There are two key characteristics of arctic berries that make them desirable for the skin: essential fatty acids (EFAs) and antioxidants. "Berry seeds contain both types of essential fatty acids that are needed by human beings," explains Baoru Yang, of Aromtech Ltd. in Finland, referring to linoleic acid, or omega-6, and alpha-linolenic acid, or omega-3. "This is a very rare case. In most plant oils you have only one type of EFA, and then the other type is missing or too low." More than just maintaining and moisturizing the lipid-rich epidermis, EFAs work to lighten...
...Cech examined a one-cell organism to study strands of ribonucleic acid, or RNA. Specifically, he investigated RNA splicing, in which cells convert long RNA strands into shorter ones, removing unneeded stretches. It was previously thought that enzymes catalyzed the cutting and reassembling process, and that RNA itself played a more passive role...
...took Leipold eight years and all €1.5 million of the family's money to perfect the recipe. Leipold found a way to ferment a nonalcoholic drink by converting the sugar that normally becomes alcohol into nonalcoholic gluconic acid. And because the acid strengthened the taste of sugar, Leipold only needed a fraction of the sugar found in a normal soft drink. Then came the flavors - elderberry, lychee, orange-ginger and herb - plus a spritz of carbonation...
...nature to anthropomorphize other life forms, even though they are only 200 nanometers wide. That is the width of newly discovered microbes that may be the smallest form of cellular life, according to a story in the New York Times this week. In "drainage water as caustic as battery acid," these hard-ass teeny-weenies have the flair to form "a pink scum on green pools...
...part by causing blood to clot abnormally. A small emergency-room study found that drugs used to break up clots may help revive cardiac-arrest patients when such methods as CPR and electrical shock have failed. There were murkier findings regarding people with high levels of homocysteine, an amino acid linked to heart disease. Folic acid and B vitamins help bring homocysteine down, but one study cast doubt on whether this actually improves heart health...
