In the quest for sustainable alternative energy and fuel sources |

Through photosynthesis, plants convert sunlight, water, and CO2 into sugars, multicarbon molecules that fuel cellular processes. CO2 is thus both the precursor
to the fossil fuels that are central to modern life as well as the by-product of burning those fuels. The ability to generate synthetic liquid fuels from stable, oxygenated carbon precursors such as CO2 and carbon monoxide (CO) is reminiscent of photosynthesis in nature and is a transformation that is desirable in artificial systems. In the quest for sustainable alternative energy and fuel sources, one viable solution may be the conversion of the greenhouse gas carbon dioxide (CO2) into liquid fuels.

Researchers at Linköping University in Sweden have created analog and digital electronics circuits inside living plants |

The article featured in the journal Science Advances demonstrates wires, digital logic, and even displays elements - fabricated inside the plants - that could develop new applications for organic electronics and new tools in plant science. Early efforts to introduce electronics in plants were attempted by Assistant Professor Daniel Simon, leader of the LOE's bioelectronics team, and Professor Xavier Crispin, leader of the LOE's solid-state device team, but a lack of funding from skeptical investors halted these projects. Thanks to independent research money from the Knut and Alice Wallenberg Foundation in 2012, Professor Berggren was able to assemble a team of researchers to reboot the project.

Price of solar energy in the U.S. has fallen to 5¢/kWh |

Solar energy pricing is at an all-time low, according to a new report released by Lawrence Berkeley National Laboratory (Berkeley Lab). Driven by lower installed costs, improved project performance, and a race to build projects ahead of a reduction in a key federal incentive, utility-scale solar project developers have been negotiating power sales agreements with utilities at prices averaging just 5¢/kWh.                              Read More: 


These prices reflect receipt of the 30% federal investment tax credit, which is scheduled to decline to 10% after 2016, and would be higher if not for that incentive. By comparison, average wholesale electricity prices across the United States ranged from 3 to 6 cents/kWh in 2014, depending on the region.

Solving mysteries of the interstellar medium |

Date:   August  2015
This artist's conception symbolically represents complex organic molecules, known as polycyclic aromatic hydrocarbons, seen in the early universe. These large molecules, comprised of carbon and hydrogen, are among the building blocks of life. NASA's Spitzer Space Telescope is the first telescope to see polycyclic aromatic nitrogen heterocycles so early ... 10 billion years further back in time than seen previously.  



Despite intense research efforts over the last few decades, an assignment of the DIBs has remained elusive, although indications exist that they may arise from the presence of large hydrocarbon molecules in interstellar space. Recent experiments lend novel credibility to this hypothesis.

Sunlight Striking Earth’s Surface in One Hour Delivers Enough Energy to Power World Economy for the Entire Year

In April 1954, top scientists gathered in Washington, D.C., to hear something new: voice and music broadcast by a solar-powered radio transmitter. Scientists at Bell Labs in New Jersey were demonstrating their invention, the first practical solar cell, which was made of silicon. This breakthrough paved the way for the solar revolution taking place today on rooftops and in massive ground-mounted solar farms around the world. Read More |

Closing in on the secrets of plant photosynthesis |

The new technique essentially has brought the picture into sharper focus. What the technicians see is a system in which "antenna" proteins capture light and feed them into a kind of molecular reactor. One difficulty with fully understanding the process is that, unlike the parts of a solar panel, which are rigid and designed to last, the crucial proteins in the photosystem of a plant are dynamic, and don't last very long before they fall apart. The plant then regenerates these structures. "Even though nature has had millions of years to develop and optimize photosynthesis, there are still outstanding and unknown questions about how photosynthesis operates. It's truly a scientific challenge."

Vatican Climate Change Summit to Frame Action as Moral Imperative

Pope Francis urges action on climate change

Rare meeting between scientists and representatives from all major religions will highlight moral duty to combat climate change |

Pope Francis has already said that he believes global warming is mostly man-made and that a Christian who does not protect God’s creation “is a Christian who does not care about the work of God”. He has also linked environmental exploitation to social and economic inequality, saying: “An economic system centred on the god of money needs to plunder nature to sustain the frenetic rhythm of consumption that is inherent to it.” The summit – which will include speakers and representatives from all major religions – has brought about a rare meeting of minds between scientists and religious officials on climate change, even if they frame their arguments in different ways.

Photosynthesis has unique isotopic signature |

Photosynthesis leaves behind a unique calling card, a chemical signature that is spelled out with stable oxygen isotopes, according to a new study in Science. The findings suggest that similar isotopic signatures could exist for many biological processes, including some that are difficult to observe with current tools.

"We've found a new type of biosignature," said co-lead author Laurence Yeung, an assistant professor of Earth science at Rice University. "We show that plants and plankton impart this type of biosignature on the oxygen they produce during photosynthesis. "Yeung, who joined Rice in January, conducted the study with colleagues at the University of California, Los Angeles. Isotopes are versions of an element that differ in their atomic weights. For example, most oxygen atoms contain eight protons and eight neutrons and are represented by the symbol O-16. More than 99.9 percent of Earth's oxygen is O-16, but two heavier oxygen isotopes exist in trace amounts: O-17, which contains one extra neutron, and O-18, which has two extra.

