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....

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.”...

On Tuesday, June 1, President Donald Trump fulfilled yet another campaign promise by announcing that the US was withdrawing from the 2015 Paris climate agreement. The goal of the historic pledge signed by 195 countries is to curb the use of fossil fuels to ensure that average global temperatures do not increase more than 2°C (3.6°F) above pre-industrial levels. Environmentalists believe this is a critical threshold above which the planet could experience irreversible impacts, such as an unprecedented rise in sea levels and widespread plant and animal extinction....

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....

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)....

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!...

Supermarket shelves are filled with plant-based milk alternatives, including soy, almond, and coconut milk, that cater to the lactose intolerant or those concerned about livestock welfare and environmental sustainability. While the milk-free options work well with cereal or in coffee, they fail miserably when it comes to making derivatives like cheese or yogurt. However, these shortcomings may soon be a thing of the past thanks to California-based start-up Perfect Day, which has figured out how to create lactose-free dairy milk in a laboratory!...

Tim Caro, Professor of Wildlife Biology at the University of California, Davis (UC Davis), has made it his mission to understand the evolution of coloration in mammals. The researcher spent twenty years investigating why zebras sport black and white stripes (to ward off flies) and even wrote a book, Zebra Stripes, about his epic discovery. Now, Caro has solved the age-old mystery of why giant pandas also sport the dual coloration....

Ever since Malaysian ecologist-architect Ken Yeang introduced the concept in the 1990’s, living walls and rooftops have become an increasingly common sight in both residential and commercial buildings. In addition to looking good, planted exteriors also help cut energy costs, and in the case of rooftop farms provide urban dwellers with homegrown produce. Now, Stefano Boeri wants to take green architecture to the next level with “Forest Cities” to combat China’s air pollution woes....

While smartphones continue to get increasingly sophisticated and resilient, the same cannot be said about the display screen. The Gorilla Glass cover used for most high-end cell phones tends to shatter easily, leaving owners with little choice but to pay for an expensive replacement screen or buy a new device altogether. However, this issue may soon be a thing of the past thanks to a new self-healing, Wolverine-inspired material which automatically repairs itself within 24 hours....

On Saturday, April 29, 2017, President Donald Trump celebrated his 100th day in office. The marker has become a perennial fixture on the American political calendar since Franklin Delano Roosevelt (1882-1945), the 32nd President of the United States, helped the country limp back from the Great Depression with a flurry of new legislation within his first 105 days in the White House....

Flying cars have been in the works since 1946, when aeronautical engineer Ted Hall created two prototypes of the ConvAirCar. Unfortunately, a crash landing due to low fuel caused the hybrid vehicle’s manufacturer, Convair, to lose interest and shut down the venture within a year. While there have been numerous attempts since, none have gone beyond the experimental stage. That is about to change thanks to a slew of new and established companies that are determined to make this 70-year-old quest a reality....

In your biology class, you may have learned that lungs help us breathe while bone marrow, found in flat bones such as the hip bone, produces red and white blood cells through a process called hematopoiesis Now, University of California, San Francisco (UCSF) researchers have discovered that in addition to being a crucial part of our respiratory system, lungs also play a major role in the production and storage of blood cells....

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....

Given that more than 65% of infectious diseases that affect humans originate from other animals, the most logical way to stop them would be to locate the source. However, studying wildlife for clues about the origin of the next epidemic is like looking for a needle in a haystack. As a result, scientists and health officials are forced to combat illnesses like the recent Zika Virus, after they spread....

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....

Like most people, Gal Rozov hates folding laundry. But instead of complaining, the software developer decided to put his programming skills to work and create a laundry-folding robot! In 2012, after spending two years researching the most efficient design, Rozov moved from Israel to California and founded FoldiMate Inc. It took another four years, but by 2016, he had a working prototype of the namesake robot....

While the fact that Julia is “Sesame Street’s” first new Muppet in a decade is certainly newsworthy, that is not the only thing that makes her special. The cheery, green-eyed 4-year-old who has autism is also here to expose young kids to children with autistic traits and teach them about acceptance....

In case it has slipped your mind, this Saturday is April 1st, or, as is popularly called, Fools’ Day. The origin of this fun day, when pranking people is encouraged, is hazy. Some believe the tradition began in 1582 when the world transitioned from the Julian calendar, which started the year in April, to the currently used Gregorian calendar. Others think it was to celebrate the start of spring. Though individuals often prank each other, it is corporations that really get into the spirit with elaborate gags. Here are a few that were credible enough to fool people for days....
