Roads made of solar panels may solve energy crisis

London, September 9 (ANI): The U.S. Department of Transportation is funding a new research project aimed at replacing asphalt with solar panels as the basic material for making roads, in a bid to solve the crisis of electricity.

As part of the scheme, a U.S. firm called Solar Roadways has won a grant of 100,000 dollars from the Government to carry on with its work on a prototype glass solar cell panel that may one day turn motorways into major energy sources.

It is expected that these panels will be capable of generating enough power to support local communities, according to reports.

The panels would also be covered with a mosaic of small lights, which could be illuminated to provide road markings, and warning messages to drivers.

They could also be embedded with heaters to keep the road clear by melting snow and ice.

The company believes that a four-lane, one-mile stretch of road made from the 12 ft by 12 ft panels, each capable of producing 7.6 kilowatt hours of electricity each day, can generate enough power for 500 homes.

Solar Roadways plans to develop its idea to allow the energy produced to be channelled into the national grid, as well as sold to drivers of electric cars on the roadside.

“This feature packed system will become an intelligent highway that will double as a secure, intelligent, decentralised, self-healing power grid which will enable a gradual weaning from fossil fuels,” the Telegraph quoted the company as saying in a statement. (ANI)

Even graduates are showing interest in this special course, as they know it will prepare them for many employment opportunities.

“This course assures job for us. There are job opportunities in tourism sector as hundreds of tourists come to visit Himachal…. We are not only learning cooking and catering but also this course is teaching us the real sense of hospitality… this will tell us how to help and guide tourists,” said a graduate trainee.

Tourism is an important employment generating sector in Himachal Pradesh and it is the mainstay in Kufri which attracts large number of tourists to enjoy snow falls. By Hemant Chauhan (ANI)

Scientists create world’s smallest semiconductor laser

Washington, August 31 (ANI): Researchers at the University of California (UC), Berkeley, have created the world’s smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule, an invention that breaks new ground in the field of optics.

The UC Berkeley team not only successfully squeezed light into such a tight space, but found a novel way to keep that light energy from dissipating as it moved along, thereby achieving laser action.

While it is traditionally accepted that an electromagnetic wave – including laser light – cannot be focused beyond the size of half its wavelength, research teams around the world have found a way to compress light down to dozens of nanometers by binding it to the electrons that oscillate collectively at the surface of metals.

This interaction between light and oscillating electrons is known as surface plasmons.

Scientists have been racing to construct surface plasmon lasers that can sustain and utilize these tiny optical excitations.

However, the resistance inherent in metals causes these surface plasmons to dissipate almost immediately after being generated, posing a critical challenge to achieving the buildup of the electromagnetic field necessary for lasing.

Zhang and his research team took a novel approach to stem the loss of light energy by pairing a cadmium sulfide nanowire – 1,000 times thinner than a human hair – with a silver surface separated by an insulating gap of only 5 nanometers, the size of a single protein molecule.

In this structure, the gap region stores light within an area 20 times smaller than its wavelength.

Because light energy is largely stored in this tiny non-metallic gap, loss is significantly diminished.

With the loss finally under control through this unique “hybrid” design, the researchers could then work on amplifying the light.

Trapping and sustaining light in radically tight quarters creates such extreme conditions that the very interaction of light and matter is strongly altered, the study authors explained.

“This work shatters traditional notions of laser limits, and makes a major advance toward applications in the biomedical, communications and computing fields,” said Xiang Zhang, professor of mechanical engineering and director of UC Berkeley’s Nanoscale Science and Engineering Center.

The achievement helps enable the development of such innovations as nanolasers that can probe, manipulate and characterize DNA molecules; optics-based telecommunications many times faster than current technology; and optical computing in which light replaces electronic circuitry with a corresponding leap in speed and processing power.

Scientists hope to eventually shrink light down to the size of an electron’s wavelength, which is about a nanometer. (ANI)

World’s largest bats on the verge of extinction in Peninsular Malaysia due to hunting

Washington, August 26 (ANI): The world’s largest species of fruit bat, Pteropus vampyrus, could be driven to extinction in Peninsular Malaysia at the current hunting rate, scientists have warned.

They say that around 22,000 of these bats, also known as “large flying fox”, are legally hunted each year in Peninsular Malaysia, a level that is unsustainable based on their estimates of the number of bats in the country.

