Climate change: Water and green energy produced by a single device

Researchers have found a way to purify water and produce electricity from a single device powered by sunlight.

The scientists adapted a solar panel that not only generated power, but used some of the heat energy to distil and purify sea water, according to BBC.

They believe the idea could make a major difference in sunny climates with limited water supplies.

The lead author expects that a commercial device could be available in five years.

New Weapons Against Cancer: Millions of Bacteria Programmed to Kill

Genetically modified microbes release “nanobodies” that alert the immune system to cancer in mice, scientists report.

Scientists have used genetically reprogrammed bacteria to destroy tumors in mice. The innovative method one day may lead to cancer therapies that treat the disease more precisely, without the side effects of conventional drugs.

The researchers already are scrambling to develop a commercial treatment, but success in mice does not guarantee that this strategy will work in people.

“At some point in the future, we will use programmable bacteria for treatment,” said Doctors “we think there’s just too much potential.”

Cancer diagnosis: The need to boost the Raman technique

Researchers unite efforts to boost the application of the Raman technique in the Clinic

Although it is very advantageous for the early diagnosis of multiple pathologies, including cancer, perhaps because of ignorance, the Raman spectroscopy technique is still very little applied in the clinic. In Europe, only a few hospitals in the Netherlands, Germany and the UK use it.

Raman spectroscopy

Raman spectroscopy, identified with the name of the scientist who discovered it, the Indian Chandrasekhara Venkata Raman, Nobel Prize for Physics in 1930, is a high-resolution optical technique that through the incidence of radiation (light) on any sample can obtain information in seconds. That is, it provides information about the compounds present in the analyzed sample.

Physicists stuffed a ghostly 'skyrmion' full of 'antiskyrmions'

There are ghostly shapes hidden in magnetic fields.

They're not made of stuff in the way a lightning bolt or a beam of light is. A lighting bolt carries a fairly defined group of electrons from the sky all the way to the ground. Sunshine that hits your face consists mostly of the same photons that traveled millions of miles from the sun.

But magnetic fields contain things called skyrmions that are different from electrons and photons; a skyrmion is a knot of magnetic field lines looping around each other. As it drifts from one spot to the next,

Mars may have hosted life BEFORE Earth

Scientists have readjusted the timeline of the formative years on Mars and claim the red planet could have been home to life before Earth was habitable, according to Daily Mail.

A study has tweaked the timings of when the cratered surface stopped being bombarded with meteorites and says life may have developed between 4.2 billion and 3.5 billion years ago.

This, the authors claim, predates when Earth became a thriving oasis by around 500 million years.
