Space launches make kids sick

Hydrazine fingered in leaked study


Children living close to the old Soviet Union's oldest space launch pad are more likely to suffer hormonal problems and blood disorders, according to a Siberian study leaked to the journal Nature.

The study claims that the rates of such diseases have doubled in some cases in populations near the Baikonur Cosmodrome in Kazakhstan. However, the research has not been published, and was rejected by Russia's space agency. A spokesman for the agency said it kept a close eye on pollution levels, and was not aware of any health problems. He added that areas that were polluted were compensated.

The Baikonur Cosmodrome saw the launch of the rocket that carried Yuri Gagarin to space, and is the oldest space launch pad in the world. It is also where flights leave for the International Space Station. The Russian Space Agency leases the facility from Kazakhstan.

Researchers studied the medical records of 1,000 children in areas close to the launch pad. It found that children in areas most affected were twice as likely to need medical treatment as those in unpolluted areas. The authors conclude that waste hydrazine fuel, left unburned from early stages of launches, is responsible for the high rate of illnesses.

Fabio Caramelli, an engineer at the European Space Research and Technology Centre, said the fuel was "nasty and toxic", BBC Online reports. "A tablespoon of hydrazine in a swimming pool would kill anyone who drank the water," he said.

The ESA uses the Baikonur facilities, but a spokesman for the agency said the pollution "is a matter for the Russian space agency,". ®

  • DRAM, it stacks up: SK hynix rolls out 819GB/s HBM3 tech

    Kit using the chips to appear next year at the earliest

    Korean DRAM fabber SK hynix has developed an HBM3 DRAM chip operating at 819GB/sec.

    HBM3 (High Bandwidth Memory 3) is a third generation of the HBM architecture which stacks DRAM chips one above another, connects them by vertical current-carrying holes called Through Silicon Vias (TSVs) to a base interposer board, via connecting micro-bumps, upon which is fastened a processor that accesses the data in the DRAM chip faster than it would through the traditional CPU socket interface.

    Seon-yong Cha, SK hynix's senior vice president for DRAM development, said: "Since its launch of the world's first HBM DRAM, SK hynix has succeeded in developing the industry's first HBM3 after leading the HBM2E market. We will continue our efforts to solidify our leadership in the premium memory market."

    DARPA imitator not doing much after two years of Johnson government

    Updated The UK's efforts to copy US government and military innovation outfit DARPA are stalling, according to a leading figure in research and development.

    Appearing before the Science and Technology Committee, Sir John Kingman, former chair of UK Research and Innovation, told MPs this morning that ARIA – the Advanced Research and Invention Agency – was a good example of departmental research spending that could be cut, sidelined or delayed.

    "A very high-profile example would be ARIA, which has been this big plan for the Boris Johnson government, and yet here we are a few years into the Johnson government and it still hasn't even begun to happen," he told MPs.
