Earth's oceans are teeming with many life forms and secrets.

To better understand the ocean floor, enterprising marine scientists decided to tag tiger sharks patrolling the shallow tropical seas of the Bahamas with cameras.

Thanks to the data collected by researchers from these predators It revealed the largest known seaweed ecosystem in the worldIts area is about 35,000 square miles (92,000 square kilometers), according to a study conducted in 2022.

Seagrasses can store huge amounts of carbon which could be a crucial tool to help mitigate the climate crisis, marine biologist and study co-author Dr. Austin Gallagher recently told CNN. Gallagher is CEO of the Under the Waves Research Group.

As scientists look back at Earth's history, fossils paint a picture of other aquatic ecosystems from the past.

When researchers spotted unusual rock fragments protruding from the ground near the Napo River in Peru's Loreto region, they pieced them together and realized they were looking at something unexpected.

“We started screaming: ‘It’s a dolphin!’” said Aldo Benites-Palomino, a doctoral candidate in paleontology at the University of Zurich in Switzerland.

A newly identified dolphin species lived in a freshwater lake in the Peruvian Amazon 16 million years ago. The creature is about 11 feet (3.2 meters) long. Which makes him twice the size of some humans.

The discovery helps fill in gaps in the evolutionary history of freshwater dolphins, which are incredibly rare in the fossil record.

A long time ago

Genetic material extracted from the tomb of a sixth-century Chinese emperor enabled scientists to create a gene 3D reconstruction of the king's face.

Emperor Wu ruled China from 560 to 580 and unified the northern part of China during a chaotic period when dynasties quickly rose and fell.

While the cause of death cannot be determined for Wu, who died suddenly at the age of 36, analysis of ancient DNA revealed that he had a genetic susceptibility to stroke.

What's even more interesting to researchers is that Wu belonged to a little-studied nomadic group called the Xianbei, who lived throughout modern Mongolia and northeastern China.

On April 8, astrophotographer Stan Honda will be stationed in Fredericksburg, Texas, armed with four cameras to document the total solar eclipse.

Honda has advice for those who want to photograph the historic celestial event, whether you are Using a DSLR camera or smartphone. Get a safe solar filter for your camera and never look at the sun through an unfiltered camera, even when wearing eclipse glasses.

Honda recommends using manual focus to capture the different phases of the eclipse, such as the “diamond ring” effect, where the moon slowly blocks sunlight.

Experts also warned against counterfeit eclipse glasses entering the market. Here's how to do it Test your glasses to make sure they are safeAnd everything you need to know about eye safety before the eclipse.

A marble tomb in Mount Vernon, Virginia, is the final resting place of George Washington, the first President of the United States. But questions remained about the fate of some of his family members, such as Washington's younger brother Samuel, who died in 1781.

He and 19 other members of the Washington family are buried in the cemetery on the Samuel Harwood estate near Charles Town, West Virginia. Some graves, including Samuel's, were unmarked, likely to deter grave robbers.

Now, researchers have taken the remains exhumed from Harwood in 1999 and used new DNA analysis techniques Meet two of Samuel's grandchildren and their mother.

While the location of Samuel's grave remains a mystery, the latest technology can help identify the unidentified remains of those who served in the military.

Meanwhile, new excavations at Pompeii have revealed the site of a house renovation that likely occurred when Mount Vesuvius erupted in 79 AD.

Inside the dwelling, archaeologists found piles of building materials near one of the houses The reception area is decorated with a mythological painting.

The site offers a closer look at Roman building techniques used thousands of years ago, including sustainable materials and a stronger recipe for concrete, which can be applied today.

Separately, researchers discovered the remains of what site director Francesca Giarelli of the Red River Archeology Group described as a “magnificent” Roman villa complex, including… A collection of small, tightly bound lead manuscriptsin a village in the English county of Oxfordshire.
