Livestock is a pivotal source of income for Latin American countries but the sector is one of the largest sources of greenhouse gas emissions (GHG) in the region. Agriculture in Latin America produces 20 percent of the region's emissions, 70 percent of which comes from livestock, according to research by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS).
The vapor that plants emit when they breathe serves to lower the land surface temperature, much like watering the yard on a hot day. Until now, the greenhouse effect has been blamed for the rise in global temperature. But an interesting study has shown that the Artic temperature rises when the moisture released by plants is reduced due to the increase of carbon dioxide (CO2 ) in the atmosphere.
A successful forage program is one in which mass production is consistently high for a long period, and management practices are essential to reach this goal. In the northern United States, researchers commonly study alfalfa. Producers from the southern region are interested in growing alfalfa, yet they need more information to adequately manage this forage crop in their environment.
Women who drink two or three cups of coffee a day have been found to have lower total body and abdominal fat than those who drink less, according to a new study published in The Journal of Nutrition.
Researchers examined data from the National Health and Nutrition Examination Survey, organised by the Center for Disease Control (CDC) in the United States and looked at the relationship between cups of coffee drunk per day, and both total body fat percentage and abdominal or 'trunk' fat (adiposity).
Researchers at University of Toronto Engineering and Carnegie Mellon University are using artificial intelligence (AI) to accelerate progress in transforming waste carbon into a commercially valuable product with record efficiency.
They leveraged AI to speed up the search for the key material in a new catalyst that converts carbon dioxide (CO2) into ethylene -- a chemical precursor to a wide range of products, from plastics to dish detergent.
Researchers from the Hubrecht Institute and Utrecht University generated an in-depth description of the human hormone-producing cells of the gut, in a large collaborative effort with other research teams. The results are presented in the scientific journal Cell on the 13th of May. These cells are hard to study, as they are very rare and unique to different species of animals. The researchers developed an extensive toolbox to study human hormone-producing cells in tiny versions of the gut grown in the lab, called organoids.
What The Viewpoint Says: Hardships faced by low-income children during the COVID-19 pandemic are discussed, and educational and policy reforms for the future are suggested in this article.

Insights into a flipping crystal could further research into the development of autonomous robots.
Hokkaido University scientists have fabricated a crystal that autonomously flips back and forth while changing its flipping patterns in response to lighting conditions. Their findings, published in a Chemistry Europe's journal, bring scientists closer to understanding how to build molecular robots that can prosecute complex tasks.
The problems of high temperature superconductor (HTSC) are important for the physics community and even the whole science area. Ever since its discovery, many researchers have conducted various studies, still lacking of widely accepted solutions. Recently, Prof. Jiangping Hu from Institute of Physics, Chinese of Science, proposed the "gene" theory of high temperature superconductivity based on the electronic properties of existing quasi-two dimensional HTSCs, and used it to search for new families of HTSCs.
Russian astrophysicists have come close to solving the mystery of where high-energy neutrinos come from in space. The team compared the data on the elusive particles gathered by the Antarctic neutrino observatory IceCube and on long electromagnetic waves measured by radio telescopes. Cosmic neutrinos turned out to be linked to flares at the centers of distant active galaxies, which are believed to host supermassive black holes.
As a new class of porous materials, noble metal aerogels (NMAs) have drawn tremendous attention because of their combined features including self-supported architectures, high surface areas, and numerous optically and catalytically active sites, enabling their impressive performance in diverse fields. However, current fabrication methods suffer from long fabrication periods, unavoidable impurities, and uncontrolled multiscale structures, discouraging their fundamental and application-orientated studies.
New research argues that legally protected large territories in Brazil are crucial to protect biodiversity and provide essential conditions for indigenous populations to maintain their traditional livelihoods.
Cappuccino, latte or short black, coffee is one of the most commonly consumed drinks in the world. But whether it's good or bad for your health can be clarified by genetics, as a world-first study from the University of South Australia's Australian Centre for Precision Health shows that excess coffee consumption can cause poor health.
Human self-control evolved in our early ancestors, becoming particularly evident around 500,000 years ago when they developed the skills to make sophisticated tools, a new study suggests.
While early hominins such as Homo erectus could craft basic handaxes as early as 1.8 million years ago, our hominin ancestors began to create more elaborate and carefully designed versions of these tools sometime before 500,000 years ago.
Patients suffering from chronic pancreatitis experience an either recurring or permanent inflammation of their pancreas. "In many cases, people develop this disease because they are drinking too much alcohol or they are smoking too much. Certain medication or high levels of lipids or calcium in a patient's blood can be another cause of pancreatitis," explained Heiko Witt, one of the two heads of the study and Professor for Pediatric Nutritional Medicine at the Else Kröner-Fresenius-Zentrum (EKFZ) at TUM.
