Researchers propose air conditioners as climate-change remedy

Scientists have an idea that could make you feel more like a green citizen than hedonist if you buy an air conditioner for your living quarters. There is a way that could use the units to fight climate change. OK, let us review the question posed by a Fast Company: What if every air conditioner was stopping climate change as it kept you cool?"

Intelligence can link to health and aging

For over 100 years, scientists have sought to understand what links a person's general intelligence, health and aging. In a new study, a University of Missouri scientist suggests a model where mitochondria, or small energy producing parts of cells, could form the basis of this link. This insight could provide valuable information to researchers studying various genetic and environmental influences and alternative therapies for age-related diseases, such as Alzheimer's disease.

Design flaws create security vulnerabilities for 'smart home' internet-of-things devices

Researchers at North Carolina State University have identified design flaws in "smart home" Internet-of-Things (IoT) devices that allow third parties to prevent devices from sharing information. The flaws can be used to prevent security systems from signaling that there has been a break-in or uploading video of intruders.

Researchers make transformational AI seem 'unremarkable'

Physicians making life-and-death decisions about organ transplants, cancer treatments or heart surgeries typically don't give much thought to how artificial intelligence might help them. And that's how researchers at Carnegie Mellon University say clinical AI tools should be designed—so doctors don't need to think about them.

Understanding the power of honey through its proteins

Honey is a culinary staple that can be found in kitchens around the world. Humans have used honey throughout history, and its long shelf life and medicinal properties make it a unique, multipurpose natural product. Although it seems that a lot is known about the sweet substance, surprisingly little is known about its proteins. Now, researchers report in ACS' Journal of Natural Products new data on honey proteins that could lead to new medicinal applications.

Fighting food waste by finding ways to use the useless

Every Thursday and Sunday I walk my frozen banana peels and carrot tops to Columbia's farmers market. It's my small effort to combat food waste, which happens from production to retail to consumption. At the production level, farmers cannot always sell their produce due to surplus. Produce makes it to the retail level can end up being wasted due to imperfections and oversupply. And as consumers, our eyes are often bigger than our stomachs. This leads to a large amount of food being tossed into the garbage. Even though this food is never eaten, the carbon emissions to grow it still end up in the atmosphere and resources are still wasted. Reducing waste at each of these levels is crucial to fighting climate change.
