Working together with researchers from the University of Tübingen, the University of Tromsø, the UC Davis and the Sainsbury Laboratory in Norwich, biologists from Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) have discovered how tomato plants identify Cuscuta as a parasite. The plant has a protein in its cell walls that is identified as 'foreign' by a receptor in the tomato.
Researchers from University of Georgia, University of South Carolina, and University of Arkansas published a new paper in the Journal of Marketing that analyzes how asymmetries in pre-alliance network ties between a firm and its alliance partner affect the focal firm's financial performance and financial performance uncertainty.
The study, forthcoming in the Journal of Marketing, is titled "Effect of Alliance Network Asymmetry on Firm Performance and Risk" and is authored by Anindita Chakravarty, Chen Zhou, and Ashish Sharma.
Fossilized jaw bone fragments of a rat-like creature found at the Petrified Forest National Park in Arizona last year by a Virginia Tech College of Science Ph.D. candidate are in fact a newly discovered 220-million-year-old species of cynodont or stem-mammal, a precursor of modern-day mammals.
A world-first study on the Great Barrier Reef shows crown-of-thorns starfish have the ability to find their own way home--a behaviour previously undocumented--but only if their neighbourhood is stocked with their favourite food: corals.
Australian researchers observed the starfish emerging from their shelters in the afternoons so they could feed on coral during the night before returning home at dawn.
Gentoo penguins should be reclassified as four separate species, say scientists at the Milner Centre for Evolution at the University of Bath, after analysing the genetic and physical differences between populations around the southern hemisphere.
The researchers say that counting them as four separate species will aid in their conservation because it will make it easier to monitor any decline in numbers.
Investigations of deceased COVID-19 patients have shed light on possible lung damage caused by the virus.
The study, published today in The Lancet's eBioMedicine, by King's College London in collaboration with University of Trieste and the International Centre for Genetic Engineering and Biology in Italy, shows the unique characteristics to the SARS-CoV-2 virus and may explain why patients suffer from 'long COVID'.
Over the course of only a century, humanity has made an observable impact on the genetic diversity of the lion population. That's the conclusion of a recently published study by Drs. Caitlin Curry and James Derr from the Texas A&M University College of Veterinary Medicine & Biomedical Sciences.
The advent of genome science has given researchers an unprecedented ability to understand the root causes of a host of conditions. Justin Cotney, assistant professor of genetics and genome sciences in the UConn School of Medicine, has used this technology to identify a suite of genes and regulatory elements critical to normal heart development.
LOGAN, UTAH, USA -- Plastic has become ubiquitous in modern life and its accumulation as waste in the environment is sounding warning bells for the health of humans and wildlife. In a recent study, Utah State University scientist Janice Brahney cited alarming amounts of microplastics in the nation's national parks and wilderness areas.
LOS ANGELES (Nov. 2, 2020) -- New infection prevention practices implemented during the coronavirus pandemic have resulted in significantly shorter hospital stays for mothers and their babies, according to investigators at Cedars-Sinai, with no changes in the rates of cesarean deliveries, complications or poor outcomes.

Emergency Approvals for COVID-19: Evolving Impact on Obligations to Patients in Clinical Care and Research
In the United States, more than half of people living with a mental health disorder do not receive treatment, according to the National Institute of Mental Health, which is why primary-care clinics can play a leading role in depression care.
Research shows that collaborative care programs in which primary-care providers work with a depression care manager and a designated psychiatric consultant can more than double the likelihood of improving depression outcomes. But a new study published in Health Affairs shows that not all care is equal.
New research from the University of Sydney has found poisoning exposures in children and adolescents while at school are relatively common and appear to be increasing, highlighting the need for more robust prevention measures.
The authors state that by focusing on improved safety strategies, the incidence of poisonings in schools could decrease.
WASHINGTON, November 3, 2020 -- Certain molecules bind tightly to the surface of ice, creating a curved interface that can halt further ice growth. Some insects, plants, and sea-dwelling creatures contain protein molecules of this type that act as natural antifreeze agents, allowing the organisms to withstand freezing temperatures.
In The Journal of Chemical Physics, by AIP Publishing, scientists report a computational method to model ice binding using a biasing technique to drive the formation of ice in the simulation.
Over 70 percent of U.S. adults have overweight or obesity. While primary care physicians (PCPs) are often the most immediate source of counseling for those trying to lose weight, most PCPs do not have the time, training, or support to guide their patients through a comprehensive weight loss program. Additionally, studies of online weight loss programs have found mixed levels of success.