Dr Jonathan Epstein, a veterinary epidemiologist at Wildlife Trust, surveyed 33 roost sites across Peninsular Malaysia and repeatedly counted the numbers of bats at eight sites between 2003 and 2007.

Writing about their work in the British Ecological Society’s Journal of Applied Ecology, he and his colleagues revealed that they compared this data along with the number of hunting licenses issued by the Malaysian Department of Wildlife and National Parks using computer models to see whether the number of bats hunted each year was sustainable.

The researchers also used satellite transmitters attached to bats to see how far the species migrated, and found that they travelled from Malaysia to Indonesia and Thailand.

The Malaysian Department of Wildlife and National Parks, which regulates the hunting of flying foxes, also participated in the current study because there was interest in generating data to help assess the impact of current hunting rates.

It was observed that, based on the average number of licenses issued each year, around 22,000 flying foxes per year were allowed to be killed in Peninsular Malaysia, yet this rate was unsustainable even with the most optimistic population level of 500,000 assumed by their model.

The researchers reckon that this level of hunting will drive the species to extinction in between six and 81 years.

Epstein says: “Our models suggest that hunting activity over the period between 2002 and 2005 in Peninsular Malaysia is not sustainable, and that local populations of Pteropus vampyrus are vulnerable to extinction. Now that we know that these bats migrate between Malaysia, Thailand and Indonesia, coordinated assessments of their status throughout their range will be important for developing effective management strategies. Any additional hunting pressure on this species that occurs in Thailand or Indonesia may hasten the population’s decline.”

Epstein and his colleagues suggest that a temporary ban be imposed on hunting flying foxes so that their population can recover, and the species can be saved from local extinction.

“Our study illustrates that bats, like other migratory species, require comprehensive protection by regional management plans across their range,” says Epstein.

The study’s findings have prompted the Department of National Parks and Wildlife to review their policy on bat hunting. (ANI)

Tourist inflow on rise in Manali

Manali, Aug 26 (ANI): Recession might have slowed down tourism businesses elsewhere, but Manali in Himachal Pradesh seems to be untouched by it.

According to officials, tourist inflow has risen by 25 per cent this year.

“Lot of tourists are arriving in Kullu district in general and Manali in particular. This year, there’s been a definite increase in the number. As per the estimations, there’s an increase of 25 per cent compared to last year. If we see global recession, it might sound paradoxical,” said Rajeshwar Goel, district tourism officer, Kullu.

The main reason for tourists getting attracted to Manali is its cool weather. Sometimes its snows even in the month of June while the rest of the country reels under scorching summer.

Manali is also being a centre for adventure sports.

The very unique characteristics of Manali will continue to attract tourists, feels Himanshu, a tour and travel operator.

“We can say there’s 20 per cent boom in overall business. We expect this trend to increase. Himachal Pradesh is a very safe destination and tourist friendly destination. It’s a very rich destination. You can find diverse interest here,” said Himanshu.

Tourism is the mainstay of the region’s economy. Thousands of tourists come here every year generating business and employment for people.

More than 10 million tourists throng Himachal Pradesh as most of them visit Kullu-Manali region. By Prem Thakur (ANI)

How to make a lung

Washington, Aug 18 (ANI): Scientists from University of Pennsylvania have shed light on how lungs are developed in the body.

They have identified a tissue-repair-and-regeneration pathway in the human body, including wound healing that is essential for the early lung to develop properly.

The researchers have also discovered two molecules in this pathway, Wnt2 and Wnt2b that play a key role in early lung development.

“We wanted to know the answer to a seemingly simple question: What is required to generate the lung in mammals?” said senior author Dr Edward Morrisey, Associate Professor of Medicine and Cell and Developmental Biology at the University of Pennsylvania School of Medicine.

“Wnt molecules are important for lung growth and we think that some of the molecules in the Wnt pathway are needed to specify lung progenitor cells and if not enough cells are ‘told’ to make a lung, an animal develops a faulty, smaller organ or even no lung,” he added.

Understanding how a lung develops is important in treating or preventing a host of lung and pulmonary diseases in children.

In the developing embryo, the lung, pancreas, liver, thyroid, and stomach all come from the foregut region, which starts out looking like a long tube.

“These organs bud from this undifferentiated tube and go on to develop into specific tissue types. The lung is one of the last to bud off the foregut during development,” said Morrisey.

The team focused on the Wnt pathway to see where and when Wnt molecules were expressed along the foregut tube, even before the lung starts to become a recognizable organ.

