Beer on my Beef Please

By: Kate M. Serrano

Nothing beats a cold bottle and a hot steak on the grill. What’s more cool is pouring the cold one on your meat before grilling also has a positive effect on health.

Using beer as flavor base of marinade dates back to the old Egyptian and Mesopotamian days. Both civilizations are advanced and archaeological evidence suggests their cuisine was rich and flavourful. A tough steak can be extremely difficult to chew. Beer allows you to enjoy the once tough leaner cuts as its alcohol content helps tenderize the meat by breaking down its proteins. The longer the steaks marinate in beer, the more meat proteins dissolve, and the more tender the steaks become.  Plus, the beer combined with citrus juices or vinegar will make the tenderizing process faster than with just the beer alone. Of course beer marinade doesn’t only work on steak and meat. Wheat or white beers can be used to steam hot dogs or to base sauces for steaks. Also, flavoured beers like apricot or lime are good choices when paired with sauces or marinades of the same flavor.

And here is the good part. According to the American Chemical Society’s Journal of Agricultural and Food Chemistry, marinating with beer reduces polycyclic aromatic hydrocarbons (PAHs). These are the deadly carcinogens that form on meat cooked on a grill or barbeque. Limited exposure to PAHs mean limited exposure to cancer. In an experiment conducted by researchers, they found that dark beers reduced net PAHs by 53 percent. This is twice the effect compared to results from a non-alcoholic pilsner, which reduced only 25 percent.


So next time you plan on a barbeque party, keep in mind that beer-bathed pork and beef may look as healthy as it tastes. Just make sure not to drink the marinade.

How the Element Californium Could Change the World



By: Jessica Robertson

Californium (Cf) has not been thought to be one of the most glamorous elements of the periodic table, but that could soon be a different story thanks to a team of chemists at Florida State University. Their careful research has shown californium to have an uncanny ability to bond and separate other materials, all the while being highly resistant to any radiation damage. The lead researcher has called it “almost too good to be true,” and “wicked stuff,” after seeing the exciting qualities of the previously unimpressive element.
            The real-world application of such findings could entirely shift the scientific paradigm in the realm of nuclear chemistry. Storage containers built of californium could safely hold radioactive waste, while other californium based methods could be used to separate radioactive fuel, meaning the radioactive fuel could be recycled.

            Currently, the cost of californium is extremely high, but its promising ability to overcome the problem of nuclear waste in our world makes this research an entirely worthwhile pursuit.
