Annual European Congress of Rheumatology

Madrid, Spain, 12-15 June 2019

Madrid, Spain, 13 June 2019: The results of a study presented today at the Annual European Congress of Rheumatology (EULAR 2019) demonstrate reduced risk of venous thromboembolism and persistent pain, but increased risk of revision in partial versus total knee replacement in patients with osteoarthritis.1

Researchers at the Institute for Integrated Cell-Material Sciences at Kyoto University have made a popular type of dye-sensitized solar cell more efficient by adjusting and updating their structure. Published in the Journal of the American Chemical Society (JACS), the team report a series of adaptations with a power conversion efficiency of 10.7%, the highest yet for this kind of dye-sensitized solar cell, the most efficient solar technology available at present.

A person's body composition could influence the difference between the amount of energy they spend while sitting versus standing, according to new research published in the open-access journal PLOS ONE. Conducted by Francisco J. Amaro-Gahete of the University of Granada, Spain, and colleagues, this work adds to mounting evidence that more energy is expended while standing than while sitting or lying down.

The diversity and availability of pollen foraged by honey bees across urban and suburban areas in the US varies drastically with the seasons, according to a study published June 12, 2019 in PLOS ONE by Juliana Rangel from Texas A&M University, USA, and colleagues.

HOUSTON -- (June 12, 2019) -- Using rare oxygen molecules trapped in air bubbles in old ice and snow, U.S. and French scientists have answered a long-standing question: How much have "bad" ozone levels increased since the start of the Industrial Revolution?

"We've been able to track how much ozone there was in the ancient atmosphere," said Rice University geochemist Laurence Yeung, the lead author of a study published online today in Nature. "This hasn't been done before, and it's remarkable that we can do it at all."

A new study from researchers at the Woods Hole Oceanographic Institution (WHOI) and Harvard University may help settle a long-standing question--how small amounts of organic carbon become locked away in rock and sediments, preventing it from decomposing. Knowing exactly how that process occurs could help explain why the mixture of gases in the atmosphere has remained stable for so long, says lead author Jordon Hemingway, a postdoctoral researcher at Harvard and former student at WHOI. The paper publishes June 14 in the journal Nature.

Visible imagery from NASA's Aqua satellite showed Tropical Cyclone Vayu has a compact central dense overcast cloud cover. Vayu's center was off-shore from India's Gujarart coast.

WASHINGTON -- Coral reefs around the world face growing danger from a changing climate, on top of the historic threats from local pollution and habitat destruction. In response, scientists are researching new interventions that have the potential to slow coral reef damage from warming and acidifying oceans. The interventions span a wide range of physical and biological approaches for increasing the stability of coral reefs, but they have only been tested at small scales.

Water is so commonplace that we often take it for granted. But too much - or too little of it - makes headlines.

Catastrophic flooding in the U.S. Midwest this spring has caused billions of dollars in damage and wreaked havoc with crops, after rain tipped off a mass melting of snow. Seven years of California drought so debilitating that it led to water rationing came to a close after a wet and snowy winter capped off several years of slow rebound and replenished the vital mountain snowpack.

Scientists at the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences have developed a chemocatalytic approach to convert cellulose into ethanol in a one-pot process by using a multifunctional Mo/Pt/WOx catalyst. This approach opens up an alternative avenue for biofuel production. The findings were published in Joule.

Cellulosic ethanol is one of the most important biofuels, yet commercial production is hindered by the low efficiency and high cost of the bioconversion process.

Foods that look the same on nutrition labels can have vastly different effects on our microbiomes, report researchers in a paper publishing June 12 in the journal Cell Host & Microbe. The researchers' observations of participants' diets and stool samples over the course of 17 days suggested that the correlation between what we eat and what's happening with our gut microbes might not be as straightforward as we thought. This adds an increased level of complexity to research focused on improving health by manipulating the microbiome.

Tremendous progress of organic solar cells (OSCs) has been exemplified by the use of non-fullerene electron acceptors (NFAs) in the past few years. Compared with fullerene derivative acceptors, NFAs show a multitude of advantages including tunable energy levels, broad absorption spectrum and strong light absorption ability, as well as high carrier mobility.

Balance is the key.

It's not exactly neuroscience; except that it is.

Since balance is key for almost everything we do--walking, cycling, and a million other things in life--it really is no surprise that electrical balance holds the key to understanding how our brains function.

MASCARA-2B/KELT-20b is an ultra hot Jupiter. It belongs to a new group of exoplanets, the hottest known until now, which can reach temperatures at the surface of over 2,000 K. The reason for its high temperature is the proximity of its orbit around its host star, causing it to receive a large flux of radiation in the upper layers of its atmosphere.

Monkeys living in South America are highly vulnerable to climate change and face an "elevated risk of extinction", according to a new University of Stirling-led study.

The research, involving an international team of scientists, found that a large percentage of non-human primates - including monkeys, lemurs and apes - are facing substantial temperature increases and marked habitat changes over the next 30 years.
