An exotic type of diamond may have come to Earth from outer space, scientists say. Called carbonado or "black" diamonds, the mysterious stones ---1--- in Brazil and the Central African Republic. They are unusual for being the color of charcoal and full of frothy bubbles. The diamonds, which can weigh at more than 3,600 carats, can also have a face that looks like ---2--- glass. Because of their odd appearance, the diamonds are unsuitable as gemstones. But they do have industrial applications and ---3--- in the drill bits that helped dig the Panama Canal. Now a team led by Stephen Haggerty of Florida International University in Miami ---4--- a new study suggesting that the odd stones were brought to Earth by an asteroid billions of years ago. The findings were published online in the journal Astrophysical Journal Letters on December 20. The scientists exposed polished pieces of carbonado to extremely intense infrared light. The test ---5--- the presence of many hydrogen-carbon bonds, indicating that the diamonds probably formed in a hydrogen-rich environment—such as that found in space. The diamonds also showed strong similarities to tiny Nano diamonds, which are frequently found in meteorites. "They're not identical,” Haggerty said, "but they're very similar." Astrophysicists, he added, have developed theories ---6--- that Nano diamonds form easily in the titanic stellar explosions called supernovas, which scatter debris through interstellar space. The deposits in the Central African Republic and Brazil, he said, probably ---7--- from the impact of a diamond-rich asteroid billions of years ago, when South America and Africa were joined. 1) A. are found B. had found C. founded D. find 2) A. melting B. melts C. has melted D. melted 3) A. are used B. use C. have been used D. were used 4) A. had presented B. has presented C. to present D. presented 5) A. reveals B. is revealed C. revealed D. revealing 6) A. predicting B. have predicted C. been predicted D. predict 7) A. have come B. had come C. come D. comes #RWFIB #636_Black_Diamonds

Rather than cringing at the next beetle or wasp in your way, you might want to thank them for helping ---1--- city streets clean. Researchers from North Carolina State University ---2--- in New York City found that hungry urban arthropods play a significant role in the disposal of trash. For example, in a small section of Manhattan called the Broadway/West Street corridor, insects ---3--- the equivalent of 60,000 hot dogs a year that would otherwise be lying in the street. And that's assuming the bugs stop chowing down in winter. To assess how much discarded food bugs got rid of, the researchers ---4--- measured amounts of hot dogs, potato chips and cookies at 21 park sites and 24 street medians. Contrary to their prediction, location played an even bigger role in garbage consumption than biodiversity did--insects gobbled up two to three times more food in the street medians than they did in the parks. The study ---5--- in the journal Global Change Biology. If all that garbage disposal still does not make you an arthropod admirer, then consider this: by ---6--- with larger pests for resources, insects help keep rat populations down.

Conscientiousness is a fundamental personality trait. A conscientious person is good at self-regulation and impulse control. This trait influences whether you will set and keep long-range goals, deliberate over choices, behave cautiously or impulsively, and take obligations to others seriously. #RA #577_Conscientiousness

A new study projecting the economic futures of countries over the next century finds growth will be slower than predicted, with developing countries taking longer to close the wealth gap and approach the income of wealthier nations. What economists have thought of as a worst-case scenario for global economic growth may be a best-case scenario, according to the new study published in Communications Earth and Environment. #ra #read_aloud

1.The Brundtland Report, our Common Future (1987) defines sustainable development as 'development which meets the needs of the present without compromising the ability of future generations to meet their own needs'. 2.Development in the past was driven by growth and innovation. It led to new technologies and huge improvements in living standards. 3.Implicit in this definition is the idea that the old pattern of development could not be sustained. Is this true? 4.Whatever happened to the idea of progress and a better future? I still believe both. 5.To assume that we know what the circumstances or needs of future generations will be is mistaken and inevitably leads to the debilitating sense that we are living on borrowed time. #Ro_134 #Apeuni_prediction ——————————————————— 🎖Together we persevere, Together we can 🎖 @Iran_pte_house

1.Bananas also contain tryptophan, which the body converts to serotonin, helping to improve mood. They are an excellent source of potassium, which is vital for heart health and blood pressure regulation. 3.However, people with certain medical conditions, such as kidney disease, need to be cautious about their banana intake due to high tryptophan levels. 4.In terms of nutrition, bananas are highly beneficial. #Ro_742 #Apeuni_prediction ——————————————————— 🎖Together we persevere, Together we can 🎖 @Iran_pte_house

1. In this last collision, one embryo was nearly Earth-sized and the other approximately Mars-sized. 2.According to the giant impact hypothesis, our moon formed as the result of the last of a series of "giant impact" mergers between planetary embryos that eventually formed the Earthnswer 3.For more than 30 years, the prevailing view of the formation of our moon has been the "giant impact hypothesis". 4.The precursors to the current four rock planets – Mercury, Venus, Earth and Mars – appear to have been dozens of smaller bodies known as "planetary embryos". #Ro_176 #Apeuni_prediction ——————————————————— 🎖Together we persevere, Together we can 🎖 @Iran_pte_house

1. But with opportunity comes responsibility! 2.That means it's up to you to carve out your place in the world and know when to change course 3. Companies today aren't managing their knowledge of workers' careers. 4.We live in an age of unprecedented opportunity: with ambition, drive, and talent, you can rise to the top of your chosen profession regardless of where you started out. 5. Instead, you must be your own chief executive officer. #Ro_192 #Apeuni_prediction ——————————————————— 🎖Together we persevere, Together we can 🎖 @Iran_pte_house
