A new viral video showed supporters of Donald Trump arguing that the Earth is flat.

According to The Good Liars, a comedy duo, the video was filmed at a rally for Trump. It had over a million views by Thursday.

Tumors that travel to the lungs, or lung metastases, pose a formidable challenge in the realm of cancer treatment. Conventional chemotherapy often falls short because it’s inefficient. It doesn’t directly target the lungs and accumulate in a high enough concentration to kill tumors.

My colleagues and I from the Wang lab and Zhang Research Group at the University of California, San Diego have spent the past five years developing biohybrid microrobots, tiny objects made of both natural and synthetic materials, that can be used in medicine.

As humans, we grow up playing with other children. Animals of many species likewise play with their peers. But why?

Play has its costs, especially for young animals. It uses energy that could help them grow, and it can make them more vulnerable to predators.

After analyzing the remains of 64 ancient sacrificed individuals, most of whom were children, researchers have revealed new details about human sacrifice at the ancient Maya site of Chichén Itzá.

Published today in Nature, these results show that contrary to popular belief, every one of the ritually sacrificed individuals was male. Additionally, many of them were closely related, including two pairs of identical twins, evoking important themes of Mayan mythology.

Thousands of fish have died as a lagoon in northern Mexico partly dried up amid a crippling drought plaguing the country.

The Bustillos lagoon was below 50 percent of its normal water level, local authorities said Wednesday, meaning pollutants were more concentrated and hazardous to the species that inhabit it.

When Hurricane Sally slammed coastal Florida in 2020, US pilot Dean Legidakes was aboard a scientific aircraft flying directly into the storm's core.

Once back on land, he learned how the disaster literally hit home.

Far from Parisian bistros serving up Burgundy snails, one Japanese man has figured out how to farm the slimy species -- a feat that has long eluded the French.

Toshihide Takase, 76, says he is "the only person in the world" breeding this specific delicacy after four decades of trial and error to find the right conditions.

Under a white tent on the shores of a polluted Danish fjord, volunteers and researchers prepare slender green shoots of eelgrass to be planted on the seabed to help restore the site's damaged ecosystem.

Denmark generally has a strong track record on environmental issues, but only five of its 109 coastal zones are considered healthy, according to the Danish Environmental Agency.

Over the past decade, a new form of skepticism about human activities in space has emerged. It seems to be based exclusively in the western world, and centered around the idea that increasingly ambitious space plans will damage humanity and neglect the Earth.

In China, things are different, but this will likely change eventually. Our best data, a survey published in 2020 by Lincoln Hines, shows remarkably high levels of support for space programs in China. This is in spite of the costs, the occasional debris falling from the sky and memory of the deadly Xichang Disaster in 1996 when a Long March 3B heavy carrier crashed into a nearby residential complex.

Humans can’t help being fascinated by space. And that interest seems to be making the possibility of moving humanity to another planet, like Mars or the Moon, more distinct, with Nasa hoping to set up colonies in the next few decades.

But these missions will only be viable if astronauts can produce their own food. To colonize Mars, settlers will have to grow their own food in systems that are as close to self-perpetuating as possible, with little or no input from Earth once these systems have been established. This is because Mars is 54.6 million km away from Earth, and it would take around seven months to get there using current technology.

According to a 2023 study by the International Telecommunications Union, approximately 2.6 billion people are unconnected to the internet. It’s a staggering figure.

There are many reasons for this, including poverty, reliability of service, access to linguistically and culturally relevant content, leisure time, access to equipment and training. But perhaps the most debilitating barrier is access to network infrastructure.

Apple on Monday unveiled "Apple Intelligence," its suite of new AI features for its coveted devices -- and a partnership with OpenAI -- as it seeks to catch up to rivals racing ahead on adopting the white hot technology.

For months, pressure has been on Apple to persuade doubters on its AI strategy, after Microsoft and Google rolled out products in rapid-fire succession.
