Blood Test for Alzheimer’s

Earlier this week, a paper was published showing how, for the first time, a blood test may be used to predict whether a person will develop Alzheimer’s in the near future. Specifically, the blood test was able to predict with accuracy greater than 90% whether a person (70-years-old or older) would develop amnesic mild cognitive … Continue reading »

H7N9: Pandemic Potential?

A Chemical Way to Reverse Aging?

Is there a way to reverse aging? It’s the stuff that legends and myths are made of – the ever-elusive Fountain of Youth. But a paper published a few days ago in the prestigious journal Cell might make reversible aging closer to a reality (but it is still probably a long ways off). Specifically, by … Continue reading »

It’s That Time Again – the Flu Season’s Here

It’s long been hard for people to accept that they can be hurt, or even killed, by something they cannot see.

We don’t usually think about them unless something goes wrong, and, honestly, we don’t know a whole lot about them. But we’re learning. And as our understanding improves, we’re increasingly finding that these bacteria, yeast, and other … Continue reading »

A solution that increasing numbers of people turn to if they want to have a biological child is in vitro fertilization (IVF). About one million people in the U.S. seek fertility treatment of … Continue reading »

Genetically Modified Microbes

When thinking of genetically modified organisms (GMOs), plants and animals are probably the first to come to mind, which overlooks possibly the most important group of all: GM microorganisms, or microbes. It was in the 1970s that the first GMO was made – it was bacteria (specifically E. coli). A few years later, researchers were … Continue reading »

The Future of Clothing – Making it “Biofunctional”

For thousands of years, clothing has served obvious functions – it protects us from the elements (keeping us warm when it’s cold out, preventing sunburn, keeping us dry when it rains, etc.) and from injury during physical activities. We’ve even made it have more specialized functions, such as protecting us from hazardous chemicals, weapons, honey … Continue reading »
