Science & Education

Hank Green explains why quality educational content can't survive market economics, and why he converted Complexly to a nonprofit to protect Crash Course.

Physicists debate whether reality needs 3, 2, 1, or 0 fundamental constants, with a new argument claiming clocks alone can measure everything.

A new study claims one molecular chirality transports electrons better, potentially explaining why all life uses the same-handed molecules — but the physicist host is skeptical.

Mosul Dam earned its 'most dangerous' title because its gypsum foundation dissolves in water, requiring a $500M grouting overhaul to prevent catastrophic collapse.

The Iran war-triggered oil shock is accelerating renewables in some countries but exposing how policy failures, market structure, and fossil fuel profits undercut the clean energy transition.

A 2025 Nature ranking reveals the five most-cited scientific papers ever, spanning materials science, computer science, physics, biology, and chemistry.

Global fertility is collapsing toward civilizational crisis, driven by cultural shifts, economic structures, and gender politics — not simply affordability.

Expose yourself to real social situations rather than simulations, because social anxiety stems from mistaken beliefs about rejection that direct experience corrects.

Casimir Inc.'s claim to harvest unlimited energy from the quantum vacuum violates basic physics — the Casimir effect cannot produce continuous energy.

F1 gearboxes evolved from bleeding-hands manual shifts to seamless 3-millisecond changes by briefly engaging two gears simultaneously without destroying the drivetrain.

Physicists propose that next-gen aluminum-ion atomic clocks can detect whether quantum superposition causes time itself to run at multiple rates simultaneously.

Wanted children reliably increase happiness, but unintended fertility, broken dating markets, and demographic collapse demand urgent practical solutions beyond just debating the data.

A 2025 study links a massive 1345 volcanic eruption to crop failures and grain trade that accidentally shipped plague-carrying fleas into Europe.

Donald Hoffman argues conscious agents are fundamental reality, spacetime is a rendered headset illusion, and science can decode the software layer beneath it.

A temporary video comparing the creator's Artemis calendar photo picks against 578,000 community votes, posted for only a few hours before deletion.

Fractals revolutionized technology by enabling multi-frequency antennas, efficient cooling systems, medical diagnostics, and procedural world generation in games like Minecraft.

Subcritical reactors eliminate runaway nuclear reactions by using an external neutron beam — switch it off, and fission stops immediately.

Dubai's explosive growth outpaced its sewage infrastructure, forcing a $21.8BN tunnel megaproject to fix a crisis decades in the making.

Urban raccoons may be developing shorter snouts near humans, a trait linked to domestication syndrome, though researchers stress they are far from domesticated.

Security experts break down the unique crowd management challenges of Copacabana Beach concerts, covering barriers, sand surfaces, and free-entry unpredictability.
