# acad: oops! half of all EU trials are non-compliant

<< Of 7274 trials where results were due, 49.5% (95% confidence interval 48.4% to 50.7%) reported results. >>

<< Compliance with the European Commission requirement for all trials to post results on to the EUCTR [EU Clinical Trials Register] within 12 months of completion has been poor, with half of all trials non-compliant. >>

# brain: seeing "ghosted" images

<< the human eye and brain are together capable of seeing "ghosted" images >>

<< it is possible to create ghost images with a technique using light to make an image without reflecting it off the original object. The technique is called "ghosting," >>

<< Computational ghost imaging relies on the decomposition of an image into patterns that are summed together with weights that measure the overlap of each pattern with the scene being imaged. These tasks rely on a computer. Here [AA] demonstrate that the computational integration can be performed directly with the human eye. >>

# behav: a small fish (the cleaner wrasse L. dimidiatus) passes self-awareness test

AA << show that the cleaner wrasse fish, Labroides dimidiatus, passes through all phases of the mark test: (i) social reactions towards the reflection, (ii) repeated idiosyncratic behaviours towards the mirror (contingency testing), and (iii) frequent observation of their reflection. >>

<< Since the 1970s, a test developed by Gordon Gallup has been the gold standard for testing for self-awareness - researchers make a mark on a creature's face and introduce a mirror. If the animal makes some attempt to touch or remove the mark, they are deemed to have self-awareness. Since the test first came into use, only a few animals have ever passed the test. Besides humans, the list currently includes chimpanzees, bonobos, orangutans, dolphins, elephants and pigeons. >>

# gst: how to detect a sinkhole

<< It comes as quite a shock when the ground beneath your feet, your house or your field suddenly disappears leaving a hole. [..] We call these sinkholes, and they are a global problem. >>

<< These voids may eventually come to the surface over time as the roof progressively collapses. These collapses can be gradual, or can happen suddenly, with surface depressions appearing overnight without warning. >>

<< Walking is one of the things that distinguishes us from all other animals and, according to a Harvard Medical School Review, "walking doesn't get the respect it deserves". >>

# gst: even repulsive interactions generate solitons

<< Solitons are nonspreading wave packets that exist in a wide range of real-world systems, including water waves, sound, DNA, optics, and so on. >>

<< Two or more solitons can bind together to form a soliton molecule with dynamics similar to matter molecules, such as vibration, synthesis, and dissociation. >>

<< Formation processes for three types of soliton molecules were studied: ground-, excited-state, and a new one termed an intermittent-vibration soliton molecule. While it is generally believed that attractive interactions of solitons are responsible for the formation of soliton molecules, the authors found that soliton interactions are not limited to attractive interactions. Counterintuitively, even repulsive interactions can lead to the formation of soliton molecules, >>

<< For closely‐separated bound solitons, soliton interactions display wide diversities in repeated measurements, including soliton attraction, repelling, collision, vibration, and annihilation. For well‐separated bound solitons, repulsive interactions dominate the soliton interactions. >>
