    [In Depth] Brazilian crisis threatens science and environment (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science

    Beschreibung: In the midst of Brazil's political turmoil, scientists and environmentalists are wondering whether they have an enemy in Interim President Michel Temer, who came to power after Dilma Rousseff was removed on 12 May. Days after Temer assumed office, the government merged the science ministry with the communications ministry, leaving researchers fearing for what's left of their already diminished budgets. Meanwhile, pro-development forces are moving ahead on a constitutional amendment that could speed approval for dams, highways, mines, and other megaprojects. The measure has alarmed scientists, environmentalists, and indigenous rights advocates, who fear it would gut the country's environmental licensing process. Author: Lizzie Wade

    Beschreibung: Recent dives into Colombia's Cartagena Bay have revealed an unusually resilient coral reef thriving in the polluted waters. But the reef faces a threat: an end to Colombia's decades-long guerrilla war. The government is on the verge of inking a peace deal with its main adversary, the Revolutionary Armed Forces of Colombia, or FARC. Experts expect peace to lead to a development boom, threatening ecosystems all over the country with deforestation and runoff. A new shipping lane is planned for Cartagena Bay, and construction will mean dredging right through the reef. Researchers believe studying the reef's resiliency could help struggling corals around the world and are racing to collect samples before it's too late. Author: Lizzie Wade

    [In Depth] Pyre experiments cast doubt on students' fate (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2016-09-16
    Beschreibung: In September 2014, 43 university students disappeared in Guerrero state in southern Mexico. The Mexican government has maintained that a drug cartel murdered the students and burned their bodies at a trash dump. New experiments using pig carcasses as a proxy for human bodies cast doubt on that theory of the crime. José Torero, a fire scientist at the University of Queensland, St. Lucia, in Brisbane, Australia, incinerated up to four pig carcasses at a time and determined that the inferno necessary to consume 43 bodies could not have occurred at the dump. His results suggest than Mexican investigators should look elsewhere to solve the mystery of the students' fate. Author: Lizzie Wade

    [Special Issue News] Clues from the ashes (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2016-03-11
    Beschreibung: The Mexican government's official story is that the bodies of 43 students who went missing in 2014 were burned at a dump outside the town of Cocula in the state of Guerrero. But José Torero, an internationally known fire investigator at the University of Queensland, St. Lucia, in Brisbane, Australia, says the evidence doesn't add up. Burning so many bodies completely would have required a massive amount of energy, he says. Torero is trying to bring more science to the field of fire investigations; many other analysts set out to prove an established theory of a crime, rather than ruling out hypotheses with the help of models and experiments, as Torero does, one his colleagues says.

    Beschreibung: Over the last 10 years, Mexico has invested heavily in training young scientists in genomics and sent many promising students abroad for Ph.D.s and postdocs. The new International Laboratory for Human Genome Research (LIIGH) in Juriquilla, Mexico, which celebrated its first anniversary this month, was built to bring home some of these rising stars. But returnees have been stymied by limited funding and a stifling bureaucracy, and many end up longing for the comparative ease of doing research in the United States and Europe. LIIGH is a testimony to Mexico's eagerness to build homegrown expertise in genomics—and to the challenges it faces to fully realize its potential. Author: Lizzie Wade

    [Feature] Unearthing democracy's roots (2017)
    American Association for the Advancement of Science (AAAS)

    Publikationsdatum: 2017-03-17
    Beschreibung: For decades, archaeologists thought democratic republics such as classical Athens and medieval Venice were a purely European phenomenon. Conventional wisdom held that in premodern, non-Western societies, despots simply extracted labor and wealth from their subjects. But archaeologists have identified several societies in pre-Columbian Mesoamerica that upend that model. They argue that societies such as Tlaxcallan in the central Mexican highlands and Tres Zapotes along the Mexican gulf coast were organized collectively, meaning that rulers shared power and commoners had a say in the government that presided over their lives. These societies were not necessarily full democracies in which citizens cast votes, but they were radically different from the autocratic, inherited rule found—or assumed—in most ancient societies. Archaeologists now say that these collective societies left telltale traces in their material culture and urban planning, such as repetitive architecture, an emphasis on public space over palaces, reliance on local production over exotic trade goods, and a narrowing of wealth gaps between elites and commoners.

    Beschreibung: For decades, Colombia's most interesting and diverse ecosystems have been occupied by guerrilla fighters and other armed groups, forcing scientists to stay away. But for a hopeful week, the threat finally seemed to have lifted. On 26 September, Colombia's government and the Revolutionary Armed Forces of Colombia signed an agreement ending 52 years of conflict. As the fighters pledged to lay down their weapons, scientists made plans to return to the field—sometimes to research stations they had been forced to abandon years earlier. But on 2 October, Colombians in a referendum narrowly rejected the peace accord, leaving researchers wondering when it will truly be safe for fieldwork, and whether Colombia will ever be able to direct its resources away from war and toward research.

    Beschreibung: More than 28,000 people have disappeared in Mexico since the beginning of the drug war in 2006. Some are kidnapped by drug cartels and either killed or forced into labor or human trafficking. Human rights groups say that many others are abducted by the police and military, and that the government does little to investigate. Faced with official inaction, the families of the disappeared have started searching on their own. In the eastern state of Veracruz, family members discovered the largest mass grave yet in Mexico; they have uncovered more than 100 bodies since August. Now, a team of forensic anthropologists is helping these families figure out how to seek justice for these crimes and pressure the authorities into improving their investigations. Author: Lizzie Wade

    [In Depth] Mexican scientists feel the Trump effect (2017)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2017-02-03
    Beschreibung: Two weeks into the presidency of Donald Trump, waves of angst are sweeping through the Mexican science community. The peso has plummeted against the dollar, affecting the value of grants: Mexican scientists purchase most of the research materials and equipment they use from the United States. Trump's insistence on building a border wall and making Mexico pay for it has made scientists nervous about the fate of funding and support for cross-border collaborations. In response to increasingly chilly relations, Mexico's National Council for Science and Technology said it will pursue collaborations beyond the United States, including with the European Union and China. Meanwhile, promising young Mexican scientists planning to go abroad are having second thoughts about studying in the United States, which no longer seems as welcoming as it once did.

    [In Depth] Neandertals made jewelry, proteins confirm (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2016-09-23
    Beschreibung: The "necklaces" are tiny: beads of animal teeth, shells, and ivory no more than a centimeter long. But they provoked an outsized debate that has raged for decades. Found in the Grotte du Renne cave at Arcy-sur-Cure in central France, they were reportedly found in the same layers as fossils from Neandertals. Some archaeologists credited the artifacts, described as part of the Châtelperronian culture, to our archaic cousins. But others argued that Neandertals were incapable of the kind of symbolic expression reflected in jewelry and insisted that modern humans must have been the creators. Now, a pioneering study uses ancient proteins to identify Neandertal bone fragments from Grotte du Renne for direct radiocarbon dating. The team finds that the link between the archaic humans and the artifacts is real. Author: Lizzie Wade
