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....

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....

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....

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!...

You might not think of plants as particularly chatty but in reality, they communicate surprisingly well with each other, especially when faced with danger. According to a recent study in the journal Frontiers in Plant Science injured plants send out emergency signals to alert neighbors to start building up their defenses....

Parents often use the expression “in the blink of an eye” to express their astonishment at how fast their children reach adulthood. However, for those with newborns, the phrase is literal given that an average baby grows between 6 to 7 sizes within the first two years! While exciting, the constant wardrobe replenishment is expensive and also results in a lot of wasted clothing. To tackle the issue, Ryan Yasin has created an origami-inspired line of clothing that expands (or contracts) automatically, resulting in a perfect fit each time....

A massive patch or “blob” of warm water experienced along the usually cool U.S. Pacific coast from 2013 to 2016 wreaked havoc on the marine ecosystem. Fishermen in Alaska reported seeing warm water sharks, while California beachgoers encountered tropical poisonous water snakes. Though the return of cooler temperatures in 2017 rid the area of most unwanted visitors, bioluminescent pyrosomes ((Pyrosoma atlanticum) have decided to stay and are now washing up along the coast in unprecedented numbers....

The Perseid meteor shower is one of the most anticipated celestial events in the Northern Hemisphere. Though the shooting stars are already lighting up the skies in small numbers, the pace will accelerate around mid-August, making them easy to view without a telescope. This year, the best time to see nature’s annual firework display will be on August 12 and 13....

With its majestic mountains, spectacular landscapes, and pristine beaches, Ireland’s Achill Island has always been a popular European tourist destination. However, since April, the rugged 57-square mile island of just 2,600 residents has gained worldwide fame thanks to the ‘miraculous’ return of a beach that was washed away over three decades ago....

Sometime between July 10 and 12, a massive iceberg the size of the US state of Delaware broke free from Antarctica’s Larsen C Ice Shelf. The crack that led to the separation was visible in the first images of the ice shelf captured by NASA satellites in 1963. However, the rift remained dormant for decades, before suddenly spreading northwards and widening by 18 miles between 2011 and 2015 and then an additional 13 miles in 2016. As of last month, the iceberg, named A-68 by the US National Ice Center, was hanging by a thread and experts knew it was just a matter of time before it broke free....

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....

Pods of crafty orcas in Alaska’s Bering Sea have figured out an easy way to get fed. Instead of seeking out the fish themselves, the clever whales chase down fishing boats and steal the entire day’s catch, as much as 20,000 to 30,000 pounds of halibut and black cod, in a single swoop....

Sommeliers are usually defined as wine experts that recommend meal pairings at restaurants. Not Martin Riese. He is America’s first and only sommelier who helps patrons select the best water to go with their choice of food. The 41-year-old discovered his unique skill of being able to distinguish the subtle differences in the taste of waters from different regions at a young age while touring Europe with his family....

Henderson Island in the south Pacific Ocean has always been known for its remarkable biological diversity and untouched ecology. Now, the remote UNESCO World Heritage site that lies 3,100 miles (5,000 km) from the closest human settlement, can also lay claim to being one of the most polluted places on Earth....

Every ocean lover knows the perils of getting caught in a rip current. Experienced swimmers know it is relatively easy to escape the narrow channel of fast moving water by floating and allowing it to drag you further into the ocean or by swimming alongside the shore. However, novice beachgoers often panic, and try to swim to land, placing themselves at risk of drowning due to fatigue. According to the US National Ocean Service, the currents kill about 100 Americans each year and account for 80% of all lifeguard rescues. These scary statistics may soon be a thing of the past, thanks to Clever GIRL (Global Intelligent Rip Locator), a smart buoy that alerts swimmers of the presence of deadly rip currents....

Some fortunate visitors to the Chicago Botanic Garden recently witnessed the rare opening of not one, but two, titan arums. Better known as corpse flowers due to their pungent odor that resembles decaying flesh, the massive plants bloom once every ten years, and that too, for only a few hours. However, that may be a good thing given that when the petals unfurl, the stench emanated is so foul that it has earned the titan arum the title of the “world's smelliest flower.”...

Every winter, hundreds of humpback whales migrate long distances from their high latitude feeding grounds in the Arctic and Antarctic to warmer tropical regions to breed and give birth. The newborn calves, which consume over 52 gallons of milk on a daily basis, have only a few months to pack on the body fat needed to survive the long trek back to cooler waters in summer. How the babies signal hunger and avoid predators during these formative months has always been a mystery to scientists....

Housing ranks high among the numerous challenges that still need to be overcome before humans can colonize Mars. The brave pioneers that make the six-month voyage to the Red Planet will need a place to reside as soon as they land. While the optimal solution would be to have the structures ready before they get there, it has thus far been a challenge given that most automated construction robots have never made it out of the laboratory. Now, there may be a glimmer of hope thanks to Massachusetts Institute of Technology’s (MIT) newly unveiled Digital Construction Platform (DCP)....

Thailand’s free-roaming monkeys are a huge tourist draw. The primates, mostly macaques, are known to boldly visit with tourists who lure them with food. One of these monkeys, in particular, has recently become a worldwide sensation for both its gargantuan size and unique social status among his peers....

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....

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!...
