New York Governor Andrew Cuomo has announced "alarming levels" of radiation after water contaminated with radioactive tritium leaked from the Indian Point nuclear power plant. At one monitoring well, the radiation had spiked 65,000 percent. The plant’s owner, Entergy Corporation, has said the groundwater contamination at the plant does not pose a threat to the public. Environmentalists have long called for the closure of Indian Point, citing aging infrastructure and a history of operational issues.

An experienced German farmer of dairy herd recognized by his profession, Mr Gottfried Glockner, fed his cows between 1998 and 2002 with Bt176 maize silage. This GMO produced a new modified insecticide Bt and contained an antibiotic resistance marker gene. The only toxicological test, before being commercialized, was conducted by Novartis (subsequenly Syngenta) in the United States, and consisted by feeding 4 cows for 15 days, one cow died after a week.

The material at the heart of the lithium ion batteries that power electric vehicles, laptop computers and smartphones has been shown to impair a key soil bacterium. The study by researchers at the University of Wisconsin-Madison and the University of Minnesota is an early signal that the growing use of the new nanoscale materials used in the rechargeable batteries that power portable electronics and electric and hybrid vehicles may have untold environmental consequences.

Lakes around the world are rapidly warming #extinction #greenpeace

Lakes around the world are rapidly warming #extinction #greenpeace | Messenger for mother Earth | Scoop.it
Climate change is rapidly heating up lakes around the world, threatening freshwater supplies and ecosystems across the planet, according to a study spanning six continents.

More than 60 scientists took part in the research, published in the journal Geophysical Research Letters and announced today at the fall meeting of the American Geophysical Union.

"Our knowledge of how lakes are responding to global change has been lacking," said Henry Gholz, program director in the Division of Environmental Biology at the National Science Foundation, which funded the research. "That has made forecasting the future of lakes -- and the life and livelihoods they support -- very challenging. These newly reported trends are a wake-up call to scientists and citizens, including water resource managers and those who depend on freshwater fisheries."

 

The study found that lakes are warming an average of 0.61 degrees Fahrenheit each decade. That's greater than the warming rate of the oceans or the atmosphere, and it can have profound effects, the scientists say.


At the current rate, algal blooms, which ultimately rob water of oxygen, should increase by 20 percent over the next century. Some 5 percent of the blooms will be toxic to fish and animals.


Emissions of methane, a greenhouse gas 20 times more powerful than carbon dioxide, will increase 4 percent over the next decade. "Lakes are important because society depends on surface water for the vast majority of human uses -- not just for drinking water, but manufacturing, energy production, irrigation and crops," said paper co-author Stephanie Hampton of Washington State University. "Protein from freshwater fish is especially important in the developing world."

Out Of Nothing: Dynamical Casimir effect in metamaterial converts vacuum fluctuations into real photons #renewables

Out Of Nothing: Dynamical Casimir effect in metamaterial converts vacuum fluctuations into real photons #renewables | Messenger for mother Earth | Scoop.it

In the strange world of quantum mechanics, the vacuum state (sometimes referred to as the quantum vacuum, simply as the vacuum) is a quantum system's lowest possible energy state. While not containing physical particles, neither is it an empty void: Rather, the quantum vacuum contains fluctuating electromagnetic waves and so-called virtual particles, the latter being known to transition into and out of existence. In addition, the vacuum state has zero-point energy – the lowest quantized energy level of a quantum mechanical system – that manifests itself as the static Casimir effect, an attractive interaction between the opposite walls of an electromagnetic cavity. Recently, scientists at Aalto University in Finland and VTT Technical Research Centre of Finland demonstrated the dynamical Casimir effect using a Josephson metamaterial embedded in a microwave cavity. They showed that under certain conditions, real photons are generated in pairs, and concluded that their creation was consistent with quantum field theory predictions.


Researcher Pasi Lähteenmäki discussed the challenges he and his colleagues – G. S. Paraoanu, Juha Hassel and Pertti J. Hakonen – encountered in their study. Regarding their demonstration of the dynamical Casimir effect using a Josephson metamaterial embedded in a microwave cavity at 5.4 GHz, Lähteenmäki tells Phys.org that the main challenge in general is to get high-quality samples. In addition, Lähteenmäki adds, they had to ensure that the origin of the noise is quantum and not some unaccounted source of excess noise, such as thermal imbalance between the environment and the sample, or possibly leakage of external noise.

 

Modulating the effective length of the cavity by flux-biasing the SQUID (superconducting quantum interference device) metamaterial had its challenges as well. "The pump signal needs to be rather strong, yet at the same time one wants to be sure that no excess noise enters the system through the pump line, Lähteenmäki notes, "and good filtering means high attenuation, which is a requirement contradictory to a strong signal. Also," Lähteenmäki continues, "at 10.8 GHz the pump frequency is rather high – and at that frequency range both the sample and the setup is rather prone to electrical resonances which can limit the usable frequencies." In short, the flux profile needs to be such that the pumping doesn't counteract itself. In addition, trapping flux in SQUID loops can also become a problem, limiting the range of optimal operating points and causing excess loss.

 

The researchers also showed that photons at frequencies symmetric with respect to half the modulation frequency of the cavity are generated in pairs. "In general, with frequency locked signal analyzers today the extraction of this correlation is not particularly problematic – especially since the low noise amplifier noise is not correlated at different frequencies," Lähteenmäki explains. That said, issues related to data collection and averaging include amplifier gain drift and phase randomization of the pump signal (relative to the detection phase) if the state of the generator is changed. "The noise temperature of the low noise amplifier sets some limits to the amount of data that needs to be collected, especially in the case where one is operating in the regime of low parametric gain."

Virus particles engineered to hold enzymes that generate carbon-free hydrogen fuel #biology #science

Virus particles engineered to hold enzymes that generate carbon-free hydrogen fuel #biology #science | Messenger for mother Earth | Scoop.it

How to put a hydrogen fuel factory inside the shell of a virus? Living cells are masters of compartmentalization. Whether it’s stuffing DNA inside the nucleus or cramming energy-generating machinery into the rod-shape organelles called mitochondria, biology separates tasks into specialized compartments within cells to make it easier to do specific jobs without interference.

 

Researchers in Indiana are following that same strategy to isolate enzymes inside hollow virus-made nanoparticles in order to make hydrogen for fuel. The process does not yet produce enough hydrogen to compete with commercial alternatives. But the researchers, whose results appear today in Nature Chemistry, already have their sights set on improvements aimed at generating large amounts of fuel cheaply.
