Homeless and Overweight: Obesity is the New Malnutrition

A new survey finds that one in three homeless people in Boston are clinically obese, a number that casts in relief the strange reality of food in the 21st century United States.

Not long ago, malnourishment was embodied by emaciation. Now it’s far more likely to be hidden in folds of fat.

“This study suggests that obesity may be the new malnutrition of the homeless in the United States,” wrote the researchers, led by Harvard Medical School student Katherine Koh, in an upcoming Journal of Urban Health study.

Space Cases: The Weirdest Legal Claims in Outer Space

In January, a Quebec man named Sylvio Langvein walked into a courthouse in Canada and filed a suit declaring himself owner of the planets in our solar system, four of Jupiter’s moons, and the interplanetary space between.

By way of explanation, Langvein said he wanted to collect planets the same way that others collect hockey cards, and also prevent China from establishing outposts above his head.

The judge overseeing the case, Alain Michaud, dismissed it in March, calling Langvein a “quarrelsome litigant” whose paranoid actions were an abuse of the Canadian legal system. (This was Langvein’s 45th lawsuit — including four motions to the Supreme Court of Canada — since 2001).

The case is bizarre, but not unprecedented.

“Every now and then, someone thinks no one has claimed the moon before, and then rushes to claim it,” wrote Virgiliu Pop, a space law researcher at the Romanian Space Agency, in an email to Wired. “Humankind has a short collective memory, so the claimant is able to create some buzz before the story dies out — to be followed by a similar story, years later.”

As we enter an era when people are seriously advocating that the U.S. establish property rights on the moon and scholars debate the legality of mining asteroids, it’s interesting (and relevant) to look back at the people who have tried to assert ownership of the moon, Mars, other planets, and stars throughout history.

In 2006, Pop literally wrote the book on this matter, titled Unreal Estate: The Men Who Sold The Moon, which he describes as “a serious analysis of a trivial subject.” The compendium offers plenty of outrageous stories, and here we look at some of the book’s most spurious and strange space cases.

Inherit the Moon

Alexander the Great is said to have wept when told by his friend, the philosopher Anaxarchus, that there are countless worlds in the universe.

“Do you not think it a matter worthy of lamentation that when there is such a vast multitude of worlds, we have not yet conquered one?” Alexander said.

Great as Alexander’s ambitions were, he never attempted to draw up documents declaring himself owner of anything in the sky. But one of the earliest modern cases where such claims are made comes from King Frederick the Great, who ruled Prussia in the mid-1700s.

The king was said to have sought help from a great healer named Aul Jurgens and, in exchange for the miraculous cures he received, bequeathed the moon to Jurgen’s family until the end of time. This story comes from one of Jurgen’s descendants, Martin, who in 1996 tried to claim lunar ownership through his illustrious ancestor.

The next year, scholars at the Institute for Air and Space Law in the Netherlands denied Jurgen’s claim on the grounds that the donation by a Prussian sovereign who didn’t actually own the moon in the first place wasn’t valid.

Up Close With Enceladus’ Magnificent and Strange Plumes

Saturn’s moon Enceladus is a strange place.

The cold, tiny moon in the far reaches of the solar system is an unlikely location for liquid water. Yet scientists have not only discovered that Enceladus contains water, it actually shoots magnificent plumes of it out into space.

These plumes and their origin remain a major mystery for researchers studying the moon and its environment. Where is the source of their liquid water and what causes them to fire out into space?

Here, Wired takes a closer look at the plumes in some of our favorite images of our favorite Saturnian moon.

Plasma Plumes

New evidence from the Cassini mission, currently in orbit around the ringed planet, suggests an unexpected property for the plumes: They are the source of a complex form of plasma around Saturn.

Plasma – a state of matter similar to a gas made partially of ionized particles – is the most common form of matter in the universe. Dusty plasmas, like those recently observed around Saturn, have small nano-sized particles suspended in them, producing completely different behavior from ordinary plasmas.

The water being ejected from Enceladus’ plumes is apparently forming this dusky plasma when it hits Saturn’s magnetic field. Researchers are eager to study the material since they rarely have an opportunity to see it up close in interplanetary space.

The results appear in two papers in this month's Journal of Geophysical Research Space Physics.

2 New Elements Named on Periodic Table

You can now greet by name two new residents of the period table of elements: Flerovium and Livermorium.

The International Union of Pure and Applied Chemistry officially approved names for the elements – which sit at slot 114 and 116, respectively — on May 31. They have until now gone by the temporary monikers ununquadium and ununhexium.

Both elements are man-made, having first been synthesized at the Joint Institute of Nuclear Research in Dubna, Russia, in 1998 and 2000.  The discoveries were confirmed with further work at Lawrence Livermore National Laboratory in California. Suggested names for the two elements have been pending since they were submitted to the IUPAC last year.

The elements were created by smashing calcium ions (with 20 protons) into curium targets (which have 96 protons), combining to form element 116, Livermorium. This element decayed almost immediately into Flerovium, with 114 protons.

In addition to providing new trivia for fifth-graders to memorize, the names honor the labs of their creation. Flerovium was chosen for Flerov Laboratory of Nuclear Reactions in Russia, a facility where many superheavy elements have been produced. The lab is named after physicist Georgiy N. Flerov, who discovered the spontaneous fission of uranium, which led to the USSR’s development of an atomic bomb.

Livermorium honors Lawrence Livermore National Laboratory in California, which has been involved in the discovery of heavy elements 113 through 118. Another element, Lawrencium at 103, is already named after the lab’s founder, Ernest O. Lawrence.

Chemistry geeks can take note that Flerovium’s symbol will be Fl (not to be confused with fluorine) and Livermorium’s will be Lv. The official names will be published in the July issue of the IUPAC journal, Pure and Applied Chemistry.

‘Schrödinger’s Hat’ Uses Invisibility to Measure Quantum World

Mathematicians now suspect quirks in energy-cloaking metamaterials could be exploited to create powerful quantum probes called “Schrödinger’s hats.”

Although not yet built or proven in the real world, such hats — their name a nod at Erwin Schrödinger’s famous cat-boxing thought experiment — might record extremely subtle signals that would otherwise be scrambled by any attempt to measure them.

Should the theoretical work pan out in the laboratory, Schrödinger’s hats could be a boon to nanotechnology, where the simple act of observing a nano-scale object can confound a measurement.

“Conceptually, a Schrödinger’s hat is like an invisible battery. It captures a tiny bit of energy without fiddling with the [energy] waves so you can later get a measurement,” said Allan Greenleaf, a mathematician at the University of Rochester. Greenleaf co-authored a study of the Schrödinger’s hats published May 29 in Proceedings of the National Academy of Sciences.

“If you’re trying to image something at the nanoscale, say a computer chip or nanodevice, you might get very close to it without disturbing it,” continued Greenleaf.
