Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.

    Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting（收缩）and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.

    Sarah Garfinkel at the Brighton and Sussex Medical School said: “Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”

    The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, “The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see and guide whether we see fear.”

    To further understand this relationship, the scientists also used a brain scanner（扫描仪）to show how the brain influences the way the heart changes a person's feeling of fear.

    “We have found an important mechanism by which the heart and brain ‘speak' to each other to change our feelings and reduce fear,” Dr Garfinkel said.

    “We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those who may be suffering from serious stress disorder.”

It's long been thought that in order to succeed in life you need to think only of yourself and ignore the needs of others. New research,however,suggests the exact opposite is true and being nice to others actually makes you more likely to be successful. The scientists found that ‘givers' were more likely to share knowledge,and in turn gain more information themselves.

    Researchers divided participants into three groups based on a personality test: givers, takers and matchers. In a social dilemma task, participants were given a made-up donation which was equal to the amount of ￡ 240( $400). They were then asked to decide how much of their money they would give to a shared group pool. They were told that the money in the pool would be doubled and divided equally among all group members. Thus,it would be more beneficial to the group as a whole if everyone contributed their individual donations. However, it would be more beneficial for the individual if everyone else from the group contributed,while the individual kept his or her own money. The researchers used this strategic (策略的) information sharing task to examine how much and which pieces of information participants shared:the less important and already known information or the really important information only known by the individual.

    The results showed that givers are less self-centered and self-loving than takers. Givers shared not only more money with the group, but they also shared important information. Takers on the other hand kept both the money as well as different types of information.

    The findings suggest that it may not be enough to simply provide knowledge management tools in order to make the best of knowledge exchange in a group of people. It may be necessary for leaders and managers to keep in mind the personality styles of their employees. Specifically, they should be aware that takers may keep the important information for themselves.

    Bandhavgarh National Park in India is best known for its amazing setting, as well as having the highest concentration of tigers in India. In addition to tigers, there are also bears, deer, wolves, birds, etc.

    Location: In Madhya Pradesh state, almost 200 kilometers northeast of Jabalpur. The nearest village is Tala, which is the access point of the park.

    Opening Hours and Safari (游猎) Times

    Safaris operate twice a day, starting at dawn until late morning, and mid afternoon until sunset. The best time to visit the park is early in the morning or after 7 p.m. to spot the animals. The park is closed from July 1 to September 30 due to the monsoon season (季风季节).

    Bandhavgarh Zones

    Bandhavgarh is divided into three main zones: Tala (the park's best zone, with the most tigers), Magdhi (the second best zone to see tigers), and Khitauli (scenic and less visited, although tiger sightings do occur there; particularly good for birding).

    Entry Fees and Charges for Jeep Safaris

    Bandhavgarh has become expensive to visit in recent years. Entry fees have increased since October 2014. When going on a safari, separate fees must be paid for park entry and jeep hire. Entry tickets are priced per vehicle (up to six people). For 2015-16, park entry tickets cost as follows:

    ·Tala Zone: 2,400 rupees for Indians, 4,800 rupees for foreigners. (Up to six people)

    ·Other Zones: 1,200 rupees for Indians, 2,400 rupees for foreigners. (Up to six people)

Jeep Hire

    Expect to pay about 2,200 rupees to hire a jeep, in addition to the entry cost. This can be done at the park entrance. All hotels can arrange jeep hire and tours, but at a higher rate. It's much less trouble though. Besides, unlike many national parks in India, it's possible to take private vehicles into Bandhavgarh.

Channel Islands

The two main islands, Jersey and Guernsey, are remarkable in that they present a combination of enjoyment peace and quiet. Neither island is very big (only ten miles long) and so all parts of these coasts are easily reached from the main centers — St. Helier and St. Peter Port. In both these towns and particularly in Jersey's St. Helier are concentrated (集中) the amusements of really big resorts (休养地). The nearness of France gives a continental atmosphere; the weather is far better than that in England. The other three islands, Jethou, Herm and Sark are small and quiet.

Isles of Scilly

The islands are really small and quiet; and the weather is warm but windy. The islands are excellent for those who enjoy exploring (探险) small inlets (水湾), creeks (小溪) and bays on foot, or even better in a boat.

Isle of Wight

The island is 24 miles across and therefore quite large. The scenery is good and varied. The resorts are neither overlarge nor showy. The crowds seem content with entertaining but quieter holidays. The island has the best sunshine record in Britain.

Isle of Man

An island with unique atmosphere — in some indefinable (难以描述的) way it is different from England, Scotland or Wales. Thirty miles long, with good roads and good public transport, the mountains, hills and glens (幽谷) are easily reached. Douglas is a major British resort and other resorts are lively.

Researchers say they've used cutting-edge gravitational wave research to cast new light on a mystery—a 2000-year-old computer,the Antikythera mechanism found in shipwreck. 

Well over a century after its discovery,researchers at the University of Glasgow say they've used statistical modeling techniques,originally designed to analyze gravitational waves —ripples in spacetime caused by major events in the universe such as two black holes combining —to suggest that the Antikythera mechanism was likely used to track the Greek lunar year. In short,it's a fascinating collision between modern-day science and the mysteries of an ancient artifact. 

In a 2021 paper,researchers found that previously discovered and regularly spaced holes in a "calendar ring"were marked to describe the "motions of the sun,moon,and all five planets known in ancient Greeks and how they were displayed at the front as an ancient Greek universe. "Now,in a new study published in the Official Journal of the British Horological Institute,University of Glasgow gravitational wave researcher Graham Woan and research associate Joseph Bayley suggest that the ring was likely perforated (打孔)with 354 holes, which happens to be the number of days in a lunar year. 

The team used statistical models derived from gravitational wave research,a large-scale physics experiment designed to measure ripples in spacetime millions of light-years from Earth and Bayesian analysis,a technique using probability to quantify uncertainty based on incomplete data,to calculate the likely number of holes in the mechanism using the positions of the surviving holes and the placement of the ring's surviving six fragments. 

Surprisingly,the inspiration for the study came from a YouTuber Chris Budiselic,who has been attempting to physically recreate the ancient mechanism and investigating ways to determine just how many holes it contained. 

"It's a neat symmetry that we've adapted techniques we use to study the universe today to understand more about a mechanism that helped people keep track of the heavens nearly two millennia ago,"Woan said. 

"We hope that our findings about the Antikythera mechanism,although less supernaturally spectacular than those made by Indiana Jones,will help deepen our understanding of how this remarkable device was made and used by the Greeks,"Woan sadded.
