MD Author Information Division of Vascular Surgery, NYU Winthrop Hospital, Mineola, New York The author has no conflicts of interest to report.

Sience
China and the lingua Franca of science The word for ‘science’ in Chinese today is no longer ‘gézhì (格致),’ but the imported Japanese word ‘kēxué (科学)’. The switch reflects the “loss and shame” that followed the Chinese defeat in the Sino-Japanese War and heralds the attempt to forge a new Chinese identity, writes particle physicist Yangyang Cheng. Later, English became a language that begat both freedom and persecution for Chinese scientists. “Like the French syllables attached to polynomials and the German surnames associated with quantum mechanics, even when describing universal law... mais »
Neanderthal–Denisovan hybrid
FEATURES & OPINION The cave where human history was rewritten Denisova Cave in southern Siberia was once home to modern humans, Neanderthals and a mysterious group of extinct humans known as Denisovans. The cave yielded a single finger bone that revealed the Denisovans and a “one-in-a-million find” of a first-generation Neanderthal–Denisovan hybrid. Now, almost a decade after the discovery, scientists are gaining confidence that they will soon uncover more Denisovan remains from sites in China and beyond — if they haven’t already.

Periodic Table
150 years of the periodic table [image: Mendeleev stamp] Assembling atoms An element is defined by the number of protons it contains. Create an atom with more protons than ever before, and you’ve got yourself a brand new element. Each element comes in a variety of types, known as isotopes, distinguished by the number of neutrons in the nucleus. Changing the number of neutrons in an atom’s nucleus alters the delicate balance of forces that makes a nucleus stable or that causes it to decay quickly. Different isotopes of an element might have wildly different half-lives, the period of ...mais »

Sweets and Stress
Why Do We Crave Sweets When We're Stressed? A brain researcher explains our desire for chocolate and other carbs during tough times Achim Peters Although our brain accounts for just 2 percent of our body weight, the organ consumes half of our daily carbohydrate requirements—and glucose is its most important fuel. Under acute stress the brain requires some 12 percent more energy, leading many to reach for sugary snacks. Carbohydrates provide the body with the quickest source of energy. In fact, in cognitive tests subjects who were stressed performed poorly prior to eating. Their perfor... mais »

Forgetting
INFOGRAPHIC Infographic: Science behind forgetting Unless you have a photographic memory, you likely find it hard to remember everything you learn, even an hour or two after you learn it. Why? Research about how we remember and forget gives us a clue. 19th century psychologist Hermann Ebbinghaus created the “Forgetting Curve” after studying how quickly he learned, then forgot, a series of three-letter trigrams. Here’s what he discovered: Our brains are hardwired to recall important facts. The process that determines what you remember and what you forget makes recalling every single d... mais »

Dark Matter and Energy
Our entire cosmic history is theoretically well-understood, but only qualitatively. It’s by observationally confirming and revealing various stages in our Universe’s past that must have occurred, like when the first stars and galaxies formed, that we can truly come to understand our cosmos. The temporal origin of dark matter and dark energy have constraints, but an exact time-of-origin is unknown.
