Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) and Very Long Baseline Array (VLBA) have found and studied the most distant cosmic jet discovered so far -- a jet of material propelled to nearly the speed of light by the supermassive black hole in a quasar some 13 billion light-years from Earth. The quasar is seen as it was when the universe was only 780 million years old, and is providing scientists with valuable information about how galaxies evolved and supermassive black holes grew when the universe was that young.
DALLAS, March 8, 2021 - While most people think of strokes affecting the brain, they can also affect the eye. Central retinal artery occlusion (CRAO) is a rare form of acute ischemic stroke that occurs when blood flow is blocked to the main artery of the eye. It typically causes painless, immediate vision loss in the impacted eye, with fewer than 20% of people regaining functional vision in that eye.
COLUMBUS, Ohio - Multinational companies headquartered in countries with tougher environmental policies tend to locate their polluting factories in countries with more lax regulations, a new study finds.
While countries may hope their regulations will reduce emissions of carbon dioxide and other greenhouse gases, these results show that these policies can lead to "carbon leakage" to other nations, said Itzhak Ben-David, co-author of the study and professor of finance at The Ohio State University's Fisher College of Business.
Philadelphia, March 8, 2021 - Virtual reality avatar-based coaching shows promise to increase access to and extend the reach of nutrition education programs to children at risk for obesity, according to a new study in the Journal of Nutrition Education and Behavior, published by Elsevier.
Suicide is the second leading cause of death among youth aged 5 to 21 years in the United States. Between 2010 and 2019, suicide rates among this group increased 40%.
Youth involved in the child welfare system experience an even greater risk of suicidal behavior, yet research on this vulnerable population is minimal.
A new data-driven study from Texas A&M University casts serious doubt on the stereotype that male students perform better than female students in science -- specifically, physics.
A team of researchers in the Department of Physics and Astronomy analyzed both the midterm exam scores and final grades of more than 10,000 Texas A&M students enrolled in four introductory physics courses across more than a decade, finding no evidence that male students consistently outperform female students in these courses.
Exercise has long-been recommended as a cognitive-behavioral therapy for patients of depression, yet new evidence from the University of California of San Diego suggests that the COVID-19 pandemic changed the nature of the relationship between physical activity and mental health.
In a study of college students conducted before and during the pandemic, findings revealed the average steps of subjects declined from 10,000 to 4,600 steps per day and rates of depression increased from 32% to 61%.
During the first half of 2020, the U.S. Intermountain West region of the United States experienced four significant earthquake sequences, spanning multiple states. In the new issue of SRL, 15 papers characterize these major earthquakes and discuss how they are helping seismologists gain new insights into the tectonics of the region.
Most people have heard of stem cells, cells from which all other cells with specialized functions are generated. Hematopoietic stem cells (HSCs) are the architects of blood cell development and are responsible for blood cell formation throughout the life of an organism. HSCs are also used in the treatment of cancer and immune disturbances.
SMU Office of Research and Tech Transfer - One of the motivations for the recently published Journal of Accounting Research paper "Politically Connected Governments" was the daily experience with the subway system in New York City.
Since the start of the Covid-19 pandemic, charts and graphs have helped communicate information about infection rates, deaths, and vaccinations. In some cases, such visualizations can encourage behaviors that reduce virus transmission, like wearing a mask. Indeed, the pandemic has been hailed as the breakthrough moment for data visualization.
SMU Office of Research & Tech Transfer - Even before countries began rolling out their vaccination campaigns, Pfizer, Moderna and AstraZeneca's announcements had already proved fortifying shots. Stocks rallied and healthcare workers celebrated in the wake of the vaccine news late last year. But months on, that early euphoria has somewhat evaporated, replaced by uncertainty and debate over vaccine safety, possible side effects and varying degrees of citizen reluctance.
DURHAM, N.C. -- When you think about what separates humans from chimpanzees and other apes, you might think of our big brains, or the fact that we get around on two legs rather than four. But we have another distinguishing feature: water efficiency.
That's the take-home of a new study that, for the first time, measures precisely how much water humans lose and replace each day compared with our closest living animal relatives.
Using genetic engineering, researchers at UT Southwestern and Indiana University have reprogrammed scar-forming cells in mouse spinal cords to create new nerve cells, spurring recovery after spinal cord injury. The findings, published online today in Cell Stem Cell, could offer hope for the hundreds of thousands of people worldwide who suffer a spinal cord injury each year.
In order to stay alive, the cell must provide its various organelles with all the energy elements they need, which are formed in the Golgi apparatus, its centre of maturation and redistribution of lipids and proteins. But how do the proteins that carry these cargoes - the kinesins - find their way and direction within the cell's "road network" to deliver them at the right place?
