(LOS ANGELES and CHICAGO) -- Cartilage is far from being like cartilage. As a rubber-like elastic tissue with widely varying properties, it lubricates our joints to keep them healthy and in motion, and forms many of our internal structures such as the intervertebral discs in our spine, the flexible connections between our ribs, and our voice box, as well as external tissues like nose, and ears.
What The Study Did: Reverse transcriptase-polymerase chain reaction tests were used to assess potential viral shedding among patients who previously had been diagnosed with and had clinically recovered from COVID-19.
Authors: Pa Wu, Ph.D., of the Hunan Normal University in Changsha, China, is the corresponding author.

A scientist at the University of Sydney has achieved what one quantum industry insider has described as "something that many researchers thought was impossible".
Dr Benjamin Brown from the School of Physics has developed a type of error-correcting code for quantum computers that will free up more hardware to do useful calculations. It also provides an approach that will allow companies like Google and IBM to design better quantum microchips.
Samuel Hulse, a Ph.D. candidate at UMBC, spent a lot of time in waders over the last two years. He traipsed from stream to stream across the eastern U.S., carefully collecting live specimens of small, colorful freshwater fish known as darters and taking photos of their habitats. Then he brought them back to the lab to capture high-quality images of their coloration patterns.
A research group including Professor OGAWA Wataru (Division of Diabetes and Endocrinology, Kobe University Graduate School of Medicine) and Project Associate Professor HOSOOKA Tetsuya (Division of Development of Advanced Therapy for Metabolic Disease, Kobe University Graduate School of Medicine) has clarified the mechanism underlying the development of diabetes and non-alcoholic steatohepatitis (NASH), a severe form of fatty liver.
In complex operations, is there a correlation between the volume of service provided per hospital and the quality of the treatment outcome? This question is addressed in eight commissions on minimum volumes that the Federal Joint Committee (G-BA) has issued to the Institute for Quality and Efficiency in Health Care (IQWiG). The IQWiG report is now available for the fifth intervention to be tested, kidney transplantation.
Take a look inside the cap of your favorite toothpaste, and you might see hard, white residue, a firm version of the smooth paste you squeeze onto your brush.
Many paste materials, also known as dense colloidal suspensions, stiffen as they age. Structural dynamics, or changes in the loads the materials undergo over time, are partly responsible for this change, but for decades, experts have suspected that there's more going on inside these materials.
For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.
A species of parasitic wasp discovered by chance could provide growers with a chemical-free way of controlling a major pest.
Researchers made the discovery when the wasps appeared mysteriously in colonies of cabbage stem flea beetles (CSFB) they were studying to test feeding preferences on oilseed rape.
The wasps appeared even though the beetles were confined to potted oilseed rape plants inside micro-perforated bags.
NASA's Aqua satellite used infrared light to provide forecasters with a look at the temperatures of the cloud tops in Tropical Storm Mangga.
Mangga, formerly known as 27S, is moving through the Southern Indian Ocean. Mangga was approaching the Cocos (Keeling) Islands, where a tropical cyclone warning was in effect on May 22.
A person who has a stroke that causes vision loss is often told there is nothing she can do to improve or regain the vision she has lost.
New research from the University of Rochester, published in the journal Brain, may offer hope to stroke patients in regaining vision.
A new study highlights the need to engage Indigenous communities in managing sea otter population recovery to improve coexistence between humans and this challenging predator.
The sea otters' recovery along the northwest coast of North America presents a challenge for coastal communities because both otters and humans like to eat shellfish, such as sea urchins, crabs, clams and abalone. Expanding populations of sea otters and their arrival in new areas are heavily impacting First Nations and Tribes that rely on harvesting shellfish.
Australian scientists have for the first time produced a new generation of experimental solar energy cells that pass strict International Electrotechnical Commission testing standards for heat and humidity.
The research findings, an important step towards commercial viability of perovskite solar cells, are published today in the journal Science.
Up to 220 million people worldwide, with approximately 94% of them in Asia, could be at risk of drinking well water containing harmful levels of arsenic, a tasteless, odorless and naturally occurring poison. The global scope of this persistent public health issue is revealed in a new study, in which researchers present the most accurate and detailed global prediction map of groundwater arsenic concentrations to date. It reveals previously unidentified areas of potential arsenic contamination, including parts of Central Asia and broad areas of the Arctic and sub-Arctic.
Mental health issues among police officers are a "substantial health concern," with around 1 in 4 potentially drinking at hazardous levels and around 1 in 7 meeting the criteria for post traumatic stress disorder and depression, finds a pooled data analysis of the available international evidence, published online in Occupational & Environmental Medicine.
