With their thick white-gray fur and black rings, snow leopards are often hard to see against the rugged mountains that they call home. However, a team of photographers that included Mike Birkhead, has managed to capture amazing footage of this elusive cat walking away unscathed, after tumbling off a steep cliff....

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....

Harvey, Irma, Jose, and Maria — these seemingly innocuous names all belong to powerful hurricanes that have devastated small islands and major US cities in the past few weeks. Maria, a Category 5 storm began its path of destruction by pummeling the Commonwealth of Dominica, a tiny sovereign island country in the Caribbean, on Tuesday, September 18. Two days later, on September 20, the slightly weakened Category 4 hurricane unleashed its wrath on Puerto Rico, which was still reeling from the impacts of Irma....

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....

Earlier this year in June, a villager in Garissa County, Kenya stumbled upon a rare sight — two white giraffes! Having never seen anything like it before, he immediately ran over to inform the rangers at the nearby Hirola Conservation Center, established to protect the critically endangered hirola antelope. Cameras in hand, the troopers rushed to the area to capture the first-ever video of the extremely rare specimens, who fortunately, appeared to be in no hurry to leave....

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”)....

On September 6, the sun let its presence be felt by unleashing two massive solar flares. The first eruption, classified as an X2.2 flare, the strongest since 2008, occurred at 5:10 a.m. ET. Shortly after, at about 8:02 a.m ET, the star spewed out a bigger, and more spectacular, X9.3 flare — the most powerful on record since December 2006....

A team of astronomers, led by Alexander Boetticher of the University of Cambridge have stumbled upon what is being touted as our galaxy’s smallest known star. According to experts, EBLM J0555-57Ab, (57-Ab), which is slightly larger than Saturn, is the smallest possible size for a star. Boetticher says, “Had this star formed with only a slightly lower mass, the fusion reaction of hydrogen in its core could not be sustained, and the star would instead have transformed into a brown dwarf."...

Male humpback whales are well-known for the long sweet melodies they sing during the breeding season. The soulful songs that last anywhere from ten to twenty minutes, are not random noises, but carefully orchestrated themes that keep repeating and developing. Scientists are not sure if the mammals sing to attract partners or to deter rivals but once they get going, they tend to repeat the same tune over and over, for long periods of time....

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....

Tony Stark, aka Ironman, constantly seen manipulating 3D holographic images and floating displays projected in mid-air from his phone or tablet. Unfortunately, the rest of us are not as fortunate because the current computer-generated holograms are too bulky to be integrated into our personal devices. However, if a team of researchers from Australia's RMIT University and the Beijing Institute of Technology (BIT) is right, we may all soon be able to mimic Ironman, at least, when it comes to playing with 3D holograms....

Tired of having to choose between dark, milk, or white chocolate? Then you may want to try the pink-hued ruby. Created by Swiss chocolatier Barry Callebaut, the all-natural confection is the first new variety to come to market since Nestlé introduced the world to white chocolate in 1930....

Though it has been 16 years, Americans who lived through the September 11, 2001 terrorist attacks remember the events of the tragic day vividly. Early that morning, 19 members of the Islamic extremist organization Al Qaeda, split into four teams, each with an experienced pilot, and hijacked four commercial flights — United Flight 93 from New Jersey, American Flight 77 from Washington DC, as well as United Flight 175 and American Flight 11 from Boston....

On Tuesday, September 5, U.S. Attorney General Jeff Sessions announced that the Deferred Action for Childhood Arrivals (DACA) program will be terminated in six months and urged the U.S. Congress to pass replacement legislation before March 2018. The program, the result of a 2012 executive order by former President Barack Obama, shields young undocumented immigrants from deportation....

Scientists have long known that the world’s first flower bloomed between 250 million and 140 million years ago, during the Cretaceous period when dinosaurs dominated the earth. The single mutation was so successful that flowering plants, or Angiosperms, now make up almost 90% of all plant species, far outnumbering seed plants like conifers, that appeared on earth much earlier, between 350 million and 310 million years ago....

Fans of fidget spinners, 2017’s must-have toy, spend copious amounts of time spinning the three-pronged device with a flick of their finger. That’s because the addictive toys can rotate on their own, for only a few minutes at the most. However, if a Japanese company has its way, users will be able to relax and watch the gadget whirl for over 12 minutes with just one flick....

On Friday, August 25, Hurricane Harvey made landfall in Southern Texas as a Category 4 storm, leaving in its wake unprecedented damage and chaos. To make matters worse, the storm lingered around for days, dumping almost 52-inches of rain, breaking a 50-year record for tropical cyclone rainfall measured in a single place in the US....

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....

Most toys are fads that last a few years, or even months, before they get replaced by the next craze. However, the Slinky – the pre-compressed coil of wire, or plastic, which can “walk” on its own – has been entertaining children and nostalgic adults for over 70 years! It is therefore not surprising to hear that every August 30, fans across the U.S. celebrate this iconic toy with a National Slinky Day!...

Innovations like 3-D printing have enabled scientists to make significant progress in manufacturing various bioengineered organs and tissues. However, the one organ that has been hard to replicate is the human heart. That’s because current technology is unable to replicate the network of tiny blood vessels that transport oxygen inside a tissue as dense as the human heart muscle....

Earlier this month, millions of Americans were treated to a rare spectacle: a total solar eclipse that was visible from coast-to-coast. While Florence, a massive asteroid that will zip past our planet on September 1, will not overshadow the stunning event, it will make history of its own. According to Paul Chodas at the Center for Near Earth Object (NEO) Studies, the space rock is the largest to pass this close to our planet since the first near-Earth asteroid was discovered over a century ago....

Hurricane Harvey, which began as a tropical depression in the Gulf of Mexico on Wednesday, August 23, rapidly escalated to a Category 4 storm as it made its way towards Southern Texas. As expected the powerful hurricane, which packed 130mph winds, made landfall near the city of Rockport on August 25 at about 10:00 pm local time, causing widespread destruction. Three hours later, it made a second landfall on the northeastern shore of Copano Bay, this time as a Category 3 storm with 125 mph winds!...

Utrecht, the fourth largest city in the Netherlands, is a cyclist’s dream. Unlike other urban areas that confine riders to tiny lanes, cyclists here get priority with dedicated “bicycle streets,” where cars are considered “guests,” as well as special bike tunnels and bridges. The city is also in the process of constructing the world’s biggest indoor parking lot for bikes at its central train station. However, the over 60 percent residents who use the two-wheelers as their primary mode of transportation are still frustrated because, like cyclists all over the world, they have to make constant stops at traffic lights....
