In science news around the world, a new strain of bird flu hits South Korea, the first fish is ready to be removed from the endangered species list, CERN plans a new 100-kilometer-long circular successor to the Large Hadron Collider, and more.

Forensic chemist Mario Thevis tells Science about a dangerous new performance drug that could be in play at the Winter Olympics in Sochi.

University College London staff and students create busts of Charles Darwin from unconventional materials to celebrate the famed scientist's 205th birthday.

Researchers sequenced the complete nuclear genome of an infant found on land owned by the Anzick family back in 1968. The so-called Anzick child, represented by a skull and a few other bones, was closely associated with sophisticated tools from the Clovis culture, thought to be the first well-established presence of the earliest Americans. The genome is especially closely related to that of today's native populations from Central and South America, establishing a direct link between ancient Paleoindians and Native Americans.

An emerging global network of detectors is watching for gravitational waves: ripples in spacetime predicted by Albert Einstein's general theory of relativity. As part of an ongoing upgrade of the Laser Interferometer Gravitational-Wave Observatory, scientists want to extend the global network. India has offered to host a detector that could come online in 2020; the Indian government must still develop a management structure for the project and commit to a schedule and budget.

Policy wonks can gorge on the 2014 edition of the biennial Science and Engineering Indicators from the National Science Foundation. The 600-page tome tracks the continued rise of China and other Asian countries at the same time it documents areas where the United States has retained its preeminence.

The science doesn't support a claim that gray wolves (Canis lupus) didn't live in the eastern United States before they were hunted nearly to extinction almost a century ago, a four-member independent panel review concluded in a report released 7 February. The U.S. Fish and Wildlife Service has argued that a different species of eastern wolf historically lived in 22 eastern states. If true, that scenario would support the agency's proposal to remove gray wolves from the endangered species list, because western populations have recently rebounded and the agency would have no legal obligation to restore the wolf to its eastern habitat, because it never lived there. But the panel, while not disputing the possible existence of an eastern species, rejected the idea that the two types of wolves did not live side by side in the East.

Marthe Gautier, an 88-year-old French pediatric cardiologist, claims she hasn't received proper credit for her role in the discovery of the cause of Down syndrome in the late 1950s. Gautier says she was the first to notice that patients carried an extra chromosome in their cells. But her colleague Jérôme Lejeune was the first author on a paper about the discovery, which was prepared without Gautier's involvement. The conflict came to a head on 31 January in Bordeaux, when an award ceremony for Gautier was called off at the last minute after the Jérôme Lejeune Foundation sent two bailiffs to record Gautier's speech.

The National Ignition Facility (NIF), a troubled laser fusion lab in California, has finally produced some results fusion scientists can get enthusiastic about. In a series of experiments last year, NIF researchers produced yields of energy 10 times greater than achieved before and demonstrated the phenomenon of self-heating that will be crucial if fusion is to reach its ultimate goal of "ignition"—a self-sustaining reaction that produces more energy than it consumes.

If electrons are the lifeblood of a modern economy, copper makes up its blood vessels. In cables, wires, and contacts, copper is at the core of the electrical distribution system, from power stations to delicate electronics. As consumption has risen exponentially—reaching 17 million metric tons in 2012—miners have met the world's demand for 10,000 years. But that might soon change. A group of resource specialists has taken the first shot at projecting how much more copper miners will wring from the planet. Results of their model, described this month, show that production peaks by about midcentury even if copper is more abundant than most geologists believe. That would drive prices sky-high, trigger increased recycling, and force inferior substitutes for copper on the marketplace.

Most mammalian cells carry two sets of chromosomes, but a few types of cells—including the mainstays of the liver and heart—have additional chromosome sets, a condition known as polyploidy. The advantage of polyploidy for mammalian cells has been unclear. But by tinkering with cells' chromosome endowments, researchers are testing polyploidy's possible advantages. Polyploidy might aid some cells by boosting their size. And in the liver, polyploidy might spur regeneration by creating genetic diversity among cells. Researchers are also working to test whether inducing polyploidy in certain cells can combat a deadly type of leukemia.
