2 plants randomly mated up to 1 million years ago to give rise to one of the world's most popular drinks

The plants that provide most of the world's coffee supply emerged around 600,000 to 1 million years ago when two other species of coffee cross-pollinated in the forests of Ethiopia, scientists have discovered. About 60% of the world's coffee supply is sourced from Coffea arabica plants, which now grow in tropical regions across the world New research, published April 15...

Deepest blue hole in the world discovered, with hidden caves and tunnels believed to be inside

Mexico's Taam Ja' Blue Hole is the deepest known underwater sinkhole in the world, researchers have discovered and they haven't even reached the bottom yet. New measurements indicate the Taam Ja' Blue Hole (TJBH), which sits in Chetumal Bay off the southeast coast of the Yucatan Peninsula, extends at least 1,380 feet (420 meters) below sea level. That's 480 feet...

Eerie, orange skies loom over Athens as dust storm engulfs southern Greece

Clouds of dust have engulfed Athens and other Greek cities, turning the sky an apocalyptic orange. The dust originated from the Sahara desert and blew across the Mediterranean Sea on strong northwesterly winds, reaching Greece Tuesday (April 23). Skies over the Acropolis and other Greek landmarks turned a dramatic, fiery hue, prompting Greek authorities to issue a health warning over...

Hidden 'biosphere' of extreme microbes discovered 13 feet below Atacama Desert is deepest found there to date

A rich microbial biosphere lies buried 13 feet (4 meters) beneath the scorched surface of Chile's Atacama Desert, new research has found. The hidden world of bacteria is one of the deepest found in Atacama soils and could inform the search for life on Mars. Microbial life has previously been recorded down to depths of 2.6 feet (80 centimeters) in...

Yellowstone Lake's weird resistance to climate change could be about to crack

In an unexpected discovery, scientists find climate change is yet to alter the ice cover on Yellowstone Lake. However, a tipping point may be coming for North America's largest high-altitude lake, researchers suggest in a new study. Located roughly 7,733 feet (2,357 meters) above sea level in the heart of Yellowstone National Park and spanning 132 square miles (342 square...

Earth's magnetic field formed before the planet's core, study suggests

Earth's magnetic field may have been similarly as strong 3.7 billion years ago as it is today, pushing the earliest date for this planetary protective bubble back 200 million years. The timing puts the magnetic field in play around the same time life was first emerging on Earth. The oldest fossils on the planet bacterial mats called stromatolites date back...

Massive heat wave and a supercell thunderstorm caused deadly, baseball-sized hailstones to rain down on Spain

A heat wave fueled by climate change helped create deadly, record-breaking hail in Spain, a new study finds. The baseball-sized hail hit northeastern Spain in August 2022, injuring 67 people and killing a 20 month old girl. Videos of the storm show balls of ice up to 4.7 inches (12 centimeters) wide dropping from the sky, smashing car windows and...

Scientists discover 1st-of-its-kind cell part born from a swallowed microbe

In a groundbreaking discovery, scientists uncovered the first known structure in complex cells that's capable of drawing nitrogen from the atmosphere and converting it into a form that the cell can use. They've dubbed the newfound cell part the nitroplast. And according to two recent studies, the researchers think it likely evolved 100 million years ago. The nitroplast probably developed...

'We were in disbelief': Antarctica is behaving in a way we've never seen before. Can it recover?

Look out over Antarctica in the summer, and time seems frozen. The South Pole's midnight sun appears to hover in place, never dropping below the horizon for weeks between November and January. But the Antarctics timelessness is an illusion. Only a decade ago, on summer nights across the coast, the sun would glide ever so slightly over the ocean, dusting...

'Unprecedented,' 'Gobsmacked', 'Unbelievable': Changes in Antarctica's sea ice could have dramatic impacts, says climate scientist Edward Doddridge

On Aug. 16, 1897, the Research Vessel Belgica set sail from Antwerp, Belgium. The ship's destination via Rio de Janeiro, Montevideo and then Punta Arenas, Chile was Antarctica, a continent that until that time remained completely unexplored by westerners. The new land was not kind to its visitors. Shortly after its arrival, the Belgica became stuck in the thick halo...

Hundreds of emperor penguin chicks spotted plunging off a 50-foot cliff in 1st-of-its-kind footage

Emperor penguin chicks have been recorded hurling themselves from a 50-foot (15 meters) cliff in Antarctica for the first time. The unprecedented footage, captured at Atka Bay in Northern Antarctica, shows roughly 700 fledglings braving a sheer drop to embark on their first swim in the ocean below. I had no idea that the chicks would be able to make...

Scientists may have pinpointed the true origin of the Hope Diamond and other pristine gemstones

Researchers may have found the true origin of the Hope Diamond, the Koh-i-noor and other famous, flawless gemstones. These diamonds, known collectively as the Golconda diamonds, are special because they have few inclusions and are very low in nitrogen, making them very clear and free of sparkle-disrupting flaws. They are also large. The Koh-i-noor, now one of the British Crown...

'Uncharted territory': El Niño to flip to La Niña in what could be the hottest year on record

El Nio is likely to give way soon, ushering in a quick switch to its opposite atmospheric and ocean pattern, La Nia. For the U.S., this climatological flip-flop will likely mean a greater risk of major hurricanes in the Atlantic as well as areas of drier-than-usual weather in the southern portions of the country. Globally, La Nia usually leads to...

What's the largest waterfall in the world?

Even our tallest buildings can't rival the staggering size of the world's most iconic waterfalls, which include Niagara Falls on the U.S. border to Canada, Victoria Falls in Zimbabwe and Zambia and Angel Falls in Venezuela. But which of these is the world's largest waterfall? Angel Falls is the tallest waterfall on land, measuring 3,212 feet (979 meters) high and...

Half of China's cities are sinking, putting most of the country's urban population at risk

Nearly half of China's major cities are sinking due to groundwater extraction and the sheer weight of urban buildings and infrastructure, a new study finds. The affected cities, which include Beijing and Tianjin, are concentrated in the eastern part of the country and along the coast. Combined with sea level rise, falling cities could expose around 10% of China's coastal...

AI-powered 'digital twin' of Earth could make weather predictions at super speeds

Scientists have created a digital twin of our planet that can be used to predict weather far faster than traditional services. The technology could help prevent some of the catastrophic impacts of disasters such as typhoons and flooding. The intensive data-crunching system could also give us a more detailed view of the future effects of climate change and reveal clues...

Part of the San Andreas fault may be gearing up for an earthquake

A section of the San Andreas fault where earthquakes occur regularly may give off a distinct signal before it trembles to life, new research finds. The signal hints at the opening and closing of cracks beneath the subsurface. This section of faultline, known as Parkfield in Central California, shakes regularly about every 22 years. It last ruptured in 2004, so...

Antarctica is covered in volcanoes, could they erupt?

Antarctica is perhaps best known for its endless expanse of ice and snow. But what many people don't realize is that hiding beneath its frosty facade are dozens of volcanoes. In fact, under the continent's massive western ice sheet sits what is considered the largest volcanic region on Earth, with as many as 138 volcanoes. Of those volcanoes, 91 were...
