Earth.com staff writer Beaches often feel eternal when we stand at the edge of the water. Waves arrive in steady rhythm. Wind moves across open sand. People gather at the shore for peace, joy, and work. Yet these places are changing faster than many realize. Scientists warn that beaches face steady erosion and loss as climate and human development reshape the coast. Urgent action and cooperation is needed before many shores slip away. Rising seas and growing cities press against sandy [...]

Two newly described pterosaur species from Mongolia’s Gobi Desert are reshaping how scientists picture the Late Cretaceous skies. Found in the same rock layer, the pair represents strikingly different size classes – one with an estimated wingspan of about 11 feet, the other likely under 6.5 feet. Both pterosaurs lived roughly 96 to 90 million years ago, yet their coexistence hints at a more finely divided airborne ecosystem than previously recognized. Pterosaurs [...]

A newly analyzed site in northern Kenya is reshaping the story of early human technology. An international team reports more than 1,200 stone tools from three stacked layers that span roughly 300,000 years – from 2.75 to 2.44 million years ago. The study’s central message is simple yet striking. Even as floodplains turned to grasslands and back again, early hominins stayed consistent – choosing the same materials, shaping them in the same way, and relying on a proven [...]

Earth.com staff writer Sixty-six million years ago, some dinosaurs may have had a trick up their sleeves – or rather, up their legs. According to a new study, a pair of long-necked, four-legged dinosaurs that once roamed South America could do something most of their giant relatives couldn't. They could stand tall on their hind legs for extended periods. This ability gave them a serious advantage. It helped them reach leaves on tall trees that others couldn't reach and [...]

Earth.com staff writer High above the forest floor, two quiet giants move through the treetops of Brazil's Atlantic Forest. The northern and southern muriquis, known for their calm nature and long limbs, once thrived across the region. Now, the forest that is home to muriqui monkeys is disappearing faster than they can adapt. A recent study published in the Journal for Nature Conservation shows just how severe their struggle might become. Muriqui habitat is [...]

A team working in Brazil’s Amazon National Park has detected DNA from a previously undescribed Bartonella bacterium in local sand flies. The signal clusters genetically near to other species that are already tied to Andean bartonellosis. This serious infection can cause high fever or wart-like skin lesions in people. The finding does not confirm human disease, and the researchers are clear about that. It does, however, sharpen attention on bartonellosis, an infection that can be caused [...]

A team working in Brazil’s Amazon National Park found DNA from bacteria in the Bartonella group inside local sand flies. The sequences look close to two Andean species that are known to make people sick, but the Brazilian strain has not been tied to illness in people. The word Bartonellosis refers to infections caused by Bartonella bacteria that can linger in the body and cause long running problems in people and animals. Doctors know it from cat scratch disease, which is caused by [...]

Earth.com staff writer We know that exercise strengthens your muscles, heart, and lungs. But it turns out it also gives your immune system a serious upgrade. If you've spent years jogging, biking, swimming, or even power walking, your body might be better prepared to fight off viruses and even cancer. A new study has revealed something interesting about people who've trained their bodies with endurance exercise for decades. Their immune cells – especially the “natural [...]

Earth.com staff writer By the end of this century, cows, chickens, goats, and other farm animals may face serious physical stress just trying to stay alive. Scientists have developed a method to predict how different animals will respond to rising temperatures – and the outlook is grim, especially if the planet warms by 2°C (3.6°F) or more. Using climate models and massive datasets from three countries, researchers developed a global method to forecast how heat will affect livestock [...]
