Taking vitamin D supplements could slow or even reverse the progression of less aggressive, or low-grade, prostate tumors without the need for surgery or radiation, a scientist will report today.
His team will describe the approach in one of nearly 11,000 presentations at the 249th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society. The meeting is being held here through Thursday.
When radiation suddenly contaminates the land your family has farmed and lived on for generations, you might not expect soil to protect crops and human health - that is like expecting the mugging victim to track down the criminal - but that is what happens.
On March 11th, 2011, twin perils of a magnitude 9.0 earthquake and tsunami caused widespread destruction in Japan, including peril at the Fukushima Daiichi nuclear power plant. The plant released radioactivity into the environment and the Japanese government evacuated over 100,000 people in the 30 kilometer zone around the plant.
Do you ever have trouble telling right from left? For example, you’re taking a driving lesson and the instructor asks you to take a left turn and you pause, struggling to think of which way is left.
If so, you’re not on your own – a significant proportion of our population has difficulty in telling right from left.
Mention the terms “intellectual giftedness” and “learning disability” and there is a general understanding of what each term means. However, most people are unaware that in many circumstances the two can go hand in hand.
Current US research suggests that 14% of children who are identified as being intellectually gifted may also have a learning disability. This is compared to about 4% of children in the general population. No-one has been able to explain this discrepancy.-->
The Fermi Paradox roughly states that: The universe is both
big enough and old enough to have birthed advanced civilizations.
Statistically, we are likely not the first. Far older super ETs should have left super artifacts around for us to find, by intention or not.
The observational evidence, however, strongly suggests otherwise.
For people taking glucocorticoids such as prednisone, the increased risk of bone fracture is a well-documented side effect. Used to treat a variety of medical conditions, including autoimmune diseases and allergies, glucocorticoids are known to cause rapid deterioration in bone strength.
Until now, doctors have been able to measure bone loss -- a process that happens slowly, over time -- but haven't had the means for gauging actual bone strength. That has changed thanks to a new hand-held instrument developed in the Hansma Lab at UC Santa Barbara. Called the OsteoProbe, the device uses reference point indentation (RPI) to measure mechanical properties of bone at the tissue level.
While many recent studies have documented that agricultural producers must significantly increase yields in order to meet the food, feed, and fuel demands of a growing population, few have given practical solutions on how to do this. Crop science researchers at the University of Illinois interested in determining and reducing corn yield gaps are addressing this important issue by taking a systematic approach to the problem.
Two-year data show a continued survival advantage for self-expanding transcatheter aortic valve replacement (TAVR) over standard surgery in high-risk patients with severe aortic stenosis, according to research presented at the American College of Cardiology's 64th Annual Scientific Session.
Aortic stenosis--a problem that occurs when the valve in the heart's main artery doesn't open fully--forces the heart to work harder to pump blood and is life-threatening over time. Valve replacement is common when this condition becomes severe, but the health profile of many patients makes standard surgical valve replacement especially risky.
A pair of air pollutants linked to climate change could also be a major contributor to the unparalleled rise in the number of people sneezing, sniffling and wheezing during allergy season. The gases, nitrogen dioxide and ground-level ozone, appear to provoke chemical changes in certain airborne allergens that could increase their potency. That, in combination with changes in global climate, could help explain why airborne allergies are becoming more common.
The findings will be presented today at the 249th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society. The meeting features nearly 11,000 reports on new advances in science and other topics. It is being held here through Thursday.
A new study adds fuel to the already hot debate about whether electric vehicles are more environmentally friendly than conventional vehicles by uncovering two hidden benefits.
They show that the cool factor is real - in that electric vehicles emit significantly less heat. That difference could mitigate the urban heat island effect, the phenomenon that helps turn big cities like Beijing into pressure cookers in warm months.
Moreover, the cooling resulting from replacing all gas-powered vehicles with electric vehicles could mean city dwellers needing less air conditioning, another environmental win.
Scientists have grown the first 3-D mini lungs from stem cells, which means research is one step closer to being able to create one of the Big 5 organs from a patient's stem cells rather than having waiting lists for donors.
The University of Michigan scientists succeeded in growing structures resembling both the large proximal airways and the small distal airways.
