<p>Our multiverse, hurricane names and gender bias and a beached whale hidden in a painting — just a few of our favorite stories in Science this week.</p><p>Click on!</p>
<p>The Solar Impulse 2, an aircraft powered entirely by the sun, successfully completed its maiden voyage today (June 2).
</p><p>The plane launched soon after sunrise from the Payerne Air Base in northern Switzerland, trailed by a helicopter that recorded its flight. Pilot Markus Scherdel flew the experimental, single-seater craft for 2 hours and 17 minutes, before landing it successfully. The ultimate goal is to fly the solar plane around the world, said Solar Impulse CEO André Borschberg.</p><p>[Full Story: <a href="http://www.livescience.com/46038-solar-impulse-2-maiden-voyage.html" target="_blank">'Round-the-World' Solar Plane Takes First Flight</a>]</p>
<p>In both the Bible and magical folklore, power over a man comes from knowing his true name: Speak it and strike him dead. Names carry savage clout in everyday life too, as anyone with parents cruel enough to name them Adolph or Bertha can attest.
</p><p>Now, a controversial new study suggests gender bias can shape how people respond to hurricane names.</p><p>[Full Story: <a href="http://www.livescience.com/46044-hurricane-names-gender-bias-deaths.html</a>]</p>
The end of an era
<p>Centenarians, people 100 years or older, are more likely to die of pneumonia or as a result of frail health than from cancer or heart disease, compared with "younger" elderly adults, according to the results of a new study.
</p><p>The study also revealed that people who reach their 100th birthday and beyond were most likely to die in a residential care home (61 percent) or hospital (27 percent), and less likely to die at home (10 percent) or in hospice (0.2 percent), said Catherine Evans, clinical lecturer on palliative care at King's College London, one of the study's authors.</p><p>[Full Story: <a href="http://www.livescience.com/46082-centenarians-what-they-die-of.html" target="_blank">Centenarians: Study Reveals What They Die of, and Where</a>]</p>
Keeping it cool
<p>The mention of a koala bear often conjures up an image of an adorable spoon-nosed creature cocking its head to one side while clinging to a tree.
</p><p>Now, scientists have figured out why the iconic Australian marsupials hug trees: The trunks help the koala bears keep cool, according to a new study.

How would we know?
<p>Some theories in physics give rise to the idea of multiple universes, where nearly identical versions of the known universe exist. But if such a multiverse does exist, how would people know, and what would it mean for humanity?
</p><p>There may be ways to find out if the known universe is one of many, said Brian Greene, a theoretical physicist and author at Columbia University in New York.

Some negative effects
<p>Many people think that smoking pot is harmless, but there's good evidence that the drug has at least some negative effects on health, a new review says.
<p></p>Some people who smoke marijuana can become addicted, and use of the drug in the teen years has been linked with abnormalities in certain brain areas important for learning and memory, the review said. And even the immediate short-term effects of the marijuana, such as impaired thinking and coordination, can have consequences, including difficulty in learning in school and an increased risk of car accidents, the review said.</p><p>[Full Story: <a href="http://www.livescience.com/46114-marijuana-health-effects.html" target="_blank">How Marijuana Affects Health</a>]</p>
<p>When art conservators in the United Kingdom were cleaning a 17th-century Dutch seascape, they found a surprise: an image of a beached whale that had been hidden for at least 150 years.
</p><p>Until recently, the painting — "View of Scheveningen Sands," created by Hendrick van Anthonissen around 1641 — simply showed groups of people gathered on a beach in The Hague in the Netherlands.

A worm lizard
<p>They look like snakes, but don't be fooled: Legless, slithering amphisbaenians are more closely related to lizards than to boa constrictors.
</p><p>Now, the first complete skull of the ancestor of today's bizarre "worm lizards" reveals that these strange reptiles have been largely unchanged for at least 11 million years. The fossil skull, discovered in Spain, is only 0.44 inches (11.2 millimeters long), but represents a new species, <i>Blanus mendezi</i>.

<p>Harvard recently announced a somewhat unsettling fact about one of the books in its library collection — it's bound in human skin.
</p><p>Houghton Library, the university's repository for rare books and manuscripts, confirmed Wednesday (June 4) that its copy of Arsène Houssaye's "Des destinées de l'ame" (Destinies of the Soul) is without a doubt swathed in the hide of a human being.</p><p>[Full Story: <a href="http://www.livescience.com/46152-harvard-book-bound-in-human-skin.htmll" target="_blank">Harvard Has a Book Bound in Human Skin...Your Move, Yale</a>]</p>
Puff puff puff
<p>Nicotine inhalers, which are devices similar to electronic cigarettes, have existed for years, but they were just not cool enough to catch on, researchers say.
</p><p>Listed among the treatments used for helping smokers quit, nicotine inhalers were approved by the Food and Drug Administration (FDA) in 1997. The devices deliver nicotine to the mouth when the smoker puffs at the plastic mouthpiece that looks like an old-fashioned cigarette holder.</p><p>[Full Story: <a href="http://www.livescience.com/46137-electronic-cigs-are-just-cooler.html" target="_blank">Smokers Say E-Cigs Are Just 'Cooler' than Other Inhalers</a>]</p>
