In the first national study of its size, researchers at University of California San Diego School of Medicine and UC San Diego Health, Department of Nursing, have found that male and female nurses are at higher risk of suicide than the general population. Results of the longitudinal study were published in the February 3, 2020 online edition of WORLDviews on Evidence Based-Nursing.
Urbana, IL -- Fundamental research in condensed matter physics has driven tremendous advances in modern electronic capabilities. Transistors, optical fiber, LEDs, magnetic storage media, plasma displays, semi-conductors, superconductors--the list of technologies born of fundamental research in condensed matter physics is staggering. Scientists working in this field continue to explore and discover surprising novel phenomena that hold promise for tomorrow's technological advances.
An international study by Monash University has discovered wild grey seals can clap their flippers underwater during breeding season.
This is regarded as a show of strength that warns off competitors and advertises themselves to potential mates.
The video footage taken by researchers shows a male grey seal clapping in the wild, producing a gunshot-like 'crack'.
Marine mammals like whales and seals usually communicate vocally using calls and whistles.
A novel approach to reverse the progression of healthy cells to malignant ones may offer a more effective way to eradicate colorectal cancer cells with far fewer side effects, according to a team of researchers based in South Korea.
Colorectal cancer, or cancer of the colon, is the third most common cancer in men and the second most common in women worldwide. South Korea has the second highest incident rate of colorectal cancer in the world, topped only by Hungary, according to the World Cancer Research Fund.
There is a constant spring-cleaning in our cells: The cell's own recycling system, so-called autophagy, fills garbage bags with cellular waste, transports them to the recycling yard and makes the decomposed material available again. Researchers from the Max Planck Institute for Biology of Ageing in Cologne, Germany, have now been able to show in the model organism yeast that the membrane of the garbage bags, known as autophagosomes, is newly produced on the spot around the garbage and not built of already existing components.
Vast amounts of valuable energy, agricultural nutrients, and water could potentially be recovered from the world's fast-rising volume of municipal wastewater, according to a new study by UN University's Canadian-based Institute for Water, Environment and Health (UNU-INWEH).
Today, some 380 billion cubic meters (m3 = 1000 litres) of wastewater are produced annually worldwide - 5 times the amount of water passing over Niagara Falls annually - enough to fill Africa's Lake Victoria in roughly seven years, Lake Ontario in four, and Lake Geneva in less than three months.
TROY, N.Y. -- A newly identified compound is a promising candidate for inhibiting the production of amyloids, the abnormal proteins that form toxic clumps, called fibrils, inside the brains of patients with Alzheimer's disease. As published today in the Royal Society of Chemistry's Chemical Communications, the compound -- known as "C1" -- uses a novel mechanism to efficiently prevent the enzyme gamma-secretase from producing amyloids.
Montreal, February 3, 2020 -- Most people living with HIV control the virus thanks to antiretroviral therapy (ART). Although this medication is highly effective, the presence of latent viral reservoirs in their bodies means they require lifelong therapy. Studies have demonstrated that immunotherapy combining two anti-HIV antibodies can also suppress HIV, similar to ART.
Bacteria in our environment can be difficult to study: They are tiny and often live under conditions hard to recreate in the lab, for example in the deep sea or as symbionts in an animal host (or both, as the symbiotic bacteria in the present study). Investigations of the bacterial genome tell us what the microbes are theoretically capable of. What they actually do, however, is not revealed. Thus, scientists study the so-called metabolome of the bacteria: It comprises every metabolite the cells produce or consume, for example proteins, sugars or fats.
A study at The University of Texas MD Anderson Cancer Center showed that circulating tumor cells (CTCs), a form of liquid biopsy, was independently associated with melanoma relapse, suggesting CTC assessment may be useful in identifying patients at risk for relapse who could benefit from more aggressive therapy following primary treatment.
