- Usually, age is determined by physical characteristics, such as teeth or bones. Great—if you have a body. Researchers have tried unsuccessfully to use blood. But in this study, the scientists used immune cells called T-cells. T-cells recognize invaders through receptors that match molecules on bacteria, viruses, and even tumours. The cellular activity that produces these receptors also produces a type of circular DNA molecule as a by-product.
- The caterpillars that feed on trees are trying to match the hatching of their eggs to the timing of the budburst. The caterpillars want to feed on the juiciest and least chemically protected leaves. And it’s not just the caterpillars, of course, that are important. But the knock-on effect is on nesting birds, which are also trying to hatch their chicks at the same time that there’s the maximum number of caterpillars.
- As to the Industrial Revolution, one cannot dispute today the fact that it has succeeded in inaugurating in a number of countries a level of mass prosperity which was undreamt of in the days preceding the Industrial Revolution. But, on the immediate impact of the Industrial Revolution, there were substantial divergences among writers.
- A marketing plan is a comprehensive document or blueprint that outlines a business’s advertising and marketing efforts for the coming year. It describes business activities involved in accomplishing specific marketing objectives within a set time frame. A marketing plan also includes a description of the current marketing position of a business.
- The Japanese tea ceremony is a ritual tour influenced by Buddhism in which green tea is prepared and served to a small group of guests in a peaceful setting. The ceremony can take as long as four hours and there are many traditional gestures that both the server and the guest must perform.
- Australians do speak English; however, for some tourists and travelers, it can be difficult to understand the slang. Also, the links between Australian and American English were seen to be tenuous. At least some colloquialisms in Australian English do not exist in other types of English
- The co-evolutionary relationship between cows and grass is one of nature’s underappreciated wonders; it also happens to be the key to understanding just about everything about modern meat. For the grasses, which have evolved to withstand the grazing of ruminants, the cow maintains and expands their habitat by preventing trees and shrubs from gaining a foothold and hogging the sunlight; the animal also spreads grass seed, plants it with his hooves, and then fertilizes it with his manure.
- Environmental problems caused by hard rock mining involve water pollution by metals themselves, chemicals used in processing, acid drainage, and sediment. Metals and metal-like elements in the ore are toxic and prone to cause trouble by ending up in nearby streams and water tables as a result of mining operations.
- What we found is that the plant is actually damaged by herbivores like most plants are in nature. And in response to that it secretes sugar from the wound edges where the herbivores have damaged the plant. ”Tobias Lortzing is a graduate student at Freie University Berlin and one of the study authors.
- The border itself between Mexico and the United States is fraught with a mix of urban and desert terrain and spans over 1,900 miles. Both the uninhabited areas of the border and urban areas are where the most drug trafficking and illegal crossings take place. Crime is prevalent in urban cities like El Paso, Texas, and San Diego, California.
- While the Republican field is packed with male candidates, so far, some of the sharpest Clinton critics have come from women. Democrats successfully campaigned on an alleged GOP-perpetrated “war on women” in 2012 but faltered in 2014 when they tried the same tactic. With Hillary Clinton as the likely Democratic nominee, the fight for women voters will be a central part of the 2016 campaign.
- Trump has threatened to declare China a currency manipulator, but experts say he has little legal or economic basis to take such a step. He has also threatened to impose a tariff of up to 45 percent on Chinese imports if Beijing doesn’t “behave” a move that could lead to a trade war and damage the economies of both nations.
- Since Plato, philosophers have described the decision-making process as either rational or emotional: we carefully deliberate or we ‘blink’ and go with our gut. But as scientists break open the mind’s black box with the latest tools of neuroscience, they’re discovering that this is not how the mind works. Our best decisions are a finely tuned blend of both feeling and reason—and the precise mix depends on the situation.
- Before European explorers had reached Australia, it was believed that all swans were white. Dutch mariner, Antonie Caen, was the first to be amazed at the sight of Australia’s Black swans on the Shark Bay in 1636. Explorer Willem de Vlamingh captured two of these creatures on Australia’s Swan River and returned with them to Europe to prove their existence. From that point on, black swans and Australia have been closely linked.
- The grid-based infrastructure enables large-scale scientific applications to be run on distributed resources and coupled in innovative ways. However, in practice, grid resources are not very easy to use for the end-users who have to learn how to generate security credentials. There is an imminent need to provide transparent access to these resources so that the end-users are shielded from the complicated details.
- Electronic discourse is one form of interactive electronic communication. In this study, we reserve the term for the two-directional texts in which one person using a keyboard writes language that appears on the sender’s monitor and is transmitted to the monitor of a recipient, who responds by the keyboard.
- Long isolated from Western Europe, Russia grew up without participating in development like the Reformation which many Europeans taking pride in their unique culture, find dubious value. Russia is, as a result, the most unusual member of the European family, if indeed it is European at all. The question is still open to debate, particularly among Russians themselves.
- The Grand Canyon is 277 miles long, up to 18 miles wide, and attains a depth of over a mile. While the specific geologic processes and timing that formed the Grand Canyon are the subject of debate by geologists, recent evidence suggests the Colorado River established its course through the canyon at least 17 million years ago.
- Scientists know little about how exactly it works, especially when it comes to complex functions like memory formation. Research is more advanced in animals, but experiments on humans are hard. Yet, even today, some parts of the brain, like the motor cortex, are better understood. Nor is complete knowledge always needed. Machine learning can recognize patterns of neural activity; the brain itself gets the hang of controlling BCIS with extraordinary ease. And neurotechnology will reveal more of the brain’s secrets.
- Tesla actually worked for Edison early in his career. Edison offered to pay him the modern equivalent of a million dollars to fix the problems he was having with his DC generators and motors. Tesla fixed Edison‘s machines and when he asked for the money he was promised, Edison laughed him off and had this to say, “Tesla, you don‘t understand our American humour.”
- Marriage is a big step in anyone’s life and there is an argument to be made against getting married too early. As any newlywed couple knows, there is a huge amount of financial pressure associated with marriage. Firstly, the wedding reception and honeymoon will cost you an arm and a leg. Then there’s the matter of home loans, rent, and energy bills. If you’re looking to start a family, your child’s education is another thing you need to save up for. Teenagers should probably find a proper job before deciding to tie the knot.
