroRNAs (miRNAs) are small noncoding RNAs that regulate the expression of target genes at the posttranscriptional level. An increasing body of evidence suggests that miRNAs play pivotal roles in the pathogenesis of epilepsy. Here, we sought to determine the role of miR-23a, one of the most common miRNAs involved in var...
