Current Events in the World of Chemistry

• Can Chemically Enhanced Tomatoes Taste Even
  Better Than Their All-Natural Counterparts?
  Research being conducted is producing what many
  believe are better-tasting, more flavorful
  tomatoes in light of the oncoming summer months.
• Cyropreservation Can people be frozen and
  preserved without producing potentially damaging
  ice crystals? Well take a closer look later.
