Physicists have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results represent the largest number of particles that have ever been mutually entangled experimentally.
A new study provides the first observational evidence that a supermassive black hole at the center of a large galaxy can power huge, wide-angled outpourings of material from deep inside the galaxy's core. These outflows remove massive quantities of star-making gas, thus influencing the size, shape and overall fate of the host galaxy.
Increasing rainfall in certain parts of the tropics, colloquially described as the wet get wetter and warm get wetter, has long been a projection of climate change. Now observations have shown that an increase in large thunderstorms is the primary reason for this phenomenon.
Ecopassages may be less effective reptile road mortality mitigation tools when fences fail to keep reptiles from accessing the road.
Researchers have developed a county-by-county map of the United States' "lower 48" that tells a story of land cover and development across the nation, and could provide a framework for planners and policy makers as they consider future development.
When it comes to romantic relationships, a research review article suggests humans are wired to break-up and move on. Drawing largely upon the field of evolutionary psychology, they say men and women might break up for different reasons. For instance, a man is more likely to end a relationship because a woman has had a sexual relationship with another man. On the other hand, a woman may be more likely to break up if her partner has been emotionally unfaithful.
Two of the most destructive termite species in the world are swarming together in South Florida. They might mate, forming a hybrid, and that worries the UF/IFAS scientists who found the superswarm.
Scientists have created a new chemical process that makes use of the widely available rare-earth metal cerium to improve the manufacture of nylon.
Two practicing emergency medicine physicians -- both thought leaders at the forefront of finding solutions to the public health crisis of gun violence -- urge their colleagues to take direct action to protect the health and safety of patients and communities.
Water exists in myriad forms, and for poets and scientists alike this structurally simple yet at the same time behaviourally complex molecule never fails to fascinate. In our everyday lives we are familiar with water in its more common liquid, ice and vapour forms. Scientists also study water under more extreme conditions, including at high pressures, where it can exist in the solid state even at room temperature.
A new book summarizes research on the interplay of sleep and various components of emotion and affect that are related to mood disorders, anxiety disorders, bipolar disorder and depression.
Research on lemurs' geographic mobility may help direct future conservation efforts on Madagascar. For centuries, scientists have marveled at Madagascar's lemur species, whose origins are unique to Madagascar. Unfortunately, all large-bodied species of lemur (as well as other native fauna larger in size than a small dog) have gone extinct in the past 2,000 years, most likely due to hunting pressure and deforestation. Researchers believe that gaining a better understanding of how animal mobility has been affected by the loss of species and habitat will be beneficial to current and future conservation efforts on the island.
A ubiquitous type of phytoplankton -- tiny organisms that are the base of the marine food web -- appears to be suffering from the effects of ocean acidification caused by climate change. According to authors of a new study, the single-celled organism under study is a type of "calcifying" plankton called a coccolithophore, which makes energy from sunlight and builds microscopic calcium carbonate shells, or plates, to produce a chalky suit of armor.
A two-year study evaluated an organic fish fertilizer in a squash/collard rotation, and compared its effectiveness to inorganic sources. Although yields were reduced in the crops grown with hydrolyzed fish fertilizer treatments, economic analyses showed that premium prices and potential profits associated with organic products were enough to offset reduced yield. The authors said that the use of hydrolyzed fish fertilizer could be an economically feasible option in organic vegetable production.
A strong association between the lifestyles of indigenous communities and their gut microbial ecologies (gut microbiome) has been discovered by researchers. This study that may have implications for the health of all people, they say.
New research exposes the weakness of password strength meters, and shows consumers should remain skeptical when the bar turns green in order to create strong passwords.
Two professional societies of human geneticists have issued a position statement on the promise and challenges of non-invasive prenatal testing, a procedure to test blood drawn from pregnant mothers for Down syndrome and other chromosomal disorders in the fetus. The document addresses the current scope of and future improvements in NIPT technology, ways it may fit with existing prenatal screening protocols, options and priorities in implementation, and associated social and ethical issues.
Carbon nanotube fibers may provide the best way to communicate directly with the brain. The research could enable new strategies for treating neurological disorders like Parkinson's, investigators say.
An advanced form of life support that takes over for the failing hearts and lungs of critically ill patients saves lives. But for adults, the odds of surviving depend on which hospital provides the life-supporting treatment -- with the best odds at ones that use the technique dozens of times a year, a new study finds.
A variety of dialectical behavior therapy interventions helped to reduce suicide attempts and nonsuicidal self-injury acts in a randomized clinical trial of women with borderline personality disorder who were highly suicidal.
