New laws mean MDs must keep up to date on living-will and related legislation.

Lawyer Karen Capen discusses the legal aspects of documents such as living wills, advance directives and "proxies for personal care." Most provinces are enacting legislation to govern such directives, and physicians should keep abreast of new legislation and regulations in their jurisdiction.     

A warning to MDs: If you want to keep calls confidential,hang up the cordless phone

Medical professionals who use cordless telephones in the home or office may jeopardize both patient confidentiality and their personal privacy. A lengthy investigation revealed that many doctors are unaware that anyone with a radio-frequency scanner or tuneable very-high-frequency receiver can eavesdrop on conversations with patients, colleagues and business and financial advisers — anyone they talk to on a cordless phone.     

Reduced carbon emissions and fishing pressure are both necessary for equatorial coral reefs to keep up with rising seas

A rapid increase in sea-level rise is generating vertical accommodation space on modern coral reefs. Yet increases in sea-surface temperatures (SSTs) are reducing the capacity of coral reefs to keep up with sea-level rise. We use ensemble species distribution models of four coral species (Porites rus, Porites lobata, Acropora hyacinthus and Acropora digitifera) to gauge potential geographic differences in gross carbonate production. Net carbonate production was estimated by considering erosional rates of ocean acidification, increasing cyclone intensity, local pollution, fishing pressure and the projected burdens of increases in SSTs (under Representative Concentration Pathways (RCPs) 4.5, 6.0 and 8.5) through to the year 2100. Our models predict that only 4 ± 0.1% (~60 000 km²) of Indo-Pacific coral reefs are projected to keep up with sea-level rise by the year 2100 under RCP 8.5 – most of which will be located near the Equator. However, with drastic reductions in emissions (under RCPs 4.5 and 6.0 Wm⁻²), we predict that 15 ± 0.3% (~250 000 km²) (under RCP 4.5 Wm⁻²) and 12 ± 0.7% (~200 000 km²) (under RCP 6.0 Wm⁻²) of Indo-Pacific coral reefs, have the potential to keep up with sea-level rise by the year 2100. Yet the burdens of fishing pressure and its cascading effects are projected to be responsible for substantial reef erosion, nearly halving the number of reefs able to keep up with sea-level rise. If action is taken immediately and emissions are drastically reduced to RCPs 4.5 or 6.0 Wm⁻², and reef management reduces the burdens of local pollution and fishing pressure, then our model predicts that 21–27% (~350 000–470 000 km²) of Indo-Pacific coral reefs – most of which will be located near the Equator – would have the potential to keep up with sea-level rise by the year 2100.     

The Human Frontier Science Program: its aims and a proposal for its implementation

Reactions to the Human Frontier Science Program have been mixed. It has been welcomed as an important initiative in basic biological research yet regarded with suspicion by some outside Japan who see it as facilitating access to European and North American fundamental research. However, suspicion is clearing away and the governments concerned are looking forward to the Program's implementation. In this article, the Program's aims and the mechanisms for its execution are outlined as proposed in the light of a recent feasibility study.
