After decades of public safety campaigns focused on drinking and driving, it may be time to focus on the seventh leading cause of injury-related death, according to Bureau of Occupational Health and Injury Prevention at New York State Department of Health and Columbia University scholars looking at New York State.
Our sun is constantly changing. It goes through cycles of activity - swinging between times of relative calm and times when frequent explosions on its surface can fling light, particles and energy out into space. This activity cycle peaks approximately every 11 years. New research shows evidence of a shorter time cycle as well, with activity waxing and waning over the course of about 330 days.
Space science missions are a lot like smartphones. News apps and operating systems may not be compatible with older hardware and vice-versa.Different data processing protocols of individual space missions has limited comparison of data from numerous space missions. Due to the complexity of space exploration, instruments and devices are usually purpose-made and data acquisition as well as number crunching tools are built using mission specific data structures and protocols. The downside: the exchange and comparison of observational data between missions and complex computational models developed by third parties are virtually impossible.
Cancer researchers have identified a key signaling pathway in B-cell lymphoma, a malignant type of blood cancer. They demonstrate that the signaling pathway can be blocked using compounds that are already in clinical development.
The shorter you are, the more your risk of coronary heart disease, according to a new study. Every 2.5 inches change in height affected your risk of coronary heart disease by 13.5 percent - so a 5 foot 6 inch tall person has a 32% lower risk of coronary heart disease than a 5 foot tall person because of the latter's shorter stature.
Coronary heart disease is the commonest cause of premature death worldwide. It is the condition where the arteries that supply blood to the heart muscle (coronary arteries) become narrowed due to a deposition of fatty material (plaque) in the walls of the arteries. If a blood clot forms over the plaque then the artery can become completely blocked suddenly giving rise to a heart attack.
Scientists have identified a small RNA molecule named miR-182 that can suppress cancer-causing genes in mice with glioblastoma mulitforme (GBM), a deadly and incurable type of brain tumor.
There are 16,000 new cases of the deadly brain tumor reported in the U.S. every year. Patients have a very poor prognosis, with median survival of just 14 to 16 months.
Standard chemotherapy drugs stop cancer cells from reproducing by damaging DNA but the new method instead stops the source that creates those cancer cells: genes that are overexpressing certain proteins.
Carbon capture could play a central role in keeping greenhouse gas emissions out of the atmosphere so many materials are being tested for the purpose of capturing CO2. New results show that ordinary clay can work just as effectively as more advanced materials. Clay offers many benefits compared to other materials, particularly because other potential materials can be expensive, difficult to produce, toxic and not particularly environmentally friendly. A possible practical future use of this discovery could be to include clays in CO2 filters for industrial-scale CO2 emissions reduction.
Thermochromic nano-coatings can help reduce energy usage and generate savings by absorbing heat or permitting its reflection, depending on temperature. The reasn is because minute dimensions can still have major effects - nanoparticles have an especially large surface-area-to-volume ratio, making them them extremely efficient and reactive. Researchers of the Fraunhofer Institute for Chemical Technology ICT in Pfinztal near Karlsruhe are utilizing this characteristic to create novel coatings and incorporating active nano-materials into polymer systems. These coatings can be applied easily like paint or varnish.
In the developed world, we are aging rapidly. People age 85 and older make up the fastest growing age group in the United States and in other countries that trend will also increase.Aging and aging well are not always the same thing, though, and issues like Alzheimer's are a concern. A new study of 256 people with an average age of 87 who were free of memory and thinking problems at the start of the study concluded that who participate in arts and craft activities and who socialize may delay the development in very old age of the thinking and memory problems that often lead to dementia.
Children who play a game together have a stronger connection than kids who play the same game but not in a synchronous way, according to a new paper. The authors assert that a physical activity performed in unison helps children feel more positively toward each other and could perhaps increase their empathy. "Synchrony is like a glue that brings people together -- it's a magical connector for people," said lead author Tal-Chen Rabinowitch, a postdoctoral fellow at the Institute for Learning&Brain Sciences at the University of Washington.
An analysis of 22 years of data on hawksbill turtles in the Arnavons, located in the Solomon Islands, shows signs of recovery after 150 years of excessive hunting by natives. The data included both beach counts and turtle tagging data and show a 200% increase from record lows in the 1990s, when the turtles had been hunted to the brink of extinction. Many of the hawksbill turtles that nest at the Arnavon Community Marine Conservation Area forage in distant Australian waters, and nesting on the Arnavons occurs throughout the year, with peak nesting activity coinciding with the austral winter.

A new review of existing studies suggests a gradual, prolonged release of greenhouse gases from permafrost soils in Arctic and sub-Arctic regions.That sounds like bad news, and it is, but the good news is it actually means more time to adjust to ways to reduce emissions and prevent it from happening at all. In the original global warming scenarios, climate scientists contended that as permafrost thawed, carbon would be released in a big “bomb” and significantly accelerate climate warming. But a gradual case means more time to fix things.
Are the building blocks of life universal?Astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disc surrounding a young star named MWC 480. That means the conditions that spawned the Earth and Sun are not unique in the Universe.
