Scientists at the U.S. Department of Energy's Ames Laboratory have discovered an earlier unknown discontinuous magnetoelastic transition in a rare-earth intermetallic. The mechanism of the material's changing magnetic state is so unusual, it provides new possibilities for discovery of similar materials.

Materials that possess magnetoelastic phase transitions are highly sought after for a number of developing technologies, including caloric heating and cooling systems. Materials that display this property are rare, and are thought to be exclusively transition metal-based.

Alexandria, Va., USA - At the 96th General Session of the International Association for Dental Research (IADR), held in conjunction with the IADR Pan European Regional (PER) Congress, Yao Liu, China Medical University, Taiwan, Province of China gave an oral presentation titled "PD-1 is Required to Dental Pulp Stem Cell Properties." The IADR/PER General Session & Exhibition is in London, England at the ExCeL London Convention Center from July 25-28, 2018.

'Traffic jams' can also occur in the brain and they can be damaging. Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have been able to confirm that this is the case. They have been able to prove that disrupted transportation routes in nerve cells are a significant cause of Parkinson's disease.

Two years after a CIRES and CU Boulder team discovered a previously unknown class of waves rippling continuously through the upper Antarctic atmosphere, they've uncovered tantalizing clues to the waves' origins. The interdisciplinary science team's work to understand the formation of "persistent gravity waves" promises to help researchers better understand connections between the layers of Earth's atmosphere--helping form a more complete understanding of air circulation around the world.

Infrared satellite imagery provides temperature data, and when NASA's Aqua satellite passed over Tropical Storm Wukong, the coldest cloud tops circling the center resembled a strawberry and leaf.

Cloud top temperatures determine strength of the thunderstorms that make up a tropical cyclone. The colder the cloud top, the stronger the uplift in the storm that helps thunderstorm development. Basically, infrared data helps determine where the most powerful storms are within a tropical cyclone.

Using an advanced, new microscopy technique that can visualize chemical reactions occurring in liquid environments, researchers have discovered a new reason lithium-oxygen batteries -- which promise up to five times more energy than the lithium-ion batteries that power electric vehicles and cell phones -- tend to slow down and die after just a few charge/discharge cycles. They report their findings in the journal Nano Energy.

Sometimes, knowing who wins and who loses is more important than how the game is played.

In a paper published this week in Science Advances, researchers from the Santa Fe Institute describe a new algorithm called SpringRank that uses wins and losses to quickly find rankings lurking in large networks. When tested on a wide range of synthetic and real-world datasets, ranging from teams in an NCAA college basketball tournament to the social behavior of animals, SpringRank outperformed other ranking algorithms in predicting outcomes and in efficiency.

The bad news: Dust from the Sahara Desert in Africa - totaling a staggering 2 to 9 trillion pounds worldwide - has been almost a biblical plague on Texas and much of the Southern United States in recent weeks. The good news: the same dust appears to be a severe storm killer.

Highlights

Among individuals with autosomal dominant polycystic kidney disease, those who were treated with tolvaptan for up to 11 years had a slower rate of kidney function decline compared with historical controls.

Annualized kidney function decline rates of tolvaptan-treated patients did not change during follow-up.

Bottom Line: Analysis of cancer death data from 2008-2014 in New York state revealed high cancer mortality rates among U.S.-born blacks and Puerto Ricans and relatively low cancer mortality rates among Hispanic South Americans and Asians.

Journal in Which the Study was Published: Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Author: Paulo Pinheiro, MD, cancer epidemiologist at the Sylvester Comprehensive Cancer Center, University of Miami Miller School of Medicine.

A new study from the University of Waterloo has found that in some ways, the older you get the worse your decision making becomes.

The study established that younger children seem to make slightly better decisions than older children. The older children get, the more they tend to ignore some of the information available to them when making judgements, which though efficient can also lead to mistakes.

Cities can serve as useful proxies to study and predict the effects of climate change, according to a North Carolina State University research review that tracks urbanization's effects on plant and insect species.

Cities often display many of the predicted effects of climate change, including higher temperatures, higher carbon dioxide concentration and higher drought rates. Some of those effects are due to impermeable building materials like concrete and glass, which help create "urban heat islands" and prevent water from soaking into soil.

Imagine adapting to life in the U.S. after emigrating from Mexico. With so many confusing new processes and systems to navigate, how would you begin to understand something as complex as local and national politics? According to San Francisco State University Associate Professor of Political Science Marcela García-Castañon, who studies political socialization, you'd likely turn to your spouse.

A long-term plan to preserve the Rimatara lorikeet by restoring an extirpated population of the species on a neighboring island that is free of predatory ship rats is demonstrating the importance of this kind of protective program for the sustainability of endangered bird species. A case study published in the International Union for Conservation of Nature (IUCN) report Global Reintroduction Perspectives: 2018--Case Studies from Around the Globe sums up the results of an effort that began in 2000.
