first_img Explore further Cold fusion, is of course, a theoretical means of harnessing enormous amounts of energy by fusing atoms together. Normal fusion is what powers the sun, but it of course, is very hot. Scientists have been working for years to come up with a way to cause fusion to come about in a way that doesn’t require a huge amount of heat—thus the name cold fusion. Unfortunately, to date, no one has been able to figure out a way to do it—no one but Rossi, that is, if his claims turn out to be true.Rumors of how ECAT’s plant works suggest it’s little more than a simple tube that utilizes an unknown nano-sized nickel type catalyst. When hydrogen is added, heat and perhaps copper, is produced. According to ECAT, the plant does nothing more than produce heated water and/or steam. Those that purchase the plant are free to attach it to a turbine to create electricity. The plant is small—just 20x20x1 centimeters, but each unit can be stacked. The company has put 106 of the units in a shipping container and all together they make up the ECAT 1MW Plant, selling for a cost of $1.5 million to anyone that wants and can afford one.Read more: Controversial energy-generating system lacking credibility: phys.org/news/2011-08-controversial-energy-generating-lacking-credibility-video.htmlRossi’s E-Cat gets first customers, but questions remain: phys.org/news/2011-11-rossi-e-cat-customers.htmlTests find Rossi’s E-Cat has an energy density at least 10 times higher than any conventional energy source: phys.org/news/2013-05-rossi-e- … -density-higher.html There have been various sightings of ECAT’s technology, in 2011 for example, a select group of scientists was invited to witness a prototype in action. Reports from the demonstration suggest the prototype was able to generate 470 kw before a system fault caused the test to be stopped. That was enough apparently, for DARPA, which has reportedly already preordered one of the plants.The portable plants are expected to be ready for delivery in approximately four months, which should end the mystery. If Rossi has succeeded where so many others have failed, he and his colleagues will be cheered and likely awarded a Nobel Prize. If the debut is a flop, however, it will be more than just an embarrassment to him and his company, it will be a very sad day for science and perhaps another indication that cold fusion, simply cannot be done.

Founded by Italian scientist Andrea Rossi, the plant has the scientific community shaking its collective head—it’s never been peer reviewed and neither Rossi nor anyone else at ECAT has ever published a single paper regarding cold fusion or describing how the plant works.center_img © 2013 Phys.org Rossi’s E-Cat gets first customers, but questions remain Credit: ECATlast_img read more


first_imgA small team of researchers with the Vienna Biocenter has discovered that a protein that exists on the exterior of zebrafish eggs acts as a sentry—allowing only sperm from zebrafish to enter. In their paper published in the journal Science, the group describes discovering the protein and the way they tested its purpose. Ruth Lehmann with the NYU School of Medicine writes a Perspective piece on the work done by the team in the same journal issue. Journal information: Science This document is subject to copyright.

DOI: 10.1126/science.aat7113AbstractFertilization is fundamental for sexual reproduction, yet its molecular mechanisms are poorly understood. We found that an oocyte-expressed Ly6/uPAR protein, which we call Bouncer, is a crucial fertilization factor in zebrafish. Membrane-bound Bouncer mediates sperm-egg binding and is thus essential for sperm entry into the egg. Remarkably, Bouncer not only is required for sperm-egg interaction but is also sufficient to allow cross-species fertilization between zebrafish and medaka, two fish species that diverged more than 200 million years ago. Our study thus identifies Bouncer as a key determinant of species-specific fertilization in fish. Bouncer’s closest homolog in tetrapods, SPACA4, is restricted to the male germline in internally fertilizing vertebrates, which suggests that our findings in fish have relevance to human biology. Infertility mechanism in males identified Citation: Protein in zebrafish found to keep out sperm of other fish (2018, September 7) retrieved 18 August 2019 from https://phys.org/news/2018-09-protein-zebrafish-sperm-fish.html © 2018 Phys.org For fish like the zebrafish, it is important to protect eggs from fertilization by other fish species—this is because they lay their eggs in the water. The eggs are subsequently fertilized by sperm that males eject into the water. The researchers in this new effort have found the mechanism involved—the fish produce a protein that serves as a gatekeeper, allowing only zebrafish sperm to enter.The researchers discovered the protein as they were conducting a study of the zebrafish genome—they found a gene responsible for producing a previously unknown 80 amino acid protein. Because of its location in the genome, the researchers suspected it was involved in reproduction. The discovery led them to design and carry out experiments to determine its purpose.The researchers used CRISPR to engineer test zebrafish that produce a homolog of a protein from another fish species—medaka. This allowed medaka sperm to fertilize eggs from the test zebrafish, but blocked the zebrafish sperm. This established that the purpose of the protein was to serve a gatekeeper, which is why they named it Bouncer.The results are important, Lehmann notes, because they bring scientists closer to understanding species-specific fertilization. She further notes that despite efforts by researchers over the years, the mechanism by which an egg and sperm produce a zygote is still not very well understood. Therefore, any new piece of information is important. The researchers plan to continue their study of Bouncer, with a specific goal of determining the bonding factors that come into play between egg and sperm.last_img read more

