More than 150 companies are developing flying cars. Here's why they're aren't yet off the ground and darting across city skies.

How to see through the lies that surround us.
sleep sound
the human brain remains highly responsive to sound during sleep, but it does not receive feedback from higher order areas — sort of like an orchestra with “the conductor missing.”
The world is aging, and with age comes vision decline. New research may have found how to improve eyesight in an accessible way.
More humans are being born with a third arm artery, an example of microevolution happening right before our eyes.

Rituals come as much from religion as they do from the way Earth spins around the Sun.
eagle nebula stars
Even though the leftover glow from the Big Bang creates a bath of radiation at only 2.725 K, some places in the Universe get even colder.
The serotonin theory of depression started to be widely promoted in the 1990s, coinciding with a push to prescribe more SSRIs.
instructional design models
There are dozens of instructional design models, but most learning designers rely on a select few. Here are four of the most common.
From Amazon to the US Army, everybody wants one (or 150).
time dilation
We live in a four-dimensional Universe, where matter and energy curve the fabric of spacetime. But time sure is different from space!
The costs of such an endeavor would be extremely high, while the potential payoffs would be uncertain.
There's a speed limit to the Universe: the speed of light in a vacuum. Want to beat the speed of light? Try going through a medium!
Deliveries of the $250k Lightyear 0 will start in November 2022.
Cement production currently accounts for 8% of global carbon emissions.
MIRI
Take a peek at the pre-release images used to calibrate and commission JWST's coldest instrument, now ready for full science operations.
salton sea
A team of scientists hopes deep-earth lithium could sustain America's vast demand for batteries. But extracting it won't be easy.
length of day
The length of a day oscillates slightly every six years. This was a surprising discovery made last decade. We might now know why.
Livestock now outweighs wild mammals and birds ten-fold.
night vision
Deep learning AI has accurately created color images from night vision images.
Scientists have found three new examples of a very exotic form of matter made of quarks. They can yield insights into the early Universe.
Myrkl (pronounced "miracle") is supposed to let you go wild without facing the consequences the next day. But does it actually work?
alien contact
The psychology of alien contact largely revolves around the concept of "otherness." We need to learn to be comfortable around strange things.
mammals
Mammals have a history stretching back 325 million years. To study that ancient history is to know our own origins.
big crunch
It started with a bang, but won't end with one. Instead, it will "rage against the dying of the light" like nothing you've ever imagined.
stars die
Like humans, stars die. The James Webb Space Telescope's early images already give us a lot of information about how this happens.
futurama
The fictitious 31st-century world portrayed by the series is actually quite a bit like our own in the 21st century.
jwst deep field
Even with only 12.5 hours of exposure time, James Webb's first deep-field image taught us lessons we've never realized before.
astronomy new era
Astronomy's roots rest in the very origins of humanity. We have always looked to the skies for answers. We are starting to get them.
