When stay-at-home orders were announced as one of the greatest tools in our arsenal against the COVID-19 pandemic, anyone who's vintage enough to have watched forward-looking shows and movies-- from "The Jetsons" to "Star Trek" to "Back to the Future" -- might have thought America was ready to embrace a world where video calling and other tech-heavy communication options reigned supreme.
The global population is aging, and so are their eyes. In fact, the number of people with vision impairment and blindness is expected to more than double over the next 30 years.
A meta-analysis in The Lancet Global Health, consisting of 48,000 people from 17 studies, found that those with more severe vision impairment had a higher risk of all-cause mortality compared to those that had normal vision or mild vision impairment.
HOUSTON - (March 5, 2021) - Even a small effort up front can boost the abilities and confidence of girls as they anticipate taking challenging science courses.
A long-running summer program at Rice University and elsewhere that trains high school girls in basic physics concepts has proven successful in helping them thrive when they take on full courses the next year.
BUFFALO, N.Y. -- It looks like science fiction: A machine dips into a shallow vat of translucent yellow goo and pulls out what becomes a life-sized hand.
But the seven-second video, which is sped-up from 19 minutes, is real.
The hand, which would take six hours to create using conventional 3D printing methods, demonstrates what University at Buffalo engineers say is progress toward 3D-printed human tissue and organs -- biotechnology that could eventually save countless lives lost due to the shortage of donor organs.
Powerful new genetic engineering methods have given scientists the potential to revolutionize several sectors of global urgency.
Egg cells are by far the largest cells produced by most organisms. In humans, they are several times larger than a typical body cell and about 10,000 times larger than sperm cells.
There's a reason why egg cells, or oocytes, are so big: They need to accumulate enough nutrients to support a growing embryo after fertilization, plus mitochondria to power all of that growth. However, biologists don't yet understand the full picture of how egg cells become so large.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have studied the properties of mixtures of silicone-coated "magic sand", a popular kid's toy, and normal sand. Silicone-coated sand particles were found to interact with each other only, and not with other sand particles. The team discovered that adding silicone-coated sand beyond a certain threshold leads to an abrupt change in clustering and rigidity, a simple, useful way to potentially tune the flow of granular materials for industry.
Protein controlling magnesium identified as therapeutic target for non-alcoholic fatty liver disease
An international team of researchers has identified the CNNM4 protein as a key regulator of magnesium in the liver and potential therapeutic target for non-alcoholic fatty liver disease, according to a study published in the Journal of Hepatology.
Non-alcoholic steatohepatitis, a form of fatty liver disease characterized by inflammation and liver fibrosis, is associated with obesity and has a worldwide prevalence of 1.7 billion people.
An exquisitely detailed global ocean model simulation from the National Center for Atmospheric Research (NCAR) has given scientists rare insight into where baby sea turtles may go in their "lost years" after they scramble off the sandy beaches where they are born and swim into the open ocean.
Digital solutions including remote monitoring can help chronic pain sufferers manage their pain and reduce the probability of misuse of prescription opioids.
For chronic pain sufferers an app may be just the tool they need to manage their pain. In a UHN-led study that used the app "Manage My Pain" enrolled patients saw clinically significant reductions in key areas that drive increased medical needs, potential abuse of prescription opioids and of course, pain.
The human genome contains roughly three million letters. On average, the genome sequences of any two people differ from each other by about one in every 1,000 letters. Yet different variants occur, from substituted letters to entire missing sections of DNA. Scientists from the Berlin Institute of Health (BIH) and the Regensburg Center for Interventional Immunology (RCI) have teamed up with Icelandic researchers to develop software that reliably and quickly identifies large deletions in ten-thousands of genomes simultaneously.
Japanese researchers have developed a simulation method to theoretically estimate the performance of heterogeneous catalyst by combining first-principles calculation (1) and kinetic calculation techniques. Up to now, simulation studies mainly focused on a single or limited number of reaction pathways, and it was difficult to estimate the efficiency of a catalytic reaction without experimental information.
The speed at which we produce facial expressions plays an important role in our ability to recognise emotions in others, according to new research at the University of Birmingham.
A team in the University's School of Psychology carried out research which showed that people tend to produce happy and angry expressions more rapidly, while sad expressions are produced more slowly.
The vegan diet is on trend. How this type of diet affects health is the subject of scientific studies. In a new study from the German Federal Institute for Risk Assessment (BfR), the bone health of 36 vegans as well as 36 people following a mixed-food diet was determined with an ultrasound measurement of the heel bone. The result: on average, people following a vegan diet had lower ultrasound values compared to the other group. This indicates poorer bone health.
In order to show the clinical relevance of a difference between two treatment alternatives, in recent years, the manufacturer dossiers submitted in early benefit assessments of new drugs have increasingly contained responder analyses for patient-relevant outcomes. In such analyses, it is investigated whether the proportion of patients experiencing a noticeable change in the respective outcome differs between the two treatment groups in a study.
