An ultra-short-period super-Earth with an extremely high density and an outer companion.

We present the discovery and characterization of a new multi-planetary system around the Sun-like star K2-360 (EPIC 201595106). K2-360 was first identified in K2 photometry as the host of an ultra-short-period (USP) planet candidate with a period of 0.88 d.

GJ 367b: A dense, ultrashort-period sub-Earth planet transiting a nearby red dwarf star.

Ultrashort-period (USP) exoplanets have orbital periods shorter than 1 day. Precise masses and radii of USP exoplanets could provide constraints on their unknown formation and evolution processes. We report the detection and characterization of the USP planet GJ 367b using high-precision photometry and radial velocity observations.

A nearby transiting rocky exoplanet that is suitable for atmospheric investigation.

Spectroscopy of transiting exoplanets can be used to investigate their atmospheric properties and habitability. Combining radial velocity (RV) and transit data provides additional information on exoplanet physical properties. We detect a transiting rocky planet with an orbital period of 1.

An absolute sodium abundance for a cloud-free 'hot Saturn' exoplanet.

Broad absorption signatures from alkali metals, such as the sodium (Na I) and potassium (K I) resonance doublets, have long been predicted in the optical atmospheric spectra of cloud-free irradiated gas giant exoplanets. However, observations have revealed only the narrow cores of these features rather than the full pressure-broadened profiles. Cloud and haze opacity at the day-night planetary terminator are considered to be responsible for obscuring the absorption-line wings, which hinders constraints on absolute atmospheric abundances.

Helium in the eroding atmosphere of an exoplanet.

Helium is the second-most abundant element in the Universe after hydrogen and is one of the main constituents of gas-giant planets in our Solar System. Early theoretical models predicted helium to be among the most readily detectable species in the atmospheres of exoplanets, especially in extended and escaping atmospheres . Searches for helium, however, have hitherto been unsuccessful .

Improving multidisciplinary communication at ward board rounds using video enhanced reflective practice.

The priority to ensure patient safety and use resources effectively, demands attention and innovation. Video enhanced reflective practice (VERP) provides training based upon analysis of film clips of one's professional practice to develop practical insight into the processes of communication, so that effective changes can be made to ongoing behaviour and practice. In this case the focus was on multi-disciplinary communication within daily board rounds on an acute medicine and care of the elderly ward.

Osteological pathology in a Humpback (Megaptera novaeangliae) and Fin (Balaenoptera physalus) whale skeleton.

The Natural History Collections, Bergen Museum, The University of Bergen, Norway, houses a large collection of Baleen whale skeletons within which one mature Fin (Balaenoptera physalus) and one juvenile Humpback (Megaptera novaeangliae) whale skeleton exhibit notable osteological pathologies that are reported in this brief communication. The Humpback skeleton has a large lesion on the maxilla characterised by loss of bone and remodelling. The lesion would appear to be a healing injury caused by trauma to the area of the gums and adjacent soft tissue.

A high C/O ratio and weak thermal inversion in the atmosphere of exoplanet WASP-12b.

The carbon-to-oxygen ratio (C/O) in a planet provides critical information about its primordial origins and subsequent evolution. A primordial C/O greater than 0.8 causes a carbide-dominated interior, as opposed to the silicate-dominated composition found on Earth; the atmosphere can also differ from those in the Solar System.

An orbital period of 0.94 days for the hot-Jupiter planet WASP-18b.

The 'hot Jupiters' that abound in lists of known extrasolar planets are thought to have formed far from their host stars, but migrate inwards through interactions with the proto-planetary disk from which they were born, or by an alternative mechanism such as planet-planet scattering. The hot Jupiters closest to their parent stars, at orbital distances of only approximately 0.02 astronomical units, have strong tidal interactions, and systems such as OGLE-TR-56 have been suggested as tests of tidal dissipation theory.

Cause of death in judicial hanging: a review and case study.

The cause of death in judicial hanging is controversial and often attributed to 'hangman's fracture' of the second cervical vertebra. Research has shown that such fractures are the exception in judicial hangings and the cause of death can be attributed to a range of head and neck injuries, particularly compression or rupture of the vertebral and carotid arteries leading to cerebral ischaemia. The rapidity of loss of consciousness and death is highly dependent upon knot positioning and the length of drop which has varied through the history of hanging as a capital punishment in the UK.

Emergency anaesthesia in a patient with Gordon's syndrome.

Gordon's syndrome is a rare condition characterized by hypertension and hyperkalemia despite normal renal glomerular function. We report the administration of an anaesthetic to one such patient for an urgent surgical procedure. The patient's serum potassium was only marginally raised at the outset of the procedure.

A 5-microm filter does not reduce propofol-induced pain.

We assessed the effectiveness of a 5-microm filter in reducing propofol-induced pain and determined whether any reduction is due to removal of contaminants or an alteration in flow characteristics. A total of 120 unpremedicated women (ASA 1-3, aged 18-70 yr) were randomly allocated to one of three equal-sized groups. In group A, propofol was drawn up and injected through an unfiltered plastic cannula.

X-ray observations of accreting white-dwarf systems.

Accretion in white-dwarf binary systems can occur through discs, accretion columns or a combination of these, depending on the magnetic field of the white dwarf. Recent high-quality X-ray observations with the XMM-Newton and Chandra observatories have significantly advanced our understanding of the physics of the accretion process, and place severe tests on our existing models. There have been some surprises, such as the strong dependence of atmospheric heating on accretion rate.
