What defines a species? Inside the fierce debate that's rocking biology to its core
(Maria Klos for Live Science)
What defines a species? Inside the fierce debate that's rocking biology to its core
In 2016, scientists published a paper with a bold claim: that the giraffe, first described as a species by Swedish biologist Carl Linnaeus in 1758, might actually have been four species all along. Unlike Linneaus, the researchers had access to modern genetic tools, which revealed that giraffes fall into distinct clusters based on differences in their DNA, some of which are "larger than the differences between brown bears and polar bears," the authors said at the time.

The news sent ripples through the giraffe conservation community, which suddenly needed to protect four species instead of one. But from the start, there was disagreement about this new classification, and even today, the International Union for Conservation of Nature — an organization that oversees the listing of threatened and endangered species — lists the giraffe as a single species, Giraffa camelopardalis, with nine subspecies.

The dustup and others like it highlight the "species problem," a fundamental uncertainty over how we parse organisms, and it continues to rile biologists the world over. So what defines a species, and why does this matter?

A less densely packed galactic core could mean that the Milky Way’s mass is lower than estimated, which in turn could imply that it holds more dark matter than originally thought. (Getty)

Discovering the secrets of the sun's magnetic field

(NASA SDO)
The Solar Dynamics Observatory (SDO) is a NASA mission designed to study activity on the sun, learn what drives that activity, and explore its impact on space weather, which can ultimately result in dramatic geomagnetic storms on Earth.

(Collins Aerospace)
Collins Aerospace has exited a contract to develop new spacesuits for NASA following talks with the agency. The contract was part of the xEVAS program, which saw awards to Collins and Axiom Space to develop up to four new spacesuit designs for both the International Space Station (ISS) in low Earth orbit and the Artemis moon program. Collins was to design suits for the ISS.

Mars Odyssey celebrates 100,000 orbits
Mars Odyssey celebrates 100,000 orbits
(NASA/JPL-Caltech/ASU)
NASA's Odyssey spacecraft, the longest-running mission at Mars, circled the Red Planet for the 100,000th time today, the mission team announced. To celebrate the milestone, the space agency released an intricate panorama of Olympus Mons, the tallest volcano in the solar system; Odyssey captured the view in March. The volcano's base sprawls 373 miles (600 kilometers) near the Martian equator while it soars 17 miles (27 kilometers) into the planet's thin air. Earlier this month, astronomers discovered ephemeral morning frost coating the volcano's top for a few hours every day, offering fresh insights into how ice from the poles circulates throughout the parched world.

For more than a decade, Mongabay was just a two-person operation. I never imagined the growth that would unfold over the next 25 years and the impacts we would collectively achieve.

Today, more than 100 staff and 1,000 contributors report from Nature’s frontline. As a global newsroom, Mongabay makes science accessible and elevates the voices and knowledge of people directly impacted by environmental change.

As our jam-packed summers unfold, our team has been dreaming of our next big adventure.

Some of us are thinking about shaking up our family holiday traditions (and others are already scheming how to get out of them…).

We’ve put together some trips below that can get you away this year. Have you ever traveled out of the country for the holidays?

After 24 hours of travel, in the eastern sky on Tuesday morning, July 2, the now-thinner crescent of the waning moon will shine less than a binoculars' field of view (orange circle) to the upper right of Messier 45, the bright little Pleiades star cluster. The faint, blue-green dot of magnitude 5.8 Uranus will be positioned several finger-widths to the moon's lower right (or 3 degrees to its celestial south). Uranus is visible in binoculars.

Why puffy exoplanets often dance with perfect rhythm
Why puffy exoplanets often dance with perfect rhythm
(NASA, ESA, CSA, and D. Player (STScI))
Though notably absent from the solar system, the most common planets in the Milky Way are known as "sub-Neptunes," or worlds with sizes between those of Earth and the ice giant Neptune. It is estimated that between 30% and 50% of sun-like stars are orbited by at least one sub-Neptune - but despite these worlds' ubiquity, scientists studying extrasolar planets, or exoplanets, have traditionally had difficulty measuring sub-Neptunes' densities.
