NEGEV DESERT Israel (Reuters) - An Israeli solar power company, Brenmiller Energy, says it has developed a new, more efficient way to store heat from the sun that could give a boost to the thermal solar power industry by enabling plants to run at full capacity night and day. By next year company founder Avi Brenmiller said he will have a 1.5 megawatt (MW), 15-acre (6-hectare) site in the Negev desert connected to Israel's national grid, and a number of 10 to 20-MW pilots abroad are expected to follow, which will produce electricity at a price which competes with power from fossil-fuelled plants. "A couple of years from now, not later than that, we will be putting full-size ...

ScienceAlert... A researcher has created a use-by-date label that decays as the same rate of food, in order to drastically reduce unnecessary food waste. Known as the Bump Mark label, this new bio-reactive expiry date is made from gelatine, a protein that reacts to environmental conditions such as temperature and light - and anything else that affects food. Developed by Sloveiga Pakstaite from Brunel University in London, the label has been named the UK winner of the James Dyson Award for innovatively tackling the global problem of food waste. Each year the UN estimates that seven MILLION tonnes of food is wasted in the UK alone, often because it’s passed it’s marked use by ...
A more efficient, lightweight and low-cost organic solar cell: Researchers broke the 'electrode barrier'
Post Date: 2014-09-20 06:03:08 by Tatarewicz

ScienceDaily For decades, polymer scientists and synthetic chemists working to improve the power conversion efficiency of organic solar cells were hampered by the inherent drawbacks of commonly used metal electrodes, including their instability and susceptibility to oxidation. Now for the first time, researchers at the University of Massachusetts Amherst have developed a more efficient, easily processable and lightweight solar cell that can use virtually any metal for the electrode, effectively breaking the "electrode barrier." This barrier has been a big problem for a long time, says UMass Amherst's Thomas Russell, professor of polymer science and engineering. "The ...
UN climate change: 1000 scientists say no

It’s a shocking 321-page report assembled by The Climate Depot: “More Than 1000 International Scientists Dissent Over Man-Made Global Warming Claims.” It names names. It lists reasons for the dissent. Reality is engineered consensus. But when that doesn’t work, “experts” just assert there is a consensus when there isn’t. “What the hell, let’s just say that ‘everybody agrees’ manmade warming is destroying Earth and we have ten minutes to solve it, and let’s get our friends in the press to shut out the naysayers. You know, media blackout.” Science is supposed to be about evidence and proof, not consensus. But that idea is ...
New explanation for origin of plate tectonics: What set Earth's plates in motion?

ScienceDaily... The mystery of what kick-started the motion of our earth's massive tectonic plates across its surface has been explained by researchers at the University of Sydney. "Earth is the only planet in our solar system where the process of plate tectonics occurs," said Professor Patrice Rey, from the University of Sydney's School of Geosciences. "The geological record suggests that until three billion years ago the Earth's crust was immobile so what sparked this unique phenomenon has fascinated geoscientists for decades. We suggest it was triggered by the spreading of early continents then eventually became a self-sustaining process." Professor Rey ...

Textbook theory behind volcanoes may be wrong
Post Date: 2014-09-15 08:29:04 by Tatarewicz

ScienceDaily: In the typical textbook picture, volcanoes, such as those that are forming the Hawaiian islands, erupt when magma gushes out as narrow jets from deep inside Earth. But that picture is wrong, according to a new study from researchers at Caltech and the University of Miami in Florida. New seismology data are now confirming that such narrow jets don't actually exist, says Don Anderson, the Eleanor and John R. McMillian Professor of Geophysics, Emeritus, at Caltech. In fact, he adds, basic physics doesn't support the presence of these jets, called mantle plumes, and the new results corroborate those fundamental ideas. "Mantle plumes have never had a sound physical ...

Scientists find quicker, more sustainable way to produce hydrogen fuel
Post Date: 2014-09-13 02:54:54 by Tatarewicz
0 Comments
Scientists in Scotland have just taken a huge step towards producing clean hydrogen fuel in a sustainable way. Unlike fossil fuels, hydrogen gas can be burned to generate electricity without producing toxic emissions. It’s produced easily from water through a process known as electrolysis, which uses electricity to break the bonds between hydrogen and oxygen, to release them as gas. But, and this is a big but, the problem is where that electricity comes from - current methods are driven by the burning of fossil fuels, which sort of defeats the whole point of making hydrogen fuel in the first place. This new method, however, developed by chemists from the University of Glasgow in ...

VIDEO: Boater Catches Explosive Volcanic Eruption, Startling Sonic Boom on CameraBy Courtney Spamer, MeteorologistSeptember 11, 2014; 4:46 AM ET Mount Tavurvur, a volcano in Papua New Guinea, erupted on Aug. 29, spewing ash and causing a shock wave and resultant sonic boom. While in a boat near the New Guinea coast, Phil McNamara caught a rare sight, the initial explosion of a volcano. Mount Tavurvur is known as a rather active volcano, one that caused many deaths and covered a nearby town in ash in 1994. Although a smaller eruption in comparison, the recent August explosion captured on video is a rare, close-up look. Following the explosive eruption, a shock wave emanated from the blast. ...

PressTV... A solar storm, which registers "extreme" on forecasters' scale, is barreling towards the Earth. It is yet to be known when the highly-charged ejecta from a solar eruption, which took place on Wednesday, will strike the Earth. Tom Berger, director of the National Oceanic and Atmospheric Administration (NOAA)’s Space Weather Prediction Center in Boulder, Colorado, said, "There's been a giant magnetic explosion on the sun." "Because it's pointed right at us, we'll at least catch some of the cloud" of highly energized and magnetized plasma that can disrupt Earth's magnetic sphere, which sometimes leads to temporary power grid ...
Biologists delay the aging process by 'remote control'
Post Date: 2014-09-10 01:15:37 by Tatarewicz

Activating a gene called AMPK in the nervous system induces the anti-aging cellular recycling process of autophagy in both the brain and intestine. UCLA biologists have identified a gene that can slow the aging process throughout the entire body when activated remotely in key organ systems. Working with fruit flies, the life scientists activated a gene called AMPK that is a key energy sensor in cells; it gets activated when cellular energy levels are low. Increasing the amount of AMPK in fruit flies' intestines increased their lifespans by about 30 percent—to roughly eight weeks from the typical six—and the flies stayed healthier longer as well. The research, published ...

Telegraph... For the first time, scientists have been able to send a simple mental message from one person to another without any contact between the two, thousands of miles apart in India and France. Research led by experts at Harvard University shows technology can be used to transmit information from one person's brain to another's even, as in this case, if they are thousands of miles away. "It is kind of technological realisation of the dream of telepathy, but it is definitely not magical," Giulio Ruffini, a theoretical physicist and co-author of the research, told AFP by phone from Barcelona. "We are using technology to interact electromagnetically with the ...

PHYSICIST MAKES WRY PREDICTION ABOUT THE HIGGS BOSON PARTICLE (NEWSER) – Stephen Hawking has already warned that aliens might wipe out the human race. Now another mild prediction: The Higgs Boson or "God" particle could cause a "catastrophic vacuum delay" that undermines space-time and destroys the universe, reports CNET via the Sunday Times. How so? Well, the particle "has the worrisome feature that it might become metastable at energies above 100bn gigaelectronvolts (GeV)," he writes in the introduction to a new book of scientist lectures called Starmus, reports Mic.com. But a particle accelerator that reaches 100GeV "would be larger than Earth, ...
