Scientists have found the balance necessary to aid healing with high-tech hydrogel.

Hydrogels are used as a scaffold upon which cells can build tissue. The new hydrogel overcomes a host of issues that have kept them from reaching their potential to treat injuries and forming new vasculature to treat heart attack, stroke and ischemic tissue diseases.

Dust from soil erosion due to wind can affect human health, traffic, and, on a larger scale, climate. Investigators compared different models that quantify how the wind energy spreads over an herbaceous surface using data from the Sahel region of Africa, where estimates of dust emissions remain uncertain.

They found that the modeling tools give results in reasonable agreement, indicating that vegetation can decrease the amount of dust emitted from soil erosion by 6% to 26% in mass compared with bare soil.

Do consumers make different choices based on the fragrance surrounding them?  If they do not, a billion dollar advertising segment would disappear. Studies have found, for example, that lavender is the fragrance of trust and groups are always working to improve the ambiance of the marketplace. 

A new study in the Journal of Marketing says that the “temperature” of scents in a store atmosphere may have a powerful effect on what and how much customers buy. So if you want people to spend money, spread the cinnamon around.

Human papillomavirus is a virus that is responsible for almost all cases of cervical cancer and the HPV vaccine can prevent 70 percent of those.

A new study by University of Texas Medical Branch at Galveston researchers indicates that only about half of the girls ages 11-12, the age recommended by the Centers for Disease Control, receive the vaccine.

It's become a fad for nutritionists to claim that oranges are better than orange juice, and they list numerous reasons - from added sugar in juice to better uptake of carotenoids, flavonoids and Vitamin C in whole oranges.

But how different are they? Unless you are someone on a nutrition website selling the lifestyle and health fad of the moment, not much. It is true that some juices have more sugar but that is offset by the biological fact nutrients in orange juice seem to be easier for the body to absorb from juice than when a person consumes them from unprocessed fruit. 

And there is convenience. It is better to have a health benefit from something than no health benefit at all.

There are tens of thousands of human-made chemicals circulating today and some have been bad despite studies that didn't initially find harm, yet almost every chemical is under siege by environmental groups, and they all claim science is on their side.

Everything from bisphenol A used in plastics to neonicotinoid pesticides to glyphosate weed-killers are criticized by lawyers at environmental groups despite the science consensus. How can the public know which ones really pose threats to our health and environment and which ones are just studies designed to keep poisoning lab animals until they show an effect?
