Why do some children have more difficulties understanding others' emotions or feeling sorry after misbehaving? Why do some act out in certain situations and behave in others? How should adults respond in these circumstances?
For parents, such puzzles can seem unsolvable yet having insight into the inner workings of these situations becomes increasingly important when the behaviors start to interfere with daily functioning and healthy development.
Hunting wild animals has been practised by humans for millions of years; however, the extraction of wildlife for subsistence and commercialisation has become a major biodiversity threat in recent decades. Meanwhile, over-exploitation is reported to be the second most important driver of change and biodiversity loss globally.
Boston, MA -- Chemical compounds found in skin creams and other personal care products can cause an allergic reaction in the skin, a common condition known as allergic contact dermatitis (ACD). While ACD is on the rise, particularly in industrialized countries, exactly how personal care chemical compounds trigger a reaction remains unknown. Most allergic reactions involving T cells are attributed to proteins or peptide antigens that trigger the immune system.
On a hillside above Stanford University, the SLAC National Accelerator Laboratory operates a scientific instrument nearly 2 miles long. In this giant accelerator, a stream of electrons flows through a vacuum pipe, as bursts of microwave radiation nudge the particles ever-faster forward until their velocity approaches the speed of light, creating a powerful beam that scientists from around the world use to probe the atomic and molecular structures of inorganic and biological materials.
A study out of the University of Hyogo in Awaji, Japan, details the stress-reducing benefits to office workers that even a small plant situated within easy viewing can impart.
Masahiro Toyoda, Yuko Yokota, Marni Barnes, and Midori Kaneko explored the practical use of indoor plants to boost mental health among employees typically removed from exposure to healthy green environments.
Clostridium Difficile (C. diff) is a virulent health care-associated infection responsible for nearly 13,000 deaths and over $5 billion in health care related costs annually in the U.S.
Overuse of antibiotics has helped spread C. diff, one of the most difficult to treat bacterial infections.
The Atlantic Multidecadal Oscillation (AMO) and the Pacific Decadal Oscillation (PDO) do not appear to exist, according to a team of meteorologists who believe this has implications for both the validity of previous studies attributing past trends to these hypothetical natural oscillations and for the prospects of decade-scale climate predictability.
The world scientific community is waging a difficult and prolonged war on cancer. New research in the field of immunogenic cell death can extend the area of drugs application and ensure patients' protection from relapse after therapy.
Cancer treatment is not just the removal of the tumor cells from the body, and chemotherapy. The doctors' aim is to provide a scenario that would prevent tumor cells from proliferating and causing a new disease.
January 3, 2020 -- In an invited Commentary just published in JAMA Internal Medicine, Columbia Mailman School of Public Health professors Drs. Steven Stellman and Jeanne Mager Stellman offer their perspective on results from a recent study on Pyrethroid, among the most widely used insecticides in the world for public health control of vector-borne illnesses, including West Nile virus.
ROCHESTER, Minn. -- Cardiorespiratory exercise -- walking briskly, running, biking and just about any other exercise that gets your heart pumping -- is good for your body, but can it also slow cognitive changes in your brain?
A study in Mayo Clinic Proceedings from the German Center for Neurodegenerative Diseases provides new evidence of an association between cardiorespiratory fitness and brain health, particularly in gray matter and total brain volume -- regions of the brain involved with cognitive decline and aging.
Testicular cancer can be prevented from coming back using half the amount of chemotherapy that is currently used, a new clinical trial has shown.
In many men who have had surgery for an aggressive form of testicular cancer, the disease can come back elsewhere in their bodies and need intensive treatment, often within two years after initial diagnosis.
The new trial showed that giving men one cycle of chemotherapy was as effective at preventing men's testicular cancer from coming back as the two cycles used as standard.
(Boston)--While the average American woman's waist circumference and dress size has increased over the past 20 years, Victoria's Secret fashion models have become more slender, with a decrease in bust, waist, hips and dress size, though their waist to hip ratio (WHR) has remained constant.
These findings represent an ideal of beauty that continuously moves further away from the characteristics of the average American woman.
Supplementing the body's short chain fatty acids can improve stroke recovery, according to research in mice recently published in JNeurosci. Short chain fatty acid supplementation may be a non-invasive addition to stroke rehabilitation therapies.
The gut microbiome influences brain health, including how the brain recovers from stroke. Short chain fatty acids, a fermentation product from the bacteria in our guts, are a key component of gut health but their role in stroke recovery has not been explored.
Bariatric surgery is associated with a distinct reduction in skin-cancer risk, a study shows. This finding can be described as a key piece of evidence that substantiates the connection between weight loss and malignant skin cancer.
"This provides further evidence for a connection between obesity and malignant skin cancer, and for the view that we should regard obesity as a risk factor for these forms of cancer," says Magdalena Taube, the first author behind the study and a researcher in molecular and clinical medicine at Sahlgrenska Academy, University of Gothenburg, Sweden.
The reconstitution of the blood system in humans holds great therapeutic potential to treat many disorders, like blood cancers, sickle-cell anemia and others. Successful reconstitution requires the transplantation and engraftment of hematopoietic (or blood) stem cells (HSCs), which after reaching their niche, start producing all types of blood cells, including platelets, white and red blood cells.
