NEW YORK CITY — Tucked away in a building on the corner of 72nd Street and York Avenue in Lenox Hill, an extraterrestrial marvel sits sturdily on a mirrored pedestal. It’s the largest Mars rock on planet Earth — and it turns out its 54-pound (25-kilogram), ashy, terracotta structure isn’t as priceless as you’d expect. This Mars rock is up …

PALM BEACH COUNTY, Fla. – A mysterious and deadly disease is wreaking havoc on nine-armed sea stars along Florida’s Atlantic coast, according to the University of Florida’s Institute of Food and Agricultural Studies (UF/IFAS). In a release last month, researchers confirmed the outbreak of the notorious sea-star wasting disease (SSWD) — a condition known for causing sea stars to develop …

Astronomers have been aware of cosmic vampires, dead stars that hungrily strip plasma from victim stars, for some time. New research suggests that some of these cosmic fiends could have accomplices, Renfields to their Draculas, in the form of a third star in their systems, facilitating their fateful encounter. These systems are known as cataclysmic variables, and their occupant vampire …

It’s a commonly held belief: Sperm cells are like runners in an epic race, competing against each other for access to the coveted egg at the finish line. The egg, in turn, waits patiently for the winning sperm to pierce its outer membrane, triggering fertilization. This narrative of racing sperm and waiting eggs has persisted through time — and yet, …

After the fire and fury of liftoff, when a spacecraft is sailing silently through space, you could be forgiven for thinking the hard part of the mission is over. After all, riding what’s essentially a domesticated explosion up and out of Earth’s gravity well very nearly pushes physics and current material science to the breaking point. But in reality, getting …

A new derivative of ferrocene has 20 valence electrons, challenging the longstanding rule that organometallic compounds can only have a maximum of 18. The researchers highlight that the ligand structure alters the redox properties of the complex, offering improvements for current catalysts and materials. Organometallic compounds – species containing at least one metal-to-carbon bond – are often most stable if …

Many rocky planets from beyond our solar system glow with volcanic scars, yet their crusts sit frozen in place, locked together like a single giant shield. Is it possible that these planets host conditions that would be friendly to life? Matthew Reinhold, a doctoral researcher, and Laura Schaefer, an assistant professor at Stanford University, created detailed computer models showing that …
