Young adults who increased their use of social media were significantly more likely to develop depression within six months, according to a new national study authored by Dr. Brian Primack, dean of the College of Education and Health Professions and professor of public health at the University of Arkansas.
Compared with participants who used less than 120 minutes per day of social media, for example, young adults who used more than 300 minutes per day were 2.8 times as likely to become depressed within six months.
Charles Darwin's landmark opus, On the Origin of the Species, ends with a beautiful summary of his theory of evolution, "There is a grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved." In fact, scientists now know that most species that have ever existed are extinct.
Researchers in South Korea have developed a technology that enables immediate detection of specific airborne viruses in the field. The Korea Institute of Science and Technology (KIST)
Researchers from Temple University, Tsinghua University, and Fudan University published a new paper in the Journal of Marketing that explores the business impact of PPI on buyers' purchase behaviors and sellers' sales activities.
A single protein that appears necessary for the COVID-19 virus to reproduce and spread to other cells is a potential weakness that could be targeted by future therapies.
The molecule, known as transmembrane protein 41 B (TMEM41B), is believed to help shape the fatty outer membrane that protects the virus' genetic material while it replicates inside an infected cell and before it infects another.
Protein therapies are often more potent and selective toward their biochemical targets than other types of drugs, particularly small molecules. However, proteins are also more likely to be quickly degraded by enzymes or cleared from blood by the kidneys, which has limited their clinical use. Now, researchers reporting in ACS Central Science have engineered red blood cell (RBC) carriers that release therapeutic proteins when stimulated by light, with the help of a honey bee peptide.
In a study of older adults admitted to the hospital with influenza and other acute respiratory illnesses during the 2011-2012 flu season, functional decline was common--and for some, this decline was persistent and catastrophic. The findings are published in the Journal of the American Geriatrics Society

Medicine misuse is a public health issue, but the term has different meanings to people in different settings. A recent analysis of published studies provides a comprehensive overview of the terms and definitions used to characterize medicine misuse. The findings are published in the British Journal of Clinical Pharmacology.
SAN ANTONIO - Early circulating tumor cell dynamics were associated with overall survival in patients with metastatic breast cancer, according to a meta-analysis presented at the 2020 San Antonio Breast Cancer Symposium, held Dec. 8-11.
SAN ANTONIO - A large meta-analysis of breast cancer survivors of childbearing age indicated that they are less likely than the general public to get pregnant, and they face higher risk of certain complications such as preterm labor. However, most survivors who do get pregnant deliver healthy babies and have no adverse effects on their long-term survival, according to data presented at the 2020 San Antonio Breast Cancer Symposium, held Dec. 8-11.
PORTLAND, Oregon | December 9, 2020 -- Across the North Pacific, salmon fisheries are struggling with climate variability, declining fish populations, and a lack of sustainable fishing opportunities. According to a study published today in BioScience from a team of Indigenous leaders and conservation scientists, help lies in revitalizing Indigenous fishing practices and learning from Indigenous systems of salmon management.
The observation of a chemical reaction at the molecular level in real-time is a central theme in experimental chemical physics. An international research team has captured roaming molecular fragments for the first time. The work, under the supervision of Heide Ibrahim, research associate at the Institut national de la recherche scientifique (INRS), was published in the journal Science.
Scientists have produced a tomato enriched in the Parkinson's disease drug L-DOPA in what could become a new, affordable source of one of the world's essential medicines.
The development of the genetically modified (GM) tomato has implications for developing nations where access to pharmaceutical drugs is restricted.
This novel use of tomato plants as a natural source of L-DOPA also offers benefits for people who suffer adverse effects - including nausea and behavioral complications - of chemically synthesised L-DOPA .
Bacteria is all around us--not just in bathrooms or kitchen counters, but also inside our bodies, including in tumors, where microbiota often flourish. These "small ecologies" can hold the key to cancer drug therapies and learning more about them can help development new life-saving treatments.
Researchers have discovered a new superhighway network to travel through the Solar System much faster than was previously possible. Such routes can drive comets and asteroids near Jupiter to Neptune's distance in under a decade and to 100 astronomical units in less than a century. They could be used to send spacecraft to the far reaches of our planetary system relatively fast, and to monitor and understand near-Earth objects that might collide with our planet.
