Ancient serene galaxy suggests the early universe was eerily calm

×ByA strangely sedate galaxy in the early universe may upend our ideas about how galaxies form. We think most young galaxies in the early cosmos ought to be chaotic and turbulent, but galaxy SPT-SJ041839-4751.9, the earliest galaxy of its type we’ve been able to see with high resolution, isn’t.We see this galaxy as it was when the universe was just 1.4 billion years old and it is much too dim and distant to observe in detail using a regular telescope. Simona Vegetti at the Max Planck Institute for Astrophysics in Germany and her colleagues used a phenomenon called to take a picture of it...

African grey parrots are smart enough to help a bird in need

African grey parrots are smart enough to help a bird in need

×ByAfrican grey parrots are not only really smart, they are helpful too. They are the first bird species to pass a test that requires them both to understand when another animal needs help and to actually give assistance.Besides humans, only bonobos and orangutans have passed this test, says Désirée Brucks at the Ludwig Maximilian University of Munich in Germany. Even chimps and gorillas have failed at it.Brucks and first trained birds one at a time. Each was given a pile of tokens – small metal washers – and taught that they could exchange them for food by passing them to a researcher...

Changing how we make solar panels could reduce their carbon emissions

×ByChanging the way we make could reduce their carbon footprint, providing a boost to green energy.Although solar panels are a source of renewable energy, making them has an environmental impact. Fengqi You at Cornell University in New York and his colleagues have analysed the overall environmental impact of two types of new solar panels, comparing these against panels made with crystalline silicon wafers – the current industry standard.The team found that a new type of made from two layers of a mineral called perovskite requires a smaller total and results in fewer carbon emissions. The...

Colorado River drought can be predicted by warming in the ocean

×ByForecasting drought in the Colorado River, one of the most important rivers in the arid western US, could come down to ocean temperatures thousands of kilometers away.The Colorado River runs for around 2300 kilometres, providing water to vast farmlands and 30 million people in seven US states and Mexico.

Why old school technology could shape the future of digital computing

×ByAMID an epic haul of jewels and statues rescued from an ancient Greek shipwreck, it was a lump of corroded wood and bronze that would capture the world’s imagination. Pulled from the Mediterranean Sea in 1901, the was an astonishingly sophisticated 2000-year-old computer. The size of a shoebox, sporting chunky bronze gears rimmed with hundreds of triangular teeth, it was built to chart the paths of celestial bodies and was capable of addition, multiplication, subtraction and division – all by cranking a handle.Nearly half a century would pass before its significance became apparent.

We have seen hints of a new fundamental force of nature

We have seen hints of a new fundamental force of nature

×ByTASKED with telling the universe’s epic story, cosmologists have put on a compelling show. The curtain rises with a bang before a sweeping, unstoppable narrative unfolds. Stars form and explode, galaxies swirl their way into existence. munch and merge, sending out ripples through the auditorium.It is a ripping yarn – but the longer we watch it, the more it seems not quite to add up.
