Light as Medicine — and a Safety Challenge You may have seen the headline: “LED light can kill cancer cells.” It sounds futuristic — shining light on a tumor instead of blasting it with radiation or flooding it with chemotherapy. But this idea isn’t fantasy. It’s called photodynamic therapy (PDT) — and it’s a real area of cancer research that’s gaining traction

When “Safe” Products Become a Safety Lesson The U.S. Food and Drug Administration (FDA) recently announced a recall of several cholesterol-lowering medications after routine testing detected nitrosamine impurities — chemicals that can increase cancer risk following long-term exposure. For patients, the immediate health risk is low.
For scientists, regulators, and developers, however, this is a powerful reminder:

The procedure may be planned ahead of time, or it may be done during an emergency (temporary pacemaker). You will be given medicine to make parts of your body numb or make you sleep during the procedure. You may receive antibiotics to prevent infection and blood thinning medicine to prevent blood clots during the procedure. Different types of pacemakers require different procedures to place them.

NASA Confirms Earth Now Has Two Moons — And What That Teaches Us About Toxicology and Product Design
A Second Moon and a Second Look at Science NASA recently confirmed that Earth has a temporary second moon — a quasi-satellite that will orbit alongside us until 2083. This cosmic hitchhiker, roughly the size of a car, doesn’t replace our familiar Moon — but it does remind us of something profound about science: The systems we think we understand can always surprise us.
