On Monday, January 15, Americans will celebrate the life and achievements of civil rights leader Martin Luther King Jr. (MLK). Born in Atlanta, Georgia on January 15, 1929, the activist was originally named Michael King after his father, a pastor at Ebenezer Baptist Church. However, after a trip to Europe in 1934, King Sr. changed both his and his son’s name to Martin Luther in honor of the German theologian who initiated the Protestant Reformation in the 16th century....

For most Americans, the holiday season begins around Thanksgiving. However, for Kathy Rombeiro and her dad, Edmundo, it starts in September, when they begin the laborious process of converting their Novato, California home into a winter wonderland. By the first Sunday of December, the ordinary suburban home is transformed into a magical “Christmas House,” complete with over 200,000 lights, fake snow, model trains, countless decorations and figurines, and even a real-life Santa Claus (Edmundo) on a sleigh....

With Christmas less than two weeks away, you are probably getting into the festive spirit. For those living in the United States, this means seeking out the perfect Christmas tree, decorating the house with lights, playing in the snow, or watching seasonal movies with family and friends. However, not everyone celebrates the holiday in the same way. Here are some fun Christmas traditions from around the world....

Facial recognition is a complex task which requires as many as 200 neurons in the brain’s temporal lobe, called “face patches,” to fire up simultaneously within milliseconds. Hence the skill has always been believed to be the realm of “intelligent” animals such as humans, monkeys, apes, dogs, and horses. Now, British scientists have found that the unassuming cud-chewing sheep also possess this skill....

At first sight, Alma Deutscher, a twelve-year-old girl from England with a penchant for dresses, appears to be like any other normal tween. She loves to skip rope, read, bake cookies, and engage in make-believe play with her younger sister Helen. But this unassuming youngster, who composed her first musical sonata at age six, first short opera at age seven, and first full-length opera based on Cinderella at age ten, is anything but average. Though her parents downplay her extraordinary talent as “imaginative, just a child playing,” young Alma is being hailed as “little Mozart” by the music world....

Albert Einstein, the genius behind the theory of relativity, which provided a new framework for all of physics and proposed new concepts of space and time, has recently been making headlines again. However, this time it is not for a new scientific breakthrough, but because of two handwritten notes the scientist gave a bellboy 95 years ago....

Houston residents, recovering from the devastation caused by Hurricane Harvey, finally have something to cheer about – a World Series victory. Thousands of fans lined up on the city streets on Friday, November 3 for a parade celebrating the Houston Astros who won the baseball championship with a resounding 5-1 score against the Los Angeles Dodgers in the seventh game. What makes the much-needed win even more special is that it is the first time the 56-year-old team has brought home the coveted trophy....

North Americans will enjoy an extra hour of fun, or sleep, this weekend! That’s because Daylight Saving Time (DST) ends on November 5, which means that the clocks will turn back an hour. In addition to adding an extra 60 minutes to Sunday, this simple action effectively moves an hour of daylight from the morning to the evening, making it easier to wake up....

Mention the word superhero, and the images that come to mind are of fictional characters like Spiderman, Wonder Woman, or Batman. However, veteran photographer Josh Rossi has used his camera to unveil the world’s real superheroes – six young children who are battling severe diseases and disabilities....

Many kids dream of venturing into space to search for new planets or to conduct cutting-edge research on the International Space Station (ISS). In August 2017, twelve eager men and women came one step closer to realizing their lifelong ambition, when they reported to the Johnson Space Center in Houston to begin two years of grueling training. If they succeed, they will be NASA’s biggest graduating class of astronauts since 2000....

Wildfires are a common occurrence in California from early spring to late autumn due to the dry, windy, and hot weather conditions. However, the Golden State has never experienced anything as devastating as the fires that are currently burning through parts of Northern California. Though it has been four days since the first flames ignited, firefighters still have no control over the blazes that extend all the way from Napa to Mendocino County....

Columbus Day has been a fixture on American calendars since 1937, when President Franklin D. Roosevelt declared October 12 a federal holiday to honor the Italian explorer who “discovered” the Americas in 1492. However, the holiday, whose date has since been changed to the second Monday of October, has always been somewhat controversial. Many people believe that Christopher Columbus should not be given credit for “discovering” the continent, since Native Americans had already been residing there for generations....

In most countries being able to drive is a fundamental right, afforded to anyone that is of legal age. However, this is not the case in Saudi Arabia. In this ultraconservative Islamic nation, women are not allowed to do many things that females worldwide take for granted, including getting behind the wheel. Though there is no official law in place, local authorities consistently turn down license requests from women, effectively resulting in a defacto ban. Those who defy the unwritten rule often end up losing their jobs and even risk getting arrested and jailed....

