River deltas and their adjoining wetlands are being threatened by rising sea levels and decreased river sediment loads. Better understanding how coastlines along river deltas are created and sustained will be critical to preserving and even restoring them in the future.
High usage and unreasonable methods have caused excessive residues of glyphosate in agricultural products, so it's necessary to find rapid and highly selective methods for detecting glyphosate residues. Laboratory instrument–based methods or enzyme-inhibition methods usually have harsh environmental requirements and complex operational problems. Therefore, the establishment of a highly selective...
La Trobe University research reveals an inexpensive "peer support" model used extensively by frontline health workers may be the solution to teacher burnout, which has left schools across the country unable to operate effectively.
A new thesis shows that wooden pile foundations show visible damage after only a year if the groundwater level lowers. This can cause settlements of buildings in a matter of a few years.
A new genetic discovery adds weight to a theory that motor neuron degenerative diseases are caused by abnormal lipid (fat) processing pathways inside brain cells. This theory will help pave the way to new diagnostic approaches and treatments for this group of conditions. The discovery will provide answers for certain families who have previously had no diagnosis.
Species have intrinsic value, but also provide ecosystem services of major economic value, for example, bees that pollinate our crops. However, as such values are hard to translate into figures, currently, they remain easy to dismiss altogether. In a new study, a research team conceptualizes a species stock market for unified valuation of all species. By using digitized information from museums,...
A team has been studying the current state of research on the plant colonization of land that occurred some 500 million years ago.
A single MRI scan of the brain could be enough to diagnose Alzheimer's disease, according to new research.
Planting forests is one way to mitigate climate change. The origin of seeds is crucial to optimize the success of planted trees and their ability to adapt to future climates. INRAE and ONF (French National Forest Office) ran a large-scale study for more than 30 years using a collection of about 100 populations of sessile oak from all over Europe. Spread over four experimental sites in France, they...
Acute lymphoblastic leukemia (ALL) is the most common cancer affecting children. The T-ALL form of leukemia that emerges from early T lineage cells has a poorer prognosis than B-lineage ALL. The prognosis for relapsed T-ALL is very poor and new therapies are sorely needed. Medical researchers have discovered a new combination of drugs that is effective against T-ALL.
America's national parks are in crisis, and the environmental disaster unfolding at Yellowstone National Park is the latest example of extreme weather driven by climate change battering parkland.
A research team led by Ji Shulin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CAS) studying the mechanism of silver nanowire films has recently discovered that the better the plasticity of the films, the more resistant they were to shear fracture. Results were published in Nanotechnology.
A growing concern for climate change and sustainable use of natural resources has led to the adoption of alternative forms of energy. Nuclear power is considered a panacea for the environmental degradation caused by fossil fuels. However, its environmental impact and natural resource use need to be assessed. Now, researchers have addressed this issue, revealing interesting findings in their...
Thanks to the war in Ukraine, there is a shortage of agricultural chemicals. As each adult produces enough pee annually to fertilise 145kg of wheat, perhaps bodily waste is the answerName: Peecycling.Age: As a term, dates to about 2006; as a practice, centuries old. Continue...
British Columbia has become the first province to be granted an exemption under the Controlled Drugs and Substances Act to remove criminal penalties for possession of opioids, cocaine, methamphetamine and MDMA for personal use.
The use of antibiotics helps fight bacterial infection, but the abuse of antibiotics has resulted in the emergence and widespread prevalence of "super bacteria," making the treatment of infectious diseases a worldwide problem again.
Piezoelectric materials are applicable in the biomedical field, and if they can be biocompatible and degradable, it will be a big step towards real applications. Recently, a research team at City University of Hong Kong (CityU) developed a simple exfoliation method to prepare ultrathin films of small intestine tissues from sheep. This biological tissue has been considered to have no piezoelectric...
The bacteria in the gut are crucial for our health. They contribute to the development of an effective immune system and ward off pathogens. However, when harmful gut bacteria multiply or beneficial ones are lost, one develops health problems. But even in healthy people, the intestinal flora changes with old age. Anti-inflammatory bacteria become rarer, and species linked to inflammatory processes...
Forests throughout the world are shrinking year after year—and Brazil is the epicenter. According to the World Wildlife Fund, more than a quarter of the Amazon rainforest will be devoid of trees by 2030 if cutting continues at the same speed.
The structure of the universe is often described as being a cosmic web of filaments, nodes, and voids, with the nodes being clusters of galaxies, the largest gravitationally bound objects known. These nodes are thought to have been seeded by small-amplitude density fluctuations like those observed in the cosmic microwave background (CMB) which grew until they collapsed into the structures seen...
Optics researchers at The University of Texas at Dallas have shown for the first time that a new method for manufacturing ultrathin semiconductors yields material in which excitons survive up to 100 times longer than in materials created with previous methods.
A subunit of voltage-gated calcium channels was found to have a functional role in T-cells, according to a Northwestern Medicine study published in Nature Communications.
A new publication from Opto-Electronic Advances discusses how deep learning makes single-shot, high-resolution structured light 3D imaging possible.
For the last two-plus years, people hoping to meet their soulmate in person have had a rough time. Lockdowns and uncertainty about social gatherings have led many people to turn to dating apps. People who feel they have lost months or years of their dating life may be eager to avoid the perils of dating apps—ghosting, backburner relationships, or just wasting time chatting with the wrong people.
