Paper-thin printed solar cells could provide power for 1.3 billion people

The cost of solar power has declined dramatically over the past few decades, from $40 per watt in 1977 to $0.74 per watt in 2013. This trend is expected to accelerate as improvements in efficiency and new technologies come online. This is good news for citizens of developed countries who want to make the switch to a cleaner and increasingly cheaper energy source. The shift to solar may be most dramatic for those living in developing countries. Thanks to inexpensive printed solar cells, 1.3 billion people currently without electricity may be able to plug in for the first time.

Researchers tackle methane emissions with gas-guzzling bacteria

An international research team co-led by a Monash biologist has shown that methane-oxidising bacteria - key organisms responsible for greenhouse gas mitigation - are more flexible and resilient than previously thought.

Industrial processes such as petroleum production and waste treatment release large amounts of the methane, carbon dioxide and hydrogen into the atmosphere.


"By using these gas-guzzling bacteria, it's possible to convert these gases into useful liquid fuels and feeds instead," Dr Greening said.


Australia First to Receive Ocean Wave Generated Zero-Emission Electricity (Energy Mafia is on its knees)

The world is in desperate need of alternative energy, and Australia just rode the wave, quite literally, into a new energy paradigm. Using the Perth Wave Energy Project's CETO 5 wave energy generators developed by Carnegie Wave Energy Limited, the movement of the ocean is creating renewable, sustainable energy – which can even be used to make potable water through desalinization.

MDMA approved for final trials to treat PTSD before possible legalization

FDA could make drug legal by 2021 if phase three tests involving controlled dosage and talk therapy are shown to alleviate post-traumatic stress disorder

The US Food and Drug Administration (FDA) has given the green light to phase three trials of MDMA to treat post-traumatic stress disorder, the final phase of validation required to turn the party drug into a legal medicine.

All powered up - researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times

University of California, Irvine researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement. The breakthrough work could lead to commercial batteries with greatly lengthened lifespans for computers, smartphones, appliances, cars and spacecraft.

Japanese man is first to receive 'reprogrammed' stem cells from another person

World-first transplant to treat macular degeneration could augur rise of iPS cell banks.

On 28 March, a Japanese man in his 60s became the first person to receive cells derived from induced pluripotent stem (iPS) cells that had been donated by another person.

The surgery is expected to set the path for more applications of iPS cell technology, which offers the versatility of embryonic stem cells without the latter's ethical taint. Banks of iPS cells from diverse donors could make stem cell transplants more convenient to perform, while slashing costs.

Climate change made catastrophic coral bleaching 175 times more likely

Warm ocean waters that sucked the color and vigor from sweeping stretches of the world's greatest expanse of corals last month were driven by climate change, according to a new analysis by scientists, who are warning of worse impacts ahead.

Climate change made it 175 times more likely that the surface waters of the Coral Sea, which off the Queensland coastline is home to Australia's Great Barrier Reef, would reach the record-breaking temperatures last month that bleached reefs, modeling analysis showed.