"Looking at oxygen through the lens of clumped isotopes will give us a lot of new information about how oxygen is made and consumed by plants," said study co-lead author Jeanine Ash, a graduate student at UCLA. "I'm very excited about what this approach holds for the future." Read More | Isotopes of oxygen | There are three stable isotopes of oxygen that lead to oxygen (O)
having a standard atomic mass of 15.9994(3) u. Also 10 unstable isotopes have been characterized.

Second Hand Smoke And Mirrors |

APR 9, 2015 | "Merchants of Doubt" trying to derail action on climate change |
No person today would grant equal time to the Surgeon General and a Tobacco Lobbyist in a debate about the dangers of smoking. For 50 years, Big Tobacco — one of Berman’s first clients — was allowed to play point/counterpoint with mainstream scientists. [Breathing other people's smoke is known as passive smoking or second-hand smoking] As a society, we’ve accepted the injurious effects of smoking and moved on. Today, with Climate Change and Air Pollution, the same can’t be said. We’re still allowing the same old debate to continue on cable news, in newspapers, in Op-ed pages. And our news outlets still cover the issue in terms one opinion versus another, not as fact vs. fiction. Read More |

Does Calif. capture enough water to justify new dams |

|If taxpayers do front some money, what are they really buying? Are they propping up a project with shaky economics, or buying something with real public value? |Should California build dams, reservoirs to help with future droughts?|Sacramento Bee 6/6/14 READ MORE Former Hewlett Packard CEO Carly Fiorina on Monday blamed environmentalists for what she called a "man-made" drought in California. “With different policies over the last 20 years, all of this could be avoided,” Fiorina, a likely 2016 Republican presidential contender, said in an interview with radio host Glenn Beck. “Despite the fact that California has suffered from droughts for millennia, liberal environmentalists have prevented the building of a single new reservoir or a single new water conveyance system over decades during a period in which California’s population has doubled.”

NextGen Climate, the climate-focused political group run by billionaire environmentalist Tom Steyer, on Monday evening called Fiorina's comments "irrational."
"For a science denier to opine that Democrats caused the drought in California is about as irrational as believing someone who failed at running a business in California and then failed as a candidate for office in California has any cause to be running for the highest office in the land," Bobby Whithorne, the group's spokesman, said in a statement.The Sierra Club, a national environmental group, disputed Fiorina's assertion that more dams and reservoirs would have lessened the impact of the drought.
"For more than 100 years, environmentalists have failed to stop the damming of nearly every significant river in California. And yet all of the hundreds of dams out there have done nothing to produce rain or snow pack over the last four years. That's because you can't store what's not there," said Kathryn Phillips, director of Sierra Club's California chapter. "We simply don't have rain or snow pack and are suffering the worst California drought since water agencies and weather trackers started keeping records."
"What we are seeing is exactly what climate scientists have predicted would happen in California with the onset of human-caused climate disruption: Weather and precipitation would become less predictable and droughts would become more frequent and more severe," Phillips added.

This Redesigned Pedestrian Overpass In Barcelona Is Like A Mini High Line

A pedestrian bridge in Barcelona is being redesigned as a place where people might actually want to spend time. Surrounded by plant-covered walls, the new design includes shaded spaces to sit and look at views of the city. Smog-eating concrete helps clear the surrounding air, and glow-in-the-dark pavement lights the path at night. The photocatalytic concrete used in the new bridge absorbs pollution from the cars below. It's an experimental product that the architects wanted to test. "Using this in reality will give the possibility to measure how much and how well it works," says Casamor. "We don’t have much to lose, and if it works it would be a good choice for using in other more extensive parts of the city." READ MORE |

Astronomers find dust, PANHs in early Universe |

March 2, 2015
Source: University of Copenhagen - Niels Bohr Institute
Summary: Dust plays an extremely important role in the universe -- both in the formation of planets and new stars. But dust was not there from the beginning and the earliest galaxies had no dust, only gas. Now an international team of astronomers, led by researchers from the Niels Bohr Institute, has discovered a dust-filled galaxy from the very early universe. The discovery demonstrates that galaxies were very quickly enriched with dust particles containing elements such as carbon and oxygen, which could form planets. The results are published in the scientific journal, Nature.

New flow battery to keep big cities lit, green and safe |


February 25, 2015 |  RICHLAND, Wash. –  Ensuring the power grid keeps the lights on in large cities could be easier with a new battery design that packs far more energy than any other battery of its kind and size. The new zinc-polyiodide redox flow battery, described in Nature Communications, uses an electrolyte that has more than two times the energy density of the next-best flow battery used to store renewable energy and support the power grid. And its energy density is approaching that of a type of lithium-ion battery used to power portable electronic devices and some small electric vehicles. "With improved energy density and inherent fire safety, flow batteries could provide long-duration energy storage for the tight confines of urban settings, where space is at a premium," said Imre Gyuk, energy storage program manager at the Department of Energy's Office of Electricity Delivery and Energy Reliability, which funded this research. "This would enhance the resiliency and flexibility of the local electrical grid."
