Why Are Some People Left-Handed?

Being a righty or a lefty could be linked to variations in a network of genes that influence right or left asymmetries in the body and brain

A team of Western scientists recently helped local researchers set up monitoring instruments on North Korea's Mount Paektu, an active volcano

Every 11 years, as part of the solar cycle, the Sun’s magnetic field flips, coinciding with a maximum in activity such as solar flares.

The Sun’s Magnetic Field Is About to Reverse

Every 11 years as part of the solar cycle, the Sun's magnetic field flips. What's in store for Earth when the field reverses a few months from now?

What’s Behind That Jellyfish Sting?

If you're headed to the beach this weekend: with Jellyfish populations rising, what should you do if you are stung, and why do stings hurt so much?

Greenland may eventually resemble the lush Tongass National Forest in Alaska.

Climate Change Will Green Greenland

Many species of trees and shrubs may take up residence in formerly frozen Greenland, transforming parts of the island into a lush landscape

Astronomers traced 2011 QF99, circled in green, across the sky to find that it shared an orbit with Uranus.

A small asteroid that orbits ahead of the seventh planet offers a clearer picture of the ongoing celestial pinball game in the solar system's outer reaches

Each crane is tagged with a radio transmitter (shown on the bird’s left leg) to monitor its location.

Nurture, Not Nature: Whooping Cranes Learn to Migrate From Their Elders

New research shows that the endangered cranes learn to navigate thousands of miles by taking cues from older birds

Could life on Earth have been born on Mars?

Did Life Come to Earth From Mars?

Mineralogical clues point to the idea that the early Earth, starved of oxygen and submerged by a vast ocean, needed molecules from Mars to kick start life

New research shows that abnormally cool waters in the Pacific, part of a natural cycle, have masked the warming we should have seen due to greenhouse gas emissions. When the waters go back to normal, global warming will likely accelerate.

Why Global Warming Has Paused—And Why It Will Soon Start Up Again

Abnormally cool waters in the Pacific, part of a natural cycle, have masked the underlying warming caused by humans burning fossil fuels
