Encouraging activity and improving diet in children is crucial to cut deaths from cardiovascular disease – and is the focus of an innovative school project in São Paulo, Brazil. The first results are presented today at the Brazilian Congress of Cardiology (SBC 2019). The annual congress of the Brazilian Society of Cardiology (SBC) is being held from September 20 to 22, 2019, in Porto Alegre. The European Society of Cardiology (ESC) is holding scientific sessions in collaboration with the SBC as part of the ESC Global Activities program....

The migratory routes of a small seabird: Bulwer’s petrel can fly more than 1,800 kilometers over ocean waters to find food. The Bulwer’s petrel reaches more than 1,800 kilometers (~1,100 miles) from the Canary archipelago up to the Azores on its route in search of food, according to data from a new scientific monograph based on the studies carried out from 2010 to 2018 by the Research Group of Ecology of Marine Birds of the Faculty of Biology and the Biodiversity Research Institute of the University of Barcelona (IRBio), under the supervision of Professor Jacob González-Solís....

During the flight test, engineers intend to learn as much as possible about Orion’s performance. They are focused on the primary objectives for the mission: demonstrating Orion’s heat shield at lunar return re-entry conditions, demonstrating operations and facilities during all mission phases, and retrieving the spacecraft after splashdown. Seen here is the Orion capsule’s first look back at Earth for the Artemis I mission. The Space Launch System rocket and the Orion spacecraft launched at 1:47 a....

While many techniques can measure these processes among tens of thousands of cells, researchers have been unable to measure them at the single-cell level. Researchers at the University of Chicago’s Pritzker School of Molecular Engineering and Biological Sciences Division have developed a combined imaging and machine learning technique that can, for the first time, measure a metabolic process at both the cellular and sub-cellular levels. Using a genetically encoded biosensor paired with artificial intelligence, the researchers were able to measure glycolysis, the process of turning glucose into energy, of single endothelial cells, the cells that line blood vessels....

Direct geological evidence of recent volcanic activity has been observed on the surface of Venus for the first time. Scientists made the discovery after poring over archival radar images of Venus taken more than 30 years ago, in the 1990s, by NASA’s Magellan mission. The images revealed a volcanic vent changing shape and increasing significantly in size in less than a year. Scientists study active volcanoes to understand how a planet’s interior can shape its crust, drive its evolution, and affect its habitability....

Super-eruptions happen when enormous magma accumulations deep in the Earth’s crust, created over millions of years, travel quickly to the surface shattering pre-existing rock, according to recent research from the University of Bristol and Scottish Universities Environmental Research Centre. An international team of scientists was able to demonstrate, using a model for crustal flow, that pre-existing plutons—bodies of intrusive rock made from solidified magma or lava—were formed over a few million years prior to four known enormous super-eruptions and that the disruption of these plutons by newly emplaced magmas occurred extremely quickly....

Should climate change trigger the upsurge in heat and rainfall that scientists predict, people may face a threat just as perilous and volatile as extreme weather — each other. Researchers from Princeton University and the University of California-Berkeley report in the journal Science that even slight spikes in temperature and precipitation have greatly increased the risk of personal violence and social upheaval throughout human history. Projected onto an Earth that is expected to warm by 2 degrees Celsius by 2050, the authors suggest that more human conflict is a likely outcome of climate change....

Other than a spicy night snack, the crayfish has been endowed with greater significance. Prof. ZHU Xifeng’s team from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) made it possible to use crayfish shell as the biological template for high-performance supercapacitors. This work was published in Carbon. Compared with other high-performance materials, biomass has long been regarded as a promising one for its environmental-friendliness and extensive resources....

For the first time, researchers have captured images of the formation of individual viruses, offering a real-time view into the kinetics of viral assembly. The research provides new insights into how to fight viruses and engineer self-assembling particles. The research is published in the Proceedings of the National Academy of Sciences. “Structural biology has been able to resolve the structure of viruses with amazing resolution, down to every atom in every protein,” said Vinothan Manoharan, the Wagner Family Professor of Chemical Engineering and Professor of Physics at the Harvard John A....

Last week we shared the cool science on star and planet formation planned for Webb. Today, we get into details on how Webb will study planets around other stars, which are known as extrasolar planets, or exoplanets. Knicole Colón, Webb’s deputy project scientist for exoplanet science, takes us into the discovery space of exploring new worlds beyond our solar system. Dr. Colón brings a unique perspective as she is also the project scientist for the Transiting Exoplanet Survey Satellite (TESS), a mission that has found many exoplanet targets that Webb will observe....

