A team reports that carefully constructed stacks of graphene -- a 2D form of carbon -- can exhibit highly correlated electron properties. The team also found evidence that this type of collective behavior likely relates to the emergence of exotic magnetic states.
Researchers may have discovered a safe new way to manage blood sugar non-invasively. Exposing diabetic mice to a combination of static electric and magnetic fields for a few hours per day normalizes blood sugar and insulin resistance. The unexpected and surprising discovery raises the possibility of using electromagnetic fields (EMFs) as a remote control to manage type 2 diabetes.
New analysis of the DNA sequence of the male-specific Y chromosomes from all living species of the great ape family helps to clarify our understanding of how this enigmatic chromosome evolved.
The presence of diamonds in an outcrop atop an unrealized gold deposit in Canada's Far North mirrors the association found above the world's richest gold mine, according to University of Alberta research that fills in blanks about the thermal conditions of Earth's crust three billion years ago.
Patients who experienced encephalophathy tended to be male, older (65, on average), and enter the hospital soon after COVID-19 symptoms set...
"If you have to sneeze, you're in trouble," Bill Johnson said of wearing the Air, an acrylic visor that evokes 1960s Soviet cosmonaut culture. Johnson, 44, a voice and video engineer in Utah, had tested an early model of the device on an airplane from Salt Lake City to Seattle to Ketchikan, Alaska, then on a three-hour ferry ride and a floatplane to reach his bush cabin."I flew...
An online movement to save sharks from becoming the next victims of the COVID-19 pandemic is growing in support.
Nobel physics laureate Roger Penrose on Tuesday said his late colleague Stephen Hawking richly deserved a share of the prize after the British scientists conducted pioneering research into black holes.
Rome wasn't built in a day, but some of Earth's finest gemstones were, according to new research from Rice University.
The loss of flowering plants and the widespread use of pesticides could be a double punch to wild bee populations. In a new study, researchers at the University of California, Davis, found that the combined threats reduced blue orchard bee reproduction by 57 percent and resulted in fewer female offspring. The study was published in the journal Proceedings of the Royal Society B.
Scientists have long known that the plant hormone auxin controls many aspects of plant growth, development, and responses to the environment. Only more recently have they begun to understand that there is also a link between auxin and leaf spotting diseases.
An activist speaking out about inadequate waste and water sanitation in rural America, an author of young adult and children's literature reflecting the world's diversity, and a neuroscientist who used mathematics to study the brain's development are among the 21 recipients of this year's "genius grants".
With a deafening roar, the swollen Sesia river swept down the Alpine valley in northern Italy to engulf the plains below, drowning the country's so-called "golden triangle" of rice paddies in mud.
For US astronomer Andrea Ghez, who won this year's Nobel Physics Prize, what makes black holes so fascinating is how tricky they are to conceptualize.
Pollution off the Pacific shoreline of the remote Kamchatka peninsula has caused the mass death of marine creatures, Russian scientists said Tuesday.
The European Union's Earth observation program said Tuesday that the ozone hole over Antarctica has swelled to its largest size and deepest level in years.
Water-based threats like storm surge and flooding are responsible for 90% of the deaths in powerful storms — but common scales don't reflect...
Dexamethasone can cause euphoria and reduce fever, but it also weakens the immune system and leaves the patient to fight off the...
South Asia accounted for nearly two-fifths of the world's poor, nearly half of the world's malnourished children and was home to the largest number of stunted children in 2015. Despite this, the region had made significant progress in lifting people out of poverty—and between 1990 and 2015 its poverty rate sharply declined from 52% to 17%.
The world is underestimating the economic effects of climate change by trillions of dollars, according to a new study co-authored by scientists from the University of Warwick.
Though some believe prehistoric humans lived in harmony with nature, a new analysis of fossils shows human arrival in the Bahamas caused some birds to be lost from the islands and other species to be completely wiped out.
The study of past climates—palaeoclimatology—involves the interrogation of physical, chemical and biological information stored in natural archives, such as ice cores and ocean sediments.
Researchers led by prof. Wout Boerjan (VIB-UGent Center for Plant Systems Biology) have discovered a way to stably finetune the amount of lignin in poplar by applying CRISPR/Cas9 technology. Lignin is one of the main structural substances in plants and it makes processing wood into, for example, paper difficult. This study is an important breakthrough in the development of wood resources for the...
Proteins transduce information and signals within the human body by changes in their structures. For example, hormones binding to their target proteins cause a structural change which in turn opens new binding sites for other proteins elsewhere on the surface of the protein. Researchers refer to this coupling of different, distant binding sites as allostery. An interruption of this coupling leads...
