Researchers inside a cave system known as Rising Star, located near modern-day Johannesburg. Photo: Mathabela TsikoaneDiscoveries from a subterranean cave system in South Africa are prompting paleoanthropologists to rethink what makes us human. New findings reveal a small-brained human relative known as Homo naledi buried its dead and carved symbols on walls inside the system. Both these behaviors were previously associated with our species or the big-brained Neanderthals with which we interbred.

Jupiter Mission Set to Explore Icy Worlds

A historic mission to Jupiter is about to blast off. The European Space Agency’s spacecraft nicknamed Juice—for Jupiter Icy Moons Explorer—is set to begin an eight-year journey toward the planet and three of its largest moons. Juice is scheduled to launch Friday morning Eastern Time from a spaceport in Kourou, French Guiana, after an earlier attempt was scrubbed because of lightning risk.
T. Rex Had Lizard-like Lips That Covered Its Teeth
  + stars: | 2023-03-30 | by ( Aylin Woodward | ) www.wsj.com   time to read: 1 min
Conjure up an image of Tyrannosaurus rex in a Hollywood blockbuster. The meat-eating dinosaur’s long, serrated teeth taper to sharp points that protrude from a gaping maw bared wide in a roar. As the predator closes those jaws around its prey, its upper teeth remain exposed in a fanged smile. But new research is challenging these popular-culture depictions. The teeth of T. rex and its two-legged, three-toed meat-eating kin—known as theropods—were likely covered by thin, scaly lips resembling those of some modern lizards, according to a study published Thursday in the journal Science.
It’s safe to say many people eat Oreos the same way. They twist them apart, then consume the cookie as two separate creme-covered wafers. Yet more than a century after the Oreo’s inception, many connoisseurs haven’t solved a frustrating problem: how to twist it so both wafers end up with filling on them.
An artist’s impression of ‘Oumuamua, the first interstellar object discovered in the solar system. Nearly six years ago, a space object roughly the size of a football field baffled scientists as it zipped through our solar system. The irregular shape and motion of the object, dubbed ‘Oumuamua, led to one of the most controversial astronomical mysteries, with theories that ranged from asteroid to alien probe. But a study published Wednesday in the journal Nature offers another answer: ‘Oumuamua is a typical comet that expelled gas in an odd way as it traveled through our solar system.
Earth's axis — the invisible line around which it spins — is bookended by the north and south poles. But their geographic locations aren't fixed: As the Earth's axis moves, so do the poles. If you average out thousands of years of observation the Earth's axis points in a single direction — toward the North Star, also known as Polaris. The recent change to Earth's axis won't affect our everyday lives, but it could slightly tweak the length of our days. But let's be clear that this would be a tiny, tiny, tiny effect," he said.

Superconductors can conduct electric currents with perfect efficiency. However, these materials typically need to be extremely cooled, to around minus 320 degrees Fahrenheit, and subject to high pressures, like those found in the center of the Earth. Researchers are trying to solve this conundrum and the potential technological impacts.
14 ocean animals have gone extinct in the last 100 years, and 72 are on the verge of extinction. An international deal was reached Saturday to protect marine wildlife, after decades of talk. At least 41% of marine species are at risk of climate change, the International Union for the Conservation of Nature (IUCN) said in 2022. An international treaty was agreed on Saturday, after decades of negotiation. Here are the 14 extinct ocean animals (that we know of), and dozen others that are on the verge of extinction.
Even if intelligent aliens aren't flying overhead, though, many experts believe they're out there. Nobel Physics Laureate Didier Queloz speaks during a press conference at the Royal Swedish Academy of Sciences in Stockholm, Sweden. Jonas Ekstromer /TT News Agency via AP"I can't believe we are the only living entity in the whole universe. Queloz had just won the Nobel prize in physics for his discovery of the first exoplanet orbiting a sun-like star. He said that his work has led him to become "absolutely convinced" that humans will detect alien life in the next 100 years.
Billions of miles away, in a distant part of our solar system, astronomers have found a new ring orbiting a small, icy world. But this newly discovered ring is unlike the telltale halos of ice and dust that orbit planets such as Saturn and Jupiter in a key aspect—it is unusually far from its host body, according to a study published Wednesday in the journal Nature.
A green-glowing comet traveled within 26.4 million miles of our planet on Wednesday, moving past at 128,000 miles an hour on its way back to the outer reaches of the solar system. Here’s a look at other space objects like this one, and why they matter to astronomers.
How to See the Rare Green Comet That Is Passing By Earth

A rare green comet that last passed through our solar system 50,000 years ago will fly within about 26 million miles of Earth on Wednesday, harmlessly zipping by at a blistering speed. The sun-orbiting cosmic snowball, made of frozen rock and dust, first enthralled amateur and professional astronomers and photographers alike during its recent journey through the inner solar system. The comet has become increasingly more visible in the nighttime sky with binoculars and telescopes in the Northern Hemisphere over the past month or so, according to National Aeronautics and Space Administration astronomers.
Vast Maya Kingdom Is Revealed in Guatemalan Jungle

Part of the ancient Maya city El Mirador in northern Guatemala that was detailed using light-detection and ranging equipment. Nestled in the jungle of northern Guatemala, a vast network of interconnected Maya settlements built millennia ago has been mapped in unprecedented detail. The civilization featured towering pyramids, palaces, terraces, ball courts and reservoirs connected by a sprawling web of causeways, an international group of archaeologists reported during a presentation at Francisco Marroquín University in Guatemala City this month.