first_imgAccording to researchers, a woman’s choice to fit in with a crowd or stand out may depend on the size of her high heels which explains the deep human urge to gain status in the society.The findings showed that women adopt local trends like changing the size of heels while moving to richer parts of the city but ignore them when they move to socio-economically lower areas.“In other words, most women want to look like rich girls and different from the poor girls,” said Kurt Gray, assistant professor at University of North Carolina in the US. Also Read – ‘Playing Jojo was emotionally exhausting’While moving to posh cities, women tend to closely try and match the size of their heels with the heel size of other women in that city, showing a deep desire for conformity. However, on the contrary, in a bid to keep up with their individuality, they match the size of their heels with the size of their own past purchases, when shifting to poorer localities.The researchers labelled this phenomenon as “trickle down conformity”, because fashion preferences trickle down from the top but seldom up from the bottom.  Also Read – Leslie doing new comedy special with Netflix“From the beginning of time, people have thirsted for respect and social standing, and have aligned themselves with the powerful and distanced themselves from the powerless. So it makes sense that they do the same with heel sizes,” Gray explained in the paper published in the journal PLOS ONE. This “aspirational fashion” of people want to look rich is getting more prevalent, with the increasing inequality in society and widening gap between rich and poor.  To examine this trend, the researchers teamed up with a large-online fashion retailer. They examined the size of high heels in five years of shoe purchases —16,236 in total _of 2007 women who moved between one of 180 US cities. Such aspirations also fuel the fortunes of fashion sites that provide high-status goods for low prices, the researchers noted, adding that the phenomenon may also apply to men. “Men do the same thing when they purchase clothes, electronics or cars,” Gray said.last_img read more


first_imgKOLKATA: Dunlop flyover, which remained closed for light motor vehicles since the collapse of a height bar on early Saturday morning, has been thrown open to small cars from Sunday morning after the repair work was done on a war footing.It is assumed that the height bar collapsed after it was hit by a truck on Saturday morning. The incident caused traffic congestion in the area for a few hours. Senior officials of the state government, engineers from various departments and police personnel carried out the repair works throughout the day on Saturday and it was erected early on Sunday morning. Also Read – Rain batters Kolkata, cripples normal lifeThe vehicles were allowed to ply from Sunday. The Barrackpore police have decided to conduct stringent vigil to ensure that no goods vehicles enter the flyover. There was major traffic congestion in the area on Saturday following the incident. The traffic movement was diverted through BT Road after the vehicles on their way from Dakshineswar were caught in traffic snarl. There was congestion on BT Road as well because of the diversion. The top cops of Barrackpore police were out on the streets till late Saturday night managing traffic. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAccording to a senior police officer at Barrackpore Police Commissionerate, the normalcy was restored since early Sunday morning when the fly over was thrown open to light vehicles. The busy flyover had been closed for all types of vehicles for the past one-and a-half-month, following the Majerhat bridge incident. The height bar was constructed to restrict the movement of some vehicles and some repair works were also carried out. It was later opened for small vehicles. It may be mentioned here that Dunlop flyover was mentioned on the list of bridges prepared by the state government whose health condition was not up to the mark. After the Majerhat mishap, various government agencies carried out examination in order to check the health conditions of some bridges and flyovers in the city and also in the districts. Bengal government has taken up preventive measures to check the occurrence of a similar incident that occurred in Majerhat on September 4. A portion of the Majerhat Bridge caved in leading to the death of three persons. It may be recalled that some representatives from the RITES had submitted a report to the state government saying that the condition of bearings situated on the top of the pillars were not in stable and some repair works needed to be done. Police are conducting a probe to ascertain the exact cause of the collapse of the height bar. Preliminary investigation suggests that a heavy duty vehicle might have hit the height bar and it eventually collapsed.last_img read more

