A new report finds about one in three cancer survivors (34.6%) reported having chronic pain, representing nearly 5.4 million cancer survivors in the United States. The report, appearing as a Research Letter in JAMA Oncology, finds one in six survivors (16%), representing about 2.5 million people in the U.S., reported suffering from high impact chronic pain that restricts daily functioning. Those rates are about double the rates in the general population.
Washington, DC, June 20, 2019- The development of neural circuits in youth, at a particularly important time in their lives, can be heavily influenced by external factors--specifically the frequent and regular use of cannabis.
Methods used to design F1 cars and spacecraft have played a crucial role in new research into the tags used to track animal movements.
Ecologists joined forces with aerospace colleagues at Swansea University to find the best way to reduce the drag of biologging tags - the recording devices used to track animal movements and behaviour.
Scientists at VCU Massey Cancer Center have discovered that the loss of a protein called DBC1 in breast cancer cells leads to the dysregulation of normal anti-cancer functions, contributing to cancer cell growth and resistance to therapies. By restoring the expression of this protein, doctors may be able to help prevent the development of cancer and increase the effectiveness of common cancer treatments.
With the number of children diagnosed with autism on the rise, the need to find what causes the disorder becomes more urgent every day. UCF researchers are now a step closer to showing the link between the food pregnant women consume and the effects on a fetus' developing brain.
A pioneering new study led by Florida State University biologists could fundamentally change our understanding of how embryonic stem cells differentiate into specific cell types.
The research, published today in the journal Stem Cell Reports, calls into question decades of scientific consensus about the behavior of embryonic stem cells as they transition to endoderm, a class of cell in animal embryos that gives rise to the digestive and respiratory systems.
A new MIT-developed technique enables robots to quickly identify objects hidden in a three-dimensional cloud of data, reminiscent of how some people can make sense of a densely patterned "Magic Eye" image if they observe it in just the right way.
The intestinal parasite Cryptosporidium, which causes a diarrheal disease, is very good at infecting humans. It's the leading cause of waterborne disease from recreational waters in the United States. Globally, it's a serious illness that can stunt the growth of, or even kill, infants and young children. And people with compromised immune systems, such as those with HIV/AIDS, are also highly susceptible. There is no vaccine and no effective treatment.
WASHINGTON -- High school seniors' confidence in law enforcement and the justice system significantly declined from 2006 to 2017 while their faith in religious organizations and schools was comparatively higher and more stable, according to research published by the American Psychological Association.
Young gay and bisexual men are frequent users of alkyl nitrites, or poppers, but few show signs of addiction, risky consumption habits or other psychosocial problems, a study shows.
A survey of more than 800 men aged 18 to 35 found little evidence of typical dependency characteristics, including health, social, legal and financial problems, and no correlation between popper use and mental health or psychological stress.
TORONTO, ON (Canada) - New research by cell biologists at the University of Toronto (U of T) provides significant new insight into the very first step stem cells go through to turn into the specialized cells that make up organs.
The findings published online in Genes & Development implicate the ability of proteins to hang around in cells - their stability - as a major factor in controlling a stem cell's state, and in the decision to remain a stem cell or transform into a specialized cell.
In a study published in the journal Nature, researchers identified 27 new genomic variants associated with conditions such as blood pressure, type II diabetes, cigarette use and chronic kidney disease in diverse populations. The team collected data from 49,839 African-American, Hispanic/Latino, Asian, Native Hawaiian, Native American and people who identified as others and were not defined by those ethnic groups. The study aimed to better understand how genomic variants influence the risk of forming certain diseases in people of different ethnic groups.
Every night while sleeping, we cycle between two very different states of sleep. Upon falling asleep, we enter non-rapid eye movement (non-REM) sleep where our breathing is slow and regular and movement of our limbs or eyes are minimal. Approximately 90 minutes later, how-ever, we enter rapid eye movement (REM) sleep. This is a paradoxical state where our breath-ing becomes fast and irregular, our limbs twitch, and our eyes move rapidly.
A growing population, rising standards of living and quickly changing fashions send mountains of clothing waste to the world's landfills each year. Although processes for textile recycling exist, they tend to be inefficient and expensive. Now, researchers have reported in ACS Sustainable Chemistry & Engineering an efficient, low-cost method that can convert waste denim into viscose-type fibers that are either white or the original color of the garment.
In nutrient-poor deep-sea sediments, microbes belonging to the Archaea have outcompeted bacterial microorganisms for millions of years. Their ability to efficiently scavenge dead cells makes them the basal producers in the food chain.
