Un nuevo estudio sugiere que la participación en actividades de baja intensidad como el estar de pie puede no ser suficiente para compensar los riesgos de salud de estar sentado durante largos períodos de tiempo. Agregar a su rutina dos minutos de caminar cada hora, podría ser el truco. Estos hallazgos fueron publicados en la Revista Clínica de la Sociedad Americana de Nefrología (CJASN).

Numerosos estudios han demostrado que estar sentado durante largos períodos de tiempo cada día conduce a un mayor riesgo de muerte prematura, así como enfermedades del corazón, diabetes y otras enfermedades. Teniendo en cuenta que el 80 por ciento de los estadounidenses...

There’s diamond under them thar plants. A geologist has discovered a thorny, palmlike plant in Liberia that seems to grow only on top of kimberlite pipes—columns of volcanic rock hundreds of meters across that extend deep into Earth, left by ancient eruptions that exhumed diamonds from the mantle. If the plant is as choosy as it seems to be, diamond hunters in West Africa will have a simple, powerful way of finding diamond-rich deposits. Prospectors are going to “jump on it like crazy,” says Steven Shirey, a geologist specializing in diamond research at the Carnegie Institution for Science in Washington, D.C.

Electric car pioneer Tesla unveiled a "home battery" last week which its founder Elon Musk said would help change the "entire energy infrastructure of the world". Environmentally-conscious German customers are targeted as potential buyers of the product.

The Tesla Powerwall, unveiled on Thursday (30 April), can store power from solar panels, from the electricity grid at night when it is typically cheaper, and provide a secure backup in the case of a power outage.

In theory the device, which typically would fit on the wall of a garage or inside a house, could make solar-powered homes completely independent of the traditional energy grid.

The call by WWF Scotland follows the publication of new figures revealing that there was enough sunshine in April to have met more than 100% of the electricity needs of an average home in Scotland or 99% or more of an average household’s hot water needs.

Wind turbines in Scotland also generated enough electricity on average to supply the electrical needs of 69% of Scottish households - 1.66 million homes.

Last month, it was announced that work on Scotland’s largest solar park will start later this year in Angus.

The resilience of U.S. coastal communities to storms, flooding, erosion and other threats can be strengthened when they are protected by natural infrastructure such as marshes, reefs, and beaches, or with hybrid approaches, such as a “living shoreline” — a combination of natural habitat and built infrastructure, according to a new NOAA study.
