Researchers Use Light to Switch On Gene Expression

Imagine being able to control genetic expression by flipping a light switch. Researchers at North Carolina State University are using light-activated molecules to turn gene expression on and off. Their method enables greater precision when studying gene function, and could lead to targeted therapies for diseases like cancer. Triplex-forming oligonucleotides (TFOs) are commonly used molecules…

Why Does Water Freeze Before Alcohol Does?

We recently explained that one reason wine’s freezing point is much lower than water’s is because of its alcohol content. But we didn’t explain why alcohol has a much lower freezing point than water. Let’s explain that now (hint: water molecules are “stickier.”) A substance freezes when its molecules become “stuck” in a fixed array…

Why Doesn’t Wine Freeze? And Do Vacuum-Sealing Stoppers Keep Wine ‘Fresh’?

I set out to learn why wine doesn’t freeze. But while I was questioning a wine researcher, I thought I’d also find out whether those vacuum-sealing wine stoppers are worth it. Here’s what I found out. Question 1: Why Doesn’t Wine Freeze? Wine will freeze, it just has a much lower freezing point than water…
