As observed in the unique orbits of cosmic dust particles, at small length scales, environmental forces such as solar pressure and the Loretz force can compete with gravity so significantly accelerate a body in space.

Betterinformed patients, they say, are more likely to take better care of themselves.

Water: Unclogging the finance

    How to improve water systems is one challenge; financing them is another. Public authorities in most countries play the main role in implementing and funding water infrastructure, but it is a model that is under increasing pressure, with government budgets and banks still prudent about issuing credit.    

     There is no generic funding model that can be applied to every need; the sheer diversity of water infrastructures and sources of financing to be identified, scanned and tapped in line with particular investment types and needs.

     There may be small-scale projects initiated by local entrepreneurs, or large infrastructures that serve multiple, such as energy and heavy manufacturing. Some investments may involve green ecosystems to supply, store or filter water.

     Not only will these infrastructures have different financing needs, but will access funds in different ways, for instance through capital markets, loans, funds, public expenditures, etc.

     Take large dams and large reservoirs. These are costly, long-term affairs. The Three Gorges Dam project in China, for instance, could cost over US$22 billion, according to government, including construction, relocation of residents and financing costs.

     Moreover, cost recovery is not expected to occur for 10 years after full operation starts. Such major projects tend to be financed major development banks such as the Asian Development Bank and World Bank, and institutional investors such as pension funds. The sources for long-term financing are expanding, with the emergence of sovereign funds and philanthropists,  of new groups like the Chinese-led Asian Infrastructure Investment Bank,  opened in March 2015.

Since visiting the injured military men and women at Headley Court, Mr Simpson established the On Course Foundation, a military charity that supports the recovery of wounded, injured and sick service personal through golf tuition and jobs in the golf industry.

One of the challenges in lab safety is that the lab setting becomes very familiar to people who work in it day in and day out. “When you do something over and over, your perception of the risk may change even though the risk itself doesn’t change,” says Lawrence M. Gibbs, associate vice provost for EH&S at Stanford. His department tries to use information about incidents to remember researchers not to get too comfortable. In that way, hopefully something positive can come out of Sangji’s death. “It was a tragic, tragic incident,” Gibbs says. “We all have to learn from it and use it as reinforcement to help people understand the potential risks of working with high-hazard materials in this environment.
