Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. Although both these tasks involve vision, the requirements of the visual system differ depending upon what the bee wants to achieve; locate a flower to feed from or adjust its
Popular Abstract in Swedish Jätteplaneterna, Jupiter, Saturnus, Uranus och Neptunus, är de största planeterna i solsystemet. De ligger långt från solen och har alla betydande gasatmosfärer, upp emot hundra gånger mer massiva än hela jorden. Tack vare de tjocka gashöljena, med en sammansättning som liknar solens, kan man förstå att jätteplaneterna bildades i en gasskiva. Denna skiva kallas för solGiant planets form embedded in a protoplanetary disc around a young star. Close to the midplane a large fraction of the available mass in solids is found in particles of cm to dm in size, which drift towards the star due to friction with the surrounding gas. In paper I, II, III we describe a novel theory that explains how embryos, planetesimals larger than ~1000 km, grow efficiently by sweeping up
Philosophers’ search for the best way to explain human actions has led many to accept a core psychological model that can be supplemented by other forms of action explanation when needed. Rather than settling for this model –where everything ultimately hinges on psychologicalexplanation – this paper argues for a pluralistic view. It does not claim that the psychological view is
Colorectal cancer (CRC) is the third most common cancer and the fourth leading cause of death from cancer worldwide. People suffering from inflammatory bowel disease, such as Crohns’ disease and ulcerative colitis, are at an increased risk of developing CRC. The development of CRC is highly influenced by the tumour microenvironment. Tumour cells are able to recruit macrophages and change their beh
