What The Study Did: This observational study estimates the 10-year risk for disease progression, surgery, metastasis, and cause-specific and all-cause mortality among African American men with low-risk prostate cancer managed with active surveillance.
A novel method to sample earwax could be a cheap and effective way to measure the hormone cortisol, according to a study led by researchers at UCL and King's College London.
The findings, published in the academic journal Heliyon, could point to new ways of monitoring depression and stress-linked conditions.
The new device can be used at home without clinical supervision, facilitating medical check-ups while maintaining social distancing due to COVID-19, and may also have the potential to measure glucose or COVID-19 antibodies that accumulate in earwax.
New findings from researchers at Washington University School of Medicine in St. Louis suggest the eye's cornea can resist infection from the novel coronavirus. Although the herpes simplex virus can infect the cornea and spread to other parts of the body in patients with compromised immune systems, and Zika virus has been found in tears and corneal tissue, SARS-CoV-2, the virus that causes COVID-19, does not appear to replicate in the human cornea.
Professor Xie Guangming's group in the College of Engineering at Peking University has found a simple yet previous unknown rule, explaining how do schooling fish save energy in collective motion. The related work has been published in Nature Communications.
Few beef producers in the temperate climate of southern Australia will have encountered the parasitic buffalo fly (Haematobia irritans exigua), a scourge of the cattle industry in the country's tropical and subtropical north - but maintaining this state of affairs, and also lifting a burden off the northern industry, has become a race against time, and climate.
Ants use their own acid to disinfect themselves and their stomachs. A team from Martin Luther University Halle-Wittenberg (MLU) and the University of Bayreuth has found that formic acid kills harmful bacteria in the animal's food, thereby reducing the risk of disease. At the same time, the acid significantly influences the ant's intestinal flora. The new study was published in the journal eLife.
Almost one in five patients with COVID-19 may only show gastrointestinal symptoms, according to a review of academic studies published in the journal Abdominal Radiology. The findings of the review suggest abdominal radiologists need to remain vigilant during the pandemic while imaging patients.
Since the latter half of the 20th century, vacationing has grown increasingly synonymous with tourism. This has been attributed to disposable incomes rising for many people, budget commercial airlines taking to the sky, and multitudes of tour facilitators entering the market, among other things. Now, economies of entire countries depend on tourism.
Prof. Dr. Thomas Kenkmann, geologist from the University of Freiburg's Institute of Earth and Environmental Sciences, together with mineralogist Prof. Dr. Wolf Uwe Reimold from the University of Brasilia, Brazil, and Dr. Manfred Gottwald from the German Aerospace Center (DLR) published an atlas providing a comprehensive overview of all known impact craters on every continent.
On a daily basis, and perhaps without realizing it, most of us are in close contact with advanced AI methods known as deep learning. Deep learning algorithms churn whenever we use Siri or Alexa, when Netflix suggests movies and tv shows based upon our viewing histories, or when we communicate with a website's customer service chatbot.
The proportion of those, who say that they meet less frequently with family or friends, rose from 65 to 76 percent. Furthermore, 69 percent say, they leave their home less - an increase by 10 percentage points. "With the current increase in the number of infections, people in Germany are becoming more cautious again," comments BfR-President Professor Dr. Dr. Andreas Hensel on the latest developments.

In Alzheimer's disease, a protein (peptide) forms clumps in the brain and causes sufferers to lose their memory. In a recently published article, a research group at Uppsala University described a new treatment method that increases the body's own degradation of the building blocks that lead to these protein clumps.
In the condition known as cavernoma, lesions arise in a cluster of blood vessels in the brain, spinal cord or retina. Researchers from Uppsala University can now show, at molecular level, that these changes originate in vein cells. This new knowledge of the condition creates potential for developing better therapies for patients. The study has been published in the journal eLife.
How can new life forms that we cannot see be discovered? Using a novel method based on looking for DNA in soil samples, researchers at Uppsala University have revealed the existence of two hitherto unknown, but very common fungus species. They are thought to perform a key function in the ecosystem, but their exact role remains to be clarified. The study is published in the journal IMA Fungus.
The oil from wild olive trees has excellent sensorial, physicochemical and stability characteristics from a nutritional point of view, according to an article published in the journal Antioxidants. The study, based on the analysis of fruits from wild olive trees of the natural reserve of the Medes islands (Catalonia), reveals that the parameters of the quality of oil are within the values the International Olive Council allowed.