They found that the Wnt proteins Wnt2 and Wnt2b are expressed in the cells surrounding the foregut, right where the lung will eventually form. When they are knocked out, the animals completely lacked lungs.

Morrisey surmised that Wnt2 and Wnt2b were required to specify the early progenitors for the lung in the foregut.

The Morrisey lab showed that activation of the Wnt pathway resulted in formation of lung progenitors in both the esophagus and stomach where they are normally excluded.

“The ability of Wnt to program esophagus and stomach endoderm to a lung fate points to the critical role this pathway plays in lung development and suggests the possible use of Wnt in generating lung epithelium from non-lung sources,” said Morrisey.

The findings are described this week in Developmental Cell. (ANI)

Your cars may soon be powered by urine

New York, July 15 (ANI): Could it be possible to run your car on urine? Well, it may be, if Ohio University scientists are to be believed.

And their confidence stems from the fact that they have found a novel way to produce hydrogen energy from urine.

According to Discovery News, the scientists used a nickel-based electrode to make cheap hydrogen from urine.

When the research team led by professor Gerardine Botte stuck the electrode into a pool of urine, and applied an electrical current, hydrogen gas was released, which was used in fuel cells.

The prototype is about three inches by three inches, and is capable of generating 500 milliwatts of power.

The scientists hope to create commercial versions of the technology.

Botte expects that the fuel-cell urine-powered car could theoretically travel 90 miles per gallon.

“One cow can provide enough energy to supply hot water for 19 houses. Soldiers in the field could carry their own fuel,” the New York Daily News quoted him as saying.

The researchers focussed their study on urea, a urine by-product.

“Urea is a byproduct of a lot of cities and farms, but even if you take all the people and all the animals, there’s not enough to run the world,” said University of Georgia professor John Stickney.

He added that though applications using urine won’t be available to consumers for quite some time, it’s definitely worth developing.

“We are going to have to put together a lot of greener ways to collect energy that don’t produce greenhouse gases and don’t require us to go to war,” he added. (ANI)

New military robot to fuel itself by gobbling up dead bodies

Washington, July 15 (ANI): A Maryland company under contract to the Pentagon is working on a steam-powered robot that would fuel itself by gobbling up whatever organic material it can find – grass, wood, old furniture, or even dead bodies.

Robotic Technology Inc.’s Energetically Autonomous Tactical Robot (EATR) “can find, ingest, and extract energy from biomass in the environment (and other organically-based energy sources), as well as use conventional and alternative fuels (such as gasoline, heavy fuel, kerosene, diesel, propane, coal, cooking oil, and solar) when suitable,” reads the company’s Web site.

Animal and human corpses contain plenty of energy, and they’d be plentiful in a war zone.

EATR will be powered by the Waste Heat Engine developed by Cyclone Power Technology of Pompano Beach, Florida, which uses an “external combustion chamber” burning up fuel to heat up water in a closed loop, generating electricity.

The advantages to the military are that the robot would be extremely flexible in fuel sources and could roam on its own for months, even years, without having to be refueled or serviced.

Upon the EATR platform, the Pentagon could build all sorts of things – a transport, an ambulance, a communications center, even a mobile gunship.

Robotic Technology is presenting EATR as an essentially benign artificial creature that fills its belly through “foraging,” despite the obvious military purpose. (ANI)

Government of India scheme to protect women from economic slow down

Seoul, June 26 (ANI): Union Minister for Women and Child Development Krishna Tirath has said that the Indian Government is making efforts to protect women from economic slow down and also enable them to uplift themselves.

Addressing the Plenary Session of 3rd East Asia Gender Equality Ministerial meeting at Seoul, South Korea on Thursday, the Minister said, ” The Self help group movement is being strengthened further to mobilize more and more women for income generating activities with linkage to micro credit.”

Speaking about the impact of economic crisis on women, on their health, nutritional level and their economic sustainability, Tirath said that Indian Government is committed to uplift women in every sphere of life and it is contemplating to increase reservation for women upto 50 per cent in local Government institutions, which is 33 per cent at the moment.

“A Bill to reserve one-third seats for women in Parliament and Legislative Assemblies is also under active contemplation, she added.

The Minister offered to the East Asian Countries for training in India in areas of gender budgeting, prevention of trafficking, self help group, micro finance and prevention of domestic violence.

She also met Minister of Gender Equality of Republic Korea and discussed the scope of collaboration between the countries in women related issues.

