Obsessive-compulsive disorder (OCD) in children and adolescents is associated with impaired education and worse general health later in life. Access to specialist treatment is often limited. According to a study from Centre for Psychiatry Research at Karolinska Institutet in Sweden and Region Stockholm, internet-delivered cognitive behavioural therapy (CBT) can be as effective as conventional CBT. The study, published in the prestigious journal JAMA, can help make treatment for OCD more widely accessible.
This rare fossil find comes from the Kimmeridge Clay Formation in England, a series of sedimentary rocks that was formed in a shallow, tropical-subtropical sea during the Upper Jurassic, about 150 million years ago. The fossil shark skeleton was found more than 20 years ago on the southern coast of England and is now held in the Etches Collection. Additional fossil shark specimens from it will be investigated in the years to come.
Wastewater testing is an effective way to identify new cases of COVID-19 in nursing homes and other congregate living settings, and it may be particularly useful for preventing outbreaks in college dormitories, a new University of Virginia study finds.
The research, a collaboration of UVA's School of Medicine and School of Engineering, was led by UVA Health's Amy Mathers, MD. It offers some of the first clear guidance on the most effective methods to perform testing to detect COVID-19 in wastewater.
SASKATOON - Tepary beans--a high protein legume common to the southwest United States and Mexico--may hold the key to adapting bean crops for the increasingly harsh conditions brought on by a changing climate, according to research led by University of Saskatchewan (USask) and Michigan State University.
In a study just published in Nature Communications, the researchers found that as the mercury rises to 27oC at night--a temperature devastating for current bean crops--specific genes sensitive to heat stress in the tepary bean get activated, protecting the plant.
(Boston)--Chronic Obstructive Pulmonary Disease (COPD) is a disease caused by cigarette smoking that reduces lung function and causes difficulty breathing. It is the third leading cause of death worldwide. Current treatments for COPD only affect symptoms, not progression. Identifying who is going to get COPD before they get it is key to figuring out how to intercept the disease at an early stage.
Researchers have mapped out the changes in metabolism that occur after a heart attack, publishing their findings today in the open-access eLife journal.
Their study in mice reveals certain genes and metabolic processes that could aid or hinder recovery, and might be good targets for treatments to prevent damage after a heart attack.
A new study from the University of Chicago has found that the photosynthetic bacterium Synechococcus elongatus uses a circadian clock to precisely time DNA replication, and that interrupting this circadian rhythm prevents replication from completing and leaves chromosomes unfinished overnight. The results, published online on May 10 in Proceedings of the National Academy of the Sciences, have implications for understanding how interrupted circadian rhythms can impact human health.
Argonne scientists across several disciplines have combined forces to create a new process for testing and predicting the effects of high temperatures on refractory oxides.
Cast iron melts at around 1,200 degrees Celsius. Stainless steel melts at around 1,520 degrees Celsius. If you want to shape these materials into everyday objects, like the skillet in your kitchen or the surgical tools used by doctors, it stands to reason that you would need to create furnaces and molds out of something that can withstand even these extreme temperatures.
A new approach to road safety that relies on design and engineering principles--the "Safe System" approach--could lead to dramatic reductions in vehicle-related deaths and injuries if implemented in the U.S., according to a report from a consortium of experts convened by researchers at Johns Hopkins Bloomberg School of Public Health and the Institute of Transportation Engineers.
Amsterdam, May 11, 2021 - It is projected that up to 152 million people worldwide will be living with Alzheimer's disease (AD) by 2050. To date there are no drugs that have a substantial positive impact on either the prevention or reversal of cognitive decline. A growing body of evidence finds that targeting lifestyle and vascular risk factors have a beneficial effect on overall cognitive performance.
Study Take-Aways:
Different African populations were genetically interrelated suggesting abundant gene flow across Africa such that all African population should be considered together as single subspecies.
There appeared a striking genomic distance between leopards living in Asia vs. leopards in Africa.
Asian leopards are more genetically separated from African leopards than brown bear species are from polar bear species, the researchers found.
The two leopard groups actually diverged around the same time as Neanderthals split apart from modern humans.
It took an unlikely food innovation -- earth-friendly vegetarian patties, made to taste and "bleed" like the familiar meaty ones -- to make people aware of heme.
But heme is an essential part of proteins found in most life forms, from tiny bacteria to soy plants to the human body. Heme plays a crucial role in supplying cells with the energy needed to carry out chemical reactions.
ALBUQUERQUE, N.M. -- Two groups of researchers at Sandia National Laboratories have published papers on the droplets of liquid sprayed by coughs or sneezes and how far they can travel under different conditions.
Both teams used Sandia's decades of experience with advanced computer simulations studying how liquids and gases move for its nuclear stockpile stewardship mission.
Trinity study finds people homeless in their 20s, 30s and 40s are physically comparable to those housed in their 70s and 80s
