Baby Neanderthal breast-fed for 7 months
<p> A baby Neanderthal who lived in what is now Belgium about 100,000 years ago started eating solid food at 7 months old, revealing a new aspect of the evolution of breast-feeding.</p>
<p> The precision of this estimate is courtesy a new technique that uses elements in teeth to determine when breast-feeding started and stopped. Though researchers can't be sure the young Neanderthal's pattern was typical of its kind, such a breast-feeding pattern is not unlike that seen in many modern humans.</p>

Quakes cause GPS errors
<p> Thirteen years of supersized earthquakes, such as today's (May 24) magnitude-8.3 in Russia, have contaminated GPS sites around the world, a new study finds.</p>
<p> The Global Positioning System is a network of satellites and ground stations that provide location information anywhere on Earth. Except for spots in Australia, western Europe and the eastern tip of Canada, every GPS site on the ground underwent small but important shifts since 2000 because of big earthquakes, according to a study published May 6 in the Journal of Geophysical Research: Solid Earth.

Cockroaches evolved to avoid sugary baits
<p> In the ongoing battle between humans and cockroaches, the insects have a leg up. A new study finds that roaches evolved their taste buds to make sweet insecticide baits taste bitter. As a result, the roaches avoid the baits and thrive, to the frustration of homeowners everywhere.</p>
<p> Plenty of insects evolve resistance to pesticides; they gain the ability to break down poisons without dying. German cockroaches, on the other hand, evolved what's known as a behavioral resistance to baits. They simply stopped eating them.

Baby saved with 3D printing
<p> When April and Bryan Gionfriddo brought home their newborn son, Kaiba, in October 2011, he seemed like a healthy baby. But one night, when the family was out to dinner, Kaiba stopped being able to breathe and turned blue. Bryan laid Kaiba, just 6 weeks old, on the restaurant table and performed chest compressions on him before he was rushed to the hospital.</p>
<p> After 10 days, Kaiba was sent home, but he turned blue again two days later. That's when doctors realized Kaiba had a rare condition called tracheobronchomalacia, in which the windpipe is so weak that it collapses, preventing air from flowing to the lungs.

A drug that prevents brain aging?
<p> Sharply reducing calorie intake, by as much as 40 percent, could slow aging in cells and may even prolong life span, studies have suggested. Now, researchers say they have found a way to mimic the beneficial effects of calorie restriction on the brain with a drug.</p>
<p> The pill activates an enzyme in brain cells, and the study showed the drug delayed both the cognitive impairment associated with aging and Alzheimer's disease, and the loss of nerve cells that happens with aging.

Why penguins quit flying
<p> Humans spent centuries conspiring to fly, so it might be hard to imagine that any creature would give up the skill, and yet penguins waddle among us. A new study helps confirm that these seabirds traded flight to become better swimmers.</p>
<p> Penguins have a litany of physical features that make them energy-efficient underwater. For instance, their shortened wingspans lessen drag; their dense wing bones make them less buoyant; and their bulky bodies help them stay insulated and dive deeper. Unlike other aquatic birds that paddle underwater with their webbed feet, penguins beat their wings to propel themselves far below the surface. Emperor penguins can even go to depths greater than 1,500 feet (450 meters), lasting 20 minutes on a single breath.

Crazy ants driving out fire ants
<p> Invasive fire ants have been a thorn in the sides of Southerners for years. But another invasive species, the so-called "crazy" ant — that many describe as being worse — has arrived and is displacing fire ants in several places.</p>
<p> "When you talk to folks who live in the invaded areas, they tell you they want their fire ants back," said Edward LeBrun, a researcher at the University of Texas at Austin, in a statement from the school. "Fire ants are in many ways very polite. They live in your yard. They form mounds and stay there, and they only interact with you if you step on their mound."

Has famous math problem been solved?
<p> Infinity down, only 69,999,997 to go.</p>
<p> New research has proven that prime numbers don't just disappear as numbers get larger — instead, there is an infinite number of prime numbers separated by a distance of at most 70 million.

Dolphin finds rare torpedo
<p> A Navy dolphin training to look for mines off the coast of San Diego found a museum-worthy 19th-century torpedo on the seafloor, military officials said.</p>
<p> The brass-coated, retro wonder of technology was one of the first self-propelled torpedoes used by the U.S. Navy. Just 50 of these so-called Howell torpedoes were made and only one other example has been recovered; it sits in the Naval Undersea Museum in Keyport, Wash., outside of Seattle.

Stephen Hawking gets superhero treatment
<p> Living legend Stephen Hawking has already achieved superhero status in the eyes of many science geeks, and now his ideas are being honored in comic book form.</p>
<p> "Stephen Hawking: Riddles of Time & Space" (Bluewater) details the life story of the physicist, from his early days at Cambridge and struggles with a body-wrecking disease to his academic achievements and current fame.