Tirath is participating for three-days in the Gender Equality meeting at Seoul. (ANI)

Revolutionary Wolfram ‘knowledge engine’ goes live

London, May 19(ANI): Wolfram Alpha, the revolutionary web tool that calculates and computes your queries instead of directing you to other sources of information, has gone live.

The new system, being hailed as a significant rival to search giant Google, is the brainchild of British-born physicist Stephen Wolfram, reports the BBC.

The online ‘computational knowledge engine’ was unveiled in late April and since then has been publicly demonstrated and some people have had a chance to run queries through it.

Typically, the results it provides are annotated pages of data rather than a simple list of other sites that might help resolve a user’s query.

Users can ask known facts from Wolfram Alpha, such as the height of mountains, or it can be asked to generate new information such as up to date figures for a nation’s GDP.

It can also handle complicated mathematical queries, plot statistics and produce charts of natural events.

The data it consults is chosen and managed by staff at Wolfram Research who ensure it can be displayed by the system.

Behind the scenes, Wolfram Alpha has about 10,000 CPUs spread across five data centres that it draws on when generating answers.

During a demonstration at Harvard University’s Berkman Center for Internet and Society, Wolfram said: “Our goal is to make expert knowledge accessible to anyone, anywhere, anytime.”

Wolfram dismissed claims that the system is a potential Google killer and instead presents it as a way for people to get more out of the information on the web. (ANI)

Blood cells can be reprogrammed to act as embryonic stem cells

Washington, Apr 21 (ANI): Embryonic stem cells have long been coveted for their potential to treat a multitude of diseases. Now, researchers have successfully reprogrammed cells found in circulating blood into cells that are molecularly and functionally indistinguishable from embryonic stem cells.

The new study may provide a readily accessible source of stem cells and an alternative to harvesting embryonic stem cells.

“Our findings provide the first proof that cells from human blood can morph into stem cells,” said senior study author Dr George Q. Daley, an investigator for the Howard Hughes Medical Institute at Children’s Hospital, Boston.

“Making pluripotent stem cells from blood, which is one of the easiest tissues to obtain, provides an easy strategy for generating patient-specific stem cells that are valuable research tools and may one day be used to treat a number of diseases,” he added.

To produce the new stem cells called pluripotent (iPS), the researchers collected the blood from a 26-year-old male donor.

From the blood sample, they isolated CD34+ cells, a type of stem cell that produces only blood cells, and cultured them in growth factors for six days to increase their number.

During the culture, the scientists infected the CD34+ cells with viruses carrying reprogramming factors, genes normally expressed in embryonic stem cells that can reset the blood cells to an embryonic state.

Colonies of cells exhibiting physical characteristics similar to embryonic stem (ES) cells appeared about two weeks after the procedure.

In further studies, the iPS cells readily developed into clusters of cells called embryoid bodies from which cells of virtually any type can develop.

“Not only has this work identified a new programmable cell type, but the cells are easy to obtain and analyze in many research laboratories and bone marrow transplantation centers around the world,” said Dr Grover C. Bagby, Professor of Medicine and Molecular and Medical Genetics at Oregon Health and Science University.

The study appears online in journal Blood. (ANI)

UPDATE 1-Entergy NY Indian Pt 3 reactor reonnects to grid

(Releads with reconnection to grid)

NEW YORK, April 15 (Reuters) – Entergy Corp’s (ETR.N) 1,025-megawatt Unit 3 at the Indian Point nuclear power plant near New York City reconnected to the power grid Wednesday afternoon after a 35-day refueling outage, the company said.

The unit had been shut since March 11 for scheduled maintenance and refueling. By late Wednesday afternoon, it was operating at 28 percent of production capacity, said Jerry Nappi, Indian Point spokesman for Entergy.

The 2,045 MW Indian Point station is located in Buchanan in Westchester County about 45 miles north of New York City. The station has two units: the 1,020 MW Unit 2 and the 1,025 MW Unit 3, which entered service in 1973 and 1976.

Unit 2 continued to operate at full power early Wednesday.

Before it shut on March 11 to refuel, Unit 3 had operated for 678 consecutive days, a U.S. record for continuous operation for Westinghouse pressurized water reactors, Entergy said.

One MW powers about 800 homes in New York.

