black-hole-eating star
Supermassive black-hole-eating star ejects high-speed flare December 1, 2015 [image: Artist’s conception of a star being drawn toward a black hole and destroyed (left), and the black hole later emitting a “jet” of plasma composed of the debris left from the star’s destruction. (credit: modified from an original image by Amadeo Bachar.)] An international team of astrophysicists has for the first time witnessed a black hole swallowing a star and ejecting a flare of matter moving at nearly the speed of light. The finding, reported in the journal Science, tracks the star — about the size... mais »

long-term memories
Possible biochemical mechanism underlying long-term memories identified December 4, 2015 [image: Neuronal synapse-ft] Why is a prion-like molecular state necessary for persistence of memory? Could a transient memory be made permanent with a "Limitless" NZT-type neurotropic drug --- or permanently forgotten? It’s a nagging question: why do some of our memories fade away, while others last forever? Now scientists at the Stowers Institute for Medical Research have identified a possible biochemical mechanism: a specific synaptic protein called Orb2 can either block or maintain neural synap... mais »

On Learning
5 classic studies of learning [image: Photo by Wellcome and Flickr user Rebecca-Lee. Click for source.]I have a piece in the Guardian, ‘The science of learning: five classic studies‘. Here’s the intro: A few classic studies help to define the way we think about the science of learning. A classic study isn’t classic just because it uncovered a new fact, but because it neatly demonstrates a profound truth about how we learn – often at the same time showing up our unjustified assumptions about how our minds work. My picks for five classics of learning were: - Bartlett’s “War of the... mais »

Tempestades solares
*Tempestades solares* [image: 1397170799384530245] Todos sabemos que tempestades podem causar inundações e danos à infraestruturas. Mas existe um perigo muito maior do que a chuva ou o vento: as intempéries espaciais. Se o planeta fosse atingido por uma tempestade solar gigantesca, nossa tecnologia seria completamente destruída e o planeta mergulharia na escuridão. “Dependemos da tecnologia, que por sua vez é vulnerável ao clima espacial”, disse Thomas Berger, diretor do Centro de Previsão do Clima Espacial da Administração Atmosférica e Oceânica Nacional (ou NOAA, sigla para National... mais »
