Children to get CRISPR treatment for sickle cell disease in trial
×Bygene-editing trials for treating sickle cell disease and beta thalassaemia are being extended to include children aged under 12 after the therapies proved successful in ongoing trials involving people aged between 12 and 35. The aim is to treat children early enough to prevent them getting lasting damage from these .“The results are superb,” says at Imperial College London, a doctor who is involved in the trials, which include patients from multiple sites across the European Union, UK and US.Now, the challenge will be making the treatment widely available, which could be an issue because...…×Bygene-editing trials for treating sickle cell disease and beta thalassaemia are being extended to include children aged under 12 after the therapies proved successful in ongoing trials involving people aged between 12 and 35.

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.

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.

Birds and other animals may see colours that we cannot even imagine

Such colours are called spectral colours because they are part of the visible spectrum, ranging from red and yellow to blue and violet.The exception is , which can be evoked only by a combination of red and blue light, not by any single wavelength.

For a month at a time, he and his colleagues would watch a giant balloon carrying a collection of antennas float high above the ice, scanning over a million square kilometres of the frozen landscape for evidence of high-energy particles arriving from space.When the experiment returned to the ground after its first flight, it had nothing to show for itself, bar the odd flash of background noise.