The next time your brain refuses to recall a simple fact or name, be thankful. That’s because according to University of Toronto professors Blake Richards and Paul Frankland, could be a sign that your brain is getting rid of unnecessary information so that it can operate more efficiently, and help you make better decisions....

Pedestrian etiquette – things like not walking into oncoming traffic or keeping to the right of the sidewalk – comes naturally to humans. However, while robots have been programmed to accomplish many things, teaching them to navigate among crowds has proved a challenge because it is hard to accurately predict each person’s path. Now, a team of MIT engineers, led by Steven Chen, have overcome the hurdle with a knee-high autonomous machine that can seamlessly weave itself through pedestrians, paving the way for errand-running and pizza delivering robots....

Given that sharks have been around for millions of years and can live for as long as 400 years, it is evident that the formidable species has developed an arsenal of survival mechanisms. However, a lemon shark’s two-year quest to rid itself of a piece of ingested stainless steel through its skin, and self-heal Wolverine style, has impressed even the most jaded scientists....

Every year on September 19, residents of Mexico City conduct an emergency evacuation drill to mark the anniversary of an 8.0 magnitude earthquake that killed about 10,000 residents in 1985. Yesterday was no exception. At 11:00 am, thousands of people left their homes, offices, and shops and made their way to the predesignated safe zones. Little did they know that within just two hours, the evacuation warning bells would ring again. Only this time, they were instantly followed by the violent shaking of a 7.1 magnitude earthquake....

A week ago, on Tuesday, September 12, Apple unveiled its latest offerings to eagerly awaiting fans. The 2017 product showcase held at Apple Park, the company’s new “spaceship” headquarters in Cupertino, CA, included an upgraded Apple Watch, 4K Apple TV, as well as the next generation iPhones – 8 and 8 plus. Just as the presentation appeared to be drawing to a close, company CEO Tim Cook, took to the podium mouthing the late Steve Job’s familiar, “one more thing . . .” phrase, before introducing the much-anticipated iPhone X (“ten”)....

Just days after Hurricane Harvey struck Texas and parts of Louisiana, leaving behind unprecedented destruction, an even stronger tropical cyclone was reported heading towards Florida. Irma, the most powerful Atlantic Ocean hurricane in recorded history, first brought chaos to the Caribbean, devastating islands like Barbuda and St. Martin on September 6, where it struck with Category 5 winds that at times reached up to 185 mph....

Over a 100 million years ago, an 18-foot (5.48 meter) long, 2,500-pound (1,133 kg) pineapple-shaped dinosaur met an untimely death when it was swept away by a river in what is now Alberta, Canada. Fortunately for us, its body ended up situated back-first on the muddy floor of an old seaway. This helped preserve the ancient behemoth’s front half in such extraordinary 3-D detail that the armored dinosaur almost looks alive....

While Japan is known to have higher than average rates of stomach cancer, the residents of the town of Kaneyama in Yamagata Prefecture appear to be particularly susceptible to the gastric ailment. After a recent report revealed that the municipality had one of the highest stomach cancer fatality rates out of the nation’s 344 “secondary medical districts”, the town officials decided to get its 6,000 residents tested....

The total solar eclipse on August 21, 2017, is the first of its kind to go coast-to-coast across the continental United States in nearly a century. While the partial eclipse will start earlier and end later, the total eclipse will travel from Oregon to South Carolina in a speedy 93 minutes. Its narrow, 70-mile-wide, path of totality will begin at Lincoln Beach, OR at 10:15 a.m PDT (1:15 p.m. EDT) and continue through Idaho, Wyoming, Montana, Nebraska, Iowa, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia and North Carolina, before ending in Charleston, SC at 11:48 a.m. PDT (2:48 p.m. EDT)....

Worms are not the first thing that come to mind when one thinks of space travelers. However, that is exactly what the researchers from Tufts University decided to send to the International Space Station (ISS) on January 10, 2015. Some were left whole, others had their head or tail sliced off, while a few poor souls went to space with neither head nor tail! The group of planarian flatworms (Dugesia japonica) selected for their ability to regenerate any body part, were in varying states. Some were left whole, others had their head or tail sliced off, while a select few were shipped with neither head nor tail!...

To say that California’s redwoods are amazing is an understatement. The majestic trees that have been around for millions of years have a lifespan of up to 2,000 years and can reach heights of over 300 feet, so tall that the tops are often invisible. Over the years, researchers have been able to discover a lot about these sturdy survivors that are resistant to pests, fire, and rot, grow three to ten feet a year, and capture more human-generated carbon dioxide (CO2) than any other tree on Earth....
