How 139 countries could be powered by 100 percent wind, water, and solar energy by 2050

Added: 23.08.2017 17:25 | 0 views | 0 comments

#zrodlo

The latest roadmap to a 100 percent renewable energy future outlines infrastructure changes that 139 countries can make to be entirely powered by wind, water, and sunlight by 2050 after electrification of all energy sectors. Such a transition could mean less worldwide energy consumption due to the efficiency of clean, renewable electricity; and a net increase of over 24 million long-term jobs.

Understanding Caribbean mammal extinctions of the past spurs renewed focus on conservation

Added: 23.08.2017 17:25 | 0 views | 0 comments

#zrodlo

Paleontologists report they have clear evidence that the arrival of humans and subsequent human activity throughout the islands of the Caribbean were likely the primary causes of the extinction of native mammal species there. The evidence, they say, highlights the need for urgent human intervention to protect the native mammal species still inhabiting the region.

#zrodlo

Astronomers have detected the first X-rays from a Type Ia supernova, located inside the spiral-shaped galaxy ESO 336-G009. Type Ia supernovae occur in binary star systems. One of the stars in the system must be a white dwarf star, the dense, carbon remains of a star that was about the size of our Sun. The [...]

Arsenic risk in Pakistan much greater than expected

Added: 23.08.2017 14:54 | 0 views | 0 comments

#zrodlo

Arsenic-contaminated groundwater may threaten the health of 50 to 60 million people in Pakistan. This is shown by a study in which data from 1,200 groundwater samples was analyzed and combined with hydrological parameters to generate a hazard map. This reveals for the first time the full extent of the risks to which the population of Pakistan is exposed. In addition, there is growing evidence that natural arsenic levels are increased by extensive irrigation.

#zrodlo

A powerful shockwave from the H.L. Hunley's own weapon killed the crew of the Confederate combat submarine as it sunk a Union ship. This finding comes from a four-year research project that involved repeatedly setting blasts near a scale model, shooting authentic weapons at historically accurate iron plate and many calculations on human respiration and the transmission of blast energy.

You and some 'cavemen' get a genetic checkup

#zrodlo

Evolution has weeded out genetic variants associated with diseases for millennia and propagated variants that protect against ailments, a comparative genetics study shows. But in the last 500 to 1,000 years that trend appears to have changed. Is the apparent reversal in genetic health underpinnings real? Or an odd coincidence in the early data set of this very new research field?

Physicists have described how observations of gravitational waves limit the possible explanations for the formation of black holes outside of our galaxy; either they are spinning more slowly than black holes in our own galaxy or they spin rapidly but are 'tumbled around' with spins randomly oriented to their orbit.

The last ice age transition to a warmer climate some 11,500 years ago did not include massive methane flux from marine sediments or the tundra, new research suggests. Instead, the likely source of rising levels of atmospheric methane was from tropical wetlands, authors of the new study say.
