A question that members of the research team often get regarding our work in the South Australian outback is simply how we know where to excavate fossil beds. It’s a good question—an important aspect of the paleontological process is simply identifying the best places to look for fossils.
Emily Hughes has been following her mother, paleontologist Mary Droser, into the field all her life. This summer the family is back in Australia digging up some of Earth’s oldest fossils.
“The seed comes from the tree, the tree comes from the seed. It’s like the chicken and the egg. If people want to understand it, they will break the seed apart — they will actually kill it — to see the cells, the chromosomes and the genetics. There is another way to look at this. I plant a seed and a miracle happens — something new is born out of this carbohydrate and protein, a new life is born. This is a miracle, you see? The miracle of life.”
Public enemy number one, it might be called: Eurasian watermilfoil. It’s not on the FBI’s Ten Most Wanted list, but maybe it should be, say scientists who study lakes. The invasive weed’s crime? It crowds out native underwater plants, fouls boat propellers and smothers swimming areas in freshwater lakes across the northern U.S. The invader’s…
Almost five years ago, I invited two eminent gemologists to post their perspectives on linking environmental conservation and gemstone mining through an innovative mechanism of supply chain tracing. In this post, Dr. Laurent Cartier, one of the authors of the earlier article, shares perspectives on how the colored gemstone sector in post-sanctions Myanmar / Burma…
In a new study, scientists say they have found evidence along the New Jersey coast that an extraterrestrial object hit the earth at the same time a mysterious release of carbon dioxide suddenly warmed the planet, some 55.6 million years ago. The warm period, known as the Paleocene-Eocene Thermal Maximum (PETM), is often cited as…
Polar expeditions to explore the ocean are not for the faint of heart. Above the water’s surface, you better be on alert for polar bears. Below, you better be game for diving 60 feet under sea ice into freezing temperatures. Watch National Geographic grantee Branwen Williams lead a team to the Canadian Arctic to do both in an effort to better understand how our oceans and the climate are changing over time.
Geologist Gina Moseley started caving for sport when she was 13 years old, and now she’s in it for science. Moseley is constructing the first cave-based record of past climate change for Greenland.
The latest in the Drones and Small Unmanned Aerial Systems Special Series, in which Kike profiles interesting information, research and thoughts on using drones, UAVs and remotely piloted vehicles for journalism and photography. The combination of light (photo), drawings (gram) and measurements (metry) are known as photogrammetry. Until recently, photogrammetry was a very specific niche within the…
National Geographic grantee Eduardo Cartaya and his team descend into a volcano’s toxic ice caves on a mission to protect climbers and learn about microbial life in this eerie, otherworldly environment.
Follow Kenny Broad, an environmental anthropologist and National Geographic Expeditions Council grantee, as he explores a narrow underwater cave in the Bahamas.
Rivers and lakes were constructing with lumber long, long before people (or beavers) ever had the idea.
It was a cold and blustery October day! Our tour bus had stopped at a desolate site where a group of visitors had lined up, cameras at the ready, all anxiously waiting. Then suddenly it happened! Perhaps by now you’ve guessed what these people were waiting for. Right after I took this photo, I rushed…
The fossil called “Gamla,” star of the National Geographic Channel documentary, “Death of a Sea Monster,” has been in a museum basement since 2009. Now for the first time, it’s being put on display.
Some residents who live on Treasure Island in the San Francisco Bay are concerned about exposure to toxins, because many areas on the island have been marked as radioactive. While officials at the California Environmental Protection Agency have not currently identified unsafe levels of contamination in homes on the island, young people who live there still worry about potential health risks.
