Now scientists think they have a glimmer of an answer.They’ve long known that the blue tint comes from traces of boron in the diamond.(Source).Just 1 out of 200,000 diamonds is blue. The element allows the stone to absorb some red light, so the diamond looks blue."The origin of blue diamonds is such an alluring question — you don’t see them very often."You can start putting together a picture of what the surrounding rocks looked like, to recreate the birthplace of the diamonds," Smith said."It’s such an amazing stone," Tait said. "Diamond is an extraordinary container, a time capsule," said Steven Shirey, a geochemist at the Carnegie Institution for Science in Washington. "This study tells us for the first time that blue diamonds are formed very deep in the interior of Earth. As they form, they can trap tiny bits of rock inside — like fossils in amber."Diamond deposits eventually reach the surface through volcanic eruptions. Like all diamonds, they are made when carbon comes under intense pressure and extreme heat deep inside the Earth.Their findings were published Wednesday in the journal Nature.Researchers scrutinized 46 blue diamonds, studying imperfections in the gems for clues."Most of the impurities contained in these blue diamonds came from a very deep source," said Dongzhou Zhang, a scientist at the University of Hawaii, who was not involved in the research. The Hope diamond’s many owners included Marie Antoinette.The 45-carat, walnut-size Hope diamond, long rumoured to carry a curse, wasn’t included in the study but the findings help us know where it came from, said the Toronto museum’s Tait, who had no role in the research. How the light is reflected helps identify the minerals inside, said Evan Smith, a research scientist at the institute who led the study.The researchers suggest that boron in the ocean floor was pushed down when plates that make up the Earth’s crust collided.Blue diamonds — like the Smithsonian’s famous Hope diamond — are the rarest of China Customization Atmosphere Lamp manufacturer all and how they formed more than a billion years ago is a bit of a mystery. But the element is mostly found near the Earth’s surface, not deep down where diamonds are typically created.Based on their findings, it’s clear that blue diamonds are formed at far greater depths than other diamonds, some deeper than 410 miles (660 kilometres), Smith said. Most other diamonds are formed between about 90 to 125 miles (150 to 200 kilometres), Shirey said.Shirey and his colleagues used lasers to examine the diamonds’ imperfections — slivers of embedded rock — at the Gemological Institute of America. And the famous ones, like the Hope diamond, have such mystique," said Kim Tait, a gem expert at the Royal Ontario Museum in Toronto

It also adds to existing evidence that can inform upcoming physical activity guidelines over time. "We used devices to better measure not only higher intensity physical activities, but also lower intensity activities and sedentary behavior, which has become of great interest in the last few years," stated I-Min Lee, MBBS, ScD.g. For context, non-smokers have about a 50 percent reduction, compared with smokers," stated I-Min Lee, MBBS, ScD, associate epidemiologist at Brigham and Womens Hospital, and first author of the study."This is one of the first studies to investigate physical activity, and a clinical outcome, using the newer generation triaxial wearable devices which have increased sensitivity to recognize physical activity and are capable of more precise measurements than the previously used uniaxial devices, or studies relying on self-reports only.Washington: A study states that more physical activity and higher intensities of exercise could decrease the risk of death in older women from any cause.The study, led by investigators at Brigham and Womens Hospital, investigated physical activity of women measured over seven China Portable Bluetooth Audio lamp manufacturer days using a wearable device called a triaxial accelerometer. However, previous studies have primarily relied on self-reported physical activity, and self-reports tend to be imprecise."The fact the physical activity lowers mortality rate is nothing new - we have many studies showing this. Light physical activity, such as slow walking, was not associated with lower death rate during the study.Moderate to vigorous intensity physical activity (e. Based on these self-report studies, we know that physical activity is associated with a 20-30 percent reduction in mortality rates, comparing the most with the least active. Current guidelines recommend at least 150 minutes a week of moderate intensity physical activity, or 75 minutes a week of vigorous-intensity aerobic physical activity (or a combination of the two), and muscle-strengthening exercises two or more days a week."This study supports current guidelines for physical activity, such as those from the federal government and the American Heart Association, that emphasize moderate-intensity physical activity. Using device-measured physical activity in the present study, we observed a 60- 70 percent risk reduction larger than previously estimated from self-report studies..Data were analyzed from 16,741 participants (average age 72) from the Womens Health Study who wore the device for at least 10 hours a day, on at least four out of seven days. brisk walking) was associated with 60-70 percent lower risk of death at the end of the four-year study among the most active women, compared to the least active.Lack of exercise or physical activity is estimated to cause as many deaths each year as smoking. Researchers note that light activity may be beneficial for other health outcomes not reported in this paper.The findings have been published in Circulation

