Research has found a proposal to regulate mining of Indigenous lands in Brazil's Amazon rainforest could affect more than 863,000 square kilometres of forest and harm the nation's economy.
Led by University of Queensland visiting PhD student Juliana Siqueira-Gay, an international collaboration has warned that President Jair Bolsonaro's 2020 bill to mine inside recognised Indigenous Lands would come at a cost.
"Brazil's Indigenous Lands are unbelievably valuable - socially, ecologically and economically," Ms Siqueira-Gay said.
Global maps of places where people and forests coexist show that an estimated 1.6 billion people live within 5 kilometers of a forest. The assessment, based on data from 2000 and 2012 and published September 18 in the journal One Earth, showed that of these 1.6 billion "forest-proximate people," 64.5 percent were located in tropical countries, and 71.3 percent lived in countries classified as low or middle income by the World Bank.
Astronomers using the National Science Foundation's Very Long Baseline Array (VLBA) have made the first direct geometric measurement of the distance to a magnetar within our Milky Way Galaxy -- a measurement that could help determine if magnetars are the sources of the long-mysterious Fast Radio Bursts (FRBs).
Free electron X-ray lasers deliver intense ultrashort pulses of x-rays, which can be used to image nanometer-scale objects in a single shot. When the x-ray wavelength is tuned to an electronic resonance, magnetization patterns can be made visible. When using increasingly intense pulses, however, the magnetization image fades away. The mechanism responsible for this loss in resonant magnetic scattering intensity has now been clarified.
Every day, we make hundreds of decisions. While most are small and inconsequential, like choosing what to eat or wear, others are more complex and involve weighing up potential costs and benefits, like deciding whether to study more for a better grade instead of hanging out with friends.
By André Julião | Agência FAPESP – Researchers at the University of São Paulo (USP) in Brazil have characterized a novel family of anti-bacterial toxins present in bacteria, including Salmonella enterica. This species uses toxic proteins to kill other bacteria in gut microbiota and facilitate colonization of the infected host’s gut.
The study is published in Cell Reports and featured on the cover of the journal.
HSE University researchers have confirmed that the level of phonological processing skills in children can impact their ability to master reading. Complex phonological tests are best suited to detect phonological impairment. The study was published on September 6, 2020, in the Journal of Research in Reading.
People who smoke are increasingly using e-cigarettes to try to quit smoking, a study by researchers at the University of Otago, Wellington, has found.
The researchers found that between 2016 and 2018 the level of awareness, as well as the use of e-cigarettes, increased among smokers and those who had recently quit smoking.
The principal investigator of the study, Professor Richard Edwards from the University's Department of Public Health, says e-cigarette use was most common among those aged 18-24 years and among those who had recently quit smoking.
Prices paid to hospitals nationally during 2018 by privately insured patients averaged 247% of what Medicare would have paid, with wide variation in prices among states, according to a new RAND Corporation study.
Some states (Arkansas, Michigan and Rhode Island) had relative prices under 200% of Medicare, while other states (Florida, Tennessee, Alaska, West Virginia and South Carolina) had relative prices that were above 325% of Medicare.
Ancient historiographers described steppe nomads as violent people dedicated to warfare and plundering. Little archaeological and anthropological data are however available regarding violence in these communities during the early centuries CE. In a new study in the American Journal of Physical Anthropology, an international team led by researchers from the University of Bern and the Russian Academy of Sciences presents new discoveries about the types of violence lived by nomads from Siberia between the 2nd-4th centuries CE.
Researchers from the Singapore University of Technology and Design (SUTD) developed a method to perform direct ink writing (DIW) 3D printing of milk-based products at room temperature, while maintaining its temperature sensitive nutrients.
A new study finds that glyphosate residue in manure fertilizer decrease the growth of strawberry and meadow fescue as well as runner production of strawberry.
Earlier experiments with Japanese quails showed how glyphosate residue in poultry feed accumulated in quail manure. In these experiments, half of the quails were fed with glyphosate-contaminated feed while the control group were fed with organic feed free from glyphosate residues. This allowed testing whether glyphosate residues in poultry manure affect crop plants if the manure is used as a fertilizer.
Through drawings, researchers from the University of Seville, the École Polytechnique Fédérale de Lausanne (Switzerland) and the University of Granada have identified details hitherto unknown in the muqarnas of the temples of the Lions' Courtyard at the Alhambra in Granada, a UNESCO World Heritage Site.
Tokyo, Japan -- Migraines affect millions of people worldwide, often lasting days and severely disrupting lives. More than simply super-intense headaches, some migraines actually result from pathological excitation of neurons in the brain. A new study in mice led by Kohichi Tanaka at Tokyo Medical and Dental University (TMDU) shows that susceptibility to migraines could be related to a molecular transporter that normally works to prevent excessive excitation of neurons.
An international effort that brought together more than 60 ice, ocean and atmosphere scientists from three dozen international institutions has generated new estimates of how much of an impact Earth's melting ice sheets could have on global sea levels by 2100. If greenhouse gas emissions continue apace, Greenland and Antarctica's ice sheets could together contribute more than 15 inches (38 centimeters) of global sea level rise - and that's beyond the amount that has already been set in motion by Earth's warming climate.