Entergy, of New Orleans, owns and operates about 30,000 MW of generating capacity, markets energy commodities and transmits and distributes power to 2.7 million customers in Arkansas, Louisiana, Mississippi and Texas. (Reporting by Joe Silha and Bernie Woodall, editing by John Picinich)

Japan to assist Jordan in nuclear energy development

Tokyo – Japan signed an agreement Tuesday to offer Jordan assistance in developing nuclear power plants, the Ministry of Economy, Trade and Industry said. The Japanese government agreed to help the Middle Eastern nation introduce nuclear power generation and guarantee non-proliferation of nuclear technology, the ministry said.

With Japan’s support, Jordan is aiming to become self-sufficient in generating energy by 2030 and plans to begin operating a nuclear plant by 2017.

The agreement was signed by Jordan’s King Abdullah II, who is on a three-day visit to Japan, and Foreign Minister Hirofumi Nakasone.

The two governments agreed to outline continued cooperation in development of nuclear technology.

Japan manages 53 reactors since it began developing the technology 50 years ago, the ministry said. (dpa)

G20 outcome will build confidence: Spanish PM

London, April 3 (EFE) Spanish Prime Minister Jose Luis Rodriguez Zapatero said the agreement reached Thursday at the G20 summit here would generate the confidence needed for the global recession to ‘touch bottom’ in the second half of the year.

He also announced at a post-summit press conference that Spain would contribute some 4 billion euros ($5.38 billion) of the $750 billion in new money that will be placed at the disposal of the International Monetary Fund (IMF) to help poor and developing economies.

After the summits in Washington and London, Spain, the world’s eighth-biggest economy, has consolidated its position in the G20 as ‘a power in international circles’, the premier said.

Regarding the accords adopted Thursday in London, Zapatero emphasised the support for ending the lack of financial transparency and the ‘impunity’ of tax havens.

‘Today, the beginning of the end of the tax havens began,’ Zapatero said, noting that at the summit, the respective economy and finance ministers devised steps to sanction countries blacklisted for failing to cooperate with efforts against tax evasion.

With this accord, the differences between the French-German bloc and the US bloc regarding the need to adopt new spending programmes that boost the economy receded.

In Zapatero’s judgement, there is general agreement that the stimulus efforts made to date ‘has no precedent’ and that the approved plans are beginning to have an effect in the economic realm.

Spain, Zapatero said, has initiated one of the largest fiscal expansion plans, amounting to more than two percent of gross domestic product.

The unity shown by the G20, he added, contributed to generating confidence and confirming that in the second half of 2009 the recession will bottom out and ‘the prospect is for recovery’, noting that ‘touching bottom would certainly be a positive expectation’.

The Spanish prime minister said that the G20 nations likewise committed to stricter oversight and supervision of financial markets to prevent the recurrence of the kind of activities that caused ‘the most serious economic recession since World War II’.

He also underlined the need of commitment to the Millennium Development Goals (MDGs) set by the United Nations nearly a decade ago.

‘History will judge us, above all, by the willpower we put into the fight against poverty and misery,’ he warned.

Olive oil protects against heart attack, stroke

Washington, Apr 2 (ANI): Portuguese researchers have identified a vital component of olive oil that gives greatest protection from heart attack and stroke.

Lead researcher Fatima Paiva-Martins from University of Porto has discovered an antioxidant called DHPEA-EDA that protects red blood cells from damage more than any other part of olive oil.

“These findings provide the scientific basis for the clear health benefits that have been seen in people who have olive oil in their diet,” said Paiva-Martins.

During the study, research team led by Paiva-Martins compared the effects of four related polyphenolic compounds on red blood cells subjected to oxidative stress by a known free radical generating chemical.

Heart disease is caused partly by reactive oxygen, including free radicals, acting on LDL or “bad” cholesterol and resulting in hardening of the arteries. Red blood cells are particularly susceptible to oxidative damage because they are the body’s oxygen carriers.

They found that DHPEA-EDA was the most effective and protected red blood cells even at low concentrations.

The new discovery, Paiva-Martins believes, can lead to the production of “functional” olive oils specifically designed to reduce the risk of heart disease.

Scientists discover new possibilities for hydrogen-producing algae

Washington, March 25 (ANI): Researchers studying a hydrogen-producing, single-celled green alga, Chlamydomonas reinhardtii, have unmasked a previously unknown fermentation pathway that may open up possibilities for increasing hydrogen production.

C. reinhartii, a common inhabitant of soils, naturally produces small quantities of hydrogen when deprived of oxygen. Like yeast and other microbes, under anaerobic conditions this alga generates its energy from fermentation.

