A groundbreaking study reveals sperm struggle to navigate in microgravity, but researchers discovered a promising solution. The findings could help future space colonists start families beyond Earth.
As commercial moon bases and Mars missions shift from science fiction to reality, researchers are urging the world to tackle a critical question: how does space affect human reproduction? A new study reveals urgent gaps in our knowledge and calls for international guidelines before we venture too far from Earth.
Ancient humans in China crafted sophisticated stone tools during a brutal ice age, proving creativity thrives under pressure. The discovery rewrites what we thought we knew about early human innovation.
Australian researchers are solving the puzzle of how humans might have babies in space, discovering surprising challenges that need solutions before we can settle other worlds. Their groundbreaking experiments reveal both obstacles and paths forward for space-faring families.
Chinese scientists are studying human embryo development in microgravity to understand if we can safely have babies beyond Earth. The research could be crucial for future moon and Mars settlements.
New fossil discoveries reveal how our uniquely powerful thumbs helped make us human. The evolution of our hands may be just as important as our big brains in shaping who we became.
Scientists discovered tiny genetic "switches" that shaped human language ability before we split from Neanderthals. These ancient regulators still influence how we learn and use language today.
Scientists discovered ancient human ancestor fossils in Morocco dating back 800,000 years, revealing that North Africa played a central role in human evolution. The findings are transforming our understanding of how early humans lived, worked, and mourned their dead.
Four astronauts launched aboard NASA's Artemis 2 mission on April 1, marking humanity's first return to lunar orbit in over five decades. The crew will travel farther into space than any humans before them during their historic 10-day journey.
Four astronauts aboard NASA's Artemis 2 mission crossed into the moon's gravitational sphere on April 6, becoming the first humans to reach lunar space since 1972. Tonight, they'll break the distance record for human spaceflight.
Scientists discovered that male Neanderthals and female humans formed most ancient relationships, solving a 20-year genetic mystery. The finding reveals how social choices shaped human evolution.
The United Nations just launched a worldwide coalition to put human rights at the center of global decision-making. The Global Alliance for Human Rights unites governments, businesses, faith leaders, and everyday citizens around a shared vision of justice.
Actor Ethan Hawke delivered a moving explanation of why AI can never replace human creativity, describing his daughter's imperfect art as more valuable than any AI-generated masterpiece. His response is resonating with millions who worry about technology replacing human expression.
A newly excavated cave in Israel reveals that Neanderthals and early humans didn't just cross paths—they shared tools, burial practices, and possibly symbolic rituals. This discovery rewrites our understanding of early human cooperation.
Four astronauts just broke the record for the farthest distance humans have ever traveled from Earth, soaring past the Moon and witnessing views no one has seen before. The Artemis II mission marks a giant leap toward humanity's return to the Moon and eventual journey to Mars.
Archaeologists in central China discovered sophisticated stone tools dating back 160,000 years, proving early humans in East Asia were just as technologically advanced as their African and European counterparts. The find challenges decades of assumptions about ancient human ingenuity.
New discoveries at an Israeli cave reveal that Neanderthals and early humans didn't just coexist—they collaborated, shared tools, and even buried their dead together. This groundbreaking find rewrites our understanding of human evolution as a story of cooperation, not competition.
Scientists extracted proteins from 400,000-year-old teeth and discovered evidence that our ancient ancestor Homo erectus may have interbred with other human relatives, passing genes that still exist in some people today. This breakthrough shows how modern humans carry traces of ancestors who walked the Earth hundreds of thousands of years ago.
The largest study of ancient human DNA reveals that human evolution has dramatically accelerated since farming began, reshaping everything from disease resistance to physical appearance. Scientists found nearly 500 gene variants that changed through natural selection as our ancestors adapted to revolutionary lifestyle changes.
Researchers gathered in Colorado to seriously plan the first crewed mission to Titan, Saturn's largest moon, marking it as humanity's next frontier after Mars. The moon's thick atmosphere and abundant resources make it surprisingly ideal for human exploration.
