Argonne researchers quantify how to reduce emissions by farms changing their practices and adopting novel technologies.

The seventh tropical depression of the Eastern Pacific Ocean has formed. NASA's Terra satellite used infrared light to identify the area of strongest storms and coldest cloud top temperatures in Tropical Depression 7E.
In their zeal to promote the importance of climate change as an ecological driver, climate scientists increasingly are ignoring the profound role that indigenous peoples played in fire and vegetation dynamics, not only in the eastern United States but worldwide, according to a Penn State researcher.
Over 360 scientists from 42 countries—led by the University of Göttingen and Westlake University China—call for transition of food production systems to agroecological principles.
A new relationship between humanity and the ocean is required to secure the continuity of the diverse life support roles provided by the sea, according to a paper published in Nature Communications on 17 July 2020.
Nicknamed the "billion-dollar beetle" for its enormous economic costs to growers in the United States each year, the western corn rootworm is one of the most devastating pests farmers face.
For the first time, scientists at the Morgridge Institute for Research have generated near atomic resolution images of a major viral protein complex responsible for replicating the RNA genome of a member of the positive-strand RNA viruses, the large class of viruses that includes coronaviruses and many other pathogens.
The homes of wealthy Americans generate about 25% more greenhouse gases than residences in lower-income neighborhoods, mainly due to their larger size. In the nation's most affluent suburbs, those emissions can be as much as 15 times higher than in nearby lower-income neighborhoods.
Research by the University of Liverpool has revealed that strange behaviour of the magnetic field in the South Atlantic region existed as far back as eight to 11 million years ago, suggesting that today's South Atlantic Anomaly is a recurring feature and unlikely to represent an impending reversal of the Earth's magnetic field.
Cellular signal transmission is not only optimized for precision—it also includes a cost cap. The relationship between information and energy, a concept well established in physics and engineering, is likely to fundamentally shape cellular signaling networks. One of the questions addressed by researchers at the Max Planck Institute for Terrestrial Microbiology, headed by biophysicist Victor...
Many exoplanets known today are 'super-Earths,' with a radius 1.3 times that of Earth, and 'mini-Neptunes,' with 2.4 Earth radii. Mini-Neptunes, which are less dense, were long thought to be gas planets, made up of hydrogen and helium. Now, scientists at the Laboratoire d'Astrophysique de Marseille (CNRS/Aix-Marseille Université/Cnes) have examined a new possibility, namely that the low density...
If civilization ever succumbs to global warming, nuclear annihilation, an unrelenting pandemic or a martian invasion, some future civilization—or alien life form—might well still be able to reconstruct today's computers and compose advanced machine learning algorithms … and perhaps even play a round of Doom while they're at it.
Climate change is starving polar bears into extinction, according to research published Monday that predicts the apex carnivores could all but disappear within the span of a human lifetime.
It was against the backdrop of a pounding surf one recent morning that almost 30 people had gathered on the cragged and slippery folds of White Point tidal pools in San Pedro and set to work with gardening spades, buckets and bags.
Tales of the ocean swallowing places are as ancient as the myth of Atlantis, but there is an element of truth in the science, according to a NOAA-backed expedition set for Florida's Gulf Coast.
A study published today found national governments repeatedly resisted the placement of 41 UNESCO World Heritage sites—including the Great Barrier Reef—on the World Heritage in Danger list. This resistance is despite the sites being just as threatened, or more threatened, than those already on the in Danger list.
Scientists have long debated the idea that global climate changes have forced river erosion rates to increase over the past five million years. New field data gleaned from a multi-institution, collaborative study of North America's rugged Yukon River basin, near storied Klondike goldfields, reveal profound increases in river erosion during abrupt global intensification of climate fluctuations...
A research team, led by Dr. Hyung-Suk Oh and Dr. Woong Hee Lee of the Clean Energy Research Center of the Korea Institute of Science and Technology (KIST), working in cooperation with the Technische Universität Berlin (TUB), announced that they had developed a nano-sized, coral-shaped silver catalyst electrode and large-area, high-efficiency carbon dioxide conversion system, which can be used to...
Kansas State University physicists have taken extremely fast snapshots of light-induced molecular ring-opening reactions—similar to those that help a human body produce vitamin D from sunlight. The research is published in Nature Chemistry.
Things can always be done faster, but can anything beat light? Computing with light instead of electricity is seen as a breakthrough to boost computer speeds. Transistors, the building blocks of data circuits, are required to switch electrical signals into light in order to transmit the information via a fiber-optic cable. Optical computing could potentially save the time and energy used for such...
Using specialized nanoparticles, MIT engineers have developed a way to monitor pneumonia or other lung diseases by analyzing the breath exhaled by the patient.
Engineers have taken their inspiration from shells and grapefruits to create what they say is the first manufactured non-cuttable material.
Homo Neanderthaliensis did not become extinct because of changes in climate. At least, this did not happen to the several Neanderthal groups that lived in the western Mediterranean 42,000 years ago. A research group of the University of Bologna came to this conclusion after a detailed paleoclimatic reconstruction of the last ice age through the analysis of stalagmites sampled from some caves in...
In a new laboratory study, experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) investigated how many microplastic particles would be absorbed in the muscle tissue of young European sea bass after being given feed with extremely high microplastic particle content for a period of four months. At least with regard to this particular food fish, their...
Cheese production relies on coagulation of milk proteins into a gel matrix after addition of rennet. Milk that does not coagulate (NC) under optimal conditions affects the manufacturing process, requiring a longer processing time and lowering the cheese yield, which, in turn, has economic impact. In an article appearing in the Journal of Dairy Science, scientists from Lund University studied the...
