An international team of scientists studying shorebirds, led by the University of Bath, has found that successful plover parents are more likely to divorce after nesting than those that did not successfully breed, in contrast to most other bird species which tend to split up after nest failure.
The researchers studied the mating behaviour of eight different species of Charadrius plovers, covering 14 populations in different locations across the world.
These shorebirds tend to lay 2-4 eggs per nest and can have up to four breeding attempts per season.
New research published in EPJ B reveals that the nature of the boundary at which an antiferromagnet transitions to a state of disorder slightly depends on the geometry of its lattice arrangement.
Calculations involving 'imaginary' magnetic fields show how the transitioning behaviours of antiferromagnets are subtly shaped by their lattice arrangements.
Antiferromagnets contain orderly lattices of atoms and molecules, whose magnetic moments are always pointed in exactly opposite directions to those of their neighbours.
New research published in EPJ D has revealed how robust initial states can be prepared in quantum information systems, minimising any unwanted transitions which lead to losses in quantum information.
Through new techniques for generating 'exceptional points' in quantum information systems, researchers have minimised the transitions through which they lose information to their surrounding environments.
A new study found the spread of ghost forests across a coastal region of North Carolina may have implications for global warming. Ghost forests are areas where rising seas have killed off freshwater-dependent trees, leaving dead or dying white snags standing in marsh.
After an infection of the human body with a pathogen, a cascade of reactions will usually be set into motion. Amongst others, specific cells of the immune system known as T cells get activated in the lymph node and will subsequently divide and proliferate.
At the same time, these cells will gain certain functions, that enable them to destroy other cells, that are e.g. infected by a virus. In addition, they produce certain proteins - so called cytokines - with which they can stop the reproduction of the pathogen.
PHILADELPHIA-- New findings suggest that late-onset Alzheimer's Disease is driven by epigenetic changes -- how and when certain genes are turned on and off -- in the brain. Results were published today in Nature Genetics.
"Zombie fires" and burning of fire-resistant vegetation are new features driving Arctic fires--with strong consequences for the global climate--warn international fire scientists in a commentary published in Nature Geoscience.
The 2020 Arctic wildfire season began two months early and was unprecedented in scope.
In a study published in Autophagy, researchers at the University of Maryland (UMD) shed new light on how Zika virus hijacks our own cellular machinery to break down a protein that is essential for neurological development and cellular communication, getting it to "eat itself". By triggering this process known as autophagy, Zika virus is able to degrade an important protein, a process that may contribute to the development of neurological or brain deficiencies and congenital birth defects in the newborns of infected pregnant women.
NASA analyzed the cloud top temperatures in Tropical Storm Kujira using infrared light to determine the strength of the storm. Infrared imagery revealed that the strongest storms were around Kujira's center and in a band of thunderstorms on the western side of the storm.
The low-pressure area designated System 97W consolidated and strengthened into a tropical depression on Sept. 26 by 5 p.m. EDT (2100 UTC). On Sept. 27 at 11 a.m. EDT (1500 UTC), the Joint Typhoon Warning Center noted that the depression had strengthened into a tropical storm and was renamed Kujira.
The era of the television brought with it the TV dinner -- a fast, convenient meal that, while nutritionally questionable, meant the whole family could gather together on the sofa to enjoy "The Ed Sullivan Show" and eat their Swanson Salisbury steak, too.
Over the next several decades, advancements in technology and the ubiquity of streaming services has allowed for the proliferation of binge-watching culture, where hours spent sedentary rack up faster than "Jeopardy" points, and greasy fast food is only a few taps on your smartphone away.
Nucleus leakage happened in some place, rendering this place a forbidden area for lives. This is a scene people frequently meet in science movies.
In these movies, traditionally the reactions to the leakage of the heroes are sending checking robots, examining by helicopter and even running through the block in flash under some circumstances. But there is a novel option now.
A new simulation approach has enabled a first practical, and highly accurate, computation of the noise characteristics of complex three-dimensional airfoil designs under extreme operating conditions. By shortening simulations that would have taken months or weeks to run to just days or hours, the new approach could accelerate the development of quieter airfoil designs to enable the next generation of aircraft and urban airborne vehicles.
Optimizing the integration of wind energy into a country's power network requires reliable forecasts of how wind speed and direction are likely to vary in time and space over the pending few hours. KAUST researchers have now developed a statistical model that provides the best forecasts yet for wind conditions across Saudi Arabia.
"Saudi Arabia is aiming to diversify its energy mix and has set targets to significantly increase the amount of renewable energy in the grid, starting with wind and solar," says former KAUST postdoc Amanda Lenzi.
Reading is the gateway for learning, but one-third of elementary school students in the United States do not read at grade level. Researchers at Carnegie Mellon University are exploring how the design of reading materials affects literacy development. They find that an overly busy page with extraneous images can draw the reader's attention away from the text, resulting in lower understanding of content.
The results of the study are available in the September issue of the journal npj Science of Learning.
New research by BAT indicates that modern oral products (MOPs) showed lower toxicity responses in certain assays than traditional cigarettes.
Scientists analysed the toxicological impact of one of BAT's nicotine pouch products, formerly called Lyft and now known as Velo, in an in vitro laboratory-based test. Velo was compared with a reference cigarette (1R6F) and reference Swedish-style snus pouch (CRP1.1).