This “clock” is made up of about 20,000 neurons in the hypothalamus. This area near the center of the brain coordinates your body’s unconscious functions, such as breathing and blood pressure. Humans aren’t the only lifeforms that have an internal clock system: All vertebrates – or mammals, birds, reptiles, amphibians, and fish – have biological clocks, as do plants, fungi, and bacteria. Biological clocks are why cats are most active at dawn and dusk, and why flowers bloom at certain times of the day....

Elevated blood pressure and hypertension, often referred to as ‘silent killer diseases’ in adults, are notorious for causing damage to the kidneys, heart, blood vessels, and brain, ultimately leading to death. The global cost of treating hypertension amounts to billions of dollars each year and is linked to an increasing number of health emergencies, including heart attacks and strokes. The European Society of Cardiology/European Society of Hypertension classifies blood pressure 130/85 mmHg as high-normal and 140/90 mmHg as hypertension....

After the successful splashdown, the capsule and crew were successfully recovered by SpaceX. The astronauts are on their way back to Houston, where they will be reunited with their families. “It really is a great day; I’m almost speechless as to how well things went today with the deorbit, entry, landing, and recovery of Bob and Doug,” said Steve Stich, manager of NASA’s Commercial Crew Program, during a post-splashdown briefing....

The international study has revealed between 2000 and 2013 the clearance of intact tropical forests resulted in a much higher level of carbon being emitted to the atmosphere than first believed – resulting in a 626 percent increase in the calculated impact on climate. UQ conservation scientist Dr. Sean Maxwell said this difference equated to two years of global land-use change emissions, and was previously unaccounted for due to a lack of full carbon accounting....

Astronomers used two telescopes atop Mauna Kea in Hawaii to find these supernovae, and they were able to spot them only because of the extreme luminosity of the supernovae. The blasts might have signaled the death of stars 100 times as massive as Sol. Although such superluminous explosions have been spotted relatively nearby universe, they ought to be more common in the early universe, when there were more supermassive stars....

The research, published in the leading journal Nature Communications on January 21, 2020, used isotopic analysis of minerals to calculate the precise age of the Yarrabubba crater for the first time, putting it at 2.229 billion years old — making it 200 million years older than the next oldest impact. Lead author Dr. Timmons Erickson, from Curtin’s School of Earth and Planetary Sciences and NASA’s Johnson Space Center, together with a team including Professor Chris Kirkland, Associate Professor Nicholas Timms, and Senior Research Fellow Dr....

An exhibit opening at the museum on Saturday, April 14, will showcase 23 pieces of California gold, including unusually large examples as well as smaller ones featuring extremely rare crystallographic forms. “This collection is incredible,” said Richard Kissel, the Peabody’s director of exhibitions and public programs. “The gold specimens on view are of superior quality — impressive physically and stunning aesthetically. The exhibit highlights the specimens’ beauty while offering insight into the history and science of gold mining....

Recent research indicates that bivalirudin is a safer and more effective anticoagulant than heparin for treating patients with the most severe kind of heart attack who undergo urgent percutaneous coronary intervention (PCI), with a 31% reduction in the risk of mortality or major bleeding. These are the results of a new study led by Mount Sinai’s Icahn School of Medicine researchers. This is the first large-scale clinical trial to examine the two anticoagulants most often used after PCI, and it demonstrates that bivalirudin given with a two- to four-hour high-dose infusion dramatically reduces thrombosis, major bleeding, and death when compared to heparin....

The findings were presented at the American Geophysical Union conference on December 3rd. People have suspected something odd in the region since the 1930s, because of the fragmented terrain. So far, only a handful of these buried craters have been discovered. Wei Xie, a graduate student in geophysics at the University of Alberta, and her colleagues peered underneath the Earth’s surface using data from boreholes drilled into the area and seismic wave surveys, which bounce off the boundaries between layers of different types of rock....

Dark energy, a mysterious substance thought to be speeding up the expansion of the Universe is really there, according to a team of astronomers at the University of Portsmouth and LMU University Munich. After a two-year study led by Tommaso Giannantonio and Robert Crittenden, the scientists conclude that the likelihood of its existence stands at 99.996 percent. Their findings are published in the journal Monthly Notices of the Royal Astronomical Society....
