Why elephants rarely get cancer is a mystery that has stumped scientists for decades. A study led by researchers at Huntsman Cancer Institute (HCI) at the University of Utah and Arizona State University, and including researchers from the Ringling Bros. Center for Elephant Conservation, may have found the answer.

Deep in the jungles of the Yucatan peninsula, residents of the remote Mexican village of La Mancalona are producing clean drinking water using the power of the sun.

For nearly two years now, members of the community, most of whom are subsistence farmers, have operated and maintained a solar-powered water purification system engineered by researchers at MIT.

The system consists of two solar panels that convert sunlight into electricity; these, in turn, power a set of pumps that push water through semiporous membranes in a filtration process called reverse osmosis. The setup purifies both brackish well water and collected rainwater, producing about 1,000 liters of purified water a day for the 450 residents.

Un pre-histórico colapso repentino de uno de los volcanes oceánicos más altos y más activos en la Tierra, el Fogo en las islas de Cabo Verde, provocó un mega-tsunami con olas que impactaron a 220 metros (721 pies) sobre el nivel del mar actual, dando lugar a consecuencias catastróficas, según un nuevo estudio de la Universidad de Bristol publicado en la revista Avances de la Ciencia (Science Advances)

El estudio, dirigido por el Dr. Ricardo Ramalho de la Facultad de Ciencias de la Tierra de Bristol, ofrece nueva evidencia de la Isla Santiago, la más grande del archipiélago de Cabo Verde, para confirmar un largo debate de que los colapsos laterales de la isla volcánica pueden ocurrir catastróficamente y desencadenar tsunamis gigantes.

A new University of Washington study that tested 65 wines from America’s top four wine-producing states — California, Washington, New York and Oregon — found all but one have arsenic levels that exceed what’s allowed in drinking water.

The U.S. Environmental Protection Agency allows drinking water to contain no more than 10 parts per billion of arsenic. The wine samples ranged from 10 to 76 parts per billion, with an average of 24 parts per billion.

When you think of Chernobyl you probably think along the lines of “nuclear disaster” and a “no-go” area, but new research shows that with humans now absent from the region, several mammal species including wild boar and wolves, are increasing in number in this most unlikely nature reserve.
