Bioplastics are used in medical applications such as wound healing dressings, sutures, catheter tubes and drug delivery and bioplastics made from protein sources such as albumin and whey have shown significant antibacterial properties.
They could even be used for food packaging, according to a recent study
by the University of Georgia College of Family and Consumer Sciences.
In January of 2015 the European Food Safety Authority (EFSA) lowered the threshold value for bisphenol A in packaging. The scientific determination behind that is irrelevant at this point, the only times Europe backs off on bizarre science assertions are when it comes to things like making ugly fruit illegal to sell or claiming water does not cure thirst, so companies are stuck with creating dubious alternatives or just using less, but the public is often educated by advertising so they want less of it in the environment.
Our bodies do not absorb all of the medicines we might take, some are excreted and though the impact individually is minor, over time and in a large population, there are concerns that such medical waste will lead to issues like antibiotic resistance.
In 1996, the Nobel Prize for Chemistry went to the discoverers of Buckminsterfullerene; soccer-ball-shaped spheres of 60 joined carbon atoms that exhibit special physical properties colloquially called Buckyballs.
It was only a time before someone found a way to weaponize those, but in this case for the public good: Buckybombs. But these nanoscale explosives will target and eliminate cancer at the cellular level, triggering tiny explosions that kill cancer cells without affecting surrounding tissue.
Hydrazine was reported once in a limited sample of cigarette tobacco and tobacco smoke over 40 years ago but ever since then it has been assumed as fact that hydrazine must be present in smokeless tobacco products as well, without anyone actually examining those products for its presence.
Researchers trying to understand why some people have more severe wheat-related health problems than others, and with different products, have found new clues in how the grain's proteins, including gluten, change when cooked and digested.
Gianfranco Mamone and colleagues say that boiling pasta releases some of its potential allergens, while other proteins persist throughout cooking and digestion. Their findings lend new insights that could ultimately help celiac patients and people allergic to wheat.
A new injectable polymer
strengthens blood clots and that means that soldiers who might otherwise die from uncontrolled bleeding before reaching a surgical hospital could be saved. Likewise for civilian traumas.
A tourniquet won't stop bleeding from a chest wound, and clotting treatments that require refrigerated or frozen blood products aren't always available in the field.
Lighting technology is in a state of change. Incandescent bulbs, which have been around forever, have been banned in the United States but the heavily-subsidized replacement, compact fluorescent bulbs, run the risk of mercury poisoning if they break and have a glow that many don't find appealing. Light emitting diodes (LEDs) are likely the technology of choice in the mid-term future but they are expensive.

(Inside Science) -- Sampling the waste in a city's sewage system can be a good way to study the microbes that live in the population's guts – and could even offer a way to monitor public health issues such as obesity, according to new research.
I am writing a book on mitochondria and after a few months of research you begin to see a common thread - serendipity. Sometimes big things happen because of what seems to be luck, a group of people all happen to be in one place at one time, they are all spurred on by each other and then dramatic things occur.
