Is climate change consuming your favorite foods?

    Coffee: Whether or not you try to limit yourself to one cup of coffee a day, the effects of climate change on the world's coffee-growing regions may leave you little choice. {#blank#}1{#/blank#} America, Africa, Asia and Hawaii are all being threatened by rising air temperatures and unstable rainfall patterns, which invite disease and {#blank#}2{#/blank#} species to live on the coffee plant and ripening beans. The result? Significant cuts in coffee yield and less coffee in your cup. It is estimated that, if current climate patterns continue, half of the areas {#blank#}3{#/blank#} suitable for coffee production won't be by the year 2050.

    Tea: When it comes to tea, warmer climates and erratic precipitation aren't only {#blank#}4{#/blank#} the world's tea-growing regions, they're also messing with its distinct flavor. For example, in India, researchers have already discovered that the Indian Monsoon has brought more intense rainfall, making tea flavor weaker. Recent research coming out of the University of Southampton suggests that tea-producing areas in some places, {#blank#}5{#/blank#} East Africa, could decline by as much as 55 percent by 2050 as precipitation and temperatures change. Tea pickers are also feeling the {#blank#}6{#/blank#} of climate change. During harvest season, increased air temperatures are creating an increased risk of heatstroke for field workers.

    Seafood: Climate change is affecting the world's aquaculture as much as its agriculture. As air temperatures rise, oceans and waterways absorb some of the heat and {#blank#}7{#/blank#} warming of their own. The result is a decline in fish population, including in lobsters (who are cold-blooded creatures), and salmon (whose eggs find it hard to survive in higher water temps). Warmer waters also {#blank#}8{#/blank#} toxic marine bacteria, like Vibrio, to grow and cause illness in humans whenever ingested with raw seafood, like oysters or sashimi.

    And that {#blank#}9{#/blank#} "crack" you get when eating crab and lobster? It could be silenced as shellfish struggle to build their calcium(碳) carbonate shells, a result of ocean acidification (absorb carbon dioxide from the air). According to a study, scientists predicted that if over-fishing and rising temperature trends continued at their present rate, the world's seafood {#blank#}10{#/blank#} would run out by the year 2050.

Measles (麻疹) breaks out in the Northwest

    The U.S. is experiencing outbreaks of measles, a disease it had declared eliminated years ago, largely due to a drop in vaccination (接种疫苗) rates in some communities.

    An outbreak in Washington state has sickened 23 people this month, mostly children under 10. Local health officials in Clark County, declared a public-health {#blank#}1{#/blank#} on Friday. They also urged residents to track {#blank#}2{#/blank#} symptoms and call ahead before heading to medical centers.

    State officials announced the {#blank#}3{#/blank#} of measles from the U.S. in 2000, thanks to a widespread vaccination program. But travelers entering the country with measles, as well as dropping vaccination rates in some states in recent years, has led to a rise in infection. Last year, there were a total of 17 outbreaks, {#blank#}4{#/blank#} as three or more cases linked together, according to the Centers for Disease Control and Prevention. New York and New Jersey {#blank#}5{#/blank#} for roughly half of the 2018 cases. The Clark County outbreak began early last week with three confirmed cases and has since grown to 23 confirmed and two more {#blank#}6{#/blank#}. Of those cases, 20 were unvaccinated and the others are unconfirmed.

    Measles is highly {#blank#}7{#/blank#}; the virus spreads through the air by coughing or sneezing, the CDC says. Early {#blank#}8{#/blank#} include a high fever, cough, runny nose and red, watery eyes, followed by tiny, white spots inside the mouth and the red, bumpy rash (疹子) that people {#blank#}9{#/blank#} associate with the infection. Children younger than 5 or adults older than 20 are more likely to suffer from complications, according to the CDC.

    In order to prevent the further spread of the outbreak, local health officials are posting times and places where residents may have been exposed. They are urging residents who haven't been vaccinated to {#blank#}10{#/blank#} whether they have been exposed and to take appropriate action.

    The brain is a seemingly endless library, whose shelves house our most precious memories. To allow new memories to form, old information is sometimes pushed out of the brain.

    Previous studies have shown that learning new information can lead to {#blank#}1{#/blank#}. But in a new study, researchers showed for the first time how this effect {#blank#}2{#/blank#} in the brain.

    In daily life, forgetting actually has clear {#blank#}3{#/blank#}. Imagine, for instance, that you lost your bank card. The new card you receive will come with a new personal identification number (PIN). Each time you remember the new PIN, you gradually forget the old one. This process improves access to {#blank#}4{#/blank#} information, without old memories interfering.

    And most of us may sometimes feel {#blank#}5{#/blank#} when old memories interfere with new, relevant memories. Consider trying to remember where you parked your car in the same car park you were at a week earlier. This type of memory is particularly interfering.

    When we get new information, the brain automatically tries to combine it with existing information by {#blank#}6{#/blank#} associations. And when we retrieve（检索）information, both the desired and {#blank#}7{#/blank#} but irrelevant information is recalled.

    The majority of previous research has focused on how we learn and remember new information. But current studies are beginning to put greater {#blank#}8{#/blank#} on the conditions under which we forget, as its importance begins to be more appreciated.

    A very small number of people are able to remember almost every detail of their life. Though it may sound like an advantage to many, people with this rare condition often find their {#blank#}9{#/blank#} ability troublesome. In a sense, normal forgetting may help to ensure our brain doesn't become too full.