During fermentation, hydrogen is released though the action of an enzyme called hydrogenase, powered by electrons generated by either the breakdown of organic compounds or the splitting of water by photosynthesis.

Normally, only a small fraction of the electrons go into generating hydrogen.

However, a major research goal has been to develop ways to increase this fraction, which would raise the potential yield of hydrogen.

In the new study, researchers at the Carnegie Institution’s Department of Plant Biology, the National Renewable Energy Laboratory (NREL), and the Colorado School of Mines (CSM), examined metabolic processes in a mutant strain that was unable to assemble an active hydrogenase enzyme.

The researchers expected the cell’s metabolism to compensate by increasing metabolite flow along other known fermentation pathways, such as those producing formate and ethanol as end products.

Instead, the algae activated a pathway leading to the production of succinate, which was previously not associated with fermentation metabolism in C. reinhardtii.

Notably, succinate, a widely used industrial chemical normally synthesized from petroleum, is included in the Department of Energy’s list of the top 12 value added chemicals from biomass.

“We actually didn’t know that this particular pathway for fermentation metabolism existed in the alga until we generated the mutant,” said Carnegie’s Arthur Grossman.

“This finding suggests that there is significant flexibility in the ways that soil-dwelling green algae can metabolize carbon under anaerobic conditions,” he added.

“By blocking and modifying some of these metabolic pathways, we may be able to augment the donation of electrons to hydrogenase under anaerobic conditions and produce elevated levels of hydrogen,” he further added.

Grossman led the effort to generate a fully sequenced Chlamydomonas genome, which has allowed researchers to identify key genes encoding proteins involved in both fermentation and hydrogen production.

Grossman feels that it is of immediate importance to generate new mutant strains to help us understand how we may be able to alter fermentation metabolism and the production of hydrogen. (ANI)

Scientists find new evidence for existence of “cold fusion”

Washington, March 24 (ANI): Scientists have across evidence for the existence of low-energy nuclear reactions (LENR), the process once called “cold fusion” that may promise a new source of energy.

Low-energy nuclear reactions could potentially provide 21st Century society a limitless and environmentally clean energy source for generating electricity, according to researchers.

“Our finding is very significant,” said study co-author and analytical chemist Pamela Mosier-Boss, of the U.S. Navy’s Space and Naval Warfare Systems Center (SPAWAR) in San Diego, California. “To our knowledge, this is the first scientific report of the production of highly energetic neutrons from an LENR device,” she added.

Fusion is the energy source of the sun and the stars.

Scientists had been striving for years to tap that power on Earth to produce electricity from an abundant fuel called deuterium that can be extracted from seawater.

Everyone thought that it would require a sophisticated new genre of nuclear reactors able to withstand temperatures of tens of millions of degrees Fahrenheit.

Martin Fleishmann and Stanley Pons, however, claimed achieving nuclear fusion at comparatively “cold” room temperatures in 1989 in a simple tabletop laboratory device termed an electrolytic cell.

But, other scientists could not reproduce their results, and the whole field of research declined.

A stalwart cadre of scientists persisted, however, seeking solid evidence that nuclear reactions can occur at low temperatures.

One of their problems involved extreme difficulty in using conventional electronic instruments to detect the small number of neutrons produced in the process.

In the new study, Mosier-Boss and colleagues inserted an electrode composed of nickel or gold wire into a solution of palladium chloride mixed with deuterium or “heavy water” in a process called co-deposition.

A single atom of deuterium contains one neutron and one proton in its nucleus.

Researchers passed electric current through the solution, causing a reaction within seconds. The scientists then used a special plastic, CR-39, to capture and track any high-energy particles that may have been emitted during reactions, including any neutrons emitted during the fusion of deuterium atoms.

At the end of the experiment, they examined the plastic with a microscope and discovered patterns of “triple tracks,” tiny-clusters of three adjacent pits that appear to split apart from a single point.

The researchers said that the track marks were made by subatomic particles released when neutrons smashed into the plastic.

Importantly, Mosier-Boss and colleagues believe that the neutrons originated in nuclear reactions, perhaps from the combining or fusing deuterium nuclei.

“People have always asked ‘Where’s the neutrons?’” Mosier-Boss said. “If you have fusion going on, then you have to have neutrons. We now have evidence that there are neutrons present in these LENR reactions,” she added. (ANI)
