COLUMBIA, Mo. - When he was in middle school, teachers would give Sam Curran a list of words to type in a computer to practice his vocabulary. But Sam, who has autism, was unable to stay focused on the task and required a significant amount of one-to-one direction from a teacher to complete his work. After his mother, Alicia, persuaded his teachers to allow Sam to change the colors of the words, he was able to complete work more independently and began making remarkable progress.
Exactly what kills a person with COVID-19?
How do those deaths differ from the deaths of people whose lungs fail rapidly because of other infections or injuries?
And what can hospital teams pressed into service on overtaxed COVID-19 wards do to try to keep patients from dying, despite strained circumstances?
All of these questions have sparked discussion - and even conspiracy theories - since the pandemic began. Now, two studies from Michigan Medicine may help answer them.
A University of Saskatchewan study has found that the COVID-19 pandemic has led to significant worsening of already poor dietary habits, low activity levels, sedentary behaviour, and high alcohol consumption among university students.
Researchers led by Tokyo Medical and Dental University (TMDU) find that certain oral pathogens are more prevalent in esophageal cancer patients, and could be used as a novel diagnostic tool
Tokyo, Japan - It is increasingly clear that the trillions of bacteria that make themselves at home in and on the human body are more than just casual observers along for the ride. Gut bacteria in particular have been shown to have an enormous influence on human health, with studies suggesting they play a role in illnesses ranging from autoimmune disorders to anxiety and depression.
Dinitrogen (N2) fixation is considered as one of the most essential tasks in basic science, providing straightforward methods to produce ammonia and nitrogen-containing molecules. Exploring the reactivity of N2 units of transition metal-nitrogen complexes is of great significance and challenging in the chemistry. Since the first Ru-N2 complex was prepared in 1965, important progress has been made in the synthesis and reactivity of transition metal nitrogen complexes.
In a new study, an international research team led by Sebastian Stumpf from the University of Vienna describes an exceptionally well-preserved skeleton of the ancient shark Asteracanthus. This extremely rare fossil find comes from the famous Solnhofen limestones in Bavaria, which was formed in a tropical-subtropical lagoon landscape during the Late Jurassic, about 150 million years ago. The almost complete skeleton shows that Asteracanthus was two-and-a-half meters long in life, which makes this ancient shark one of the largest of its time.
A vector refers to an organism that carries and transmits an infectious disease, as mosquitoes do malaria.
Lead compounds are chemical compounds that show promise as treatment for a disease and may lead to the development of a new drug.
Antiplasmodial lead compounds are those that counter parasites of the genus Plasmodium, which is the parasite that infects mosquitoes and causes malaria in people.
The study findings were published in Nature Communications on 11 January 2021, at a time when malaria incidence generally peaks after the holiday season.
Recently, the innovation project watermelon and melon cultivation and physiology team of Zhengzhou Fruit Research Institute has made new progress in the metabolism regulation of sugar and organic acid in watermelon fruit. The changes of sugar and organic acid during the fruit development were analyzed and the key gene networks controlling the metabolism of sugar and organic acid during the fruit development were identified.
If you asked people which group of animals is the most abundant on earth, hardly anyone would know the right answer. Ants? Fish? No, and not humans either. The answer is nematodes, also known as roundworms. Four out of five animals on earth belong to this group, and the reason hardly anyone is aware of the fact is that they live underground, invisible to us. Together with thousands of other soil organisms, they quietly, discreetly and constantly perform enormously important services for the world above them.
Roughly 8,200 years ago, the island of Yuzhniy Oleniy Ostrov in Lake Onega in the Republic of Karelia, Russia, housed a large burial ground where men, women and children of varying ages were buried. Many of the graves contain an abundance of objects and red ochre, signifying the wish to ensure the comfort of the buried also after death. Pendants made of elk incisors were apparently attached to clothing and accessories, such as dresses, coats, cloaks, headdresses and belts.
When three galaxies collide, what happens to the huge black holes at the centers of each? A new study using NASA's Chandra X-ray Observatory and several other telescopes reveals new information about how many black holes are furiously growing after these galactic smash ups.
Astronomers want to learn more about galactic collisions because the subsequent mergers are a key way that galaxies and the giant black holes in their cores grow over cosmic time.
Scientists at the Walter Reed Army Institute for Research have shown that microRNA biomarkers related to Alzheimer's disease play a role in brain damage caused by traumatic brain injury.
Astronomers have curated the most complete list of nearby brown dwarfs to date thanks to discoveries made by thousands of volunteers participating in the Backyard Worlds citizen science project. The list and 3D map of 525 brown dwarfs -- including 38 reported for the first time -- incorporate observations from a host of astronomical instruments including several NOIRLab facilities. The results confirm that the Sun's neighborhood appears surprisingly diverse relative to other parts of the Milky Way Galaxy.
NEW YORK (January 14) -- A new study co-authored by researchers from the Wildlife Conservation Society's (WCS) Global Conservation Program and the University of British Columbia (UBC) Faculty of Forestry introduces a classification called Resistance-Resilience-Transformation (RRT) that enables the assessment of whether and to what extent a management shift toward transformative action is occurring in conservation.
A wide breadth of behaviors surrounding oral sex may affect the risk of oral HPV infection and of a virus-associated head and neck cancer that can be spread through this route, a new study led by researchers at the Johns Hopkins Kimmel Cancer Center suggests. These findings add nuance to the connection between oral sex and oropharyngeal cancer -- tumors that occur in the mouth and throat -- and could help inform research and public health efforts aimed at preventing this disease.
