Here’s how much fruit you can take from a display before it collapses
About 10 percent of the fruit in a tilted market display can be removed before it all crashes down, computer simulations show.

STEVE and other aurora-like glows perplex scientists with their complex physics
New views of STEVE from citizen scientists keep raising questions about the atmospheric light show — but computer models may offer some answers.

Invisible comet tails of mucus slow sinking flakes of ‘marine snow’
New measurements reveal the gunk that surrounds the particles, an important factor in understanding how the ocean sequesters carbon.

A maverick physicist is building a case for scrapping quantum gravity
To merge quantum physics and general relativity, physicists aim to quantize gravity. But what if gravity isn’t quantum at all?

Before ancient Egyptians, nature sculpted sphinxes. Here’s how
Steady winds can carve landforms called yardangs — thought to have inspired the Great Sphinx of Gaza — from featureless blobs, a new study suggests.

A rare, extremely energetic cosmic ray has mysterious origins
In 1991, physicists spotted a cosmic ray with so much energy it warranted an ‘OMG.’ Now that energetic particle has a new companion.

Light, not just heat, might spur water to evaporate
In experiments, light shining on water as much as doubled the evaporation rate expected from heat alone, hinting at a never-before-seen effect.

A controversial room-temperature superconductor result has now been retracted
The retraction by Nature is the third for beleaguered physicist Ranga Dias, who still stands by his claim of a room-temperature superconductor.

How neutron imaging uncovers hidden secrets of fossils and artifacts
The technique can complement X-ray scanning and other tools to uncover details of dinosaur fossils, mummies and more.

Salty sweat helps one desert plant stay hydrated
The Athel tamarisk excretes excess salt through its leaves. The buildup of salt crystals pulls water directly from the air, a study reports.

Physicists get a first glimpse of the elusive isotope nitrogen-9
With seven protons and two neutrons, the lopsided atomic nucleus of nitrogen-9 pushes the limits of what can even be considered a nucleus.

How quantum ‘squeezing’ will help LIGO detect more gravitational waves
An upgrade to LIGO that comes from exploiting a quantum rule known as the Heisenberg uncertainty principle makes it easier to detect spacetime ripples.
