An anonymous reader quotes a report from The Guardian: Early human ancestors came close to eradication in a severe evolutionary bottleneck between 800,000 and 900,000 years ago, according to scientists. A genomics analysis of more than 3,000 living people suggested that our ancestors’ total population plummeted to about 1,280 breeding individuals for about 117,000 years. […]
Slashdot reader sciencehabit writes: One thing most cats seem to have in common is a deep love of tuna. That’s an odd predilection for a creature that evolved in the desert, with nary a fish in sight. Now scientists think they’ve nailed down the biology behind this curious craving. In a series of experiments researchers […]
According to a team of researchers from RMIT University in Australia, coffee grounds can be used as a silica substitute in the concrete production process to yield a significantly stronger chemical bond than sand alone. Engadget reports: “The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gases including […]
Using data collected from the International Space Station (ISS), scientists found that a small yet growing percentage of tree leaves in tropical forests are approaching the maximum temperature threshold for leaves to photosynthesize,” reports Live Science. If this trend continues, it could spell disaster for Earth’s climate systems and biodiversity. The findings have been
An anonymous reader quotes a report from the New York Times: Scientists have trained a computer to analyze the brain activity of someone listening to music and, based only on those neuronal patterns, recreate the song. The research, published on Tuesday, produced a recognizable, if muffled version of Pink Floyd’s 1979 song, “Another Brick in […]

Comment on this storyComment A humble lake in a Canadian suburb may soon become the symbolic starting point for a radical new chapter in Earth’s official history: the Anthropocene, or the age of humans. A group of scientists said Tuesday the best evidence for humanity’s overwhelming impact on the planet could . . .
Nine days ago the U.S. government released a report on the advantages of studying “scientific and societal implications” of “solar radiation modification” (or SRM) to explore its possible “risks and benefits…as a component of climate policy.” The report’s executive summary seems to concede the technique would “negate (explicitly offset) all current or future impacts of […]
