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....

While U.S. President Donald Trump, who pulled out of the Paris climate agreement on June 1, is convinced global warming is a “hoax,” the deteriorating condition of the world’s coral reefs seems to suggest otherwise. Often called “rainforests of the sea,” the incredible ecosystems that occupy less than 0.1 percent of ocean’s surface are home to almost 25 percent of all marine species. Unfortunately, the rising ocean temperatures caused by global warming are wreaking havoc on these fragile organisms....

Though plastic shopping bags are incredibly cheap and useful, their disposal causes widespread pollution. That's because the non-biodegradable polyethylene takes centuries to decompose and is also detrimental to wildlife who often mistake the colorful debris for food. Now, we may have an unlikely ally to help clean up our trash – a small wax worm bred primarily for use as premium fish bait....

Memorial Day, which will be celebrated on Monday, May 29 this year, is one of the most important holidays in the American calendar. Observed annually on the last Monday of the month, it honors the men and women who have died while serving in the United States Armed Forces. Though the tradition is believed to have been started by local communities in the late 1800’s, the first official Memorial Day celebration is credited to Waterloo, New York. On May 5, 1866, the town’s residents organized a community-wide event to pay respects to perished soldiers by decorating their graves with flowers and flags....

As you are firming up your summer plans, you may want to pencil in the total solar eclipse on August 21. Dubbed the ‘Great American Eclipse,' it is not just the first total solar eclipse visible from the contiguous United States since February 26, 1979, but also the first that can be seen across the country, from the Pacific to the Atlantic, in almost a century. The last time the celestial phenomenon was experienced coast-to-coast was on June 8, 1918!...

Forty-seven years ago, on April 22, 1970, twenty million Americans took to the streets to voice their concern about the deteriorating environment and urge the government to take action before it was too late. The grassroots movement, which is now celebrated by over 2 billion people in 192 countries, led to the enactment of numerous environmental laws, including the Clean Air Act of 1970 and the Endangered Species Act of 1973....

On April 4, the world woke up to the news that Syrian President Bashar al-Assad’s army had conducted airstrikes targeting the town of Khan Sheikhoun in the rebel-held province of Idlib. The attack killed 85 people, including 16 women and 23 children, and wounded over 350. Images of the victims choking and gasping for breath on social media and reports from Doctors Without Borders, which supports medical clinics in rebel-held areas, led to the conclusion that it had been a chemical attack. Experts speculate the government used sarin, a toxic nerve gas, massive exposure to which can cause instant death....

Researchers have long maintained that we sleep to accomplish a neural or physiological function that cannot be completed when awake. Why else would higher animals waste a third of their lives sleeping when they could be doing more important things like looking after their families, working, or hunting? Some scientists believe sleeping helps recharge the body, while others think it is important for consolidating newly-formed memories. Now, there is new evidence which suggests that the purpose of sleep may be to forget some of the millions of new things we learn each day....

Residents of the US East Coast still recovering from last week’s record snowstorms will be happy to know that today is not just the first day of spring, but also the International Day of Happiness. First celebrated in 2013, this fun holiday was established by the United Nations (UN) to remind us that "the pursuit of happiness is a fundamental human goal."...

Every year on March 17, millions of people worldwide celebrate St. Patrick’s Day by participating in parades, wearing green, and searching for leprechauns in the hopes of finding gold. So who was this clergyman whose death anniversary is celebrated with such gusto, and how did the fun traditions associated with the holiday begin? Read on....

Even if math doesn’t rank high on your list of favorite subjects, chances are you still look forward to Pi Day. That’s because though the discussions may begin with Pi — the ratio of the circumference of a circle to its diameter — they invariably end with a piece or two of yummy pie! The event is commemorated on March 14 because though the irrational number (its decimal representation never ends and never repeats) has been calculated to over ten trillion digits, it is widely recognized as 3.14....

In August 2013, billionaire entrepreneur Elon Musk released a 57-page white paper concept for Hyperloop — a supersonic mass transit system between high-traffic cities that lie within short distances. The founder of Tesla Motors and SpaceX envisioned it to be a frictionless system where pods inside low-pressure, vacuum-sealed tubes would transport passengers and cargo at up to 760 miles an hour — approximately the speed of sound. Powered by solar energy, it would be strong enough to withstand extreme weather and earthquakes....

On Sunday, March 12, most Americans will ‘lose’ an hour by moving their clocks forward sixty minutes. This small sacrifice that marks the start of Daylight Saving Time (DST) is designed to allow residents to enjoy longer days during the upcoming spring and summer months....

The steady increase in global temperatures has been particularly disastrous for the polar ice caps. Experts warn that if this trend continues, there will be no late summer ice in the Arctic region by the 2030’s. The most effective solution, of course, is to reduce our greenhouse gas emissions before it’s too late. But since that is not happening, scientists are frantically trying to come up with alternative ways to try to reverse the situation....

About forty light years, or 235 trillion miles, away in the constellation Aquarius lies a planetary system with seven Earth-sized planets, at least three of which could be habitable. The exciting news was revealed to the public at a NASA press briefing and through the release of a study in the journal Nature on February 22....

New Zealand is no stranger to beached whales. Every year, rescuers help refloat many disoriented mammals that get stuck in the coastal waters or sand during low tide. However, last week’s simultaneous stranding of two pods, totaling over 650 pilot whales, in the shallow muddy waters of Golden Bay at the northwest tip of South Island is almost unprecedented. Local marine experts say it is the largest known whale stranding since 1985 when 450 of the mammals were found beached in Auckland, and the third largest on record....

For many of us, the mere thought of wiggling fingers approaching our rib cage or moving towards our underarms is enough to elicit squeals of laughter and giggles. However, while we all know that tickling makes us happy, Michael Brecht, a professor at Berlin’s Humboldt University, says, it is “one of the most poorly understood forms of touch.”...
