China will stop funding coal projects overseas, President Xi Jinping announced Tuesday, all but ending the flow of public aid for the dirty energy contributing to the climate crisis.
Vancouver's Stanley Park has fully reopened to the public after a two-week nighttime closure to cull aggressive...
Plastic pollution clogs river systems for considerably longer than previously thought, new research shows.
Researchers have found that older adults may benefit from a specific diet called the MIND diet even when they develop these protein deposits, known as amyloid plaques and tangles.
Scientists have developed a method using machine learning to better analyze data from a powerful scientific tool: nuclear magnetic resonance (NMR). One way NMR data can be used is to understand proteins and chemical reactions in the human body. NMR is closely related to magnetic resonance imaging (MRI) for medical diagnosis.
Researchers seek to point a way toward a unified theory for how DNA changes shape when expressing genes. The scientists use an approach called statistical mechanics to explore the phenomenon of so-called expression waves of gene regulation. The group hopes to reconcile a long-standing gulf between the two scientific fields most involved in the topic, using concepts common to biology and physics.
Our subjective experience appears to us in a continuous stream of integrated information, and researchers now explore the question: Which characteristics should brain activity have to support this type of conscious experiences? The group searched for integrated structures that encompass most of the brain but change configuration from time to time. Their hypothesis was these structures should...
Carbon fiber reinforced polymer composite structures are important in several industries, yet the electrical behavior of a composite is challenging to measure or predict because of the electrical conductivity of constituent carbon fibers and the composite's complex hierarchical microstructure. Researchers report a direct measurement of the transverse electrical resistivity of a single carbon...
Researchers construct an embryo-like structure from human stem cells, resulting in a new way to study the earliest stages of development.
Researchers used exosomes, tiny nanoparticles capable of being taken up by cells, to deliver novel protein into the cells of mice infected with HIV. The protein attached to HIVs' genetic material and prevented it from replicating, resulting in reduced levels of HIV in the bone marrow, spleen, and brain. The study paves the way for the development of novel delivery systems for suppressing HIV.
A recurrent neural network structure exists in the most important part of the brain -- the frontal cortex -- and this network is less complex than has been thought and mostly unidirectional, new research shows.
A team of paleontologists excavated four dinosaurs in northeastern Montana this summer. The four dinosaur fossils are: the ilium -- or hip bones -- of an ostrich-sized theropod, the group of meat-eating, two-legged dinosaurs that includes Tyrannosaurus rex and raptors; the hips and legs of a duck-billed dinosaur; a pelvis, toe claw and limbs from another theropod that could be a rare ostrich-mimic...
An intrinsic magnetic topological insulator MnBi2Te4 has been discovered with a large band gap, making it a promising material platform for fabricating ultra-low-energy electronics and observing exotic quantum phenomena.
New research is providing a better understanding of what influences fussy eaters, and what is more likely to increase or decrease picky eating in children under 10.
Researchers have shown that two lab-developed and nasally-delivered peptides helped slow the spread of alpha-synuclein in mice. 'If these results can be replicated in patients, it would be a remarkable advance in the treatment of devastating neurological disorders,' says the lead author.
A new study from Ph.D. graduate Jacob Ward, Professor Jeremy Michalek of Engineering and Public Policy (EPP) and Mechanical Engineering (MechE), and Associate Professor Costa Samaras of Civil and Environmental Engineering at Carnegie Mellon University quantifies the costs and benefits of taking a trip with a transportation network company (TNC), like Uber or Lyft. They found that a TNC trip...
The ancient massive trees of Sequoia National Park's famed Giant Forest were unscathed Tuesday even though a wildfire has been burning near them on the western side of California's Sierra Nevada for nearly two weeks.
Lowering gillnets into the water—instead of using them on the surface—can lower the chances of tuna fishermen accidentally hauling in dolphins and whales, according to new research led by Florida International University and World Wildlife Fund (WWF) in Pakistan.
When the novel coronavirus led to a global pandemic last year, doctors and researchers rushed to learn as much as possible about the virus and how our bodies respond to it.
While humans are able to survive in arid climates, great apes need swaths of lush forest in Africa (bonobos, chimpanzees, gorillas) or Southeast Asia (orangutans) to thrive, except for some innovative savanna chimpanzees.
The night sky is going to get much busier thanks to thousands of new internet satellites set to launch over the next few years—and researchers say it's going to affect Canada more than most places on Earth.
Researchers at the FAMU-FSU College of Engineering and the National High Magnetic Field Laboratory have new insight about the formation of vortices in a type of quantum fluid, work that could help our comprehension of the physics mystery of how vortex clusters form and provide valuable understanding into the atmospheric swirling motion on planets such as Earth and Jupiter.

Millions of people depend on oceans for food and income. A recent report from the Intergovernmental Panel on Climate Change states that at least 83 percent of the ocean's surface will continue to warm this century, which will negatively affect lives and livelihoods. Additionally, a new international study that includes research from LSU found that higher resolution data are critical to predict how...
Mars is the solar system’s near-miss world. Earth may have gotten everything right when it came to sustaining life—atmosphere, water, proximity to the sun. Mercury, Venus and the outer planets, with their extreme temperatures and inhospitable chemistry, may have gotten everything wrong. Mars, on the other hand, came so close, yet fell short. Thanks to data from rovers and other...
Spending time in nature can have mental, physical and social benefits for children. While schools offer a chance for students of all backgrounds to get outside in nature, researchers from North Carolina State University found natural spaces like woods or gardens were relatively rare in a small sample of elementary and middle schools in Wake County.
Reactive nitrogen emissions contribute to greenhouse gases, as well as air and water pollution. For the first time, researchers from McGill University have calculated Canada's nitrogen footprint (akin to a carbon footprint) at both national and provincial levels. They looked at the three primary sectors that contribute nitrogen to the environment to calculate the annual average nitrogen footprint:...
U.S. workplaces are becoming increasingly diverse, a result of both a younger and more racially diverse working class and successful diversity hiring efforts. In federal agencies alone, minority employees jumped from 28.4% of the workforce in 1994 to 36.7% in 2017.
Researchers at Lawrence Livermore National Laboratory have calculated moment tensors for 130 underground nuclear and 10 chemical test explosions that have taken place at the Nevada National Security test site.
Early Maya cities featured monumental complexes, which centered on a shared form of religion but these complexes transformed radically once kingship emerged in 400 B.C. To solidify their power, rulers throughout the Maya lowlands would change these complexes, installing their mark on the landscape and reshaping how people remember it, according to a Dartmouth study published in Ancient...
