3D nano-inks push industry boundaries
Mechanical engineering researchers at Michigan Technological University have created a way to make a 3D-printable nanocomposite polymeric ink that uses carbon nanotubes (CNTs) — known for their high tensile strength and lightness. This revolutionary ink could replace epoxies — and understanding why its properties are so fantastic is a first step toward its mass use. […]
Lab grown tumor models could improve treatment for pancreatic cancer
An international team of scientists have created a three-dimensional (3D) pancreatic cancer tumour model in the laboratory, combining a bioengineered matrix and patient-derived cells that could be used to develop and test targeted treatments. In a new study published today in Nature Communications, researchers from the University of Nottingham, Queen Mary University of London, Monash […]
Doctors Warn Of Future Disease Outbreaks As Kids’ Vaccination Rates Drop
Routine vaccination rates for children have significantly dropped since the start of the coronavirus pandemic, leading doctors to worry that there could be outbreaks of vaccine-preventable diseases, including ones that carry more risk to children than COVID-19. The number of routine vaccines distributed through the Centers for Disease Control and Prevention’s Vaccines for Children program — which provides immunizations […]
New machine learning method to analyze complex scientific data of proteins: Method allows faster and more accurate data analysis from NMR spectrometers
Scientists have developed a method using machine learning to better analyze data from a powerful scientific tool: nuclear magnetic resonance (NMR). One way NMR data can be used is to understand proteins and chemical reactions in the human body. NMR is closely related to magnetic resonance imaging (MRI) for medical diagnosis. NMR spectrometers allow scientists […]
What Are the Long-Term Side Effects of Rheumatic Fever? Complications
If not promptly treated, rheumatic fever can have long-term side effects such as rheumatic heart disease, which weakens the valves between the heart’s chambers. The majority of rheumatic fever (RF) symptoms go away after a few weeks or months, but recurrence and certain complications are common. Usually, heart and joint ailments are long-term consequences of […]
COVID Deaths Surpass 1918 Flu Deaths
U.S. COVID-19 deaths have now surpassed the 675,000 estimated deaths that occurred during the H1N1 influenza pandemic of 1918, but SARS-CoV-2 hasn’t exacted as heavy a toll as that pandemic. With a national population of around 103 million people at that time — about a third of the current total of 330 million Americans — […]
Time until dementia symptoms appear can be estimated via brain scan: Alzheimer’s dementia predicted by brain amyloid levels, age
Researchers at Washington University School of Medicine in St. Louis have developed an approach to estimating when a person who is likely to develop Alzheimer’s disease, but has no cognitive symptoms, will start showing signs of Alzheimer’s dementia. The algorithm, available online in the journal Neurology, uses data from a kind of brain scan known […]
Six stages of engagement in ADHD treatment revealed in new, diverse study
Six stages of engagement in treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) have been reported by researchers at Boston Medical Center based on a diverse study, inclusive of parents of predominantly racial and ethnic minority children with ADHD. Published in Pediatrics, this new framework has been informed by the experiences of parents throughout the various stages that […]
More Than a Nursing Shortage: A ‘Skills Gap’, Too
During the fourth wave of the COVID-19 pandemic, hospitals have closed beds, shut down elective surgeries, and called in federal assistance due to a shortage of a critical healthcare resource — nurses. Shortages of nurses and other healthcare workers are plaguing hospitals throughout the U.S., especially those in COVID hotspots. Mississippi has 2,000 fewer nurses […]
New technology designed to genetically control disease-spreading mosquitoes: CRISPR-based system developed to safely restrain mosquito vectors via sterilization
Leveraging advancements in CRISPR-based genetic engineering, researchers at the University of California San Diego have created a new system that restrains populations of mosquitoes that infect millions each year with debilitating diseases. The new precision-guided sterile insect technique, or pgSIT, alters genes linked to male fertility — creating sterile offspring — and female flight in […]