The researchers developed a fabrication technique that uses self-assembled nanospheres to form a precise template that can be used to create the moth-eye-like structure on a coating.Inspired by the nanostructures found on moth eyes, scientists have developed a new anti- reflection film that could allow people to read from their smartphones and tablets even in bright sunlight."In addition to exhibiting low reflection, our nature- inspired film is also scratch resistant and self-cleaning, which would protect touch screens from dust and fingerprints," said Wu, who led the study published in the journal Optica.Although this type of adaptive brightness control can help improve readability, it also drains battery power.4 per cent, for example.The new film contains tiny uniform dimples, each about 100 nanometres in diameter (about one-thousandth of the width of a human hair).23 per cent, much lower than the iPhones surface reflection of 4.The film exhibits a surface reflection of just 0. The researchers also used standard industrial procedures to test its flexibility as well as its anti-scratch and self-cleaning capabilities.When viewed in the shade, glass with the new film showed about a ten-fold improvement in contrast ratio.The coating can also be used with flexible display applications such as phones with screens that fold like a book, which are expected to hit the market as soon as next year.Many of todays smartphones use a sensor to detect bright ambient light and then boost the screens brightness level enough to overcome the strong surface reflection.Looking for a simpler approach to improve screen readability outside, the researchers turned to nature..The simplicity and precision of this process allowed fabrication of the intricate structure in a Portable Bluetooth Audio lamp film large enough to apply to a mobile screen.Tests of the film after optimisation showed that when viewed in sunlight, glass covered with the new film exhibited a more than four-fold improvement in contrast ratio – the difference between the brightest white and darkest black.The eyes of moths are covered with a pattern of antireflective nanostructures that allow moths to see in the dark and prevent eye reflections that might be seen by predators.Reflection is the major reason it is difficult to read a phone screen in bright sunlight, as the strong light reflecting off the screens surface washes out the display."Using our flexible anti-reflection film on smartphones and tablets will make the screen bright and sharp, even when viewed outside," said Shin-Tson Wu from the University of Central Florida in the US. Other methods for solving the sunlight visibility problem have proved difficult to implement

5 for females, and 6 to 0. This suggests that removal of the flowers could be a new way to shift inherently high malaria transmission areas to low transmission areas, making elimination more feasible. Villages infested with Prosopis juliflora also had a higher proportion of mosquitoes with a sugar meal in their gut, which enhances their survival.7 for male mosquitoes. After a first round of analysis was conducted to assess mosquito populations, the researchers cut all the flowering branches from Prosopis juliflora in three of the six infested villages, before setting up light traps to determine the effect removal of the shrub had on mosquito vector populations.Light traps to catch mosquitoes were set up across nine villages in the Bandiagra District, six of which were home to flowering Prosopis juliflora and three that had no presence of the shrub.The researchers found that villages where they removed the flowers saw mosquito numbers collected in the traps fall from an average of Wholesale Outdoor Umbrella Tent Lighting 11 to 4. Prosopis juliflora is a robust plant that grows rapidly and has become one of the worst invasive plants in many parts of the world. The study is published in the open access Malaria Journal. After flower removal, the number of older more dangerous vector females in the population dropped to levels similar to those recorded in the villages that had no presence of the shrub. This proportion was reduced 5-fold following removal of the flowers. Removing the flowers from villages in Mali decreased the local mosquito vector population by nearly 60%, according to the study carried out in the Bandiagra District in Mali..Washington: A new study has found that removing the flowers of an invasive shrub from mosquito-prone areas might be a simple way to help reduce malaria transmission." Muller added, "Our results show that removal of this particular shrub reduces total population levels of mosquitoes and reduces the number of older female mosquitoes in the population, which are known to transmit malaria parasites to humans."The study focused on the removal of the flowers of the invasive shrub Prosopis juliflora, which is native to Central and South America but was introduced to new areas in the late 1970s and early 1980s as an attempt to reverse deforestation. The total number of mosquitoes across these villages decreased by nearly 60% after removal of the flowers. The shrub now occupies millions of hectares on the African continent, including countries such as Mali, Chad, Niger, Ethiopia, Sudan and Kenya.According to the researchers, it may be worthwhile to abstain from the introduction of exotic plants that have the potential to become invasive, not only because of their potential negative impacts on the environment and livelihoods, but because some of them may have negative significant consequences for public health and specifically for malaria.Lead author Gunter Muller from Hebrew University Hadassah Medical School said: "Mosquitoes obtain most of their energy needs from plant sugars taken from the nectar of flowers so we wanted to test the effect removing the flowers of the shrub Prosopis juliflora would have on local mosquito vector populations
