    We all know what a brain is. A doctor will tell you that the brain is the organ of the body in the head. It controls our body's functions, movements, emotions and thoughts. But a brain can mean so much more.

    A brain can also simply be a smart person. If a person is called brainy, he is smart and intelligent. If a family has many children but one of them is super smart, you could say, “He's the brains in the family.” And if you are the brains behind something, you are responsible for developing or organizing something. For example, Bill Gates is the brains behind Microsoft.

    Brain trust is a group of experts who give advice. Word experts say the phrase “brain trust” became popular when Franklin D. Roosevelt first ran for president in 1932. Several professors gave him advice on social and political issues（问题）facing the U.S. These professors were called his “brain trust”.

    These ways we use the word “brain” all make sense. But other ways we use the word are not so easy to understand. For example, to understand the next brain expression, you first need to know the word “drain”. As a verb, to drain means to remove something by letting it flew away. So a brain drain may sound like a disease where the brain flows out the ears. But, brain drain is when a country's most educated people leave their countries to live in another. The brains are, sort of, draining out of the country.

    However, if people are responsible for a great idea, you could say they brainstormed it. Here, brainstorm is not an act of weather. It is a process of thinking creatively about a complex topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.

    If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to make some accept new beliefs by using repeated pressure in a forceful or tricky way. Keep in mind that brainwash is never used in a positive way.

    Scientists have always been interested in the high level of organization in ant societies. American researchers have watched ants build life-saving rafts to keep afloat during floods. They also have recorded how ants choose their next queen — the female whose job is to produce eggs.

    New technology is helping to improve researchers' understanding of the insects. But there is still a lot to be learned.

    Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common. To save themselves, the insects connect their legs together and create floating rafts. Some ant rafts can be up to 20 centimeters wide.

    David Hu is an engineer with the Georgia Institute of Technology, also known as Georgia Tech, saying, "If you have 100 ants, which means 600 legs, 99 percent of those legs will be connected to a neighbor. So they're very, very good at keeping this network. "

    David Hu and other Georgia Tech researchers wanted to study ants and the secret of their engineering. They froze ant rafts and then looked at them with the help of computed technology, or CT images. The pictures showed that larger ants serve in central positions to which smaller ants hold. The larger ants create pockets of air that keep the insects afloat.

    Scientists say small robots or materials that can change shape could be programmed in a similar way, working towards a shared goal.

    Researchers at North Carolina State University are also studying ants. They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen.

    You may have heard the term self-awareness, but what is it and why does it matter?

    Being self-aware can influence how you feel in your job and in your personal life. Daniel Goleman takes that connection much further, saying self-awareness is the key to success. He describes self-awareness as “knowing one's internal（内在的）states ,preference and resources”, and then monitoring that “inner world” information as it comes up. If you can be as aware of your feelings and thoughts, you'll be better able to deal with new situations. Because you know yourself better, you'll be more accepting of yourself, your thoughts and your feelings, Goleman says.

    But self-awareness doesn't stop at how you see yourself. It's also understanding and acknowledging how others see you. Tasha Eurich, an organizational psychologist, explains that self-awareness has two parts — internal and external（外部的）. Internal self-awareness means we can clearly see our own values, thoughts, passions and feelings. External self-awareness is clearly seeing how others see us. People who are externally self-aware tend to be better leaders.

    So how do you know if you're self-aware or not? Eurich developed a short online quiz to help. You're not the only one who has to take it. Someone who knows you well also has to answer questions about you.

    In a recent TED Talk, Eurich refers to self-awareness unicorns. This group makes up only a small part of all the people she has studied. These are people who not only believe they are self-aware, but other people who know them would agree. Additionally, these unicorns would say they have improved their self-awareness in their lives and again, those who know them well would agree.

    Thankfully, anyone can become more self-aware, as long as they're willing to devote some time and effort to the cause.

Tests have shown robots can diagnose heart problems in as little as four seconds, as a review of artificial intelligence (AI) finds machines are now as good at spotting illness as doctors.

Analyzing a patient's heart function on a cardiac MRI (心脏磁共振成像) scan currently takes doctors around 13 minutes. But a new trial by University College London (UCL) showed an AI program could read the scans in less time with equal accuracy. There are approximately 150,000 such scans performed in the UK each year, and researchers estimate that fully using AI to read them could save 54 clinician-days (临床天数) at each cardiac centre per year. So it can make up for the shortage of doctors.

It is hoped that AI where computer systems are able to learn from data to identify new patterns with minimal human intervention will transform medicine by helping doctors spot diseases such as heart disease and cancer faster and earlier. However, most scans are still read by specially trained doctors.

Dr Charlotte Manisty, who led the UCL research, said, "Cardiovascular MRI offers in- comparable image quality for assessing heart structure and function. However, current manual analysis remains basic and outdated. Automated machine techniques offer the potential to change this and completely improve efficiency and accuracy, and we look forward to further research that could confirm the superiority to human analysis."

She added, "Our dataset of patients with a range of heart disease who received scans enabled us to demonstrate that the greatest sources of measurement errors arise from human factors. This indicates that automated techniques are at least as good as humans, with the potential soon to be 'super-human'—transforming clinical and research measurement precision."

Professor Alastair Denniston said, "Within those handful of high-quality studies, we found that by deep learning AI could indeed detect disease ranging from cancer to eye disease as accurately as health professionals. But it's important to note that it did not absolutely exceed human professional diagnosis. "

Cala didn't like us. Any of us. We didn't do anything to offend her and she didn't know us but that didn't matter; she still didn't like us.

As new teachers in the Emirati school, we Westerners greeted her every day. She ignored us. She came into our rooms and bypassed us as she shook hands with all the non-Westerners. Whenever we saw her, she avoided eye contact with us. Eventually, we stopped trying to befriend her.

I wouldn't say her nationality but her friends had been fired from the school. We had been employed in their places and that was enough for her to have nothing to do with us.

Well after 16 months in the school we had a secret friend gifting. To my surprise, I drew her name from the glass jar and that meant she was my secret friend. My role was to buy her a gift and say something about her when we publicly acknowledged who our secret friend was.

I decided to gift her a coloured bangle (手镯). I added a postcard and wrote "Love and Blessings, Rose Marie.

Then came the day. We all gathered in the meeting room. When you gave your gift, you said a few kind words about your secret friend and passed the gift to her. What could I say? Everyone knew she didn't like the Westerners. She taught music in the school so I said "My secret friend is someone who brings music to our ears every day." She came forward with a huge warm smile. She hugged me and kissed me on both cheeks and accepted my gift.

Since then, she smiles often. We hug and shake hands when we meet. I have seen her wear my gift several times and I am so pleased.
