Humans use electricity to light up the night sky. But did you know that nature itself can glow, too?

    {#blank#}1{#/blank#}. Some use their lights to communicate. Others shine to hunt, to mate or to protect themselves. The vampire squid, for example, gives out a cloud of light to scare enemies.

    {#blank#}2{#/blank#}.

    In 2013, the US company Gleaux said it had created the world's first light-producing plant, reported the Daily Mail.

    {#blank#}3{#/blank#}.

    “People have dreamed about this stuff for many years,” said Alexander Krichevsky, the company's founder.

    He and other researchers are working toward a future in which glowing plants replace lamps and glowing trees line highways.{#blank#}4{#/blank#}, making them glow to let farmers know when they need water or are ready to be picked.

    While GleauX is working on glowing plants, the French company Glowee is trying to use glowing bacteria to light up shop windows and street signs. It is the same type of bacteria that causes certain sea animals to light up.

    {#blank#}5{#/blank#}.The company is now working on a light that shines brighter, lasts longer and comes in different colors.

    “Our goal is to change the way we produce and use light,” said Glowee founder Sandra Rey. “We want to offer a global solution that will reduce the 19 percent of electricity consumption used to produce light.”

A. People are also creating glowing bacterial art that you can hang in your home

B. Scientists have found many glowing creatures, most of which live in the ocean

C. Krichevsky also hopes the technology could be used in crops

D. Researchers around the world are looking into nature's lights for new ideas

E. It is a genetically-modified plant that glows like fireflies do

F. In 2016, Glowee created a bacteria-powered light that glows for three days

G. This technology could help us save much energy

Learn to Manage Your Time in College

    A common view both among and of college students is that they are always short on money. While this may be true, many college students are also always running short on something else: time. {#blank#}1{#/blank#} Here are a few things to consider:

    Manage your academic time.{#blank#}2{#/blank#}Consequently, your academic work should always come first when it comes to arranging your time in order of importance. When looking at your schedule for the week, figure out what your academic commitments look like. What time do you have classes? How much homework do you have to do? What assignments are due? When do you have major exams or quizzes?

    Manage your personal time. It's an unrealistic expectation to think that you can study, go to class, and work all day, every day.{#blank#}3{#/blank#}Make sure to allow yourself time to go to something fun in the yard, attend a meeting for your favorite club, and just hang out for an hour or so at night with friends over dinner. Doing things that make your personal time more enjoyable and not totally focused on school? can actually improve your productivity when working on projects later.

    Keep your health in mind. When people's schedules are tight, one of the first things to go is sleep. While it may be common among college students, a lack of sleep is more hurtful than you might think. It can throw everything into disorder: your mental health, your physical health, your stress level, and, of course, your schedule. {#blank#}4{#/blank#}

A. Try your best to keep a routine on a regular basis.

B. Remember that your brain needs to have a break, too.

C. If what you're using isn't working for you, don't give up.

F. Making a list and then crossing items off as they are completed can be satisfying.

G. Take moments to plan out the time for a week: your homework, social time and sleep.