In the name of law violation programme what the BJP and its cadres are doing is just hooliganism,” he told newsmen. His comments come against the backdrop of BJP’s “law violation” programme in various parts of the state against the state government’s decision to deny it permission to hold the Rath Yatra programmes in the state. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed “The sole aim of BJP’s Rath Yatras was to incite communal passion in the state,” he said. Several BJP workers and police personnel were injured after a “law violation” programme of the saffron party turned violent in Basirhat town in North 24 Parganas district on Monday. At least 54 people have been arrested or detained in this connection, police said. The Supreme Court had on Monday declined urgent hearing on a BJP plea challenging a Calcutta High Court order disallowing its Rath Yatras in the state. The three-phased Rath yatra, also being called the ‘Save Democracy Rally’, was scheduled to be held this month and cover all the 42 Lok Sabha constituencies. The rallies were to be flagged off by BJP president Amit Shah.last_img read more


first_imgKolkata: After Mishti Hub, Muslin Hub and similar other clusters, the state government is likely to lay the foundation stone for the construction of the long-proposed ‘lighting hub’ in Chandannagar on February 22.Speaking to the Press on the sidelines of a seminar organised by the Merchants’ Chamber of Commerce and Industry on Tuesday, the minister of Technical Education, Training and Skill Development Purnendu Basu said: “Chandannagar is famous for its lighting displays worldwide. But the workers who are involved in this segment have training of the traditional kind and they learn the craft by observing others. Unfortunately, the number of these workers is plummeting.” Also Read – Bose & Gandhi: More similar than apart, says Sugata Bose”The foundation stone of the lighting hub is most likely to be laid on February 22, when Chief Minister Mamata Banerjee will visit the Hooghly district. The government has sanctioned Rs 12 crore for the project and the site of the project has also been decided,” he added. Last year, the Bengal government had announced funding for the proposed lighting hub, to give a structured boost to the industry by creating a special zone. Basu further said: “Apart from the lighting hub, the state government has also decided to open an institute in the area. This will be an industrial training institute (ITI) which will train people in electrical work, wiring and use of digital medium, helping the workers learn the craft better. Teachers who want to provide training in this institute are welcome to come and teach these workers.” Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataSpeaking at a seminar on ‘Way forward to skill Bengal: Reforms, Challenges and Imperatives’, Basu also said that India faces a serious shortage of skilled workers and only about 2 percent of workers have received skill training. A large section of the workforce lack skills and are hence unemployable. There is a need to identify the skill gap and bridge the gap with help from experts. Apart from the West Bengal Skill Development Mission, the Bengal government had also launched the flagship scheme of ‘Utkarsh Bangla’ in 2016, to deliver skill development training and to create an industry-ready workforce. Capacity building is taking place through the programme, which aims to train at least 6 lakh youths annually. The portal has been a success and it has allowed convergence of different stakeholders. The government is providing training at ITIs, as well as other institutions including private-public partnerships, he maintained.last_img read more


first_imgRedoing your office interiors? Try out some of the must-have elements in office spaces like the right furniture, adding nature to the surroundings and activity-based settings. Below, experts have recommended a few things to keep in mind if you are going for a change:The right furniture: This plays a pivotal role in any kind of workspace setting. Offices need to invest in the right kind of furniture to increase their employees’ efficiency. Opt for something that has high functionality over ordinary designs. Adjustable desks and chairs can be a good choice; multipurpose furniture can also be added to save space. Another new entrant in the space is reconfigurable furniture that can be customized as per need. It provides both the required flexibility as well as privacy. Also Read – Add new books to your shelfGo back to nature: Add in a little nature to your premises with biophilic designs. The latest trend in the office space, the presence of plants and other natural elements can add positivity to the environment and improve the air quality.Activity-based settings: It is exciting to be at a workplace that engages you with a diverse group of people and gives you the opportunity to network and collaborate. Flexible workstations, new age cabins, activity-based settings including comfortable couches and beanbags, breakout zones, meeting lounges and pods are some of the attractions in an office that provide a natural crossroad for employees to meet and share ideas, thereby enhancing their motivation levels and productivity. Also Read – Over 2 hours screen time daily will make your kids impulsiveErgonomic lighting: Our cortisol level drops significantly under artificial and poor lighting conditions and dimly lit workplaces strain the eyes, causing headache and drowsiness. This can lead to poor productivity. Natural light is the best. Daylight that filters through space not only affects employee well-being but also boosts the energy and mood level. Consider making the best use of natural light and swap the fluorescent bulbs with personal lamps, string lighting, and soft coloured bulbs to keep your employees alert and attentive. Aesthetic appeal: Everything from layout to furniture and even artwork is subject to appeal in a workplace. The idea is to create a transcendental experience for the user and to design a warm casual space that works as an incubator for ideas. Materials like wood and metal bring warmth and rustic feel to space. Keeping in mind the fact that the office workspaces today are dynamic in nature and are witnessing rapid changes, the workplace style should be bold, industrial and vibrant with new age materials, technology and decluttered design vocabulary.Technology: A modern office space is incomplete without the right technology. Integrated systems, fast-speed internet connections and latest hardware and software are things your office must have to appeal to the incoming tech-savvy generations. Not only that, an office can also invest in mobile devices or rather agile settings to help one switch easily from one place as to another. The new workforce prefers more flexibility which will, in turn, result in enhanced productivity.last_img read more
