Could tainted cookware be poisoning an entire continent?


Despite the ban on lead in gasoline, blood lead levels in African nations have remained stubbornly high. Now, researchers think they might know why. Cookware made in Africa from recycled metals is leaching lead into food in quantities nearly 200 times the levels permissible in the United States...

Stunning photos of comet 67P at the end of Rosetta's decade-long journey


After a 10 year journey, the Rosetta spacecraft has rendezvoused with the comet 67P/Churyumov-Gerasimenko in the region of space between Mars and Jupiter. Rushing towards the inner solar system at around 30,000 miles per hour, the strangely shaped comet is presenting Rosetta's controllers with multiple challenges in establishing an orbit so that the spacecraft's instrument package can be deployed...

Flores' "hobbit" not a new human species, say detractors


Back in 2004, the excavation of unusual skeletal remains on the island of Flores, yielded what the discoverers claimed was "the most important find in human evolution for 100 years." But the so-called hobbit may not be a new human species at all, say the authors of a new paper, and may simply be the remains of an individual with Down syndrome...

Physicists map quantum to classical collapse


Extracting information from a system as it collapses from a quantum state to a classical state was never considered possible by the original founders of quantum theory, but Berkeley physicists have managed to extract information from a system continuously throughout its change of state, an achievement they say is like monitoring Schrodinger's cat through the whole life or death process...

Compelling new evidence for artificial lighting's role in breast cancer


Scientists have found that for laboratory rats with human breast tumors, exposure to dim light at night made the tumors resistant to the breast cancer drug tamoxifen. The new research is the first to show that a significant correlation exists between melatonin levels and the effectiveness of tamoxifen in treating breast cancer...

Prehistoric token "bookkeeping" persisted long into age of written language


An archaeological dig in Turkey has uncovered a large number of clay tokens that were used as records of trade before the advent of writing around 3,000 B.C. But the newly found tokens show the rudimentary accounting system didn't die out with the invention of writing, and persisted for at least another 2,000 years...

Algae turn quantum coherence on and off


A team of researchers has discovered how algae that survive in very low levels of light are able to switch on-and-off a quantum phenomenon known as coherence. The function of coherence in the algae remains a mystery, but the researchers think it could help the organisms harvest energy from the Sun much more efficiently. They add that working out its precise role in a living organism could lead to technological advances, such as much-improved organic solar cells...
