Solar Cell Absorbs High-Energy Light at 30-fold Higher Concentration than Conventional Cells

Bathing the Earth with enough energy in one hour to meet human needs for an entire year, the sun represents the ultimate source of clean, green sustainable energy. That being said, a team of scientists have created solar cells that collect higher energy photons at 30 times the concentration of conventional solar cells, the highest luminescent concentration factor ever recorded.

This giant floating solar farm concept in Barcelona could produce almost 10 tonnes of food each year

The world population is predicted to grow from 6.9 billion in 2010 to 8.3 billion in 2030 and to 9.1 billion in 2050. By 2030, food demand is predicted to increase by 50% (70% by 2050). The main challenge facing the agricultural sector is not so much growing 70% more food in 40 years, but making 70% more food available on the plate.

Gigantic Sinkhole Opens Up in Manchester

Another giant sinkhole, 3 meters (10 feet) deep and 1.5 meters (5 feet) wide has appeared in Manchester, just weeks after another crater opened in the middle of a road.

Three Category 4 hurricanes have just hit the Pacific Ocean at the same time - ScienceAlert

For the first time in recorded history, three Category 4 hurricanes have appeared in the Pacific Ocean at the same time, and they’re inching ever-closer to the Big Island of Hawaii. The never-before-seen meteorological event involves the hurricanes Kilo, Ignacio, and Jimena, the latter of which has sustained winds of up to 225 km/h. 

NASA scientists warn of accelerating sea level rise as ice sheets melt

As the world's ice sheets melt in response to warming air and ocean temperatures, global sea level is increasing. This is already putting cities from New York to Shanghai at risk of almost routine flooding from even relatively minor storms.

NASA Contest Offers $25,000 for Earthquake Detection Ideas

The space agency calls its challenge the "Quest for Quakes," and seeks to inspire new software codes and algorithms to identify electromagnetic pulses (EMP) that scientists theorize precede an earthquake.
Scientists have debated the connection between electromagnetic pulses and earthquakes for years, some believing distinct ultra-low frequency EMPs that emanate from the ground near earthquake epicenters for weeks prior to moderate and large quakes can be measured and used to warn people before an earthquake happens.

Study finds price of wind energy in US at an all-time low, averaging under 2.5 cent/kWh

Wind energy pricing is at an all-time low, according to a new report released by the U.S. Department of Energy and prepared by Lawrence Berkeley National Laboratory (Berkeley Lab). The prices offered by wind projects to utility purchasers averaged under 2.5¢/kWh for projects negotiating contracts in 2014, spurring demand for wind energy.

Alarming new report warns coastal cities may be uninhabitable within 50 years - ScienceAlert

A new report by former NASA scientist James Hansen and 16 other experts says the already dire projections on rising sea levels are actually too optimistic, having underestimated the rate at which Earth’s ice sheets will melt in response to warmer sea temperatures.

The researchers suggest glaciers in Greenland and Antarctica may melt as much as 10 times faster than what has previously been indicated by scientific modelling, which will result in drastic sea level rises occurring far earlier than had been anticipated.

It’s official: scientists say we're entering Earth's sixth mass extinction - ScienceAlert

Biologists have used conservative new estimates to prove that vertebrate species on Earth are disappearing faster than at any time since the extinction of the dinosaurs, and humans are now at risk of being wiped out.

"[The study] shows without any significant doubt that we are now entering the sixth great mass extinction event," one of the researchers, Paul Ehrlich from Stanford University in the US, said in a press release. Even worse, the research shows that we triggered the event ourselves.
