Daily briefing: How to see quantum weirdness with our own eyes Daily briefing: How to see quantum weirdness with our own eyes, Published online: 29 April 2019; doi:10.1038/d41586-019-01391-4 The human visual system works surprisingly well as a quantum detector, gravitational ripples hint at black hole eating a star and 5G signals could trick weather satellites…

Engineers have flipped the picture of the standard polymer insulator, by fabricating thin polymer films that conduct heat — an ability normally associated with metals. In experiments, they found the films, which are thinner than plastic wrap, conduct heat better than many metals, including steel and ceramic. Press Release Distribution Service

A new study finds that veterans and active-duty service members with combat-related PTSD and mild traumatic brain injury had larger amygdalas — the region of the brain that processes such emotions as fear, anxiety, and aggression — than those with only brain injuries.

A rapidly changing jet orientation in the stellar-mass black-hole system V404 Cygni A rapidly changing jet orientation in the stellar-mass black-hole system V404 Cygni, Published online: 29 April 2019; doi:10.1038/s41586-019-1152-0 The relativistic jets associated with the black-hole X-ray binary system V404 Cygni change their orientation on time scales of minutes to hours, implying that the…

Reconfiguration of a bacterial transport system generates a reverse gear Reconfiguration of a bacterial transport system generates a reverse gear, Published online: 29 April 2019; doi:10.1038/d41586-019-01320-5 Some bacteria use multiprotein complexes to inject proteins into host cells. Components of these complexes have been linked to a nanotube-mediated route from host cells to bacteria that might…
