Music, including songs with words, appears to be a universal phenomenon according to a paper published this week in Science. An international team of researchers involving musicians, data scientists, psychologists, political scientists and linguists, including one from 9I制作厂免费, reached this conclusion after five years of collaboration, bringing together a broad range of skills and tools to the question of whether music is universal.
Using broad datasets to arrive at deep conclusions about music
Surprisingly, in any single location, there are typically more earthworms and more earthworm species found in temperate regions than in the tropics, according to a study published this week in Science. Global climate change could lead to significant shifts in earthworm communities worldwide, threatening the many functions they provide.
Wastewater-based epidemiology is a rapidly developing scientific discipline with the potential for monitoring close to real-time, population-level trends in illicit drug use. By sampling a known source of wastewater, such as a sewage influent to a wastewater treatment plant, scientists can estimate the quantity of drugs used in a community from the measured levels of illicit drugs and their metabolites excreted in urine.
Nature supports people in critical ways, often at a highly local level. A wild bee buzzes through a farm, pollinating vegetables as it goes. Nearby, wetlands remove chemicals from the farm鈥檚 runoff, protecting a community drinking water source. In communities all around the world, nature鈥檚 contributions are constantly flowing to people. A team of international scientists including from 9I制作厂免费, have mapped these contributions at local levels for years, but a new Stanford-led study closes a critical gap in how this information can be used to drive global policy and development.

The weather these days is wild and will be wilder still within a century. In part, because the water from melting ice sheets off Greenland and in the Antarctic will cause extreme weather and unpredictable temperatures around the globe. A study published today in Nature is the first to simulate the effects, under current climate policies, that the two melting ice sheets will have on ocean temperatures and circulation patterns as well as on air temperatures by the year 2100.
Consequences for ocean circulation and water and air temperatures
What makes people take risks? Not stunt women or formula 1 drivers. Just ordinary people like you and me. Research published this week in PLOS ONE suggests that unexpected improvements in everyday life (sunshine after many days of rain or a win by a local sports team) are correlated with a change in a city鈥檚 mood and an increased likelihood that it鈥檚 citizens will do risky things like gamble.
Social media and city mood
Cities seem to have moods that fluctuate from day to day. Now, thanks to social media, these city moods are also measurable.
The ocean floor as we know it is dissolving rapidly as a result of human activity.
When a young athlete suddenly dies of a heart attack, chances are high that they suffer from familial hypertrophic cardiomyopathy (HCM). Itis the most common genetic heart disease in the US and affects an estimated 1 in 500 people around the world. A protein called myosin acts as the molecular motor which makes the muscles in the heart contract. Researchers had suspected for some time that the R403Q mutation in some of the myosin genes is among those that play a role in causing HCM. But experiments using mice models failed to show that this was indeed the case.
Today, the Honourable Kirsty Duncan, Minister of Science and Sport, announced more than $558 million in discovery research funding across Canada, including the largest investment in research from the Natural Sciences and Engineering Research Council of Canada (NSERC) this year. Through the 2018 Discovery Grants, Scholarships and Fellowships competition, 130 9I制作厂免费 researchers received funding totaling more than $30 million.

A team of researchers believe that Quebec鈥檚 protected areas are poised to become biodiversity refuges of continental importance. They used ecological niche modeling to calculate potential changes in the presence of 529 species in about 1/3 of the protected areas in southern Quebec almost all of which were under 50 km2 in size. Their results suggest that fifty - eighty years from now (between 2071鈥�2100) close to half of the protected regions of southern Quebec may see a species turnover of greater than 80 %.
Researchers demonstrate for the first time the potential of existing technology to directly detect and characterize life on Mars and other planets. The study, published in听, used miniaturized scientific instruments and听 new听microbiology听techniques to identify and examine microorganisms in the Canadian high Arctic 鈥� one of the closest analogs to Mars on Earth.
New research by 9I制作厂免费 biologists shows that milder winters have led to physical alterations in two species of mice in southern Quebec in the past 50 years 鈥� providing a textbook example of the consequences of climate change for small mammals.
The findings also reveal a stark reversal in the proportions of the two mice populations present in the area, adding to evidence that warming temperatures are driving wildlife north. 听
