In the world of Harry Potter, one’s memory can be manipulated with the flick of a wand. Albus Dumbledore reels wispy memories out of his head and puts them in a Pensieve. If he later dunks his head in that magical basin, he can see his past experiences with lifelike clarity. Hermione Granger, meanwhile, uses the spell “Obliviate” to remove herself from her parents’ memories to protect them from the wizarding world. In real life, memories are not storable liquids or files that can simply be deleted.

About 18 years ago, a 4-year-old girl with a rare nerve cell cancer received an infusion of immune cells that were genetically engineered to fight the disease. Since then, she has remained cancer-free, possibly making her the longest-surviving patient with cancer who received this tailored treatment, researchers report February 17 in Nature Medicine.

From tracing the origins of glow-in-the-dark animals to developing the world’s fastest microscope, these superlative feats captured our imagination. Some 2.5 million years ago, an asteroid combusted in Earth’s atmosphere before it could hit the ground and leave a crater, making the event the oldest known midair explosion. That conclusion is based on a chemical analysis of nearly 120 microscopic rocks buried deep underneath Antarctic ice.
