The burning of sugarcane, carried out to eliminate dry leaves before harvesting, for years altered the air quality in the central region of the State of São Paulo, Brazil. The particles launched into the atmosphere during the process were visible to the region's inhabitants and were deposited in the streets and on cars.
Atmospheric pollution also caused respiratory problems among the population, impacts on biodiversity and the native vegetation, and contaminated rivers.
DALLAS (SMU) - Geophysicists at SMU say that evidence of leak occurring in a West Texas wastewater disposal well between 2007 and 2011 should raise concerns about the current potential for contaminated groundwater and damage to surrounding infrastructure.
HOUSTON - (Nov. 25, 2019) - Rice University researchers have developed an inorganic method to synthesize ammonia that is both environmentally friendly and can produce the valuable chemical on demand under ambient conditions.
The Brown School of Engineering lab of materials scientist Jun Lou manipulated a two-dimensional crystal it understands well -- molybdenum disulfide -- and turned it into a catalyst by removing atoms of sulfur from the latticelike structure and replacing the exposed molybdenum with cobalt.
Montreal, November 25, 2019 - A research team led by Dr. Claudia Kleinman, an investigator at the Lady Davis Institute at the Jewish General Hospital, together with Dr. Nada Jabado, of the Research Institute of the McGill University Health Centre (RI-MUHC), and Dr. Michael Taylor, of The Hospital for Sick Children (SickKids), discovered that several types of highly aggressive and, ultimately, fatal pediatric brain tumors originate during brain development. The genetic event that triggers the disease happens in the very earliest phases of cellular development, most likely prenatal.

The search for youthfulness typically turns to lotions, supplements, serums and diets, but there may soon be a new option joining the fray. Rapamycin, a FDA-approved drug normally used to prevent organ rejection after transplant surgery, may also slow aging in human skin, according to a study from Drexel University College of Medicine researchers published in Geroscience.
NASA's Aqua satellite passed over eastern North Atlantic Ocean and captured an infrared view of what is now Extra-tropical cyclone Sebastien. Sebastien transitioned from a tropical storm to an extra-tropical storm on Nov. 24. It has coupled with a cold front and is now headed for the United Kingdom.
Sebastien's Final Advisory
LOS ALAMOS, N.M., November 25, 2019--Extreme drought's impact on plants will become more dominant under future climate change, as noted in a paper out today in the journal Nature Climate Change. Analysis shows that not only will droughts become more frequent under future climates, but more of those events will be extreme, adding to the reduction of plant production essential to human and animal populations.
A transition from wild collection of herbs to forest farming needs to occur in Appalachia to make the opaque, unstable and unjust supply chain for forest medicinal plants such as ginseng sustainable, according to a team of researchers who have studied the market for more than a decade.
Concussion, the most common form of traumatic brain injury, has been linked to an increased risk of depression and suicide in adults. Now new research published by The University of Texas Health Science Center at Houston (UTHealth) suggests high school students with a history of sports-related concussions might be at an increased risk for suicide completion.
A study involving scientists at the University of Arizona and the University of Queensland provides new insight into how the small brains of mantis shrimp - fierce predators with keen vision that are among the fastest strikers in the animal kingdom - are able to make sense of a breathtaking amount of visual input.
The researchers examined the neuronal organization of mantis shrimp, which are among the top predatory animals of coral reefs and other shallow warm water environments.
Future aerial design may owe a nod of thanks to five parrotlets flapping around in an instrumented flight chamber at Stanford University. They revealed that counter to conventional understanding of how animals and planes fly, the birds can utilize drag to support their body weight during takeoff and employ lift as a brake in their landings.
An international team of scientists, led by the University of Manchester, has developed a metal-organic framework, or MOF, material that provides a selective, fully reversible and repeatable capability to capture a toxic air pollutant, nitrogen dioxide, produced by combusting diesel and other fossil fuels.
SEATTLE, November 23, 2019 -- Trapped water in the ear canal can cause infection and even damage, but it turns out that one of the most common methods people use to get rid of water in their ears can also cause complications. Researchers at Cornell University and Virginia Tech show shaking the head to free trapped water can cause brain damage in small children.
CLEVELAND--Scientists from the Case Western Reserve University digital imaging lab, already pioneering the use of Artificial Intelligence (AI) to predict whether chemotherapy will be successful, can now determine which lung-cancer patients will benefit from expensive immunotherapy.
