When it comes to successful fertilization, zero gravity means zero game, a new study suggests. When looking at sperm and eggs in simulated microgravity, scientists found that this environment hampered sperm navigation, fertilization and embryo…

Human sperm get lost in space, pioneering study finds

Sperm in space are likely to get disoriented and lost while struggling to find their way to an egg, a new study has found.

When exposed to microgravity in experiments, sperm tumble around like an untethered astronaut, according to Adelaide…

A trip to space could very well leave human male sperm stumbling about in the dark, chasing their tails.

Researchers at Adelaide University in Australia have shown that in the lab, a lack of gravity can work against our gametes – a possible…

Scientists have uncovered a massive water reservoir deep beneath Earth’s surface, contained within a mineral called ringwoodite. This “ocean” is three times larger than all of Earth’s surface oceans combined, and it is located about…

A new era in mathematics may be on the horizon—one that some researchers have long desired. Mathematicians could soon use computers to verify proofs quickly and rigorously, ensuring published proofs are correct and providing a foundation for…

A small asteroid about the size of a car flew close to Earth overnight Tuesday, giving scientists another chance to study objects that pass near the planet. The space rock, known as 2026 FM3, made its closest approach on March 24-25, according to…

Stunning new views of Saturn offer the most detailed portrait yet of the ringed planet, showcasing the combined power of NASA’s most advanced space telescopes.

Using observations from the James Webb Space Telescope (JWST) and the Hubble Space…

Mathematicians are threatening to boycott the field’s largest, most prestigious gathering this summer if it takes place in the U.S., as currently planned.

Every four years since the turn of the twentieth century, the International Congress of…

In 2021, dermatologist David Ozog was on holiday with his family in the Bahamas, when his 18-year-old son had a massive stroke. The teenager was airlifted to Florida, and then to Chicago for surgery. As his son was lying partially paralyzed in a…
