When scientists disrupted dopamine in hungry rats, the animals still showed pleasure when sweet food was placed in their mouths — they just lost the drive to work for it, suggesting dopamine governs wanting more than enjoyment

The brain's reward chemical may not deliver pleasure at all—it's the engine that makes us crave, seek and strive. The post When scientists disrupted...

One set of simulations suggests Uranus may have been tipped over by at least two giant impacts rather than one: when researchers modelled a single abrupt collision acting on an existing moon-forming disk, the resulting moons orbited backward. Multiple impacts produced a prograde satellite system aligned with Uranus’s extraordinarily tilted equator—but newer models show that a single impact followed by moon formation remains possible.

A 2012 pre-existing-disk model required an earlier tilt to keep Uranus's moons prograde, while later impact-generated-disk models restore a viable one...

A single army-ant colony can move like one creature made of hundreds of thousands of bodies — up to 700,000 workers with no leader, no central plan, and no ant understanding more than the neighbours around it, yet together solving problems no individual could even perceive

Hundreds of thousands of ants with no leader, no plan, and no individual awareness of the bigger picture somehow move and hunt as a single, purposeful...

Mars lacks Earth’s protective global magnetic field, and a 2026 Boston University-led study revealed one consequence: solar-wind shear generates enormous plasma waves that tear clouds of atmospheric ions into space, with instantaneous fluxes 10–100 times greater than typical steady escape channels. Scientists think such events may have contributed to Mars’s transformation from a wetter, potentially habitable world into today’s frozen desert.

Joint MAVEN and Tianwen-1 observations identify Kelvin-Helmholtz wave packets as a bursty route by which oxygen-bearing ions escape the Martian atmosp...

The sharpest-ever images of the Sun, published in August 2026, revealed plasma vortices as small as about 20 kilometres across—structures no previous telescope could resolve. They may help twist and transport magnetic energy through the solar atmosphere, potentially contributing to the still-unsolved mystery of why the corona is far hotter than the surface.

Inouye resolved the photosphere at about 19 kilometres and exposed Kelvin-Helmholtz vortices at magnetic boundaries, but their contribution to coronal...

When scientists announced Webb’s first definitive detection of Neptune’s auroras in March 2025, they revealed another surprise: observations taken in 2023 showed that the planet’s upper atmosphere had cooled by several hundred degrees since Voyager 2 visited in 1989—and scientists still don’t know exactly why.

Webb's 2023 H3+ spectrum measured Neptune's upper atmosphere at 358 plus or minus 8 kelvin, far below Voyager 2's 1989 estimate, but two snapshots can...
