President Donald Trump's controversial use of social media is widely known and theories abound about its ulterior motives. New research published today in Nature Communications claims to provide the first evidence-based analysis demonstrating the US President's Twitter account has been routinely deployed to divert attention away from a topic potentially harmful to his reputation, in turn suppressing negative related media coverage.
Groups of animals consider multiple factors before deciding whether to fight rivals, researchers say.
Before one-on-one fights, animals are known to make decisions based on factors including the size and strength of the opponent, the outcome of recent fights and the importance of the prize.
But scientists from the universities of Exeter and Plymouth say previous research has often overlooked complexity in group conflicts and assumed that larger groups will always win.
When wolves returned to Yellowstone in 1995, no one imagined the predators would literally change the course of rivers in the national park through cascading effects on other animals and plants. Now, a Stanford University-developed approach holds the promise of forecasting such ecosystem changes as certain species become more prevalent or vanish altogether.
PHILADELPHIA - Developments in cancer treatment and care have dramatically improved survival for cancer patients, however, these treatments can also damage other parts of the body, including the heart. At the American Heart Association's Scientific Sessions 2020, physician-researchers from the Perelman School of Medicine at the University of Pennsylvania will present findings about cardiac care for cancer patients and survivors.

A new UC Riverside study shows flame retardants found in nearly every American home cause mice to give birth to offspring that become diabetic.
These flame retardants, called PBDEs, have been associated with diabetes in adult humans. This study demonstrates that PBDEs cause diabetes in mice only exposed to the chemical through their mothers.
Animals that live slowly - breeding less rapidly and living longer - could be "reservoirs" of diseases that could jump to new species including humans, new research suggests.
Some species "live fast and die young", devoting effort to reproduction, while others conserve more energy for survival.
The Covid-19 pandemic has drawn attention to fast-spreading infectious diseases, but the new study - by the University of Exeter - focusses on "endemic" diseases that co-exist with host species for long periods of time.
Bristol researchers have developed a tiny device that paves the way for higher performance quantum computers and quantum communications, making them significantly faster than the current state-of-the-art.
At this year's American College of Rheumatology virtual meeting, Hospital for Special Surgery (HSS) presented exciting research related to rheumatology and orthopedic surgery.
The research focuses on the diagnosis of renal disorders, the risk of venous thromboembolism after total knee replacement (TKR), and the care of pediatric and young adult patients with rheumatologic diseases. There are also studies related to the care of rheumatology patients during the COVID-19 pandemic.
Ultraviolet nanoimprint lithography (UV-NIL) is a manufacturing technique for producing nanostructures using UV-curable resin. One of its main advantages is its sheer simplicity; UV-NIL essentially consists of pouring a liquid resin over a nanostructured mold, making the resin solidify using UV irradiation, and then releasing it from the mold. The result is a solid polymer with a nanostructure that is the inverse of that of the mold.
During the last Ice Age about 20,000 years ago, iron-containing dust acted as a fertilizer for marine phytoplankton in the South Pacific, promoting CO2 sequestration and thus the glacial cooling of the Earth. But where did the dust come from? Researchers led by Dr. Torben Struve, geoscientist at the University of Oldenburg, Germany, have investigated this open question of climate history, which is also relevant with respect to current climate change.
A team of researchers from Kaunas University of Technology and Lithuanian University of Health Sciences proposed a non-invasive method for detection of melanoma. A patented computer-aided diagnostic system developed by Lithuanian scientists proved to be more than 90% accurate in detecting malignancy in diagnostic images of skin lesions acquired from 100 patients.
When natural motion comes to mind, plants are most likely at the bottom of most people's list. The truth is that plants can perform complex movements, but they only do so very slowly. The main mechanism behind plant movement is water absorption and release; the cellulose present in plant tissues draws water in and expands, and the underlying arrangement of cellulose fibers guides the motions as needed. Now, what if we drew ideas from this natural phenomenon and used them for future engineering applications?
The use of digital videos in learning processes is becoming increasingly widespread, particularly within the educational context created by the COVID-19 pandemic. In a situation where moving education online is the only recourse, carrying out research into the impacts of using this kind of audiovisual material becomes imperative.
The UK's supply of fruit and vegetables has become increasingly reliant on imports from countries vulnerable to climate change, according to a new study in Nature Food.
Solar radiation, rain, humidity and extreme temperatures. Cultural heritage is exposed to an array of external factors that deteriorate it over time. Among them, the most aggressive may well be microbial contamination, caused by an ample ecosystem of fungi, algae, bacteria and microscopic lichens that grow inside the pores of the materials the buildings are made of and they make these buildings less resistant to other external agents, speeding up the deterioration process over time.
